\membersection{wxTabView::wxTabView}

\func{}{wxTabView}{\param{long }{style = wxTAB\_STYLE\_DRAW\_BOX \pipe wxTAB\_STYLE\_COLOUR\_INTERIOR}}

Constructor.

{\it style} may be a bit list of the following:

\begin{twocollist}\itemsep=0pt
\twocolitem{wxTAB\_STYLE\_DRAW\_BOX}{Draw a box around the view area. Most commonly used for dialogs.}
\twocolitem{wxTAB\_STYLE\_COLOUR\_INTERIOR}{Draw tab backgrounds in the specified colour. Omitting this style
will ensure that the tab background matches the dialog background.}
\end{twocollist}

\membersection{wxTabView::AddTab}\label{wxtabviewaddtab}

\func{wxTabControl *}{AddTab}{\param{int}{ id}, \param{const wxString\& }{label}, \param{wxTabControl *}{existingTab=NULL}}

Adds a tab to the view.

{\it id} is the application-chosen identifier for the tab, which will be used in subsequent tab operations.

{\it label} is the label to give the tab.

{\it existingTab} maybe NULL to specify a new tab, or non-NULL to indicate that an existing tab should be used.

A new layer (row) is started when the current layer has been filled up with tabs.

\membersection{wxTabView::CalculateTabWidth}\label{wxtabviewcalculatetabwidth}

\func{int}{CalculateTabWidth}{\param{int}{ noTabs}, \param{bool}{ adjustView = false}}

The application can specify the tab width using this function, in terms
of the number of tabs per layer (row) which will fit the view area, which
should have been set previously with SetViewRect.

{\it noTabs} is the number of tabs which should take up the full width
of the view area.

{\it adjustView} can be set to true in order to readjust the view width
to exactly fit the given number of tabs. 

The new tab width is returned.

\membersection{wxTabView::ClearTabs}

\func{void}{ClearTabs}{\param{bool }{deleteTabs=true}}

Clears the tabs, deleting them if {\it deleteTabs} is true.

\membersection{wxTabView::Draw}

\func{void}{Draw}{\param{wxDC\& }{dc}}

Draws the tabs and (optionally) a box around the view area.

\membersection{wxTabView::FindTabControlForId}

\func{wxTabControl *}{FindTabControlForId}{\param{int}{ id}}

Finds the wxTabControl corresponding to {\it id}.

\membersection{wxTabView::FindTabControlForPosition}

\func{wxTabControl *}{FindTabControlForPosition}{\param{int}{ layer}, \param{int}{ position}}

Finds the wxTabControl at layer {\it layer}, position in layer {\it position}, both starting from
zero. Note that tabs change layer as they are selected or deselected.

the wxTAB\_STYLE\_COLOUR\_INTERIOR flag from the wxTabView constructor. 

\membersection{wxTabView::GetBackgroundPen}

\membersection{wxTabView::OnCreateTabControl}

\func{wxTabControl *}{OnCreateTabControl}{\void}

to define a derived class, in which case the tab view should be subclassed and this function overridden.

\membersection{wxTabView::LayoutTabs}

\func{void}{LayoutTabs}{\void}
