Prima::ComboBox(3) standard combo box widget

SYNOPSIS


use Prima::ComboBox;
my $combo = Prima::ComboBox-> create( style => cs::DropDown, items => [ 1 .. 10 ]);
$combo-> style( cs::DropDownList );
print $combo-> text;

DESCRIPTION

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.
