Cursors, too, have been a constant source of pleasure. The main difficulty
is that a GdkWindow inherits a cursor if the programmer sets a new cursor
- for the parent. To prevent this from doing too much harm, I use idle time
- to set the cursor over and over again, starting from the toplevel windows
- and ending with the youngest generation (speaking of parent and child windows).
+ for the parent. To prevent this from doing too much harm, SetCursor calls
+ GTKUpdateCursor, which will recursively re-set the cursors of all child windows.
Also don't forget that cursors (like much else) are connected to GdkWindows,
not GtkWidgets and that the "window" field of a GtkWidget might very well
point to the GdkWindow of the parent widget (-> "window-less widget") and
that the two obviously have very different meanings.
