- @page overview_grid wxGrid Overview
- @tableofcontents
- wxGrid and its related classes are used for displaying and editing tabular
- data. wxGrid supports custom attributes for the table cells, allowing to
- completely customize its appearance and uses a separate grid table
- (wxGridTableBase-derived) class for the data management meaning that it can be
- used to display arbitrary amounts of data.
- @section overview_grid_simpleexample Getting Started
- For simple applications you need only refer to the wxGrid class in your code.
- This example shows how you might create a grid in a frame or dialog constructor
- and illustrates some of the formatting functions.
- @code
- // Create a wxGrid object
- grid = new wxGrid( this,
- -1,
- wxPoint( 0, 0 ),
- wxSize( 400, 300 ) );
- // Then we call CreateGrid to set the dimensions of the grid
- // (100 rows and 10 columns in this example)
- grid->CreateGrid( 100, 10 );
- // We can set the sizes of individual rows and columns
- // in pixels
- grid->SetRowSize( 0, 60 );
- grid->SetColSize( 0, 120 );
- // And set grid cell contents as strings
- grid->SetCellValue( 0, 0, "wxGrid is good" );
- // We can specify that some cells are read->only
- grid->SetCellValue( 0, 3, "This is read->only" );
- grid->SetReadOnly( 0, 3 );
- // Colours can be specified for grid cell contents
- grid->SetCellValue(3, 3, "green on grey");
- grid->SetCellTextColour(3, 3, *wxGREEN);
- grid->SetCellBackgroundColour(3, 3, *wxLIGHT_GREY);
- // We can specify the some cells will store numeric
- // values rather than strings. Here we set grid column 5
- // to hold floating point values displayed with width of 6
- // and precision of 2
- grid->SetColFormatFloat(5, 6, 2);
- grid->SetCellValue(0, 6, "3.1415");
- @endcode
- Here is a list of classes related to wxGrid:
- @li wxGrid: The main grid control class itself.
- @li wxGridTableBase: The base class for grid data provider.
- @li wxGridStringTable: Simple wxGridTableBase implementation supporting only
- string data items and storing them all in memory (hence suitable for not
- too large grids only).
- @li wxGridCellAttr: A cell attribute, allowing to customize its appearance as
- well as the renderer and editor used for displaying and editing it.
- @li wxGridCellAttrProvider: The object responsible for storing and retrieving
- the cell attributes.
- @li wxGridColLabelWindow: The window showing the grid columns labels.
- @li wxGridRowLabelWindow: The window showing the grid rows labels.
- @li wxGridCornerLabelWindow: The window used in the upper left grid corner.
- @li wxGridWindow: The window representing the main part of the grid.
- @li wxGridCellRenderer: Base class for objects used to display a cell value.
- @li wxGridCellStringRenderer: Renderer showing the cell as a text string.
- @li wxGridCellNumberRenderer: Renderer showing the cell as an integer number.
- @li wxGridCellFloatRenderer: Renderer showing the cell as a floating point
- number.
- @li wxGridCellBoolRenderer: Renderer showing the cell as checked or unchecked
- box.
- @li wxGridCellEditor: Base class for objects used to edit the cell value.
- @li wxGridCellStringEditor: Editor for cells containing text strings.
- @li wxGridCellNumberEditor: Editor for cells containing integer numbers.
- @li wxGridCellFloatEditor: Editor for cells containing floating point numbers.
- @li wxGridCellBoolEditor: Editor for boolean-valued cells.
- @li wxGridCellChoiceEditor: Editor allowing to choose one of the predefined
- strings (and possibly enter new one).
- @li wxGridEvent: The event sent by most of wxGrid actions.
- @li wxGridSizeEvent: The special event sent when a grid column or row is
- resized.
- @li wxGridRangeSelectEvent: The special event sent when a range of cells is
- selected in the grid.
- @li wxGridEditorCreatedEvent: The special event sent when a cell editor is
- created.
- @li wxGridSelection: The object efficiently representing the grid selection.
- @li wxGridTypeRegistry: Contains information about the data types supported by
- the grid.
- @section overview_grid_resizing Column and Row Sizes
- @b NB: This section will discuss the resizing of wxGrid rows only to avoid
- repetitions but everything in it also applies to grid columns, just replace @c
- Row in the method names with @c Col.
- Initially all wxGrid rows have the same height, which can be modified for all
- of them at once using wxGrid::SetDefaultRowSize(). However, unlike simpler
- controls such as wxListBox or wxListCtrl, wxGrid also allows its rows to be
- individually resized to have their own height using wxGrid::SetRowSize() (as a
- special case, a row may be hidden entirely by setting its size to 0, which is
- done by a helper wxGrid::HideRow() method). It is also possible to resize a row
- to fit its contents with wxGrid::AutoSizeRow() or do it for all rows at once
- with wxGrid::AutoSizeRows().
- Additionally, by default the user can also drag the row separator lines to
- resize the rows interactively. This can be forbidden completely by calling
- wxGrid::DisableDragRowSize() or just for the individual rows using
- wxGrid::DisableRowResize().
- If you do allow the user to resize the grid rows, it may be a good idea to save
- their heights and restore it when the grid is recreated the next time (possibly
- during a next program execution): the functions wxGrid::GetRowSizes() and
- wxGrid::SetRowSizes() can help with this, you will just need to serialize
- wxGridSizesInfo structure returned by the former in some way and deserialize it
- back before calling the latter.
