Tickit::Widget::LinearBox - abstract base class for
It maintains an ordered list of child widgets, and implements the following child widget options:
- expand => NUM
A number used to control how extra space is distributed among child widgets, if the window containing this widget has more space available to it than the children need. The actual value is unimportant, but extra space will be distributed among the children in proportion with their
For example, if all the children have a
expandvalue of 1, extra space is distributed evenly. If one child has a value of 2, it will gain twice as much extra space as its siblings. Any child with a value of 0 will obtain no extra space.
- force_size => NUM
If provided, forces the size of this child widget, overriding the value returned by
$widget = Tickit::Widget::LinearBox->new( %args )
Returns a new
Takes the following named argmuents:
- children => ARRAY[Tickit::Widget]
@children = $widget->children
In scalar context, returns the number of contained children. In list context, returns a list of all the child widgets.
%opts = $widget->child_opts( $child_or_index )
Returns the options currently set for the given child, specified either by reference or by index.
$widget->set_child( $index, $child )
Replaces the child widget at the given index with the given new one; preserving any options that are set on it.
$widget->set_child_opts( $child_or_index, %newopts )
Sets new options on the given child, specified either by reference or by index. Any options whose value is given as
undef are deleted.
$widget->add( $child, %opts )
Adds the widget as a new child of this one, with the given options.
This method returns the container widget instance itself making it suitable to use as a chaining mutator; e.g.
my $container = Tickit::Widget::LinearBox->new( ... ) ->add( Tickit::Widget::Static->new( ... ) ) ->add( Tickit::Widget::Static->new( ... ) );
This should be preferred over using the
children constructor argument, which is now discouraged.
$widget->add_children( @children )
Adds each of the given widgets as a new child of this one, with no additional options.
This method returns the container widget instance itself making it suitable to use as a chaining mutator.
$widget->remove( $child_or_index )
Removes the given child widget if present, by reference or index
