如何检测可用于普通窗口的主显示屏的可用部分？ [英] How to detect the available part of the main display that's available for normal windows ?

问题描述

在大多数桌面环境中，您有一个或多个操作栏，有时还有停靠的窗口。

On most desktop environments, you have one ore more action bars and sometimes docked windows.

最大化的窗口将使用这些不同的未使用空间屏幕上的东西。这就是我所说的可用空间

A maximized window will used all the space that is not used by these different things on the side of the screen. That's what I'm calling the "available space"

是否有一个Java API来检测可用空间，并尽可能听取可能发生的变化？ / p>

Is there a java API to detect the available space, and if possible to listen to the changes that may occur ?

推荐答案

基本思想是获取对屏幕设备的引用，并从屏幕边界中减去屏幕插图，如下所示

The basic idea is to get a reference to the screen device and subtract the screen insets from the screen bounds as follows

GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironment();
GraphicsDevice gd = ge.getDefaultScreenDevice();

Rectangle bounds = new Rectangle(0, 0, 0, 0);

if (gd != null) {

    GraphicsConfiguration gc = gd.getDefaultConfiguration();
    bounds = gc.getBounds();

    Insets insets = Toolkit.getDefaultToolkit().getScreenInsets(gc);

    bounds.x += insets.left;
    bounds.y += insets.top;
    bounds.width -= (insets.left + insets.right);
    bounds.height -= (insets.top + insets.bottom);

}

现在，您的下一个问题将是确定哪个您实际想要的屏幕设备，此示例仅使用默认屏幕;）

Now, your next problem is going to be to determine which screen device you actually want, this example simple uses the default screen ;)
