Hello,
I would like to create an app in the Appdesigner with multiple buttons (i.e. contacts). Upon clicking one of the buttons, the contact's name and address should appear. For this, I would like to add a small envelope icon in front of the adress.
The address itself is in a TextArea. I have tried
env = app.Image
env.ImageSource = 'envelope.png'
line1 = [env, 'address'].
The error I get is:
'Conversion to matlab.ui.control.Image from char is not possible.'
Would anyone have any advice?
Thanks is advance!

Might just be a workaround, but have you tried using the envelope-emoji instead of including a PNG image?

Thanks, but not actually trying to use envelope, just using this as an example...

Hi,
From my understanding, you want to have an 'image' near your 'textarea' such that they are aligned. A possible workaround for this would be to have the image and textarea, both defined in the same figure handle. You can then position them accordingly, so that they are aligned. For example, to have the image to the right of text area, you can use the following code.
fig = uifigure;
im = uiimage(fig);
im.ImageSource = 'envelope.png';
txa = uitextarea(fig);
txa.Value='Address';
im.Position(1)=txa.Position(1)+txa.Position(3);
Alternatively, you can group together the text area and Image in the Design View,to modify them as a single unit, by using the Grouping Tool present in the Arrange Section of the toolstrip.
