\func{void}{InitColWidths}{\void}

Init the m\_colWidths/Rights arrays



\membersection{wxGrid::InitRowHeights}\label{wxgridinitrowheights}

\func{void}{InitRowHeights}{\void}

NB: {\it never} access m\_row/col arrays directly because they are created
on demand, {\it always} use accessor functions instead!

\membersection{wxGrid::InsertCols}\label{wxgridinsertcols}

\func{bool}{InsertCols}{\param{int }{pos = 0}, \param{int }{numCols = 1}, \param{bool }{updateLabels = true}}

Inserts one or more new columns into a grid with the first new column at the
specified position and returns true if successful. The updateLabels argument is not
used at present.

The sequence of actions begins with the grid object requesting the underlying grid
table to insert new columns. If this is successful the table notifies the grid and the
grid updates the display. For a default grid (one where you have called
\helpref{wxGrid::CreateGrid}{wxgridcreategrid}) this process is automatic. If you are
using a custom grid table (specified with \helpref{wxGrid::SetTable}{wxgridsettable})
then you must override
\helpref{wxGridTableBase::InsertCols}{wxgridtablebaseinsertcols} in your derived
table class.



\membersection{wxGrid::InsertRows}\label{wxgridinsertrows}

\func{bool}{InsertRows}{\param{int }{pos = 0}, \param{int }{numRows = 1}, \param{bool }{updateLabels = true}}

Inserts one or more new rows into a grid with the first new row at the specified
position and returns true if successful. The updateLabels argument is not used at
present.

The sequence of actions begins with the grid object requesting the underlying grid
table to insert new rows. If this is successful the table notifies the grid and the
grid updates the display. For a default grid (one where you have called
\helpref{wxGrid::CreateGrid}{wxgridcreategrid}) this process is automatic. If you are
using a custom grid table (specified with \helpref{wxGrid::SetTable}{wxgridsettable})
then you must override
\helpref{wxGridTableBase::InsertRows}{wxgridtablebaseinsertrows} in your derived
table class.



\membersection{wxGrid::IsCellEditControlEnabled}\label{wxgridiscelleditcontrolenabled}

\constfunc{bool}{IsCellEditControlEnabled}{\void}

Returns true if the in-place edit control is currently enabled.



\membersection{wxGrid::IsCurrentCellReadOnly}\label{wxgridiscurrentcellreadonly}

\constfunc{bool}{IsCurrentCellReadOnly}{\void}

Returns true if the current cell has been set to read-only
(see \helpref{wxGrid::SetReadOnly}{wxgridsetreadonly}).



\membersection{wxGrid::IsEditable}\label{wxgridiseditable}

\func{bool}{IsEditable}{\void}

Returns false if the whole grid has been set as read-only or true otherwise.
See \helpref{wxGrid::EnableEditing}{wxgridenableediting} for more information about
controlling the editing status of grid cells.
