Get Info of Components

A. Blocks

You can get the information of your blocks in two different ways.

1. Built-in and Component blocks

Go to the Designer window and hover the block you want to get the description from. Screenshot from Taifun (top left). This works for all blocks.

2. Component blocks

If you want to get information of a component block, you can:

a. Search the block's component category on Google. For example, if you want to know how to use set Button1. Image, search on Google 'user interface app inventor'.

b. Click on the top result. The colored link should say 'User Interface - MIT App Inventor 2' for our button.

c. You see a table of contents of all of the components in the same category. Click on the component of the block you want to view from 'for example, I click on Button'.

d. I see a description of the component. 

e. Find your block. For example, my block is an property. So, I find Event, then I see Image. It gave me a description of the block (blue)and what should be attached to the block/what it returns (orange) (some purple blocks or yellow blocks don't have those).

Some blocks are only available in the Designer or Blocks, so they have labels like blocks-only or designer-only. My block is available in both, so there is no need for labels.
