This makes use of the "ScrollingTable" Panel defined in <a href="ScrollingTable.js">ScrollingTable.js</a>.
|
|
The "AutoRepeatButton" Panel is also defined in that file.
|
|
Each node is resizable.
|
|
</p>
|
|
<p>
|
|
Note how links connect particular port elements on each node.
|
|
When an element has a <a>GraphObject.index</a> less than the <a>Panel.topIndex</a>,
|
|
the panel arranges it be zero sized at the top of the panel.
|
|
Similarly, elements beyond the last item in the panel are arranged to be at the end of the list,
|
|
which may be at the bottom of the panel.
