使用WinXp通用控件时编辑控件背景色的奇怪行为 [英] Strange behaviour of edit control background color when using WinXp common controls

问题描述

我遇到了一个奇怪的问题(嗯，至少我发现它很奇怪=)).我正在编写自己的GUI库，该库是Windows api的包装(是的，我知道WTL和类似MFC =的框架).在当前阶段，我已经以这种方式封装了通用控件:例如，Edit类由一个简单窗口和一个位于其上方的标准编辑窗口(MainWindow-> GhostWindow-> EditBox)组成.例如，这就是我可以如何在编辑类本身内部更改编辑的背景颜色的方法:

myedit->SetBkColor ( RGB ( 0, 0, 0 ) );

它运行良好，直到我调用InitCommonControlsEx并将清单文件附加到我的程序中为止.完成此操作后，我的编辑仅在具有焦点时才能够更改颜色.老实说，我对为什么这样的行为以及我做错了事没有全面的想法，所以我将不胜感激.

谢谢，#535.

解决方案

好吧，一切都比我想的容易得多.我太不专心=(当一个人不使用样式时，一根手杖使用:: SetBkColor(...)更改背景色，然后从WM_CTLCOLOR *返回画笔以更改边框颜色.现在，:: SetBkColor(...)对应于 focus 颜色，返回的画笔会更改背景颜色.

I am having a strange problem ( well, at least i find it strange =) ). I am writing my own GUI library, which is a wrapper around windows api (and yes, i am aware of WTL and frameworks like MFC =) ). At the current stage i have incapsulated common controls in such manner: for example, Edit class consists of a simple window and an standard edit window above it ( MainWindow -> GhostWindow -> EditBox ). That is how i can for example change a background colour of an edit inside an edit class itself:

myedit->SetBkColor ( RGB ( 0, 0, 0 ) );

And it worked fine, until i called InitCommonControlsEx and attached manifest file to my program. After doing this, my edits become capable of changing colours only when they have focus. To be honest, i don't have a comprehensive thoughts about why do the behave like this and what am i doing wrong, so i will appreciate any help.

Thank you, #535.

解决方案

Well, everything is much easier, than i thought. I was just too inattentive =( When one don't use styling, one cane use ::SetBkColor(...) to change background colour, and return a brush from WM_CTLCOLOR* to change a border colour. Things become different after enabling styling. Now ::SetBkColor(...) correspond to focus colour and returning brush changes background colour. Shame on me =(
