If you want to extend the Free Pascal Compiler to work as a translator for Free (Object) Pascal to Java (Programming Language), you are welcome. If you achieve this, and later want to extend the Lazarus development environment for your FPC extension, you are also welcome. Visual Studio has a .NET mobile emulator where you can make a mobile application, and run it in the emulator.

I'm not 100% convinced that it can't be abstracted just like if it was just another platform. There is a JVM assembler: http://en.wikipedia.org/wiki/Jasmin_%28Java_assembler%29 But, the main problem with the Java ENVIROMENT/FRAMEWORK (Virtual Machine + Standard Library + Programming Language + else), is that is 100% CLASS/OBJECT oriented. Even the JVM assembler works with objects and classes, you can't work with global functions, records, or variables like many of the LCL functions does. As mentioned in other replies, you'll have to mutilate the object pascal version of the language to make it run in a JVM. Trying to migrate the Free Pascal Compiler (FPC) used by the Lazarus could be possible, but with weird, unexpected, poor performance results... Borland/CodeGear make an experimental Pascal for JVM compiler, and both this version and its .NET compiler had pitfalls. Anyway, virtual machines are slow, don't matter how much optimization they have, and require more resources. And mobile devices don't have as many resources that a P.C. does.

[lazarus] Making the IDE work with C/C++
Hi. One of the things I think It may be considered to do a Lazarus C++ IDE, instead of a Lazarus Free Pascal IDE, is that C/C++ uses header files. So you'll have to work with both the header and the source file, instead of a single file. Another, will be the data types. By example, I once had to migrate a delphi component to a CBuilder component, and discover that delphi/lazarus set of type didn't exist. I had to use an existing generic template instead. Altought, Lazarus is a Free Pascal related project, the truth is that, the need to share the same software libraries, modules or packages, using different programming languages for the same project is required. Many talented programmers/developers don't use the same programming language, many companies doesn't have the resources to migrate the payroll DLL to a new programming language (example C - Free Pascal). So the idea of Lazarus supporting other programming languages, may sound bizarre, at first, but realistic, at last... I always try to avoid confusing the programming language term, with the programming environment, instead. That's why M$ got right it's .NET framework v.s. SUN's Java. .NET uses the same library, same development environment, different programming language (VB, C#, COBOL, etc).

Is true that The project doesn't grow as fast as others, but the
people that makes contributions, have make it use useful.
Since some features are not fully implemented, compared to Delphi (c)
is possible that your student/coworkers find it difficut to use.
I have many personal projects products made in Delphi, that I need
to migrate to Lazarus. Since some controls/components aren't available
in Lazarus,
I understand the difficulty you mention...
In my opinion, the multi-platform support of Lazarus is a big pro.
And also its open-source character.
Many of the features features that aren't available in commercial IDES,
are available in Lazarus, thru Open Source.
Example, English ISN'T our native language, and in both commercial
education area, this is a problem.
Many program development tools are still in english.
But many Open Source applications allow us to change that,
such: Lazarus
I am interested in collecting experiences with using Lazarus in
education, in particular as a tool of primary choice for programming.
Let me hear those success stories, so I convince others ...
My comment It may not be what you expect, but, I hope it helps.
Let me tell you more about (Free) Pascal than Lazarus (IDE).
We have the opposite situation.
I learn programming in Turbo Pascal/Delphi. Many schools here, are
following the C#/Java hype, or using the Pascal is obsolete
paradigm used by C/C++ developers .
Schools people are avoiding any use of other tools except C#/Java.
At my job, I currently work with both C#/Java, and many of my younger
coworkers DOESN'T HAVE THE PROBLEM SOLVING AND PROGRAMMING SKILLS
requiered for the job.
When I ask them which programming languages AND Methodologies, ALL OF
THEM mention Java or C#, or C/C++.
Lazarus (IDE) Delphi are built from people who knew Object Pascal.
It's weird to see software developers that just finish school,
know things like Unified Modeling Language, X.M.L., Rational Unified
Process, BUT when they struggle to to make an application to work...
Niklaus Wirth, they guy that invented Pascal,
created the language in order to make developers
adquire solving problem skills.
It isn't about using { and } instead of begin and end.
It's about having a programming language that allow you to solve
a solution by building an application...
In Lazarus, may be things under construction, but don't let your
students/coworkers migrate to other tools that doesn't
allow them to develop the skills THEY WILL NEED IN THE JOB MARKET,
EVEN IF LATER THEY HAVE TO WORK IN C# OR JAVA !!!
Good Luck ;-)

The goal in doing so would be using a specialized macro processor
I'm surprise for your question, because I started been interested in
language/compiler design because I wanted a preprocessor for Turbo
Pascal,
like Turbo C++ ;-)
Let me understand, you already have the preprocessor to transform your
Pascal with Tags into a Pascal without tags source code file ?
Something like:
-
program PreprocessorExample;
#define Pi 5
begin
Write('Pi value is ', Pi);
end.
-
Into something like :
-
program PreprocessorExample;
begin
Write('Pi value is ', 5);
end.
-
replacing tags in the source code before feeding through fpc.
Based on my experience, I have 3 ideas.
Idea 1:
Consider your Lazarus Free Pascal with preprocessor project
something different than a standard Lazarus Free Pascal project. And
by that, I MEAN, USE A DIFFERENT FILE EXTENSION.
*.pas - *.mpas
M stands by macroprocessor
Later, you may add a plug-in or menu option to Lazarus IDE, for that,
you'll need help for the rest of the Lazarus community.
That plug in will first call the preprocessor library, and if there is
not any error, later call FreePascal Compiler (PFC) included in
Lazarus IDE
Idea 2:
Let your project keep the standard extension and project type, and add
a plug-in to Lazarus IDE, that calls your preprocessor.
Idea 3:
No preprocessor at all.
Pardon my curiosity, but what do you need a preprocessor for ?
Since including a preprocessor or other tool may have some complexity, you may
consider solving your problem using another tool.
Just my THREE cents.

Quoting Kris Leech [EMAIL PROTECTED]: is create something for FPC/Lazarus which is similar to a SFS (Single File System) so all files are stored as a byte stream in a single file. Micro$oft call this Structured Access instead of Virtual File System. Other people use the words Virtual File System for other similar stuff, but the one you are using is OK. then how to use that byte stream with other functions etc. that do not take TStream as input. OK. Standard file operations (Reset, Rewrite, Close) are easier to learn than stream classes. BUT, doesn't allow to extend or customize file access, so, forget about File Of MyType. Streams are better to customize for custom situations, like Virtual FileSystems. A third option, would be to create your own File type record and create its own functions. I DID THIS. Any ideas you have or have previously implimented would be great to hear. OK, I wanted to do the same thing. Any O.S. has its own standard libraries to access its Standard File System. In windowze, it's called O.S - A.P.I. (Operating System - Aplication Program Interface) To get to the point, I DID THAT, a set of libraries/functions, for a custom Virtual File System. Let me tell you how I started: 1. Create a custom System unit: -- unit MyVFS; interface ... implementation ... end. -- 2. Add the standard functions/procedures, and make the wrappers first, and the internal code, later: -- function FileExists(const Path: string): Boolean; begin Result := false; // to-do... end; function DirExists(const Path: string): Boolean; begin Result := false; // to-do... end; procedure CreateDir(const Path: string); begin // to-do... end; procedure DeleteDir(const Path: string); begin // to-do... end; procedure DeleteFile(const Path: string); begin // to-do... end; procedure RenameDir(const Source, Dest: string); begin // to-do... end; procedure RenameFile(const Source, Dest: string); begin // to-do... end; procedure CopyDir(const Path: string); begin // to-do... end; procedure CopyFile(const Path: string); begin // to-do... end; -- There is more things to do. For example, how are you going to write a path ? MS-DOS/Windowze style: c:\mydocs\myhomework.txt Unix style: /public/mydocs/myhomework.text Do you want to continue with the code ideas I sending you ? Do you want to try another stuff by your self ? driver for Win32 and Linux to allow proper OS access to the SFS... Then they would work like native files. I think the drive aproach is VERY difficult.

Quick-Easy Answer: No. Any class (like TFileStream) is stored different in memory that a File type. Long-Difficult-Boring Answer: We call, sometimes, a File variable a pointer in terms of a concept. But, a File variable, speaking technically, isn't a pointer but a record. Suggestion: Why don't you use a TFileStream and its methods instead ? Or if you prefer, you may make your own unit, in order to use a TFileStream variable/object as it was a File variable and the methods you are use to. Example: --- Unit MyFileUnit; interface type TMyFile = TFileStream; procedure Assign(var F: TMyFile; FullPath: string); procedure Reset(var F: TMyFile; RecordSize: Integer); procedure Rewrite(var F: TMyFile; RecordSize: Integer); procedure Append(var F: TMyFile; RecordSize: Integer); procedure Close(var F: TMyFile); implementation procedure Assign(var F: TMyFile; FullPath: string); begin ... end; procedure Reset(var F: TMyFile; RecordSize: Integer); begin ... end; procedure Rewrite(var F: TMyFile; RecordSize: Integer); begin ... end; procedure Append(var F: TMyFile; RecordSize: Integer); begin ... end; procedure Close(var F: TMyFile); begin ... end; end. --- Just my 2 cents. maramirez _ To unsubscribe: mail [EMAIL PROTECTED] with unsubscribe as the Subject archives at http://www.lazarus.freepascal.org/mailarchives
Re: Free Pascal widget set
Using C++ libraries from other languages is either bloat or hard to use. In theory, many C++ libraries should be faster, in practice they're not. This is due to the fact that many C++ developers are just to desperate to start programming, skipping the design process. Remember that Pascal was originaly designed to help students to learn programming, wheter structured programming or object oriented programming... I haven't try the libraries you want to use for your custom widgetset, but if you think they're good, and want to migrate them from C++ to Free Pascal, well, Good Luck !!! - Marco Aurelio Ramirez Carrillo lazarus dot mramirez at star-dev dot com [dot mx] _ To unsubscribe: mail [EMAIL PROTECTED] with unsubscribe as the Subject archives at http://www.lazarus.freepascal.org/mailarchives

Re: [lazarus] converting delphi components to lazarus?
Hi.
I wrote some components for use in delphi,
Im also starting to migrate my delphi components to Lazarus.
is there any special things to note in conversions?
First, of all, by components do you mean Visual controls or
just drag and drop non visual components ?
The first thing you may encounter is that the packages where
the components are stored, in Lazarus are STATICALLY compiled,
that means there're NOT DLL (shared libraires) like windowze.
That means you have to compile Lazarus IDE with your component's
packages in order to use them in Lazarus.
As they are visual and do respond mostly to lots of windows messages?
Yes, windowze messages doesn't exist in Linux.
You will have to change the message handlers procedures in your
control's code to be message-independent.
Example:
Original code:
type
TMyControl = class
procedure WMSize; message WM_Size;
end;
procedure TMyControl.WMSize;
begin
// ...
// my stuff to answer to WM_Size message.
end;
To temporal new code:
type
TMyControl = class
procedure WMSize; message WM_Size;
procedure DoSize;
end;
procedure TMyControl.WMSize;
begin
DoSize;
end;
procedure TMyControl.DoSize;
begin
// ...
// my stuff to answer to WM_Size message.
end;
Try this first, in your DELPHI code. When you have this modifications,
working in Delphi, then you can make your code platform independent.
Example:
Temporal new code:
type
TMyControl = class
{$ifdef Windowze}
procedure WMSize; message WM_Size;
{$endif}
{$ifdef QT}
procedure QTSize;
{$endif}
procedure DoSize;
end;
{$ifdef Windowze}
procedure TMyControl.WMSize;
begin
DoSize;
end;
{$endif}
{$ifdef Windowze}
procedure TMyControl.QTSize;
begin
DoSize;
end;
{$endif}
procedure TMyControl.DoSize;
begin
// ...
// my stuff to answer to WM_Size message.
end;
It's not exactly, but it's the general idea.
You'll have to check Lazarus and FPC documentation, to find
each winzowze message equivalent.
and if i just wanted it to be working on win32 also should i change
things?
Yes, I started to migrate my components in Kylix, and it was the same
problem.
Just my 2 cents.

Re: [lazarus] Who needs Unicode controls.
UTF-16 is multibyte. There are more unicode characters than 2 byte numbers, so you won't find a complete 2 byte unicode encoding.

Take TEdit for example, which has been extended to contain properties like the Font property. Ok, you were making reference to the controls design, not the character enconding... Yes, I get, I know about OOP principles. Actually once I try to make a TFont descendant in a visual control, but It didn't allow me to replace. Actually, the Font property in visual controls, as an example of composition wasn't very well design it.

Re: [lazarus] Who needs Unicode controls.
The question is: should the LCL use the 'native' string type and let the
applications write three times the code. Or should the LCL use UTF-8 and
map internally in the interfaces and let the applications write once and
compile anywhere.
Maybe BOTH STUFF.
There are some O.S.'es that support some kind of Unicode, others no.
The ideal scenario will be that Unicode was supported by the O.S.
(files, functions A.P.I.) and that programs just use that support.
Maybe we could have 2 sets of libraries, one for native support
and other for non-native support and wrapped them in a library:
-
MyProgram.pas
-
program MyProgram;
uses
(* System, *)
Unicode,
Crt;
{#define NativeUnicode}
var
F: File of WideString;
S, D: WideString;
begin
AssignFile(F, 'MyUnicodeFile.txt');
Reset(F);
while (not EoF(F)) do
begin
ReadLn(F, S);
D := Unicode.Uppercase(S);
WriteLn(Crt, D);
end;
Close(F);
end.
-
-
Unicode.pas
-
unit Unicode;
interface
(*
type
WideString = ...;
// defined by compiler
*)
implementation
uses
{#ifdef NativeUnicode}
Native,
{#else}
NonNative,
{#endif} (*NativeUnicode*)
;
function Uppercase(const Value: widestring);
begin
{#ifdef NativeUnicode}
Native.ToUpper(pchar(Value), pchar(Result), SizeOf(Value));
{#else}
Result := NonNative.Uppercase(Value);
{#endif} (*NativeUnicode*)

end.

Re: [lazarus] Re: Who needs Unicode controls.
Well the only solution i see is something like tnt componenets. Maybe, and have an especial property editor for those wide properties, since the text property cannot be used directly. using encoded string you have to decode them and then use those functions! Some applications on windowze require encoding/deconding functions as well. You see, some documents are stored in a multibyte Unicode format (UCS-16, some letters use several bytes others use 1 or 2 bytes), and in application uses same byte count Unicode format (UTF-16, all letters use the same numbers of bytes).

[lazarus] Lazarus Help System Requirements
Overview Hi, I started a new thread in order to summarize the comments about a Help System or Help File Format for Lazarus, or even FPC. Sorry, but I think the Re: [lazarus] New help doc format? thread was getting to big, and focused in how to implement a help system, and forgot the what does a help system has to do. I already have the same problems with Delphi or Kylix, AS WELL AS MANY OF YOU and have to deal with the same topics: Lazarus Help System Requirements 1. Cross Platform - Windowze has 2 help system versions (*.hlp files and *.chm files). Un*x based systems have man (doesn't have links, discarted, sorry). I heard that *Linux (GNU/Linux, and others) doesn't have one. It seems to me that many of you use Lazarus as a Delphi Just for Linux, instead of Alternative to Delphi available in several platforms. But the point is that there are several ports (Mac, mobile, *BSD), amd also, several of us HAVE TO WORK WITH Windowze and Linux, at the same time, and that ALSO APPLIES to the help system. A true Cross-Platform Help System must be available in SEVERAL PLATFORMS AT THE SAME TIME. A fast and dirty solution could be to use a source file format, (HTML, XML, perhaps ?) and compile it into an existing destination native file format (*.hlp or database file) that it's displayed in existing, maybe propertary, help viewers. The other (slow and clean) solution, create a whole new file format (Small Database/XML based ?) and built new help viewers. 2. Offline -- Many of us doesn't have or can't have Internet on the work or school. Wiki pages and HMTL files on the web are great, but we still need to have a help system that can be used on our home PC. Yes, I know we can have local HTML files. In case we use HTML or XML files for the help system, we need to take this on consideration. 3. Localization --- Some of us doesn't use English as our every day work language or even have to work with several languages at the same time... So the help system have to be localizated. Quick and fast solution, use a source help file and traslated to other languages. 4. Open Standard and Open Source I found, once, a help system that worked on Linux, (http://www.helpblocks.com/), but was proprietary, and doesn't solve the other requirements problems. Third-Party modules (librarys, units) may be necessary, even if they're difficult to use, but they must be open source also. So, the file format must be an Open Standard. Comments Please feel free to add any missing requirement.

Hi.
What they need is people. They (we?) don't need a foundation to make a
better website, but we need someone to make a better website. Obviously
the core developers don't care much about that. They have other
interests.
Your idea of, making some improvements to the community as an alternative
of a foundation, sounds good...
some programmer himself, to do the job? Just like Redhat does?
I thing I got misunderstood on this. First I didn't tought of a foundation
just as way of getting money, but of providing serveral resources
(not just money).
If you have a software-development company, and you need something in
Lazarus/FPC, you can just develop it yourself, instead of giving money.
Just if I have time...
By example, I have a message dialog component in Delphi,
that can be localizated, and it's better to use in code,
example:
Standard message function:
uses
Dialogs;
...
if (Application.MessageBox('Title', 'Message', [mbOk, mbCancel] = mrOK)
then
And my replacement
uses
sdvMsgBox;
...
if (MessageBox('Title', 'Message', [moOK, moCancel] = moOK)) then
And the message box appears in a desidered language. But need
some time in order to ported to Lazarus.

Maybe.
time instead. That's far more usefull.
Personally, im working on that... ;-)
Since 2 years ago, I already have some projects that have to migrate from
Windoze to Linux, libraries, components and so on,
but at that time Lazarus was too inmature,
and I didn't time to help.
Luckily, Lazarus have get better, (thanks to the developers that supported).

There are 10-20 messages everyday there. Then, I have to take another look... I prefer mailinglist I think forums, wiki or mailinglist, depends on the subject. Lazarus (as an IDE) topics are better in the mailing list. Starting a foundation isn't a big deal overhere. It only cost you a few eur a year. But I don't see the need for it. Maybe. The latter is more important. Time, or the will to make time. Or the boss/employer/company allows to do so... I have check the roadmap, since a year ago, and there a few things I would like to contribute, but same problem with time like other developers. Im not a troll or guy just trying to make trouble, but have the same problems of time that many of you around, here. I was thinking that a foundation with a core of developers, among other things, may help improve the project, but it seems I WAS WRONG... what will a foundation offer for those outside the us ? The foundation, not directy, but by providing more resources to the project, other poeple's work will improve, like documentation, unicode support and so on.

Re: [lazarus] Lazarus Foundation pros
Hi. Lazarus or FPC do not have administration, leadership, control, resources, etc. Wait, this isn't a flame war Lazarus does administration and the other stuff, but I think there's a point where all this stuff may get slower, if you get the idea. Metaphor: The same way there's a limit to a person running speed, and a car can surpass that limit, the same way, a foundation may surpass a community... incorporate or create a legal organization it will get totally complex. I understand and Im agree with that, but still, if the foundation is well strutured, may get more benefits over the difficulties of the complexity. Of course, a foudation may be difficult thing to start. does that mean? Maybe I should rephrase that, forums are updated, the website is fine, but many guys prefer to reply or ask into the mailing list. The relation to the foundation, is that maybe a foundation may coordinate the developers to promote the website, the forums, the wiki page, and the mailing list in way that developers may use each tool better. So why don't you have it in the forums? Because I have seen that previous questions of mine, and question from other guys, didn't get a reply... This is not the webmasters fault, this is a thing in the Lazarus community. What makes your think Lazarus is any more complex then the FPC compiler that I don't mean that crafting a compiler is a trivial task !!! Actually, I have make some compiler stuff, I know its DIFFICULT, but since Lazarus uses the compiler plus other stuff, well, it adds complexity to that... it. Im not taking of selling Lazarus, Im talking about providing more resources to the project (time, developers, tools). Im interested in Lazarus both as a hobbie and work. In my case, I use programming tools, because Im a programmer, I pay the rent from that ;-) But most of the projects you mention don't even have full time developers. They do. Maybe just 2 or 3, that help coordinate the work of volunteers... (Confirmed in the websites, but dont have the info right now) How? You make this global statement but don't give specifics. How exactly does it help? Sorry, Im just trying to start the idea, I dont have all the info by myself right now ;-) That's why also post this on the mailing list... Thanks for your critics. I hope my answers help the project, even if there's not a foundation ;-) - Marco Aurelio Ramirez Carrillo [EMAIL PROTECTED] [.mx] _ To unsubscribe: mail [EMAIL PROTECTED] with unsubscribe as the Subject archives at http://www.lazarus.freepascal.org/mailarchives

Mensaje original Asunto: Re: [lazarus] Lazarus Foundation pros De: Flávio Etrusco [EMAIL PROTECTED] Fecha: Mie, 26 de Abril de 2006, 4:35 pm Para: lazarus@miraclec.com -- Hi I guess the discussion is more about letting someone who the main developers trust to work on such thing, not about programmers/hackers doing annoying-irritative-pita burocratic work ;-) Its, more like that, check my last answer to Michael, one of Lazarus founders. Neither do I. Again, my mistake, forums are updated, but many developers doesn't participate on them :-( I guess he's not a CS bachelor student ;-) (Nor is he very interested in compilers...) Ops, Im thinking about thinking well my comments before writing them. Actually my degree thesis WAS ABOUT COMPILERS, I have made some traslators and interpreters (XML, HTML, C++), I know how dificult job is it. Lazarus (a developer framewok, GUI) adds more complexity to the existing complexity of the FPC compiler. Some guys (3, I think) reply to me that FPC project DIDN'T NEED a foundation, so I reply that a foundation may help Lazarus. The guy at miraclec has done a great job on keeping the project alive, (thanks Michael), but, projects like Lazarus are difficult to maintain, they not a trivial task, neither a compiler does... Metaphor: Fathers sometimes worry about their children independence, mua get them into trouble, I think Michael does cares about Lazarus ;-) I can't reply to every message, but yours and Michael was a MUST.

Re: [Fwd: Re: [lazarus] Lazarus Foundation pros]
This means we need more people who do not necessarily need to write code (patches) or documentation, but do have knowledge about all kinds of lazarus features (by using it themselves regularly for example), and can help users with their problems. Micha Hi. By developers, I don't mean developers that update Lazarus IDE, or Lazarus Control Library (LCL), but, developers that use Lazarus for their own programs. I think wiki and mailing list should be aimed more to Lazarus and LCL developers (that modify Lazarus), altought Lazarus users (developers that use Lazarus) are welcome. I also think that forums should be aimed to Lazarus users (developers that use Lazarus) to help themselves, and again, Lazarus and LCL developers (that modify Lazarus) are welcome. Borland's Delphi documentation mentions Delphi developers, which are VCL users (use controls but doesn't develop them) and VCL developers (develop controls), as well.

[lazarus] Lazarus Foundation pros
Lazarus Foundation (pros) advantages and disadvantages I think that the 2 main reasons that support a Lazarus/FPC foundation are: - Organization - Donations Before I continue, let me say that I thanks all the guys in this community for their work, and any comment I make, it will be as a positive critic. I want to get Lazarus To get better, no to start a flame war... Organization. By organization, I mean administration, leadership, control, resources. I see a foundation as a natural evolution of a open source community, examples: -Open Office -Apache -GNU There's a lot of things where a legally established foundation can do, that a community may lack. For example, I surprised that Lazarus forums aren't updated as it happens to Borland's groups (Delphi and others) or M$ groups... I find the mailing list/wiki very useful for bugs and improvements, but not good for common questions, (like what do I need to install it in certain Linux distribution), which I think it's better in a forum. In fact, this topic, I think it should be in a working forum ;-) I understand also that making a foundation work is not a trivial task, and it needs several things, in order to make it work. Many guys think that the FreePascal project doesn't need a foundation, but the complexity of Lazarus does. Donations. Money is required for several things. Money serves a wildcard for several things like time (hiring developers time), material resources (like cpus, servers, merchandising/publicity) As an example, a few months ago, Open Office development (version 2), a wide used open source software, has halted by lack of developers, until Google make a donation. Personally, my participation in Lazarus development, is very poor, due to my work and lack of time. I guess that some of the guys around here have the same problem, and a set of full-time core developers could help a lot. Other. Lazarus was a must for me (not in US), since a few years ago, due to the high price of Delphi, lack of localization, and dificulty to port to other OSs like Linux, BSD or mobile, not just for cheaper OSs or money, but for technical reasons. Just check how many post are from people from outside US. A foundation can help on this and more matters.

Re: [lazarus] Lazarus in Google summer of code 2006 ?
Hi. http://code.google.com/soc/mentorfaq.html Ops, no money, sorry. If yes, what project would you like to see done for lazarus ? Dynamic package linking ? Would you be interested in a whole ressource editor intégrated into the ide or in a separate tool ? (icons/xpms/bmp/windows ressources/etc...) Separate tool, It's better it's development at start. You may added to Lazarus IDE later, or create a lite version. You may also add a menu shorcut to the IDE, as it happens to the Database Explorer Program in Delphi. Good Luck !!! _ To unsubscribe: mail [EMAIL PROTECTED] with unsubscribe as the Subject archives at http://www.lazarus.freepascal.org/mailarchives
[lazarus] Lazarus/FPC Foundation
Hi, everyone. I read a post about Google Summer of Code 2006 and Lazarus project resources, and I wonder, is there a Lazarus Foundation or FreePascal Foundation ? I have check both websites, and we have both (open source) communities, but legally speaking, I haven't found any foundation. In case there, isn't. What do you think of making one ? - Marco Aurelio Ramirez Carrillo [EMAIL PROTECTED] _ To unsubscribe: mail [EMAIL PROTECTED] with unsubscribe as the Subject archives at http://www.lazarus.freepascal.org/mailarchives
Re: [lazarus] Where can I find information about creating a new widget set?
Hi.
Peter, I suggest to add characters to your answers, it seems that 2
persons reply to this message but I couldn't check which one was you
answer...
Is this similar what Intraweb does in Delphi/Kylix?
I don't know about Intraweb, but I have seen similar frameworks on the net.
A completely new IDE can be an overkill for the project (at least for
now) imo. The component editors acceptable (like IW does that).
Actually, a new IDE or a new component Editor doesn't matter,
right know, because new components start by code ;-)
Thanks. ;-) What license is acceptable for you? Protective opensource
like GPL, LGPL or you prefer some other license?
I think you should use the same license as Lazarus does, but I think tha
LGPL is preferable.
Have you ever made components for Lazarus/Delphi before ?
I suggest you to start with the Browser component. I ussually start with
the TCustomPanel control as a base for a new control, and later add
properties, methods etc.
---
type
TMyBrowserPage = class(TPanel)
private
{ private declarations }
protected
{ protected declarations }
public
{ public declarations }
published
{ published declarations }
end;
---
First, start with your TMyBrowserPage control, just pretend you already
have it and you have one on you Browser form.
What properties should have, which of those properties and events are in
your object inspector, which ones are not but you can access by code ?
Make a list on a paper or an text editor.
I dont have Lazarus on my job pc right now,
later I will see how can I help.
I have done new visual controls for Delphi, and working on migrating to
Lazarus.
cheers.

Re: [lazarus] Some questions about TForm.Height
Hi. minus title bar height. Actually, in Lazarus TForm.Height is equal to TForm.ClientHeight in Delphi. The CLX (QT) form in delphi had a similar problem, I need it to simulate MDI forms with independent windows/forms, and need it to known the height of title bar... So, ones more - I can't find any info about that. This problem is very If it's not posible to calculate a title bar*s height in GNU/Linux, due to the different windows managers, why don't CREATE YOUR OWN TITLE BAR WITH YOUR OWN HEIGHT ? Let me explain, if is possible to create not title forms in GNU/Linux windows managers, then a workaround could be to create a form with no titlebar, and then emulate your own titlebar with your own custom close, minimize, maximize (zoom) buttons, where you can obtain the height of the bar... *Best regards, Alexey.* Cheers.

[lazarus] TRadioGroup and TStringList Error
Hi, I just downloaded lazarus 2.0 version for windoze, but when I try to add a TRadioGroup to a form and add some items and edit them on the TString Editor, it doesn't work. 1. What version of FPC (windowze) should I download ? 2. What version of Lazarus (windowze) should I download ? 3. Is it a TRadioGroup error or TString error ? I also read somewhere in lazarus page that TStrings descendant where not finished. (Like TMemoStrings for TMemo component) 4. I HAVE MADE some customs components for delphi, in fact I MADE A NEW TStrings descendant FROM THE GROUD, that uses 2 byte characters instead of 1 byte ASCII character, something like a TUnicodeStringList, including it's own property editor. So does anyone knows if TStringList isn't finished ?
