Gtk2::Gdk::GC

NAME

Gtk2::Gdk::GC − wrapper for GdkGC

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' });

gc = Gtk2::Gdk::GC−>new_with_values ($drawable, $values=undef)

$drawable (Gtk2::Gdk::Drawable)

$values (scalar)

$gc−>set_background ($color)

$color (Gtk2::Gdk::Color)

$gc−>set_clip_mask ($mask)

$mask (scalar)

$gc−>set_clip_origin ($x, $y)

colormap = $gc−>get_colormap
$gc−>set_colormap ($colormap)

$colormap (Gtk2::Gdk::Colormap)

$dst_gc−>copy ($src_gc)

$src_gc (Gtk2::Gdk::GC)

$gc−>set_dashes ($dash_offset, ...)

$dash_offset (integer)

... (list) of integers, the length of the dash segments

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.

$gc−>set_exposures ($exposures)

$exposures (boolean)

$gc−>set_fill ($fill)

$fill (Gtk2::Gdk::Fill)

$gc−>set_font ($font)

$font (Gtk2::Gdk::Font)

$gc−>set_foreground ($color)

$color (Gtk2::Gdk::Color)

$gc−>set_function ($function)

$function (Gtk2::Gdk::Function)

$gc−>set_line_attributes ($line_width, $line_style, $cap_style, $join_style)

$line_width (integer)

$line_style (Gtk2::Gdk::LineStyle)

$cap_style (Gtk2::Gdk::CapStyle)

$join_style (Gtk2::Gdk::JoinStyle)

$gc−>offset ($x_offset, $y_offset)

$x_offset (integer)

$y_offset (integer)

$gc−>set_rgb_background ($rgb)

$rgb (unsigned)

$gc−>set_rgb_bg_color ($color)

$color (Gtk2::Gdk::Color)

$gc−>set_rgb_fg_color ($color)

$color (Gtk2::Gdk::Color)

$gc−>set_rgb_foreground ($rgb)

$rgb (unsigned)

$gc−>rgb_gc_set_background ($rgb)

$rgb (unsigned)

$gc−>rgb_gc_set_foreground ($rgb)

$rgb (unsigned)

screen = $gc−>get_screen
Since: gtk+ 2.2

$gc−>set_stipple ($stipple)

$stipple (Gtk2::Gdk::Pixmap)

$gc−>set_subwindow ($mode)

$mode (Gtk2::Gdk::SubwindowMode)

$gc−>set_tile ($tile)

$tile (Gtk2::Gdk::Pixmap)

$gc−>set_ts_origin ($x, $y)

$x (integer)

$y (integer)

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.
