How can I disable the spacebar in a textfield in JavaFX?
问题
我有一个问题。我想完全禁用文本框的空格键，以便我的输入中没有空格。这是否可能？
if (event.getCode() == KeyCode.SPACE) {
System.out.println("Spacebar key detected!");
textfieldName.setText(textfieldName.getText().substring(textfieldName.getLength() - 1));
}
这是我找到的内容，但我想完全禁用空格键。有人可以帮我吗？
谢谢回答

I got a question. I would like to disable the space bar completely for that textfield so there are no spaces in my input. How is that possible?
if (event.getCode() == KeyCode.SPACE) {
System.out.println("Spacebar key detected!");
textfieldName.setText(textfieldName.getText().substring(textfieldName.getLength() -1));
}
});
This is what I found, but I would like to disable the spacebar completely. Can anyone help me please?
Thanks for answering

或许 这个链接 会有帮助
mytextfield.addEventFilter(KeyEvent.KEY_PRESSED, new EventHandler<KeyEvent>() {
public void handle(KeyEvent event) {
if (event.getCode() == KeyCode.SPACE) {
event.consume(); // 取消空格键
}
}
});
另一种方法 是像评论中的 @n247s 建议的那样 进行过滤
英文:
Maybe this will help
mytextfield.addEventFilter(KeyEvent.KEY_PRESSED, new EventHandler<KeyEvent>() {
public void handle(KeyEvent event) {
if (event.getCode() == KeyCode.SPACE) {
event.consume(); // to cancel space key
}
}
});
Another way is to filter it like @n247s suggested in the comments
