Touch namespace
Functions
| Function |
Description |
| checkTouchIdentifier(e) |
Check whether the pointer identifier on the event matches the current saved identifier. If the current identifier was unset, save the identifier from the event. This starts a drag/gesture, during which pointer events with other identifiers will be silently ignored. |
| clearTouchIdentifier() |
Clear the touch identifier that tracks which touch stream to pay attention to. This ends the current drag/gesture and allows other pointers to be captured. |
| getTouchIdentifierFromEvent(e) |
Get the pointer identifier from the given event. |
| shouldHandleEvent(e) |
Decide whether Blockly should handle or ignore this event. Mouse and touch events require special checks because we only want to deal with one touch stream at a time. All other events should always be handled. |
Variables
| Variable |
Description |
| TOUCH_ENABLED |
Whether touch is enabled in the browser. Copied from Closure's goog.events.BrowserFeature.TOUCH_ENABLED |
| TOUCH_MAP |
The TOUCH_MAP lookup dictionary specifies additional touch events to fire, in conjunction with mouse events. |
