NAME ^

Tk::BarberPole - A rotating barber pole

SYNOPSIS ^

    use Tk::BarberPole;

    $pole = $parent->BarberPole(
        -width       => 200,
        -length      => 20,
        -bg          => 'white',
        -orientation => 'vertical',
        -colors      => [qw/red blue/],

        -slant       => 38,
        -stripewidth => 15,
        -separation  => 35,

        -delay       => 50,
        -autostart   => 1,
    );

    $pole->start;
    $pole->stop;

DESCRIPTION ^

Tk::BarberPole is a widget in the shape of a rotating barber pole. Animation can be started and stopped programatically.

STANDARD OPTIONS ^

The following standard widget options are supported:

-borderwidth

Defaults to 0.

-highlightthickness

Defaults to 0.

-padx

Defaults to 0.

-pady

Defaults to 0.

-relief

Defaults to flat.

WIDGET-SPECIFIC OPTIONS ^

-autostart

If set to a true value, animation of the barber pole automatically starts at widget creation. The animation can be further controlled via the start and stop methods. Defaults to 1.

-colors

Specifies the colors of the stripes. The value must be an anonymous list of the colors. The number of stripes will always be a multiple of the number of colors specified. Defaults to ['red', 'blue'].

-delay

The delay, in milliseconds, between successive updates of the stripe positions. Each update moves the stripes by one pixel. The smaller the delay, the faster the animation. Defaults to 50.

-length

Specifies the desired long dimension of the BarberPole in screen units (i.e. any of the forms acceptable to Tk_GetPixels). For vertical BarberPoles this is the height; for horizontal ones it is the width. Defaults to 100.

-orientation

Specifies the orientation of the BarberPole. Valid values are 'horizontal', and 'vertical'. Defaults to 'horizontal'.

-separation

Specifies the distance, in pixels, between successive stripes. Defaults to 20.

-slant

Specifies the angle, in degrees, of each stripe. Defaults to 45.

-stripewidth

Specifies the width of each stripe in pixels. Defaults to 10.

-width

Specifies the desired short dimension of the BarberPole in screen units (i.e. any of the forms acceptable to Tk_GetPixels). For vertical BarberPoles this is the width; for horizontal ones it is the height. Defaults to 30.

WIDGET METHODS ^

$pole->start

Starts the animation.

$pole->stop

Stops the animation.

INSTALLATION ^

Either the usual:

        perl Makefile.PL
        make
        make install

or just stick it somewhere in \@INC where perl can find it. It's in pure Perl.
