NAME

Tickit::Widget::FloatBox - manage a collection of floating widgets

SYNOPSIS

TODO

DESCRIPTION

This container widget maintains a collection of floating widgets that can be displayed over the top of a single base widget. The box itself is entirely occupied by the base widget, and by default when no floats are created or displayed it will behave essentially invisibly, as though the box were not there and the base widget was an immediate child of the container the floatbox is inside.

CONSTRUCTOR

$floatbox = Tickit::Widget::FloatBox->new( %args )

Constructs a new Tickit::Widget::FloatBox object.

Takes the following named arguments in addition to those taken by the base Tickit::ContainerWidget constructor.

base_child => Tickit::Widget

The main Tickit::Widget instance to use as the base.

ACCESSORS

$base_child = $floatbox->base_child

$floatbox->set_base_child( $base_child )

Returns or sets the base widget to use.

$float = $floatbox->add_float( %args )

Adds a widget as a floating child and returns a new Float object. Takes the following arguments:

child => Tickit::Widget

The child widget

top, bottom, left, right => INT

The initial geometry of the floating area. These follow the same behaviour as the move method on the Float object.

FLOATS

The following objects represent a floating region as returned by the add_float method.

$child = $float->child

Returns the child widget in the region.

$float->move( %args )

Redefines the area geometry of the region. Takes arguments named top, bottom, left and right, each of which should either be a numeric value, or undef.

The region must have at least one of top or bottom and at least one of left or right defined, which will then fix the position of one corner of the region. If the size is not otherwise determined by the geometry, it will use the preferred size of the child widget. Any geometry argument may be negative to count backwards from the limits of the parent.

For example,

# top-left corner
$float->move( top => 0, left => 0 )

# top-right corner
$float->move( top => 0, right => -1 )

# bottom 3 lines, flush left
$float->move( left => 0, top => -3, bottom => -1 )

Any arguments not passed will be left unchanged; to specifically clear the current value pass a value of undef.

$float->remove

Removes the float from the FloatBox.

TODO

  • Allow floats to be hidden and shown again.

  • Support adjusting stacking order of floats.
