Drag and Drop

Drag and Drop to and from Matlab Figure

Description

Example Drag and Drop in Matlab Figures from Windows Explorer or Other Apps

DrapDropTest creates a simple figure which shows the implementation of dnd using activex.
The microsoft RichtextCtrl.1 activex control is used to demonstrate dnd ability. The control
has several events to which matlab can respond, in particular the OLEDragDrop Event.

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.

This example is not intended to be robust, so please feel free to use it,
but make sure to check over the code in detail to make sure it doesn't
break. I've just coded this quickly to demonstrate the property. Feel
free to email me with questions comments.

• MATLAB release: MATLAB 7.4 (R2007a)
• Other requirements: Works on Windows Platforms

Great example. Now if I could figure out how to make this control invisible and cover an entire figure so you can drag-and-drop to anywhere...

[Lukas Rohr]

ActiveX can't be used on other Operating Systems

[Raphael Austin]

That's a ridiculous reason for a bad rating. If you can find a way to do it without ActiveX, then submit it. I'd love to use it. Be part of the solution.

[Alan Brooks]

Agreed that Lukas's statement should be a comment, not a rating. I would also like to know a cross-platform way of doing it, but have found none to date.

I get the following error. Am I missing an activeX control? If yes, how to get it?

??? Error using ==> feval
Input PROGID does not represent an Activex control.
If this PROGID used to work before, please check vendor's
documentation for equivalent activex control progid.

Error in ==> actxcontrol>createControl at 240
        ctrl = feval(comstr, 'control', position, parent, '', filename, hwnd, licensekey,
        false,parent_string);

Error in ==> actxcontrol at 212
    hControl = createControl;

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

Hi, I tried this but I get an error:
"Error using actxcontrol (line 185)
Control creation failed. Invalid ProgID 'RICHTEXT.RichtextCtrl.1' "

I am using R2011b
