HildonPickerButton is a widget that lets the user select a particular item from a list. Visually, it's a button with title and value labels that brings up a HildonPickerDialog. The user can then use this dialog to choose an item, which will be displayed in the value label of the button.
You should create your own HildonTouchSelector at convenience and set it
to the HildonPickerButton with hildon_picker_button_set_selector(). For
the common use cases of buttons to select date and time, you can use HildonDateButton
and HildonTimeButton.
Example 15.
