METHODS
new
Instantiate a new tabbed window.
Takes the following named parameters:
tab_position - (optional) location of the tabs, should be one of left, top, right, bottom.
tab_position
Accessor for the tab position (top, left, right, bottom).
active_tab_index
Returns the 0-based index of the currently-active tab.
active_tab
Returns the currently-active tab as a tab object. See below.
active_tab_widget
Returns the widget in the currently active tab.
add_tab
Add a new tab to this tabbed widget. Returns an object representing the tab; see "METHODS ON TAB OBJECTS" below.
First parameter is the widget to use.
Remaining form a hash:
remove_tab
Remove tab given by 0-based index or tab object.
move_tab
Move tab given by 0-based index or tab object forward the given number of positions.
activate_tab
Switch to the given tab; by 0-based index, or object.
next_tab
Switch to the next tab. This may be bound as a key action.
prev_tab
Switch to the previous tab. This may be bound as a key action.
METHODS ON TAB OBJECTS
The following methods may be called on the objects returned by add_tab or active_tab.
index
Returns the 0-based index of this tab
widget
Returns the Tickit::Widget contained by this tab
label
Returns the current label text
set_label
Set new label text for the tab
is_active
Returns true if this tab is the currently active one
activate
Activate this tab
set_on_activated
Set a callback or method name to invoke when the tab is activated
set_on_deactivated
Set a callback or method name to invoke when the tab is deactivated
pen
Returns the Tickit::Pen used to draw the label.
Pen observers are no longer registered on the return value; to set a different pen on the tab, use the set_pen method instead.
CUSTOM TAB CLASS
Rather than use the default built-in object class for tab objects, a Tickit::Widget::Tabbed or subclass thereof can return objects in another class instead. This is most useful for subclasses of the tabbed widget itself.
To perform this, create a subclass of Tickit::Widget::Tabbed::Tab. Since version 0.022 this module is implemented using Object::Pad, so you can rely on having that available for implementing a subclass:
use Object::Pad;
class MyCustomTabClass extends Tickit::Widget::Tabbed::Tab;Arrange for this class to be used by the tabbed widget either by passing its name as a constructor argument called tab_class, or by overriding a method called TAB_CLASS.
my $tabbed = Tickit::Widget::Tabbed->new(
tab_class => "MyCustomTabClass"
);or
use constant TAB_CLASS => "MyCustomTabClass";CUSTOM RIBBON CLASS
Rather than use the default built-in object class for the ribbon object, a Tickit::Widget::Tabbed or subclass thereof can use an object in another subclass instead. This is most useful for subclasses of the tabbed widget itself.
For more detail, see the documentation in Tickit::Widget::Tabbed::Ribbon.
