From my limited experience, either all or none :-) To a much greater extent than unix-based systems they rely on having smart terminals to do all the interactive stuff, and while waiting for something to happen sit there in a halted state (on a test system here, I see a something happen every couple of minutes spinning for a couple of thousand cycles). There's not very much difference between a 3270 terminal (and its equivalents from other manufacturers) and a classic web page with embedded forms: stuff gets sent to the terminal, the user fills fields in, changed areas get sent back. All of the frontend stuff can be wrapped in the same sort of GUI as a web browser gets, in fact IBM seem to have moved seamlessly to browsers rather than their classic terminals. It appears than many mainframe people make a virtue of the backends being written in assembler, for efficiency and- these days- geek cred. And up until around 2000, that assembler was pretty limited, e.g. all addressing was based on 12-bit offsets. These days a mainframe can run Linux, X11 and so on, but it's not what they were designed for and probably isn't the best way of using its specialised talents. -- Mark Morgan Lloyd markMLl .AT. telemetry.co .DOT. uk [Opinions above are the author's, not those of his employers or colleagues] -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus

On 20 March 2012 16:37, Frank Church vfclists@... wrote: Is it possible to drag and drop a web browser URL into a Lazarus app? Are there some controls with that facility? In fpGUI is is handled just like any other DND action. Simply register what mime-type the drop target must look out for. It will then happile accept a drop action if such a mime-type is supplied. Simple and easy to use, and works on all platforms. Lazarus's drag-n-drop is based on the very limited Delphi / Windows DND, so is mainly build for in-app drag-n-drop, and not able to accept external drag-n-drop actions. Normally (in Delphi) you would have to revert to Windows API calls to get better DND support. I remember seeing them (the Lazarus team) extending the default limited DND a bit to support dropping files on a LCL app, but that is a far cry from complete DND support. Out of interest, I ran the DND Demo of fpGUI, which shows what mime-types the source of a DND action is willing to supply. I dragged the URL from the Chrome web browser and dropped in onto the Text Edit field. Below that is the complete list of mime-types (8 in total) that Chrome was willing to supply the data in.

[Lazarus] Conditional compilation depending on Lazarus version?
Hi list,
I'm sure I must be missing something.
I want to compile some grid drawing stuff depending on whether a grid
bug has been fixed - i.e. I want to do something like this:
Had a look here:
http://wiki.lazarus.freepascal.org/IDE_Macros_in_paths_and_filenames
... but that only seems to specify support for FPC version, not Lazarus
version.
Ideally, I'd be looking at something like:
{$IF LAZARUSREVISION=36180}
// Note: normally, grid DefaultDrawing property must be off to avoid
duplicate drawing
// This will result in duplicate drawing but should work.
DefaultDrawing:=true;
{$ENDIF}
Is something like this possible, or is there an easier way of doing things?
I realize that the code above will be compiled by FPC, not Lazarus;
perhaps it is possible to set an environment variable LAZARUSREVISION
and/or LAZARUSVERSION and get these into FPC macros in some way?
Thanks,
Reinier

The revision is not possible (when using development versions you should
try to use the latest revision), but for version you can use the unit
LCLVersion. Just add it to the uses clause and then you can use e.g.:
{$if lcl_fullversion=93100}
// code that should work with 0.9.31 or newer
{$endif}
Just take a look at the unit to see which constants are supported (Note:
it makes use of the feature that constants can be used in compiler
conditionals)

From my limited experience, either all or none :-) To a much greater extent than unix-based systems they rely on having smart terminals to do all the interactive stuff, and while waiting for something to happen sit there in a halted state (on a test system here, I see a something happen every couple of minutes spinning for a couple of thousand cycles). That's why I ask - the client-server protocol doesn't deserve a GUI on the mainframe. I also assume that the protocol restricts the graphics capabilities, if there are any. There's not very much difference between a 3270 terminal (and its equivalents from other manufacturers) and a classic web page with embedded forms: stuff gets sent to the terminal, the user fills fields in, changed areas get sent back. All of the frontend stuff can be wrapped in the same sort of GUI as a web browser gets, in fact IBM seem to have moved seamlessly to browsers rather than their classic terminals. IMO every client type requires a different protocol, and specific preparation of the data to be sent to the terminals. Doesn't this require an dedicated widgetset in the LCL, for every client type? This in turn would require to compile a Lazarus application separately, for all supported client types (widgetsets). Otherwise another layer between the (then abstract) LCL components and their transfer to specific client types had to be implemented in the LCL.

Simple and easy to use, and works on all platforms. Lazarus's drag-n-drop is based on the very limited Delphi / Windows DND, so is mainly build for in-app drag-n-drop, and not able to accept external drag-n-drop actions. Normally (in Delphi) you would have to revert to Windows API calls to get better DND support. I remember seeing them (the Lazarus team) extending the default limited DND a bit to support dropping files on a LCL app, but that is a far cry from complete DND support.

Will this be fixed before the 1.0 release? Most OS's these days can and do use mime-types (just like the whole internet does) for DND. But obviously each OS/platform has a different way in which they transfer data between processes (I guess this is what you meant by like OLE-DragDrop). Anyway, fpGUI uses mime-types for DND, for in-app and cross-process DND. Under Windows, I still have support for the older-style DND (eg: where data types are registered as STRING or WIDESTRING like the clipboard etc). In the case of fpGUI under Windows, I simply map those older data types to similar mime-types automatically. X11 uses mime-types as-is (so no mapping or trickery required under X11). Mac OS X also has mime-type DND support. What's nice about X11's DND support is that no data is generated or transferred until it is actually known that the drop target accepted the drop. Windows unfortunately is not that clever and generates the data resources when the DND action starts at the source, not when the drop target accepts the drop. So Windows is a bit waist-full with resources (what's new). -- Regards, - Graeme - ___ fpGUI - a cross-platform Free Pascal GUI toolkit http://fpgui.sourceforge.net -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus

Great, thanks, that works!
At that point if there's an ./ide/revision.inc file containing
// Created by Svn2RevisionInc
const RevisionStr = '35880M';
can it be included into a unit to make it visible at compile time?
And is there a way of getting $i to do something intelligent if the file
it's looking for doesn't exist?

From my limited experience, either all or none :-) To a much greater extent than unix-based systems they rely on having smart terminals to do all the interactive stuff, and while waiting for something to happen sit there in a halted state (on a test system here, I see a something happen every couple of minutes spinning for a couple of thousand cycles). That's why I ask - the client-server protocol doesn't deserve a GUI on the mainframe. I also assume that the protocol restricts the graphics capabilities, if there are any. In any event: in the current case all I'm doing is putting together a couple of developer-oriented programs that run on PCs. There's not very much difference between a 3270 terminal (and its equivalents from other manufacturers) and a classic web page with embedded forms: stuff gets sent to the terminal, the user fills fields in, changed areas get sent back. All of the frontend stuff can be wrapped in the same sort of GUI as a web browser gets, in fact IBM seem to have moved seamlessly to browsers rather than their classic terminals. IMO every client type requires a different protocol, and specific preparation of the data to be sent to the terminals. Doesn't this require an dedicated widgetset in the LCL, for every client type? This in turn would require to compile a Lazarus application separately, for all supported client types (widgetsets). Otherwise another layer between the (then abstract) LCL components and their transfer to specific client types had to be implemented in the LCL. I think we're at cross-purposes. As I said above, I'm currently not trying to have anything that runs on a mainframe, and neither am I trying to implement a general-purpose terminal emulator. /If/ there were an FPC port to run on a mainframe, it would see something roughly comparable to stdin/stdout (possibly using EBCDIC- let's not go there). /If/ I were trying to write a terminal emulator, then of course it would need to talk 3270 (possibly with SNA, or alternatively using the equivalent Burroughs etc. protocols). I'm not trying to do either of those things, but if I were then the clientside stuff could obviously be wrapped in a GUI in exactly the same way that HTTP/HTML is wrapped in a GUI or in the same way that AlphaWindows assumed a smart terminal with a GUI. -- Mark Morgan Lloyd markMLl .AT. telemetry.co .DOT. uk [Opinions above are the author's, not those of his employers or colleagues] -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus

I was looking at these versions a few days ago, because I've got one
project which I'm trying to keep compatible with GTK v1. Being to base
coding decisions relating to e.g. Synedit capabilities on Lazarus rather
than FPC version, without having to go to RTTI, is obviously a major
advantage.

[Lazarus] Ignoring all warnings from an entire directory
Is that possible? Something like *-vf$(LazarusDir)/components* to supress warnings from outside my project. It's not about ignore some kinds of warnings (like *-vm4055*), but ignore all warnings in files inside a directory. -- Atenciosamente, Alexsander da Rosa http://rednaxel.com -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus
[Lazarus] Threads
Hi folks. Wen launching a thread, the process responsible for the thread object creation and the call to TThread.Start and the thread EXECUTE procedure, run in parallel. That's why the SYNCHRONIZE procedure exists and that the developer has to pay attention to not share code between threads. So far, so good. Now imagine that the EXECUTE procedure of a thread creates a useful object (TMyObject) with properties and methods. This thread is launched half a dozen times to process half a dozen simultaneous operations. My question is: How the properties and methods of the TMyObject created in every launched thread are they managed from one thread to another. As far as the data segment is concerned, no problem, I guess that every instance of the TMyObject has its own data in its thread address space: no mix. But what about the code and the local methods stack: will it be shared ? And if answer is yes, to what should I take care ? The question is far from trivial: I try to keep the EXECUTE procedure as small as possible and spread the code and data over a number of specialized units avoiding to load the EXECUTE procedure stack with heavy data ans structures. I apologize if my question doesn't sound very clear, but it's not even clear in my mind :-[ Antonio. -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus

It's not about ignore some kinds of warnings (like -vm4055 ), but ignore
all warnings in files inside a directory.
If it is about the components in the Lazarus directory: IMO all
warnings/notes should be fixed. Either by code or by {%H-}. Any help is
welcome.
AFAIK there is no command line parameter to omit messages for directories.

Re: [Lazarus] Threads
Besides what the other said a very basic comment. The location where an object is defined (i.e. within a TThread enabled unit) or who created it (the main line code or the thread code) does not matter. The Concept of classes, objects and instances is a matter of memory allocation and pointers and not a concept of program flow. same is absolutely independent. You can use one instance of a class in one thread and another one in another thread. You can create an instance in one thread and call its procedures and properties by another one. (BTW this results in the fact that its very hard to define something like Thread-safe for a class). In fact you need to look exactly how the program flow of each thread is before deciding what code needs to be protected regarding mutual accesses by threads. Just looking at the objects does not help much, Looking at the point where an object is created does not help at all. -Michael -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus

Should I fix them on trunk or may I fix them on 0.9.30.4 release (that I am
using)? It's easier to fix in the version I use on a daily basis, to fix in
the trunk I would have to work only at weekends.

Re: [Lazarus] Conditional compilation depending on Lazarus version?
2012/3/22 Mark Morgan Lloyd markmll.laza...@telemetry.co.uk:
At that point if there's an ./ide/revision.inc file containing
// Created by Svn2RevisionInc
const RevisionStr = '35880M';
can it be included into a unit to make it visible at compile time?
You can add $(LazarusDir)\ide to the include paths of the project.
Then this works:
{$I revision.inc}
const
revIntroducedNewFeature = '5';
begin
{$IF (RevisionStr = revIntroducedNewFeature)}
UseNewFeature;
{$ENDIF}
end;
