<h1>Network - selection</h1>
|
|
<p>Handles the selection of nodes and edges.</p>
|
|
|
|
<h3>Options</h3>
|
|
<p>The options for the selection have to be contained in an object titled 'selection'.</p>
|
|
<p>Click on the options shown to show how these options are supposed to be used.</p>
|
|
<ul class="nav nav-tabs">
|
|
<li role="presentation" class="active" onclick="hideOptions('fullTab','fullOptions');" id="hiddenTab"><a href="#">options hidden</a></li>
|
|

|
|
selectConnectedEdges: false
|
|
}
|
|
}
|
|
|
|
network.setOptions(options);
|
|
</pre>
|
|
<p>All of the individual options are explained here:</p>
|
|
<table>
|
|
<tr class="header"><td>name</td><td>type</td><td>default</td><td>description</td></tr>
|
|
<tr><td>selectable</td> <td class="mid">Boolean</td><td class="mid"><code>true</code></td><td>When true, the nodes and edges can be selected by the user.</td></tr>
|
|
<tr><td>selectConnectedEdges</td> <td class="mid">Boolean</td><td class="mid"><code>true</code></td><td>When true, on selecting a node, its connecting edges are highlighted.</td></tr>
|
|
</table>
|
|
|
|
<h3>Methods</h3>
|
|
<p>This is a list of all the methods in the public API. Options can be set directly to the module or you can use the setOptions method of the network itself and use the module name as an object name.</p>
|
|
<table>
|
|
<tr class="header"><td class="methodName">name</td><td>returns</td><td>description</td></tr>
|
|
<tr><td>getSelection()</td> <td class="mid">

|
}</pre> </td><td>Returns an object with selected nodes and edges ids.</td></tr>
|
|
|

<tr><td>getSelectedNodes()</td> <td class="mid"><code>[nodeId1, nodeId2, ..]</code></td><td>Returns an array of selected node ids.</td></tr>

|
|
<tr><td>selectNodes(<br> <code><i>Array with nodeIds</i></code>,<br> <code><i>[Boolean highlightEdges]</i></code><br>)</td> <td class="mid">none</td><td>Selects the nodes corresponding to the id's in the input array. If highlightEdges is true or undefined, the neighbouring edges will also be selected. This method unselects all other objects before selecting its own objects. <i>Does not fire events</i>.</td></tr>
|
|
<tr><td>selectEdges(<br> <code><i>Array with edgeIds</i></code><br>)</td> <td class="mid">none</td><td>Selects the edges corresponding to the id's in the input array. This method unselects all other objects before selecting its own objects. <i>Does not fire events</i>.</td></tr>
|
|
<tr><td>unselectAll()</td> <td class="mid">none</td> <td>Unselect all objects. <i>Does not fire events</i>.</td></tr>
|
|
</table>
|
|
|
|
<h3>Events</h3>
|
|
<p>The selection handler does not fire events. All related events are fired by the <a href="./interaction.html">interaction module</a> because they are triggered by user interaction.</p>
