Hello,
it seem using an application as a PG_APP_TOOLBAR, which load a theme
with only some specifications for button, and another application as a
PG_APP_NORMAL, with a "kind of scrolled list" of PG_WIDGET_FLATBUTTON
crash the pgserver (at least on Linux/x86/SDL, don't have try other for
the moment).
You can test this with the attached files :
1. compile the two files test_sb.c and test2_sb.c
2. compile the theme temp.th
3. start your server
4. start test_sb and test2_sb
5. move your mouse on the toolbar (bottom of the window)
It's crash with :
X Error of failed request: BadValue (integer parameter out of range for operation)
Major opcode of failed request: 146 (MIT-SHM)
Minor opcode of failed request: 3 (X_ShmPutImage)
Value in failed request: 0xffe7
Serial number of failed request: 94
If I change one of the following thing the server don't crash anymore :
- don't load the theme
- remove the object button from the theme and put something else (for
example a default font)
- don't have two calls to pgRegisterApp() (one application whos create
the toolbar and the list of flatbuttons.
- remove the scroll
- have a pgserver window big enough to have nothing to scroll
Can I make something to have no more crash ?
Thanks in advance.
Olivier
