WkDateEditorView
The WkDateEditorView, as its name implies, provides a convenient control for editing dates. It contains three fields for setting the month, day, and year of a date value. Since it is specifically designed for date manipulation, it assures that any date entered is guaranteed valid.
Date editors allow the user to edit a date by manipulating the month, day, and year fields as if they were each numeric editors. When a date widget receives the input focus, the first field becomes the current field. The current field can be selected by using the mouse or the left and right arrow keys. Once selected, a field (day, month, or year) can be edited using either the arrow buttons or by using the keyboard to type the value. Incrementing past the last day in a month or the last month in a year will increment the month or year.
WkDateEditorView provides a variety of styles to allow for flexibility in choosing a date format. These styles mirror the settings dialog provided by Windows, and should allow all supported cultural date variations, including changing the separator (“/” by default), switching the order of the editors, and showing leading zeros or the full century.
The contents of a WkDateEditorView is a Date object, both for setting and retrieving the current value. A user can increment or decrement the values using up/down arrow keys or by selecting the up/down buttons. A user can change the value in an editable spin button by typing in the entry field.
