Properties

Dynamic Images

For example you can create an image using the Java2D libraries and then set the content of the fisheye to the created image, below is an example of how to do this.

<?page title="Auto Generated index.zul"?>
<zk>
	<window title="test of autodisable">
		<fisheyebar><fisheye id="fish1" /></fisheyebar>
		
		<zscript>
		import java.awt.*;
		import java.awt.image.*;
		import java.awt.geom.*;
		
		
		void draw() {
			BufferedImage bi = new BufferedImage(200, 200, BufferedImage.TYPE_INT_RGB);
			Graphics2D g2d = bi.createGraphics();
			Line2D line = new Line2D.Double(0, 0, bi.getWidth(), bi.getHeight());
			g2d.setColor(Color.blue);
			g2d.setStroke(new BasicStroke(100));
			g2d.draw(line);
			fish1.setImageContent(bi);
		}
		
		draw();
		</zscript> 
	</window>
</zk>
