Detailed Description
Pointer gesture recognizer.
PointerRecognizer is a gesture recognizer that calculates pointer gesture data from given touch events. It is used for generating mouse events from touch events. PointerRecognizer is one of the gesture recognizers handled by GestureContext.

Member Function Documentation
| bool WebCore::PointerRecognizer::altKey | ( | ) | const [inline] |
Get alt key's state.
- Returns:
- true is the alt key is pressed.
Definition at line 18 of file PointerRecognizer.h.
References m_altKey.
| const bool WebCore::PointerRecognizer::cancelled | ( | ) | const [inline] |
Get the cancelled status of the recognizer.
If more than one fingers touch the screen, the recognizer is cancelled and won't give valid mouse pointer data.
- Returns:
- true if the recognizer is cancelled.
Definition at line 23 of file PointerRecognizer.h.
References m_cancelled.
| bool WebCore::PointerRecognizer::ctrlKey | ( | ) | const [inline] |
Get control key's state.
- Returns:
- true is the control key is pressed.
Definition at line 17 of file PointerRecognizer.h.
References m_ctrlKey.
| bool WebCore::PointerRecognizer::metaKey | ( | ) | const [inline] |
Get meta key's state.
- Returns:
- true is the meta key is pressed.
Definition at line 19 of file PointerRecognizer.h.
References m_metaKey.
| const IntPoint & WebCore::PointerRecognizer::pos | ( | ) | const [inline] |
Get the pointer position.
- Returns:
- position of the pointer in client coordinates.
- See also:
- screenPos
Definition at line 13 of file PointerRecognizer.h.
References m_pos.
| void WebCore::PointerRecognizer::reset | ( | ) | [virtual] |
Reset gesture state.
Reimplemented from WebCore::GestureRecognizer.
Definition at line 84 of file PointerRecognizer.cpp.
References m_cancelled.
| const IntPoint & WebCore::PointerRecognizer::screenPos | ( | ) | const [inline] |
Get the pointer position in screen coordinates.
- Returns:
- position of the pointer in screen coordinates.
- See also:
- pos
Definition at line 14 of file PointerRecognizer.h.
References m_screenPos.
| bool WebCore::PointerRecognizer::shiftKey | ( | ) | const [inline] |
Get shift key's state.
- Returns:
- true is the shift key is pressed.
Definition at line 16 of file PointerRecognizer.h.
References m_shiftKey.
| const double WebCore::PointerRecognizer::timestamp | ( | ) | const [inline] |
Get the timestamp of the last event.
- Returns:
- the time of the last processed event, in seconds since some undefined time.
Definition at line 21 of file PointerRecognizer.h.
References m_timestamp.
| void WebCore::PointerRecognizer::touchEvent | ( | const PlatformTouchEvent & | ev | ) | [virtual] |
Handle a platform touch event.
Interpret a touch event and set gesture parameters accordingly.
- Parameters:
-
ev Platform touch event.
Implements WebCore::GestureRecognizer.
