In addition to this, * certain files will be read at the end of gtk_init(). * Unless modified, the files looked for will be * `SYSCONFDIR/gtk-2.0/gtkrc` * and `.gtkrc-3.0` in the users home directory. * (`SYSCONFDIR` defaults to * `/usr/local/etc`. It can be changed with the * `--prefix` or `--sysconfdir` options when * configuring GTK+.) * * The set of these “default” files * can be retrieved with gtk_rc_get_default_files() * and modified with gtk_rc_add_default_file() and * gtk_rc_set_default_files(). * Additionally, the `GTK2_RC_FILES` environment variable * can be set to a #G_SEARCHPATH_SEPARATOR_S-separated list of files * in order to overwrite the set of default files at runtime. * * # Locale Specific Files # {#locale-specific-rc} * * For each RC file, in addition to the file itself, GTK+ will look for * a locale-specific file that will be parsed after the main file. * For instance, if `LANG` is set to `ja_JP.ujis`, * when loading the default file `~/.gtkrc` then GTK+ looks * for `~/.gtkrc.ja_JP` and `~/.gtkrc.ja`, * and parses the first of those that exists. * * # Pathnames and Patterns # * * A resource file defines a number of styles and key bindings and * attaches them to particular widgets. The attachment is done * by the `widget`, `widget_class`, * and `class` declarations. As an example * of such a statement: * * |[ * widget "mywindow.*.GtkEntry" style "my-entry-class" * ]| * * attaches the style `"my-entry-class"` to all * widgets whose “widget path” matches the * “pattern” `"mywindow.*.GtkEntry"`. * That is, all #GtkEntry widgets which are part of a #GtkWindow named * `"mywindow"`. * * The patterns here are given in the standard shell glob syntax. * The `"?"` wildcard matches any character, while * `"*"` matches zero or more of any character. * The three types of matching are against the widget path, the * “class path” and the class hierarchy. Both the * widget path and the class path consist of a `"."` * separated list of all the parents of the widget and the widget itself * from outermost to innermost. The difference is that in the widget path, * the name assigned by gtk_widget_set_name() is used if present, otherwise * the class name of the widget, while for the class path, the class name is * always used. * * Since GTK+ 2.10, `widget_class` paths can also contain * substrings, which are matching the class with the given name and any * derived classes. For instance, * |[ * widget_class "*.GtkLabel" style "my-style" * ]| * will match #GtkLabel widgets which are contained in any kind of menu item. * * So, if you have a #GtkEntry named `"myentry"`, inside of a horizontal * box in a window named `"mywindow"`, then the widget path is: * `"mywindow.GtkHBox.myentry"` while the class path is: * `"GtkWindow.GtkHBox.GtkEntry"`. * * Matching against class is a little different. The pattern match is done * against all class names in the widgets class hierarchy (not the layout * hierarchy) in sequence, so the pattern: * |[ * class "GtkButton" style "my-style" * ]| * will match not just #GtkButton widgets, but also #GtkToggleButton and * #GtkCheckButton widgets, since those classes derive from #GtkButton. * * Additionally, a priority can be specified for each pattern, and styles * override other styles first by priority, then by pattern type and then * by order of specification (later overrides earlier). The priorities * that can be specified are (highest to lowest): * * - `highest` * * - `rc` * * - `theme` * * - `application` * * - `gtk` * * - `lowest` * * `rc` is the default for styles * read from an RC file, `theme` * is the default for styles read from theme RC files, * `application` * should be used for styles an application sets * up, and `gtk` is used for styles * that GTK+ creates internally. * * # Theme gtkrc Files # * * Theme RC files are loaded first from under the `~/.themes/`, * then from the directory from gtk_rc_get_theme_dir(). The files looked at will * be `gtk-3.0/gtkrc`. * * When the application prefers dark themes * (see the #GtkSettings:gtk-application-prefer-dark-theme property for details), * `gtk-3.0/gtkrc-dark` will be loaded first, and if not present * `gtk-3.0/gtkrc` will be loaded. * * # Optimizing RC Style Matches # * * Everytime a widget is created and added to the layout hierarchy of a #GtkWindow * ("anchored" to be exact), a list of matching RC styles out of all RC styles read * in so far is composed. * For this, every RC style is matched against the widgets class path, * the widgets name path and widgets inheritance hierarchy. * As a consequence, significant slowdown can be caused by utilization of many * RC styles and by using RC style patterns that are slow or complicated to match * against a given widget. * The following ordered list provides a number of advices (prioritized by * effectiveness) to reduce the performance overhead associated with RC style * matches: * * 1. Move RC styles for specific applications into RC files dedicated to those * applications and parse application specific RC files only from * applications that are affected by them. * This reduces the overall amount of RC styles that have to be considered * for a match across a group of applications. * * 2. Merge multiple styles which use the same matching rule, for instance: * |[ * style "Foo" { foo_content } * class "X" style "Foo" * style "Bar" { bar_content } * class "X" style "Bar" * ]| * is faster to match as: * |[ * style "FooBar" { foo_content bar_content } * class "X" style "FooBar" * ]| * * 3. Use of wildcards should be avoided, this can reduce the individual RC style * match to a single integer comparison in most cases. * * 4. To avoid complex recursive matching, specification of full class names * (for `class` matches) or full path names (for * `widget` and `widget_class` matches) * is to be preferred over shortened names * containing `"*"` or `"?"`. * * 5. If at all necessary, wildcards should only be used at the tail or head * of a pattern. This reduces the match complexity to a string comparison * per RC style. * * 6. When using wildcards, use of `"?"` should be preferred * over `"*"`. This can reduce the matching complexity from * O(n^2) to O(n). For example `"Gtk*Box"` can be turned into * `"Gtk?Box"` and will still match #GtkHBox and #GtkVBox. * * 7. The use of `"*"` wildcards should be restricted as much * as possible, because matching `"A*B*C*RestString"` can * result in matching complexities of O(n^2) worst case. * * # Toplevel Declarations # * * An RC file is a text file which is composed of a sequence * of declarations. `“#”` characters delimit comments and * the portion of a line after a `“#”` is ignored when parsing * an RC file. * * The possible toplevel declarations are: * * * `binding name * { ... }` * * Declares a binding set. * * * `class pattern * [ style | binding ][ : priority ] * name` * * Specifies a style or binding set for a particular * branch of the inheritance hierarchy. * * * `include filename` * * Parses another file at this point. If * filename is not an absolute filename, * it is searched in the directories of the currently open RC files. * * GTK+ also tries to load a * [locale-specific variant][locale-specific-rc] of * the included file. * * * `module_path path` * * Sets a path (a list of directories separated * by colons) that will be searched for theme engines referenced in * RC files. * * * `pixmap_path path` * * Sets a path (a list of directories separated * by colons) that will be searched for pixmaps referenced in * RC files. * * * `im_module_file pathname` * * Sets the pathname for the IM modules file. Setting this from RC files * is deprecated; you should use the environment variable `GTK_IM_MODULE_FILE` * instead. * * * `style name [ = * parent ] { ... }` * * Declares a style. * * * `widget pattern * [ style | binding ][ : priority ] * name` * * Specifies a style or binding set for a particular * group of widgets by matching on the widget pathname. * * * `widget_class pattern * [ style | binding ][ : priority ] * name` * * Specifies a style or binding set for a particular * group of widgets by matching on the class pathname. * * * setting = value * * Specifies a value for a [setting][GtkSettings]. * Note that settings in RC files are overwritten by system-wide settings * (which are managed by an XSettings manager on X11). * * # Styles # * * A RC style is specified by a `style` * declaration in a RC file, and then bound to widgets * with a `widget`, `widget_class`, * or `class` declaration. All styles * applying to a particular widget are composited together * with `widget` declarations overriding * `widget_class` declarations which, in * turn, override `class` declarations. * Within each type of declaration, later declarations override * earlier ones. * * Within a `style` declaration, the possible * elements are: * * * `bg[state] = color` * * Sets the color used for the background of most widgets. * * * `fg[state] = color` * * Sets the color used for the foreground of most widgets. * * * `base[state] = color` * * Sets the color used for the background of widgets displaying * editable text. This color is used for the background * of, among others, #GtkText, #GtkEntry, #GtkList, and #GtkCList. * * * `text[state] = * color` * * Sets the color used for foreground of widgets using * `base` for the background color. * * * `xthickness = * number` * * Sets the xthickness, which is used for various horizontal padding * values in GTK+. * * * `ythickness = * number` * * Sets the ythickness, which is used for various vertical padding * values in GTK+. * * * `bg_pixmap[state] = * pixmap` * * Sets a background pixmap to be used in place of the `bg` color * (or for #GtkText, in place of the `base` color. The special * value `""` may be used to indicate that the widget should * use the same background pixmap as its parent. The special value * `""` may be used to indicate no background pixmap. * * `font = font` * * Starting with GTK+ 2.0, the “font” and “fontset” * declarations are ignored; use “font_name” declarations instead. * * * `fontset = font` * * Starting with GTK+ 2.0, the “font” and “fontset” * declarations are ignored; use “font_name” declarations instead. * * * `font_name = font` * * Sets the font for a widget. font must be * a Pango font name, e.g. “Sans Italic 10” . * For details about Pango font names, see * pango_font_description_from_string(). * * * `stock["stock-id"] = { icon source specifications }` * * Defines the icon for a stock item. * * * `color["color-name"] = color specification` * * Since 2.10, this element can be used to defines symbolic colors. See below for * the syntax of color specifications. * * * `engine "engine" { engine-specific * settings }` * * Defines the engine to be used when drawing with this style. * * * `class::property = value` * * Sets a [style property][style-properties] for a widget class. * * The colors and background pixmaps are specified as a function of the * state of the widget. The states are: * * * `NORMAL` * * A color used for a widget in its normal state. * * * `ACTIVE` * * A variant of the `NORMAL` color used when the * widget is in the %GTK_STATE_ACTIVE state, and also for * the trough of a ScrollBar, tabs of a NoteBook * other than the current tab and similar areas. * Frequently, this should be a darker variant * of the `NORMAL` color. * * * `PRELIGHT` * * A color used for widgets in the %GTK_STATE_PRELIGHT state. This * state is the used for Buttons and MenuItems * that have the mouse cursor over them, and for * their children. * * * `SELECTED` * * A color used to highlight data selected by the user. * for instance, the selected items in a list widget, and the * selection in an editable widget. * * * `INSENSITIVE` * * A color used for the background of widgets that have * been set insensitive with gtk_widget_set_sensitive(). * * ## Color Format ## {#color-format} * * Colors can be specified as a string containing a color name (GTK+ knows * all names from the X color database `/usr/lib/X11/rgb.txt`), * in one of the hexadecimal forms `#rrrrggggbbbb`, * `#rrrgggbbb`, `#rrggbb`, * or `#rgb`, where `r`, * `g` and `b` are * hex digits, or they can be specified as a triplet * `{ r, g, * b}`, where `r`, * `g` and `b` are either integers in * the range 0-65535 or floats in the range 0.0-1.0. * * Since 2.10, colors can also be specified by refering to a symbolic color, as * follows: `@color-name`, or by using expressions to combine * colors. The following expressions are currently supported: * * * mix (factor, color1, color2) * * Computes a new color by mixing color1 and * color2. The factor * determines how close the new color is to color1. * A factor of 1.0 gives pure color1, a factor of * 0.0 gives pure color2. * * * shade (factor, color) * * Computes a lighter or darker variant of color. * A factor of 1.0 leaves the color unchanged, smaller * factors yield darker colors, larger factors yield lighter colors. * * * lighter (color) * * This is an abbreviation for * `shade (1.3, color)`. * * * darker (color) * * This is an abbreviation for * `shade (0.7, color)`. * * Here are some examples of color expressions: * * |[ * mix (0.5, "red", "blue") * shade (1.5, mix (0.3, "#0abbc0", { 0.3, 0.5, 0.9 })) * lighter (@foreground) * ]| * * In a `stock` definition, icon sources are specified as a * 4-tuple of image filename or icon name, text direction, widget state, and size, in that * order. Each icon source specifies an image filename or icon name to use with a given * direction, state, and size. Filenames are specified as a string such * as `"itemltr.png"`, while icon names (looked up * in the current icon theme), are specified with a leading * `@`, such as `@"item-ltr"`. * The `*` character can be used as a * wildcard, and if direction/state/size are omitted they default to * `*`. So for example, the following specifies different icons to * use for left-to-right and right-to-left languages: * * |[ * stock["my-stock-item"] = * { * { "itemltr.png", LTR, *, * }, * { "itemrtl.png", RTL, *, * } * } * ]| * * This could be abbreviated as follows: * * |[ * stock["my-stock-item"] = * { * { "itemltr.png", LTR }, * { "itemrtl.png", RTL } * } * ]| * * You can specify custom icons for specific sizes, as follows: * * |[ * stock["my-stock-item"] = * { * { "itemmenusize.png", *, *, "gtk-menu" }, * { "itemtoolbarsize.png", *, *, "gtk-large-toolbar" } * { "itemgeneric.png" } // implicit *, *, * as a fallback * } * ]| * * The sizes that come with GTK+ itself are `"gtk-menu"`, * `"gtk-small-toolbar"`, `"gtk-large-toolbar"`, * `"gtk-button"`, `"gtk-dialog"`. Applications * can define other sizes. * * It’s also possible to use custom icons for a given state, for example: * * |[ * stock["my-stock-item"] = * { * { "itemprelight.png", *, PRELIGHT }, * { "iteminsensitive.png", *, INSENSITIVE }, * { "itemgeneric.png" } // implicit *, *, * as a fallback * } * ]| * * When selecting an icon source to use, GTK+ will consider text direction most * important, state second, and size third. It will select the best match based on * those criteria. If an attribute matches exactly (e.g. you specified * `PRELIGHT` or specified the size), GTK+ won’t modify the image; * if the attribute matches with a wildcard, GTK+ will scale or modify the image to * match the state and size the user requested. * * # Key bindings # * * Key bindings allow the user to specify actions to be * taken on particular key presses. The form of a binding * set declaration is: * * |[ * binding name { * bind key { * signalname (param, ...) * ... * } * ... * } * ]| * * `key` is a string consisting of a series of modifiers followed by * the name of a key. The modifiers can be: * * - `` * * - `` * * - `` * * - `` * * - `` * * - `` * * - `` * * - `` * * - `` * * - `` * * - `` * * - `` * * - `` * * - `` * * `` is an alias for ``, `` is an alias for * ``, and `` is an alias for ``. * * The action that is bound to the key is a sequence of signal names * (strings) followed by parameters for each signal. The signals must * be action signals. (See g_signal_new()). Each parameter can be a * float, integer, string, or unquoted string representing an enumeration * value. The types of the parameters specified must match the types of * the parameters of the signal. * * Binding sets are connected to widgets in the same manner as styles, * with one difference: Binding sets override other binding sets first * by pattern type, then by priority and then by order of specification. * The priorities that can be specified and their default values are the * same as for styles. */ enum { PATH_ELT_PSPEC, PATH_ELT_UNRESOLVED, PATH_ELT_TYPE }; typedef struct { gint type; union { GType class_type; gchar *class_name; GPatternSpec *pspec; } elt; } PathElt; typedef struct { GSList *color_hashes; } GtkRcStylePrivate; #define GTK_RC_STYLE_GET_PRIVATE(obj) ((GtkRcStylePrivate *) gtk_rc_style_get_instance_private ((GtkRcStyle *) (obj))) static void gtk_rc_style_finalize (GObject *object); static void gtk_rc_style_real_merge (GtkRcStyle *dest, GtkRcStyle *src); static GtkRcStyle* gtk_rc_style_real_create_rc_style (GtkRcStyle *rc_style); static GtkStyle* gtk_rc_style_real_create_style (GtkRcStyle *rc_style); static gint gtk_rc_properties_cmp (gconstpointer bsearch_node1, gconstpointer bsearch_node2); static void insert_rc_property (GtkRcStyle *style, GtkRcProperty *property, gboolean replace); static const GScannerConfig gtk_rc_scanner_config = { ( " \t\r\n" ) /* cset_skip_characters */, ( "_" G_CSET_a_2_z G_CSET_A_2_Z ) /* cset_identifier_first */, ( G_CSET_DIGITS "-_" G_CSET_a_2_z G_CSET_A_2_Z ) /* cset_identifier_nth */, ( "#\n" ) /* cpair_comment_single */, TRUE /* case_sensitive */, TRUE /* skip_comment_multi */, TRUE /* skip_comment_single */, TRUE /* scan_comment_multi */, TRUE /* scan_identifier */, FALSE /* scan_identifier_1char */, FALSE /* scan_identifier_NULL */, TRUE /* scan_symbols */, TRUE /* scan_binary */, TRUE /* scan_octal */, TRUE /* scan_float */, TRUE /* scan_hex */, TRUE /* scan_hex_dollar */, TRUE /* scan_string_sq */, TRUE /* scan_string_dq */, TRUE /* numbers_2_int */, FALSE /* int_2_float */, FALSE /* identifier_2_string */, TRUE /* char_2_token */, TRUE /* symbol_2_token */, FALSE /* scope_0_fallback */, }; static const gchar symbol_names[] = "include\0" "NORMAL\0" "ACTIVE\0" "PRELIGHT\0" "SELECTED\0" "INSENSITIVE\0" "fg\0" "bg\0" "text\0" "base\0" "xthickness\0" "ythickness\0" "font\0" "fontset\0" "font_name\0" "bg_pixmap\0" "pixmap_path\0" "style\0" "binding\0" "bind\0" "widget\0" "widget_class\0" "class\0" "lowest\0" "gtk\0" "application\0" "theme\0" "rc\0" "highest\0" "engine\0" "module_path\0" "stock\0" "im_module_file\0" "LTR\0" "RTL\0" "color\0" "unbind\0"; static const struct { guint name_offset; guint token; } symbols[] = { { 0, GTK_RC_TOKEN_INCLUDE }, { 8, GTK_RC_TOKEN_NORMAL }, { 15, GTK_RC_TOKEN_ACTIVE }, { 22, GTK_RC_TOKEN_PRELIGHT }, { 31, GTK_RC_TOKEN_SELECTED }, { 40, GTK_RC_TOKEN_INSENSITIVE }, { 52, GTK_RC_TOKEN_FG }, { 55, GTK_RC_TOKEN_BG }, { 58, GTK_RC_TOKEN_TEXT }, { 63, GTK_RC_TOKEN_BASE }, { 68, GTK_RC_TOKEN_XTHICKNESS }, { 79, GTK_RC_TOKEN_YTHICKNESS }, { 90, GTK_RC_TOKEN_FONT }, { 95, GTK_RC_TOKEN_FONTSET }, { 103, GTK_RC_TOKEN_FONT_NAME }, { 113, GTK_RC_TOKEN_BG_PIXMAP }, { 123, GTK_RC_TOKEN_PIXMAP_PATH }, { 135, GTK_RC_TOKEN_STYLE }, { 141, GTK_RC_TOKEN_BINDING }, { 149, GTK_RC_TOKEN_BIND }, { 154, GTK_RC_TOKEN_WIDGET }, { 161, GTK_RC_TOKEN_WIDGET_CLASS }, { 174, GTK_RC_TOKEN_CLASS }, { 180, GTK_RC_TOKEN_LOWEST }, { 187, GTK_RC_TOKEN_GTK }, { 191, GTK_RC_TOKEN_APPLICATION }, { 203, GTK_RC_TOKEN_THEME }, { 209, GTK_RC_TOKEN_RC }, { 212, GTK_RC_TOKEN_HIGHEST }, { 220, GTK_RC_TOKEN_ENGINE }, { 227, GTK_RC_TOKEN_MODULE_PATH }, { 239, GTK_RC_TOKEN_STOCK }, { 245, GTK_RC_TOKEN_IM_MODULE_FILE }, { 260, GTK_RC_TOKEN_LTR }, { 264, GTK_RC_TOKEN_RTL }, { 268, GTK_RC_TOKEN_COLOR }, { 274, GTK_RC_TOKEN_UNBIND } }; static GHashTable *realized_style_ht = NULL; static gchar *im_module_file = NULL; static gchar **gtk_rc_default_files = NULL; /* RC file handling */ static gchar * gtk_rc_make_default_dir (const gchar *type) { const gchar *var; gchar *path; var = g_getenv ("GTK_EXE_PREFIX"); if (var) path = g_build_filename (var, "lib", "gtk-3.0", GTK_BINARY_VERSION, type, NULL); else path = g_build_filename (_gtk_get_libdir (), "gtk-3.0", GTK_BINARY_VERSION, type, NULL); return path; } /** * gtk_rc_get_im_module_path: * * Obtains the path in which to look for IM modules.
