Re: [Pharo-project] [newbies] How can I diagnose kinetic scrolling screen flicker?

Don't know how to solve your smooth zooming problem, but have a look at Dr Geo: zooming is very smooth there! - Francisco On 1 May 2012, at 12:24, Martin Drautzburg <Martin.Drautzburg(a)web.de> wrote: > Hello all, > > in my (first) pharo programm, I have a pane with apx 100 Morphs.

[Pharo-project] [newbies] How can I diagnose kinetic scrolling screen flicker?

by Martin Drautzburg

Hello all, in my (first) pharo programm, I have a pane with apx 100 Morphs. The pane can be zoomed and scrolled both vertically and horizontally. The horizontal scrolling means scrolling time and is self-written. I implemented some sort of kinetic scrolling using the mouse wheel, where a scroll destination is set and in a step method I halve the distance to the destination with each step. This looks kind of nice, but not nice enough. Scrolling is not as smooth as I had hoped. Sometimes there is a delay between the wheel move and the display actually showing some motion. Also I have the impression, that not all parts of the pane are redrawn at the same time. Morphs which are exactly below each other, appear minimally skewed during the scroll. Strange enough the zooming, which has to do about the same underlying geometry calculations is a lot more snappy (but not kinetic). Likewise the vertical scrolling which used a StandardScrollPane appears more snappy. I looks like using a stepper is the root of the problem. I just could not figure out where the time goes. I put a MessageTally into the step method, only to find out, that doing 1000 steps takes less than a second. So the problem must be elsewehere. Any ideas would be much appreciated. -- Martin

And it will return what it finds at the position. In the case of simple slots, there is a 1:1 mapping to iVars and therefore no change. See section 4.1 Primitive Slots "Primitive slots are metaobjects that simply bind an instance variable to a field index." Marcus -- Marcus Denker -- http://marcusdenker.de

Re: [Pharo-project] Questionn

Thanks Camilo - I've tried your image with the latest CogVM for Mac and it's usable. I understand this is work in progress, are you planning to change Object>>instVarAt: with a new primitive? or will that be handled on the image side? Apart from the change in the class declaration, do you think that any of the existing code will have to be changed? What's the biggest advantage of having slots? (and will we also have slots for temp vars?)
