You can derive the Window parameter from an object with FL_ObjWin().
Note: There's a small glitch here. If you want to set the cursor to
a clock on a form that has child Windows, such as Canvas objects or
TabFolder objects, you need to descend the Window tree. Here are two
little routines I cobbled up recently to do this:
void spl_set_cursor( FL_FORM *form, int cursor )
{
Window w = form->window;
Window root;
Window parent;
Window *children;
int nchildren;
XQueryTree( fl_get_display(), w, &root, &parent, &children,
&nchildren );
if ( nchildren ) {
while ( --nchildren > 0 )
fl_set_cursor( children[nchildren], cursor );
XFree( children );
}
fl_set_cursor( w, cursor );
fl_check_forms();
}
void spl_reset_cursor( FL_FORM *form )
{
Window w = form->window;
Window root;
Window parent;
Window *children;
int nchildren;
XQueryTree( fl_get_display(), w, &root, &parent, &children,
&nchildren );
if ( nchildren ) {
while ( --nchildren > 0 )
fl_reset_cursor( children[nchildren] );
XFree( children );
}
fl_reset_cursor( w );
fl_check_forms();
}
