|
50 \brief A button widget to be used in touch keypads. |
|
51 |
|
52 Expands HbPushButton functionality to suit touch keypad purposes. It handles virtual keyboard closing gesture |
|
53 that is initiated from within the button area and knows how to act as a sticky input button. Sticky buttons propagate |
|
54 mouse press state to neighboring button when a drag event crosses widget boundary. This is needed for example in virtual qwerty where |
|
55 user must be able to slide finger across the keyboard. |
