我真的很惊讶这不在文档中,或者至少不在 google中。
我有一个类可能需要删除验证器或用另一个替换它。具体来说,这些方法是在接口中定义的:
/**
* Add the verifier
*/
public void bind();
/**
* Remove the verifier from input
*/
public void unbind();
我可以实现bind
:
/**
* Binds the events to the field using InputVerifier
*/
@Override
public void bind() {
//Internal verifier
final SettingsInputVerifier<T> verif = this.verifier;
//Event to be called if new value is valid
final ValueChanged<T> onchange = this.onchange;
//Only works when you leave the field
field.setInputVerifier(new InputVerifier() {
@Override
public boolean verify(JComponent in) {
//If verification fails, return false and ignore the value
if(!verif.verify(in))
return false;
//Sucessful verification means we get the value and update it
onchange.changed(verif.value(in));
return true;
}
});
}
但是如何从 JTextField取消设置输入验证器?
