Constructors
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
Methods
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 classBoxView
- 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 benull
to 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 classBoxView
- 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 classBoxView
- 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 classBoxView
- 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 classCompositeView
- 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
