should I dispose of a font when... [message #448028] Mon, 27 December 2004 06:45 Go to next message

So far, I've been assigning a value to a font and disposing of the font
when I dispose of the parent object. However, I'm about to change the
font while the object is still around- should I dispose of the old font
before reassigning the new font?

For example, in the following basic class structure, should I call
"font.dispose()" in the changeFont method?

MyClass {
private Font font;
public MyClass() {
Font font = ...;
}

public void changeFont(FontData fd) {
// should I call font.dispose() here?
font = new Font(null, fd);
}

protected void widgetDisposed() {
// called from dispose listener
font.dispose();
}
}

Many thanks.

Yes you should. You created the font so you need to dispose of it when
no longer needed.
