WPEWebKit.WebView::script-dialog
Description: Reference for signal WPEWebKit.WebView::script-dialog

### Signal

# WPEWebKit WebView::script-dialog

#### Declaration

    gboolean
    script_dialog (
      WebKitWebView* self,
      WebKitScriptDialog* dialog,
      gpointer user_data
    )

#### Description [src]

Emitted when JavaScript code calls window.alert, window.confirm or window.prompt, or when onbeforeunload event is fired. The `dialog` parameter should be used to build the dialog. If the signal is not handled a different dialog will be built and shown depending on the dialog type: `WEBKIT_SCRIPT_DIALOG_ALERT`: message dialog with a single Close button. `WEBKIT_SCRIPT_DIALOG_CONFIRM`: message dialog with OK and Cancel buttons. `WEBKIT_SCRIPT_DIALOG_PROMPT`: message dialog with OK and Cancel buttons and a text entry with the default text. `WEBKIT_SCRIPT_DIALOG_BEFORE_UNLOAD_CONFIRM`: message dialog with Stay and Leave buttons.

It is possible to handle the script dialog request asynchronously, by simply caling `webkit_script_dialog_ref()` on the `dialog` argument and calling `webkit_script_dialog_close()` when done. If the last reference is removed on a `WebKitScriptDialog` and the dialog has not been closed, `webkit_script_dialog_close()` will be called.

Default handler: The default handler is called after the handlers added via `g_signal_connect()`.

#### Parameters

`dialog`

  Type: `WebKitScriptDialog`

  The `WebKitScriptDialog` to show.

  The data is owned by the caller of the function.

#### Return value

Type: `gboolean`

`TRUE` to stop other handlers from being invoked for the event. `FALSE` to propagate the event further.
