## wxGrid

wxGrid and its related classes are used for displaying and editing tabular data. They provide a rich set of features for display, editing, and interacting with a variety of data sources. For simple applications, and to help you get started, wxGrid is the only class you need to refer to directly. It will set up default instances of the other classes and manage them for you. For more complex applications you can derive your own classes for custom grid views, grid data tables, cell editors and renderers. The wxGrid classes overview has examples of simple and more complex applications, explains the relationship between the various grid classes and has a summary of the keyboard shortcuts and mouse functions provided by wxGrid.

wxGrid has been greatly expanded and redesigned for wxWidgets 2.2 onwards. If you have been using the old wxGrid class you will probably want to have a look at the wxGrid classes overview to see how things have changed. The new grid classes are reasonably backward-compatible but there are some exceptions. There are also easier ways of doing many things compared to the previous implementation.

### wxGrid::wxGrid

wxGrid()

Default constructor

wxGrid(wxWindow* parent, wxWindowID id, const wxPoint& pos = wxDefaultPosition, const wxSize& size = wxDefaultSize, long style = wxWANTS_CHARS, const wxString& name = wxPanelNameStr)

Constructor to create a grid object. Call either wxGrid::CreateGrid or wxGrid::SetTable directly after this to initialize the grid before using it.

### wxGrid::~wxGrid

~wxGrid()

Destructor. This will also destroy the associated grid table unless you passed a table object to the grid and specified that the grid should not take ownership of the table (see wxGrid::SetTable).

### wxGrid::AppendCols

bool AppendCols(int numCols = 1, bool updateLabels = true)

Appends one or more new columns to the right of the grid and returns true if successful. The updateLabels argument is not used at present.

If you are using a derived grid table class you will need to override wxGridTableBase::AppendCols. See wxGrid::InsertCols for further information.

### wxGrid::AppendRows

bool AppendRows(int numRows = 1, bool updateLabels = true)

Appends one or more new rows to the bottom of the grid and returns true if successful. The updateLabels argument is not used at present.

If you are using a derived grid table class you will need to override wxGridTableBase::AppendRows. See wxGrid::InsertRows for further information.

### wxGrid::AutoSize

void AutoSize()

Automatically sets the height and width of all rows and columns to fit their contents.

Note
wxGrid sets up arrays to store individual row and column sizes when non-default sizes are used. The memory requirements for this could become prohibitive if your grid is very large.

### wxGrid::AutoSizeColumn

void AutoSizeColumn(int col, bool setAsMin = true)

Automatically sizes the column to fit its contents. If setAsMin is true the calculated width will also be set as the minimal width for the column.

Note
wxGrid sets up arrays to store individual row and column sizes when non-default sizes are used. The memory requirements for this could become prohibitive if your grid is very large.

### wxGrid::AutoSizeColumns

void AutoSizeColumns(bool setAsMin = true)

Automatically sizes all columns to fit their contents. If setAsMin is true the calculated widths will also be set as the minimal widths for the columns.

Note
wxGrid sets up arrays to store individual row and column sizes when non-default sizes are used. The memory requirements for this could become prohibitive if your grid is very large.

### wxGrid::AutoSizeRow

void AutoSizeRow(int row, bool setAsMin = true)

Automatically sizes the row to fit its contents. If setAsMin is true the calculated height will also be set as the minimal height for the row.

Note
wxGrid sets up arrays to store individual row and column sizes when non-default sizes are used. The memory requirements for this could become prohibitive if your grid is very large.

### wxGrid::AutoSizeRows

void AutoSizeRows(bool setAsMin = true)

Automatically sizes all rows to fit their contents. If setAsMin is true the calculated heights will also be set as the minimal heights for the rows.

Note
wxGrid sets up arrays to store individual row and column sizes when non-default sizes are used. The memory requirements for this could become prohibitive if your grid is very large.

### wxGrid::BeginBatch

void BeginBatch()

Increments the grid's batch count. When the count is greater than zero repainting of the grid is suppressed. Each call to BeginBatch must be matched by a later call to wxGrid::EndBatch. Code that does a lot of grid modification can be enclosed between BeginBatch and EndBatch calls to avoid screen flicker. The final EndBatch will cause the grid to be repainted.

### wxGrid::BlockToDeviceRect

wxRect BlockToDeviceRect(const wxGridCellCoords & topLeft, const wxGridCellCoords & bottomRight)

This function returns the rectangle that encloses the block of cells limited by TopLeft and BottomRight cell in device coords and clipped to the client size of the grid window.

### wxGrid::CanDragColMove

bool CanDragColMove()

Returns true if columns can be moved by dragging with the mouse. Columns can be moved by dragging on their labels.

### wxGrid::CanDragColSize

bool CanDragColSize()

Returns true if columns can be resized by dragging with the mouse. Columns can be resized by dragging the edges of their labels. If grid line dragging is enabled they can also be resized by dragging the right edge of the column in the grid cell area (see wxGrid::EnableDragGridSize).

### wxGrid::CanDragRowSize

bool CanDragRowSize()

Returns true if rows can be resized by dragging with the mouse. Rows can be resized by dragging the edges of their labels. If grid line dragging is enabled they can also be resized by dragging the lower edge of the row in the grid cell area (see wxGrid::EnableDragGridSize).

### wxGrid::CanDragGridSize

bool CanDragGridSize()

Return true if the dragging of grid lines to resize rows and columns is enabled or false otherwise.

### wxGrid::CanEnableCellControl

bool CanEnableCellControl() const

Returns true if the in-place edit control for the current grid cell can be used and false otherwise (e.g. if the current cell is read-only).

### wxGrid::CanHaveAttributes

bool CanHaveAttributes()

Do we have some place to store attributes in?

### wxGrid::CellToRect

wxRect CellToRect(int row, int col)

wxRect CellToRect(const wxGridCellCoords& coords)

Return the rectangle corresponding to the grid cell's size and position in logical coordinates.

### wxGrid::ClearGrid

void ClearGrid()

Clears all data in the underlying grid table and repaints the grid. The table is not deleted by this function. If you are using a derived table class then you need to override wxGridTableBase::Clear for this function to have any effect.

### wxGrid::ClearSelection

void ClearSelection()

Deselects all cells that are currently selected.

### wxGrid::CreateGrid

bool CreateGrid(int numRows, int numCols, wxGrid::wxGridSelectionModes selmode = wxGrid::wxGridSelectCells)

Creates a grid with the specified initial number of rows and columns. Call this directly after the grid constructor. When you use this function wxGrid will create and manage a simple table of string values for you. All of the grid data will be stored in memory.

For applications with more complex data types or relationships, or for dealing with very large datasets, you should derive your own grid table class and pass a table object to the grid with wxGrid::SetTable.

### wxGrid::DeleteCols

bool DeleteCols(int pos = 0, int numCols = 1, bool updateLabels = true)

Deletes one or more columns from a grid starting at the specified position and returns true if successful. The updateLabels argument is not used at present.

If you are using a derived grid table class you will need to override wxGridTableBase::DeleteCols. See wxGrid::InsertCols for further information.

### wxGrid::DeleteRows

bool DeleteRows(int pos = 0, int numRows = 1, bool updateLabels = true)

Deletes one or more rows from a grid starting at the specified position and returns true if successful. The updateLabels argument is not used at present.

If you are using a derived grid table class you will need to override wxGridTableBase::DeleteRows. See wxGrid::InsertRows for further information.

### wxGrid::DisableCellEditControl

void DisableCellEditControl()

Disables in-place editing of grid cells. Equivalent to calling EnableCellEditControl(false).

### wxGrid::EnableDragColSize

void EnableDragColSize(bool enable = true)

Enables or disables column sizing by dragging with the mouse.

### wxGrid::EnableDragColMove

### wxGrid::EnableDragRowSize

void EnableDragRowSize(bool enable = true)

Enables or disables row sizing by dragging with the mouse.

### wxGrid::EnableEditing

void EnableEditing(bool edit)

If the edit argument is false this function sets the whole grid as read-only. If the argument is true the grid is set to the default state where cells may be editable. In the default state you can set single grid cells and whole rows and columns to be editable or read-only via wxGridCellAttribute::SetReadOnly. For single cells you can also use the shortcut function wxGrid::SetReadOnly.

For more information about controlling grid cell attributes see the wxGridCellAttr cell attribute class and the wxGrid classes overview.

### wxGrid::EnableGridLines

void EnableGridLines(bool enable = true)

Turns the drawing of grid lines on or off.

### wxGrid::EndBatch

void EndBatch()

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

### wxGrid::Fit

void Fit()

Overridden wxWindow method.

### wxGrid::ForceRefresh

void ForceRefresh()

Causes immediate repainting of the grid. Use this instead of the usual wxWindow::Refresh.

### wxGrid::GetBatchCount

The width argument must be higher than the minimimal acceptable column width, see wxGrid::GetColMinimalAcceptableWidth.

### wxGrid::SetColMinimalAcceptableWidth

void SetColMinimalAcceptableWidth(int width)

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

Automatically sizes the column to fit its contents. If setAsMin is true the calculated width will also be set as the minimal width for the column.

Note
wxGrid sets up arrays to store individual row and column sizes when non-default sizes are used. The memory requirements for this could become prohibitive if your grid is very large.

### wxGrid::SetDefaultCellAlignment

void SetDefaultCellAlignment(int horiz, int vert)

### wxGrid::SetRowMinimalHeight

void SetRowMinimalHeight(int row, int height)

Sets the minimal height for the specified row. This should normally be called when creating the grid because it will not resize a row that is already shorter than the minimal height. The height argument must be higher than the minimimal acceptable row height, see wxGrid::GetRowMinimalAcceptableHeight.

### wxGrid::SetRowMinimalAcceptableHeight

void SetRowMinimalAcceptableHeight(int height)

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

### wxGrid::SetRowSize

void SetRowSize(int row, int height)

Sets the height of the specified row.

This function does not refresh the grid. If you are calling it outside of a BeginBatch / EndBatch block you can use wxGrid::ForceRefresh to see the changes.

Automatically sizes the column to fit its contents. If setAsMin is true the calculated width will also be set as the minimal width for the column.

Note
