Detailed Description

Derived from TEventHandler and TStreamableBase, TWindow is the parent class for all window classes. It represents the functionality common to all windows, whether they are dialog boxes, controls, multiple document interface (MDI) windows, or layout windows. One of the fundamental ObjectWindows classes that implements OLE functionality, TOleWindow, provides support for embedding objects in a compound document application.

Typedef Documentation

typedef void(* owl::TActionFunc)(TWindow *win, void *param)

Defines the signature of the callback function passed to the ForEach method of TWindow.

typedef void(TWindow::* owl::TActionMemFunc)(TWindow *win, void *param)

Defines the signature of the callback function passed to the ForEach method of TWindow.

typedef bool(* owl::TCondFunc)(TWindow *win, void *param)

Defines the signature of the callback function used by the FirstThat function of TWindow.

typedef bool(TWindow::* owl::TCondMemFunc)(TWindow *win, void *param)

Defines the signature of the member function used by the FirstThat function of TWindow.

Enumeration Type Documentation

enum owl::TEventStatus

Mixin window event implementation return status.

Event status constants indicate the status of a mix-in window event implementation, for example, a keyboard event. The TEventStatus constants indicate whether or not additional handlers are needed.

Enumerator:

esPartial	Additional handlers may be invoked.
esComplete	No additional handlers are needed.

enum owl::TTransferDirection

The TTransferDirection enum describes the constants that the transfer function uses to determine how to transfer data to and from the transfer buffer

Enumerator:

tdGetData	Get data from the window into the buffer.
tdSetData	Set data from the buffer into the window.
tdSizeData	Return the size of data transferred by the class.

enum owl::TWindowFlag

Define bit masks for the internally used flag attributes of TWindow.

Enumerator:

wfAlias	TWindow is an alias to a preexisting HWND.
wfAutoCreate	Create the HWND when our parent is created.
wfFromResource	Handle comes from HWND created from resource.
wfShrinkToClient	Shrink a frame window to its client's size.
wfMainWindow	This frame window is the main window.
wfFullyCreated	Window is fully created & not being destroyed.
wfStreamTop	This window is the topmost one to stream.
wfPredefinedClass	Window class used belongs to a predefined Windows class and was not defined by OWL.
wfTransfer	Participates in the Transfer mechanism.
wfUnHidden	Used temporarily when destroying MDI child.
wfUnDisabled	Used temporarily when destroying MDI child.
wfDeleteOnClose	Window is condemned on EvClose. Indicates that a modeless dialog's pointer is to be deleted when it receives a WM_CLOSE message, causing its class's destructor to be called immediately. Default behavior is to leave the dialog pointer alone. Setting this flag has no effect on modal dialogs. To set this flag for a modeless dialog object, add the following statement to the constructor of your TDialog-derived class: < SetFlag(wfDeleteOnClose); <
wfPropagateIdle	Pass down IdleAction.
wfModalWindow	Was created via TWindow::Execute.
wfDetached	Window handle has been detached.
wfInsertAtEdge	(Decoration) Window to be inserted against frame's edge
