[Moose-dev] Auto-refreshing Graph Builder hack -- it lives!

Hi all, so I am impatient and I could not wait for Alex’s solution to my question of yesterday. I hacked something together that works most of the time, and now I have my scatterplot that updates itself quite quickly ! :- ) I give the core of the code below, and then report on a problem :-( I have a builder instance variable, and an open and a refresh method. Open opens the first time, and refresh refreshes the view. (I call buildDataset, which builds the right dataset for the graph, that’s not relevant here). open builder := RTGrapher new. builder add: self buildDataset. builder build open refresh | view | view := builder view. view cleanAll. builder := RTGrapher new. builder view: view. builder add: self buildDataset. builder build view signalUpdate. And if you want this animated, just make an infinite loop that calls refresh (with a delay in-between to not hog the CPU). autorefresh self open. [[true] whileTrue: [self refresh. (Delay forMilliseconds: 100) wait]] fork Et voila! C’est cool quoi! (Yes, I’m in France right now :-) ) There is sadly one problem: sometimes I get the red morph of death in the window :-( AthensCairoCanvas>>setShape: sends asAthensShapeOn: to nil. It’s not immediate, but after some time (variable) I always get it :-(. Any pointers on what it may be and how to fix it?? ---> Save our in-boxes! http://emailcharter.org <--- Johan Fabry - http://pleiad.cl/~jfabry PLEIAD lab - Computer Science Department (DCC) - University of Chile
