public abstract class TableView extends BoxView
Implements View interface for a table, that is composed of an element structure where the child elements of the element this view is responsible for represent rows and the child elements of the row elements are cells. The cell elements can have an arbitrary element structure under them, which will be built with the ViewFactory returned by the getViewFactory method.
TABLE ROW CELL CELL ROW CELL CELL
This is implemented as a hierarchy of boxes, the table itself is a vertical box, the rows are horizontal boxes, and the cells are vertical boxes. The cells are allowed to span multiple columns and rows. By default, the table can be thought of as being formed over a grid (i.e. somewhat like one would find in gridbag layout), where table cells can request to span more than one grid cell. The default horizontal span of table cells will be based upon this grid, but can be changed by reimplementing the requested span of the cell (i.e. table cells can have independant spans if desired).
|Modifier and Type||Class and Description|
A table cell can now be any View implementation.
View of a row in a row-centric table.

|Constructor and Description|
Constructs a TableView for the given element.
|Modifier and Type||Method and Description|
Calculate the requirements for the minor axis.
Table cells can now be any arbitrary View implementation and should be produced by the ViewFactory rather than the table.
Creates a new table row.
Forwards the given
Fetches the child view that represents the given position in the model.
Lays out the columns to fit within the given target span.
Perform layout for the minor axis of the box (i.e.
Change the child views.

public TableView(Element elem)
elem- the element that this view is responsible for
protected TableView.TableRow createTableRow(Element elem)
elem- an element
@Deprecated protected TableView.TableCell createTableCell(Element elem)
elem- an element
protected void forwardUpdate(DocumentEvent.ElementChange ec, DocumentEvent e, Shape a, ViewFactory f)
DocumentEventto 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.
ec- changes to the element this view is responsible for (may be
nullif 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
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)
public void replace(int offset, int length, View views)
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)
protected void layoutColumns(int targetSpan, int offsets, int spans, SizeRequirements reqs)
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
protected void layoutMinorAxis(int targetSpan, int axis, int offsets, int spans)
This is implemented to call the
layoutColumns method, and then
forward to the superclass to actually carry out the layout
of the tables rows.
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.
protected SizeRequirements calculateMinorAxisRequirements(int axis, SizeRequirements r)
This is implemented to calculate the requirements as the sum of the requirements of the columns.
axis- the axis being studied
nullone will be created
protected View getViewAtPosition(int pos, Rectangle a)
pos- the search position >= 0
a- the allocation to the table on entry, and the allocation of the view containing the position on exit
nullif there isn't one
