New issue 265 by [email protected]: PMouseWheelZoomXYEventHandler : I can
not commit (403 Forbidden)
https://code.google.com/p/piccolo2d/issues/detail?id=265
Hello,
I coded a new class but can not commit it. (403 Forbidden)
Please, would you like to commit it to the SVN.
Thanks,
Nico
Here is the commit message :
* This commit bring a new class, the PMouseWheelZoomXYEventHandler which
is a evolved zoom event handler.
The default behavior is the same as the existing
PMouseWheelZoomEventHandler but 2 other behaviors are available :
-> If the user maintains the "SHIFT" key during mouse wheel motion,
only the X axis will be rescaled.
-> If the user maintains the "ALT" key during mouse wheel motion, only
the Y axis will be rescaled.
NB : With the default behavior, the zoom will be applied on X and Y
axis (as PMouseWheelZoomEventHandler).
* Somes changes are necessary in the following classes :
1) PCamera
--> adding the method
public void scaleViewAboutPoint(final double scaleX, final
double scaleY, final double x, final double y)
--> updating the method
public void scaleViewAboutPoint(final double scale, final double
x, final double y)
2) PMouseWheelZoomEventHandler need to be inheritable.
--> removing the "final class"
--> scaleFactor is now protected
--> private Point2D getViewAboutPoint(final PInputEvent event) is
now protected
3) PAffineTransform
--> the method
public void scaleAboutPoint(final double scaleX, final double
scaleY, final double x, final double y)
has been added.
--> the method
public void scaleAboutPoint(final double scale, final double x,
final double y)
has been modified.
Please note, that all these changes are fully compatible with the
previous version.
