Problems Resizing TextArea

[Glyph]

I cant seem to resize a text area box.

I tried resizing the text area and the panel that I put it in.

What am I doing wrong?




method

     public JPanel createTextAreaPanel() {
        textArea = new TextArea();
        textArea.setSize(TEXT_AREA_FRAME_WIDTH, TEXT_AREA_FRAME_HEIGHT);

        JPanel panel = new JPanel();
        panel.add(textArea);
        panel.setSize(TEXT_AREA_FRAME_WIDTH, TEXT_AREA_FRAME_HEIGHT);
        return panel;

    }

A panel's width and height is in pixels. A textarea's width and height is in columns and rows.

That's not true: only the JTextArea constructor considers those sizes as lines and colums, the setSize( ... ) method is just inherited from the Component class. The JPanels are equiped with LayoutManagers, I can understand that the JTextArea can't be resized at will.

kind regards,

Jos

Oops. Sorry, had constructors on the mind.

[Glyph]

Thanks! I see now that I just needed to specify columns and rows in the TextArea Constructor. After that -- setting the panels size that contains the TextArea seemed to have no effect.

That's not it; see my reply #3 where I not only mercilessly corrected Masijade's mistake but also gave a hint w.r.t. your problem.

kind regards,

Jos ;-)
