自定义按钮（API) 修改按钮的颜色

[tangshan305]

我先创建了一个窗口，在在上面创建了几个BUTTON 按钮(用预定义的"button"类)。
我怎么改变这个按钮的背景颜色？（我用的是纯的win 32 API 编程）希望
能够尽量的详细点 非常感谢！我是一名初学者，希望能给了例子或代码。谢谢！

从CBUTTON类派生一个类，，然后OnEraseBkgnd之类的函数可以改变颜色

[tangshan305]

能具体点吗？
我对这块一点都不熟悉！
谢谢了

。。。楼主我建议你将《WINDOWS程序设计》好好看一下，里面有很详细的讲解

父窗口响应WM_CTLCOLORBTN消息

[tangshan305]

我试了，不行的，对按钮根本不起作用

SetWindowLong(按钮HWND，GWL_WNDPROC, ...);
处理WM_DRAWITEM消息，创建按钮的时候CreateWindow带上BS_OWNDERDRAW属性

这是代码 能帮忙说下吗？我刚开始学习这个

谢谢 各位
搞定了，
就加了一个可以重绘的风格
然后就可以自己修改颜色了

楼主说的是这个么？？？

关键字：

3D Button API是由MultiMedia Soft开发的最新的3D按钮软件开发包（SDK），源于ActiveX 控件3D Active Button Magic的经验，在您现有的应用程序和新的开发工具中，它代替了过时的Windows平面直角按钮。对于喜欢使用DLL组件而不喜欢ActiveX控件的开发者来说，它也是3D按钮的替代品。此产品包含在产品集合 3D Button Suite 中。

具体功能：

不论您为销售点市场开发一个简单的Windows应用程序、一个互动对话亭或是触屏应用程序，3D Button API都会为您提供一个出色用户界面，并快速将您的应用程序及时推向市场。

用新版的SDK，您可以创建具有现代渲染界面的出色的3D按钮，例如Aqua, Gel, Vista's "Aero", Office 2003, Office 2007等：请看下面一些小界面的外观图：



您的应用程序已经开发出来了？没问题！不必改变现有的“业务逻辑”代码，仅用几步您就可以改变按钮的“外观和感觉”。您只需在3D Button API的函数中添加几个调用，就可以改变按钮的外观。

停止浪费时间，您自己设计位图按钮并开始使用3D Button API。改变用户界面，用这个精心制作的3D按钮软件开发包（SDK）来设计，仅需几分钟的时间就可以完成过去需要几天甚至几个月的任务。

给您的windows，对话框，窗体一个全新的样子，用您最喜欢的形状，3D效果、界面、结构、位图、光标、动画、声音、颜色和字体。在试用包里您会发现一些示例程序，它们向您展示了这个强大软件的易用性。
