JPanel is added onto other Jpanel on togglebutton Click
问题 I am trying to make a popup panel which is activated with the help of JToggleButton. I want the JPanel to be added onto the other Jpanel when ToggleButton is selected and hides when the ToggleButton is deselected. I have declared the JToggleButton and used ItemListener. But What is happening is when i select the ToggleButton a panel is created if i deselect and Select it again another JPanel is added again and so on and After 5 clicks , Nothing appears. public static JPanel
