通过Aqua外观禁用JInternalFrames周围的阴影 [英] Disabling the shadow around JInternalFrames with the Aqua Look and Feel

问题描述

在具有原生Aqua Look and Feel的Mac OS X上，JInternalFrames的阴影是边框的一部分.当内部框架最大化时，阴影仍然可见并且占用大量空间.

On Mac OS X with the native Aqua Look and Feel, JInternalFrames have a shadow that is part of the frame border. When the internal frame is maximized, the shadow is still visible and takes a lot of space.

有没有一种方法可以在不切换到其他外观的情况下消除阴影?

Is there a way to remove this shadow without switching to another look and feel?

推荐答案

在OpenJDK中研究了Aqua L& F代码后，我发现了一个未记录的属性，可让您更改内部框架的样式.可以使用以下方法去除阴影:

After digging into the Aqua L&F code in OpenJDK I found an undocumented property that let you change the style of an internal frame. Shadows can be removed with this:

internalFrame.putClientProperty("JInternalFrame.frameType", "normal");
