We have to check because probably the design was violating basic notion of layering. We do not want to have code that totally shortcut morphic.

Re: [Pharo-users] Changing mouse position from Pharo.

Looking at the squeakvm source, there was a primitive for setting the cursor position: InputSensor>> cursorPoint: aPoint "Set aPoint to be the current cursor location." ^self primCursorLocPut: aPoint And InputSensor>>primCursorLocPut: aPoint "If the primitive fails, try again with a rounded point." <primitive: 91> ^ self primCursorLocPutAgain: aPoint rounded Curiosly nowadays the primitive 91 is used for testDisplayDepth, so printing InputSensor default cursorPoint:(100@100) fails (returns self) and InputSensor default cursorPoint:31 or InputSensor default cursorPoint:32 results in false or true Pharo removed the #cursorPoint: selector. 2013/3/15 stephane ducasse <stephane.ducasse(a)free.fr> > > On Mar 15, 2013, at 9:24 AM, phil(a)highoctane.be wrote: > > > Compared to your speed, I am an anemic snail Stef. > > > > Still, I am very interested in that area of which you showed me > > interesting internals. > > > > Curious about the double dispatch you want to do there.

Mohammad What I suggest is the following cycle - write a test -> red - write code until it is green - commit code - drink something save your image all the way go back to step one but with another image :) - take new image - load code - run the tests -> green = good feeling - go back to the beginning Now we cannot do that marvellous cycle but get inspired.
