<b>GridLayout Properties</b>
<br />
Wrapping Column:
<input type="text" size="3" id="wrappingColumn" value="NaN" onchange="layout()" />
(NaN means there's no limit)
<br />
Wrapping Width:
<input type="text" size="3" id="wrappingWidth" value="NaN" onchange="layout()" />
(NaN means use the diagram's viewport width)
<br />
Cell Size:
<input type="text" size="8" id="cellSize" value="NaN NaN" onchange="layout()" />
(NaN x NaN means use a cell size big enough to hold any node)
<br />
Spacing:
<input type="text" size="8" id="spacing" value="10 10" onchange="layout()" />
(the minimum space between the nodes)
<br />
Alignment:
<input type="radio" name="alignment" onclick="layout()" value="Position" /> Position
<input type="radio" name="alignment" onclick="layout()" value="Location" checked="checked" /> Location
<br />
Arrangement:
<input type="radio" name="arrangement" onclick="layout()" value="LeftToRight" checked="checked" /> LeftToRight
<input type="radio" name="arrangement" onclick="layout()" value="RightToLeft" /> RightToLeft
<br />
Sorting:
<select name="sorting" id="sorting" onchange="layout()">
<option value="Forward" selected="selected">Forward</option>
<option value="Reverse">Reverse</option>
<option value="Ascending">Ascending</option>
<option value="Descending">Descending</option>
