What is the entry point to the application? I could start a BGSCar2012DemoSimulation, and that doesn't allow extra robots. Stephan

Morph: event handler on wrong morph/submorph

by Federico.Balaguer

Hello, I found a problem with BotArena (http://smalltalkhub.com/#!/~FedericoBalaguer/BotArena) on Pharo 4. BotArena is an interactive robot simulation environment that we use in my university to teach OOP basics. BotArena was developed as an instantiation of BOSS (http://smalltalkhub.com/#!/~CAR/BOSS/) BotArena (as well as BOSS) has a window (Morph) that has three buttons and a grid view that is subclass of BorderedMorph. The GridView can handle RedButtons, a click on the grid adds a new robot to the simulation. The problem that raised on Pharo4 is that, after a RedButton event, any event (focus to another pharo window or clicking on one of the buttons of BotArena) will be handled by the GridView. It seems like the GridView retains the focus after the (first) RedButton event was handled. Could someone help me to sort this one out? Thanks!

A script in DrGeo is a first class citizen (i.e. a Smalltalk class) you can use several time on different objects. Therefore, the script instance can hold states with its attributes.

Re: [Pharo-users] Breakpoint ?

by Marcus Denker

Hello, Yes, we are working on it! But as the breakpoints are actually based on a new framework for more general âbehavioural reflectionâ (which needs a bit of deeper changes to the system), this is done in Pharo5. There is no loadable package. What I did is to port the prototype over: there is in the âsuggestionsâ menu an entry to add a breakpoint: This is starting to work, but there are some problems still to be fixed (I am focusing on the reflection framwork now, but soon I will go back to the breakpoints themselves): - Nautilus is confused and thinks it is dirty even though it is not, so you need to accept the method once to see the breakpoint menu - the highlighting is not yet correct - no visualisation in the editor yet - â¦. More work on this will be done soon!
