InheritedProtected
Animation | public | Specifies whether to customize inertial scrolling by taking into account the DecelerationRate property when calculating parameters of inertial scrolling. |
AutoShowing | public | Enables the smooth hiding and showing of scroll bars. |
Averaging | public | Specifies whether to average an inertial moving velocity taking into account all existing points on a trajectory. |
BoundsAnimation | public | Determines whether a corner of the scrolling viewport can be dragged inside the visible area. |
CancelTargetX | protected | Defines whether inertial scrolling is impossible in the horizontal direction. |
CancelTargetY | protected | Defines whether inertial scrolling is impossible in the vertical direction. |
CurrentVelocity | public | The current velocity of the inertial moving of a scroll view in pixels per second. |
DeadZone | protected | Defines the size of an area where moving of the finger (or mouse) does not initialize scrolling. |
DecelerationRate | public | Determines the deceleration rate of inertial scrolling. |
Disposed | protected | Disposed is a read-only property that shows the current state of this object. |
Down | public | Specifies that the user has pressed a mouse button or has touched the touch screen. |
Elasticity | public | The coefficient of border elasticity. |
Enabled | protected | Specifies whether the inertial moving of the scroll view is enabled. |
InternalTouchTracking | protected | Defines the possible inertial moving directions initiated by the touch tracking. |
Interval | public | Defines the interval between successive updates of the pictures of the inertial moving. |
InTimerProc | public | InTimerProc is set to True when the inertial scrolling engine starts a timer during calculations of inertial moving parameters. |
LastTimeCalc | public | The last moment when any of the ViewportPosition or CurrentVelocity properties was calculated. |
LowVelocity | public | Returns whether the current velocity (CurrentVelocity) is lower than the minimal permitted velocity (MinVelocity) of the inertial moving of a scroll view in pixels per second. |
MaxTarget | protected | Defines the maximal coordinates that can be accepted by the viewport position (viewport origin). |
MaxVelocity | protected | The maximal permitted velocity of the inertial moving of a scroll view in pixels per second. |
MinTarget | protected | Defines the minimal coordinates that can be accepted by the viewport position (viewport origin). |
MinVelocity | protected | The minimal permitted velocity of the inertial moving of a scroll view in pixels per second. |
MouseTarget | protected | A target point specified by rotating the mouse wheel MouseWheel. |
Moved | public | Determines whether the mouse is pressed and moved or the finger is moved. |
Opacity | public | The current opacity of the scroll bars. |
PositionCount | protected | The number of TPointD positions stored in the Positions array. |
Positions | protected | Array of TPointD positions. |
PositionTimes | protected | Array of times corresponding to Positions. |
Shown | protected | Specifies whether the scroll bars (scroll indicators) are shown. |
StorageTime | public | The duration of time in which the scrolling engine stores obtained trajectory points. |
Target | protected | The current target point. |
TargetCount | public | The number of target points stored in the array that is retrieved by GetTargets. |
TouchTracking | public | Defines the possible directions of the inertial scrolling initiated by the touch input. |
UpdateCount | public | Keeps the number of calls to BeginUpdate that have not been followed by calls to EndUpdate. |
UpDownTime | protected | Keeps the last moment when the mouse (or finger) was pressed down or released (got up). |
UpPosition | protected | Identifies the position where the mouse button was released. |
UpVelocity | protected | Identifies the velocity at the moment when the mouse button was released. |
ViewportPosition | public | Coordinates of the origin of the scrolling viewport specified as the offset from the origin of the content layout of this scroll component. |
ViewportPositionF | public | Coordinates of the origin of the scrolling viewport specified as the offset from the origin of the scroll component. |
