Restore the wxWizard wxEVT_WIZARD_FINISHED event, which was sent when the FINISHED button was pressed and the wizard was finished. When the wxWizard is modal this event is not needed. However, when the wizard is non-modal this is the only way to determine that the wizard has finished.

\section{\class{wxWizard}}\label{wxwizard}
|
|
|
|
wxWizard is the central class for implementing `wizard-like' dialogs. These
|
|
dialogs are mostly familiar to Windows users and are nothing else but a
|
|
sequence of `pages' each of them displayed inside a dialog which has the
|
|
buttons to pass to the next (and previous) pages.
|
|
|
|
The wizards are typically used to decompose a complex dialog into several
|
|
simple steps and are mainly useful to the novice users, hence it is important
|
|
to keep them as simple as possible.
|
|
|
|
To show a wizard dialog, you must first create an object of wxWizard class
|
|
using either the non default constructor or a default one followed by call to
|
|
\helpref{Create}{wxwizardcreate} function. Then you should add all pages you
|
|
want the wizard to show and call \helpref{RunWizard}{wxwizardrunwizard}.
|
|
Finally, don't forget to call {\tt wizard->Destroy()}.

\wxheading{Event table macros}
|
|
|
|
To process input from a wizard dialog, use these event handler macros to
|
|
direct input to member functions that take a
|
|
\helpref{wxWizardEvent}{wxwizardevent} argument. For some events,
|
|
\helpref{Veto()}{wxnotifyeventveto} can be called to prevent the event from
|
|
happening.

|
|
\twocolitem{{\bf EVT\_WIZARD\_PAGE\_CHANGED(id, func)}}{The page has been just
|
|
changed (this event can not be vetoed).}
|
|
\twocolitem{{\bf EVT\_WIZARD\_PAGE\_CHANGING(id, func)}}{The page is being
|
|
changed (this event can be vetoed).}
|
|
\twocolitem{{\bf EVT\_WIZARD\_CANCEL(id, func)}}{The user attempted to cancel
|
|
the wizard (this event may also be vetoed).}
|
|
\twocolitem{{\bf EVT\_WIZARD\_HELP(id, func)}}{The wizard help button was pressed.}
|
|
\twocolitem{{\bf EVT\_WIZARD\_FINISHED(id, func)}}{The wizard finished button was pressed.}
|
|
\end{twocollist}%
|
|
|
|
\wxheading{Extended styles}
|
|
|
|
Use the \helpref{wxWindow::SetExtraStyle}{wxwindowsetextrastyle} function to set the following
|
|
style. You will need to use two-step construction (use the default constructor, call {\bf SetExtraStyle}, then call {\bf Create}).
|

|
|
\begin{twocollist}\itemsep=0pt

See also \helpref{wxDialog}{wxdialog} for other extended styles.

\membersection{wxWizard::wxWizard}\label{wxwizardctor}
|
|
|
|
\func{}{wxWizard}{\void}
|
|
|
|
Default constructor. Use this if you wish to derive from wxWizard and then call
|
|
\helpref{Create}{wxwizardcreate}, for example if you wish to set an extra style
|
|
with \helpref{wxWindow::SetExtraStyle}{wxwindowsetextrastyle} between the two
|
|
calls.
|
|
|
|
\func{}{wxWizard}{\param{wxWindow* }{parent}, \param{int }{id = -1}, \param{const wxString\& }{title = wxEmptyString}, \param{const wxBitmap\& }{bitmap = wxNullBitmap}, \param{const wxPoint\& }{pos = wxDefaultPosition}}
|
|
|
|
Constructor which really creates the wizard -- if you use this constructor, you
|
|
shouldn't call \helpref{Create}{wxwizardcreate}.
|
|
|
|
Notice that unlike almost all other wxWindows classes, there is no {\it size}
|
|
parameter in wxWizard constructor because the wizard will have a predefined
|
|
default size by default. If you want to change this, you should use the
|
|
\helpref{SetPageSize}{wxwizardsetpagesize} function.
|
|
|
|
\wxheading{Parameters}
|
|
|
|
\docparam{parent}{The parent window, may be NULL.}
|
|
|
|
\docparam{id}{The id of the dialog, will usually be just $-1$.}
|
|
|
|
\docparam{title}{The title of the dialog.}
|
|
|
|
\docparam{bitmap}{The default bitmap used in the left side of the wizard. See
|
|
also \helpref{GetBitmap}{wxwizardpagegetbitmap}.}
|
|
|
|
\docparam{pos}{The position of the dialog, it will be centered on the screen
|
|
by default.}
|
|
|
|
\membersection{wxWizard::Create}\label{wxwizardcreate}
|
|
|
|
\func{bool}{Create}{\param{wxWindow* }{parent}, \param{int }{id = -1}, \param{const wxString\& }{title = wxEmptyString}, \param{const wxBitmap\& }{bitmap = wxNullBitmap}, \param{const wxPoint\& }{pos = wxDefaultPosition}}
|
|
|
|
Creates the wizard dialog. Must be called if the default constructor had been
|
|
used to create the object.
|
|
|
|
Notice that unlike almost all other wxWindows classes, there is no {\it size}
|
|
parameter in wxWizard constructor because the wizard will have a predefined
|
|
default size by default. If you want to change this, you should use the
|
|
\helpref{SetPageSize}{wxwizardsetpagesize} function.
|
|
|
|
\wxheading{Parameters}
|
|
|
|
\docparam{parent}{The parent window, may be NULL.}
|
|
|
|
\docparam{id}{The id of the dialog, will usually be just $-1$.}
|
|
|
|
\docparam{title}{The title of the dialog.}
|
|
|
|
\docparam{bitmap}{The default bitmap used in the left side of the wizard. See
|
|
also \helpref{GetBitmap}{wxwizardpagegetbitmap}.}
|
|
|
|
\docparam{pos}{The position of the dialog, it will be centered on the screen
|
|
by default.}
|
|
|
|
\membersection{wxWizard::FitToPage}\label{wxwizardfittopage}
|
|
|
|
\func{void}{FittoPage}{\param{const wxWizardPage* }{firstPage}}
|
|
|
|
Sets the page size to be big enough for all the pages accessible via the
|
|
given {\it firstPage}, i.e. this page, its next page and so on.
|
|
|
|
This method may be called more than once and it will only change the page size
|
|
if the size required by the new page is bigger than the previously set one.
|
|
This is useful if the decision about which pages to show is taken during the
|
|
run-time as in this case, the wizard won't be able to get to all pages starting
|
|
from a single one and you should call {\it Fit} separately for the others.
|
|
|
|
\membersection{wxWizard::GetCurrentPage}\label{wxwizardgetcurrentpage}
|
|
|
|
\constfunc{wxWizardPage*}{GetCurrentPage}{\void}
|
|
|
|
Get the current page while the wizard is running. {\tt NULL} is returned if
|
|
\helpref{RunWizard()}{wxwizardrunwizard} is not being executed now.
|
|
|
|
\membersection{wxWizard::GetPageSize}\label{wxwizardgetpagesize}
|
|
|
|
\constfunc{wxSize}{GetPageSize}{\void}
|
|
|
|
Returns the size available for the pages.
|
|
|
|
\membersection{wxWizard::HasNextPage}\label{wxwizardhasnextpage}
|
|
|
|
\func{virtual bool}{HasNextPage}{\param{wxWizardPage *}{page}}
|
|
|
|
Return {\tt TRUE} if this page is not the last one in the wizard. The base
|
|
class version implements this by calling
|
|
\helpref{page->GetNext}{wxwizardpagegetnext} but this could be undesirable if,
|
|
for example, the pages are created on demand only.
|
|
|
|
\wxheading{See also}
|
|
|
|
\helpref{HasPrevPage}{wxwizardhasprevpage}
|
|
|
|
\membersection{wxWizard::HasPrevPage}\label{wxwizardhasprevpage}
|
|
|
|
\func{virtual bool}{HasPrevPage}{\param{wxWizardPage *}{page}}
|
|
|
|
Return {\tt TRUE} if this page is not the last one in the wizard. The base
|
|
class version implements this by calling
|
|
\helpref{page->GetPrev}{wxwizardpagegetprev} but this could be undesirable if,
|
|
for example, the pages are created on demand only.
|
|
|
|
\wxheading{See also}
|
|
|
|
\helpref{HasNextPage}{wxwizardhasnextpage}
|
|
|
|
\membersection{wxWizard::RunWizard}\label{wxwizardrunwizard}
|
|
|
|
\func{bool}{RunWizard}{\param{wxWizardPage* }{firstPage}}
|
|
|
|
Executes the wizard starting from the given page, returns {\tt TRUE} if it was
|
|
successfully finished or {\tt FALSE} if user cancelled it. The {\it firstPage}
|
|
can not be {\tt NULL}.
|
|
|
|
\membersection{wxWizard::SetPageSize}\label{wxwizardsetpagesize}
|
|
|
|
\func{void}{SetPageSize}{\param{const wxSize\& }{sizePage}}
|
|
|
|
Sets the minimal size to be made available for the wizard pages. The wizard
|
|
will take into account the size of the bitmap (if any) itself. Also, the
|
|
wizard will never be smaller than the default size.
|
|
|
|
The recommended way to use this function is to layout all wizard pages using
|
|
the sizers (even though the wizard is not resizeable) and then use
|
|
\helpref{wxSizer::CalcMin}{wxsizercalcmin} in a loop to calculate the maximum
|
|
of minimal sizes of the pages and pass it to SetPageSize().
