Pointer hit areas and paint clip areas are separate concepts, but similar enough to warrant merging. This change replaces pointer hit areas with clip areas, so Gio is left with just one area concept (in package op/clip). The reason for separating the concepts in the original Gio release was because of my being unsure general path/stroke hit areas would ever be implemented, let alone efficient. This change represents a change of mind, in the sense that it's better to have an incomplete API than two separate area concepts. Leave the deprecated pointer.Rect, pointer.Ellipse for temporary backwards compatibility. This is an API change. Most existing programs should continue to build with this change, but may have to adjust to having all clip.Ops participate in InputOp hit areas. Signed-off-by: Elias Naur <mail@eliasnaur.com>

Package clip provides operations for defining areas that applies to operations
|
|
such as paints and pointer handlers.
|
|
|
|
The current clip is initially the infinite set. Pushing an Op sets the clip
|
|
to the intersection of the current clip and pushed clip area. Popping the
|
|
area restores the clip to its state before pushing.
|
|
|
|
General clipping areas are constructed with Path. Common cases such as
|
|
rectangular clip areas also exist as convenient constructors.
