@Generated("org.javagi.JavaGI") public final class FileChooserRequest extends GObject

A request to open a file chooser.

Whenever the user interacts with an HTML input element with file type, WebKit will need to show a dialog to choose one or more files to be uploaded to the server along with the rest of the form data. For that to happen in a general way, instead of just opening a GtkFileChooserDialog (which might be not desirable in some cases, which could prefer to use their own file chooser dialog), WebKit will fire the WebKitWebView::run-file-chooser signal with a WebKitFileChooserRequest object, which will allow the client application to specify the files to be selected, to inspect the details of the request (e.g. if multiple selection should be allowed) and to cancel the request, in case nothing was selected.

In case the client application does not wish to handle this signal, WebKit will provide a default handler which will asynchronously run a regular GtkFileChooserDialog for the user to interact with.

  • Constructor Details

    • FileChooserRequest

      public FileChooserRequest(MemorySegment address)
      Create a FileChooserRequest instance for the provided memory address.
      Parameters:
      address - the memory address of the native object

    • FileChooserRequest

      public FileChooserRequest()
      Create a new FileChooserRequest.

  • Method Details

    • getType

      public static @Nullable Type getType()
      Get the GType of the FileChooserRequest class.
      Returns:
      the GType

    • getMemoryLayout

      public static MemoryLayout getMemoryLayout()
      The memory layout of the native struct.
      Returns:
      the memory layout

    • asParent

      protected FileChooserRequest asParent()
      Return this instance as if it were its parent type. Comparable to the Java super keyword, but ensures the parent typeclass is also used in native code.
      Overrides:
      asParent in class GObject
      Returns:
      the instance as if it were its parent type

    • cancel

      public void cancel()

      Ask WebKit to cancel the request.

      It's important to do this in case no selection has been made in the client, otherwise the request won't be properly completed and the browser will keep the request pending forever, which might cause the browser to hang.

    • getMimeTypes

      public String[] getMimeTypes()

      Get the list of MIME types the file chooser dialog should handle.

      Get the list of MIME types the file chooser dialog should handle, in the format specified in RFC 2046 for "media types". Its contents depend on the value of the 'accept' attribute for HTML input elements. This function should normally be called before presenting the file chooser dialog to the user, to decide whether to allow the user to select multiple files at once or only one.

      Returns:
      a null-terminated array of strings if a list of accepted MIME types is defined or null otherwise, meaning that any MIME type should be accepted. This array and its contents are owned by WebKit and should not be modified or freed.

    • getMimeTypesFilter

      public FileFilter getMimeTypesFilter()

      Get the filter currently associated with the request.

      Get the filter currently associated with the request, ready to be used by GtkFileChooser. This function should normally be called before presenting the file chooser dialog to the user, to decide whether to apply a filter so the user would not be allowed to select files with other MIME types.

      See webkit_file_chooser_request_get_mime_types() if you are interested in getting the list of accepted MIME types.

      Returns:
      a GtkFileFilter if a list of accepted MIME types is defined or null otherwise. The returned object is owned by WebKit should not be modified or freed.

    • getSelectMultiple

      public boolean getSelectMultiple()

      Whether the file chooser should allow selecting multiple files.

      Determine whether the file chooser associated to this WebKitFileChooserRequest should allow selecting multiple files, which depends on the HTML input element having a 'multiple' attribute defined.

      Returns:
      true if the file chooser should allow selecting multiple files or false otherwise.

    • getSelectedFiles

      public String[] getSelectedFiles()

      Get the list of selected files associated to the request.

      Get the list of selected files currently associated to the request. Initially, the return value of this method contains any files selected in previous file chooser requests for this HTML input element. Once webkit_file_chooser_request_select_files, the value will reflect whatever files are given.

      This function should normally be called only before presenting the file chooser dialog to the user, to decide whether to perform some extra action, like pre-selecting the files from a previous request.

      Returns:
      a null-terminated array of strings if there are selected files associated with the request or null otherwise. This array and its contents are owned by WebKit and should not be modified or freed.

    • selectFiles

      public void selectFiles(@Nullable String @Nullable [] files)
      Ask WebKit to select local files for upload and complete the request.
      Parameters:
      files - a null-terminated array of strings, containing paths to local files.

    • builder

      public static FileChooserRequest.Builder<? extends FileChooserRequest.Builder> builder()
      A FileChooserRequest.Builder object constructs a FileChooserRequest with the specified properties. Use the various set...() methods to set properties, and finish construction with FileChooserRequest.Builder.build().
      Returns:
      the builder object
