使子窗口的标题/边框透明 [英] Make caption/border of child window transparent

问题描述

在Win32应用程序中，我想在主窗口中创建一个子窗口.我在调用CreateWindowEx时将这些样式分配给了子窗口:

In my Win32 application, I want to create a child window within the main window. I assigned these styles to the child window when calling CreateWindowEx:

WS_CHILDWINDOW | WS_VISIBLE | WS_VSCROLL | WS_HSCROLL | WS_SIZEBOX | WS_CAPTION

我得到的子窗口具有标题和可调整大小的边框.但是，标题中没有关闭按钮，并且子窗口的标题/边框不是透明的.我正在Windows 7中使用aero主题.

这是屏幕截图:



如何在字幕上添加关闭按钮?如何使字幕/边框透明?

此外，您可能没有注意到，但子窗口的左上角和右上角最初是黑色背景.如果我拖动窗口或调整窗口大小，黑色背景将消失.

The child window I get has a caption and a resizable border. However there''s no close button in the caption, and the caption/border of the child window is not transparent. I''m using the aero theme in Windows 7.

Here is the screen shot:



How to add close button to the caption? How can I make the caption/border transparent?

What''s more, you may not notice but initially the upper left and upper right corner of the child window has a black background. If I drag the window or resize it, the black background will disappear. Why is that and how to fix this minor problem?

推荐答案

请尝试使用WS_SYSMENU样式.

哪个画笔设置为您的窗口类?您可以粘贴用于创建子窗口的示例代码吗?

问候，

Please try with WS_SYSMENU style.

Which brush is set to your window class? Can you paste sample code for creating the child window?
