tsd-typography"> <p>The DraggingTool is used to move or copy selected parts with the mouse. This sets the <a href="Part.html#location">Part.location</a> property; you may want to save the location to the model by using a TwoWay <a href="Binding.html">Binding</a> on the "location" property in your Parts/Nodes/Groups templates.</p> <p>Dragging the selection moves parts for which <a href="Part.html#canMove">Part.canMove</a> is true. If the user holds down the Control key (Option key on Mac), this tool will make a copy of the parts being dragged, for those parts for which <a href="Part.html#canCopy">Part.canCopy</a> is true.</p> <p>When the drag starts it calls <a href="DraggingTool.html#computeEffectiveCollection">computeEffectiveCollection</a> to find the actual collection of <a href="Part.html">Part</a>s to be dragged. Normally this collection includes not only the <a href="Diagram.html#selection">Diagram.selection</a>, but also parts that belong to those selected parts, such as members of groups. If <a href="DraggingTool.html#dragsTree">dragsTree</a> is true, the effective collection also includes all of the nodes and links that constitute the subtree starting from selected nodes. The result of <a href="DraggingTool.html#computeEffectiveCollection">computeEffectiveCollection</a> is not a <a href="Set.html">Set</a> but a <a href="Map.html">Map</a> which remembers the original <a href="Part.html#location">Part.location</a> for all of the dragged parts. This map is saved as the value of <a href="DraggingTool.html#draggedParts">draggedParts</a>.</p> <p>During the drag if the user holds down the Control/Option key this tool makes a copy of the <a href="DraggingTool.html#draggedParts">draggedParts</a> and proceeds to drag it around. (It only copies the <a href="Diagram.html#selection">Diagram.selection</a>, not the whole effective collection, if <a href="DraggingTool.html#copiesEffectiveCollection">copiesEffectiveCollection</a> is false.) The collection of copied parts is held by <a href="DraggingTool.html#copiedParts">copiedParts</a>. It too is a <a href="Map.html">Map</a> remembering the original locations of the parts. <a href="DraggingTool.html#copiedParts">copiedParts</a> will be null when this tool is moving (not copying) at the moment.</p> <p>Each Part's movement is limited by the <a href="Diagram.html#computeMove">Diagram.computeMove</a> method. By default it limits the <a href="Part.html#location">Part.location</a> to be within the bounds given by <a href="Part.html#minLocation">Part.minLocation</a> and <a href="Part.html#maxLocation">Part.maxLocation</a>. (Those default to minus Infinity to plus Infinity.) As a further convenience, the value of NaN in minLocation and maxLocation cause <a href="Diagram.html#computeMove">Diagram.computeMove</a> to use the part's current location. So, for example, an easy way to declare that the user may only drag a node horizontally is to just set:</p> <pre><code class="language-js"><span style="color: #DCDCAA">$</span><span style="color: #D4D4D4">(</span><span style="color: #9CDCFE">go</span><span style="color: #D4D4D4">.</span><span style="color: #9CDCFE">Node</span><span style="color: #D4D4D4">,</span> <span style="color: #D4D4D4"> . . .</span> <span style="color: #D4D4D4"> { </span><span style="color: #9CDCFE">minLocation:</span><span style="color: #D4D4D4"> </span><span style="color: #569CD6">new</span><span style="color: #D4D4D4"> </span><span style="color: #9CDCFE">go</span><span style="color: #D4D4D4">.</span><span style="color: #DCDCAA">Point</span><span style="color: #D4D4D4">(-</span><span style="color: #569CD6">Infinity</span><span style="color: #D4D4D4">, </span><span style="color: #569CD6">NaN</span><span style="color: #D4D4D4">), </span><span style="color: #9CDCFE">maxLocation:</span><span style="color: #D4D4D4"> </span><span style="color: #569CD6">new</span><span style="color: #D4D4D4"> </span><span style="color: #9CDCFE">go</span><span style="color: #D4D4D4">.</span><span style="color: #DCDCAA">Point</span><span style="color: #D4D4D4">(</span><span style="color: #569CD6">Infinity</span><span style="color: #D4D4D4">, </span><span style="color: #569CD6">NaN</span><span style="color: #D4D4D4">) },</span> <span style="color: #D4D4D4"> . . .</span> <span style="color: #D4D4D4">)</span> </code></pre> <p>If you set <a href="DraggingTool.html#isGridSnapEnabled">isGridSnapEnabled</a> to true, dragged or copied parts will be snapped to points on a grid. The snapping occurs continuously during a drag unless you set <a href="DraggingTool.html#isGridSnapRealtime">isGridSnapRealtime</a> to false. Normally the grid points come from the <a href="Diagram.html#grid">Diagram.grid</a>, even if that grid is not <a href="GraphObject.html#visible">GraphObject.visible</a>. However you can override those grid's properties for the snapping grid cell size and offset by setting the properties here: <a href="DraggingTool.html#gridSnapCellSize">gridSnapCellSize</a> and <a href="DraggingTool.html#gridSnapOrigin">gridSnapOrigin</a>. This computes the point to snap to for each dragged part. The resulting point is used as the new <a href="Part.html#location">Part.location</a>.</p> <p>For the most general control over where a part may be dragged, either set the <a href="Part.html#dragComputation">Part.dragComputation</a> property or override <a href="Diagram.html#computeMove">Diagram.computeMove</a>. For the common case of wanting to keep member nodes within the <a href="Group.html">Group</a> that they are members of, you can do something like:</p> <pre><code class="language-js"><span
