How to make an added JPanel
visible inside a parent JPanel
?
I am using Netbeans for designing my UI.
I have a MainFrame.java
, which contains two panels; namely headerPanel
and bodyPanel
.
In headerPanel
I have put three buttons,let it be button1
, button2
and button3
.
Also I have created three separate files extending JPanel
, name it panel1
, panel2
and panel3
.
Then I added all my three panels inside bodypanel
in MainFrame.java
in constructor.
bodyPanel.add(panel1);
bodyPanel.add(panel2);
bodyPanel.add(panel3);
I want that on clicking the respective buttons only respective panels should appear in the bodypanel
in mainframe, i.e. if I click button1
then panel1
should be displayed.
I have already tried the following code in button1
mouse listener method:
bodyPanel.validate();
bodyPanel.getComponent(0).setVisible(true);
But panel1
does not appear. I did it cause added components in a panel are allotted index. So first I tried to get the components and then make it visible. It did not work.
