      • hasFocus

        public boolean hasFocus()
        Returns true if the cell identified by this adapter currently has focus. Otherwise, it returns false.
        Specified by:
        hasFocus in class ComponentAdapter
        Returns:
        true if the cell identified by this adapter currently has focus; Otherwise, return false
      • getRowCount

        public int getRowCount()
        Returns the number of rows in the target's data model.
        Overrides:
        getRowCount in class ComponentAdapter
        Returns:
        the number of rows in the target's data model.
      • getValueAt

        public Object getValueAt​(int row,
                                 int column)
        Returns the value of the target component's cell identified by the specified row and column in model coordinates.
        Specified by:
        getValueAt in class ComponentAdapter
        Parameters:
        row - in model coordinates
        column - in model coordinates
        Returns:
        the value of the target component's cell identified by the specified row and column
      • getStringAt

        public String getStringAt​(int row,
                                  int column)
        Returns the String representation of the value of the cell identified by the row specified row and column in model coordinates.

        This implementation messages the StringValue.TO_STRING with the valueAt, subclasses should re-implement and use the api appropriate for the target component type.

        This is implemented to query the table's StringValueRegistry for an appropriate StringValue and use that for getting the string representation.

        Overrides:
        getStringAt in class ComponentAdapter
        Parameters:
        row - in model coordinates
        column - in model coordinates
        Returns:
        the value of the target component's cell identified by the specified row and column

        Overrides:
        getCellBounds in class ComponentAdapter
        Returns:
        the bounds of the cell identified by this adapter
      • isCellEditable
