Interface TableContent

table.go:234–276

TableContent defines a Table's data. You may replace a Table's default implementation with your own using the Table.SetContent() function. This will allow you to turn Table into a view of your own data structure. The Table.Draw() function, which is called when the screen is updated, will then use th

// package (provided that users of the package don't call Table.Draw() in a
// separate goroutine, which would be uncommon and is not encouraged).
type TableContent interface {
	// Return the cell at the given position or nil if there is no cell. The
	// row and column arguments start at 0 and end at what GetRowCount() and
	// GetColumnCount() return, minus 1.
	GetCell(row, column int) *TableCell

	// Return the total number of rows in the table.
	GetRowCount() int

	// Return the total number of columns in the table.
	GetColumnCount() int

	// The following functions are provided for completeness reasons as the
	// original Table implementation was not read-only. If you do not wish to
	// forward modifying operations to your data, you may opt to leave these
	// functions empty. To make this easier, you can include the
	// TableContentReadOnly type in your struct. See also the
	// demos/table/virtualtable example.

	// Set the cell at the given position to the provided cell.
	SetCell(row, column int, cell *TableCell)

	// Remove the row at the given position by shifting all following rows up
	// by one. Out of range positions may be ignored.
	RemoveRow(row int)

	// Remove the column at the given position by shifting all following columns
	// left by one. Out of range positions may be ignored.
	RemoveColumn(column int)

	// Insert a new empty row at the given position by shifting all rows at that
	// position and below down by one. Implementers may decide what to do with
	// out of range positions.
	InsertRow(row int)

	// Insert a new empty column at the given position by shifting all columns
	// at that position and to the right by one to the right. Implementers may
	// decide what to do with out of range positions.
	InsertColumn(column int)

	// Remove all table data.
	Clear()
}

// TableContentReadOnly is an empty struct which implements the write operations
// of the TableContent interface. None of the implemented functions do anything.
