Property Documentation

DeltaY

double Luciad.Input.ScrollEvent.DeltaY

get

The vertical scroll amount and direction.

[get]

Returns the vertical scroll amount and direction. A positive value indicates scrolling up, a negative value indicates scrolling down.

A delta of 1.0 (or -1.0) should be interpreted as follows:

• for mouse wheels, this would correspond to 1 tick, typically 15 degrees of rotation
• for other devices, this would correspond to 10 pixels (device independent pixels)

Location

Luciad.Cartesian.Coordinate Luciad.Input.ScrollEvent.Location

get

The position of the event.

[get]

Returns the position of the event. It is expressed in device independent pixel coordinates with top-left corner of the map being the (0,0) position.

ModifierKeys

Luciad.Input.ModifierKeys Luciad.Input.ScrollEvent.ModifierKeys

get

The modifiers of the event.

[get]

Returns the modifiers of the event.
