FileDialog

继承： ConfirmationDialog < AcceptDialog < Window < Viewport < Node < Object

A dialog for selecting files or directories in the filesystem.

描述

FileDialog is a preset dialog used to choose files and directories in the filesystem. It supports filter masks. FileDialog automatically sets its window title according to the file_mode. If you want to use a custom title, disable this by setting mode_overrides_title to false.

信号

dir_selected ( dir: String )

Emitted when the user selects a directory.

file_selected ( path: String )

Emitted when the user selects a file by double-clicking it or pressing the OK button.

filename_filter_changed ( filter: String )

Emitted when the filter for file names changes.

files_selected ( paths: PackedStringArray )

Emitted when the user selects multiple files.

枚举

enum FileMode:

FileMode FILE_MODE_OPEN_FILE = 0

The dialog allows selecting one, and only one file.

FileMode FILE_MODE_OPEN_FILES = 1

The dialog allows selecting multiple files.

FileMode FILE_MODE_OPEN_DIR = 2

The dialog only allows selecting a directory, disallowing the selection of any file.

FileMode FILE_MODE_OPEN_ANY = 3

The dialog allows selecting one file or directory.

FileMode FILE_MODE_SAVE_FILE = 4

The dialog will warn when a file exists.

enum Access:

Access ACCESS_RESOURCES = 0

The dialog only allows accessing files under the Resource path (res://).

Access ACCESS_USERDATA = 1

The dialog only allows accessing files under user data path (user://).

Access ACCESS_FILESYSTEM = 2

The dialog allows accessing files on the whole file system.

属性说明

Access access = 0

• void set_access ( value: Access )
• Access get_access ( )

The file system access scope. See Access constants.

Warning: In Web builds, FileDialog cannot access the host file system. In sandboxed Linux and macOS environments, use_native_dialog is automatically used to allow limited access to host file system.

String current_dir

• void set_current_dir ( value: String )
• String get_current_dir ( )

The current working directory of the file dialog.

Note: For native file dialogs, this property is only treated as a hint and may not be respected by specific OS implementations.

String current_file

• void set_current_file ( value: String )
• String get_current_file ( )

The currently selected file of the file dialog.

String current_path

• void set_current_path ( value: String )
• String get_current_path ( )

The currently selected file path of the file dialog.

FileMode file_mode = 4

• void set_file_mode ( value: FileMode )
• FileMode get_file_mode ( )

The dialog's open or save mode, which affects the selection behavior. See FileMode.

String filename_filter = ""

• void set_filename_filter ( value: String )
• String get_filename_filter ( )

The filter for file names (case-insensitive). When set to a non-empty string, only files that contains the substring will be shown. filename_filter can be edited by the user with the filter button at the top of the file dialog.

See also filters, which should be used to restrict the file types that can be selected instead of filename_filter which is meant to be set by the user.

PackedStringArray filters = PackedStringArray()

• void set_filters ( value: PackedStringArray )
• PackedStringArray get_filters ( )

The available file type filters. Each filter string in the array should be formatted like this: *.txt,*.doc;Text Files. The description text of the filter is optional and can be omitted.

Note: For android native dialog, MIME types are used like this: image/*, application/pdf.

Note: The returned array is copied and any changes to it will not update the original property value. See PackedStringArray for more details.

bool mode_overrides_title = true

• void set_mode_overrides_title ( value: bool )
• bool is_mode_overriding_title ( )

If true, changing the file_mode property will set the window title accordingly (e.g. setting file_mode to FILE_MODE_OPEN_FILE will change the window title to "Open a File").

int option_count = 0

• void set_option_count ( value: int )
• int get_option_count ( )

The number of additional OptionButton s and CheckBox es in the dialog.

String root_subfolder = ""

• void set_root_subfolder ( value: String )
• String get_root_subfolder ( )

If non-empty, the given sub-folder will be "root" of this FileDialog, i.e. user won't be able to go to its parent directory.

Note: This property is ignored by native file dialogs.

bool show_hidden_files = false

• void set_show_hidden_files ( value: bool )
• bool is_showing_hidden_files ( )

If true, the dialog will show hidden files.

Note: This property is ignored by native file dialogs on Android and Linux.

bool use_native_dialog = false

• void set_use_native_dialog ( value: bool )
• bool get_use_native_dialog ( )

If true, and if supported by the current DisplayServer, OS native dialog will be used instead of custom one.

Note: On Android, it is only supported when using ACCESS_FILESYSTEM. For access mode ACCESS_RESOURCES and ACCESS_USERDATA, the system will fall back to custom FileDialog.

Note: On Linux and macOS, sandboxed apps always use native dialogs to access the host file system.

Note: On macOS, sandboxed apps will save security-scoped bookmarks to retain access to the opened folders across multiple sessions. Use OS.get_granted_permissions to get a list of saved bookmarks.

Note: Native dialogs are isolated from the base process, file dialog properties can't be modified once the dialog is shown.

方法说明

void add_filter ( filter: String, description: String = "" )

Adds a comma-delimited file name filter option to the FileDialog with an optional description, which restricts what files can be picked.

A filter should be of the form "filename.extension", where filename and extension can be * to match any string. Filters starting with . (i.e. empty filenames) are not allowed.

For example, a filter of "*.png, *.jpg" and a description of "Images" results in filter text "Images (*.png, *.jpg)".

void add_option ( name: String, values: PackedStringArray, default_value_index: int )

Adds an additional OptionButton to the file dialog. If values is empty, a CheckBox is added instead.

default_value_index should be an index of the value in the values. If values is empty it should be either 1 (checked), or 0 (unchecked).

void clear_filename_filter ( )

Clear the filter for file names.

void clear_filters ( )

Clear all the added filters in the dialog.

void deselect_all ( )

Clear all currently selected items in the dialog.

LineEdit get_line_edit ( )

Returns the LineEdit for the selected file.

Warning: This is a required internal node, removing and freeing it may cause a crash. If you wish to hide it or any of its children, use their CanvasItem.visible property.

int get_option_default ( option: int ) const¹

Returns the default value index of the OptionButton or CheckBox with index option.

String get_option_name ( option: int ) const¹

Returns the name of the OptionButton or CheckBox with index option.

PackedStringArray get_option_values ( option: int ) const¹

Returns an array of values of the OptionButton with index option.

Dictionary get_selected_options ( ) const¹

Returns a Dictionary with the selected values of the additional OptionButton s and/or CheckBox es. Dictionary keys are names and values are selected value indices.

VBoxContainer get_vbox ( )

Returns the vertical box container of the dialog, custom controls can be added to it.

Warning: This is a required internal node, removing and freeing it may cause a crash. If you wish to hide it or any of its children, use their CanvasItem.visible property.

Note: Changes to this node are ignored by native file dialogs, use add_option to add custom elements to the dialog instead.

void invalidate ( )

Invalidate and update the current dialog content list.

Note: This method does nothing on native file dialogs.

void set_option_default ( option: int, default_value_index: int )

Sets the default value index of the OptionButton or CheckBox with index option.

void set_option_name ( option: int, name: String )

Sets the name of the OptionButton or CheckBox with index option.

void set_option_values ( option: int, values: PackedStringArray )

Sets the option values of the OptionButton with index option.
