Property Documentation
[read-only] boundingBox : rect |
Bounding box for the trace input.
This property is readonly and is automatically updated based on the item size and margins.
canvasType : string |
Canvas type of this trace input area.
This property can be used to distinguish between different types of canvases. For example, in full screen handwriting mode this property is set to "fullscreen", and in keyboard handwriting mode this property is set to "keyboard".
horizontalRulers : var |
List of horizontal rulers in the input area.
The rulers are defined as a number of pixels from the top edge of the boundingBox.
Here is an example that demonstrates how to define rulers:
horizontalRulers: [boundingBox.height / 3, boundingBox.height / 3 * 2] verticalRulers: [boundingBox.width / 3, boundingBox.width / 3 * 2]
patternRecognitionMode : int |
Pattern recognition mode of this input area.
The default value is InputEngine.PatternRecognitionMode.None.
verticalRulers : var |
List of vertical rulers in the input area.
The rulers are defined as a number of pixels from the left edge of the boundingBox.
