How to do a "drag'n'drop" (from a file on my computer to a GUI) ?

Hi,

I need to create a drag and drop to put it on the graphic interface of a program created in Matlab but I didn't find out how. The drag and drop must be from a wav file located on my computer to the GUI to be then reused through the program.

Any help would be appreciated :)

Thank you in advance for your answers

Eugy - I don't think that there is a way to drag and drop a file from your workstation onto a open MATLAB GUI. (Though this would be a neat activity.) An alternative is to prompt the user to choose a file. See uigetfile for details.

Eugy: I don't know if that's possible with GUIDE, but I believe GUIDE is too primitive. You might be able to do it with App Designer (GUIDE's replacement) but I haven't had a chance to check it out yet.

Otherwise, if it's even possible, your only chance is Yair http://undocumentedmatlab.com/?s=drag+and+drop. Good luck.

Thank you for you answer

Using the drag'n'drop program found under your link, I could'nt drag in the window the txt file as specidified in the tutorial. I didn't find out the source of the problem (I am a new to GUI), maybe my MatlabVersion (2014) or something with ActiveX.

There were the following instructions:

% Type DragDropTest from the command line to test. Once the figure is % running try dragging a text file into either of 2 areas on the figure. % The upper portion will just populate a listbox with the names of files % that have been dragged into the bar above it. The lower box displays the % contents of any text file dragged into it. The bottom box also allows % text to be dragged from a text editor such as wordpad.

The error I got was:

Error using actxcontrol (line 184) Control creation failed. Invalid ProgID 'RICHTEXT.RichtextCtrl.1'.

Error in DragDropTest (line 36) h1 = actxcontrol(ProgID, [pos(3)*.1 355 pos(3)*.8 20],f,{'OLEDragDrop',@ShowFileNameOnDrop});

Hi Geoff Hayes and Image Analyst, Thank you for your answers :) I went through undocumentedmatlab and I didn't find on it what I was looking for so I used the uigetfile instead of the drag'n'drop, it works fine. Still I keep this website on my Bookmarks, could be a precious help for other tasks !

An even better workaround is to use a list box to load up your data or image files. Why burden the user with the tedious uigetfile()?

For example, see this nice framework called MAGIC

Magic_gui seems interesting, I may certainely get inspired by it, thanks for sharing :)
