I have defined a custom DataFlavor, built a Transferrable, and am in the middle of the TransferHandler. Am I right in thinking that you don't need to write any mouse handling code, and just setting the transfer handler for the JComponents is enough? Re: Drag & Drop with custom DataFlavor 12 Years Ago by DavidKroukamp To clarify, you would like to be able to drag a component from one JPanel to another or the smae panel? Also are you looking for DnD option only? Or custom too? Re: Drag & Drop with custom DataFlavor 12 Years Ago by JamesCherrill Hi David, thanks for getting back so quickly. There's a "chooser" area where the user can select and preview different objects, and there's a "work area"(actually a JPanel subclass with custom paintComponent) where those objects can be placed. I want the user to be able to drag the current object from the chooser and drop it … Re: Drag & Drop with custom DataFlavor 12 Years Ago by bguild I've never been able to find a really good guide on the subject of drag and drop, but in my experience it all tends to come together pretty painlessly if you just start by making your Transferable, then a TransferHandler for each of your components that needs one. After that, drag and drop just tends to work the way you'd expect. I always find … Re: Drag & Drop with custom DataFlavor 12 Years Ago by bguild Since you are using custom components, you will probably be needing to call `TransferHandler.exportAsDrag` yourself to get the drag started because JPanel has no `setDragEnabled` method. Instead, you will need to listen for mouse motion to detect the gesture that you want to begin the drag. I imagine you'll want it to start from dragging the mouse … Re: Drag & Drop with custom DataFlavor 12 Years Ago by JamesCherrill David Thanks for that code - I supect its based on an earlier version of Java than 1.6, or maybe it's just a lower-level implementation, because the current version doesn't need the drop target event handler stuff at all, it just needs the TransferHandler to be set for the target JComponent. bguild may be able to shed more light on that?
