Detailed Description

Typically used to obtain information from a user, a dialog box is a window inside of which other controls such as buttons and scroll bars can appear.

Unlike actual child windows which can only be displayed in the parent window's client area, dialog boxes can be moved anywhere on the screen. TDialog objects represent both modal and modeless dialog box interface elements. (A modal dialog box disables operations in its parent window while it is open, and, thus, lets you function in only one window "mode.")

A TDialog object has a corresponding resource definition that describes the placement and appearance of its controls. The identifier of this resource definition is supplied to the constructor of the TDialog object. A TDialog object is associated with a modal interface element by calling its Execute member function and with a modeless interface element by calling its Create member function.

You can use TDialog to build an application that uses a dialog as its main window by constructing your dialog as a TDialog and passing it as the client of a TFrameWindow. Your code might look something like this:

SetMainWindow(new TFrameWindow(0, "title" new TDialog(0, IDD_MYDIALOG)));

TDialog is a streamable class.

ObjectWindows also encapsulates common dialog boxes that let the user select font, file name, color, print options, and so on. TCommonDialog is the parent class for this group of common dialog box classes.

Constructor & Destructor Documentation

TDialog() [1/3]

owl::TDialog::TDialog	(	TWindow *	parent,
		TResId	resId,
		TModule *	module = nullptr )

Constructor for a TDialog object.

Takes an TResId for its template name or numeric Id Invokes a TWindow constructor, passing parent and module, and calls DisableAutoCreate to prevent TDialog from being automatically created and displayed along with its parent. TDialog then initializes the caption to 0 and sets TDialogAttr.Name using the dialog box's integer or string resource identifier which must correspond to a dialog resource definition in the resource file. Note that resId may be 0, e.g. when TDialog encapsulates a common dialog.

Finally, it initializes TDialogAttr.Param to 0 and clear the flag dfIsModal, and if OWL5_COMPAT is defined IsModal is set to false.

TDialog() [2/3]

owl::TDialog::TDialog ( TWindow * parent, const DLGTEMPLATE & dlgTemplate, TAutoDelete del = AutoDelete, TModule * module = nullptr )

explicit

Takes an pointer to dialog template.

Invokes a TWindow constructor, passing parent and module, and calls DisableAutoCreate to prevent TDialog from being automatically created and displayed along with its parent. TDialog then initializes the caption to 0 and sets TDialogAttr.Name using DLGTEMPLATE*.

Finally, it initializes TDialogAttr.Param to 0 and clear the flag dfIsModal, and if OWL5_COMPAT is defined IsModal is set to false.

TDialog() [3/3]

owl::TDialog::TDialog ( HGLOBAL hTemplate, TWindow * parent, TAutoDelete del = AutoDelete, TModule * module = nullptr )

explicit

Invokes a TWindow constructor, passing parent and module, and calls DisableAutoCreate to prevent TDialog from being automatically created and displayed along with its parent.

TDialog then initializes the caption to 0 and sets TDialogAttr.Name using DLGTEMPLATE*.

Finally, it initializes TDialogAttr.Param to 0 and clear the flag dfIsModal, and if OWL5_COMPAT is defined IsModal is set to false.

~TDialog()

owl::TDialog::~TDialog ( )

override

Destructor for a TDialog.

If DialogAttr.Name is a string and not an integer resource identifier, this destructor frees memory allocated to DialogAttr.Name, which holds the name of the dialog box.

Member Function Documentation

CloseWindow()

void owl::TDialog::CloseWindow ( int retValue = IDCANCEL )

overridevirtual

Overrides the virtual function defined by TWindow and conditionally shuts down the dialog box.

If the dialog box is modeless, it calls TWindow::CloseWindow(), passing retValue.

If the dialog box is modal, it calls CanClose(). If CanClose() returns true, CloseWindow() calls TransferData() to transfer dialog box data, and shuts down, passing retValue.

Note

The default value of retValue is IDCANCEL.

Reimplemented from owl::TWindow.

Create()

bool owl::TDialog::Create ( ) -> bool

overridevirtual

Creates a modeless dialog box interface element associated with the TDialog object.

Registers all the dialog's child windows for custom control support. Calls PerformCreate to perform the actual creation of the dialog box. Create returns true if successful. If unsuccessful, Create throws a TXInvalidWindow exception.

Destroy()

void owl::TDialog::Destroy ( int retValue = IDCANCEL )

overridevirtual

Destroys the interface element associated with the TDialog object.

If the element is a modeless dialog box or enabled Emulation of ModlaDialog , Destroy calls TWindow::Destroy. If the element is a modal dialog box, Destroy calls EnableAutoCreate on all child windows. Then Destroy calls the Windows function ::EndDialog, passing retValue as the value returned to indicate the result of the dialog's execution. The default retValue is IDCANCEL.

DialogFunction()

INT_PTR owl::TDialog::DialogFunction ( TMsgId msg, TParam1 param1, TParam2 param2 )

virtual

Override this to process messages within the dialog function.

The default dialog function.

For most messages, 1 should be returned if the message is handled, and 0 if it is not. Some special messages require a message-specific return value other than this: WM_CHARTOITEM, WM_COMPAREITEM, WM_CTL*, WM_INITDIALOG, WM_QUERYDRAGICON and WM_VKEYTOITEM. See the Windows API documentation for details.

Handles the two mesages, WM_INITDIALOG and WM_SETFONT that may be passed to us without sending, or sent before we get a chance to thunk DIALOG's window proc. EvInitDialog() is called as a virtual function, while EvSetFont() is dispatched to. To process messages within the dialog function, your application must override this function. DialogFunction returns true if the message is handled and false if the message is not handled.

DoExecute()

int owl::TDialog::DoExecute ( ) -> int

Execute()

int owl::TDialog::Execute ( ) -> int

overridevirtual

Creates and executes a modal dialog box interface element associated with the TDialog object.

If the element is successfully associated, Execute does not return until the TDialog is closed.

Execute performs the following tasks:

1. Registers this dialog's window class and all of the dialog's child windows.
2. Calls TDialog::DoExecute to execute the dialog box.

Execute returns an integer value that indicates how the user closed the modal dialog box. This will normally be IDOK or IDCANCEL, but the value may be customized by derived dialog classes.

If the dialog class cannot be registered (TWindow::Register returns false), or the execution of the dialog fails (TDialog::DoExecute returns -1), then Execute throws the TXWindow exception.

Note

Derived dialog classes may need to communicate errors apart from window creation failure. The derived class may throw other exceptions, return other error codes, or set custom error states. For example, the classes TFileOpenDialog and TFileSaveDialog will set the associated TOpenSaveDialog::TData::Error state to indicate any errors, such as buffer overflow. In general, client code should be aware of any error handling defined by the derived class. Do not assume that a return value of IDOK means success.

For example:

TOpenSaveDialog::TData data{...};
TFileOpenDialog dlg{this, data};
const auto r = dlg.Execute();
if (data.Error != 0)
{ 
  // ...Handle error...
}
else if (r == IDOK)
{
  // ...Open file...
}

StdDlgProc()

INT_PTR CALLBACK owl::TDialog::StdDlgProc ( HWND hDlg, UINT msg, WPARAM param1, LPARAM param2 )

Callback procs for hooking TDialog to native window.

Handles messages that come from the window procedure of dialogs (WC_DIALOG's wndProc).

If DlgCreationWindow is not 0, then msg is destined for DlgCreationWindow. When StdDlgProc first receives a message, it checks to see if it needs to associate the global C++ variable DlgCreationWindow with the one passed in HWND. If it needs to do that, it will then subclass the window procedure. It calls the virtual DialogFunction() to handle specific messages, mostly for the startup sequence. Any exception within this function is suspended by TApplication::SuspendThrow.
