WebView.connectScriptDialog

gulong connectScriptDialog(T)(T callback,  Flag!"After" after =  No.After) if (isCallable!T
    &&  is(ReturnType!T ==  bool)
   && (Parameters!T.length <  1 || (ParameterStorageClassTuple!T[0]  ==  ParameterStorageClass.none &&  is(Parameters!T[0]  ==  webkit.script_dialog.ScriptDialog)))
   && (Parameters!T.length <  2 || (ParameterStorageClassTuple!T[1]  ==  ParameterStorageClass.none &&  is(Parameters!T[1] :  webkit.web_view.WebView)))
   &&  Parameters!T.length <  3)

Connect to ScriptDialog signal.

Emitted when JavaScript code calls <function>window.alert</function>,

<function>window.confirm</function> or <function>window.prompt</function>,

or when <function>onbeforeunload</function> 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.types.ScriptDialogType.Alert]: message dialog with a single Close button.

</para></listitem> <listitem><para>

[webkit.types.ScriptDialogType.Confirm]: message dialog with OK and Cancel buttons.

</para></listitem> <listitem><para>

[webkit.types.ScriptDialogType.Prompt]: message dialog with OK and Cancel buttons and a text entry with the default text.

</para></listitem> <listitem><para>

[webkit.types.ScriptDialogType.BeforeUnloadConfirm]: message dialog with Stay and Leave buttons.

</para></listitem> </itemizedlist>

It is possible to handle the script dialog request asynchronously, by simply caling [webkit.script_dialog.ScriptDialog.ref_] on the dialog argument and calling [webkit.script_dialog.ScriptDialog.close] when done. If the last reference is removed on a #WebKitScriptDialog and the dialog has not been closed, [webkit.script_dialog.ScriptDialog.close] will be called.
