I just wrote a simple code where I want a canvas to appear in the CENTER of a JFrame and a config panel to appear in the NORTH of the same JFrame.However after adding them both the 'canvas' doesn't get displayed at all.If I only add the canvas it does get displayed but as soon as I add the config panel it doesn't get displayed anymore.
Furthermore if I try to add something else in the SOUTH of the same JFrame I get a illegal component position error no matter what..
I'm a complete noob when it comes to Swing so sorry if the answer is obvious but I tried googling and researching this for the last few hours without any luck.
Here's what I tried:
public class MainFrame extends JFrame {
ConfigPanel configPanel;
ControlPanel controlPanel;
DrawingPanel canvas;
public MainFrame() {
super("My Drawing Application");
init();
}
private void init() {
setDefaultCloseOperation(EXIT_ON_CLOSE);
canvas = new DrawingPanel(this);
configPanel = new ConfigPanel(this);
controlPanel=new ControlPanel(this);
add(canvas,CENTER);
add(configPanel,NORTH);
add(controlPanel,SOUTH); //this gives me a illegal component position error
pack();
}
}
please try getContentPane().add(controlPanel, SOUTH); instead of add(controlPanel, SOUTH);
do that for every component in the code you provided...
