Multiplicar botão clicado (Multiply button clicked)


Is it possible to create a function that, when I click on a certain BUTTON (EX: BtnFrente), the program makes a copy of the button clicked,
So I can, click and drag the created btn?

As the attached image

Outside chance that you can do it with a webviewer and html or Java Script.

In AI, you cannot set the left and top properties of a component...  But you could possibly do it with HTML...

Probably would be pretty difficult.

Referente aos botoes serem copiados não encontrei nada na net, e também no app inventor.

Saberia dizer como eu faria pra armazenar a informação que determinado Botão x foi clicado, e acionar esse botãox somente depois que o botao Y for clicado ?

you can't create components dynamically in App Inventor
but you could use the canvas and image sprites as buttons
just set the image sprites to visible = false you do not need currently and set them to visible = true as soon as you need them
also you can click and drag image sprites around...

Sounds similar to my > frogs-n-flies < game.
The aia and apk are there to see how it works.
But basically it is as Taifun said.
Create ImageSprites ahead of time and hide them.
Then make them Visible as you need them.

Taison, thank you for your reply, I confess I had not thought of that, because it is beginner with AppInventor. 

Scott, Looking at the picture, is just that. 
The difference is that when you press the "GO" button will send a bluetooth command to an Arduino. 
Can contact on my email?

Hi All,
I am new for App Inventor.
I am using App Inventor 2 on Mac with Chorme.
1) I have list to be displayed in table with checkboxes for every element.
I am trying to dynamically create table with list elements and checkbox . Can I do this using App Inventor ?
I saw one example which embeds HTML but without integrating HTML can we achieve it ?
2) Also is there any way to copy user components ? i.e. buttons , labels ?

no

you can prepare as many elements as you think you might need and hide them, then if you need them, set visible = true
2) Also is there any way to copy user components ? i.e. buttons , labels ?
to copy something in the blocks editor, just use ctrl-c and ctrl-v
but you can't copy definitions in the designer

--
So say I have list of 200 items and want to render them, which selectable check boxes:
1) I'll need to define table with all components
2) I'll not able to render them dynamically

OR
 If I have list picker and to add selected items in table, I'll need to create those many elements first ?
