Returns a numerical value indicating the object ID number of the currently active arrow object.
Arw_GetActive returns -1 if no arrow objects are currently selected or were added to a chart yet. If an active arrow drawing object is removed from a chart then Arw_GetActive returns -1. If an inactive arrow drawing object is removed from a chart then Arw_GetActive returns the object ID number of the currently active arrow object.
Usage
Arw_GetActive
Notes
- An object-specific ID number is assigned by Arw_New, Arw_New_s, Arw_New_self or Arw_New_self_s when the arrow object is created.
- Use MC_Arw_GetActive to get the arrow ID number of the currently selected arrow.
Example
Assign a value, indicating the object ID number of the currently selected arrow object, to Value1 variable:
Value1 = Arw_GetActive;
