Some documentation to access the interfaces directly is in the wiki: http://wiki.lazarus.freepascal.org/Accessing_the_Interfaces_directly But, as said, some recent changes were made. -- Felipe Monteiro de Carvalho _ To unsubscribe: mail [EMAIL PROTECTED] with unsubscribe as the Subject archives at http://www.lazarus.freepascal.org/mailarchives
[lazarus] accessing internal widgetset handle
Hi all, I'd like to create a gtk(2) app that has a non-rectangular form shape, using Lazarus of course. I know gtk(2) provides API for this purpose. The API requires a pointer to GTKWidget. But, I couldn't find any ways to get the widget pointer of Lazarus' form since Lazarus wraps the API very well inside LCL. Hints? TIA. BTW... which API should I use for this purpose, gtk or gdk? Both wrappers are provided in FPC/Lazarus and both provide similar API for the purpose. In term of Lazarus' LCL, what are the differences between both? -Bee- has Bee.ography at: http://beeography.wordpress.com _ To unsubscribe: mail [EMAIL PROTECTED] with unsubscribe as the Subject archives at http://www.lazarus.freepascal.org/mailarchives

Both gtk and gdk are available in the gtk interface. I don't know, which one you use for this. If you need the gtkwindow, then just type cast Form1.Handle: GtkWindow:=PGtkWindow(Form1.Handle); Beware, that this is an internal LCL gtk interface structure and can change in the future without warning. If you find out how to do it, it would be nice to write a small example and describe it on the wiki. Eventually this feature could be added to the LCL.

And it will. The right way to do it in laz 0.9.26 and up is: GtkWindow := PGtkWindget(SomeWincontrol.Reference.Ptr); This won't change. A Reference: TWSReference is the replacement for all handles used in the LCL. Unfortunately it is not yet implemented for TWincontrol, so for now you need to cast the handle.

Normally I'd tend to use gdk, but I'm not sure (it's been a whilesince I fiddled with that directly ...). You could look at some GTK/GDK docs and tutorials or ask on their mailing list.
