• Constructor Detail

  • TableView

    public TableView(Element elem)

    Constructs a TableView for the given element.

    Parameters:

    elem - the element that this view is responsible for

• Method Detail

  • createTableRow

    protected TableView.TableRow createTableRow(Element elem)

    Creates a new table row.

    Parameters:

    elem - an element

    Returns:

    the row

  • createTableCell

    @Deprecated
    protected TableView.TableCell createTableCell(Element elem)

    Deprecated. Table cells can now be any arbitrary View implementation and should be produced by the ViewFactory rather than the table.

    Parameters:

    elem - an element

    Returns:

    the cell

  • forwardUpdate

    protected void forwardUpdate(DocumentEvent.ElementChange ec,
     DocumentEvent e,
     Shape a,
     ViewFactory f)

    Description copied from class: BoxView
    Forwards the given DocumentEvent to the child views that need to be notified of the change to the model. If a child changed its requirements and the allocation was valid prior to forwarding the portion of the box from the starting child to the end of the box will be repainted.

    Overrides:

    forwardUpdate in class BoxView

    Parameters:

    ec - changes to the element this view is responsible for (may be null if there were no changes)

    e - the change information from the associated document

    a - the current allocation of the view

    f - the factory to use to rebuild if the view has children

    See Also:

    View.insertUpdate(javax.swing.event.DocumentEvent, java.awt.Shape, javax.swing.text.ViewFactory), View.removeUpdate(javax.swing.event.DocumentEvent, java.awt.Shape, javax.swing.text.ViewFactory), View.changedUpdate(javax.swing.event.DocumentEvent, java.awt.Shape, javax.swing.text.ViewFactory)

  • replace

    public void replace(int offset,
     int length,
     View[] views)

    Change the child views. This is implemented to provide the superclass behavior and invalidate the grid so that rows and columns will be recalculated.

    Overrides:

    replace in class BoxView

    Parameters:

    offset - the starting index into the child views to insert the new views; this should be a value >= 0 and <= getViewCount

    length - the number of existing child views to remove; This should be a value >= 0 and <= (getViewCount() - offset)

    views - the child views to add; this value can be nullto indicate no children are being added (useful to remove)

  • layoutColumns

    protected void layoutColumns(int targetSpan,
     int[] offsets,
     int[] spans,
     SizeRequirements[] reqs)

    Lays out the columns to fit within the given target span. Returns the results through offsets and spans.

    Parameters:

    targetSpan - the given span for total of all the table columns

    reqs - the requirements desired for each column. This is the column maximum of the cells minimum, preferred, and maximum requested span

    spans - the return value of how much to allocated to each column

    offsets - the return value of the offset from the origin for each column

  • layoutMinorAxis

    protected void layoutMinorAxis(int targetSpan,
     int axis,
     int[] offsets,
     int[] spans)

    Perform layout for the minor axis of the box (i.e. the axis orthogonal to the axis that it represents). The results of the layout should be placed in the given arrays which represent the allocations to the children along the minor axis. This is called by the superclass whenever the layout needs to be updated along the minor axis.

    This is implemented to call the layoutColumns method, and then forward to the superclass to actually carry out the layout of the tables rows.

    Overrides:

    layoutMinorAxis in class BoxView

    Parameters:

    targetSpan - the total span given to the view, which would be used to layout the children.

    axis - the axis being layed out.

    offsets - the offsets from the origin of the view for each of the child views. This is a return value and is filled in by the implementation of this method.

    spans - the span of each child view. This is a return value and is filled in by the implementation of this method.

  • calculateMinorAxisRequirements

    protected SizeRequirements calculateMinorAxisRequirements(int axis,
     SizeRequirements r)

    Calculate the requirements for the minor axis. This is called by the superclass whenever the requirements need to be updated (i.e. a preferenceChanged was messaged through this view).

    This is implemented to calculate the requirements as the sum of the requirements of the columns.

    Overrides:

    calculateMinorAxisRequirements in class BoxView

    Parameters:

    axis - the axis being studied

    r - the SizeRequirements object; if null one will be created

    Returns:

    the newly initialized SizeRequirements object

    SizeRequirements

  • getViewAtPosition

    protected View getViewAtPosition(int pos,
     Rectangle a)

    Fetches the child view that represents the given position in the model. This is implemented to walk through the children looking for a range that contains the given position. In this view the children do not necessarily have a one to one mapping with the child elements.

    Overrides:

    getViewAtPosition in class CompositeView

    Parameters:

    pos - the search position >= 0

    a - the allocation to the table on entry, and the allocation of the view containing the position on exit

    Returns:

    the view representing the given position, or null if there isn't one
