Detailed Description

Describes the mouse wheel event.

Definition at line 21 of file wheelhandler.h.

Property Documentation

accepted

bool KirigamiWheelEvent::accepted

readwrite

accepted: bool

If set, the event shouldn't be managed anymore, for instance it can be used to block the handler to manage the scroll of a view on some scenarios

// This handler handles automatically the scroll of
// flickableItem, unless Ctrl is pressed, in this case the
// app has custom code to handle Ctrl+wheel zooming
Kirigami.WheelHandler {
  target: flickableItem
  blockTargetWheel: true
  scrollFlickableTarget: true
  onWheel: {
       if (wheel.modifiers & Qt.ControlModifier) {
           wheel.accepted = true;
           // Handle scaling of the view
      }
  }
}

Definition at line 106 of file wheelhandler.h.

angleDelta

QPointF KirigamiWheelEvent::angleDelta

read

angleDelta: point

The distance the wheel is rotated in degrees. The x and y coordinates indicate the horizontal and vertical wheels respectively. A positive value indicates it was rotated up/right, negative, bottom/left This value is more likely to be set in traditional mice.

Definition at line 47 of file wheelhandler.h.

buttons

int KirigamiWheelEvent::buttons

read

buttons: int

it contains an OR combination of the buttons that were pressed during the wheel, they can be: Qt.LeftButton, Qt.MiddleButton, Qt.RightButton

Definition at line 62 of file wheelhandler.h.

inverted

bool KirigamiWheelEvent::inverted

read

inverted: bool

Whether the delta values are inverted On some platformsthe returned delta are inverted, so positive values would mean bottom/left

Definition at line 81 of file wheelhandler.h.

modifiers

int KirigamiWheelEvent::modifiers

read

modifiers: int

Keyboard mobifiers that were pressed during the wheel event, such as: Qt.NoModifier (default, no modifiers) Qt.ControlModifier Qt.ShiftModifier ...

Definition at line 73 of file wheelhandler.h.

pixelDelta

QPointF KirigamiWheelEvent::pixelDelta

read

pixelDelta: point

provides the delta in screen pixels available on high resolution trackpads

Definition at line 54 of file wheelhandler.h.

x

qreal KirigamiWheelEvent::x

read

x: real

X coordinate of the mouse pointer

Definition at line 30 of file wheelhandler.h.

y

qreal KirigamiWheelEvent::y

read

y: real

Y coordinate of the mouse pointer

Definition at line 37 of file wheelhandler.h.
