inlineoverridevirtual

Set the control's value from the delegate This method is called from the class implementing the IEditorDelegate interface in order to update a control's value members and set it to be marked dirty for redraw.

Parameters
valueNormalised incoming value
valIdxThe index of the value to set, which should be between 0 and NVals()

Reimplemented from IControl.

inlineoverridevirtual

Set the control's value after user input.

This method is called after a text entry or popup menu prompt triggered by PromptUserInput(), calling SetDirty(true), which will mean that the new value gets sent back to the delegate

Parameters
valuethe normalised value after user input via text entry or pop-up menu
valIdxAn index to choose which of the controls linked parameters to retrieve. NOTE: since controls usually have only 1 parameter you can omit this argument and use the default index of 0
