|
51 \brief HbTapGesture is an extension to Qt standard QTapGesture. |
|
52 |
|
53 HbTapGesture extends QTapGesture with additional information related |
|
54 to the tap gesture, but most important use for HbTapGesture is |
|
55 in widgets needing both tap and tap-and-hold. HbTapGesture |
|
56 provides both -- use of Qt::TapAndHoldGesture |
|
57 in conjunction with Qt::TapGesture in the same widget makes it |
|
58 difficult to handle state updates and finishes in the widget. |
|
59 HbTapGesture::tapStylehint() can be used to query whether |
|
60 the tap was a normal tap, or tap-and-hold at the time of Qt::GestureUpdated |
|
61 of Qt::GestureFinished. A gesture update will be sent at the time |
|
62 when the tap-and-hold timer triggers. No updates are sent |
|
63 of the finger movement during the tap. |
