Morphic is a graphical framework in which graphical interface elements can be dynamically composed.
- You can convert an object into a morph and display that morph on the screen by sending it the messages
asMorph openInWorld. - You can manipulate a morph by meta-clicking on it and using the handles that appear. (Handles have help balloons that explain what they do.)
- You can compose morphs by embedding one onto another, either by drag and drop or by sending the message
addMorph:. - You can subclass an existing morph class and redefine key methods, like
initializeanddrawOn:. - You can control how a morph reacts to mouse and keyboard events by redefining the methods
handlesMouseDown:,handlesMouseOver:, etc. - You can animate a morph by defining the methods
step(what to do) andstepTime(the number of milliseconds between steps).
