Repaint Objects when Component is resized

Module Development
1

Hi all and a happy new year to all developpers :wink:

I’m making a Chart based on AbstractVisionComponent for Client/Designer.
I just want to make the Chart getting the whole space of the component.
I use the getWidth and getHeigth methods of the AbstractVisionComponent, but I can’t get the event.

Can anyone help ?
Do I have to make a ChangeListener for these properties ?
:scratch:

Thanks for help.

I’ve use the following code in an AbstractVisionComponent which contains other components, to resize the sub-components according to the main :

	import java.awt.event.ComponentListener;
	
	Add to the constructor :
	
	ComponentEventListener cl = new ComponentEventListener();
	this.addComponentListener(cl);
	
	Add this subclasse in the class which extends AbstractVisionComponent :
	
	public class ComponentEventListener implements ComponentListener {
		public void componentHidden(ComponentEvent e) {
		}

		public void componentMoved(ComponentEvent e) {
		}

		public void componentResized(ComponentEvent e) {
		
			// resize your subcomponent here...
			canvas.setSize(getWidth(), getHeight());
			panel.setSize(getWidth(), getHeight());
		}

		public void componentShown(ComponentEvent e) {
		}
	}

hope this helps !
