纯C语言开发的图标/图片按钮源代码，这个程序中使用了字体font, 绘制形状shape, 绘制边edge, 绘制颜色color, 使用刷子brush 和钢笔pen完成。 -Although Windows has a really cool GUI, sometimes the way standard buttons look quite does not meet our requirements. We may then choose buttons with a style called "owner-draw". The owner has to draw the button in every aspect (background, border, text, image) of every situation that requires drawing (click, enable, focus, etc.).It took me days to come up with something functional, Now here is some simple, reliable code: if it proves useful I will write something about owner-draw buttons with text (dealing with fonts, shapes, edges, colorrefs, brushes and pens).
