在MFC中使圆形按钮生效 [英] Give Effect on round button in mfc

问题描述

我刚刚通过将其设为所有者绘制按钮来创建圆形按钮，并且需要对该按钮生效，现在它看起来不像按钮按钮，而是简单的圆形图.

I just created a round button by making it the button as owner draw and need to give effect on that button , now it appears not like a button button but like a simple round figure

推荐答案

您需要调用Windows API SetWindowRgn.它不仅会创建圆形的可见区域，而且Windowed控件的所有功能都将限于该区域，重要的是鼠标事件.自然地，该区域可以是任何形状，不仅可以是圆形的，还可以通过对基本点集(例如椭圆，矩形等)的理论设置操作的组合来定义.

You need to call Windows API SetWindowRgn. Not only it will create rounded visible region, but all functionality of the Windowed control will be limited to the region, importantly — the mouse events. Naturally, the region can be of any shape, not just rounded but defined by a combination of theory-set operations on the primitive point sets such as ellipse, rectangle, etc.

What SAKryukov says is 100%, just in order to extend it a little, you can take a look at all the articles here[^] in CP in which some users have posted different ways to do specially shaped buttons...

PS: remember to filter by MFC ;)
