@section overview_grid_intro Introduction
|
|
|
|
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: a simple example
|
|
|
|
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");
|
|

|
|
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.
