A dialog box is a window with a title bar and sometimes a system menu, which can be moved around
|
|
the screen. It can contain controls and other windows.

\wxheading{Remarks}
|
|
|
|
There are two kinds of dialog - {\it modal} and {\it modeless}. A modal dialog
|
|
blocks program flow and user input on other windows until it is dismissed, whereas a modeless dialog behaves more
|
|
like a frame in that program flow continues, and input on other windows is still possible.
|
|
You specify the type of dialog with the {\bf wxDIALOG\_MODAL} and {\bf wxDIALOG\_MODELESS} window
|
|
styles.
|
|
|
|
A dialog may be loaded from a wxWindows resource file (extension {\tt wxr}), which may itself
|
|
be created by Dialog Editor. For details,
|
|
see \helpref{The wxWindows resource system}{resourceformats}, \helpref{wxWindows resource functions}{resourcefuncs} and
|
|
the resource sample.
|
|
|
|
An application can define an \helpref{wxCloseEvent}{wxcloseevent} handler for the
|
|
dialog to respond to system close events.

\begin{twocollist}\itemsep=0pt
|
|
\twocolitem{\windowstyle{wxDIALOG\_MODAL}}{Specifies that the dialog box will be modal.}
|
|
\twocolitem{\windowstyle{wxCAPTION}}{Puts a caption on the dialog box.}
|
|
\twocolitem{\windowstyle{wxDEFAULT\_DIALOG\_STYLE}}{Equivalent to a combination of wxCAPTION, wxSYSTEM\_MENU and wxTHICK\_FRAME}
|
|
\twocolitem{\windowstyle{wxRESIZE\_BORDER}}{Display a resizeable frame around the window.}
|
|
\twocolitem{\windowstyle{wxSYSTEM\_MENU}}{Display a system menu.}
|
|
\twocolitem{\windowstyle{wxTHICK\_FRAME}}{Display a thick frame around the window.}
|
|
\twocolitem{\windowstyle{wxSTAY\_ON\_TOP}}{The dialog stays on top of all other windows (Windows only).}
|
|
\twocolitem{\windowstyle{wxNO\_3D}}{Under Windows, specifies that the child controls
|
|
should not have 3D borders unless specified in the control.}
|
|
\twocolitem{\windowstyle{wxDIALOG\_NO\_PARENT}}{By default, the dialogs crated
|
|
with {\tt NULL} parent window will be given the
|
|
\helpref{applications top level window}{wxappgettopwindow} as parent. Use this
|
|
style to prevent this from happening and create a really orphan dialog (note
|
|
that this is not recommended for modal dialogs).}
|
|
\twocolitem{\windowstyle{wxDIALOG\_EX\_CONTEXTHELP}}{Under Windows, puts a query button on the
|
|
caption. When pressed, Windows will go into a context-sensitive help mode and wxWindows will send
|
|
a wxEVT\_HELP event if the user clicked on an application window. {\it Note} that this is an extended
|
|
style and must be set by calling \helpref{SetExtraStyle}{wxwindowsetextrastyle} before Create is called (two-step construction).}
|
|
\end{twocollist}
|
|
|
|
Under Unix or Linux, MWM (the Motif Window Manager) or other window managers
|
|
reckognizing the MHM hints should be running for any of these styles to have an
|
|
effect.

|
|
a code to the application.

\docparam{iconize}{If TRUE, iconizes the dialog box; if FALSE, shows and restores it.}
|
|
|
|
\wxheading{Remarks}
|
|
|
|
Note that in Windows, iconization has no effect since dialog boxes cannot be
|
|
iconized. However, applications may need to explicitly restore dialog
|
|
boxes under Motif which have user-iconizable frames, and under Windows
|
|
calling {\tt Iconize(FALSE)} will bring the window to the front, as does
|
|
\rtfsp{\tt Show(TRUE)}.
|
|
|
|
\membersection{wxDialog::IsIconized}\label{wxdialogisiconized}
|
|
|
|
\constfunc{bool}{IsIconized}{\void}
|
|
|
|
Returns TRUE if the dialog box is iconized. Windows only.
|
|
|
|
\wxheading{Remarks}

|
\func{void}{OnCharHook}{\param{wxKeyEvent\&}{ event}}
|
|
|
|
This member is called to allow the window to intercept keyboard events
|
|
before they are processed by child windows.
|
|
|
|
%For more information, see \helpref{wxWindow::OnCharHook}{wxwindowoncharhook}
|
|
|
|
\wxheading{Remarks}
|
|
|
|
wxDialog implements this handler to fake a cancel command if the escape key has been
|
|
pressed. This will dismiss the dialog.
|
|
|
|
\membersection{wxDialog::OnApply}\label{wxdialogonapply}
|
|
|
|
\func{void}{OnApply}{\param{wxCommandEvent\& }{event}}
|
|
|
|
The default handler for the wxID\_APPLY identifier.
|
|
|
|
\wxheading{Remarks}
|
|
|
|
This function calls \helpref{wxWindow::Validate}{wxwindowvalidate} and \helpref{wxWindow::TransferDataToWindow}{wxwindowtransferdatatowindow}.
|
|

|
\membersection{wxDialog::OnCancel}\label{wxdialogoncancel}
|
|
|
|
\func{void}{OnCancel}{\param{wxCommandEvent\& }{event}}
|
|
|
|
The default handler for the wxID\_CANCEL identifier.
|
|
|
|
\wxheading{Remarks}
|
|
|
|
The function either calls {\bf EndModal(wxID\_CANCEL)} if the dialog is modal, or
|
|
sets the return value to wxID\_CANCEL and calls {\bf Show(FALSE)} if the dialog is modeless.
|
|
|
|

\helpref{wxDialog::OnOK}{wxdialogonok}, \helpref{wxDialog::OnApply}{wxdialogonapply}

\membersection{wxDialog::OnOK}\label{wxdialogonok}
|
|
|
|
\func{void}{OnOK}{\param{wxCommandEvent\& }{event}}
|
|
|
|
The default handler for the wxID\_OK identifier.
|
|
|
|
\wxheading{Remarks}
|
|
|
|
The function calls
|
|
\rtfsp\helpref{wxWindow::Validate}{wxwindowvalidate}, then \helpref{wxWindow::TransferDataFromWindow}{wxwindowtransferdatafromwindow}.
|
|
If this returns TRUE, the function either calls {\bf EndModal(wxID\_OK)} if the dialog is modal, or
|
|
sets the return value to wxID\_OK and calls {\bf Show(FALSE)} if the dialog is modeless.

|
|
|
|
\func{void}{OnSysColourChanged}{\param{wxSysColourChangedEvent\& }{event}}
|
|
|
|
The default handler for wxEVT\_SYS\_COLOUR\_CHANGED.
|
|
|
|
\wxheading{Parameters}
|
|
|
|
\docparam{event}{The colour change event.}
|
|
|
|
\wxheading{Remarks}
|
|
|
|
Changes the dialog's colour to conform to the current settings (Windows only).
|
|
Add an event table entry for your dialog class if you wish the behaviour
|
|
to be different (such as keeping a user-defined
|
|
background colour). If you do override this function, call wxEvent::Skip to
|
|
propagate the notification to child windows and controls.

|
|
|
|
\func{void}{SetModal}{\param{const bool}{ flag}}
|
|
|
|
{\bf NB:} This function is deprecated and doesn't work for all ports, just use
|
|
\helpref{ShowModal}{wxdialogshowmodal} to show a modal dialog instead.
|
|
|
|
Allows the programmer to specify whether the dialog box is modal (wxDialog::Show blocks control
|
|
until the dialog is hidden) or modeless (control returns immediately).
|
|
|
|
\wxheading{Parameters}
|
|
|
|
\docparam{flag}{If TRUE, the dialog will be modal, otherwise it will be modeless.}
|

|
|
|
\docparam{retCode}{The integer return code, usually a control identifier.}

|
|
|
\wxheading{Remarks}
|
|

|
A return code is normally associated with a modal dialog, where \helpref{wxDialog::ShowModal}{wxdialogshowmodal} returns
|
|
a code to the application. The function \helpref{wxDialog::EndModal}{wxdialogendmodal} calls {\bf SetReturnCode}.

|
|
modal, control is returned to the calling program.}
|
|
|
|
\wxheading{Remarks}
|
|
|
|

|
|
\helpref{wxDialog::EndModal}{wxdialogendmodal}.
