Enclosing class:

FlatTableCellBorder

public static class FlatTableCellBorder.Selected
extends FlatTableCellBorder

Border for selected cell that uses margins and paints focus indicator border. The focus indicator is shown under following conditions:

• always if enabled via UI property Table.showCellFocusIndicator=true
• for row selection mode if exactly one row is selected and at least one cell in that row is editable
• for column selection mode if exactly one column is selected and at least one cell in that column is editable
• never for cell selection mode

The reason for this logic is to hide the focus indicator when it is not needed, and only show it when there are editable cells and the user needs to know which cell is focused to start editing.

To avoid possible performance issues, checking for editable cells is limited to maxCheckCellsEditable. If there are more cells to check, the focus indicator is always shown.
