Hey, I'm making an app where I use an uneditable JTextPane, and now I want to have line numbers next to it (see http://forum.codecal...-your-data.html for more info if you wanna know what I'm making)

It works fine if I add enough line numbers. Where with "enough" I mean, more than the height can handle.
Added a red border around the lineNumberPanel:

But I don't want to have more line numbers than needed. Partially because it creates an unneeded scrollbar, but also because it's prettier if there are as many line numbers as there are lines.

But when I do that, then there's a vertical-align = center going on...

(I think i'm "stuck" with a gridbaglayout, because my 1st line number needs to be a bit lower than the top, I as well need 1 extra pixel to match the correct height at every line item (or increase font size by 1, which I don't want to do))

Anyone has an idea to make it align to the top?

Line number code:

        GridBagConstraints c = new GridBagConstraints();

        c.gridx = 0;


        for(int i=0 ; i<lines ; i++){

            c.gridy = i;

            if(i ==0){

                c.insets = new Insets(11,0,0,0);

            } else {

                c.insets = new Insets(1,0,0,0);

            }


            JLabel number = new JLabel((i + 1) + "");

            number.setFont(mainFont);

            lineNumbers.add(number, c);

        }

Oh, if it matters, the jpanel with gridbaglayout(line number panel) is inside a BorderLayout jpanel at the WEST.

:glare: Why do I always find it myself within an hour of posting the question.
Solution: Before adding the lineNumbers panel to the west of the borderlayout panel, add it in a flowlayout panel. (I could've sworn I tried this before... guess not :bad:)

        JPanel flowPanel = new JPanel();

        flowPanel.add(lineNumbers);

        codeAndLinePanel.add(flowPanel, BorderLayout.WEST);

I can't tell you how many questions I've resolved by simply formulating the question and making sure I'm not sounding like an idiot. XD
