TWindow, derived from TEventHandler and TStreamableBase, provides window-specific behavior and encapsulates many functions that control window behavior and specify window creation and registration attributes.
TWindow is a generic window that can be resized and moved. You can construct an instance of TWindow, though normally you use TWindow as a base for your specialized window classes. In general, to associate and disassociate a TWindow object with a window element, you need to follow these steps:
The ObjectWindows destroy process consists of two parts: (1) call Destroy to destroy the interface element and (2) then delete the C++ object. However, it is perfectly valid to call Destroy on the interface element without deleting the C++ object and then to call Create at a later time to re-create the window. Because it is also valid to construct a C++ window object on the stack or as an aggregated member, the Destroy function cannot assume it should delete the C++ object.
The user-generated WM_CLOSE event handler, EvClose, also causes a C++ object to be deleted by passing the this pointer to the application. The C++ object is deleted automatically because the EvClose event frequently occurs in response to a user action, and this is the most convenient place for the deletion to take place. Later, when it's safe to do so, the application then deletes the window pointer. Because the stack often contains selectors that refer to the addresses of objects that may become invalid during the delete process, it is not safe to delete the this pointer while events are still being processed. If the addresses become invalid, they could cause trouble when they are reloaded from the stack.
TWindow is the base class for all window classes, including TFrameWindow, TControl, TDialog, and TMDIChild. The ObjectWindows hierarchy diagram shows the many classes that are derived from TWindow.

Constructs a TWindow that is used as an alias for a non-ObjectWindows window, and sets wfAlias.
Because the HWND is already available, this constructor, unlike the other TWindow constructor, performs the "thunking" and extraction of HWND information instead of waiting until the function Create creates the interface element.

Use this function to determine if it is okay to close a window.
Returns true if the associated interface element can be closed. Calls the CanClose member function of each of its child windows. Returns false if any of the CanClose calls returns false. In your application's main window, you can override TWindow's CanClose and call TWindow::MessageBox to display a YESNOCANCEL message prompting the user as follows:
YES Save the dataNO Do not save the data, but close the windowCANCEL Cancel the close operation and return to the edit windowThe following example shows how to write a CanClose function that displays a message box asking if the user wants to save a drawing that has changed. To save time, CanClose uses the IsDirty flag to see if the drawing has changed. If so, CanClose queries the user before closing the window.

| TResult owl::TWindow::DefaultProcessing | ( | ) |
Handles default processing of events, which includes continued processing of menu/accelerators commands and enablers, as well as notifications.
Serves as a general-purpose default processing function that handles a variety of messages. After being created and before calling DefaultProcessing, however, a window completes the following sequence of events (illustrated in the Default Message-Processing Flowchart).
If the incoming message is not a command or command enable message, WindowProc immediately searches the window's response table for a matching entry. If the incoming message is a command or command enable message, WindowProc calls EvCommand or EvCommandEnable. EvCommand and EvCommandEnable begin searching for a matching entry in the focus window's response table. If an entry is found, the corresponding function is dispatched; otherwise ObjectWindows calls DefaultProcessing to finish the recursive walk back up the parent chain, searching for a match until the receiving window (the window that initially received the message) is reached. At this point, one of the following actions occurs:
The following diagram illustrates this sequence of message-processing events:

If the background color (see TWindow::SetBkgndColor) is not set, or it has been set to TColor::None, then this function simply forwards the message to DefaultProcessing. The default processing uses the brush specified in the window class (WNDCLASS:hbrBackground) to clear the client area. If the background color is set to TColor::Transparent, no clearing is done, and the function simply returns true. Otherwise, the current background color is used to clear the client area, and true is returned, indicating no further erasing is required.
If you want to handle erasure in your Paint override, then override this handler and return false. Paint will then receive true in its erase parameter, and you must ensure that all of the background is painted within the invalidated region.

Returns the TWindowAttr structure, which contains the window's creation attributes.
Redefined by derived classes, GetWindowClass fills the supplied MS-Windows registration class structure with registration attributes, thus, allowing instances of TWindow to be registered.
This function, along with GetWindowClassName, allows Windows classes to be used for the specified ObjectWindows class and its derivatives. It sets the fields of the passed WNDCLASS parameter to the default attributes appropriate for a TWindow. The fields and their default attributes for the class are the following:
cbClsExtra 0 (the number of extra bytes to reserve after the Window class structure). This value is not used by ObjectWindows.cbWndExtra 0 (the number of extra bytes to reserve after the Window instance). This value is not used by ObjectWindows.hInstance The instance of the class in which the window procedure existshIcon 0 (Provides a handle to the class resource.) By default, the application must create an icon if the application's window is minimized.hCursor IDC_ARROW (provides a handle to a cursor resource)hbrBackground COLOR_WINDOW + 1 (the system background color)lpszMenuName 0 (Points to a string that contains the name of the class's menu.) By default, the windows in this class have no assigned menus.lpszClassName Points to a string that contains the name of the window class.lpfnWndProc The address of the window procedure. This value is not used by ObjectWindows.style Style field.The style field can contain one or more of the following values:
CS_BYTEALIGNCLIENT Aligns the window's client on a byte boundary in the x direction. This alignment, designed to improve performance, determines the width and horizontal position of the window.CS_BYTEALIGNWINDOW Aligns a window on a byte boundary in the x direction. This alignment, designed to improve performance, determines the width and horizontal position of the window.CS_CLASSDC Allocates a single device context (DC) that's going to be shared by all of the window in the class. This style controls how multi-threaded applications that have windows belonging to the same class share the same DC.CS_DBLCLKS Sends a double-click mouse message to the window procedure when the mouse is double-clicked on a window belonging to this class.CS_GLOBALCLASS Allows an application to create a window class regardless of the instance parameter. You can also create a global class by writing a DLL that contains the window class.CS_HREDRAW If the size of the window changes as a result of some movement or resizing, redraws the entire window.CS_NOCLOSE Disables the Close option on this window's system menu.CS_OWNDC Enables each window in the class to have a different DC.CS_PARENTDC Passes the parent window's DC to the child windows.CS_SAVEBITS Saves the section of the screen as a bitmap if the screen is covered by another window. This bitmap is later used to recreate the window when it is no longer obscured by another window.CS_VREDRAW If the height of the client area is changed, redraws the entire window.After the Windows class structure has been filled with default values by the base class, you can override this function to change the values of the Windows class structure. For example, you might want to change the window's colors or the cursor displayed.
Register unique classes for windows that want system background colors so that full-drag erasing uses the right color (NT fails to let window erase itself)

Default behavior for updating document title is to pass it to parent frame.
Stores the title of the document (docname). index is the number of the view displayed in the document's caption bar. In order to determine what the view number should be, SetDocTitle makes two passes: the first pass checks to see if there's more than one view, and the second pass, if there is more than one view, assigns the next number to the view. If there is only one view, index is 0; therefore, the document does not display a view number. When TDocument is checking to see if more than one view exists, index is -1. In such cases, only the document's title is displayed in the caption bar. SetDocTitle returns true if there is more than one view and TDocument displays the number of the view passed in index.

Performs setup following creation of an associated MS-Windows window.
The first virtual function called when the HWindow becomes valid. TWindow's implementation performs window setup by iterating through the child list, attempting to create an associated interface element for each child window object for which autocreation is enabled. (By default, autocreation is enabled for windows and controls, and disabled for dialog boxes.) If a child window cannot be created, SetupWindow calls TXWindow with an IDS_CHILDCREATEFAIL message.
If the receiver has a TScroller object, calls the scroller's SetBarRange() method.
SetupWindow can be redefined in derived classes to perform additional special initialization. Note that the HWindow is valid when the overridden SetupWindow is called, and that the children's HWindows are valid after calling the base classes' SetupWindow function.
The following example from the sample program, APPWIN.CPP, illustrates the use of an overridden SetupWindow to setup a window, initialize .INI entries, and tell Windows that we want to accept drag and drop transactions:

Sets the font that a control uses to draw text.
If the given font owns the underlying font handle (HFONT), the window will share ownership. If the given font does not own the handle, neither will the window. In any case, the given TFont object does not need to outlive the window. However, if the underlying font handle is not owned, the caller must make sure that the font handle outlives the window. In this last case, the call is equivalent to SetWindowFont (font.GetHandle(), redraw).

Transfers data to or from any window with or without children and returns the total size of the data transferred.
Transfer is a general mechanism for data transfer that can be used with or without using TransferData. The direction supplied specifies whether data is to be read from or written to the supplied buffer, or whether the size of the transfer data is simply to be returned. Data is not transferred to or from any child windows whose wfTransfer flag is not set. The return value is the size (in bytes) of the transfer data.

Transfers data between the TWindow's data buffer and the child windows in its ChildList (data is not transfered between any child windows whose wfTransfer flag is not set)

TransferData calls the Transfer member function of each participating child window, passing a pointer to TransferBuffer as well as the direction specified in direction (tdSetData, tdGetData, or tdSizeData).
