Detailed Description

template<class T>
class wxPersistentWindow< T >

Base class for persistent windows.

Compared to wxPersistentObject this class does three things:

• Most importantly, wxPersistentWindow catches wxWindowDestroyEvent generated when the window is destroyed and saves its properties automatically when it happens.
• It implements GetName() using wxWindow::GetName() so that the derived classes don't need to do it.
• It adds a convenient wxPersistentWindow::Get() accessor returning the window object of the correct type.

Public Types
typedef T	WindowType
	The type of the associated window.
Public Member Functions
	wxPersistentWindow (WindowType *win)
	Constructor for a persistent window object.
WindowType *	Get () const
virtual wxString	GetName () const
	Implements the base class pure virtual method using wxWindow::GetName().

The type of the associated window.

Constructor & Destructor Documentation

template<class T>

wxPersistentWindow< T >::wxPersistentWindow

(

WindowType *

win

)

Constructor for a persistent window object.

The constructor uses wxEvtHandler::Connect() to catch wxWindowDestroyEvent generated when the window is destroyed and call wxPersistenceManager::SaveAndUnregister() when this happens. This ensures that the window properties are saved and that this object itself is deleted when the window is.

template<class T>

const [inline]

template<class T>

virtual wxString wxPersistentWindow< T >::GetName

(

)

const [virtual]

Implements the base class pure virtual method using wxWindow::GetName().

Notice that window names are usually not unique while this function must return a unique (at least among the objects of this type) string. Because of this you need to specify a non-default window name in its constructor when creating it or explicitly call wxWindow::SetName() before saving or restoring persistent properties.

Implements wxPersistentObject.
