Class TableView

Implemented Interfaces:
SwingConstants
public abstract class TableView
extends BoxView
A View implementation for rendering tables inside styled text. Tables are rendered as vertical boxes (see BoxView). These boxes have a number of child views, which are the rows of the table. These are horizontal boxes containing the actuall cells of the table. These cells can be arbitrary view implementations and are fetched via the ViewFactory returned by View.getViewFactory().

Nested Class Summary

class
TableView.TableCell
Deprecated. Table cells are now rendered by an arbitrary View implementation.
class
TableView.TableRow
A view implementation that renders a row of a TableView.

Constructor Details

TableView

public TableView(Element el)
Creates a new instance of TableView.
Parameters:
el - the element for which to create a table view

Method Details

calculateMinorAxisRequirements

protected SizeRequirements calculateMinorAxisRequirements(int axis,
                                                          SizeRequirements req)
Calculates the requirements of this view for the minor (== horizontal) axis. This is reimplemented to calculate the requirements as the sum of the size requirements of the columns.
Overrides:
calculateMinorAxisRequirements in interface BoxView
Parameters:
axis - the axis
req - the size requirements object to use, if null a new one will be created

createTableCell

protected TableView.TableCell createTableCell(Element el)

Deprecated. Table cells are now rendered by an arbitrary View implementation.

Creates a view for a table cell. This method is deprecated and not used anymore.
Parameters:
el - the element that represents the table cell
Returns:
a view for rendering the table cell

createTableRow

protected TableView.TableRow createTableRow(Element el)
Creates a view for a table row.
Parameters:
el - the element that represents the table row
Returns:
a view for rendering the table row

forwardUpdate

protected void forwardUpdate(DocumentEvent.ElementChange ec,
                             DocumentEvent e,
                             Shape a,
                             ViewFactory vf)
Overrides:
forwardUpdate in interface BoxView

getViewAtPosition

protected View getViewAtPosition(int pos,
                                 Rectangle a)
Returns the child view that represents the specified position in the model. This is reimplemented because in this view we do not necessarily have a one to one mapping of child elements to child views.
Overrides:
getViewAtPosition in interface CompositeView
Parameters:
pos - the model position for which to query the view
a - the allocation of this view
Returns:
the view that corresponds to the specified model position or null if there is none

layoutColumns

protected void layoutColumns(int targetSpan,
                             int[] offsets,
                             spans[] ,
                             SizeRequirements[] reqs)
Lays out the columns to fit within the specified target span.
Parameters:
targetSpan - the total span for the columns
offsets - an array that holds the offsets of the columns when this method returns
reqs - the size requirements for each column

layoutMinorAxis

protected void layoutMinorAxis(int targetSpan,
                               int axis,
                               int[] offsets,
                               int[] spans)
Lays out the child views along the minor axis of the table (that is the horizontal axis). This is implemented to call layoutColumns(int,int[],spans[],SizeRequirements[]) to layout the column layout of this table, and then forward to the superclass to actually lay out the rows.
Overrides:
layoutMinorAxis in interface BoxView
Parameters:
targetSpan - the available span along the minor (horizontal) axis
axis - the axis
offsets - an array that holds the offsets of the columns when this method returns
spans - an array that holds the spans of the columns when this method returns

replace

public void replace(int offset,
                    int length,
                    View[] views)
Replaces a number of child views with a set of new child views. This is implemented to call the superclass behaviour and invalidate the layout.
Overrides:
replace in interface BoxView
Parameters:
offset - the offset at which to replace child views
length - the number of child views to remove
views - the new set of views
