Hi, I'm adding a xpm into a button but i don't really understand how to
use the "mask" parameter.
The Reference Manual says:
"GdkPixmap* gdk_pixmap_create_from_xpm (GdkWindow *window,
GdkBitmap **mask,
GdkColor
*transparent_color,
const gchar *filename);
Create a pixmap from a XPM file:
mask�: a pointer to a place to store a bitmap representing
the transparency mask of the XPM file. Can be NULL, in which case
transparency will be ignored."
But I haven't found any example where the parameter "mask" is really
used. I mean, in the examples i've found it will be the same to put a
NULL instead.
Can anyone show me an example using another value for "mask"??
Thanks in advance
Ignacio Nodal
