App Inventor introduces copy and paste of code blocks!

App Inventor has introduced “copy and paste” of code blocks. Now you can copy blocks of code within a current screen, or from one screen to another screen, or even between projects. This is great news!

Look for the “backpack” icon at upper right of the blocks Viewer screen:

AI_Copy1

Select a block or blocks with the mouse pointer, and then click and drag the selected blocks into the backpack. A copy of the blocks are placed into the backpack and your original blocks also remain in the editing window.

Click on the backpack icon and it displays the code blocks currently stored in the backpack:

AI_Copy2

Click on the code block in the backpack (at right) and drag it into the Blocks Viewer. That is all you need to do to copy blocks.

Use this feature to copy blocks within your current screen, or to copy blocks from one screen to another screen, or to copy blocks from one app to another app.

You can put several blocks into the backpack, and then select only the ones you wish to copy over to another blocks Viewer.

How do you empty the backpack? It seems the only way to empty the backpack of saved items is to close the editing windows, go back to the MIT App Inventor home page (http://appinventor.mit.edu/) and select the Create apps! button to re-enter the designer and blocks editor.

Regardless, this is a GREAT NEW FEATURE! Thanks MIT App Inventor team!

Is there a good way to print App Inventor blocks code?

I do not think there is any good way to make print outs of the App Inventor blocks code.

What I do is:

In Windows 7 (also works in Vista and newer version) is to use the Snipping Tool to select a section of blocks code on screen, copy the selection, and then paste that into a Word document. I make several “snips” as needed, to capture all of the code, and paste each into the document. Then I print out the document.

Is there a better way? I do not know but if you have a better solution, let us know in the comments! Thanks!

MIT App Inventor makes many things easier – but eventually one must learn to think like a software developer and become familiar with concepts like data structures, algorithms, design patterns, and software engineering design and project management.
