通过关闭WS_CLIPCHILDREN减少闪烁 [英] Reduce flickering By Turning off WS_CLIPCHILDREN

问题描述

我已经开发了一个Windows应用程序，该应用程序的界面有多个文本框，所有文本框都放置在一个面板中(该面板具有背景图像).

I have developed a windows application whose interface has a multiple text boxes and all of them are placed in one panel (the panel have a background image).

每次加载面板时，带有这些文本框的窗口都会闪烁.

Whenever the panel is being loaded, the window(with these textboxes) is flickering.

我阅读了很多建议以最大程度地减少这种闪烁， 以下是建议的解决方案之一，

I read a lot of suggestions to minimize this flickering, One of the suggested solutions was the following,

SetStyle(ControlStyles.UserPaint, true);
SetStyle(ControlStyles.AllPaintingInWmPaint, true); 
SetStyle(ControlStyles.DoubleBuffer, true);

但这对我不起作用

我读到有关使用以下代码关闭WS_CLIPCHILDREN的信息:

I read about turning off the WS_CLIPCHILDREN using this code:

protected override CreateParams CreateParams {
  get {
    var parms = base.CreateParams;
    parms.Style &= ~0x02000000;  // Turn off WS_CLIPCHILDREN
    return parms;
  }
}

此代码可帮助遇到相同问题的某些人.因此，我想使用它，但我真的不知道将其粘贴到哪里，我的意思是，我读到它应该粘贴在 UserControl的代码中，而不是粘贴在表单中.我不知道该怎么做，我使用的所有控件都不是自定义控件.

This code help some people who faced the same problem. So I want to use it but I really don't know where to paste it, I mean, I read that it should be pasted not in the form, but in the the UserControl's code. I don't know how to do that, all the controls that i used is not a custom controls.

推荐答案

您也可以考虑打开WS_EX_COMPOSITED样式，在某些情况下可能会有所帮助:

You might consider turning on WS_EX_COMPOSITED style also, it may help in some cases:

parms.ExStyle |= 0x02000000; //WS_EX_COMPOSITED
