Calling setScale on scaleDecorator doesn't update the display
-------------------------------------------------------------
Key: PIVOT-783
URL: https://issues.apache.org/jira/browse/PIVOT-783
Project: Pivot
Issue Type: Bug
Components: wtk
Affects Versions: 2.0, 2.0.1
Reporter: Bill van Melle
When you call setScale on a scaleDecorator that's already in the display tree,
the display does not update. You can't see the effect of the change until
something else causes a repaint.
Looking at the code, isn't this an issue for decorators in general? I don't see
any mechanism for decorators to notify the component (or components?) that they
are attached to that they've changed. If you're not going to notify, then
shouldn't decorators be immutable objects? (Of course, that would break a lot
of code.)
FWIW, a demonstration:
<Window title="Scale change" maximized="true"
xmlns:bxml="http://pivot.apache.org/bxml";
xmlns:effects="org.apache.pivot.wtk.effects"
xmlns="org.apache.pivot.wtk">
<BoxPane orientation="vertical" preferredWidth="300">
<PushButton buttonData="Change">
<buttonPressListeners>
function buttonPressed(button) {
scaleDecorator.setScale(2.0);
}
</buttonPressListeners>
</PushButton>
<Label text="This text should get twice as big when I push the button">
<decorators>
<effects:ScaleDecorator bxml:id="scaleDecorator"
horizontalAlignment="left" verticalAlignment="top" />
</decorators>
</Label>
</BoxPane>
</Window>
