I have created a property editor :
import ca.cmhc.ifm.portal.dataservice.dataobjects.location.Region;
import java.awt.Color;
import java.awt.Component;
import java.awt.Graphics;
import java.awt.Rectangle;
import java.beans.PropertyEditorSupport;
import java.util.ArrayList;
import javax.swing.BorderFactory;
import javax.swing.JLabel;
import org.openide.explorer.propertysheet.ExPropertyEditor;
import org.openide.explorer.propertysheet.PropertyEnv;
/**

*/
public class MessagePropertyEditor extends PropertyEditorSupport implements ExPropertyEditor {
private String localValue = "";
private PropertyEnv env;
private ArrayList<Region> regions;
private String messageText = "";
private JLabel renderer;
public MessagePropertyEditor(String messageText) {
super();
this.messageText = messageText;
renderer = new JLabel(this.messageText);
}
@Override
public String getAsText() {
return "";
}
@Override
public boolean isPaintable() {
return true;
}
@Override
public void paintValue(final Graphics g, final Rectangle r)
{
renderer.setBorder(BorderFactory.createEmptyBorder(0, 3, 0, 0));
renderer.setForeground(Color.blue);
//renderer.setText("<html><i>" + this.messageText.replace("\n", " ") + "</i>");
renderer.setText(this.messageText.replace("\n", " "));
renderer.setBounds(r);
renderer.paint(g);
}
@Override
public Component getCustomEditor() {
MessageCustomEditor panel = new MessageCustomEditor(messageText);
return panel;
}
@Override
public boolean supportsCustomEditor() {
return true;
}
public void attachEnv(PropertyEnv env) {
this.env = env;
}
}
I am trying to find a way to force a repaint of this component. The objective in the end is to have a timer change the background color at specific intervals, making the background flash.
The PropertyEditor does not seem to have a "repaint" or a "invalidate" method, so I was wondering how to get it to repaint.
I have tried to invalidate/call repaint on the JLabel used to create the graphics, but it does not call paintValue()
I have also tried to call the method directly, but I do not know where to get Graphics and the Rectangle needed as parameters....
Anyone has an idea on how to force the PropertyEditor to repaint?
Thanks
Do you want to repaint the property editor, or the component that represents it on the screen? In the latter case, try
editor.getCustomEditor().repaint().
