wxGrid - Functions for wxGrid class
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 overview_grid 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.
A wxGridTableBase (not implemented in wx) class holds the actual data to be displayed by a wxGrid class. One or more wxGrid classes may act as a view for one table class. The default table class is called wxGridStringTable (not implemented in wx) and holds an array of strings. An instance of such a class is created by createGrid/4.
wxGridCellRenderer is the abstract base class for rendering contents in a cell. The following renderers are predefined:
The look of a cell can be further defined using wxGridCellAttr. An object of this type may be returned by wxGridTableBase::GetAttr() (not implemented in wx).
wxGridCellEditor is the abstract base class for editing the value of a cell. The following editors are predefined:
Please see wxGridEvent, wxGridSizeEvent (not implemented in wx), wxGridRangeSelectEvent (not implemented in wx), and wxGridEditorCreatedEvent (not implemented in wx) for the documentation of all event types you can use with wxGrid.
See: Overview grid, wxGridUpdateLocker (not implemented in wx)
This class is derived (and can use functions) from: wxScrolledWindow wxPanel wxWindow wxEvtHandler
wxWidgets docs: wxGrid
wxGrid() = wx:wx_object()
new() -> wxGrid()
Default constructor.
You must call Create() (not implemented in wx) to really create the grid window and also call createGrid/4 or SetTable() (not implemented in wx) or AssignTable() (not implemented in wx) to initialize its contents.
new(Parent, Id) -> wxGrid()
Types:
new(Parent, Id, Options :: [Option]) -> wxGrid()
Types:
Constructor creating the grid window.
You must call either createGrid/4 or SetTable() (not implemented in wx) or AssignTable() (not implemented in wx) to initialize the grid contents before using it.
destroy(This :: wxGrid()) -> ok
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 SetTable() (not implemented in wx)).
appendCols(This) -> boolean()
Types:
appendCols(This, Options :: [Option]) -> boolean()
Types:
Appends one or more new columns to the right of the grid.
The updateLabels argument is not used at present. If you are using a derived grid table class you will need to override wxGridTableBase::AppendCols() (not implemented in wx). See insertCols/2 for further information.
Return: true on success or false if appending columns failed.
appendRows(This) -> boolean()
Types:
appendRows(This, Options :: [Option]) -> boolean()
Types:
Appends one or more new rows to the bottom of the grid.
The updateLabels argument is not used at present. If you are using a derived grid table class you will need to override wxGridTableBase::AppendRows() (not implemented in wx). See insertRows/2 for further information.
Return: true on success or false if appending rows failed.
autoSize(This) -> ok
Types:
Automatically sets the height and width of all rows and columns to fit their contents.
autoSizeColumn(This, Col) -> ok
Types:
autoSizeColumn(This, Col, Options :: [Option]) -> ok
Types:
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.
autoSizeColumns(This) -> ok
Types:
autoSizeColumns(This, Options :: [Option]) -> ok
Types:
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.
autoSizeRow(This, Row) -> ok
Types:
autoSizeRow(This, Row, Options :: [Option]) -> ok

Types:
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.
beginBatch(This) -> ok
Types:
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 endBatch/1. Code that does a lot of grid modification can be enclosed between beginBatch/1 and endBatch/1 calls to avoid screen flicker. The final endBatch/1 call will cause the grid to be repainted.
Notice that you should use wxGridUpdateLocker (not implemented in wx) which ensures that there is always a matching endBatch/1 call for this beginBatch/1 if possible instead of calling this method directly.
blockToDeviceRect(This, TopLeft, BottomRight) ->
{X :: integer(),
Y :: integer(),
W :: integer(),
H :: integer()}
Types:
Convert grid cell coordinates to grid window pixel coordinates.
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.
Since: 3.1.3 Parameter gridWindow has been added.
See: cellToRect/3

See: canDragGridSize/1, canDragRowSize/2
Since: 3.1.4
canDragColSize(This, Col) -> boolean()
Types:
Returns true if the given column can be resized by dragging with the mouse.
This function returns true if resizing the columns interactively is globally enabled, i.e. if disableDragColSize/1 hadn't been called, and if this column wasn't explicitly marked as non-resizable with DisableColResize() (not implemented in wx).
canDragRowSize(This, Row) -> boolean()
Types:
Returns true if the given row can be resized by dragging with the mouse.
This is the same as canDragColSize/2 but for rows.
canDragGridSize(This) -> boolean()
Types:
Return true if the dragging of grid lines to resize rows and columns is enabled or false otherwise.
canEnableCellControl(This) -> boolean()
Types:
Returns true if the in-place edit control for the current grid cell can be used and false otherwise.
This function always returns false for the read-only cells.
cellToRect(This, Coords) ->
{X :: integer(),
Y :: integer(),
W :: integer(),
H :: integer()}
Types:
Return the rectangle corresponding to the grid cell's size and position in logical coordinates.

See: blockToDeviceRect/3
clearGrid(This) -> ok
Types:
Clears all data in the underlying grid table and repaints the grid.

clearSelection(This) -> ok
Types:
Deselects all cells that are currently selected.
createGrid(This, NumRows, NumCols) -> boolean()
Types:
createGrid(This, NumRows, NumCols, Options :: [Option]) ->
boolean()
Types:
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 SetTable() (not implemented in wx) or AssignTable() (not implemented in wx).
deleteCols(This) -> boolean()
Types:
deleteCols(This, Options :: [Option]) -> boolean()
Types:
Deletes one or more columns from a grid starting at the specified position.
The updateLabels argument is not used at present. If you are using a derived grid table class you will need to override wxGridTableBase::DeleteCols() (not implemented in wx). See insertCols/2 for further information.
Return: true on success or false if deleting columns failed.
deleteRows(This) -> boolean()
Types:
deleteRows(This, Options :: [Option]) -> boolean()
Types:
Deletes one or more rows from a grid starting at the specified position.

Types:
Disables column sizing by dragging with the mouse.
Equivalent to passing false to enableDragColSize/2.
disableDragGridSize(This) -> ok
Types:
Disable mouse dragging of grid lines to resize rows and columns.
Equivalent to passing false to enableDragGridSize/2
disableDragRowSize(This) -> ok
Types:
Disables row sizing by dragging with the mouse.
Equivalent to passing false to enableDragRowSize/2.
enableCellEditControl(This) -> ok
Types:
enableCellEditControl(This, Options :: [Option]) -> ok
Types:
Enables or disables in-place editing of grid cell data.
Enabling in-place editing generates wxEVT_GRID_EDITOR_SHOWN and, if it isn't vetoed by the application, shows the in-place editor which allows the user to change the cell value.
Disabling in-place editing does nothing if the in-place editor isn't currently shown, otherwise the wxEVT_GRID_EDITOR_HIDDEN event is generated but, unlike the "shown" event, it can't be vetoed and the in-place editor is dismissed unconditionally.
Note that it is an error to call this function if the current cell is read-only, use canEnableCellControl/1 to check for this precondition.
enableDragColSize(This) -> ok
Types:
enableDragColSize(This, Options :: [Option]) -> ok
Types:
Enables or disables column sizing by dragging with the mouse.
See: DisableColResize() (not implemented in wx)

Types:
enableDragGridSize(This, Options :: [Option]) -> ok
Types:
Enables or disables row and column resizing by dragging gridlines with the mouse.
enableDragRowSize(This) -> ok
Types:
enableDragRowSize(This, Options :: [Option]) -> ok
Types:
Enables or disables row sizing by dragging with the mouse.
See: DisableRowResize() (not implemented in wx)
enableEditing(This, Edit) -> ok
Types:
Makes the grid globally editable or read-only.
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 wxGridCellAttr:setReadOnly/2. For single cells you can also use the shortcut function setReadOnly/4.
For more information about controlling grid cell attributes see the wxGridCellAttr class and the overview_grid.
enableGridLines(This) -> ok
Types:
enableGridLines(This, Options :: [Option]) -> ok
Types:
Turns the drawing of grid lines on or off.
endBatch(This) -> ok
Types:
Decrements the grid's batch count.
When the count is greater than zero repainting of the grid is suppressed. Each previous call to beginBatch/1 must be matched by a later call to endBatch/1. Code that does a lot of grid modification can be enclosed between beginBatch/1 and endBatch/1 calls to avoid screen flicker. The final endBatch/1 will cause the grid to be repainted.
See: wxGridUpdateLocker (not implemented in wx)
fit(This) -> ok
Types:
Overridden wxWindow method.
forceRefresh(This) -> ok
Types:
Causes immediate repainting of the grid.
Use this instead of the usual wxWindow:refresh/2.

Notice that the same may be achieved in a usually simpler way by associating a custom editor with the given cell or cells.
The caller must call DecRef() on the returned pointer.
getDefaultEditorForCell(This, Row, Col) ->
wxGridCellEditor:wxGridCellEditor()
Types:

getSelectedCells(This) -> [{R :: integer(), C :: integer()}]
Types:
Returns an array of individually selected cells.
Notice that this array does not contain all the selected cells in general as it doesn't include the cells selected as part of column, row or block selection. You must use this method, getSelectedCols/1, getSelectedRows/1 and getSelectionBlockTopLeft/1 and getSelectionBlockBottomRight/1 methods to obtain the entire selection in general.
Please notice this behaviour is by design and is needed in order to support grids of arbitrary size (when an entire column is selected in a grid with a million of columns, we don't want to create an array with a million of entries in this function, instead it returns an empty array and getSelectedCols/1 returns an array containing one element).
The function can be slow for the big grids, use GetSelectedBlocks() (not implemented in wx) in the new code.
getSelectedCols(This) -> [integer()]
Types:
Returns an array of selected columns.
Please notice that this method alone is not sufficient to find all the selected columns as it contains only the columns which were individually selected but not those being part of the block selection or being selected in virtue of all of their cells being selected individually, please see getSelectedCells/1 for more details.
The function can be slow for the big grids, use GetSelectedBlocks() (not implemented in wx) in the new code.
getSelectedRows(This) -> [integer()]
Types:
Returns an array of selected rows.
Please notice that this method alone is not sufficient to find all the selected rows as it contains only the rows which were individually selected but not those being part of the block selection or being selected in virtue of all of their cells being selected individually, please see getSelectedCells/1 for more details.
The function can be slow for the big grids, use GetSelectedBlocks() (not implemented in wx) in the new code.
getSelectionBackground(This) -> wx:wx_colour4()
Types:
Returns the colour used for drawing the selection background.
getSelectionBlockTopLeft(This) ->
[{R :: integer(), C :: integer()}]
Types:
Returns an array of the top left corners of blocks of selected cells.
Please see getSelectedCells/1 for more information about the selection representation in wxGrid.
The function can be slow for the big grids, use GetSelectedBlocks() (not implemented in wx) in the new code.
See: getSelectionBlockBottomRight/1
getSelectionBlockBottomRight(This) ->
[{R :: integer(), C :: integer()}]
Types:
Returns an array of the bottom right corners of blocks of selected cells.
Please see getSelectedCells/1 for more information about the selection representation in wxGrid.

Types:
Return the main grid window containing the grid cells.
This window is always shown.

Types:
Return the row labels window.
This window is not shown if the row labels were hidden using HideRowLabels() (not implemented in wx).
getGridColLabelWindow(This) -> wxWindow:wxWindow()
Types:
Return the column labels window.
This window is not shown if the columns labels were hidden using HideColLabels() (not implemented in wx).
Depending on whether UseNativeColHeader() (not implemented in wx) was called or not this can be either a wxHeaderCtrl (not implemented in wx) or a plain wxWindow. This function returns a valid window pointer in either case but in the former case you can also use GetGridColHeader() (not implemented in wx) to access it if you need wxHeaderCtrl-specific functionality.
getGridCornerLabelWindow(This) -> wxWindow:wxWindow()
Types:
Return the window in the top left grid corner.
This window is shown only of both columns and row labels are shown and normally doesn't contain anything. Clicking on it is handled by wxGrid however and can be used to select the entire grid.
hideCellEditControl(This) -> ok
Types:
Hides the in-place cell edit control.
insertCols(This) -> boolean()
Types:
insertCols(This, Options :: [Option]) -> boolean()
Types:
Inserts one or more new columns into a grid with the first new column at the specified position.
Notice that inserting the columns in the grid requires grid table cooperation: when this method is called, grid object begins by requesting the underlying grid table to insert new columns. If this is successful the table notifies the grid and the grid updates the display. For a default grid (one where you have called createGrid/4) this process is automatic. If you are using a custom grid table (specified with SetTable() (not implemented in wx) or AssignTable() (not implemented in wx)) then you must override wxGridTableBase::InsertCols() (not implemented in wx) in your derived table class.
Return: true if the columns were successfully inserted, false if an error occurred (most likely the table couldn't be updated).
insertRows(This) -> boolean()
Types:
insertRows(This, Options :: [Option]) -> boolean()
Types:
Inserts one or more new rows into a grid with the first new row at the specified position.
Notice that you must implement wxGridTableBase::InsertRows() (not implemented in wx) if you use a grid with a custom table, please see insertCols/2 for more information.
Return: true if the rows were successfully inserted, false if an error occurred (most likely the table couldn't be updated).

If a block of cells was previously selected it will expand if the argument is true or be cleared if the argument is false.
moveCursorUp(This, ExpandSelection) -> boolean()
Types:
Moves the grid cursor up by one row.
If a block of cells was previously selected it will expand if the argument is true or be cleared if the argument is false.
moveCursorDownBlock(This, ExpandSelection) -> boolean()
Types:
Moves the grid cursor down in the current column such that it skips to the beginning or end of a block of non-empty cells.
If a block of cells was previously selected it will expand if the argument is true or be cleared if the argument is false.
moveCursorLeftBlock(This, ExpandSelection) -> boolean()
Types:
Moves the grid cursor left in the current row such that it skips to the beginning or end of a block of non-empty cells.
If a block of cells was previously selected it will expand if the argument is true or be cleared if the argument is false.
moveCursorRightBlock(This, ExpandSelection) -> boolean()
Types:
Moves the grid cursor right in the current row such that it skips to the beginning or end of a block of non-empty cells.
If a block of cells was previously selected it will expand if the argument is true or be cleared if the argument is false.
moveCursorUpBlock(This, ExpandSelection) -> boolean()
Types:
Moves the grid cursor up in the current column such that it skips to the beginning or end of a block of non-empty cells.
If a block of cells was previously selected it will expand if the argument is true or be cleared if the argument is false.

Types:
Moves the grid cursor up by some number of rows so that the previous top visible row becomes the bottom visible row.
registerDataType(This, TypeName, Renderer, Editor) -> ok
Types:
Register a new data type.
The data types allow to naturally associate specific renderers and editors to the cells containing values of the given type. For example, the grid automatically registers a data type with the name wxGRID_VALUE_STRING which uses wxGridCellStringRenderer and wxGridCellTextEditor as its renderer and editor respectively - this is the data type used by all the cells of the default wxGridStringTable (not implemented in wx), so this renderer and editor are used by default for all grid cells.
However if a custom table returns wxGRID_VALUE_BOOL from its wxGridTableBase::GetTypeName() (not implemented in wx) method, then wxGridCellBoolRenderer and wxGridCellBoolEditor are used for it because the grid also registers a boolean data type with this name.
And as this mechanism is completely generic, you may register your own data types using your own custom renderers and editors. Just remember that the table must identify a cell as being of the given type for them to be used for this cell.
saveEditControlValue(This) -> ok
Types:
Sets the value of the current grid cell to the current in-place edit control value.
This is called automatically when the grid cursor moves from the current cell to a new cell. It is also a good idea to call this function when closing a grid since any edits to the final cell location will not be saved otherwise.

Selects all cells in the grid.
selectBlock(This, TopLeft, BottomRight) -> ok
Types:
selectBlock(This, TopLeft, BottomRight, Options :: [Option]) -> ok

Types:
Selects the specified row.
If addToSelected is false then any existing selection will be deselected; if true the row will be added to the existing selection.
This method won't select anything if the current selection mode is wxGridSelectColumns.
setCellAlignment(This, Row, Col, Horiz, Vert) -> ok
Types:
Sets the horizontal and vertical alignment for grid cell text at the specified location.

Sets the text colour for the given cell.
setCellValue(This, Coords, S) -> ok
Types:
Sets the string value for the cell at the specified location.
For simple applications where a grid object automatically uses a default grid table of string values you use this function together with getCellValue/3 to access cell values. For more complex applications where you have derived your own grid table class that contains various data types (e.g. numeric, boolean or user-defined custom types) then you only use this function for those cells that contain string values.
See wxGridTableBase::CanSetValueAs() (not implemented in wx) and the overview_grid for more information.
setCellValue(This, Row, Col, S) -> ok
Types:
Sets the string value for the cell at the specified location.

setColFormatCustom(This, Col, TypeName) -> ok
Types:
Sets the specified column to display data in a custom format.
This method provides an alternative to defining a custom grid table which would return typeName from its GetTypeName() method for the cells in this column: while it doesn't really change the type of the cells in this column, it does associate the renderer and editor used for the cells of the specified type with them.
See the overview_grid for more information on working with custom data types.
setColLabelAlignment(This, Horiz, Vert) -> ok
Types:
Sets the horizontal and vertical alignment of column label text.

setDefaultRowSize(This, Height) -> ok
Types:
setDefaultRowSize(This, Height, Options :: [Option]) -> ok
Types:
Sets the default height for rows in the grid.
This will only affect rows subsequently added to the grid unless resizeExistingRows is true.
If height is less than getRowMinimalAcceptableHeight/1, then the minimal acceptable height is used instead of it.
setGridCursor(This, Coords) -> ok
Types:
Set the grid cursor to the specified cell.
The grid cursor indicates the current cell and can be moved by the user using the arrow keys or the mouse.
Calling this function generates a wxEVT_GRID_SELECT_CELL event and if the event handler vetoes this event, the cursor is not moved.
This function doesn't make the target call visible, use GoToCell() (not implemented in wx) to do this.
setGridCursor(This, Row, Col) -> ok
Types:
Set the grid cursor to the specified cell.
The grid cursor indicates the current cell and can be moved by the user using the arrow keys or the mouse.
Calling this function generates a wxEVT_GRID_SELECT_CELL event and if the event handler vetoes this event, the cursor is not moved.
This function doesn't make the target call visible, use GoToCell() (not implemented in wx) to do this.

If width equals wxGRID_AUTOSIZE then width is calculated automatically so that no label is truncated. Note that this could be slow for a large table.
setRowLabelValue(This, Row, Value) -> ok
Types:
Sets the value for the given row label.
If you are using a derived grid table you must override wxGridTableBase::SetRowLabelValue() (not implemented in wx) for this to have any effect.

Set the colour to be used for drawing the selection foreground.
setSelectionMode(This, Selmode) -> ok
Types:
Set the selection behaviour of the grid.
The existing selection is converted to conform to the new mode if possible and discarded otherwise (e.g. any individual selected cells are deselected if the new mode allows only the selection of the entire rows or columns).
showCellEditControl(This) -> ok
Types:
Displays the active in-place cell edit control for the current cell after it was hidden.
This method should only be called after calling hideCellEditControl/1, to start editing the current grid cell use enableCellEditControl/2 instead.
xToCol(This, X) -> integer()
Types:
xToCol(This, X, Options :: [Option]) -> integer()
Types:
Returns the column at the given pixel position depending on the window.
Return: The column index or wxNOT_FOUND.
xToEdgeOfCol(This, X) -> integer()
Types:
Returns the column whose right hand edge is close to the given logical x position.
If no column edge is near to this position wxNOT_FOUND is returned.

If no row edge is near to this position wxNOT_FOUND is returned.
yToRow(This, Y) -> integer()
Types:
yToRow(This, Y, Options :: [Option]) -> integer()
Types:
Returns the grid row that corresponds to the logical y coordinate.
The parameter gridWindow is new since wxWidgets 3.1.3. If it is specified, i.e. non-NULL, only the cells of this window are considered, i.e. the function returns wxNOT_FOUND if y is out of bounds.
If gridWindow is NULL, the function returns wxNOT_FOUND only if there is no row at all at the y position.
