Events #
| Definition | Description |
|---|---|
| AddMarker( MarkerPosition as Integer, byRef MarkerColor as Color ) | When a marker is added to the display by the user, this event will fire with the relevant information. |
| DebugDrawTime( intSeconds as Double ) | This event fires after each redraw of the display as a means of determining how long these redraws take, and can be used to troubleshoot speed issues. |
| MarkerClick( Marker as GSColor ) | This event fires when the user clicks a color marker on the display. |
| MarkerDrag( Marker as GSColor, PreviousPosition as Integer ) | Fired when the user is performing a drag operation on a marker. |
| MarkerMoved( Marker as GSColor, PreviousPosition as Integer ) | Fires when the user has released the mouse after a drag operation. |
| MarkerRemoved( Marker as GSColor, PreviousPosition as Integer ) | Fires when the user drags a marker from the display, removing it. |
| MarkerScaleChanged( Marker as GSColor, PreviousScale as Integer ) | Fires the user has changed the gradient scale for the specified marker. |

| AddValue | newValue as GSColor | None | Used to add a new color to the display at a specified position and with a specified scale. |
| DeleteAll() | None | None | Removes all colors from the display. |
| DeleteValue | intIndex as Integer | None | Removes a color from the display by index or object. |
| DeleteValue | thisValue as GSColor | None | Removes a color from the display by index or object. |
| FindMarker | Marker as GSColor | Integer | Find a value within the array of color values by the specified criteria. |
| FindMarker | MarkerValue as Color MarkerPosition as Integer | None | Find a value within the array of color values by the specified criteria. |
| FromBrush | brush as GraphicsBrush | None | Parses a Linear or RadialGraphicsBrush object to populate the control. |
