Assistant.connectApply

gulong connectApply(T)(T callback,  Flag!"After" after =  No.After) if (isCallable!T
    &&  is(ReturnType!T ==  void)
   && (Parameters!T.length <  1 || (ParameterStorageClassTuple!T[0]  ==  ParameterStorageClass.none &&  is(Parameters!T[0] :  gtk.assistant.Assistant)))

Connect to Apply signal.

The ::apply signal is emitted when the apply button is clicked.

The default behavior of the #GtkAssistant is to switch to the page after the current page, unless the current page is the last one.

A handler for the ::apply signal should carry out the actions for which the wizard has collected data. If the action takes a long time to complete, you might consider putting a page of type [gtk.types.AssistantPageType.Progress] after the confirmation page and handle this operation within the #GtkAssistant::prepare signal of the progress page.

Parameters

`callback`	signal callback delegate or function to connect `void callback(gtk.assistant.Assistant assistant)` `assistant` the instance the signal is connected to (optional)
`after`	Yes.After to execute callback after default handler, No.After to execute before (default)

Returns

Signal ID
