<div id=Content><div class="CClass"><div class=CTopic id=MainTopic><h1 class=CTitle><a name="mxConnectionHandler"></a>mxConnectionHandler</h1><div class=CBody><p>Graph event handler that creates new connections. Uses <mxTerminalMarker> for finding and highlighting the source and target vertices and <a href="#mxConnectionHandler.factoryMethod" class=LVariable id=link101 onMouseOver="ShowTip(event, 'tt5', 'link101')" onMouseOut="HideTip('tt5')">factoryMethod</a> to create the edge instance. This handler is built-into <mxGraph.connectionHandler> and enabled using <a href="../view/mxGraph-js.html#mxGraph.setConnectable" class=LFunction id=link102 onMouseOver="ShowTip(event, 'tt82', 'link102')" onMouseOut="HideTip('tt82')">mxGraph.setConnectable</a>.</p><h4 class=CHeading>Example</h4><blockquote><pre class="prettyprint">new mxConnectionHandler(graph, function(source, target, style)
|
|
{
|
|
edge = new mxCell('', new mxGeometry());
|
|
edge.setEdge(true);
|
|
edge.setStyle(style);
|
|
edge.geometry.relative = true;
|
|
return edge;
|
|
});</pre></blockquote><p>Here is an alternative solution that just sets a specific user object for new edges by overriding <a href="#mxConnectionHandler.insertEdge" class=LFunction id=link103 onMouseOver="ShowTip(event, 'tt78', 'link103')" onMouseOut="HideTip('tt78')">insertEdge</a>.</p><blockquote><pre class="prettyprint">mxConnectionHandlerInsertEdge = mxConnectionHandler.prototype.insertEdge;
|
|
mxConnectionHandler.prototype.insertEdge = function(parent, id, value, source, target, style)
|
|
{
|
|
value = 'Test';
|
|
|
|
return mxConnectionHandlerInsertEdge.apply(this, arguments);
|
|
};</pre></blockquote><h4 class=CHeading>Using images to trigger connections</h4><p>This handler uses mxTerminalMarker to find the source and target cell for the new connection and creates a new edge using <a href="#mxConnectionHandler.connect" class=LFunction id=link104 onMouseOver="ShowTip(event, 'tt1', 'link104')" onMouseOut="HideTip('tt1')">connect</a>. The new edge is created using <a href="#mxConnectionHandler.createEdge" class=LFunction id=link105 onMouseOver="ShowTip(event, 'tt80', 'link105')" onMouseOut="HideTip('tt80')">createEdge</a> which in turn uses <a href="#mxConnectionHandler.factoryMethod" class=LVariable id=link106 onMouseOver="ShowTip(event, 'tt5', 'link106')" onMouseOut="HideTip('tt5')">factoryMethod</a> or creates a new default edge.</p><p>The handler uses a “highlight-paradigm” for indicating if a cell is being used as a source or target terminal, as seen in MS Visio and other products. In order to allow both, moving and connecting cells at the same time, <a href="../util/mxConstants-js.html#mxConstants.DEFAULT_HOTSPOT" class=LVariable id=link107 onMouseOver="ShowTip(event, 'tt83', 'link107')" onMouseOut="HideTip('tt83')">mxConstants.DEFAULT_HOTSPOT</a> is used in the handler to determine the hotspot of a cell, that is, the region of the cell which is used to trigger a new connection. The constant is a value between 0 and 1 that specifies the amount of the width and height around the center to be used for the hotspot of a cell and its default value is 0.5. In addition, <a href="../util/mxConstants-js.html#mxConstants.MIN_HOTSPOT_SIZE" class=LVariable id=link108 onMouseOver="ShowTip(event, 'tt84', 'link108')" onMouseOut="HideTip('tt84')">mxConstants.MIN_HOTSPOT_SIZE</a> defines the minimum number of pixels for the width and height of the hotspot.</p><p>This solution, while standards compliant, may be somewhat confusing because there is no visual indicator for the hotspot and the highlight is seen to switch on and off while the mouse is being moved in and out. Furthermore, this paradigm does not allow to create different connections depending on the highlighted hotspot as there is only one hotspot per cell and it normally does not allow cells to be moved and connected at the same time as there is no clear indication of the connectable area of the cell.</p><p>To come across these issues, the handle has an additional <a href="#mxConnectionHandler.createIcons" class=LFunction id=link109 onMouseOver="ShowTip(event, 'tt54', 'link109')" onMouseOut="HideTip('tt54')">createIcons</a> hook with a default implementation that allows to create one icon to be used to trigger new connections. If this icon is specified, then new connections can only be created if the image is clicked while the cell is being highlighted. The <a href="#mxConnectionHandler.createIcons" class=LFunction id=link110 onMouseOver="ShowTip(event, 'tt54', 'link110')" onMouseOut="HideTip('tt54')">createIcons</a> hook may be overridden to create more than one <a href="../shape/mxImageShape-js.html#mxImageShape" class=LClass id=link111 onMouseOver="ShowTip(event, 'tt55', 'link111')" onMouseOut="HideTip('tt55')">mxImageShape</a> for creating new connections, but the default implementation supports one image and is used as follows:</p><p>In order to display the “connect image” whenever the mouse is over the cell, an DEFAULT_HOTSPOT of 1 should be used:</p><blockquote><pre class="prettyprint">mxConstants.DEFAULT_HOTSPOT = 1;</pre></blockquote><p>In order to avoid confusion with the highlighting, the highlight color should not be used with a connect image:</p><blockquote><pre class="prettyprint">mxConstants.HIGHLIGHT_COLOR = null;</pre></blockquote><p>To install the image, the connectImage field of the mxConnectionHandler must be assigned a new <a href="../util/mxImage-js.html#mxImage" class=LClass id=link112 onMouseOver="ShowTip(event, 'tt9', 'link112')" onMouseOut="HideTip('tt9')">mxImage</a> instance:</p><blockquote><pre class="prettyprint">mxConnectionHandler.prototype.connectImage = new mxImage('images/green-dot.gif', 14, 14);</pre></blockquote><p>This will use the green-dot.gif with a width and height of 14 pixels as the image to trigger new connections. In createIcons the icon field of the handler will be set in order to remember the icon that has been clicked for creating the new connection. This field will be available under selectedIcon in the connect method, which may be overridden to take the icon that triggered the new connection into account. This is useful if more than one icon may be used to create a connection.</p><!--START_ND_SUMMARY--><div class=Summary><div class=STitle>Summary</div><div class=SBorder><table border=0 cellspacing=0
