\section{\class{wxGrid}}\label{wxgrid}

wxGrid and its related classes are used for displaying and editing tabular
data. They provide a rich set of features for display, editing, and
interacting with a variety of data sources. For simple applications, and to
help you get started, wxGrid is the only class you need to refer to
directly. It will set up default instances of the other classes and manage
them for you. For more complex applications you can derive your own
classes for custom grid views, grid data tables, cell editors and
renderers. The \helpref{wxGrid classes overview}{gridoverview} has
examples of simple and more complex applications, explains the
relationship between the various grid classes and has a summary of the
keyboard shortcuts and mouse functions provided by wxGrid.

wxGrid has been greatly expanded and redesigned for wxWidgets 2.2
onwards. If you have been using the old wxGrid class you will probably
want to have a look at the \helpref{wxGrid classes overview}{gridoverview} to see
how things have changed. The new grid classes are reasonably backward-compatible
but there are some exceptions. There are also easier ways of doing many things compared to
the previous implementation.

Increments the grid's batch count. When the count is greater than zero repainting of
the grid is suppressed. Each call to BeginBatch must be matched by a later call to
\helpref{wxGrid::EndBatch}{wxgridendbatch}. Code that does a lot of grid
modification can be enclosed between BeginBatch and EndBatch calls to avoid
screen flicker. The final EndBatch will cause the grid to be repainted.

\membersection{wxGrid::ClearGrid}\label{wxgridcleargrid}

\func{void}{ClearGrid}{\void}

Clears all data in the underlying grid table and repaints the grid. The table is not deleted by
this function. If you are using a derived table class then you need to override
\helpref{wxGridTableBase::Clear}{wxgridtablebaseclear} for this function to have any effect.



\membersection{wxGrid::ClearSelection}\label{wxgridclearselection}

\func{void}{ClearSelection}{\void}

Deselects all cells that are currently selected.

Creates a grid with the specified initial number of rows and columns.
Call this directly after the grid constructor. When you use this
function wxGrid will create and manage a simple table of string values
for you. All of the grid data will be stored in memory.

For applications with more complex data types or relationships, or for
dealing with very large datasets, you should derive your own grid table
class and pass a table object to the grid with \helpref{wxGrid::SetTable}{wxgridsettable}.

Deletes one or more columns from a grid starting at the specified position and returns
true if successful. The updateLabels argument is not used at present.

If you are using a derived grid table class you will need to override
\helpref{wxGridTableBase::DeleteCols}{wxgridtablebasedeletecols}. See
\helpref{wxGrid::InsertCols}{wxgridinsertcols} for further information.



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

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

Deletes one or more rows from a grid starting at the specified position and returns
true if successful. The updateLabels argument is not used at present.

If you are using a derived grid table class you will need to override
\helpref{wxGridTableBase::DeleteRows}{wxgridtablebasedeleterows}. See
\helpref{wxGrid::InsertRows}{wxgridinsertrows} for further information.

\func{void}{SetCellValue}{\param{const wxString\& }{val}, \param{int }{row}, \param{int }{col}}

Sets the string value for the cell at the specified location. For simple applications where a
grid object automatically uses a default grid table of string values you use this function together
with \helpref{wxGrid::GetCellValue}{wxgridgetcellvalue} to access cell values.

For more complex applications where you have derived your own grid table class that contains
various data types (e.g. numeric, boolean or user-defined custom types) then you only use this
function for those cells that contain string values.

The last form is for backward compatibility only.

See \helpref{wxGridTableBase::CanSetValueAs}{wxgridtablebasecangetvalueas}
and the \helpref{wxGrid overview}{gridoverview} for more information.

\membersection{wxGrid::SetColLabelSize}\label{wxgridsetcollabelsize}

\func{void}{SetColLabelSize}{\param{int }{height}}

Sets the height of the column labels.

If \arg{height} equals to \texttt{wxGRID\_AUTOSIZE} then height is calculated automatically
so that no label is truncated. Note that this could be slow for a large table.



\membersection{wxGrid::SetColLabelValue}\label{wxgridsetcollabelvalue}

\func{void}{SetColLabelValue}{\param{int }{col}, \param{const wxString\&}{ value}}

Set the value for the given column label. If you are using a derived grid table you must
override \helpref{wxGridTableBase::SetColLabelValue}{wxgridtablebasesetcollabelvalue}
for this to have any effect.



\membersection{wxGrid::SetColMinimalWidth}\label{wxgridsetcolminimalwidth}

\func{void}{SetColMinimalWidth}{\param{int }{col}, \param{int }{width}}

Sets the minimal width for the specified column. This should normally be called when creating the grid
because it will not resize a column that is already narrower than the minimal width.
The width argument must be higher than the minimimal acceptable column width, see
\helpref{wxGrid::GetColMinimalAcceptableWidth}{wxgridgetcolminimalacceptablewidth}.



\membersection{wxGrid::SetColMinimalAcceptableWidth}\label{wxgridsetcolminimalacceptablewidth}

\func{void}{SetColMinimalAcceptableWidth}{\param{int }{width}}

This modifies the minimum column width that can be handled correctly. Specifying a low value here
allows smaller grid cells to be dealt with correctly. Specifying a value here which is much smaller
than the actual minimum size will incur a performance penalty in the functions which perform
grid cell index lookup on the basis of screen coordinates.
This should normally be called when creating the grid because it will not resize existing columns
with sizes smaller than the value specified here.



\membersection{wxGrid::SetColPos}\label{wxgridsetcolpos}

\func{void}{SetColPos}{\param{int }{colID}, \param{int }{newPos}}

Sets the position of the specified column.



\membersection{wxGrid::SetColSize}\label{wxgridsetcolsize}

\func{void}{SetColSize}{\param{int }{col}, \param{int }{width}}

Sets the width of the specified column.

This function does not refresh the grid. If you are calling it outside of a BeginBatch / EndBatch
block you can use \helpref{wxGrid::ForceRefresh}{wxgridforcerefresh} to see the changes.

Automatically sizes the column to fit its contents. If setAsMin is true the calculated width will
also be set as the minimal width for the column.

\wxheading{Note}\\
wxGrid sets up arrays to store individual row and column sizes when non-default sizes are used.
The memory requirements for this could become prohibitive if your grid is very large.



\membersection{wxGrid::SetDefaultCellAlignment}\label{wxgridsetdefaultcellalignment}

\func{void}{SetDefaultCellAlignment}{\param{int }{horiz}, \param{int }{vert}}

Sets the default horizontal and vertical alignment for grid cell text.

Horizontal alignment should be one of wxALIGN\_LEFT, wxALIGN\_CENTRE or wxALIGN\_RIGHT.

A grid may occupy more space than needed for its rows/columns. This
function allows to set how big this extra space is



\membersection{wxGrid::SetOrCalcColumnSizes}\label{wxgridsetorcalccolumnsizes}

\func{int}{SetOrCalcColumnSizes}{\param{bool }{calcOnly}, \param{bool }{setAsMin = true}}

Common part of AutoSizeColumn/Row() and GetBestSize()



\membersection{wxGrid::SetOrCalcRowSizes}\label{wxgridsetorcalcrowsizes}

\func{int}{SetOrCalcRowSizes}{\param{bool }{calcOnly}, \param{bool }{setAsMin = true}}



\membersection{wxGrid::SetReadOnly}\label{wxgridsetreadonly}

\func{void}{SetReadOnly}{\param{int }{row}, \param{int }{col}, \param{bool }{isReadOnly = true}}

Makes the cell at the specified location read-only or editable.
See also \helpref{wxGrid::IsReadOnly}{wxgridisreadonly}.



\membersection{wxGrid::SetRowAttr}\label{wxgridsetrowattr}

\func{void}{SetRowAttr}{\param{int }{row}, \param{wxGridCellAttr* }{attr}}

Sets the cell attributes for all cells in the specified row.
See the \helpref{wxGridCellAttr}{wxgridcellattr} class for more information
about controlling cell attributes.



\membersection{wxGrid::SetRowLabelAlignment}\label{wxgridsetrowlabelalignment}

\func{void}{SetRowLabelAlignment}{\param{int }{horiz}, \param{int }{vert}}

Sets the horizontal and vertical alignment of row label text.

Horizontal alignment should be one of wxALIGN\_LEFT, wxALIGN\_CENTRE or wxALIGN\_RIGHT.

Vertical alignment should be one of wxALIGN\_TOP, wxALIGN\_CENTRE or wxALIGN\_BOTTOM.



\membersection{wxGrid::SetRowLabelSize}\label{wxgridsetrowlabelsize}

\func{void}{SetRowLabelSize}{\param{int }{width}}

Sets the width of the row labels.

If \arg{width} equals \texttt{wxGRID\_AUTOSIZE} then width is calculated automatically
so that no label is truncated. Note that this could be slow for a large table.



\membersection{wxGrid::SetRowLabelValue}\label{wxgridsetrowlabelvalue}

\func{void}{SetRowLabelValue}{\param{int }{row}, \param{const wxString\&}{ value}}

Set the value for the given row label. If you are using a derived grid table you must
override \helpref{wxGridTableBase::SetRowLabelValue}{wxgridtablebasesetrowlabelvalue}
for this to have any effect.



\membersection{wxGrid::SetRowMinimalHeight}\label{wxgridsetrowminimalheight}

\func{void}{SetRowMinimalHeight}{\param{int }{row}, \param{int }{height}}

Sets the minimal height for the specified row. This should normally be called when creating the grid
because it will not resize a row that is already shorter than the minimal height.
The height argument must be higher than the minimimal acceptable row height, see
\helpref{wxGrid::GetRowMinimalAcceptableHeight}{wxgridgetrowminimalacceptableheight}.



\membersection{wxGrid::SetRowMinimalAcceptableHeight}\label{wxgridsetrowminimalacceptableheight}

\func{void}{SetRowMinimalAcceptableHeight}{\param{int }{height}}

This modifies the minimum row width that can be handled correctly. Specifying a low value here
allows smaller grid cells to be dealt with correctly. Specifying a value here which is much smaller
than the actual minimum size will incur a performance penalty in the functions which perform
grid cell index lookup on the basis of screen coordinates.
This should normally be called when creating the grid because it will not resize existing rows
with sizes smaller than the value specified here.



\membersection{wxGrid::SetRowSize}\label{wxgridsetrowsize}

\func{void}{SetRowSize}{\param{int }{row}, \param{int }{height}}

Sets the height of the specified row.

This function does not refresh the grid. If you are calling it outside of a BeginBatch / EndBatch
block you can use \helpref{wxGrid::ForceRefresh}{wxgridforcerefresh} to see the changes.

Automatically sizes the column to fit its contents. If setAsMin is true the calculated width will
also be set as the minimal width for the column.

\wxheading{Note}

wxGrid sets up arrays to store individual row and column sizes when non-default sizes are used.
The memory requirements for this could become prohibitive if your grid is very large.



\membersection{wxGrid::SetScrollLineX}\label{wxgridsetscrolllinex}

\func{void}{SetScrollLineX}{\param{int }{x}}

Sets the number of pixels per horizontal scroll increment. The default is 15.
Sometimes wxGrid has trouble setting the scrollbars correctly due to rounding
errors: setting this to 1 can help.

\membersection{wxGrid::SetScrollLineY}\label{wxgridsetscrollliney}

\func{void}{SetScrollLineY}{\param{int }{y}}

Sets the number of pixels per vertical scroll increment. The default is 15.
Sometimes wxGrid has trouble setting the scrollbars correctly due to rounding
errors: setting this to 1 can help.

\membersection{wxGrid::SetSelectionBackground}\label{wxgridsetselectionbackground}

\func{void}{SetSelectionBackground}{\param{const wxColour\& }{c}}



\membersection{wxGrid::SetSelectionForeground}\label{wxgridsetselectionforeground}

\func{void}{SetSelectionForeground}{\param{const wxColour\& }{c}}



\membersection{wxGrid::SetSelectionMode}\label{wxgridsetselectionmode}

\func{void}{SetSelectionMode}{\param{wxGrid::wxGridSelectionModes}{ selmode}}

Set the selection behaviour of the grid.

\wxheading{Parameters}

\docparam{wxGrid::wxGridSelectCells}{The default mode where individual cells are selected.}

\docparam{wxGrid::wxGridSelectRows}{Selections will consist of whole rows.}

\docparam{wxGrid::wxGridSelectColumns}{Selections will consist of whole columns.}



\membersection{wxGrid::SetTable}\label{wxgridsettable}

\func{bool}{SetTable}{\param{wxGridTableBase* }{table}, \param{bool }{takeOwnership = false}, \param{wxGrid::wxGridSelectionModes }{selmode = wxGrid::wxGridSelectCells}}

Passes a pointer to a custom grid table to be used by the grid. This should be called
after the grid constructor and before using the grid object. If takeOwnership is set to
true then the table will be deleted by the wxGrid destructor.

Use this function instead of \helpref{wxGrid::CreateGrid}{wxgridcreategrid} when your
application involves complex or non-string data or data sets that are too large to fit
wholly in memory.



\membersection{wxGrid::ShowCellEditControl}\label{wxgridshowcelleditcontrol}

\func{void}{ShowCellEditControl}{\void}

Displays the in-place cell edit control for the current cell.



\membersection{wxGrid::XToCol}\label{wxgridxtocol}

\constfunc{int}{XToCol}{\param{int }{x}, \param{bool }{clipToMinMax = false}}

\wxheading{Parameters}
\docparam{x}{The x position to evaluate.}
\docparam{clipToMinMax}{If true, rather than returning wxNOT\_FOUND, it returns either the first or last column depending on whether x is too far to the left or right respectively.}

\wxheading{Return value}
The grid column that corresponds to the logical x coordinate. Returns
{\tt wxNOT\_FOUND} if there is no column at the x position.



\membersection{wxGrid::XToEdgeOfCol}\label{wxgridxtoedgeofcol}

\constfunc{int}{XToEdgeOfCol}{\param{int }{x}}

Returns the column whose right hand edge is close to the given logical x position.
If no column edge is near to this position {\tt wxNOT\_FOUND} is returned.



\membersection{wxGrid::YToEdgeOfRow}\label{wxgridytoedgeofrow}

\constfunc{int}{YToEdgeOfRow}{\param{int }{y}}

Returns the row whose bottom edge is close to the given logical y position.
If no row edge is near to this position {\tt wxNOT\_FOUND} is returned.



\membersection{wxGrid::YToRow}\label{wxgridytorow}

\constfunc{int}{YToRow}{\param{int }{y}}

Returns the grid row that corresponds to the logical y coordinate. Returns
{\tt wxNOT\_FOUND} if there is no row at the y position.
