1 # 2 # Font specifications. 3 # 4 # This file, [source]d at initialization time, sets up the following 5 # symbolic fonts based on the current platform: 6 # 7 # TkDefaultFont -- default for GUI items not otherwise specified 8 # TkTextFont -- font for user text (entry, listbox, others) 9 # TkFixedFont -- standard fixed width font 10 # TkHeadingFont -- headings (column headings, etc) 11 # TkCaptionFont -- dialog captions (primary text in alert dialogs, etc.) 12 # TkTooltipFont -- font to use for tooltip windows 13 # TkIconFont -- font to use for icon captions 14 # TkMenuFont -- used to use for menu items 15 # 16 # In Tk 8.5, some of these fonts may be provided by the TIP#145 implementation 17 # (On Windows and Mac OS X as of Oct 2007). 18 # 19 # +++ Platform notes: 20 # 21 # Windows: 22 # The default system font changed from "MS Sans Serif" to "Tahoma" 23 # in Windows XP/Windows 2000. 24 # 25 # MS documentation says to use "Tahoma 8" in Windows 2000/XP, 26 # although many MS programs still use "MS Sans Serif 8" 27 # 28 # Should use SystemParametersInfo() instead. 29 # 30 # Mac OSX / Aqua: 31 # Quoth the Apple HIG: 32 # The _system font_ (Lucida Grande Regular 13 pt) is used for text 33 # in menus, dialogs, and full-size controls. 34 # [...] Use the _view font_ (Lucida Grande Regular 12pt) as the default 35 # font of text in lists and tables. 36 # [...] Use the _emphasized system font_ (Lucida Grande Bold 13 pt) 37 # sparingly. It is used for the message text in alerts. 38 # [...] The _small system font_ (Lucida Grande Regular 11 pt) [...] 39 # is also the default font for column headings in lists, for help tags, 40 # and for small controls. 41 # 42 # Note that the font for column headings (TkHeadingFont) is 43 # _smaller_ than the default font. 44 # 45 # There does not appear to be any recommendations for fixed-width fonts. 46 # 47 # X11: 48 # Need a way to tell if Xft is enabled or not. 49 # For now, assume patch #971980 applied. 50 # 51 # "Classic" look used Helvetica bold for everything except 52 # for entry widgets, which use Helvetica medium. 53 # Most other toolkits use medium weight for all UI elements, 54 # which is what we do now. 55 # 56 # Font size specified in pixels on X11, not points. 57 # This is Theoretically Wrong, but in practice works better; using 58 # points leads to huge inconsistencies across different servers. 59 # 60 61 namespace eval ttk { 62 63 variable tip145 [catch {font create TkDefaultFont}] 64 catch {font create TkTextFont} 65 catch {font create TkHeadingFont} 66 catch {font create TkCaptionFont} 67 catch {font create TkTooltipFont} 68 catch {font create TkFixedFont} 69 catch {font create TkIconFont} 70 catch {font create TkMenuFont} 71 catch {font create TkSmallCaptionFont} 72 73 if {!$tip145} { 74 variable F ;# miscellaneous platform-specific font parameters 75 switch -- [tk windowingsystem] { 76 win32 { 77 # In safe interps there is no osVersion element. 78 if {[info exists tcl_platform(osVersion)]} { 79 if {$tcl_platform(osVersion) >= 5.0} { 80 set F(family) "Tahoma" 81 } else { 82 set F(family) "MS Sans Serif" 83 } 84 } else { 85 if {[lsearch -exact [font families] Tahoma] != -1} { 86 set F(family) "Tahoma" 87 } else { 88 set F(family) "MS Sans Serif" 89 } 90 } 91 set F(size) 8 92 93 font configure TkDefaultFont -family $F(family) -size $F(size) 94 font configure TkTextFont -family $F(family) -size $F(size) 95 font configure TkHeadingFont -family $F(family) -size $F(size) 96 font configure TkCaptionFont -family $F(family) -size $F(size) \ 97 -weight bold 98 font configure TkTooltipFont -family $F(family) -size $F(size) 99 font configure TkFixedFont -family Courier -size 10 100 font configure TkIconFont -family $F(family) -size $F(size) 101 font configure TkMenuFont -family $F(family) -size $F(size) 102 font configure TkSmallCaptionFont -family $F(family) -size $F(size) 103 } 104 aqua { 105 set F(family) "Lucida Grande" 106 set F(fixed) "Monaco" 107 set F(menusize) 14 108 set F(size) 13 109 set F(viewsize) 12 110 set F(smallsize) 11 111 set F(labelsize) 10 112 set F(fixedsize) 11 113 114 font configure TkDefaultFont -family $F(family) -size $F(size) 115 font configure TkTextFont -family $F(family) -size $F(size) 116 font configure TkHeadingFont -family $F(family) -size $F(smallsize) 117 font configure TkCaptionFont -family $F(family) -size $F(size) \ 118 -weight bold 119 font configure TkTooltipFont -family $F(family) -size $F(smallsize) 120 font configure TkFixedFont -family $F(fixed) -size $F(fixedsize) 121 font configure TkIconFont -family $F(family) -size $F(size) 122 font configure TkMenuFont -family $F(family) -size $F(menusize) 123 font configure TkSmallCaptionFont -family $F(family) -size $F(labelsize) 124 } 125 default - 126 x11 { 127 if {![catch {tk::pkgconfig get fontsystem} F(fs)] && $F(fs) eq "xft"} { 128 set F(family) "sans-serif" 129 set F(fixed) "monospace" 130 } else { 131 set F(family) "Helvetica" 132 set F(fixed) "courier" 133 } 134 set F(size) -12 135 set F(ttsize) -10 136 set F(capsize) -14 137 set F(fixedsize) -12 138 139 font configure TkDefaultFont -family $F(family) -size $F(size) 140 font configure TkTextFont -family $F(family) -size $F(size) 141 font configure TkHeadingFont -family $F(family) -size $F(size) \ 142 -weight bold 143 font configure TkCaptionFont -family $F(family) -size $F(capsize) \ 144 -weight bold 145 font configure TkTooltipFont -family $F(family) -size $F(ttsize) 146 font configure TkFixedFont -family $F(fixed) -size $F(fixedsize) 147 font configure TkIconFont -family $F(family) -size $F(size) 148 font configure TkMenuFont -family $F(family) -size $F(size) 149 font configure TkSmallCaptionFont -family $F(family) -size $F(ttsize) 150 } 151 } 152 unset -nocomplain F 153 } 154 155 } 156 157 #*EOF*
