Specify a user-defined scale.

By default, the widget is supposed to control the range of its scale automatically, but sometimes it is desirable to have a user-defined scale which is not in sync with the widget's range, e.g. if a logarithmic scale is needed (sliders don't support that) or if the scale is required to have a fixed range (say 0...100%), independent of the widget's range.

Parameters: vmin

vmax interval boundaries

step major step size

logarithmic If != 0, build a logarithmic scale

Set the maximum number of major tick intervals.

The scale's major ticks are calculated automatically such that the number of major intervals does not exceed ticks. The default value is 5.

Parameters: ticks maximal number of major ticks.
