promptSetText
Set the text entered by the user in the dialog.
This method is used for %WEBKIT_SCRIPT_DIALOG_PROMPT dialogs when #WebKitWebView::script-dialog signal is emitted to set the text entered by the user. The default implementation of #WebKitWebView::script-dialog signal sets the text of the entry form when OK button is clicked, otherwise null is set. It's an error to use this method with a #WebKitScriptDialog that is not of type %WEBKIT_SCRIPT_DIALOG_PROMPT.
Parameters
text
the text to set
