There are no specific window styles for this class, but you may use different
SetXXX() functions to change the controls behaviour (for example, to enable
in-place editing).

\membersection{wxGrid::wxGrid}\label{wxgridconstr}

\func{void}{wxGrid}{\param{wxWindow* }{parent}, \param{wxWindowID}{ id}, \param{const wxPoint\&}{ pos},
\rtfsp\param{const wxSize\&}{ size}, \param{long}{ style=0}, \param{const wxString\& }{name="grid"}}

Constructor. Before using a wxGrid object, you must call CreateGrid to set up the required rows and columns.

\membersection{wxGrid::AdjustScrollbars}\label{wxgridadjustscrollbars}

\func{void}{AdjustScrollbars}{\void}

Call this function whenever a change has been made via the API that might alter the scrollbar characteristics:
particularly when adding or deleting rows, or changing row or column dimensions. For example,
removing rows might make it unnecessary to show the vertical scrollbar.

\membersection{wxGrid::AppendCols}\label{wxgridappendcols}

\func{bool}{AppendCols}{\param{int}{ n=1}, \param{bool}{ updateLabels=TRUE}}

Appends {\it n} columns to the grid. If {\it updateLabels} is TRUE,
the function OnChangeLabels is called to give the application the opportunity to relabel.

\membersection{wxGrid::AppendRows}\label{wxgridappendrows}

\func{bool}{AppendRows}{\param{int}{ n=1}, \param{bool}{ updateLabels=TRUE}}

Appends {\it n} rows to the grid. If {\it updateLabels} is TRUE,
the function OnChangeLabels is called to give the application the opportunity to relabel.

\membersection{wxGrid::BeginBatch}\label{wxgridbeginbatch}

\func{void}{BeginBatch}{\void}

Start a BeginBatch/EndBatch pair between which, calls to SetCellValue or
SetCellBitmap will not cause a refresh. This allows you to speed up some operations
(for example, setting several hundred cell values). You can nest, but not overlap,
these two functions.

See also \helpref{wxGrid::EndBatch}{wxgridendbatch}, \helpref{wxGrid::GetBatchCount}{wxgridgetbatchcount}.

\membersection{wxGrid::CellHitTest}\label{wxgridcellhittest}

\func{bool}{CellHitTest}{\param{int}{ x}, \param{int}{ y}, \param{int *}{row}, \param{int *}{col}}

Returns TRUE if the x, y panel position coincides with a cell. If so, {\it row} and {\it col} are
returned.

\membersection{wxGrid::CreateGrid}\label{wxgridcreategrid}

\func{bool}{CreateGrid}{\param{int}{ rows}, \param{int}{ cols}, \param{wxString **}{cellValues=NULL},
 \param{short *}{widths=NULL}, \param{short}{ defaultWidth=wxGRID\_DEFAULT\_CELL\_WIDTH},
 \param{short}{ defaultHeight=wxGRID\_DEFAULT\_CELL\_HEIGHT}}

Creates a grid {\it rows} high and {\it cols} wide. You can optionally specify an array of initial values
and widths, and/or default cell width and height.

Call this function after creating the wxGrid object.

\pythonnote{Currently the \tt{cellValues} and \tt{widths} parameters
don't exisit in the wxPython version of this method.  So in other
words, the definition of the  wxPython version of this method looks like this:
\begin{verbatim}
    CreateGrid(rows, cols,
               defaultWidth = wxGRID_DEFAULT_CELL_WIDTH,
               defaultHeight = wxGRID_DEFAULT_CELL_HEIGHT)
\end{verbatim}
}

\membersection{wxGrid::CurrentCellVisible}\label{wxgridcurrentcellvisible}

\func{bool}{CurrentCellVisible}{\void}

Returns TRUE if the currently selected cell is visible, FALSE otherwise.

\membersection{wxGrid::DeleteCols}\label{wxgriddeletecols}

\func{bool}{DeleteCols}{\param{int}{ pos=0}, \param{int}{ n=1}, \param{bool}{ updateLabels=TRUE}}

Deletes {\it n} columns from the grid at position {\it pos}. If {\it updateLabels} is TRUE,
the function OnChangeLabels is called to give the application the opportunity to relabel.

\membersection{wxGrid::DeleteRows}\label{wxgriddeleterows}

\func{bool}{DeleteRows}{\param{int}{ pos=0}, \param{int}{ n=1}, \param{bool}{ updateLabels=TRUE}}

Deletes {\it n} rows from the grid at position {\it pos}. If {\it updateLabels} is TRUE,
the function OnChangeLabels is called to give the application the opportunity to relabel.

\membersection{wxGrid::EndBatch}\label{wxgridendbatch}

\func{void}{EndBatch}{\void}

End a BeginBatch/EndBatch pair between which, calls to SetCellValue or
SetCellBitmap will not cause a refresh. This allows you to speed up some operations
(for example, setting several hundred cell values). You can nest, but not overlap,
these two functions.

See also \helpref{wxGrid::BeginBatch}{wxgridbeginbatch}, \helpref{wxGrid::GetBatchCount}{wxgridgetbatchcount}.

\membersection{wxGrid::GetBatchCount}\label{wxgridgetbatchcount}

\constfunc{int}{GetBatchCount}{\void}

Return the level of batch nesting. This is initially zero, and will be incremented
every time BeginBatch is called, and decremented when EndBatch is called. When the
batch count is more zero, some functions (such as SetCellValue and SetCellBitmap) will
not refresh the cell.

See also \helpref{wxGrid::BeginBatch}{wxgridbeginbatch}, \helpref{wxGrid::EndBatch}{wxgridendbatch}.
