Hello guys i just created a GUI for my application and this is first time its not working.. Well no errors in code just that nothing happends when the checkbox is pressed.. Here is what i wrote.

          if(CheckBox.isSelected()){ 
                    JComboBox1.setVisible(false);
		    JComboBox2.setVisible(false);
		    JComboBox3.setVisible(false);
                    JComboBox4.setVisible(false);
                    JComboBox5.setVisible(true);
                    JComboBox6.setVisible(true);
                    JComboBox7.setVisible(true);
                    JComboBox8.setVisible(true);
                    JComboBox9.setVisible(true);
                    JComboBox10.setVisible(true);
                    JComboBox11.setVisible(true);
                }

The thing is that JComboBox 5-11 is set visible to false when the GUI is started and when you press this they will become visible and the other ones will be not visible.. Is there anything i did wrong or why is this not working properly?

Did you add ChangeListener for CheckBox?

[TheCompBoy]

No man.. Is that like the same to make action listener for button ?

[macosxnerd101]

Yes. Remember that GUI programming is event-driven, and you need Listeners to respond to events. As always, start with the documentation.

[TheCompBoy]

        ChangeListener changeListener = new ChangeListener() {
            public void stateChanged(ChangeEvent changeEvent) {
               if(CheckBox.isSelected()){
	           JComboBox1.setVisible(false);
	           JComboBox2.setVisible(false);
	           JComboBox3.setVisible(false);
	           JComboBox4.setVisible(false);
	           JComboBox5.setVisible(true);
                   JComboBox6.setVisible(true);
                   JComboBox7.setVisible(true);
	           JComboBox8.setVisible(true);
	           JComboBox9.setVisible(true);
	           JComboBox10.setVisible(true);
	           JComboBox11.setVisible(true);
	      }
      }
    };

Thats what i did but still not working..

[macosxnerd101]

Remember you need to add it to the JCheckBox you want to listen to.

[TheCompBoy]

Oh how would i do that ?

[macosxnerd101]

Did you even read the documentation? I linked to it.

[TheCompBoy]

Yes but i found nothing that i was looking for.. I have a hard time reading those documentation i am working on learning how to browse them and learning how to read em.

[macosxnerd101]

The method is addChangeListener(). Seriously, read the documentation. If it doesn't say static, you know how to invoke a method on an object. The documentation is really self-explanatory.

[TheCompBoy]

Sorry but i don't have much experience of reading the documentation its all new to me.

[TheCompBoy]

Seems like we have some corrupt moderators here.

[HarryBo123]

Ohh I think I found it. Ohh wait no dw.

[TheCompBoy]

You need to make like this for example CheckBox.addChangeListener(changelistener);

I find it funny I come onto this forum new looking for help and all my posts are being removed by this moderator.
