java - 从 JTextField 中删除 InputVerifier

Question

我真的很惊讶this is not in the documentation或at least google .

我有一个类可能需要删除 validator 或将其替换为另一个 validator 。特别是，这些方法是在接口(interface)中定义的:

  /**
   * Add the verifier
   */
  public void bind();
  /**
   * Remove the verifier from input
   */
  public void unbind();

我可以实现绑定(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 validator ？

Answer 1

试试这个方法:

field.setInputVerifier(null);
