\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.
|
|
|
|
\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.
|
|
|
|
