Roger Whitcomb commented on PIVOT-966:
--------------------------------------
In the Javadoc for ScaleDecorator it says this:
* Decorator that scales the painting of a component along the X and/or Y axes.
* <p> Generally speaking, decorators don't force a repaint of the component(s)
* they are attached to when their parameters are changed. So, if this decorator
* is changed after being applied to a particular component (e.g., to do a
* dynamic resize) then either the component.repaint() method must be called or
* the decorator should be removed and added again to force a repaint with the
* new scale.
So, does it help if you attach the ScaleDecorator to the Window AFTER setting
all the decorator parameters (esp. the scale factor)? Something like this:
....
final ScaleDecorator sd = new ScaleDecorator();
sd.setHorizontalAlignment( HorizontalAlignment.LEFT );
sd.setVerticalAlignment( VerticalAlignment.TOP );
sd.setScale( 2.0f );
sd.update();
window.getDecorators().add( sd );
window.open(display);
....
(You've probably tried this, but just wanted to check...)
Thanks,

> UI zooming and buttons detection in Apache Pivot at program start
> -----------------------------------------------------------------
>
> Key: PIVOT-966
> URL: https://issues.apache.org/jira/browse/PIVOT-966
> Project: Pivot
> Issue Type: Bug
> Components: wtk-effects
> Affects Versions: 2.0.4, 2.1
> Environment: Ubuntu 14.04 LTS 64bit, Oracle JDK 1.7.0-65
> Reporter: Vesa Muukka
> Assignee: Sandro Martini
> Fix For: 2.1, 2.0.5
>
>
> Zooming UI at program start wents right but all buttons responds from wrong
> locations (as if the zoom/scale factor would still be the default 1.0).
> This effect can be easily tested with ApachePivot
> org.apache.pivot.demos.text.TextPaneDemo
> by adding ScaleDecorator & setScale before window.open(display) call like
> this:
> ....
> final ScaleDecorator sd = new ScaleDecorator();
> window.getDecorators().add( sd );
> sd.setHorizontalAlignment( HorizontalAlignment.LEFT );
> sd.setVerticalAlignment( VerticalAlignment.TOP );
> sd.setScale( 2.0f );
> sd.update();
> window.open(display);
> textPane.requestFocus();
> }
> The program UI will scale correctly the but buttons will react from wrong
> locations.
> There is a issue report in the pivot-user mailing list archives: March 2015
> with the same header as well with more information.
