防止窗口重绘
是否可以防止窗口自动重绘？我希望它仅在我发出queue_draw()时重绘。
说明： 我需要这个，因为我正在使用工业图形的第 3 方商业库，我可以告诉它何时重绘，而且当 X 告诉它时它也会重绘，并且不可能阻止这种情况。因此，由于应用程序特定的要求，我需要防止这种情况发生，并仅在我告诉它时才重绘。
is it possible to prevent automatic redrawing of window? I want it to redraw only when I issue queue_draw().
Explanation:
I need this because I'm using a 3rd party commercial library for industrial graphics which I can tell when to redraw, but also it redraws when X tells it to and it is not possible to prevent that. Therefore, I need to prevent that because of an app-specific requirements and make it redraw only when I tell it to.

嗯，有什么意义呢？如果你不让它自动重绘，你将无法最小化/最大化窗口，将其从后台移动到前台......如果这些动作永远不会发生，那么你的窗口只有在以下情况下才被重绘：你调用queue_draw。只需在
expose-event处理程序中添加一些跟踪代码，您就会看到它。所以我认为你正在为错误的问题寻找错误的解决方案。
编辑：
所以你需要的可能是 GTK_APP_PAINTABLE 旗帜。
Well, what's the point? If you don't make it redraw automatically, you'll be unable to minimize/maximize the window, move it from the background to the foreground... And if these are actions that never happen, then your windows is already redrawn only when you call queue_draw. Just add some trace code in the
expose-eventhandler, and you'll see it.So I think your're looking to at the wrong solution for the wrong problem.
Edit:
so what you need may be the GTK_APP_PAINTABLE flag.
