Hi Doru, all
I am having a problem with the Mondrian panel in AspectMaps using an updateOn:from:. (See
code below for details of the glamour script) I saw that on each update the update
progressively gets slower. About double the time to be exact. I added some debugging code
to the visualization to check this and ... on each update the mondrian drawing is painted
double the amount of time than before: 1, 2, 4, 8, ... Poking around in the debugger shows
the old pane is indeed not removed from the subscriptions list leading to doubling the
amount of panes in the list on each refresh.
I suppose there is a simple fix for this so if you could fix it I would very much
appreciate it! :-)
mondrianPaneOn: browser
|num|
num :=0.
browser transmit to: #mpanel; from: #models; andShow: [:a |
a mondrian
painting: [:view :model |
Transcript show: '+'.
model isNil ifFalse: [ <DO THE PAINTING>]].
Transcript show: num; cr. num := num + 1];
updateOn: AMModelChanged from: [:ent | self announcer ];
allowNil ].
