[desktop-discuss] use gdk api to replace X11 api

[Jedy Wang]

Hi all,

The following application starts up a ???Run Application" dialog. If I use
X11 api, the application works fine. But if I use gdk api, the dialog
can not be started. Does anyone know if there is something wrong with
the code? Thanks in advance.

BTW:
You can run 'cc [source] -g `pkg-config --cflags --libs gdk-2.0`' to
build the source.
