Hi,

I'd like to a drag and drop a file to put it on the graphic interface of an App created with the Matlab AppDesigner but I didn't find out how. The drag and drop must be from a .mat file located on my computer to an Edit Field (Text) component, in order to be then reused through the program.

Any help would be appreciated :)

Thank you in advance for your answers

is drag and drop necessary? you can use uigetfile as an alternative

Hi,

Thank you for your return.

Yes, I'm aware of uigetfile, which works perfectly. However, drag and drop would be much more convenient and faster.

Have you seen this? It is a file drag and drop for uifigures.

I have used it with some success.

Hi,

Sorry for my late response and thank you for your return.

This is exactly what I was looking for. However, it works with a uifigure, and I'm trying to drag and drop files must be from a .mat file located on my computer to an Edit Field (Text) component of an App.

Do you know how I can proceed?

Thank you in advance,

Regards

在 MATLAB Online 中打开

DragAndDrop.mat

It works for edit fields. I have included a sample .mat file for a test. Here is a quick script I wrote up and assuming you have the DnD_uifigure.m in your path, you will see you can drag files to the edit field and then load the data into field. Hope that helps and you have blessed day!

function TestDragandDrop
EditField = uieditfield(uifigure);
DnD_uifigure(EditField, @(EditField,File)CheckFile(EditField,File));
end

function CheckFile(EditField,File)
% Assuming your mat file has a .mat extension
[Path,FileName,Extension] = fileparts(File.names);
if strcmp(Extension,'.mat')
    
    Data = load(File.names{:},'-mat');
    
    EditField.Value = num2str(Data.Answer);
    
end
end
