Prima::ComboBox - standard combo box widget
use Prima::ComboBox;
my $combo = Prima::ComboBox-> create( style => cs::DropDown, items => [ 1 .. 10 ]);
$combo-> style( cs::DropDownList );
print $combo-> text;
Provides a combo box widget which consists of an input line, list box of possible selections and eventual drop-down button. The combo box can be either in form with a drop-down selection list, that is shown by the command of the user, or in form when the selection list is always visible.
The combo box is a grouping widget, and contains neither painting nor user-input code. All such functionality is delegated into the children widgets: input line, list box and button. Prima::ComboBox exports a fixed list of methods and properties from namespaces of Prima::InputLine and Prima::ListBox. Since, however, it is possible to tweak the Prima::ComboBox ( using its editClass and listClass create-only properties ) so the input line and list box would be other classes, it is not necessarily that all default functionality would work. The list of exported names is stored in package variables %listProps, %editProps and %listDynas. These also described in "Exported names" section.
The module defines cs:: package for the constants used by style property.
If 1, adjusts the height of the widget automatically when its font changes. Only when style is not cs::Simple.

Selects whether the combo box user input routine assume that the listbox contains literal strings, that can be fetched via get_item_text ( see Prima::Lists ). As an example when this property is set to 0 is Prima::ColorComboBox from Prima::ComboBox package.
Default value: 1
Selected one of three styles:
The listbox is always visible, and the drop-down button is not.
The listbox is not visible, but the drop-down button is. When the use presses the drop-down button, the listbox is shown; when the list-box is defocused, it gets hidden.
Same as cs::DropDown, but the user is restricted in the selection: the input line can only accept user input that is contained in listbox. If literal set to 1, the auto completion feature is provided.
Mapped onto the edit widget's text property.
Triggered with ComboBox value is changed.
ComboBox forwards SelectItem and DrawItem events from the list box, and these are executed in the List's context (therefore $self there is not ComboBox, but the ComboBox->List). If you use SelectItem you probably need Change instead.
