Example #1

	var cmd int32
	if visible {
		cmd = win.SW_SHOW
	} else {

	// 3. 主消息循环
	var msg win.MSG
	msg.Message = win.WM_QUIT + 1 // 让它不等于 win.WM_QUIT

Example #3

Example #5

File: cody.go Project: CodyGuo/Go-Cody

// 该函数将焦点切换指定的窗口，并将其带到前台。
func (wb *WindowBase) SwitchToThisWindow(switchto bool) {
	win.ShowWindow(wb.hWnd, win.SW_RESTORE)

	// message handling
	hwnd := win.HWND(unsafe.Pointer(s.GetHwnd()))
	win.ShowWindow(hwnd, win.SW_SHOW)
	win.UpdateWindow(hwnd)
