How do I detect a key press in the textbox ?

[MMZ39]

Hi,
      I'm looking to develop a simple app such that:
When some text is typed in the textbox , for every keypress Text2Speech engine should kick in and sound the key. When space is pressed it should sound the last word.

For eg if I type "Hello World " I should hear H E L L O Hello W O R L D World .

In the text box events I could not find any event for keypress.

Can this be done. ?

Thanks,
MMZ

there is no such event, but you could use a clock component to check the text of the textbox and if there is a new letter, then do something

see the different text blocks here http://appinventor.mit.edu/explore/ai2/support/blocks/text.html

Another option, although it involves more work is creating your own custom keyboard, using buttons for each allowed character in your app, that way you have full control of each button click, long click, etc.

Yes this should work.  Is there a way to make this custom keyboard pop up when Text box is in focus.

I think no. But you can make your personal keyboard visible if the textbox is visible.

If textbox = visible
Than set "your keyboard" to visible = true

btw. if you use a custom keyboard, you can use a label instead of a textbox...

Yes, Taifun is right. In fact, I think you SHOULD use a label or a button, disguised as a textbox, to detect when it's touched to be able to edit it.
