Help With Italo's Color Picker

[Jon_Stier]

So I got Italo’s color picker into my drawing app and got it to work with my Drawing screen via a TinyDB. But when I go from the ColorPicker screen back to the drawing screen, obviously the screen is initialized anew and the previous things drawn are not there anymore. Is there a way to save the elements that are drawn before switching to the ColorPicker screen and redraw them upon reopening of the Drawing screen?

By the way, this is the structure of my drawing blocks.

Don’t use different screens, use arrangements and their visibility to switch between them on one screen, that way everything happens on the same screen and you do not lose your drawing

What do you mean by arrangements?

Use different screens wisely

• Before starting to create another screen, first you should think about is it really necessary? 
• See also Building apps with many screens and SteveJG's post about advantages/disadvantages, because in only one screen you also can use vertical arrangements to simulate different screens, just set the arrangements to visible = true/false as needed... 
• See also Martyn_HK's example about how to use Tabs in App Inventor and another example from Cyd. and my Tabbed Screens Demo

If you decided to use different screens, then you should switch them correctly, else you will run out of memory after a while...
