Gigasoft.ProEssentials.Pe3do.PeUserInterface.Scrollbar Members

DegreeOfRotation

Gets or Sets the current horizontal scroll bar position (0 - 359 degrees) controlling horizontal image rotation. NOTE: Only set this property after the control is initialized via one of the Functions.Reinitialize.. functions.

HorzScrollBar

Gets or Sets whether a horizontal scrollbar will be visible. The horizontal scroll bar controls the rotation angle of image. Scrollbar.DegreeOfRotation programmatically controls this angle.

MouseDraggingX

Gets or Sets whether user can click, grab and drag the chart via the mouse in horizontal direction. The horizontal scrollbar must be visible for this feature to function.

MouseDraggingY

Gets or Sets whether user can click, grab and drag the chart via the mouse in vertical direction. The vertical scrollbar must be visible for this feature to function.

MouseWheelZoomFactor

Controls a logical zoom/unzoom adjustment per notch on mouse wheel. Allows controlling the rate at which the data is zoomed via the mouse wheel. Default 1.0 and likely useful range is 3.0 to .03.

MouseWheelZoomSmoothness

Set to force additional n image updates and thus animates the transition of zoom via mouse wheel. We recommend a value 6 for good mix of performance and smoothness. Direct3D RenderEngine can support larger values. Set to values between 2 to 40. Set to 0 to disable.

PinchZoomFactor

Controls a logical zoom/unzoom adjustment per pinch gesture message/event. Allows controlling the rate at which the data is zoomed via the pinch gesture. Default 1.0 and likely useful range is 3.0 to .03.

PinchZoomSmoothness

Set to force additional n image updates and thus animates the transition of zoom via pinch touch gesture. We recommend a value 2 or 3 for good mix of performance and smoothness. There are inheriently more default pinch events/updates as compared to mouse wheel zoom events so a smaller value is best. Direct3D RenderEngine can support larger values. Set to 0 to disable.

ScrollSmoothness

Set to force additional n image updates and thus animates the rotating from one DegreeOfRotation to next. Also effects ViewingHeight rotation. We recommend a value 6 for good mix of performance and smoothness. Direct3D RenderEngine can support larger values if preferred. Set to 0 to disable.

VertScrollBar

Gets or Sets whether a vertical scrollbar will be visible. The vertical scroll bar controls the viewing height of image. Scrollbar.ViewingHeight programmatically controls this scroll bar position.

ViewingHeight

Gets or Sets the current vertical scroll bar position controlling vertical image rotation. Possible values range from 50 through 50. Where 50 is looking above 3d image. NOTE: Only set this property after the control is initialized via one of the Functions.Reinitialize.. functions.
