[lazarus] Polymorphism question
I would like to declare a polymorph class. The class has several
properties and it's the read and write specifiers that I want to be
virtual abstract. So derived classes override the read and write
specifiers. The problem however is that I get an EAbstractError. The
property is still considered to be abstract according to the compiler. So
what did I wrong? I have added an example below.
Is it perhaps not allowed to use this construct? What would then be the
best way?

unit MyTest;
{$mode objfpc}{$H+}

TCustomClass = class
private
//virtual mehods
function GetMyProperty: string; virtual; abstract;
procedure SetMyProperty(Value: string); virtual; abstract;
published
property MyProperty: string Read GetMyProperty Write SetMyProperty;
end;
TMyClass = class(TCustomClass)
private
FMyProperty: string;
function GetMyProperty: string; overload;
procedure SetMyProperty(Value: string); overload;

[lazarus] Repository access via the SVN protocol
Hi, Would whoever is running the Free Pascal / Lazarus repository consider enabling the SVN protocol as well. Currently only the HTTP protocol is enabled. (example: GCC has both protocols enabled at svn://gcc.gnu.org/svn/ or via http://gcc.gnu.org/svn/) I have also heard that using the HTTP protocol has a higher server overhead associated with it and is normally slower compared to the SVN protocol, though I know how handy it is via a firewall. The reason I'm asking: It seems that somewhere our ISP in South Africa is blocking or filtering something, which causes us not to be able to access the http://www.freepascal.org/svn repository. It is very frustrating to download huge nightly builds every day (7Mb for Lazarus and 20Mb for FPC). This also make it really difficult to help development on these projects and generate patch files, as the nightly builds do not contain the .svn directories. Every SubVersion server I could find using the SVN protocol seem to work fine, the same cannot be said for the HTTP protocol. I really hope, whoever is in charge of the repositories will consider this request.

If you use gtk (linux/MacOSX/FreeBSD) then maybe this works:
Create a lazarus.gtkrc file with the following content and put it into
lazarus directory where the 'lazarus' executable is:
style default
{
font = -*-lucida-medium-r-normal-*-10-*-*-*-*-*-iso8859-1

You can find the correct font name in the font selector of the environment

[lazarus] USB port in LAZARUS

In Linux I can send EPCL to Printer with this simple command: cat file.prn /dev/usb/lp0 where file.prn it contains the EPCL commands. But the problem is that I don't know how to read the status of the printer after the print of each card.

Furthermore, personally, I do not consider a program portable if it is written in a language which very few can understand. Althought a lot less popular then c, c++ and java, pascal is still reasonably popular, and is easy to learn. Very important software like Skype is written on Object Pascal. Mac OS 7 and below had a lot of Object Pascal code on them, and it's API was written fully in pascal. A modern language such as any of the .NET languages will meet the efficiency objective but portability remains an issue. This statement isn't true. .NET in general has performance much inferior to native pascal. Take a look at debian shootout comparison of Free Pascal and c#: http://shootout.alioth.debian.org/debian/benchmark.php?test=alllang=fpascallang2=csharp Free Pascal is more then 10 times faster and uses 10 times less memory. Yes, benchmarks are all flawed, but a huge difference like this can point at .NET performance flaws. Also take a look at this article: http://www.microsoft-watch.com/article2/0,1995,1820607,00.asp Specially the part: quoteEverything in Longhorn was supposed to be written in C# and to be managed code. But managed code was going to require machines that weren't going to be available for five years or more. So now Microsoft is rewriting everything in Longhorn, the developer says. Developers claim that the Windows team actually began rethinking Microsoft's .Net Framework and managed code promises last summer, around the time of the infamous Longhorn Reset. (The Longhorn Reset is shorthand for Microsoft's decision to axe certain Longhorn features, most notably WinFS, in order to be able to commit to a 2006 ship date.) end quote While I do have the Visual Studio .NET and I am happy with it, I understand that not everybody has it and it is not cheap. I bet that the price of buying VS will be a much bigger blocker then people needing to write pascal code. Pascal is considered easy to learn, and still used a lot in basic programming courses. It will however, limit us to Pascal which is not really a modern language. For those of you who are in favor of using Lazarus, can you assure the rest of us that Pascal has been modernized? When I talk to developers of other languages they all think Pascal is that non-object oriented thing from early 1980s and that it did not change people need to know that Object Pascal is the real industry used pascal. One prove that Pascal is evolving still today is the talks on fpc mailling lists about the inclusion of templates (generics). -- Felipe Monteiro de Carvalho _ To unsubscribe: mail [EMAIL PROTECTED] with unsubscribe as the Subject archives at http://www.lazarus.freepascal.org/mailarchives

Re: [lazarus] setColor part 3
Hi with current CVS setColor for tSpeedButton don't work DrawFrameControl can draw only rectangle with or without shadow, no other possibilities rest investigation under now i prepare patch for tSpeedButton Why use Frame3D instead of DrawFrameControl ? its simpler, and why one function for drawing for all components, (on other side is used only 3 times toolbutton, speedbutton and checkbutton) SpeedButton is draw near all without widget, Frame3D should be faster and identical on all platforms The buttons look should follow the users theme. They should not look the same on all platforms. With Frame3D we loose the theme background of buttons. I commented this out and kept the old DrawFrameControl. Under tSpeedButton is no background (as I know), all is painting I have similar problem with tPanel and tHeader, but i will investigate in next time A button under gtk1 is an area, not just the frame. Some themes define a simple darkened area when presses, some some define whole images (e.g. round buttons). Maybe gtk2 has more possibilities for TSpeedButton. Interesting are there possibilities, which we can use in all OS, of course we can implement all myself, but we are limited by LCL API, for example now I can't change color of shadow (tButton have not thous properties) I think, that we should implement more flexible widgets, not so dependent from desired library (GTK, WIN, QT) I don't know exactly, but DrawFrameControl can't draw round frame, thats not issue, we have own paint function with caption and glyph, only frame left from widgets I don't know, what windows can do with DrawFrameControl, but under gtk it draws an area in a specific style. If this is a button style, and the theme defines an image, it paints it. If I want (as programmer) to one of buttons will be red, user should'n change it by change theme for tButton all depend from widgets, but for me in tSpeedButton all should be independent. (GTK has't two widgets) Gtk has less widgets, because the idea is combine them. A TGroupbox is a single widget under windows, while under gtk it needs two. For gtk it is pretty normal to put a 'listbox' into a menu. That's why you have more possibilties. A TSpeedButton that is used a button and that draws some rectangles, when all other widgets on the application have shaded round widgets looks very ugly.

On Fri, 3 Mar 2006, Matt Henley wrote: I belong to a mailing list for a defunt open source chemical process simulator (Sim42). Members of the list are now showing interest in restarting the effort. It was originally written in python which cause some speed issues. Several of the list members (including me) suggested freepascal and lazarus. The gentleman spearheading the effort sent the following and I would like to know what is the best way to respond. I do not know what features define a modern language and would like to know what points to bring up. My personal objective is not just to put out a simulator, but a fast and efficient simulator. Furthermore, personally, I do not consider a program portable if it is written in a language which very few can understand. A modern language such as any of the .NET languages will meet the efficiency objective but portability remains an issue. While I do have the Visual Studio .NET and I am happy with it, I understand that not everybody has it and it is not cheap. I looked at the Lazarus project and (at least at a first glance) it is indeed very Visual and will likely do the job. It will however, limit us to Pascal which is not really a modern language. For those of you who are in favor of using Lazarus, can you assure the rest of us that Pascal has been modernized? Most people out there probably think of Pascal as still being in the state it was in when Niklaus Wirth first designed it. Object Pascal to date is fully OOP, and misses nothing that C#, C++ or Java has: Interfaces, Exceptions, Classes: you name it, Object Pascal has it.

But if you want a 'red' button, then you want a custom drawn button, not a TButton. If 'red' buttons are needed that often, then we should add a TCustomDrawnButton (or whatever name fits) with properties like Color, TSpeedButton ?

I mean we're getting a lot of buttons this way, with mostly redundant (duplicate) code ... :-/ Micha _ To unsubscribe: mail [EMAIL PROTECTED] with unsubscribe as the Subject archives at http://www.lazarus.freepascal.org/mailarchives
