Java javax.swing.text Class TableView.TableRow（JDK8）

Constructor Detail

• TableRow

  public TableRow(Element elem)

  Constructs a TableView for the given element.

  Parameters:

  elem - the element that this view is responsible for

  Since:

  1.4

Method Detail

• 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)

• layoutMajorAxis

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

  Perform layout for the major axis of the box (i.e. 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 major axis.

  This is re-implemented to give each child the span of the column width for the table, and to give cells that span multiple columns the multi-column span.

  Overrides:

  layoutMajorAxis 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.

• 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 delegate to the superclass, then adjust the span for any cell that spans multiple 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.

• getResizeWeight

  public int getResizeWeight(int axis)

  Determines the resizability of the view along the given axis. A value of 0 or less is not resizable.

  Overrides:

  getResizeWeight in class BoxView

  Parameters:

  axis - may be either View.X_AXIS or View.Y_AXIS

  Returns:

  the resize weight

  Throws:

  IllegalArgumentException - for an invalid axis

• 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
