FileDialog (original) (raw)

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

Inherited By: EditorFileDialog

A dialog for selecting files or directories in the filesystem.

Description

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.

Note: FileDialog is invisible by default. To make it visible, call one of the popup_* methods from Window on the node, such as Window.popup_centered_clamped().

• void set_access(value: Access)

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

The available file type filters. Each filter string in the array should be formatted like this: *.png,*.jpg,*.jpeg;Image Files;image/png,image/jpeg. The description text of the filter is optional and can be omitted. Both file extensions and MIME type should be always set.

Note: Embedded file dialogs and Windows file dialogs support only file extensions, while Android, Linux, and macOS file dialogs also support MIME types.

• 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 for Android 10+ devices and 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.

Note: This property is ignored in EditorFileDialog.

Method Descriptions

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

Adds a comma-separated file extension filter and comma-separated MIME type mime_type 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", a mime_type of image/png, image/jpeg, and a description of "Images" results in filter text "Images (*.png, *.jpg)".

Note: Embedded file dialogs and Windows file dialogs support only file extensions, while Android, Linux, and macOS file dialogs also support MIME types.

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.

PackedStringArray get_favorite_list() static 🔗

Returns the list of favorite directories, which is shared by all FileDialog nodes. Useful to store the list of favorites between project sessions. This method can be called only from the main thread.

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) const 🔗

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

String get_option_name(option: int) const 🔗

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

PackedStringArray get_option_values(option: int) const 🔗

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

PackedStringArray get_recent_list() static 🔗

Dictionary get_selected_options() const 🔗

Returns a Dictionary with the selected values of the additional OptionButtons and/or CheckBoxes. 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() 🔗

Invalidates and updates this dialog's content list.

Note: This method does nothing on native file dialogs.

bool is_customization_flag_enabled(flag: Customization) const 🔗

Returns true if the provided flag is enabled.

Shows the FileDialog using the default size and position for file dialogs, and selects the file name if there is a current file.

void set_customization_flag_enabled(flag: Customization, enabled: bool) 🔗

Sets the specified customization flag, allowing to customize the features available in this FileDialog.

void set_favorite_list(favorites: PackedStringArray) static 🔗

Sets the list of favorite directories, which is shared by all FileDialog nodes. Useful to restore the list of favorites saved with get_favorite_list(). This method can be called only from the main thread.

Note: FileDialog will update its internal ItemList of favorites when its visibility changes. Be sure to call this method earlier if you want your changes to have effect.

void set_get_icon_callback(callback: Callable) static 🔗

Sets the callback used by the FileDialog nodes to get a file icon, when DISPLAY_LIST mode is used. The callback should take a single String argument (file path), and return a Texture2D. If an invalid texture is returned, the file icon will be used instead.

void set_get_thumbnail_callback(callback: Callable) static 🔗

Sets the callback used by the FileDialog nodes to get a file icon, when DISPLAY_THUMBNAILS mode is used. The callback should take a single String argument (file path), and return a Texture2D. If an invalid texture is returned, the file_thumbnail icon will be used instead.

Thumbnails are usually more complex and may take a while to load. To avoid stalling the application, you can use ImageTexture to asynchronously create the thumbnail.

func _ready(): FileDialog.set_get_thumbnail_callback(thumbnail_method)

func thumbnail_method(path): var image_texture = ImageTexture.new() make_thumbnail_async(path, image_texture) return image_texture

func make_thumbnail_async(path, image_texture): var thumbnail_texture = await generate_thumbnail(path) # Some method that generates a thumbnail. image_texture.set_image(thumbnail_texture.get_image())
