bug: https://bugs.openjdk.java.net/browse/JDK-8091832
webrev: http://cr.openjdk.java.net/~flar/JDK-8091832/webrev.rt.00/
This webrev fixes pixel snapping and application control over pixel
scaling on HiDPI screens:
- snap*() methods are all updated to take the current scale into account
- new variants of snap*() methods are added for separate X/Y control:
Added: Region.snapSpaceX/Y()
Added: Region.snapSizeX/Y()
Added: Region.snapPositionX/Y()
- the non-X/Y variants of the above methods are now deprecated:
Deprecated: Region.snapSpace()
Deprecated: Region.snapSize()
Deprecated: Region.snapPosition()
- methods to query the scale values of Screen objects:
Added: Screen.getOutputScaleX/Y()
- properties to query and/or modify the scale values of Window objects:
Added Read-Only DoubleProperty: Window.getOutputScaleX/Y()
Added Read-Write BooleanProperty:
Window.set/getForceIntegerRenderScale()
Added Read-Write DoubleProperty: Window.set/getRenderScaleX/Y()
The changes have been compiled and tested on Windows and Mac and there
were trivial changes needed to the Linux files to adapt to one new
method signature, but I haven't done the test build on Linux yet...
