These dialogs are mostly familiar to Windows users and are nothing other than a sequence of `pages', each displayed inside a dialog which has the buttons to navigate 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 instance of the wxWizard class using either the non-default constructor or a default one followed by call to the Create function. Then you should add all pages you want the wizard to show and call RunWizard . Finally, don't forget to call wizard->Destroy() . Extended styles Use the wxWindow::SetExtraStyle function to set the following style. You will need to use two-step construction (use the default constructor, call SetExtraStyle , then call Create ). wxWIZARD_EX_HELPBUTTON Shows a Help button using wxID_HELP. See also wxDialog for other extended styles. .SH "PARENTS" wxDialog wxPanel wxWindow wxEvtHandler wxObject .SH "INCLUDE FILES" wx/wizard.h .SH MEMBERS .SS wxWizard () Default constructor. Use this if you wish to derive from wxWizard and then call Create , for example if you wish to set an extra style with wxWindow::SetExtraStyle between the two calls. .SS wxWizard (wxWindow* parentint id = -1const wxString& title = wxEmptyStringconst wxBitmap& bitmap = wxNullBitmapconst wxPoint& pos = wxDefaultPositionlong style = wxDEFAULT_DIALOG_STYLE) Constructor which really creates the wizard -- if you use this constructor, you shouldn't call Create . Notice that unlike almost all other wxWidgets classes, there is no size parameter in the wxWizard constructor because the wizard will have a predefined default size by default. If you want to change this, you should use the GetPageAreaSizer function. .SS bool Create (wxWindow* parentint id = -1const wxString& title = wxEmptyStringconst wxBitmap& bitmap = wxNullBitmapconst wxPoint& pos = wxDefaultPositionlong style = wxDEFAULT_DIALOG_STYLE) Creates the wizard dialog. Must be called if the default constructor had been used to create the object. Notice that unlike almost all other wxWidgets classes, there is no size parameter in the wxWizard constructor because the wizard will have a predefined default size by default. If you want to change this, you should use the GetPageAreaSizer function. .SS void FitToPage (const wxWizardPage* firstPage) This method is obsolete, use GetPageAreaSizer instead. Sets the page size to be big enough for all the pages accessible via the given 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 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 Fit separately for the others. .SS wxWizardPage* GetCurrentPage () Get the current page while the wizard is running. NULL is returned if RunWizard() is not being executed now. .SS virtual wxSizer* GetPageAreaSizer () Returns pointer to page area sizer. The wizard is laid out using sizers and the page area sizer is the place-holder for the pages. All pages are resized before being shown to match the wizard page area. Page area sizer has a minimal size that is the maximum of several values. First, all pages (or other objects) added to the sizer. Second, all pages reachable by repeatedly applying wxWizardPage::GetNext to any page inserted into the sizer. Third, the minimal size specified using SetPageSize and FitToPage . Fourth, the total wizard height may be increased to accommodate the bitmap height. Fifth and finally, wizards are never smaller than some built-in minimal size to avoid wizards that are too small. The caller can use wxSizer::SetMinSize to enlarge it beyond the minimal size. If wxRESIZE_BORDER was passed to constructor, user can resize wizard and consequently the page area (but not make it smaller than the minimal size). It is recommended to add the first page to the page area sizer. For simple wizards, this will enlarge the wizard to fit the biggest page. For non-linear wizards, the first page of every separate chain should be added. Caller-specified size can be accomplished using wxSizer::SetMinSize . Adding pages to the page area sizer affects the default border width around page area that can be altered with SetBorder . .SS wxSize GetPageSize () Returns the size available for the pages. .SS virtual bool HasNextPage (wxWizardPage *page) Return true if this page is not the last one in the wizard. The base class version implements this by calling page->GetNext but this could be undesirable if, for example, the pages are created on demand only. .SS virtual bool HasPrevPage (wxWizardPage *page) Returns true if this page is not the last one in the wizard. The base class version implements this by calling page->GetPrev but this could be undesirable if, for example, the pages are created on demand only. .SS bool RunWizard (wxWizardPage* firstPage) Executes the wizard starting from the given page, returning true if it was successfully finished or false if user cancelled it. The firstPage can not be NULL . .SS void SetPageSize (const wxSize& sizePage) This method is obsolete, use GetPageAreaSizer instead. 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 lay out all wizard pages using the sizers (even though the wizard is not resizeable) and then use wxSizer::CalcMin in a loop to calculate the maximum of minimal sizes of the pages and pass it to SetPageSize(). .SS void SetBorder (int border) Sets width of border around page area. Default is zero. For backward compatibility, if there are no pages in GetPageAreaSizer , the default is 5 pixels. If there is a five point border around all controls in a page and the border around page area is left as zero, a five point white space along all dialog borders will be added to the control border in order to space page controls ten points from the dialog border and non-page controls. .SH EVENTS .SS EVT_WIZARD_PAGE_CHANGED(id, func) The page has just been changed (this event cannot be vetoed). .SS EVT_WIZARD_PAGE_CHANGING(id, func) The page is being changed (this event can be vetoed). .SS EVT_WIZARD_CANCEL(id, func) The user attempted to cancel the wizard (this event may also be vetoed). .SS EVT_WIZARD_HELP(id, func) The wizard help button was pressed. .SS EVT_WIZARD_FINISHED(id, func) The wizard finished button was pressed. .SH "SEE ALSO" wxDialog wxPanel wxWindow wxEvtHandler wxObject wxWizardEvent wxWizardPage wxWizard sample .SH "AUTHORS" Documentation content by Julian Smart, Robert Roebling, Vadim Zeitlin, Robin Dunn, et al Conversion to manpage format by Arnout Engelen (http://bzzt.net), bugreports welcome.
