  • Constructor Details

    • 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 Details

    • 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
