Could anyone help me please to draw this area transparent?

推荐答案

如果您想要绘制背景，您可以自己动手。 Messagehandler OnEraseBackground很好，可以在该函数中执行 CDC :: FillSolidRect（....）。 >


对于某些transpaerency，您应该阅读：使用分层Windows

if you want the background to be painted you got do it yourself. The Messagehandler OnEraseBackground is fine, to do CDC::FillSolidRect(....) in that function

For some transpaerency you should read this: Using Layered Windows

你好 C3D1 ，

• 为第一个 - Tab控件外部背景在发送给父级的 WM_PRINTCLIENT 消息中被删除
• 选项卡控件必须具有 WS_CLIPSIBLINGS 样式。
• 并且应该在选项卡底部设置选项卡控件。控制 SetWindowPos（hTab，HWND_BOTTOM，0,0,0,0，SWP_NOSIZE | SWP_NOMOVE）; 。

Hello C3D1,

• for the first - the Tab controls outer background is erased in the WM_PRINTCLIENT message sent to the parent window.
• The tab control must have the WS_CLIPSIBLINGS style.
• And you should set the tab control at the bottom of the controls by SetWindowPos(hTab,HWND_BOTTOM,0,0,0,0,SWP_NOSIZE|SWP_NOMOVE);.
