C++ (Cpp) WM_cursor_modal Examples

Example #1

File: interface_ops.c Project: mik0001/Blender

/* Modal Operator init */
static int eyedropper_invoke(bContext *C, wmOperator *op, wmEvent *UNUSED(event))
{
	/* init */
	if (eyedropper_init(C, op)) {
		WM_cursor_modal(CTX_wm_window(C), BC_EYEDROPPER_CURSOR);

		/* add temp handler */
		WM_event_add_modal_handler(C, op);
		
		return OPERATOR_RUNNING_MODAL;
	} else {
		eyedropper_exit(C, op);
		return OPERATOR_CANCELLED;
	}
}

Example #2

File: wm_cursors.c Project: 244xiao/blender

/* to allow usage all over, we do entire WM */
void WM_cursor_wait(bool val)
{
	if (!G.background) {
		wmWindowManager *wm = G.main->wm.first;
		wmWindow *win = wm ? wm->windows.first : NULL;
		
		for (; win; win = win->next) {
			if (val) {
				WM_cursor_modal(win, BC_WAITCURSOR);
			}
			else {
				WM_cursor_restore(win);
			}
		}
	}
}

Example #3
