NAME<\/a> ______________________________________________________________________________<\/p>\n font \u2212 Create and inspect fonts.<\/p>\n font<\/b> option<\/i> ?arg arg …<\/i>? ______________________________________________________________________________<\/p>\n The font<\/b> command provides several facilities for dealing with fonts, such as defining named fonts and inspecting the actual attributes of a font. The command has several different forms, determined by the first argument. The following forms are currently supported: Returns information about the actual attributes that are obtained when font<\/i> is used on window<\/i>\u2019s display; the actual attributes obtained may differ from the attributes requested due to platform-dependent limitations, such as the availability of font families and point sizes. font<\/i> is a font description; see FONT DESCRIPTIONS<\/b> below. If the window<\/i> argument is omitted, it defaults to the main window. If option<\/i> is specified, returns the value of that attribute; if it is omitted, the return value is a list of all the attributes and their values. See FONT OPTIONS<\/b> below for a list of the possible attributes. If the char<\/i> argument is supplied, it must be a single character. The font attributes returned will be those of the specific font used to render that character, which will be different from the base font if the base font does not contain the given character. If char<\/i> may be a hyphen, it should be preceded by \u2212\u2212<\/b> to distinguish it from a misspelled option<\/i>.<\/p>\n font configure<\/b> fontname<\/i> ?option<\/i>? ?value option value …<\/i>?<\/p>\n Query or modify the desired attributes for the named font called fontname<\/i>. If no option<\/i> is specified, returns a list describing all the options and their values for fontname<\/i>. If a single option<\/i> is specified with no value<\/i>, then returns the current value of that attribute. If one or more option<\/i>\u2212value<\/i> pairs are specified, then the command modifies the given named font to have the given values; in this case, all widgets using that font will redisplay themselves using the new attributes for the font. See FONT OPTIONS<\/b> below for a list of the possible attributes.<\/p>\n Note that on Aqua\/Mac OS X, the system fonts (see PLATFORM SPECIFIC FONTS<\/b> below) may not be actually altered because they are implemented by the system theme. To achieve the effect of modification, use font actual<\/b> to get their configuration and font create<\/b> to synthesize a copy of the font which can be modified.<\/p>\n font create<\/b> ?fontname<\/i>? ?option value …<\/i>?<\/p>\n Creates a new named font and returns its name. fontname<\/i> specifies the name for the font; if it is omitted, then Tk generates a new name of the form font<\/b>x<\/i>, where x<\/i> is an integer. There may be any number of option<\/i>\u2212value<\/i> pairs, which provide the desired attributes for the new named font. See FONT OPTIONS<\/b> below for a list of the possible attributes.<\/p>\n font delete<\/b> fontname<\/i> ?fontname …<\/i>?<\/p>\n Delete the specified named fonts. If there are widgets using the named font, the named font will not actually be deleted until all the instances are released. Those widgets will continue to display using the last known values for the named font. If a deleted named font is subsequently recreated with another call to font create<\/b>, the widgets will use the new named font and redisplay themselves using the new attributes of that font.<\/p>\n font families<\/b> ?\u2212displayof<\/b> window<\/i>?<\/p>\n The return value is a list of the case-insensitive names of all font families that exist on window<\/i>\u2019s display. If the window<\/i> argument is omitted, it defaults to the main window.<\/p>\n font measure<\/b> font<\/i> ?\u2212displayof<\/b> window<\/i>? text<\/i><\/p>\n Measures the amount of space the string text<\/i> would use in the given font<\/i> when displayed in window<\/i>. font<\/i> is a font description; see FONT DESCRIPTIONS<\/b> below. If the window<\/i> argument is omitted, it defaults to the main window. The return value is the total width in pixels of text<\/i>, not including the extra pixels used by highly exaggerated characters such as cursive \u201cf\u201d. If the string contains newlines or tabs, those characters are not expanded or treated specially when measuring the string.<\/p>\n font metrics<\/b> font<\/i> ?\u2212displayof<\/b> window<\/i>? ?option<\/i>?<\/p>\n Returns information about the metrics (the font-specific data), for font<\/i> when it is used on window<\/i>\u2019s display. font<\/i> is a font description; see FONT DESCRIPTIONS<\/b> below. If the window<\/i> argument is omitted, it defaults to the main window. If option<\/i> is specified, returns the value of that metric; if it is omitted, the return value is a list of all the metrics and their values. See FONT METRICS<\/b> below for a list of the possible metrics.<\/p>\n font names<\/b><\/p>\n The return value is a list of all the named fonts that are currently defined.<\/p>\n The following formats are accepted as a font description anywhere font<\/i> is specified as an argument above; these same forms are also permitted when specifying the \u2212font<\/b> option for widgets. The name of a named font, created using the font create<\/b> command. When a widget uses a named font, it is guaranteed that this will never cause an error, as long as the named font exists, no matter what potentially invalid or meaningless set of attributes the named font has. If the named font cannot be displayed with exactly the specified attributes, some other close font will be substituted automatically.<\/p>\n [2] systemfont<\/i><\/p>\n The platform-specific name of a font, interpreted by the graphics server. This also includes, under X, an XLFD (see [4]) for which a single \u201c*<\/b>\u201d character was used to elide more than one field in the middle of the name. See PLATFORM SPECIFIC FONTS<\/b> for a list of the system fonts.<\/p>\n [3] family<\/i> ?size<\/i>? ?style<\/i>? ?style …<\/i>?<\/p>\n A properly formed list whose first element is the desired font family<\/i> and whose optional second element is the desired size<\/i>. The interpretation of the size<\/i> attribute follows the same rules described for \u2212size<\/b> in FONT OPTIONS<\/b> below. Any additional optional arguments following the size<\/i> are font style<\/i>s. Possible values for the style<\/i> arguments are as follows:<\/p>\n
