Recipe: How to use an IconicButton in Morphic
Last updated at 5:28 am UTC on 25 June 2018
You would like to have an icon in your Morphic world which activates the evaluation of a block of code when clicked.
You might want to use an IconicButton. If the action you want to perform is relatively simple, you don't even have to override anything.
target := "do something when button is clicked" [Transcript show: 'Button Pressed!'; cr].
i := IconicButton new.
"i labelGraphic: aForm."
i target: target.
i actionSelector: #value.
Then select the above text, (Cmd D) DoIt and you'll get a new button. Press the button and the Transcript should print the message.
The "target" in the above will be evaluated when you click on the button. You can pass any number of arguments to the target as well.
