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

days	Number 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

application An 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

group A 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_type A 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

pattern A file pattern.

void Gtk::RecentFilter::add_pixbuf_formats ( )

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

Since gtkmm 2.10:

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 structure 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().

GtkRecentFilter* Gtk::RecentFilter::gobj ( )

inline

Provides access to the underlying C GtkObject.

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

inline

Provides access to the underlying C GtkObject.

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

name	Then human readable name of filter.

Gtk::RecentFilter* wrap	(	GtkRecentFilter *	object,
		bool	take_copy = `false`
	)

A Glib::wrap() method for this object.

Parameters

object	The C instance.
take_copy	False if the result should take ownership of the C instance. True if it should take a new copy or ref.

Returns: A C++ instance that wraps this C instance.
