Layout::Manager::Flow(3pm) User Contributed Perl Documentation Layout::Manager::Flow(3pm) NAME
Layout::Manager::Flow - Directional layout manager DESCRIPTION
Layout::Manager::Flow is a layout manager that anchors components in one of the four cardinal directions. When you instantiate a Flow manager, you may supply it with an anchor value which may be one of north, south, east or west. The example below shows how the default anchor value of north works when you add two components. north +--------------------------------+ | component 1 | +--------------------------------+ | component 2 | +--------------------------------+ | | | | | | +--------------------------------+ Components are placed in the order they are added. If two items are added with a 'north' anchor then the first item will be rendered above the second. Components will be expanded to take up all space perpendicular to their anchor. North and south will expand widths while east and west will expand heights. Flow is similar to Java's FlowLayout <http://java.sun.com/docs/books/tutorial/uiswing/layout/flow.html>. It does not, however, center components. This features may be added in the future if they are needed. SYNOPSIS
$cont->add_component($comp1); $cont->add_component($comp2); my $lm = Layout::Manager::Flow->new(anchor => 'north'); $lm->do_layout($cont); ATTRIBUTES
anchor The direction this manager is anchored. Valid values are north, south, east and west. used Returns the amount of space used an arrayref in the form of "[ $width, $height ]". wrap If set to a true value, then component will be 'wrapped' when they do not fit. This currently only works for East and West anchored layouts. METHODS
do_layout Size and position the components in this layout. AUTHOR

Graphics::Primitive::Container(3pm) User Contributed Perl Documentation Graphics::Primitive::Container(3pm) NAME
Graphics::Primitive::Container - Component that holds other Components DESCRIPTION
Containers are components that contain other components. They can also hold an instance of a Layout::Manager for automatic layout of their internal components. See the Component's Lifecycle Section for more information. SYNOPSIS
my $c = Graphics::Primitive::Container->new( width => 500, height => 350, layout_manager => Layout::Manager::Compass->new ); $c->add_component($comp, { meta => 'data' }); METHODS
Constructor new Creates a new Container. Instance Methods add_component ($component, [ $constraint ]) Add a component to the container. Returns a true value if the component was added successfully. A second argument may be required, please consult the POD for your specific layout manager implementation. Before the component is added, it is passed to the validate_component method. If validate_component does not return a true value, then the component is not added. clear_components Remove all components from the layout manager. component_count Returns the number of components in this container. component_list Returns this Container's ComponentList. find_component Returns the index of the first component with the supplied name. Returns undef if no component with that name is found. get_component Get the component at the specified index. get_constraint Get the constraint at the specified index. get_tree Returns a Forest::Tree object with this component at the root and all child components as children. Calling this from your root container will result in a tree representation of the entire scene. prepare Prepares this container. Does not mark as prepared, as that's done by the layout manager. remove_component Removes a component. Components must have names to be removed. Returns an arrayref of removed components. validate_component Optionally overridden by an implementation, allows it to deem a component as invalid. If this sub returns false, the component won't be added. AUTHOR
