Java JEditorPane
我使用 2 JEditorPane 将文本从一个 JEditorPane 传输到另一个。
一旦我传输了数据，我就会执行以下操作：
JEditorPane.setText(null);
JEditorPane.setCaretPosition(0);
但是正如您从附图中看到的那样，返回操作使提示出现在下方一行。我该如何解决这个问题？
编辑：您认为以下内容正确吗？如果是这样，那么为什么插入符号不将自己定位到字符 0 位置？
private class MyKeyAdapter extends KeyAdapter {
@Override
public void keyPressed(KeyEvent ke) {
int kc = ke.getKeyCode();
if (kc == ke.VK_ENTER) {
System.out.println(editorPaneHistory.getText());
System.out.println(editorPaneHomeText.getText());
editorPaneHistory.setText(editorPaneHomeText.getText());
//JEditorPane - editorPaneHistory
//JEditorPane - editorPaneHomeText
editorPaneHomeText.setText(null);
editorPaneHomeText.setCaretPosition(0);
}
}
}
im using 2 JEditorPane to transfer text from one to another.
once i have transfered the data i do the following:
JEditorPane.setText(null);
JEditorPane.setCaretPosition(0);
but as you can see from the attached image the return action makes the prompt appear a row down. how can i fix this?
EDIT: does the following seem correct to you? if so then why is caret not positioning itself to chracter 0 position?
private class MyKeyAdapter extends KeyAdapter {
@Override
public void keyPressed(KeyEvent ke) {
int kc = ke.getKeyCode();
if (kc == ke.VK_ENTER) {
System.out.println(editorPaneHistory.getText());
System.out.println(editorPaneHomeText.getText());
editorPaneHistory.setText(editorPaneHomeText.getText());
//JEditorPane - editorPaneHistory
//JEditorPane - editorPaneHomeText
editorPaneHomeText.setText(null);
editorPaneHomeText.setCaretPosition(0);
}
}
}

代码运行后，JEditorPane 将通过插入换行符以通常的方式对 Enter 键做出反应。尝试调用 ke.consume() 来“消耗”事件，这样 JEditorPane 本身就不会处理它。
After your code runs, the JEditorPane is reacting to the enter key in the usual way, by inserting a newline. Try calling
ke.consume()to "consume" the event so that the JEditorPane itself doesn't handle it.不要使用 KeyListener。您应该使用自定义操作。这样就可以替换默认的Action了。阅读按键绑定。
Don't use a KeyListener. You should be using a custom Action. This way you can replace the default Action. Read up on Key Bindings.
