DESCRIPTION

XmScaleSetTicks controls the number, location, and size of the tick marks on a Scale. Each tick mark is a SeparatorGadget oriented perpendicular to the Scale's orientation. For example, if the Scale is oriented horizontally, the tick marks will be oriented vertically.

If you specify tick marks for a Scale and then change the Scale's orientation, you will have to do the following:

  1. Remove all the tick marks. To remove tick marks from a Scale, you must destroy (with XtDestroyChildren) the SeparatorGadget tick marks. The first two children of a Scale are its title and scroll bar, and all additional children are tick marks.

  2. Recreate the tick marks by calling XmScaleSetTicks.

    3. scale
    Specifies the Scale widget ID that is getting the tick marks.

    big_every
    Specifies the number of scale values between big ticks.

    num_medium
    Specifies the number of medium ticks between big values.

    num_small
    Specifies the number of small ticks between medium values.

    size_big
    Specifies the size (either width or height) of the big ticks.

    size_medium
    Specifies the size (either width or height) of the medium ticks.

    size_small
    Specifies the size (either width or height) of the small ticks.

    For a complete definition of Scale and its associated resources, see XmScale (3).
