[lazarus] How does RegisterWSComponent work?
Hi, when I comment the command RegisterWSComponent(TCustomBitBtn, TWin32WSBitBtn); in file win32wsbuttons.pp in win32 interface, Lazarus crashes. How is then possible that GTK2 interface is working (I suppose it is working, did not try) and has this command commented out?

But you're right, if I get there and squeeze out the last bytes for embedded systems I'll make it publicly available.

As you can imagine, on embedded nano-computers every single byte has to be checked if it does something useful, the other ones have to go home. ;) (not compactsysutils ones, things like database access , sessions, cookies functions). Maybe you thought I was going to put compactsysutils functions in a dll - I didn't mean that. But actually it's an interesting thought - having some of the fpc RTL in a dll. Or, maybe I misinterpreted your misinterpretation :) I think from reading the message from Florian Klämpfl with the subject dyn. linked lazarus the door to dynamicylly linked basics like RTL is pushed open with fpc 2.1.1. That's a big step forward in general - good work, Florian and others involved! For small CPUs it is not sufficient, because wether a byte is linked in statically or sits in a dynamic library - it has to be loaded anyways. One way I started thinking about was to use non standard X-Server (X.org or XFree86) but something like NanoX or similar. Unfortunately none of the ones I know run on FreeBSD ...

Re: [lazarus] How does RegisterWSComponent work?
gtk has many similar problems. I tried lazarus and fpc snapshot 20060110 on kanotix (konoppix clone / KDE), ubuntu (GNOME), kubuntu (KDE) and suse 10.0 (KDE and GNOME). Exept on suse / GNOME many items including the text inside the editor disappears from time to time. On suse / GNOME speed buttons disappear when the mouse is moved over that part of panel and sometimes labels disappear, when the mouse is moved over them. The IDE crashes from time to time.

Yes, this is my favourite. As you can imagine, on embedded nano-computers every single byte has to be checked if it does something useful, the other ones have to go home. ;) Do you think the PStrList will be useful, and some other fake (byte friendly) classes (objects) in CompactUtils? I know pure arrays and and simple variables without any objects at all, will save bytes, but hey wouldn't it be nice to have some of object oriented programming without the cost of bytes? Yes in your case embedded programming will not benefit from DLL programming of course - in fact dll programming is more inefficient than static linking because with static linking you don't have to load the entire DLL with wasted functions in it. I'm not one of those dudes who is anal about having Exe's small - it's just a matter of having a leading advantage of being able to upload a nice small 30kb powerful CGI program and of course being able to work with embedded systems. That is one advantage with FPC is being able to work with embedded systems, over say python or perl. I'm sure people would love working with Pascal rather than C for embedded systems, but in order for Pascal to have a chance in embedded systems we must have projects like this compactutils and system.ppu replacements, otherwise people will have to resort to C. Because the big 30kb hello world exe and the 90kb hello world exe with sysutils in the uses clause is not good for embedded systems. _ To unsubscribe: mail [EMAIL PROTECTED] with unsubscribe as the Subject archives at http://www.lazarus.freepascal.org/mailarchives

[lazarus] Lazarus on MacOSX
Improvements for Lazarus on MacOSX: - TSynEdit bold/italic bug has been fixed. It was a endian typecast bug. - The IDE now uses the -w flag for 'make' to force Entering/Leaving directory messages. This fixes the file not found errors, when working on the IDE under Mac. So, the best tool to work under MacOSX is Lazarus. - The carbon interface, a native LCL widgetset for the MacOS (aqua look, ..) now includes the unit fpcmacosall.pas. That means you no longer need to install the UInterfaces. - carbon interface is now comilable under Linux/FreeBSD. This means compile tests for target carbon can be made on other platforms. Just set the compiler option LCL Widget Type to carbon and compile. - carbon interface: Mouse events (Down, Up, Move, Click, Double Click, Triple Click, Quad Click, Wheel) now work. - Graphical applications under MacOSX require a special directory structure with some resource files. Otherwise the application can not be focused and has no menu. There is now a small tool to create these directories (components/macfiles/examples/createmacapplication.lpi). See wiki links below. - There are some wiki pages describing how to install Lazarus on Mac and how to create native carbon applications: http://wiki.lazarus.freepascal.org/index.php/Carbon_Interface - For those interesting in helping programming the carbon interface, there is a wiki page: http://wiki.lazarus.freepascal.org/index.php/Carbon_interface_internals - A demonstration, that the carbon interface is already usable, is: The Lazarus OpenGLControl already supports the carbon interface with AGL. This means TForm, TButton and TOpenGLControl are the first three working carbon controls.

[lazarus] compare
I have just found your product Lazarus. I have used Delphi several years ago, but stopped using it. The cost of the advanced features such as client server was the reason. Is Lazarus something that can be used or will it have limitations? Jim
