Description

TeplSettings is a singleton class to have a central access to some GSettings objects and having convenience features that are useful for a text editor.

The central access permits to:

  • Share the same GSettings objects between different parts of the application.

  • Avoid the need to store GSettings objects a bit everywhere in different classes.

Functions

tepl_settings_get_singleton ()

TeplSettings *
tepl_settings_get_singleton (void);

Returns

the TeplSettings singleton instance.

tepl_settings_peek_desktop_interface_settings ()

GSettings *
tepl_settings_peek_desktop_interface_settings
                               (TeplSettings *self);

Parameters

self

the TeplSettings instance.

 

Returns

the GSettings for "org.gnome.desktop.interface".

tepl_settings_provide_font_settings ()

void
tepl_settings_provide_font_settings (TeplSettings *self,
                                     GSettings *font_settings,
                                     const gchar *use_default_font_key,
                                     const gchar *editor_font_key);

This function can only be called once, to provide two keys:

  • use_default_font_key : must be of type boolean, to know whether to use the system's font (the default font), or the editor font.

  • editor_font_key : must be of type string, containing the font name to have a different font for the text editor, rather than using the system's font.

See tepl_settings_get_selected_font().

Parameters

self

the TeplSettings instance.

 

font_settings

the GSettings object containing the keys.

 

use_default_font_key

a key of type boolean.

 

editor_font_key

a key of type string.

 

Since: 6.2


tepl_settings_get_selected_font ()

gchar *
tepl_settings_get_selected_font (TeplSettings *self);

If tepl_settings_provide_font_settings() has *not* been called, this function always returns the current value of the system's fixed width (monospace) font.

If tepl_settings_provide_font_settings() *has* been called, this function returns the font name depending on the boolean value of use_default_font_key .

See also the “font-changed” signal, tepl_utils_override_font_string() and tepl_prefs_create_font_component().

Parameters

self

the TeplSettings instance.

 

Returns

the selected font name.

Since: 6.2


tepl_settings_handle_theme_variant ()

void
tepl_settings_handle_theme_variant (TeplSettings *self,
                                    GSettings *theme_variant_settings,
                                    const gchar *theme_variant_setting_key);

This function permits to setup correctly the GTK theme variant to use.

If theme_variant_settings and theme_variant_setting_key are NULL, only the system's settings will be taken into account.

If theme_variant_settings and theme_variant_setting_key are provided, they are taken into account according to TeplSettingsThemeVariant.

You should call this function only once, as subsequent calls are ignored (the setting used cannot be reconfigured).

Parameters

self

the TeplSettings instance.

 

theme_variant_settings

a GSettings object, or NULL.

[nullable]

theme_variant_setting_key

a GSettings key of type enum TeplSettingsThemeVariant, or NULL.

[nullable]

tepl_settings_provide_style_scheme_settings ()

void
tepl_settings_provide_style_scheme_settings
                               (TeplSettings *self,
                                GSettings *style_scheme_settings,
                                const gchar *key_for_light_theme_variant,
                                const gchar *key_for_dark_theme_variant);

This function can only be called once, to provide two keys:

  • key_for_light_theme_variant : must be of type string, containing the ID of a GtkSourceStyleScheme that should be used when the GTK theme variant is light.

  • key_for_dark_theme_variant : the same, but when the GTK theme variant is dark.

See tepl_settings_get_style_scheme_id().

Parameters

self

the TeplSettings instance.

 

style_scheme_settings

the GSettings object containing the keys.

 

key_for_light_theme_variant

a key of type string.

 

key_for_dark_theme_variant

a key of type string.

 

Since: 6.11


tepl_settings_get_style_scheme_id ()

gchar *
tepl_settings_get_style_scheme_id (TeplSettings *self);

Parameters

self

the TeplSettings instance.

 

Returns

the value of the “style-scheme-id” property.

[transfer full][nullable]

tepl_settings_get_range_uint ()

gboolean
tepl_settings_get_range_uint (GSettings *settings,
                              const gchar *key,
                              guint32 *min,
                              guint32 *max);

This function introspects a GSettings key to get its range, if the key as a "u" type (unsigned integer). FALSE is returned if the introspection failed.

See g_settings_schema_key_get_range() for more flexibility.

Parameters

settings

a GSettings.

 

key

a key part of settings .

 

min

the minimum value allowed by the range.

[out]

max

the maximum value allowed by the range.

[out]

Returns

whether the operation was successful.

Since: 6.2

Property Details

The “style-scheme-id” property

  “style-scheme-id”          char *

See tepl_settings_provide_style_scheme_settings().

The value of this property depends on whether the GTK theme is light or dark, and uses the corresponding GSettings key.

Owner: TeplSettings

Flags: Read

Default value: NULL

Since: 6.11

Signal Details

The “font-changed” signal

void
user_function (TeplSettings *settings,
               gpointer      user_data)

The ::font-changed signal is emitted when the return value of tepl_settings_get_selected_font() has potentially changed.

It takes into account the use_default_font_key provided with tepl_settings_provide_font_settings() to avoid unnecessary signal emission. In other words, for example if use_default_font_key is FALSE, the signal is not emitted even if the default (system's) font has been modified.

The relation between this signal and a potential zoom in and zoom out feature, to temporarily make the font larger or smaller (so the zoom level not being stored in GSettings): when this signal is emitted, it means that the user has explicitly changed the font setting, and as such he or she probably wants to use that font instead. So the expected behavior in that case is to reset the zoom level. But it's left as an exercise for another class, since TeplSettings is only for GSettings.

Parameters

settings

the TeplSettings emitting the signal.

 

user_data

user data set when the signal handler was connected.

 

Flags: Run First
