NAME

Gtk2::Gdk::GC

HIERARCHY

   Glib::Object
   +----Gtk2::Gdk::GC
 
 

METHODS

gc = Gtk2::Gdk::GC->new ($drawable, $values=undef)

*

$drawable (Gtk2::Gdk::Drawable)

*

$values (scalar)

Create and return a new GC.
$drawable is used for the depth and the display ("Gtk2::Gdk::Display") for the GC. The GC can then be used with any drawable of the same depth on that display.
$values is a hashref containing some of the following keys,

     foreground          Gtk2::Gdk::Color
     background          Gtk2::Gdk::Color
     font                Gtk2::Gdk::Font
     function            Gtk2::Gdk::Function enum
     fill                Gtk2::Gdk::Fill enum
     tile                Gtk2::Gdk::Pixmap
     stipple             Gtk2::Gdk::Pixmap
     clip_mask           Gtk2::Gdk::Pixmap
     subwindow_mode      Gtk2::Gdk::SubwindowMode enum
     ts_x_origin         integer
     ts_y_origin         integer
     clip_x_origin       integer
     clip_y_origin       integer
     graphics_exposures  boolean integer 1 or 0
     line_width          integer
     line_style          Gtk2::Gdk::LineStyle enum
     cap_style           Gtk2::Gdk::CapStyle enum
     join_style          Gtk2::Gdk::JoinStyle enum
 
 

Keys not given get default values. For the "foreground" and "background" colour objects only the "pixel" field is used; the red, green and blue are ignored. For example

     my $pixel = 0x123456;
     my $color = Gtk2::Gdk::Color->new (0,0,0, $pixel);
     my $gc = Gtk2::Gdk::GC->new_with_values
       ($win, { foreground => $color,
                line_style => 'on_off_dash' });

Sets the way dashed-lines are drawn. Lines will be drawn with alternating on and off segments of the lengths specified in list of dashes. The manner in which the on and off segments are drawn is determined by the line_style value of the GC.

scalar = $gc->get_values

Return the attributes of $gc in the form of a hashref with keys and values as described with "new" above.
In the "foreground" and "background" colour objects returned only the "pixel" fields are set; the red, green and blue fields are garbage.

$gc->set_values ($values)

*

$values (scalar)

Set some of the attributes of $gc. $values is a hashref of keys and values as described for "new" and "new_with_values" above. Fields not present in $values are left unchanged.
