History of 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>
