Detailed Description

Developer defined methods for data retrieval and setting.

These methods get called whenever the associated uiTableModel needs to retrieve data or a uiTable wants to set data.

Warning: These methods are NOT allowed to change as soon as the uiTableModelHandler is associated with a uiTableModel.

Validate ranges

Validate types on each getter/setter call (? table columns only?)

Member Data Documentation

uiTableValue *(* uiTableModelHandler::CellValue) (uiTableModelHandler *mh, uiTableModel *m, int row, int column)

Returns the cell value for (row, column).

Make sure to use the uiTableValue constructors. The returned value must match the uiTableValueType defined in ColumnType().

Some columns may return NULL as a special value. Refer to the appropriate uiTableAppend*Column() documentation.

Note: uiTableValue objects are automatically freed when requested by a uiTable.

uiTableValueType(* uiTableModelHandler::ColumnType) (uiTableModelHandler *, uiTableModel *, int column)

Returns the column type in for of a uiTableValueType.

Warning: This value MUST remain constant throughout the lifetime of the uiTableModel.; This method is not guaranteed to be called depending on the system.

int(* uiTableModelHandler::NumColumns) (uiTableModelHandler *, uiTableModel *)

Returns the number of columns in the uiTableModel.

Warning: This value MUST remain constant throughout the lifetime of the uiTableModel.; This method is not guaranteed to be called depending on the system.

Todo:: strongly check column numbers and types on all platforms so these clauses can go away

int(* uiTableModelHandler::NumRows) (uiTableModelHandler *, uiTableModel *)

Returns the number of rows in the uiTableModel.

void(* uiTableModelHandler::SetCellValue) (uiTableModelHandler *, uiTableModel *, int, int, const uiTableValue *)

Sets the cell value for (row, column).

It is up to the handler to decide what to do with the value: change the model or reject the change, keeping the old value.

Some columns may call this function with NULL as a special value. Refer to the appropriate uiTableAppend*Column() documentation.

Note: uiTableValue objects are automatically freed upon return when set by a uiTable.
