高DPI屏幕上的MFC cdialogbar绘图问题 [英] MFC cdialogbar drawing issue on high DPI screen

问题描述

我创建了一个MFC SDI应用程序，并添加了CDialogBar以设置为主工具栏，就像我在附加的屏幕截图中看到的那样。它适用于Windows平板电脑设备的每个Windows操作系统（Xp，7,8,8.1,10），只有Microsoft Surface。



请看这个截图。 CDialogBar菜单被切断。我不知道为什么会这样。绘图问题始终只发生在具有高分辨率和高DPI屏幕的Microsoft Surface 3上，并且在任何其他平板电脑上都能正常工作。这是一个非常奇怪的问题所以我拖动工具栏（CDialogBar）并在任何地方放下，然后工具栏被重新绘制得很清楚。所以..通过这个问题，我确信这是重新绘制的问题。是否有任何绘图功能重绘该区域？



我附加了最小化的源代码来表示绘图问题。

我的尝试：



要解决此问题，我一直在尝试将 DPI Awareness 属性设置为None，但图形界面并不好，而且它们都被拉伸了。我真的不喜欢这个解决方案，我必须找到其他解决方案而不将 DPI Awareness 设置为None。

解决方案

强制执行重绘您可以使用 InvalidaRect 。

I have a MFC SDI application created and added CDialogBar to set as main toolbar as you look in the screenshot I attached. It works well on every windows os(Xp, 7, 8, 8.1, 10) of windows tablet devices except only Microsoft Surface.

Please look at this screenshot. the CDialogBar menu is cut off. I don't know reason why this happens. The drawing issue always only occurs on Microsoft Surface 3 which has high resolution and high DPI screen and it works good on any other tablet. This is very strange issue so I dragged toolbar(CDialogBar) and dropped down on any place then the toolbar was re-painted clearly. So.. through this issue, I am sure that this is re-drawing issue. Is there any drawing function to redraw that area?

I am attaching my minimized source code to represent drawing issue.

Please help me. Thanks

Operating System: Windows 10

Tool: Visual Studio 2015 Update 3
DPI rate: 150%

What I have tried:

To resolve this issue, I have been trying to set DPI Awareness property to None, but the graphics Interface was not good and they were all stretched. I really don't like this solution, I have to find other solution without setting DPI Awareness to "None".

解决方案

To enforce a redraw you can use InvalidaRect.
