NAME

Gtk2::Ex::Dashes -- widget displaying row of dashes

SYNOPSIS

 use Gtk2::Ex::Dashes;
 my $dashes = Gtk2::Ex::Dashes->new;

WIDGET HIERARCHY

Gtk2::Ex::Dashes is a subclass of Gtk2::Misc.

    Gtk2::Widget
      Gtk2::Misc
        Gtk2::Ex::Dashes

DESCRIPTION

A Gtk2::Ex::Dashes widget displays a line of dashes, either horizontally or vertically.

    +--------------------------------+
    |                                |
    |  ====  ====  ====  ====  ====  |
    |                                |
    +--------------------------------+

It's similar to Gtk2::Separator, but a dashed line, and the Gtk2::Ex::Dashes::MenuItem subclass looks like Gtk2::TearoffMenuItem but is a plain item, not driving the menu.

Line segments are drawn per the widget style (see Gtk2::Style) and positioned in the widget area per the Gtk2::Misc properties described below. There's nothing to control the length and spacing of the line segments, currently they just scale with the line thickness to keep the display sensible.

See examples/simple.pl or examples/vertical.pl in the sources for the simplest usage, or examples/settings.pl to interactively see the effect of settings.

FUNCTIONS

$dashes = Gtk2::Ex::Dashes->new (key=>value,...)

Create and return a new Dashes widget. Optional key/value pairs can be given to set initial properties, as per Glib::Object->new.

    my $dashes = Gtk2::Ex::Dashes->new
                   (xalign => 0, direction => 'vertical');

PROPERTIES

orientation (Gtk2::Orientation enum, default "horizontal")

Whether to draw a horizontal line or a vertical line.

xalign (float, default 0.5)
yalign (float, default 0.5)

These Gtk2::Misc properties control positioning of the line within its allocated area. The default 0.5 means centre it.

xalign for a horizontal line can be thought of as positioning one dash segment somewhere between the left and right ends, and then the further segments drawn each way from there to fill the window. Similarly yalign when vertical.

If the widget text direction (see set_direction in Gtk2::Widget) is rtl then the sense of xalign is reversed, so 0 means the right edge instead of the left.
