How to align panel in NORTH_WEST

Hello Frederik

The easiest way to do this is to set the JFrame layout to setLayout( null ), and then in your JPanel constructor setBounds( 0, 0, 70, 30 ).

But then your JPanel will have a constant size and it is not a very dynamic way to do it.

Another way to do it is to use a GridBagLayout

It is accually not easy to place objects dynamicialy inside JFrames.

Maybe a GridLayout is easiest to start out with. Later on you can try some of the more complex layouts. You can read about the GridLayout here:

If you want to use the GridBagLayout you need some objects for the grid to outweigth your JPanel with the Jlabel.

You can use empty JPanels for this purpose and then set weightx and weighty higher than the JPanel with the Jlabel.

Look at how things should be placed and pick the appropriate layout.

Border/Grid/GridBag/Flow etc..

I doubt that null layout is a good choice.

Hello guys!

Thank you both for the replies!

Please give svar so I can reward you!

I have to explain that I ran into this problem when I was using a JTabbedPane.

(Then my simple example was not a complete description of the problem.)

How ever I vent for the BorderLayout().

It doesnt look like you can do something like:

getTab(0).setLayout(new BorderLayout());
addTab("Titel", mYPanel, BorderLayout.NORTH);

I finally solved it like:

    private JPanel addPanel(JPanel lastChild, String title)
    {
        JPanel child = new JPanel();
        child.setLayout(new BorderLayout());
        child.add(lastChild, BorderLayout.NORTH);
       
        JPanel parent = new JPanel();
        parent.setLayout(new BorderLayout());
        parent.add(child, BorderLayout.WEST);
       
        TitledBorder titledBorder = BorderFactory.createTitledBorder(title);
        titledBorder.setTitleColor(Color.GRAY);
        titledBorder.setTitleJustification(TitledBorder.LEFT);
        parent.setBorder(titledBorder);
       
        return parent;
    }


and added the Tab like:

addTab(CONNECTION_SETTINGS, addPanel(settingsPanel, SettingsPanel.STEP_1_CONNECTION_SETTINGS) );

I do not know if my nestled panels is best practice but it seems to work.

Best regards
Fredrik

When using JTabbedPane you should add a JPanel to manage the layout inside the tab.
eg.:

tabbedPane.addTab( "Title", null, theJPanel, "Tool Tip Text" );
The second parm is for an icon.

You can pick an appropriate layout for theJPanel, and you should add components to theJPanel...

Just give the points to druesukker.

It is very common to have panels inside panels inside panels.
