= setCtlTicFreq =

== Syntax ==
{{int setCtlTicFreq(int n, int m)}}

== Arguments ==
:'''n'''
::The index of the trackbar control to change.
:'''m'''
::The interval between tick marks.

== Return ==
Returns true / 1 if the function succeed. Returns -1 if the control number is out of range or not in use. Returns false if the control is not a ((TRACKBAR)) or ((SLIDER)) control.

== Description ==
Sets the frequency with which tick marks are displayed for slider control n. For example, if the frequency is set to 2, a tick mark is displayed for every other increment in the slider’s range. The default setting for the frequency is 1 (that is, every increment in the range is associated with a tick mark).

== Comments ==
The ((SLIDER)) or ((TRACKBAR)) must have the AUTOTICKS style set for this function to work.

== Example ==
<code>
%fml
ctl[0]: TRACKBAR(AUTOTICKS), Range=(0,100)

OnFilterStart: {
  // Set a tick mark at 20, 40, 60 etc.
  setCtlTicFreq(0, 20);
  return true;
}
</code>
