Windows taskbar height/width
提问by mastaH
I can't figure out how to get the windows taskbar height dynamicaly to set my application fullscreen.
As you know, taskbar can be in four positions: bottom, top, left or right, so I'm wondering if it's possible to also know the current position to set the window bounds.
我不知道如何动态获取 Windows 任务栏高度以设置我的应用程序全屏。
如您所知，任务栏可以位于四个位置：底部、顶部、左侧或右侧，所以我想知道是否也可以知道当前位置来设置窗口边界。
EDIT: Using Lukas link I tryied this:
编辑：使用 Lukas 链接我尝试了这个：
GraphicsDevice myDevice;
Window myWindow;
try {
myDevice.setFullScreenWindow(myWindow);
...
} finally {
myDevice.setFullScreenWindow(null);
}
But I'm gettin a NullPointerException

When you create your JFrame. Make a call to the setExtendedState()method in the JFrame API
当你创建你的JFrame. 调用setExtendedState()JFrame API 中的方法
jFrame = new JFrame("TESTER");
jFrame.setExtendedState(JFrame.MAXIMIZED_BOTH);
The MAXIMIZED_BOTH setting will set your window to fullscreen and automatically take into account the position of the Taskbar.
MAXIMIZED_BOTH 设置会将您的窗口设置为全屏并自动考虑任务栏的位置。

It is possible to obtain the Windows taskbar height if necessary:
如有必要，可以获取 Windows 任务栏高度：
Dimension scrnSize = Toolkit.getDefaultToolkit().getScreenSize();
Rectangle winSize = GraphicsEnvironment.getLocalGraphicsEnvironment().getMaximumWindowBounds();
int taskBarHeight = scrnSize.height - winSize.height;

If you want your Application to run in full-screen mode, you can enter it by getting a suitable GraphicsDeviceand using the setFullScreenWindow(Window)-method:
如果您希望您的应用程序以全屏模式运行，您可以通过获取合适的GraphicsDevice并使用setFullScreenWindow(Window)-method来输入它：
GraphicsDevice myDevice = GraphicsEnvironment.
getLocalGraphicsEnvironment().getDefaultScreenDevice();
Window myWindow;
try {
myDevice.setFullScreenWindow(myWindow);
...
} finally {
myDevice.setFullScreenWindow(null);
}

You can use:
您可以使用：
int taskbarheight = Toolkit.getDefaultToolkit().getScreenSize().height
- GraphicsEnvironment.getLocalGraphicsEnvironment().getMaximumWindowBounds().height();
or you can use, as well:
或者你也可以使用：
JFrame frame = new JFrame();
frame.setSize(GraphicsEnvironment.getLocalGraphicsEnvironment().getMaximumWindowBounds().getSize();

This is part of a program I wrote:
这是我写的程序的一部分：
public enum Location {
TOP, RIGHT, BOTTOM, LEFT;
}
private static final class Taskbar {
public final Location location;
public final int width, height;
private Taskbar(Location location, int width, int height) {
this.location = location;
this.width = width;
this.height = height;
}
public static Taskbar getTaskbar() {
Rectangle other = GraphicsEnvironment.getLocalGraphicsEnvironment()
.getMaximumWindowBounds();
return new Taskbar(other.x != 0 ? Location.TOP
: (other.y != 0 ? Location.LEFT
: (other.width == IFrame.width ? Location.BOTTOM
: Location.RIGHT)), IFrame.width
- other.width, IFrame.height - other.height);
}
}
Essentially, calling Taskbar.getTaskbar()will give a taskbar containing information on its location (TOP, RIGHT, BOTTOM, LEFT), its width, and its height.
本质上，调用Taskbar.getTaskbar()将给出一个包含位置（TOP、RIGHT、BOTTOM、LEFT）、宽度和高度信息的任务栏。
