Re: [Pharo-users] Question on Morphic drawOn: method.

by Ricardo Moran

Hi Nacho, The red box with two crossing yellow lines indicates that you made a mistake in the drawOn: method. Whenever that happens, here is a tip that might help you. If you can't easily spot your error, you can debug it by evaluating: aBall drawOn: Display getCanvas. This will bring up the debugger and hopefully give you more information.

Re: [Pharo-users] Spotter: How to see more beyond #/##

by Aliaksei Syrel

Hi, Select any of that 5 items and use CMD (Alt on windows,linux)+Shift+Right. Of course shortcuts in spotter are not very obvious, so we are planning to add hints and have all actions to present as buttons in UI Cheers, Alex On Wed, Feb 4, 2015 at 7:11 PM, Sean P.

Question on Morphic drawOn: method.

by nacho

Hi, I have the following question: I want to draw a bouncing ball. First thing I do is create a class: EllipseMorph subclass: #Ball instanceVariableNames: 'position' classVariableNames: '' category: 'PBE-BouncingBall' Then an initialization method that mostly do a super initialize. Then the drawOn: drawOn: aCanvas aCanvas borderWidth:10; borderColor: Color green. And finally a position method: position: aPoint super position: aPoint. position ^ position. Finally in a Playground I do: | aBall | aBall := Ball new. aBall position: ( 10@10 ). aBall openInWorld. But I get a red box with two crossing yellow lines. What I'm missing? Thanks in advance.

You saved me a search. :) > it is not in the dropping/grabbing protocol, but is instead in > events-processing. Maybe it should be moved? This is maybe a broader question (I personally struggle with it quite a bit)... since at least from my naive view it should belong to both (and protocols don't work like tags). Peter

Supply named temporaries to Compiler>>#evaluate:...

by Sean P. DeNigris

I want to be able to evaluate a string like '2 + arg1' and supply anObject for arg1 to the compiler. I naively tried: | aContext | aContext := thisContext copy tempNamed: 'arg1' put: 1; yourself. Compiler evaluate: '2 + arg1' in: aContext to: nil which didn't even come close to working! Any pointers? ----- Cheers, Sean -- View this message in context: http://forum.world.st/Supply-named-temporaries-to-Compiler-evaluate-tp48036… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.
