纯Win32 C开发中的视觉样式 [英] Visual Styling in pure win32 c development

问题描述

您好，亲爱的Codeproject读者和开发人员，

我想提出一个问题，因为我想发展自己的技能和知识，我希望从Windows 2000开始就使用Microsoft提供的有关Visual Style的一些信息，以在按钮，边框等上添加一些整洁的效果.

当我使用CreateWindow创建一个不使用MS Shell Dlg2替代字体的窗口时，如何在整个应用范围内添加该应用?

当我在窗口上创建子控件并激活视觉样式时，我得到了一个丑陋的白色边框(应该是透明的)，我尝试使用WM_CTLCOLORBTN，WM_CTLCOLOREDIT进行严格的方式，但是我认为唯一的方法是对每个子类进行子类化子控件(使用WM_NCPAINT/WM_NCCALCSIZE)并自己绘制视觉样式，这是要走的路吗?


请，如果您需要一些我可以提供的示例代码，我只是不想让该问题向代码中发送垃圾邮件，这会使阅读起来变得更困难.

Hello dear fellow Codeproject readers and developers,

I got a question, as I like to develope my skills and knowledge I would like some input about Visual Style from Microsoft used since Windows 2000 to add some neat effects on buttons, borders etc.

When I create a window using CreateWindow its not using MS Shell Dlg2 substitute font, how can I add that app wide?

When I create child controls on the window and activate visual style then I get an ugly white border, where it is supposed to be transparent, I have tried severeal ways using WM_CTLCOLORBTN, WM_CTLCOLOREDIT, but I think the only way is to subclass each and every child control (using WM_NCPAINT/WM_NCCALCSIZE) and paint the visual style myself, is that the way to go ?


Please, if you need some sample code I can provide it, I just dont feel like spamming this question with code that will make it harder to read

推荐答案

是的. ..您正在按照正确的方式进行操作.....也请使用GetDCEx.如果您需要任何其他帮助，请发布您的代码

Yes....you are going with proper way.....also use GetDCEx. If you need any further help, please post your code

这是我可以生成的代码.

此示例显示了使用带有Visual Style添加的CreateWindow创建的标准按钮，该按钮具有难看的白色边框(正确地是标准背景画笔)

然后还使用CreateWindows创建了一个子类化的静态控件，然后使用SetWindowLong并使用按钮模板添加了Visual样式，该样式没有难看的白色边框，显示了应该的样子.

确实需要对每个控件进行子类化以删除难看的白色边框吗?

那么，将为每个控件或将要输出的文本添加为​​默认字体的应用程序级字体又如何呢?

This is as short as I can produce it.

This sample is showing a standard created button using CreateWindow added with Visual Style, the button has an ugly white border (properly the standard background brush)

and then a subclassed static control also created with CreateWindows and then used SetWindowLong and added Visual style using a button template, this has not the ugly white border, its showing how it should be.

Is it really neccessary to subclass each and every control to remove the ugly white border?

And how about an app wide Font that will be added as default font for each and every control or text that will be output?
