A window that is a child of another window (i.e. probably this would be embedded within it) will have a parent. But any free-floating top-level window may have no parent (other than the window manager) so it's parent is NULL. > How could I get the parent window? A number of possibilities exist: - (the easy but hackish way) Make a global pointer to your master window that all the subsidiary windows can utilise. - (bit harder) make all your subsidiary windows based on a subclassed window that has a member function you can set that contains a reference to the master window. - and so on...
