      • columnContainsComponent

        public static boolean columnContainsComponent​(java.awt.Container container,
                                              int columnIndex)
        Checks and answers whether the given FormLayout container contains a component in the specified column.

        For every container child component, we look up the associated CellConstraints object from the layout and compare its horizontal grid origin with the specified column index.

        Parameters:
        container - the layout container
        columnIndex - the index of the column to test
        Returns:
        true if the column contains a component, false otherwise
        Throws:
        java.lang.IllegalArgumentException - if the container's layout is not a FormLayout

      • rowContainsComponent

        public static boolean rowContainsComponent​(java.awt.Container container,
                                           int rowIndex)
        Checks and answers whether the given FormLayout container contains a component in the specified row.

        For every container child component, we look up the associated CellConstraints object from the layout and compare its vertical grid origin with the specified row index.

        Parameters:
        container - the layout container
        rowIndex - the index of the row to test
        Returns:
        true if the row contains a component, false otherwise
        Throws:
        java.lang.IllegalArgumentException - if the container's layout is not a FormLayout

      • isGroupedColumn

        public static boolean isGroupedColumn​(FormLayout layout,
                                      int columnIndex)
        Checks and answers whether the specified column is grouped in the given FormLayout. A column col is grouped, if and only if there's a column group group that includes col's index.
        Parameters:
        layout - the layout to be inspected
        columnIndex - the index of the column to be checked
        Returns:
        true if the column is grouped, false if not

      • isGroupedRow

        public static boolean isGroupedRow​(FormLayout layout,
                                   int rowIndex)
        Checks and answers whether the specified row is grouped in the given FormLayout. A row row is grouped, if and only if there's a row group group that includes row's index.
        Parameters:
        layout - the layout to be inspected
        rowIndex - the index of the row to be checked
        Returns:
        true if the column is grouped, false if not
