convert JFrame to JComponent

I am trying to create grab the gpahicConxtex of JComponent atr save it to a file, which works fine. Now I want to do this same thing on the JFrame.

The thing is that I don't want to show the JFrame to the user.

public static BufferedImage createImage(Object _component,

int imageType){

Component component=null;

if (_component instanceof JComponent) {

component = (JComponent) _component;

}else if(_component instanceof JFrame){

component = (JFrame) _component;

}

System.out.println(" Comp Type="+(_component instanceof JFrame));

System.out.println( component.getPreferredSize() );

Dimension componentSize = component.getPreferredSize();

component.setSize(componentSize); //Make sure these

//are the same

BufferedImage img = new BufferedImage(componentSize.width,

componentSize.height,

imageType);

Graphics2D grap = img.createGraphics();

grap.fillRect(0,0,img.getWidth(),img.getHeight());

component.paint(grap);

return img;

}

capture in what way? those attributes aren't related to any graphics context, they're just attributes of the JFrame. you can capture and serialize them as normal
