取消选中Java中的复选框 [英] uncheck checkboxes in java

问题描述

在我的程序中，无论何时调用此方法，我都希望取消选中所有复选框.有人可以解释为什么它不起作用吗?每当我调用此方法时，仍会选中复选框.

In my program, I want to uncheck all the checkboxes whenever this method is called. Can someone explain why it isn't working? Whenever I call this method the checkboxes are still selected.

private void nextQuestionButtonActionPerformed(java.awt.event.ActionEvent evt) {                                                   

     clearOptions();

}    

public void clearOptions ()   
{ 
    //Make sure the check boxes are not checked
    optionA.setSelected(false);
    optionB.setSelected(false);
    optionC.setSelected(false);
    optionD.setSelected(false);  
}

推荐答案

首先，您需要将所有复选框的代码置于例如状态更改方法&的顶部.之后，取消选中该复选框，您可以创建一个变量，例如state&将变量值设置为false&之后，您可以调用 checkbox.setSelected(false); 或 boolean state = false;.CheckBox.setSelected(state); 就是这样！

first of all you need to bring all of the check box s code on the top of your for example state change method & after that for uncheck the check box you can make a variable like state & put the variable value on false & after that you can call the checkbox.setSelected(false); or boolean state = false; CheckBox.setSelected(state);that's it !!!
