GtkImage widget displaying pixmap with a mask.
A GdkPixmap is a server-side image buffer in the pixel format of the
current display. The GtkImage does not assume a reference to the
pixmap or mask; you still need to unref them if you own references.
GtkImage will add its own reference rather than adopting yours.gtkImageNewFromPixmap(pixmap = NULL, mask = NULL, show = TRUE)pixmapGdkPixmap, or NULL. [ allow-none ]maskGdkBitmap, or NULL. [ allow-none ]
