Description

A gtk.RecentFilter can be used to restrict the files being shown in a gtk.RecentChooser. Files can be filtered based on their name (with the gtk.RecentFilter.add_pattern() method), on their mime type (with the gtk.FileFilter.add_mime_type() method), on the application that has registered them (with the gtk.RecentFilter.add_application() method), or by a custom filter function (with the gtk.RecentFilter.add_custom() method).

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 gtk.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 gtk.RecentChooser, see the gtk.RecentChooser.add_filter() method, but it is also possible to manually use a filter on a file with the gtk.RecentFilter.filter() method.

Recently used files are supported since GTK+ 2.10.

Constructor

gtk.RecentFilter

    gtk.RecentFilter()

Returns :

a new gtk.RecentFilter

Note

This constructor is available in PyGTK 2.10 and above.

Creates a new gtk.RecentFilter with no rules added to it. Such a filter does not accept any recently used resources, so is not particularly useful until you add rules with the gtk.RecentFilter.add_pattern(), gtk.RecentFilter.add_mime_type(), gtk.RecentFilter.add_application(), gtk.RecentFilter.add_age() methods. To create a filter that accepts any recently used resource, use:

      filter = gtk.RecentFilter()
      filter.add_pattern("*")
      

Methods

gtk.RecentFilter.set_name

    def set_name(name)

name :

the human readable name

Note

This method is available in PyGTK 2.10 and above.

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.

gtk.RecentFilter.get_name

    def get_name()

Returns :

the name of the filter, or None.

Note

This method is available in PyGTK 2.10 and above.

Returns the human-readable name for the filter. See the gtk.RecentFilter.set_name() method.

gtk.RecentFilter.add_mime_type

    def add_mime_type(mime_type)

mime_type :

a MIME type

Note

This method is available in PyGTK 2.10 and above.

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

gtk.RecentFilter.add_pattern

    def add_pattern(pattern)

pattern :

a file pattern

Note

This method is available in PyGTK 2.10 and above.

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

gtk.RecentFilter.add_pixbuf_formats

    def add_pixbuf_formats()

Note

This method is available in PyGTK 2.10 and above.

Adds a rule that filters image files based on the formats supported by gtk.gdk.Pixbuf.

gtk.RecentFilter.add_application

    def add_application(application)

application :

an application name

Note

This method is available in PyGTK 2.10 and above.

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

gtk.RecentFilter.add_group

    def add_group(group)

group :

a group name

Note

This method is available in PyGTK 2.10 and above.

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

gtk.RecentFilter.add_age

    def add_age(days)

days :

number of days

Note

This method is available in PyGTK 2.10 and above.

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

gtk.RecentFilter.add_custom

    def add_custom(needed, func, data)

needed :

a combination of the GTK Recent Filter Flags indicating the information that the custom filter function needs.

func :

callback function; if the function returns True, then the file will be displayed.

data :

data to pass to func

Note

This method is available in PyGTK 2.10 and above.

Adds a rule to a filter that filters resources based on a custom callback function. needed is a combination of the GTK Recent Filter Flags which provides information about what sorts of information that the filter function needs; this allows PyGTK to avoid retrieving expensive information when it isn't needed by the filter.

The signature of the filter function is:

  def func(filterinfo, user_data):
      

where filterinfo is a dict containing the info requested by needed as key-value pairs and user_data is data. The possible filterinfo keys are: "uri", "display_name", "mime_type", "applications", "age" and "groups".

gtk.RecentFilter.get_needed

    def get_needed()

Returns :

a combination of the GTK Recent Filter Flags indicating what fields are used for filtering when calling the gtk.RecentFilter.filter() method

Note

This method is available in PyGTK 2.10 and above.

Returns a combination of the GTK Recent Filter Flags indicating what fields are used for filtering.

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

gtk.RecentFilter.filter

    def filter(filter_info)

filter_info :

a filter info dict containing information about a recently used resource

Returns :

True if the file should be displayed

Note

This method is available in PyGTK 2.10 and above.

Returns True if a file should be displayed. filter_info is a dict that should include the key-value pairs as specified by the return flags from the gtk.RecentFilter.get_needed() method. The possible filter_info keys are: "uri", "display_name", "mime_type", "applications", "age" and "groups".

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