使用JSpinner像JTable单元格编辑器

问题描述

单元格保持在NON-editable模式，直到我点击它，对于非编辑我的意思是我不能写入它（它没有集中，所以它不接受输入键盘），但我可以改变上下箭头（键盘）的值。

所以，当我按下一个键时，我必须做什么才能集中表格单元格？

除了这个问题，我的SpinnerEditor类工作得很好。

感谢所有。

解决方案

pre $ b public void focusGained（FocusEvent e）{

//编辑器是（（JSpinner.DefaultEditor）spinner.getEditor（））。getTextField（）;
//必须设置焦点jspinner的文本组件
editor.requestFocus（）;

// this if yo你想选择jspinner的显示文本
SwingUtilities.invokeLater（new Runnable（）{
public void run（）{
System.out.println（run）;
editor.selectAll（）;
}
}）;
}

public void focusLost（FocusEvent e）{}
}）;

i'm using a JSpinner like a table cell editor, i have one annoying problem:

The cell remains in NON-editable mode until i click into it, for NON-editable i mean that i can't write into it(it has not focus so it doesn't accept inputs keyboard) but i can change the value with up-down arrows(of keyboard).

So, what i have to do to focus my table cell as soon as i press a key when it is selected?

Except for that problem my SpinnerEditor class works quite well.

Thanks all.

解决方案

Ok, my solution now is this:

spinner.addFocusListener(new FocusListener() {

    public void focusGained(FocusEvent e) {

        // editor is ((JSpinner.DefaultEditor)spinner.getEditor()).getTextField();
        // necessary to set focus on the text component of jspinner
        editor.requestFocus();

        // this if you want to select the displayed text of jspinner
        SwingUtilities.invokeLater(new Runnable() {
            public void run() {
                System.out.println("run");
                editor.selectAll();
            }
        });
    }

    public void focusLost(FocusEvent e) {}
});
