Click input manipulator recognizes the click and tap gestures from the incoming touch events.
The click manipulator generates the messages required to implement the logic for UI elements that users can click or tap. For example, use the input manipulator to create a button.
To receive the click event, add a message handler for the ClickMessage message.
First create a handler method:
Then add a message handler for your node:
To configure the click manipulator to work together with the multi-click manipulator, you need to configure the click manipulator to wait for the failure of the multi-click:

static |
Message type for notifying recognition of click gesture.
Kanzi generates a click message when the user releases a tracked touch over an attached node, or when the fail manipulator fails.
|
static |
Message type that you can use to notify the beginning of a click gesture.
Kanzi generates the ClickBeginMessage in these cases:
|
static |
Message type for notifying cancellation of click gesture.
Click gesture is canceled when the tracked touch is released outside the node area, or when the fail manipulator succeeds (see InputManipulator::requireToFail).
|
static |
Message type for notifying the tracked touch entering the node area.
Click enter message is generated when touch is pressed over the node area or when the touch returns to the node area after leaving it.
|
static |
Message type for notifying the tracked touch leaving the node area.
Click leave message is generated when the pointer leaves the area or when the click gesture is completed or canceled.
