/**
|
|
* @short Time period entry widget.
|
|
*
|
|
* The TimePeriod class provides a widget for entering a time period as a number of
|
|
* weeks, days, hours and minutes, or minutes.
|
|
*
|
|
* It displays a combo box to select the time units (weeks, days, hours and minutes, or
|
|
* minutes) alongside a spin box to enter the number of units. The type of spin box
|
|
* displayed alters according to the units selection: day, week and minute values are
|
|
* entered in a normal spin box, while hours and minutes are entered in a time spin box
|
|
* (with two pairs of spin buttons, one for hours and one for minutes).
|
|
*
|
|
* The widget may be set as read-only. This has the same effect as disabling it, except
|
|
* that its appearance is unchanged.
