    Default Adding JButton to JInternalFrame, grid doesnt work..

    Im making this SQL manager GUI software.
    Mainly for my own use, but If I succed I'll ofcourse give it out fo free :)

    Anyways, I got a problem.
    I got this jInternalFrame
    And then I do this:
    Java Code:
    JButton b = new JButton(name);
    		b.setSize(240, 20);
    		JLayeredPane c = (JLayeredPane) DB.getLayeredPane();
    		GridBagConstraints c1 = new GridBagConstraints();
    		c1.gridy = initDatabases;
    		c1.ipadx = 100;
    		c1.fill = GridBagConstraints.HORIZONTAL;
    Simply, I create a button in this method. Then I add it to the layerdPane
    And the DB (jInternalFrame) is suppose to have GridBagLayout
    But it doesnt work because as I have added 3 buttons
    Then they should be after eachother, moving down 1 grid for each button.

    BUT that doesnt work :(
    Idk why but they all end up on same position..
    Do you know why? Please reply if you do :)

    From what I can tell in this small code snippet, you don't appear to be using GridBagLayout correctly, in particular the GridBagConstraints. Where are you setting the gridx, height, width, weight, etc...

    Have you gone through the GridBagLayout tutorials?

    Myself, I try to avoid using this layout unless necessary.

    I was indeed :D
    Just before reading this I realised that I had done:
    JInternalFrame.setLayout(new GridBagLayout());
    But I wasnt adding them to the internalframe but to the layoutpane!!
    So I set the layoutpane on to GridBagLayout and now it works :D

    Thanks for your time :)
