1096 Class providing attributes to be used for the grid cells.
1097
1098 This class both defines an interface which grid cell attributes providers
1099 should implement -- and which can be implemented differently in derived
1100 classes -- and a default implementation of this interface which is often
1101 good enough to be used without modification, especially with not very large
1102 grids for which the efficiency of attributes storage hardly matters (see
1103 the discussion below).
1104
1105 An object of this class can be associated with a wxGrid using
1106 wxGridTableBase::SetAttrProvider() but it's not necessary to call it if you
1107 intend to use the default provider as it is used by wxGridTableBase by
1108 default anyhow.
1109
1110 Notice that while attributes provided by this class can be set for
1111 individual cells using SetAttr() or the entire rows or columns using
1112 SetRowAttr() and SetColAttr() they are always retrieved using GetAttr()
1113 function.
1114
1115
1116 The default implementation of this class stores the attributes passed to
1117 its SetAttr(), SetRowAttr() and SetColAttr() in a straightforward way. A
1118 derived class may use its knowledge about how the attributes are used in
1119 your program to implement it much more efficiently: for example, using a
1120 special background colour for all even-numbered rows can be implemented by
1121 simply returning the same attribute from GetAttr() if the row number is
1122 even instead of having to store N/2 row attributes where N is the total
1123 number of rows in the grid.

1906 @class wxGrid
1907
1908 wxGrid and its related classes are used for displaying and editing tabular
1909 data. They provide a rich set of features for display, editing, and
1910 interacting with a variety of data sources. For simple applications, and to
1911 help you get started, wxGrid is the only class you need to refer to
1912 directly. It will set up default instances of the other classes and manage
1913 them for you. For more complex applications you can derive your own classes
1914 for custom grid views, grid data tables, cell editors and renderers. The
1915 @ref overview_grid has examples of simple and more complex applications,
1916 explains the relationship between the various grid classes and has a
1917 summary of the keyboard shortcuts and mouse functions provided by wxGrid.
1918
1919 A wxGridTableBase class holds the actual data to be displayed by a wxGrid
1920 class. One or more wxGrid classes may act as a view for one table class.
1921 The default table class is called wxGridStringTable and holds an array of
1922 strings. An instance of such a class is created by CreateGrid().
1923
1924 wxGridCellRenderer is the abstract base class for rendering contents in a
1925 cell. The following renderers are predefined:
1926
1927 - wxGridCellBoolRenderer
1928 - wxGridCellFloatRenderer
1929 - wxGridCellNumberRenderer
1930 - wxGridCellStringRenderer
1931
1932 The look of a cell can be further defined using wxGridCellAttr. An object
1933 of this type may be returned by wxGridTableBase::GetAttr().
1934
1935 wxGridCellEditor is the abstract base class for editing the value of a
1936 cell. The following editors are predefined:
1937
1938 - wxGridCellBoolEditor
1939 - wxGridCellChoiceEditor
1940 - wxGridCellFloatEditor
1941 - wxGridCellNumberEditor
1942 - wxGridCellTextEditor
1943
1944 Please see wxGridEvent, wxGridSizeEvent, wxGridRangeSelectEvent, and
1945 wxGridEditorCreatedEvent for the documentation of all event types you can

2344 code itself. This has the advantage of making the grid look and feel
2345 perfectly the same as native applications (using SetUseNativeColLabels()
2346 the grid can be made to look more natively but it still doesn't feel
2347 natively, notably the column resizing and dragging still works slightly
2348 differently as it is implemented in wxWidgets itself) but results in
2349 different behaviour for column and row headers, for which there is no
2350 equivalent function, and, most importantly, is unsuitable for grids
2351 with huge numbers of columns as wxHeaderCtrl doesn't support virtual
2352 mode. Because of this, by default the grid does not use the native
2353 header control but you should call this function to enable it if you
2354 are using the grid to display tabular data and don't have thousands of
2355 columns in it.
2356
2357 Another difference between the default behaviour and the native header
2358 behaviour is that the latter provides the user with a context menu
2359 (which appears on right clicking the header) allowing to rearrange the
2360 grid columns if CanDragColMove() returns @true. If you want to prevent
2361 this from happening for some reason, you need to define a handler for
2362 @c wxEVT_GRID_LABEL_RIGHT_CLICK event which simply does nothing (in
2363 particular doesn't skip the event) as this will prevent the default
2364 right click handling from working.
2365
2366 Also note that currently @c wxEVT_GRID_LABEL_RIGHT_DCLICK event is not
2367 generated for the column labels if the native columns header is used

2723 @c wxGRID_VALUE_STRING which uses wxGridCellStringRenderer and

4489
4490 This small class can be used to prevent wxGrid from redrawing during its
4491 lifetime by calling wxGrid::BeginBatch() in its constructor and
4492 wxGrid::EndBatch() in its destructor. It is typically used in a function
4493 performing several operations with a grid which would otherwise result in
4494 flicker. For example:
4495
4496 @code
4497 void MyFrame::Foo()
4498 {
4499 m_grid = new wxGrid(this, ...);
4500
4501 wxGridUpdateLocker noUpdates(m_grid);
4502 m_grid-AppendColumn();
4503 // ... many other operations with m_grid ...
4504 m_grid-AppendRow();
4505
4506 // destructor called, grid refreshed
4507 }
4508 @endcode
4509
4510 Using this class is easier and safer than calling wxGrid::BeginBatch() and
4511 wxGrid::EndBatch() because you don't risk missing the call the latter (due
4512 to an exception for example).

4548
4549 This event class contains information about various grid events.
4550
4551 Notice that all grid event table macros are available in two versions:
4552 @c EVT_GRID_XXX and @c EVT_GRID_CMD_XXX. The only difference between the
4553 two is that the former doesn't allow to specify the grid window identifier
4554 and so takes a single parameter, the event handler, but is not suitable if
4555 there is more than one grid control in the window where the event table is
4556 used (as it would catch the events from all the grids). The version with @c
4557 CMD takes the id as first argument and the event handler as the second one
4558 and so can be used with multiple grids as well. Otherwise there are no
4559 difference between the two and only the versions without the id are
4560 documented below for brevity.
4561
4562 @beginEventTable{wxGridEvent}
4563 @event{EVT_GRID_CELL_CHANGING(func)}
4564 The user is about to change the data in a cell. The new cell value as
4565 string is available from GetString() event object method. This event
4566 can be vetoed if the change is not allowed.
4567 Processes a @c wxEVT_GRID_CELL_CHANGING event type.
4568 @event{EVT_GRID_CELL_CHANGED(func)}
4569 The user changed the data in a cell. The old cell value as string is
4570 available from GetString() event object method. Notice that vetoing
4571 this event still works for backwards compatibility reasons but any new
4572 code should only veto EVT_GRID_CELL_CHANGING event and not this one.
4573 Processes a @c wxEVT_GRID_CELL_CHANGED event type.
4574 @event{EVT_GRID_CELL_LEFT_CLICK(func)}
4575 The user clicked a cell with the left mouse button. Processes a
4576 @c wxEVT_GRID_CELL_LEFT_CLICK event type.
4577 @event{EVT_GRID_CELL_LEFT_DCLICK(func)}
4578 The user double-clicked a cell with the left mouse button. Processes a
4579 @c wxEVT_GRID_CELL_LEFT_DCLICK event type.
4580 @event{EVT_GRID_CELL_RIGHT_CLICK(func)}
4581 The user clicked a cell with the right mouse button. Processes a
4582 @c wxEVT_GRID_CELL_RIGHT_CLICK event type.
4583 @event{EVT_GRID_CELL_RIGHT_DCLICK(func)}
4584 The user double-clicked a cell with the right mouse button. Processes a
4585 @c wxEVT_GRID_CELL_RIGHT_DCLICK event type.
4586 @event{EVT_GRID_EDITOR_HIDDEN(func)}
4587 The editor for a cell was hidden. Processes a
4588 @c wxEVT_GRID_EDITOR_HIDDEN event type.
4589 @event{EVT_GRID_EDITOR_SHOWN(func)}
4590 The editor for a cell was shown. Processes a
4591 @c wxEVT_GRID_EDITOR_SHOWN event type.
4592 @event{EVT_GRID_LABEL_LEFT_CLICK(func)}
4593 The user clicked a label with the left mouse button. Processes a
4594 @c wxEVT_GRID_LABEL_LEFT_CLICK event type.
4595 @event{EVT_GRID_LABEL_LEFT_DCLICK(func)}
4596 The user double-clicked a label with the left mouse button. Processes a
4597 @c wxEVT_GRID_LABEL_LEFT_DCLICK event type.
4598 @event{EVT_GRID_LABEL_RIGHT_CLICK(func)}
4599 The user clicked a label with the right mouse button. Processes a
4600 @c wxEVT_GRID_LABEL_RIGHT_CLICK event type.
4601 @event{EVT_GRID_LABEL_RIGHT_DCLICK(func)}
4602 The user double-clicked a label with the right mouse button. Processes
4603 a @c wxEVT_GRID_LABEL_RIGHT_DCLICK event type.
4604 @event{EVT_GRID_SELECT_CELL(func)}
4605 The given cell was made current, either by user or by the program via a
4606 call to SetGridCursor() or GoToCell(). Processes a
4607 @c wxEVT_GRID_SELECT_CELL event type.
4608 @event{EVT_GRID_COL_MOVE(func)}
4609 The user tries to change the order of the columns in the grid by
4610 dragging the column specified by GetCol(). This event can be vetoed to
4611 either prevent the user from reordering the column change completely
4612 (but notice that if you don't want to allow it at all, you simply
4613 shouldn't call wxGrid::EnableDragColMove() in the first place), vetoed
4614 but handled in some way in the handler, e.g. by really moving the
4615 column to the new position at the associated table level, or allowed to
4616 proceed in which case wxGrid::SetColPos() is used to reorder the
4617 columns display order without affecting the use of the column indices
4618 otherwise.
4619 This event macro corresponds to @c wxEVT_GRID_COL_MOVE event type.
4620 @event{EVT_GRID_COL_SORT(func)}
4621 This event is generated when a column is clicked by the user and its
4622 name is explained by the fact that the custom reaction to a click on a
4623 column is to sort the grid contents by this column. However the grid
4624 itself has no special support for sorting and it's up to the handler of
4625 this event to update the associated table. But if the event is handled
4626 (and not vetoed) the grid supposes that the table was indeed resorted
4627 and updates the column to indicate the new sort order and refreshes
4628 itself.
4629 This event macro corresponds to @c wxEVT_GRID_COL_SORT event type.
4630 @event{EVT_GRID_TABBING(func)}
4631 This event is generated when the user presses TAB or Shift-TAB in the
4632 grid. It can be used to customize the simple default TAB handling
4633 logic, e.g. to go to the next non-empty cell instead of just the next
4634 cell. See also wxGrid::SetTabBehaviour(). This event is new since
4635 wxWidgets 2.9.5.
