Adding a title to uiimage

I am working with matlab app designer, matlab 2020b

essentially I want to have several dragable objects that look like pipe sections, connect and reconnect them, and change their sizes. each section should have a label.

So far I have worked with several UIbutton objects, dragging them around. However, I encountered two problems that i couldnt solve.

1. UIbuttons have these annoying borders that cannot be cancelled, and

2. the pictures cannot be streched properly according to my needs.the attached picture demonstrates this nicely- at the bottom you can see a UIbutton. when you try to strech it the picture behaves in a very annoying fashion. at the top tou have a UIimage, that streches correctly when you change its dimensions.

so i decided to use UIimages instead. my problem now is how to insert the label properly. images don't seem to have any option for adding a label or a title.

would be thankful for any assistance.

Hi Nathan,

Regarding the resizing images and UIImage component, it has a property called ScaleMethod, check it, maybe that will solve your issue.

You can create label and adjust its Position property through events and listeners. Maybe you can change the label positions at the end of the drag and drop callback? Unfortunately I can't help with this as I've never worked with them.

Thank you for your answer mario. the scale method can be slected for a UIimage but not for a UIbutton. a label is available for a UIbutton but not for a UIimage. that is my issue.

your second suggestion is feasible I think, but it's a shame if we have to resort to this. the purpose of the app designer is to enable us to do this kind of things

That's true, but button is not really ment to behave like that.

If you're adventurous, you can also create your own component, there are more sites that you can find information about it, here's one https://www.mathworks.com/help/matlab/creating_guis/add-ui-components-to-app-designer-programmatically.html.

Maybe someone else might have a better idea.

thank you again Mario. the site you linked to doesn't containt a lot of information. it shows how to create your own button programticaly but not how to create a custom component different from a button. would be thankful for any additional information.

That's true, well, here's the link you need. It's available from R2020b
