Hi,
I am new to ULC and am having some problems with my first few attempts to
check if ULC will work for my planned software. I need to use paintComponent
as in the basic 'MyPanel' example below. I have searched the old posts
here and found an example that uses 'UiJPanel' that would seem to be an
option, however I can't find the '*import* com.ulcjava.base.client.UiJPanel'.
Can somebody please point me in the right direction. Is there a ULC
substitute for JPanel ?? If not is there any examples as to how I go about
painting a grid or likewise that would help me get started.
Thank you for any help.

package painting;
import javax.swing.SwingUtilities;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.BorderFactory;
import java.awt.Color;
import java.awt.Dimension;
import java.awt.Graphics;
public class SwingPaintDemo2 {
public static void main(String[] args) {
SwingUtilities.invokeLater(new Runnable() {
public void run() {
createAndShowGUI();
}
});
}
private static void createAndShowGUI() {
System.out.println("Created GUI on EDT? "+
SwingUtilities.isEventDispatchThread());
JFrame f = new JFrame("Swing Paint Demo");
f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
f.add(new MyPanel());
f.pack();
f.setVisible(true);
}
}
class MyPanel extends JPanel {
public MyPanel() {
setBorder(BorderFactory.createLineBorder(Color.black));
}
public Dimension getPreferredSize() {
return new Dimension(250,200);
}
public void paintComponent(Graphics g) {
super.paintComponent(g);
// Draw Text
g.drawString("This is my custom Panel!",10,20);
}
}
