\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.

\begin{twocollist}\itemsep=2pt
|
|
\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}).
|
|
|
|
\twocolwidtha{5cm}%
|
|
\begin{twocollist}\itemsep=0pt
|
|
\twocolitem{\windowstyle{wxWIZARD\_EX\_HELPBUTTON}}{Shows a Help button using wxID\_HELP.}
|
|
\end{twocollist}
|
|
|
|
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().
