问题描述

解决方案

看起来类没有空白光标开始,所以可以使用方法。



以下是我尝试过的一种似乎工作的方式:

  //透明的16 x 16像素光标图像。 
BufferedImage cursorImg = new BufferedImage(16,16,BufferedImage.TYPE_INT_ARGB);

//创建一个新的空白游标。
Cursor blankCursor = Toolkit.getDefaultToolkit()。createCustomCursor(
cursorImg,new Point(0,0),blank cursor);

//将空白光标设置为JFrame。
mainJFrame.getContentPane()。setCursor(blankCursor);






编辑 p>

关于 JFrame 中没有游标的所有内容的评论,似乎包含在 JFrame 中的组件将最终继承容器的游标( JFrame ),因此如果需要有一个组件出现光标,则必须手动设置所需的光标。



例如,如果 JFrame 中包含 JPanel 可以使用方法:

  JPanel p = ... 
//将JPanel的光标设置为系统默认值。
p.setCursor(Cursor.getDefaultCursor());


Is there anyway to hide cursor other than using transparent gif image?

解决方案

It appears that the Cursor class does not have a "blank" cursor to begin with, so one could define a new "blank" cursor using the Toolkit.createCustomCursor method.

Here's one way I've tried which seems to work:

// Transparent 16 x 16 pixel cursor image.
BufferedImage cursorImg = new BufferedImage(16, 16, BufferedImage.TYPE_INT_ARGB);

// Create a new blank cursor.
Cursor blankCursor = Toolkit.getDefaultToolkit().createCustomCursor(
    cursorImg, new Point(0, 0), "blank cursor");

// Set the blank cursor to the JFrame.
mainJFrame.getContentPane().setCursor(blankCursor);


Edit

Regarding the comment about everything inside the JFrame ending up without a cursor, it seems that the Components which are contained in the JFrame will end up inheriting the cursor of the container (the JFrame), so if it is a requirement to have a certain Component have the cursor appear, one would have to manually set the desired cursor.

For example, if there is a JPanel contained in the JFrame, then one could set the cursor of that JPanel to the system's default using the Cursor.getDefaultCursor method:

JPanel p = ...
// Sets the JPanel's cursor to the system default.
p.setCursor(Cursor.getDefaultCursor());
