NAME ^

FLTK::Rectangle - Base class for Widgets, Windows, Monitors, and just about everything else you can see

Description ^

TODO

Functions ^

b

my $b = $rectangle->b( );

Returns y( ) + h( ), the bottom edge of the rectangle.

baseline_y

my $baseline = $rectangle->baseline_y( );

Where to put baseline to center current font nicely.

center_x

my $x = $rectangle->center_x( );

Integer center position. Rounded to the left if w( ) is odd.

center_y

my $y = $rectangle->center_y( );

Integer center position. Rounded to lower y if h( ) is odd.

contains

my $can_has = $rectangle->contains( $x, $y );

True if rectangle contains the pixel who's upper-left corner is at $x, $y.

empty

my $empty = $rectangle->empty( );

True if w( ) or h( ) are less or equal to zero.

h

my $h = $rectangle->h( );

Distance between top and bottom edges.

$rectangle->h( $value );

Change h( ) by moving the bottom edge. y( ) does not change.

inset

$rectangle->inset( $d );

Move all edges in by $d. See also Symbol::inset( ).

intersect

$rectangle->intersect( $r );

merge

$rectangle->merge( $r );

move

$rectangle->move( $x, $y );

Move entire rectangle by given distance in $x and $y.

move_b

$rectangle->move_b( $d );

Add $d to b( ) and h( ).

move_r

$rectangle->move_r( $d );

Add $d to r( ) and w( ).

move_x

$rectangle->move_x( $d );

Add $d to x( ) without changing r( ) (it reduces w( ) by $d).

move_y

$rectangle->move_y( $d );

Add $d to y( ) without changing b( ) (it reduces h( ) by $d).

new

my $self = $rectangle->new( );

This constructor does not put anything into the fields! You can either call set( ) or just modify the x, y, w, and h variables directly.

my $self = $rectangle->new( $x, $y, $w, $h );

Constructor that sets x( ), y( ), w( ), and h( ).

my $self = $rectangle->new( $w, $h );

Constructor that sets x( ) and y( ) to zero, and sets w( ) and h( ).

my $clone = $rectangle->new( $original );

Copy constructor.

my $clone = $rectangle->new( $original, $w, $h, $flags );

Constructor that calls set( ).

not_empty

my $not_empty = $rectangle->not_empty( );

Not exactly the same as !empty(). Returns true if w( ) and h( ) are both greater than zero.

r

my $r = $rectangle->r( );

Returns x( ) + w( ), the right edge of the rectangle.

set

$rectangle->set( $x, $y, $w, $h );

Set x( ), y( ), w( ), h( ) all at once.

$rectangle->set( $rect, $w, $h, $flags );

Sets x, y, w, h so that's it's centered or aligned (if $flags != 0) inside the source $rect.

set_b

$rectangle->set_b( $v );

Change b( ) without changing y( ), by changing the height.

set_r

$rectangle->set_r( $v );

Change r( ) without changing x( ), by changing the width.

set_x

$rectangle->set_x( $v );

Change x( ) without changing r( ), by changing the width.

set_y

$rectangle->set_y( $v );

Change y( ) without changing b( ), by changing the height.

w

my $w = $rectangle->w( );

Distance between left and right edges.

$rectangle->w( $value );

Change w( ) by moving the right edge. x( ) does not change.

x

my $x = $rectangle->x( );

Left edge.

$rectangle->x( $value );

Move the rectangle so that the left edge is at $value.

y

my $y = $rectangle->y( );

Top edge.

$rectangle->y( $value );

Move the rectangle so that the top edge is at $value.
