Gtk2::Gdk::Window(3)

NAME
Gtk2::Gdk::Window

DESCRIPTION
"Gtk2::Gdk::Window" is a low-level window-system window. One of these is created when a widget is "realized".

As of Gtk 2.22 a window can only be created by "Gtk2::Gdk::Window->new()", "foreign_new()", etc. "Glib::Object::new()" doesn't work (segfaults on using the resulting window object). It's not possible to subclass "Gtk2::Gdk::Window" with Glib::Object::Subclass and the "Glib::Type" system, since only "gdk_window_new()" does the actual window creation, and that function always makes a "GdkWindow". (The Perl-Gtk "Gtk2::Gdk::Window->new()" wrapper ignores the class name argument.)

It may work to create a Perl level subclass and re-bless a "Gtk2::Gdk::Window->new()" into that. But like any such re-blessing it's not preserved when the object is returned from a Gtk function etc (that just gives the base Gtk class).

METHODS

  window = Gtk2::Gdk::Window->new ($parent, $attributes_ref)

•   $parent (Gtk2::Gdk::Window or undef)

•   $attributes_ref (scalar)

Create and return a new window. parent can be undef to mean the root window of the default screen. attributes_ref is a hashref containing some of the following keys,

    title              string
    event_mask         Gtk2::Gdk::EventMask flags
    x                  integer
    y                  integer
    width              integer
    height             integer
    wclass             Gtk2::Gdk::WindowClass enum
    visual             Gtk2::Gdk::Visual
    colormap           Gtk2::Gdk::Colormap
    window_type        Gtk2::Gdk::WindowType enum
    cursor             Gtk2::Gdk::Cursor
    wmclass_name       string
    wmclass_class      string
    override_redirect  boolean (integer 0 or 1)

window_type is mandatory because it defaults to "root" but of course it's not possible to create a new root window. The other fields get default values zero, empty, unset, etc.

    my $win = Gtk2::Gdk::Window->new
                (undef, { window_type => 'toplevel,
                          wclass => 'GDK_INPUT_OUTPUT',
                          x => 0,
                          y => 0,
                          width => 200,
                          height => 100 });

Incidentally, the nicknames for wclass Gtk2::Gdk::WindowClass really are "output" for input-output and "only" for input-only. Those names are a bit odd, but that's what Gtk has. You can, as for any enum, give the full names like "GDK_INPUT_OUTPUT" if desired, for some clarity.

Since: gtk+ 2.18

  (x, y, width, height, depth) = $window->get_geometry

  $window->set_geometry_hints ($geometry)

•   $geom_mask (Gtk2::Gdk::WindowHints) optional, usually inferred from $geometry

•   $geometry (scalar) Gtk2::Gdk::Geometry or hashref

$geometry is either a "Gtk2::Gdk::Geometry" object, or a hashref with the following keys and values,

    min_width     integer \ 'min-size' mask
    min_height    integer /
    max_width     integer \ 'max-size' mask
    max_height    integer /
    base_width    integer \ 'base-size' mask
    base_height   integer /
    width_inc     integer \ 'resize-inc' mask
    height_inc    integer /
    min_aspect    float   \ 'aspect' mask
    max_aspect    float   /
    win_gravity   Gtk2::Gdk::Gravity enum, 'win-gravity' mask

Optional $geom_mask is which fields of $geometry are used. If $geometry is a hashref then $geom_mask defaults to the keys supplied in the hash, so for example

    $win->set_geometry_hints ({ min_width => 20, min_height => 10});

If $geometry is a "Gtk2::Gdk::Geometry" object then you must give $geom_mask explicitly.

The 'pos', 'user-pos' and 'user-size' flags in $geom_mask have no data fields, so cannot be inferred from a $geometry hashref. If you want those flags you must pass $geom_mask explicitly.
