Hi Mili!
1. When program start, there are 4 errors occor.=20
2. When you click the button on the window, the program crash!!!=20
Sorry, I can't help you. But here are my thoughts:
First of all it doesn't crash on my system.
One reason for the crash might be the lack of a cdecl after the callback
functions. But I don't think that this is the reason.
I've debuged it using gdb (or kdbg). The first error is created in line
275 (gtk_tree_view_column_add_attribute) but it's a bit suspect for me.
An other thing I've noticed is that you call gtk_init two times, in the
unit and in the app.
I'm not famillar with classes in pascal - but why do you want to put all
this code into a class? As far as I can read your code you'd linke to
combine several widgets to a class. I think there are better ways. I
once tried this in cpp but I failed (because of c++) Why don't you
create your own widget? Have a look at the tutorial at gtk.org. I think
this might be easier.
Ciao,
Olaf
