![]() In code, what’s going on is that the Trash view implements the DropTarget interface. Since it is a trash icon, you know that it means the icon being dragged will be removed from the workspace. The red color gives you a good indication that something will happen if you drop the icon there. If you drag an icon over that icon, you will see a change in the color of the view being dragged. You should see that a Trash icon appears. In the Launcher, when you start dragging an icon, check out what happens at the bottom of the screen. Here’s how DropTargets figure into the Android Launcher. The one object I did not explore fully was the DropTarget. The Launcher object model includes objects like DragLayer, DragSource, DragController, and DropTarget. In an earlier note (see “ Moving Views In Android – Part 2“), I had written up how the Android Launcher app supports moveable views using the touch interface. The classes in this app are derived from the Android Launcher application. The other two show the background color changes in the drop zones as you move over them. Figure 2 shows the menu where you can add other objects and enable and disable the orange drop zone. There are two red drop zones and one orange drop zone. Figure 1 is what it looks like when it launches. The figures show what the app looks like at various points. As you drag views around the screen, the drop zones light up to indicate that they are places where you can drop objects. In my example, I called those areas DropZones. I also worked out how you can have different drop behavior for different areas of the screen. I now understand how views can be placed on the screen and moved by touching them. His response took a couple of days, but was very helpful.I have come to the end of my work on drag-drop in Android. I contacted the developer during the process of using the graphical features he's added. I've now added this app to my list of indispensable utilities. Once I figured out Dropzone could help me out, I had my first action done in 10 minutes. I tried to do it with Apple's Automator which kept me running in circles. In no way is this app isn't going to replace the need for full-featured development on the Mac, but if all you want to do is something like "adding custom timestamps to a filename", it's hard to beat Dropzone. Intuitive interface (at least, when compared to using Python by itself) While I don't need this app to create and use Python scripts, life is just easier with it. This app lets you easily create custom drop actions using Python or Ruby. What a great app! I'd purchased this as part of a bundle and thought it was another dock or dragstrip. So you can help us make Dropzone even better! Not only that, but all the code for the destinations above is open source. Extend Dropzone - Dropzone has a powerful Ruby based API that allows you to script Dropzone to do whatever you need.Zip and Email - The Zip & Email destination zips up the dragged files and adds them as a Mail attachment, all ready to send.Underneath, Dropzone uses the fast and powerful Rsync file transfer tool to do its work. Dropzone lets you setup destinations that do this. Copy or Move Files - Sometimes you want to copy or move a file or folder somewhere else on your Mac.Great for storing those little snippets of text that you don't want to lose. Save Text - Drop some text onto the Save Text destination, Dropzone asks you for a name, and saves it for you.If you hold down option while dragging, Dropzone will even zip up the files or folders for you before uploading and put the URL on the clipboard. FTP Upload - You can setup as many FTP servers as you like with Dropzone.It can even copy the direct image URL to the clipboard so you can paste it to a friend. Flickr Upload - Drop a bunch of pictures on to the Flickr Upload destination and Dropzone uploads them for you.Install Applications - Drag a DMG onto the Install Application destination, and Dropzone mounts the disk image, finds the application inside, copies it to your applications folder, launches it, ejects the disk image and moves it to the trash for you.Simply add it to your Dropzone grid, and then you can launch the app by clicking on it in Dropzones grid, or you can drag files or folders onto it. Launch Applications - Sometimes you want to keep an application quickly available, but you don't want it taking up space in your Dock.Whether you're installing an app, uploading a file to an FTP server or sharing your photos on Flickr. Drop the file onto a destination and Dropzone will take care of the rest. Drag a file onto the dock icon and your fully customizable grid of destinations flies smoothly out using core animation. Dropzone makes it faster and easier to get things done.
