Graphics::Primitive::Component(3pm) User Contributed Perl Documentation Graphics::Primitive::Component(3pm)
NAME
Graphics::Primitive::Component - Base graphical unit
DESCRIPTION
A Component is an entity with a graphical representation.
SYNOPSIS
my $c = Graphics::Primitive::Component->new({
origin => Geometry::Primitive::Point->new({
x => $x, y => $y
}),
width => 500, height => 350
});
LIFECYCLE
prepare
Most components do the majority of their setup in the prepare. The goal of prepare is to establish it's minimum height and width so
that it can be properly positioned by a layout manager.
$driver->prepare($comp);
layout
This is not a method of Component, but a phase introduced by the use of Layout::Manager. If the component is a container then each of
it's child components (even the containers) will be positioned according to the minimum height and width determined during prepare.
Different layout manager implementations have different rules, so consult the documentation for each for details. After this phase has
completed the origin, height and width should be set for all components.
$lm->do_layout($comp);
finalize
This final phase provides and opportunity for the component to do any final changes to it's internals before being passed to a driver
for drawing. An example might be a component that draws a fleuron at it's extremities. Since the final height and width isn't known
until this phase, it was impossible for it to position these internal components until now. It may even defer creation of this
components until now.
It is not ok to defer all action to the finalize phase. If you do not establish a minimum hieght and width during prepare then the
layout manager may not provide you with enough space to draw.
$driver->finalize($comp);
draw
Handled by Graphics::Primitive::Driver.
$driver->draw($comp);
METHODS
Constructor
new Creates a new Component.
Instance Methods
background_color
Set this component's background color.
border
Set this component's border, which should be an instance of Border.
callback
Optional callback that is fired at the beginning of the "finalize" phase. This allows you to add some sort of custom code that can
modify the component just before it is rendered. The only argument is the component itself.
Note that changing the position or the dimensions of the component will not re-layout the scene. You may have weird results of you
manipulate the component's dimensions here.
class
Set/Get this component's class, which is an abitrary string. Graphics::Primitive has no internal use for this attribute but provides
it for outside use.
color
Set this component's foreground color.
fire_callback
Method to execute this component's "callback".
get_tree
Get a tree for this component. Since components are -- by definiton -- leaf nodes, this tree will only have the one member at it's
root.
has_callback
Predicate that tells if this component has a "callback".
height
Set this component's height.
inside_bounding_box
Returns a Rectangle that defines the edges of the 'inside' box for this component. This box is relative to the origin of the
component.
inside_height
Get the height available in this container after taking away space for padding, margin and borders.
inside_width
Get the width available in this container after taking away space for padding, margin and borders.
margins
Set this component's margins, which should be an instance of Insets. Margins are the space outside the component's bounding box, as in
CSS. The margins should be outside the border.
maximum_height
Set/Get this component's maximum height. Used to inform a layout manager.
maximum_width
Set/Get this component's maximum width. Used to inform a layout manager.
minimum_height
Set/Get this component's minimum height. Used to inform a layout manager.
minimum_inside_height
Get the minimum height available in this container after taking away space for padding, margin and borders.
minimum_inside_width
Get the minimum width available in this container after taking away space for padding, margin and borders.
minimum_width
Set/Get this component's minimum width. Used to inform a layout manager.
name
Set this component's name. This is not required, but may inform consumers of a component. Pay attention to that library's
documentation.
origin
Set/Get the origin point for this component.
outside_height
Get the height consumed by padding, margin and borders.
outside_width
Get the width consumed by padding, margin and borders.
finalize
Method provided to give component one last opportunity to put it's contents into the provided space. Called after prepare.
padding
Set this component's padding, which should be an instance of Insets. Padding is the space inside the component's bounding box, as in
CSS. This padding should be between the border and the component's content.
page
If true then this component represents stand-alone page. This informs the driver that this component (and any children) are to be
renderered on a single surface. This only really makes sense in formats that have pages such as PDF of PostScript.
prepare
Method to prepare this component for drawing. This is an empty sub and is meant to be overridden by a specific implementation.
preferred_height
Set/Get this component's preferred height. Used to inform a layout manager.
preferred_width
Set/Get this component's preferred width. Used to inform a layout manager.
to_string
Get a string representation of this component in the form of:
$name $x,$y ($widthx$height)
visible
Set/Get this component's visible flag.
width
Set/Get this component's width.
