MFC CEditView重绘两次 [英] MFC CEditView redraws twice

问题描述

我有一个MFC选项卡式MDI应用程序，其中选项卡式子窗口类型是CEditView，CRichEditView和CView。我注意到当我在它们之间切换时（单击选项卡的顶部使该窗口成为活动窗口），它们按预期重新绘制客户区，但CEditView窗口闪烁......我可以看到它们重新绘制了两次（至少）出于某种原因。 CView和CRichEditView窗口只重绘一次。



即使CEditView窗口已经是活动选项卡，如果我单击窗口顶部，它会重新绘制两次。 ..闪烁。



因为这个重绘/闪烁很烦人 - 有没有人知道它为什么会不止重绘一次？



Thx，

解决方案

好主意Nelek。



我把应用程序中的每个Invalidate和UpdateWindow都有一个断点...唉它没有点击任何一个。



似乎它没有被我的代码明确触发

I have a MFC tabbed MDI application in which the tabbed child window types are CEditView, CRichEditView and CView. I''ve noticed that when I switch between them (click the top of the tab to make that window the active window) they repaint the client area, as expected, but the CEditView windows flicker .. and I can see they are repainting twice (at least) for some reason. The CView and CRichEditView windows only repaint once.

Even if the CEditView window is already the active tab, if I click the top of the window, it gets redrawn twice ... with a flicker.

Since this redraw/flicker is annoying - does anyone have an idea why it would redraw more than once?

Thx,

解决方案

Good idea Nelek.

I put a breakpoint on every Invalidate and UpdateWindow in the app ... and alas it did not hit any of those.

It seems it is not being triggered by my code explicitly.
