Detailed Description

The event holds a pointer event data and typically originates from a mouse or other pointing device.

It holds the coordinates of the event as well as the buttons pressed, the wheel scrolling distance, and the state.

The type of the event is InputEvent::Pointer.

Constructor & Destructor Documentation

◆ PointerEvent()

kanzi::PointerEvent::PointerEvent ( int x,
int y,
PointerButton buttons,
PointerState state,
int scroll = 0 )
explicit

Creates a PointerEvent for the (x, y) coordinates with the buttons, scroll, and state.

Parameters
xThe x axis coordinate of the pointer event.
yThe y axis coordinate of the pointer event.
buttonsThe buttons set for the pointer event. See PointerButton.
stateThe state of the event.
scrollThe amount scrolled. Does not depend on the state of the event.
Since
Kanzi 3.8.0 the buttons argument is of type PointerButton.

Member Function Documentation

◆ getX()

int kanzi::PointerEvent::getX ( ) const
inline

Returns the x axis coordinate of the pointer event.

◆ getY()

int kanzi::PointerEvent::getY ( ) const
inline

Returns the y axis coordinate of the pointer event.

◆ getButtons()

PointerButton kanzi::PointerEvent::getButtons ( ) const
inline

Returns the buttons of the pointer event.

Returns
The buttons of the pointer event.
Since
Kanzi 3.8.0 return type is PointerButton.

◆ getScroll()

int kanzi::PointerEvent::getScroll ( ) const
inline

Returns the scroll distance of the pointer event.

Returns
The scroll distance, indicating the distance the wheel is rotated. Positive value indicates forward rotation. Negative value indicates backward rotation.

◆ getState()

PointerState kanzi::PointerEvent::getState ( ) const
inline

Returns the state of the pointer event.

◆ transform()

UniqueEventPtr kanzi::PointerEvent::transform ( const Matrix3x3 & transformationMatrix) const

Transforms the pointer event using the given transformationMatrix.

Parameters
transformationMatrixThe transformation matrix to apply to the pointer.
Returns
The unique pointer to the transformed pointer event.

◆ hasButton()

bool kanzi::PointerEvent::hasButton ( PointerButton button) const
inline

Checks whether the given button is set on the pointer event.

Parameters
buttonThe pointer button to check.
Returns
true if the button is set, false otherwise.

◆ hasButtonWithState()

bool kanzi::PointerEvent::hasButtonWithState ( PointerButton button,
PointerState state ) const
inline

Checks whether the given button is set for the given state.

Parameters
buttonThe pointer button to check.
stateThe state of the pointer.
Returns
true if the button is set, false otherwise.

◆ getPoint()

Vector2 kanzi::PointerEvent::getPoint ( ) const
inline

Returns a Vector2 representation of the touch point.

Returns
The Vector2 with the touch point.
Since
Kanzi 3.9.0
