Marc - thanks for the reply - I have never used a patch file before, so after a little study (ie man patch) I used the following 1- saved all between <patch> to </patch> to textfile 'winapipatch' 2- placed patch file in /lazarus/lcl/interfaces/gtk directory 3- changed to same dir in shell
4- tried 'patch gtkwinapiwindow.pp winapipatch
kept getting errors at this point (probably something I have wrong)

So - I manually applied changes to orig file (cut/paste) and rebuilt All seems to be working fine now - really appreciated !

Could you let me know what I did wrong in applying the patch ?

Thanks

+ Strange patch. You have to increase the fuzz factor and deactivate space

+
+ patch -p0 -F4 -l -i diff.txt
+
+ Marc, how did you create it?

eehhh.... cvs diff -u gtkwinapiwindow.pp

and I pasted the output in my mail (thats probably where it went wrong)

+ I applied it to cvs.

OK

Marc

At the time I wrote LCLWinapiWidget I wasn't a gtk expert (and that's still the case :), so the code there is merely based on examples and some GTK internals (I used gtkedit ? as an example).

However looking at it now I can imagine your problem. I wrote a little patch based on dox, but couldn't test it. So I didn't commit it to cvs. If you aply the patch and it works, please let me know.

Marc

Strange patch. You have to increase the fuzz factor and deactivate space comparison:

patch -p0 -F4 -l -i diff.txt

Marc, how did you create it?

I'm not a patch expert either, but IMO it should work. Don't know what errors you get.

Is it possible to display forms contained in a library (lib***.so) ? I can use libraries for all non-graphical functions without problems, but fail with "Gtk-Warning **: gtk_type_create(): type 'LCLWinapiWidget already exists"

Any ideas on this ??

Thanks
