Changing width of GridLayout

I use the GridLayout for my JPanel and was wondering, if it's possible to change the width of the columns:

GridLayout grid = new GridLayout(5,2);
panel.setLayout(grid);

Is there a simple way?

The above answer is close. You need to add widgets to the Panel or Frame and not the Layout itself. The Layout just tells the panels/frames how to organize the widgets added to it.

panel.setLayout(new GridLayout(1,2));
panel.add(<your panel widget>);

You can use separate grid layout for each column. 

GridLayout grid = new GridLayout(1,2); 
    GridLayout grid1 = new GridLayout(5,1);
        GridLayout grid2 = new GridLayout(5,1);


        grid.add(grid1);
        grid.add(grid2);

You can now set widths of grid1 one and grid2.

Check the GridLayout api to see that the grid is made so all cells are the same size. If you want a component to be shown at it's preferred size, like (15,15), add it to a JPanel and add the JPanel to the GridLayout. The JPanel will expand to fill the gird cell and allow the component to be shown at it's preferred size.

For a row of different size you'll have to try something else. Nested layouts would be a good starting place...

You could always use the dreaded GridBagLayout.
