RE: Mix SVG and Swing components
I am trying to insert the Swing components in the painting chain. The swing
component is scaled, but the area is not increased. The text and the cursor
in the swing component become larger, but the area occupied by the swing
component is not increased.
Any suggestions. I am attaching the program too.
See the CustTextField is used to introducte JTextField into the painting
chain.
Any help is really appreciated.

Only if you can insert yourself in the components repaint chain. So for example if you were to override the paintChildren method from JComponent you might be able to adjust the graphics object prior to drawing the children to scale/translate them as desired. -Original Message- From: Tonny Kohar [mailto:[EMAIL PROTECTED] Sent: Wednesday, January 19, 2005 9:16 PM To: 'batik-dev@xml.apache.org' Subject: Re: Mix SVG and Swing components Hi, I am required to add Swing components to the SVG canvas.

RE: Mix SVG and Swing components
Thanks for the suggestion. The problem with this approach is the swing
components will not be scalable.
I have created a class that extends AbstractGraphicsNode to display the
swing component.
public class SwingGraphicsNode
extends AbstractGraphicsNode
implements GraphicsNodeMouseListener,
GraphicsNodeKeyListener,
GraphicsNodeChangeListener {
JButton fButton = null;
public SwingGraphicsNode() {
//Test code
fButton = new JButton(Button);
setPointerEventType(ALL);
}
public void paint(Graphics2D g2d) {
primitivePaint(g2d);
}
public void primitivePaint(Graphics2D g2d) {
Rectangle2D bounds = getBounds();
g = g2d.create();
g.translate((int)bounds.getX(), (int)bounds.getY());
fButton.getModel().setPressed(true);
fButton.paint(g);
}
//The mouse events are registered in Bridge Extension class
//Think that mousePressed is called whenever mouse is pressed on the
respective button
public void mousePressed(GraphicsNodeMouseEvent evt) {
// TODO Auto-generated method stub
System.out.println([mouse pressed]);
//fButton.getModel().setPressed(true);
fButton.setForeground(Color.RED);
fButton.setBackground(Color.GREEN);
Rectangle2D bounds = getBounds();
fButton.repaint();
setVisible(false);
setVisible(true);
}
}
The button's foreground and background color are changed only when mouse
button is released. I expected that the color of the button will change
immediately when the mouse button is pressed.
Any issues in the program? Any workarounds? Glad to know.

Hi Venkataramana, You might want to talk with Lukasz as he appears to be working on this issue as well. Venkataramana_Jaladurgam wrote: Thanks for the suggestion.

Any issues in the program? Any workarounds? Glad to know. What you need to do is figure out how to tie the Swing 'repaint' request system into the GVT 'update' system. Since I don't know the details of the Swing system I can't really help that much. See my response to Lukasz (mail archives) as it provides some hints. -Original Message- From: Tonny Kohar [mailto:[EMAIL PROTECTED] Sent: Wednesday, January 19, 2005 9:16 PM To: 'batik-dev@xml.apache.org' Subject: Re: Mix SVG and Swing components Hi, I am required to add Swing components to the SVG canvas.
