Hello all.

Today I launched power apps for the first time. I have always preferred to learn from a living organism. I decided to start with something simple: I have two objects, the first is a button called "button1", the second is a square called "test". I would like the rectangle to show or hide after pressing the button. I watched some tips on YT, looked for google but I don't know how to do it. Before, I had a little fun with VBA, but I can see that it is completely different here.

Write this code in the relative properties:

Button's OnClick property;

UpdateContext({varShow:!varShow});

Rectangle's Visible Property;

varShow

UpdateContext set up the variable in the context of the screen.

By default they are boolean and value is false.

If you write:

UpdateContext({varShow:!varShow});

Then you are toggling the Boolean value of variable name varShow. When you set this variable in the visible property of another control. You are manipulating that control's visibility based on variable Boolean value.

one more question, so as not to pose a new topic:
I launched the applications based on the canvas, I had a choice of a phone or tablet. What if I wanted to create an application that works in a browser on a desktop computer?

It will work in both cases. But tablet is better choice since it will be large screen in browser compare to phone

yes, but is it generally possible to choose what area (size) of the screen I can have, or do I only have these two options?

Once you choose that and create app you can change the layout and screensize from inside the app in settings options
