Detailed Description

RecentFilter can be used to restrict the files being shown in a RecentChooser.

Files can be filtered based on their name (with add_pattern()), on their mime type (with add_mime_type()), on the application that has registered them (with add_application()), or by a custom filter function (with add_custom()).

Filtering by mime type handles aliasing and subclassing of mime types; e.g. a filter for text/plain also matches a file with mime type application/rtf, since application/rtf is a subclass of text/plain. Note that RecentFilter allows wildcards for the subtype of a mime type, so you can e.g. filter for image/*.

Normally, filters are used by adding them to a RecentChooser, see RecentChooser::add_filter(), but it is also possible to manually use a filter on a file with filter().

Member Function Documentation

void Gtk::RecentFilter::add_age ( int  days)

Adds a rule that allows resources based on their age - that is, the number of days elapsed since they were last modified.

Since gtkmm 2.10:
Parameters
daysNumber of days.
void Gtk::RecentFilter::add_application ( const Glib::ustring &  application)

Adds a rule that allows resources based on the name of the application that has registered them.

Since gtkmm 2.10:
Parameters
applicationAn application name.
void Gtk::RecentFilter::add_custom ( RecentFilterFlags  needed,
const SlotCustom slot 
)
void Gtk::RecentFilter::add_group ( const Glib::ustring &  group)

Adds a rule that allows resources based on the name of the group to which they belong.

Since gtkmm 2.10:
Parameters
groupA group name.
void Gtk::RecentFilter::add_mime_type ( const Glib::ustring &  mime_type)

Adds a rule that allows resources based on their registered MIME type.

Since gtkmm 2.10:
Parameters
mime_typeA MIME type.
void Gtk::RecentFilter::add_pattern ( const Glib::ustring &  pattern)

Adds a rule that allows resources based on a pattern matching their display name.

Since gtkmm 2.10:
Parameters
patternA file pattern.
void Gtk::RecentFilter::add_pixbuf_formats ( )

Adds a rule allowing image files in the formats supported by GdkPixbuf.

Since gtkmm 2.10:
static Glib::RefPtr<RecentFilter> Gtk::RecentFilter::create ( )
static
Glib::ustring Gtk::RecentFilter::get_name ( ) const

Gets the human-readable name for the filter.

See set_name().

Since gtkmm 2.10:
Returns
The name of the filter, or nullptr. The returned string is owned by the filter object and should not be freed.
RecentFilterFlags Gtk::RecentFilter::get_needed ( ) const

Gets the fields that need to be filled in for the Gtk::RecentFilterInfo passed to filter()

This function will not typically be used by applications; it is intended principally for use in the implementation of Gtk::RecentChooser.

Since gtkmm 2.10:
Returns
Bitfield of flags indicating needed fields when calling filter().
static GType Gtk::RecentFilter::get_type ( )
static

Get the GType for this class, for use with the underlying GObject type system.

GtkRecentFilter* Gtk::RecentFilter::gobj ( )
inline

Provides access to the underlying C GObject.

const GtkRecentFilter* Gtk::RecentFilter::gobj ( ) const
inline

Provides access to the underlying C GObject.

GtkRecentFilter* Gtk::RecentFilter::gobj_copy ( )

Provides access to the underlying C instance. The caller is responsible for unrefing it. Use when directly setting fields in structs.

RecentFilter& Gtk::RecentFilter::operator= ( RecentFilter&&  src)
noexcept
void Gtk::RecentFilter::set_name ( const Glib::ustring &  name)

Sets the human-readable name of the filter; this is the string that will be displayed in the recently used resources selector user interface if there is a selectable list of filters.

Since gtkmm 2.10:
Parameters
nameThen human readable name of filter.
