These define the value of the tooltip display on KineticaRT.Studio controls.
The tooltip is displayed to the user when the mouse is placed above a control and then not moved for a few seconds. It is normally used in KineticaRT Studio to give a full description of the channel that the control is connected to since there is normally not enough space for more than the channel name to be permanently displayed on the screen.
If the ToolTipSource property is set to Custom then the control will display the value entered in the CustomToolTip property, if it is set to Description it will take its value from the connected channels Description property and if set to ToolTip it will take its value from the connected channels Tooltip property.
The value in the Tooltip property is the value being used, it cannot be changed directly.
