Pharo Smalltalk: Reading from TextMorph

Question

In Smalltalk using Pharo, I'm creating an application that reads the user input and does X.

So far I've managed to make a TextMorph that a user could enter a value into, but I'm unsure of how to read from TextMorphs and then do something with the value.

Any ideas?

Thanks

Well, you can simply send text to your morph and get it's contents. So you could have a button and when button is pressed you do something with contents:

input := TextMorph new.
button :=
   SimpleButtonMorph new
      target: self
      actionSelector: #processTextMorph:;
      arguments: {input};
      yourself.

processTextMorph: aTextMorph
   | contents |
   contents := aTextMorph text.
   "do something with contents"

However maybe you want to use a dialog? Because you can do:

response := UIManager default request: 'What do you want to do?'.
response ifNotNil: [ "do something with the response" ]

And then the execution of UIManager default request: '…' will open a dialog with a text input
