# This file is a Tcl script to test out the procedures in tkUnixFont.c. # It is organized in the standard fashion for Tcl tests. # # Many of these tests are visually oriented and cannot be checked # programmatically (such as "does an underlined font appear to be # underlined?"); these tests attempt to exercise the code in question, # but there are no results that can be checked. Some tests depend on the # fonts having or not having certain properties, which may not be valid # at all sites. # # Copyright (c) 1996 Sun Microsystems, Inc. # Copyright (c) 1998-1999 by Scriptics Corporation. # All rights reserved. # # RCS: @(#) $Id: unixFont.test,v 1.10.4.1 2009/04/10 15:53:00 das Exp $ package require tcltest 2.1 eval tcltest::configure $argv tcltest::loadTestedCommands if {[tk windowingsystem] eq "x11"} { set xlsf [auto_execok xlsfonts] } foreach {constraint font} { hasArial arial hasCourierNew "courier new" hasTimesNew "times new roman" } { if {[tk windowingsystem] eq "x11"} { testConstraint $constraint 1 if {[llength $xlsf]} { if {![catch {eval exec $xlsf [list *-$font-*]} res] && ![string match *unmatched* $res]} { # Newer Unix systems have more default fonts installed, # so we can't rely on fallbacks for fonts to need to # fall back on anything. testConstraint $constraint 0 } } } else { testConstraint $constraint 0 } } catch {destroy .b} toplevel .b wm geom .b +0+0 update idletasks # Font should be fixed width and have chars missing below char 32, so can # test control char expansion and missing character code. set courier {Courier -10} set cx [font measure $courier 0] label .b.l -padx 0 -pady 0 -bd 0 -highlightthickness 0 -justify left -text "0" -font fixed pack .b.l canvas .b.c -closeenough 0 set t [.b.c create text 0 0 -anchor nw -just left -font $courier] pack .b.c update set ax [winfo reqwidth .b.l] set ay [winfo reqheight .b.l] proc getsize {} { update return "[winfo reqwidth .b.l] [winfo reqheight .b.l]" } test unixfont-1.1 {TkpGetNativeFont procedure: not native} {unix noExceed} { list [catch {font measure {} xyz} msg] $msg } {1 {font "" doesn't exist}} test unixfont-1.2 {TkpGetNativeFont procedure: native} unix { font measure fixed 0 } {6} test unixfont-2.1 {TkpGetFontFromAttributes procedure: no family} unix { font actual {-size 10} set x {} } {} test unixfont-2.2 {TkpGetFontFromAttributes procedure: Times relatives} \ {unix noExceed hasTimesNew} { set x {} lappend x [lindex [font actual {-family "Times New Roman"}] 1] lappend x [lindex [font actual {-family "New York"}] 1] lappend x [lindex [font actual {-family "Times"}] 1] } {times times times} test unixfont-2.3 {TkpGetFontFromAttributes procedure: Courier relatives} \ {unix noExceed hasCourierNew} { set x {} lappend x [lindex [font actual {-family "Courier New"}] 1] lappend x [lindex [font actual {-family "Monaco"}] 1] lappend x [lindex [font actual {-family "Courier"}] 1] } {courier courier courier} test unixfont-2.4 {TkpGetFontFromAttributes procedure: Helvetica relatives} \ {unix noExceed hasArial} { set x {} lappend x [lindex [font actual {-family "Arial"}] 1] lappend x [lindex [font actual {-family "Geneva"}] 1] lappend x [lindex [font actual {-family "Helvetica"}] 1] } {helvetica helvetica helvetica} test unixfont-2.5 {TkpGetFontFromAttributes procedure: fallback} unix { font actual {-xyz-xyz-*-*-*-*-*-*-*-*-*-*-*-*} set x {} } {} test unixfont-2.6 {TkpGetFontFromAttributes: fallback to fixed family} unix { lindex [font actual {-family fixed -size 10}] 1 } {fixed} test unixfont-2.7 {TkpGetFontFromAttributes: fixed family not available!} unix { # no test available } {} test unixfont-2.8 {TkpGetFontFromAttributes: loop over returned font names} unix { lindex [font actual {-family fixed -size 31}] 1 } {fixed} test unixfont-2.9 {TkpGetFontFromAttributes: reject adobe courier if possible} {unix noExceed} { lindex [font actual {-family courier}] 1 } {courier} test unixfont-2.10 {TkpGetFontFromAttributes: scalable font found} unix { lindex [font actual {-family courier -size 37}] 3 } {37} test unixfont-2.11 {TkpGetFontFromAttributes: font cannot be loaded} unix { # On Linux, XListFonts() was returning names for fonts that do not # actually exist, causing the subsequent XLoadQueryFont() to fail # unexpectedly.
