Hi,
I have written a program pretty much by re-adjusting the scribble
example from the GTK Tutorial, instead of creating my own PixMap in
the configure_event I called the following function which creates a
pixmap from file:
GdkPixmap* gdk_pixmap_new_from_file( const char *filename )
{
GdkPixbuf *pixbuf;
GdkPixmap *pixmap;
pixbuf = gdk_pixbuf_new_from_file( filename,NULL);
if (!pixbuf)
{
g_print( "Could not load `%s'!\n", filename );
return NULL;
}
gdk_pixbuf_render_pixmap_and_mask( pixbuf, &pixmap, NULL, 1 );
gdk_pixbuf_unref( pixbuf );
return pixmap;
}
I have this function called everytime expose_event is called because
the file that will get displayed in the drawing area keeps getting
updated by another program.
As the program runs and I move the mouse around the screen making
marks my CPU activity jumps dramatically and the virtual memory
occupied by the X-Window seems to be increasing on like an exponential
level.
I am wondering if maybe there is a call that can free up some of the
space as I recall the gdk_pixmap_new_from_file in the expose_event
callback. Or some other solution to mitigate this problem
thanks a lot,
Michal
