Drag node instead of draw link when click n' drag (Read 4967 times)

	Hi, I'm wondering if there is a way to achieve this: when you click and drag a node that is unselected, it should move instead of starting to draw a link. I've proved with setShapeHandlesStyle (EasyMove, MoveOnly, etc.) and always it starts to draw a link from the node I'm dragging. Anyone knows how can I do that? Best regards. Cristian.

	The MoveOnly flag should not allow link drawing. If you want to be able to move the nodes without first selecting them, try this: Code diagramView.setModificationStart(ModificationStart.AutoHandles); I hope it helps. Regards, Meppy

	Ok, I understand... But it still not working... I'm using an Applet inside a JSP and a Diagram object as a session Bean. So, in the "AppletStarted" event of the applet I'm doing: Code var d = applet.getDiagramView().setModificationStart(applet.getScriptHelper().getConstant('ModificationStart', 'AutoHandles')); But when I click and drag an unselected node It starts drawing a link instead of moving that node. Should I use or set in adition any Diagram property? (like shapeHandlesStyle) Cristian.

	DiagramView.ModificationStart simply enables node interactions without the need to select the node first. The allowed interactions still depend on the value of the node's HandlesStyle. Therefore, you need to set HandlesStyle to a value, which prevents link creation, such as MoveOnly. Code node.setHandlesStyle(7); // MoveOnly This however will prevent link creation even if the node is selected, which might not be desired. Regards, Meppy

	Go it... I think I found the problem... The javascript function asociated to the AppletStarted param of the appplet is never called. This is how my applet is defined in the JSP page: Code <applet id="diag" archive="../JDiagram.jar" width='${diagram.getBounds().getWidth()}>' height='${ diagram.getBounds().getHeight()}>' code="com.mindfusion.diagramming.DiagramApplet" mayscript> <param name='DiagramData' value='........'> <param name='Clicked' value='docClicked'> <param name='LinkDoubleClicked' value='linkDoubleClicked'> <param name='AppletStarted' value='appletStarted'> </applet> I wasn't able to find info about the "params" of the applet.... in particular, the "AppletStarted" or "DiagramData" params. Where it is supposed that I can find that info? Regards, Cristian

	Define the appletStarted function with two arguments. I am not entirely sure what they are for (they come as undefined in my tests). The other event handlers need to have the corresponding number of arguments too, as described here. Regards, Meppy
