}}\label{wxgrid
}
14 wxGrid and its related classes are used for displaying and editing tabular
15 data. They provide a rich set of features for display, editing, and
16 interacting with a variety of data sources. For simple applications, and to
17 help you get started, wxGrid is the only class you need to refer to
18 directly. It will set up default instances of the other classes and manage
19 them for you. For more complex applications you can derive your own
20 classes for custom grid views, grid data tables, cell editors and
21 renderers. The
\helpref{wxGrid classes overview
}{gridoverview
} has
22 examples of simple and more complex applications, explains the
23 relationship between the various grid classes and has a summary of the
24 keyboard shortcuts and mouse functions provided by wxGrid.
26 wxGrid has been greatly expanded and redesigned for wxWidgets
2.2
27 onwards. If you have been using the old wxGrid class you will probably
28 want to have a look at the
\helpref{wxGrid classes overview
}{gridoverview
} to see
29 how things have changed. The new grid classes are reasonably backward-compatible
30 but there are some exceptions. There are also easier ways of doing many things compared to
31 the previous implementation.

178 Automatically sets the height and width of all rows and columns to fit their contents.
181 wxGrid sets up arrays to store individual row and column sizes when non-default sizes are used.

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

272 Returns true if columns can be resized by dragging with the mouse. Columns can be resized
273 by dragging the edges of their labels. If grid line dragging is enabled they can also be

283 Returns true if rows can be resized by dragging with the mouse. Rows can be resized
284 by dragging the edges of their labels. If grid line dragging is enabled they can also be
285 resized by dragging the lower edge of the row in the grid cell area
286 (see
\helpref{wxGrid::EnableDragGridSize
}{wxgridenabledraggridsize
}).
290 \membersection{wxGrid::CanDragGridSize

300 \constfunc{bool

330 Clears all data in the underlying grid table and repaints the grid. The table is not deleted by
331 this function. If you are using a derived table class then you need to override
332 \helpref{wxGridTableBase::Clear

348 Creates a grid with the specified initial number of rows and columns.
349 Call this directly after the grid constructor. When you use this
350 function wxGrid will create and manage a simple table of string values
351 for you. All of the grid data will be stored in memory.
353 For applications with more complex data types or relationships, or for
354 dealing with very large datasets, you should derive your own grid table
355 class and pass a table object to the grid with
\helpref{wxGrid::SetTable
}{wxgridsettable

363 Deletes one or more columns from a grid starting at the specified position and returns
364 true if successful. The updateLabels argument is not used at present.
366 If you are using a derived grid table class you will need to override

}{wxgridtablebasedeletecols

376 Deletes one or more rows from a grid starting at the specified position and returns
377 true if successful. The updateLabels argument is not used at present.
379 If you are using a derived grid table class you will need to override
380 \helpref{wxGridTableBase::DeleteRows
}{wxgridtablebasedeleterows

\_GRID\_EDITOR\_SHOWN or wxEVT
\_GRID\_EDITOR\_HIDDEN event.

456 \func{void
}{EnableEditing
}{\param{bool
}{edit
}}
458 If the edit argument is false this function sets the whole grid as read-only. If the
459 argument is true the grid is set to the default state where cells may be editable. In the
460 default state you can set single grid cells and whole rows and columns to be editable or
462 \helpref{wxGridCellAttribute::SetReadOnly
}{wxgridcellattrsetreadonly
}. For single
463 cells you can also use the shortcut function
464 \helpref{wxGrid::SetReadOnly
}{wxgridsetreadonly
}.

467 \helpref{wxGridCellAttr

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

511 \func{int
}{GetBatchCount

513 Returns the number of times that
\helpref{wxGrid::BeginBatch

514 without (yet) matching calls to
\helpref{wxGrid::EndBatch

524 grid cell at the specified location.
526 Horizontal alignment will be one of wxALIGN
\_LEFT, wxALIGN

527 Vertical alignment will be one of wxALIGN
\_TOP, wxALIGN
\_CENTRE or wxALIGN

586 Returns the string contained in the cell at the specified location. For simple applications where a
587 grid object automatically uses a default grid table of string values you use this function together
588 with

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

1431 Sets the string value for the cell at the specified location. For simple applications where a
1432 grid object automatically uses a default grid table of string values you use this function together
1433 with
\helpref{wxGrid::GetCellValue

1435 For more complex applications where you have derived your own grid table class that contains
1436 various data types (e.g. numeric, boolean or user-defined custom types) then you only use this
1437 function for those cells that contain string values.

1526 Sets the minimal width for the specified column. This should normally be called when creating the grid
1527 because it will not resize a column that is already narrower than the minimal width.
1528 The width argument must be higher than the minimimal acceptable column width, see

1537 This modifies the minimum column width that can be handled correctly. Specifying a low value here
1538 allows smaller grid cells to be dealt with correctly. Specifying a value here which is much smaller
1539 than the actual minimum size will incur a performance penalty in the functions which perform
1540 grid cell index lookup on the basis of screen coordinates.
1541 This should normally be called when creating the grid because it will not resize existing columns

1555 Automatically sizes the column to fit its contents. If setAsMin is true the calculated width will
1556 also be set as the minimal width for the column.
1559 wxGrid sets up arrays to store individual row and column sizes when non-default sizes are used.
