    • Method Detail

      • removeColumn

        void removeColumn​(TableColumn column)
        Deletes the TableColumn column from the tableColumns array. This method will do nothing if column is not in the table's column list. This method posts a columnRemoved event to its listeners.
        Parameters:
        column - the TableColumn to be removed
        See Also:
        addColumn(javax.swing.table.TableColumn)

      • moveColumn

        void moveColumn​(int columnIndex,
                int newIndex)
        Moves the column and its header at columnIndex to newIndex. The old column at columnIndex will now be found at newIndex. The column that used to be at newIndex is shifted left or right to make room. This will not move any columns if columnIndex equals newIndex. This method posts a columnMoved event to its listeners.
        Parameters:
        columnIndex - the index of column to be moved
        newIndex - index of the column's new location
        Throws:
        IllegalArgumentException - if columnIndex or newIndex are not in the valid range

      • setColumnMargin

        void setColumnMargin​(int newMargin)
        Sets the TableColumn's column margin to newMargin. This method posts a columnMarginChanged event to its listeners.
        Parameters:
        newMargin - the width, in pixels, of the new column margins
        See Also:
        getColumnMargin()

      • getColumnCount

        int getColumnCount()
        Returns the number of columns in the model.
        Returns:
        the number of columns in the model

      • getColumns

        Enumeration<TableColumn> getColumns()
        Returns an Enumeration of all the columns in the model.
        Returns:
        an Enumeration of all the columns in the model

      • getColumnIndex

        int getColumnIndex​(Object columnIdentifier)
        Returns the index of the first column in the table whose identifier is equal to identifier, when compared using equals.
        Parameters:
        columnIdentifier - the identifier object
        Returns:
        the index of the first table column whose identifier is equal to identifier
        Throws:
        IllegalArgumentException - if identifier is null, or no TableColumn has this identifier
        See Also:
        getColumn(int)

      • getColumn

        TableColumn getColumn​(int columnIndex)
        Returns the TableColumn object for the column at columnIndex.
        Parameters:
        columnIndex - the index of the desired column
        Returns:
        the TableColumn object for the column at columnIndex

      • getColumnMargin

        int getColumnMargin()
        Returns the width between the cells in each column.
        Returns:
        the margin, in pixels, between the cells

      • getColumnIndexAtX

        int getColumnIndexAtX​(int xPosition)
        Returns the index of the column that lies on the horizontal point, xPosition; or -1 if it lies outside the any of the column's bounds. In keeping with Swing's separable model architecture, a TableColumnModel does not know how the table columns actually appear on screen. The visual presentation of the columns is the responsibility of the view/controller object using this model (typically JTable). The view/controller need not display the columns sequentially from left to right. For example, columns could be displayed from right to left to accommodate a locale preference or some columns might be hidden at the request of the user. Because the model does not know how the columns are laid out on screen, the given xPosition should not be considered to be a coordinate in 2D graphics space. Instead, it should be considered to be a width from the start of the first column in the model. If the column index for a given X coordinate in 2D space is required, JTable.columnAtPoint can be used instead.
        Parameters:
        xPosition - width from the start of the first column in the model.
        Returns:
        the index of the column; or -1 if no column is found
        See Also:
        JTable.columnAtPoint(java.awt.Point)

      • getTotalColumnWidth

        int getTotalColumnWidth()
        Returns the total width of all the columns.
        Returns:
        the total computed width of all columns

      • setColumnSelectionAllowed

        void setColumnSelectionAllowed​(boolean flag)
        Sets whether the columns in this model may be selected.
        Parameters:
        flag - true if columns may be selected; otherwise false
        See Also:
        getColumnSelectionAllowed()

      • getColumnSelectionAllowed

        boolean getColumnSelectionAllowed()
        Returns true if columns may be selected.
        Returns:
        true if columns may be selected
        See Also:
        setColumnSelectionAllowed(boolean)

      • getSelectedColumns

        int[] getSelectedColumns()
        Returns an array of indicies of all selected columns.
        Returns:
        an array of integers containing the indicies of all selected columns; or an empty array if nothing is selected

        int getSelectedColumnCount()
        Returns the number of selected columns.
        Returns:
