openfiledialog Asynchronous
Let the user choose one file through Android's picker. This is the right entry point for importing a document outside Kawaii's workspace.
Luau
openfiledialog(options: FileDialogOptions?) -> Document?Parameters
| Parameter | Type | Description |
|---|---|---|
options | FileDialogOptions? | Optional FileDialogOptions table; use its named fields to guide the system picker. |
Argument fields
Luau
FileDialogOptions = {
defaultPath: string?, title: string?, extensionFilter: {string}?,
suggestedName: string?, defaultExtension: string?
}| Field | Description |
|---|---|
defaultPath | Initial picker location. The Android picker uses this only when it is a content:// URI. |
title | Optional chooser title for open dialogs. It is not used as the save filename. |
extensionFilter | Array of extensions, such as {"txt", "json"}. Known extensions are converted to MIME filters; unknown-only filters allow all types. Folder dialogs do not use this filter. |
suggestedName | Suggested filename for savefiledialog. Defaults to untitled when omitted or empty. |
defaultExtension | Extension appended to the suggested save filename when it does not already have that extension. Leading dots are removed. |
Returns
Document?A Document for the chosen file, or nil if the picker is cancelled.
Usage notes
A Document is a handle to the user-selected location, not a workspace path. Call methods with a colon and keep the handle for later operations.
Cancellation is expected user input; check for nil before reading.
Example
Luau
local document = openfiledialog({ title = "Choose settings" })
if document then
print("Importing", document:GetName())
print(document:Read())
end
