Re: Review Request JDK-8159168 [hidpi] Window.setShape() works incorrectly on HiDPI

[Semyon Sadetsky]

Hi Rajeev,

The fix itself looks good. I only did not get for what purpose mouse 
pointer is moved in the test?

    Hello Alexandr,

    Thanks for the review.

    As per windows specification X & Y scale are always equal that’s
    why I have put scaleX == scaleY check.

    But it may change in future so I have removed this check.

1135             if (scaleX != 1 && scaleY != 1) {

  It is better to use 'or' operator because the shape should be scaled 
when on of the scales is differ from 1.

Thanks,
Alexandr.

        Hello All,

        Please review the following webrev.

        Bug: https://bugs.openjdk.java.net/browse/JDK-8159168

        Webrev:
        http://cr.openjdk.java.net/~rchamyal/8159168/webrev.00/
        <http://cr.openjdk.java.net/%7Erchamyal/8159168/webrev.00/>

        Issue: In HiDPI screen shape set through window::setShape API
        is not scaled based on system scale.

        Fix:. Updated the WComponentPeer::applyShape to update shape
        based on system scale.

    1131 double scaleX =
    winGraphicsConfig.getDefaultTransform().getScaleX();
    1132             double scaleY =
    winGraphicsConfig.getDefaultTransform().getScaleY();

     The getDefaultTransform() is called twice which leads that
    AffineTransform object is created two times
    1133             if (scaleX != 1 && scaleY != 1 && scaleX == scaleY) {

       Is the check scaleX == scaleY really necessary here?

       Is it possible to make the test automated? Just run it with
    option "@run main/othervm -Dsun.java2d.uiScale=2 TestName" and
    check the area where the shape is drawn?

      Thanks,
      Alexandr.
