Detailed Description

A GtkFileFilter can be used to restrict the files being shown in a GtkFileChooser. Files can be filtered based on their name (with gtkFileFilterAddPattern), on their mime type (with gtkFileFilterAddMimeType), or by a custom filter function (with gtkFileFilterAddCustom).

Filtering by mime types 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 GtkFileFilter 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 GtkFileChooser, see gtkFileChooserAddFilter, but it is also possible to manually use a filter on a file with gtkFileFilterFilter.

Structures

GtkFileFilter
The GtkFileFilter struct contains only private fields and should not be directly accessed.

GtkFileFilterInfo
A GtkFileFilterInfo struct is used to pass information about the tested file to gtkFileFilterFilter. GtkFileFilterInfo is a transparent-type.

contains
[GtkFileFilterFlags] Flags indicating which of the following fields need are filled
filename
[character] the filename of the file being tested
uri
[character] the URI for the file being tested
displayName
[character] the string that will be used to display the file in the file chooser
mimeType
[character] the mime type of the file

Convenient Construction

gtkFileFilter is the equivalent of gtkFileFilterNew.

Enums and Flags

GtkFileFilterFlags
These flags indicate what parts of a GtkFileFilterInfo struct are filled or need to be filled.

filename
the filename of the file being tested
uri
the URI for the file being tested
display-name
the string that will be used to display the file in the file chooser
mime-type
the mime type of the file

User Functions

GtkFileFilterFunc(filter.info, data)
The type of function that is used with custom filters, see gtkFileFilterAddCustom.

filter.info
[GtkFileFilterInfo] a GtkFileFilterInfo that is filled according to the needed flags passed to gtkFileFilterAddCustom
data
[R object] user data passed to gtkFileFilterAddCustom

Returns: [logical] TRUE if the file should be displayed
