kinds of files; useful in file selection dialogs. Simple example showing FileFilter within the FileChooserDialog example:
public class MainWindow: Gtk.Window {
protected virtual void OnBtnLoadFileClicked(object sender, System.EventArgs e)
{
Gtk.FileChooserDialog fc=
new Gtk.FileChooserDialog("Choose the file to open",
this,
FileChooserAction.Open,
Gtk.Stock.Cancel,ResponseType.Cancel,
Gtk.Stock.Open,ResponseType.Accept);
//filter begins here...
FileFilter filter = new FileFilter();
filter.Name = "PNG and JPEG images";
filter.AddMimeType("image/png");
filter.AddPattern("*.png");
filter.AddMimeType("image/jpeg");
filter.AddPattern("*.jpg");
fc.AddFilter(filter);
//second filter
filter = new FileFilter();
filter.Name = "PNG Images (*.png)";
filter.AddMimeType("image/png");
filter.AddPattern("*.png");
fc.AddFilter(filter);
//end filter code
if (fc.Run() == (int)ResponseType.Accept)
{
System.Console.WriteLine
}
//Don't forget to call Destroy() or the FileChooserDialog window won't get closed.
fc.Destroy();
}
ConstructorCreates a new file filter with no rules attached to it.
A newly-created filter doesn't accept any files, so is not
particularly useful until you add rules with
,
, or
.
Constructor
a Constructor for internal use only.MethodSystem.Void
a
a Adds a rule to a filter that allows files based on a custom callback function.
The bitfield which is passed in provides information
about what sorts of information that the filter function needs;
this allows GTK+ to avoid retrieving expensive information when
it isn't needed by the filter.
MethodSystem.Void
a Adds a rule allowing a given MIME type to a filter.MethodSystem.Void
a Adds a rule allowing a shell style glob to a filter.MethodSystem.VoidTo be addedTo be addedMethodSystem.Boolean
a Tests whether a file should be displayed according to this filter.a , TRUE if the file should be displayed.

PropertyGLib.GTypeThe of this object.a PropertySystem.StringThe human-readable name of the filter.a
This is the string that will be displayed in the file selector
user interface if there is a selectable list of filters.
PropertyGtk.FileFilterFlags
