Constructor Detail

TableView.TableRow

public TableView.TableRow(Element elem)
Constructs a TableView for the given element.

Parameters:
elem - the element that this view is responsible for
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)

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 whould 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.
Returns:
the offset and span for each child view in the offsets and spans parameters

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 orthoginal 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 whould 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.
Returns:
the offset and span for each child view in the offsets and spans parameters

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
