EventControllerFocus.connectEnter

gulong connectEnter(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.event_controller_focus.EventControllerFocus)))
   &&  Parameters!T.length <  2)

Connect to Enter signal.

Emitted whenever the focus enters into the widget or one of its descendents.

Note that this means you may not get an ::enter signal even though the widget becomes the focus location, in certain cases (such as when the focus moves from a descendent of the widget to the widget itself). If you are interested in these cases, you can monitor the propertyGtk.EventControllerFocus:is-focus property for changes.

`after`	Yes.After to execute callback after default handler, No.After to execute before (default)

Returns

Signal ID
