Features

Implementation

UI8Screen tool uses Smalltalk functionality Smalltalk>>#capture:with: to acquire the remote screen state,

! UI8Screen methodsFor: #ui !
updateUI
	" Private - Update the UI of the receiver. "

	self smalltalk capture: #screen: with: [:data|
		self updateWith: data; updateAfter: rate
	]! !

#capture:with: will try to capture a symbol (#screen) and potentially evaluates a block with the result. This mechanism allows to acquire a resource, an expresion evaluation, or a simple method activation result captured in context of each Smalltalk system.
