## Functions

### latexila_utils_file_query_exists_async ()

    void
    latexila_utils_file_query_exists_async
                                   (GFile *file,
                                    GCancellable *cancellable,
                                    GAsyncReadyCallback callback,
                                    gpointer user_data);

The asynchronous version of `g_file_query_exists()`. When the operation is finished, `callback` will be called. You can then call `latexila_utils_file_query_exists_finish()` to get the result of the operation.

#### Parameters

file | a GFile. |
cancellable | a GCancellable. |
callback | the callback to call when the operation is finished. |
user_data | the data to pass to the callback function. |

### latexila_utils_file_query_exists_finish ()

    gboolean
    latexila_utils_file_query_exists_finish
                                   (GFile *file,
                                    GAsyncResult *result);

Finishes the operation started with `latexila_utils_file_query_exists_async()`. There is no output GError parameter, so you should check if the operation has been cancelled (in which case `FALSE` will be returned).

#### Parameters

file | a GFile. |
result | a GAsyncResult. |

#### Returns

`TRUE` if the file exists and the operation hasn't been cancelled, `FALSE` otherwise.

### latexila_utils_create_parent_directories ()

    gboolean
    latexila_utils_create_parent_directories
                                   (GFile *file,
                                    GError **error);

Synchronously creates parent directories of `file` , so that `file` can be saved.

#### Parameters

file | a file |
error | a location to a `NULL` GError, or `NULL`. | [out][optional]

#### Returns

whether the directories are correctly created. `FALSE` is returned on error.

### latexila_utils_show_uri ()

    void
    latexila_utils_show_uri (GtkWidget *widget,
                             const gchar *uri,
                             guint32 timestamp,
                             GError **error);

Shows the `uri` . If the URI is a PDF file and if Evince is the default document viewer, this function also connects the Evince window so the backward search works (switch from the PDF to the source file).

#### Parameters

widget | the associated GtkWidget, or `NULL`. | [nullable]
uri | the URI to show. |
timestamp | a timestamp. |
error | a `NULL` GError, or `NULL`. | [out][optional]

### latexila_utils_get_dialog_component ()

    GtkWidget *
    latexila_utils_get_dialog_component (const gchar *title,
                                         GtkWidget *widget);

Gets a GtkDialog component. When a dialog contains several components, or logical groups, this function is useful to attach the `widget` with a `title` . The title will be in bold, left-aligned, and the widget will have a left margin.

#### Parameters

title | the title of the dialog component. |
widget | the widget displayed below the title. |

#### Returns

the dialog component containing the `title` and the `widget` .

### latexila_utils_join_widgets ()

    GtkWidget *
    latexila_utils_join_widgets (GtkWidget *widget_top,
                                 GtkWidget *widget_bottom);

Joins two widgets vertically, with junction sides.

#### Parameters

widget_top | the GtkWidget at the top. |
widget_bottom | the GtkWidget at the bottom. |

#### Returns

a GtkContainer containing `widget_top` and `widget_bottom` .

### latexila_utils_get_pixbuf_from_icon_name ()

    GdkPixbuf *
    latexila_utils_get_pixbuf_from_icon_name
                                   (const gchar *icon_name,
                                    GtkIconSize icon_size);

#### Parameters

icon_name | an icon name. |
icon_size | an icon size. |

#### Returns

the corresponding GdkPixbuf.

[nullable][transfer full]

### latexila_utils_register_icons ()

    void
    latexila_utils_register_icons (void);

Register the GNOME LaTeX icons to the GtkIconTheme as built-in icons. For example the icon located at data/images/stock-icons/badbox.png in the GNOME LaTeX git repository will be available with the icon name "badbox". The "stock-icons" directory name is for historical reasons and should be changed when stock icons are no longer used in GNOME LaTeX.

TODO: prefix icon names with "glatex-", so the badbox.png would be "glatex-badbox".

### latexila_utils_migrate_latexila_to_gnome_latex ()

    void
    latexila_utils_migrate_latexila_to_gnome_latex
                                   (void);

Migrates the GSettings values and user data/config files from LaTeXila to GNOME LaTeX, so that users don't lose all their settings.

TODO in >= 2025: delete this code.
