Is there a way to create a transparent panel as described by the Apple Human Interface Guidelines in Qt 4.6 (built for OS X 10.6/Cocoa)?

如果没有，在外观和功能上是否有类似的替代？

If not, are there any alternatives similar in look and function?

I understand that Qt is a cross platform toolkit, but I want my application to feel as "native" as possible.

推荐答案

我没有在Mac上试过，但这应该是可能的。以下是 QWidget文档说的内容：

I haven't tried on Mac, but this should be possible. Here's what the QWidget docs say:

创建半透明窗口

Creating Translucent Windows

自Qt 4.5起，可以在支持合成的窗口系统上创建具有半透明区域的窗口。

Since Qt 4.5, it has been possible to create windows with translucent regions on window systems that support compositing.

要在顶级窗口小部件中启用此功能，请将 Qt :: WA_TranslucentBackground 属性设置为 setAttribute（），并确保其背景在您想要部分透明的区域中以非透明颜色绘制。

To enable this feature in a top-level widget, set its Qt::WA_TranslucentBackground attribute with setAttribute() and ensure that its background is painted with non-opaque colors in the regions you want to be partially transparent.

平台注释：

X11：此功能依赖于使用支持ARGB视觉效果和合成窗口管理器的X服务器。

X11: This feature relies on the use of an X server that supports ARGB visuals and a compositing window manager.

Windows：窗口小部件需要设置 Qt :: FramelessWindowHint 窗口标志以使半透明式工作。

Windows: The widget needs to have the Qt::FramelessWindowHint window flag set for the translucency to work.

我想你的面板是一个顶层的小部件，所以一定要按照上面的指示设置 Qt :: WA_TranslucentBackground 。

I imagine your panel is a top-level widget, so make sure to set Qt::WA_TranslucentBackground as directed in the above.
