NAME
X11::CursorFont - cursor font glyph names and numbers
SYNOPSIS
use X11::CursorFont '%CURSOR_GLYPH'; my $num = $CURSOR_GLYPH{'fleur'}; # is 52 my $name = $X11::CursorFont::CURSOR_NAME[52]; # is "fleur"
DESCRIPTION
This is the names and numbers of the glyphs in the X11 cursor font which contains various standard mouse pointer cursors. %CURSOR_GLYPH maps a glyph name to its character number in the font, $CURSOR_GLYPH{'fleur'} # is 52 @CURSOR_NAME conversely is indexed by character number and gives the glyph name, $CURSOR_NAME[52] # is "fleur" Each glyph has an associated mask at character number glyph+1 which is the shape of the cursor (the displayed vs transparent pixels). So the character numbers are always even and in @CURSOR_NAME only the even character positions have names. The cursor images can be viewed with the usual "xfd" font display program, xfd -fn cursor The names are per the Xlib /usr/include/X11/cursorfont.h file, without the "XC_" prefixes. The full list is Name Number X_cursor 0 default fat X arrow 2 based_arrow_down 4 based_arrow_up 6 boat 8 bogosity 10 bottom_left_corner 12 bottom_right_corner 14 bottom_side 16 bottom_tee 18 box_spiral 20 a square spiral center_ptr 22 circle 24 clock 26 coffee_mug 28 cross 30 cross_reverse 32 crosshair 34 "+" shape diamond_cross 36 dot 38 dotbox 40 double_arrow 42 draft_large 44 draft_small 46 draped_box 48 exchange 50 fleur 52 gobbler 54 gumby 56 hand1 58 hand2 60 heart 62 icon 64 iron_cross 66 left_ptr 68 left_side 70 left_tee 72 leftbutton 74 ll_angle 76 lr_angle 78 man 80 middlebutton 82 mouse 84 pencil 86 pirate 88 skull and crossbones plus 90 question_arrow 92 right_ptr 94 right_side 96 right_tee 98 rightbutton 100 rtl_logo 102 sailboat 104 sb_down_arrow 106 sb_h_double_arrow 108 sb_left_arrow 110 sb_right_arrow 112 sb_up_arrow 114 sb_v_double_arrow 116 shuttle 118 sizing 120 spider 122 spraycan 124 star 126 target 128 tcross 130 top_left_arrow 132 top_left_corner 134 top_right_corner 136 top_side 138 top_tee 140 trek 142 ul_angle 144 umbrella 146 ur_angle 148 watch 150 a good "busy" indicator xterm 152 a vertical insertion bar "X_cursor" is the usual default when the server first starts or when the root window is set to cursor "None".
VARIABLES
%X11::CursorFont::CURSOR_GLYPH A mapping of glyph name to cursor font character number. @X11::CursorFont::CURSOR_NAME A table of cursor font character number to glyph name.
EXPORTS
Nothing is exported by default, but %CURSOR_GLYPH and @CURSOR_NAME can be selected in usual "Exporter" style (see Exporter), use X11::CursorFont '%CURSOR_GLYPH', '@CURSOR_NAME';
EXAMPLE
For reference, here's how to create a cursor from a desired glyph, my $cursor_name = 'spraycan'; my $cursor_glyph = $CURSOR_GLYPH{$cursor_name}; # number my $cursor_font = $X->new_rsrc; $X->OpenFont ($cursor_font, "cursor"); # cursor font my $cursor = $X->new_rsrc; $X->CreateGlyphCursor ($cursor, $cursor_font, # font $cursor_font, # mask font $cursor_glyph, # glyph $cursor_glyph + 1, # and its mask 0,0,0, # foreground, black 0xFFFF,0xFFFF,0xFFFF); # background, white $X->CloseFont ($cursor_font); # then use $cursor with CreateWindow or ChangeWindowAttributes # cursor => $cursor The $cursor_font could be kept open if used repeatedly. Opening and closing isn't a round-trip, so an open when needed may be enough. Any RGB colours can be given in "CreateGlyphCursor()", but actual appearance on screen will be limited by the hardware. All cursors in the core protocol are two-colours with pixels fully opaque or fully transparent as per this create. The RENDER extension, when available, can do multi-colour and partial transparency if desired (see X11::Protocol::Ext::RENDER).
