Interface TableModelHandler

tablemodel.go:106–137

TableModelHandler defines the methods that TableModel calls when it needs data.

// TableModelHandler defines the methods that TableModel
// calls when it needs data.
type TableModelHandler interface {
	// ColumnTypes returns a slice of value types of the data
	// stored in the model columns of the TableModel.
	// Each entry in the slice should ideally be a zero value for
	// the TableValue type of the column in question; the number
	// of elements in the slice determines the number of model
	// columns in the TableModel. The returned slice must remain
	// constant through the lifetime of the TableModel. This
	// method is not guaranteed to be called depending on the
	// system.
	ColumnTypes(m *TableModel) []TableValue

	// NumRows returns the number or rows in the TableModel.
	// This value must be non-negative.
	NumRows(m *TableModel) int

	// CellValue returns a TableValue corresponding to the model
	// cell at (row, column). The type of the returned TableValue
	// must match column's value type. Under some circumstances,
	// nil may be returned; refer to the various methods that add
	// columns to Table for details.
	CellValue(m *TableModel, row, column int) TableValue

	// SetCellValue changes the model cell value at (row, column)
	// in the TableModel. Within this function, either do nothing
	// to keep the current cell value or save the new cell value as
	// appropriate. After SetCellValue is called, the Table will
	// itself reload the table cell. Under certain conditions, the
	// TableValue passed in can be nil; refer to the various
	// methods that add columns to Table for details.
	SetCellValue(m *TableModel, row, column int, value TableValue)
