Look at the text in a rotated browser first, that's the result you can expect. Basic way would be to instead of rendering the text glyphs rotated, render the glyphs on top of a bitmap of the proper rotated background, then rotate that opaque bitmap instead. Not a perfect solution by any means, but it can be done if you're desperate enough... waiting for VM fixes can take a looooong time :( Cheers, Henry

How about a Start profiling (Stop profiling when clicked) button as well, providing functionality equal to the Start profiling... options from the debug menu? I'd replace it in a heartbeat already tbh, with that extra button, we could reduce it to a single entry for profiling in the debug menu :) Cheers, Henry PS. Anyone know a better naming for "Start drawing again" ? I always wondered how you are supposed to access that if you've stopped drawing, afaik it resets the drawError property of the World (aka. PasteUpMorph) so it starts drawing normally again instead of something crossed out red. It is not done for submorphs, so it's not a convenient way of resetting all drawstates, do we really get drawErrors often enough in the PasteUpMorph itself to warrant this item??

Ahh, with Squeak4.2.3beta1 I get the same as you. Not perfect, but already better. Any idea how the ugly expanded areas can be fixed?

Hmmm, are you running on the latest VM's? With Pharo 1.1 and squeak 4.1, on both OSX and Windows I do not get black rectangles, but "expanded" black areas like attached.

StÃ©phane Ducasse a Ã©crit : > 11296 > ----- > > Issue 2208: Preferences setting > * range setting: bad widget height in the SettingBrowser > * improve TimeProfiler (MorphTreeMorph example) Few words about that: TimeProfiler is a improvement of the current TimeProfileBrowser. just try it: TimeProfiler new openOnBlock: [ 10 timesRepeat: [Transcript show: 'n' asString, String cr]]. or simply TimeProfiler new open and then type-in the code you want to profile. For now, it is in the Morphic-MorphTreeWidget-Examples sys cat, maybe it can replace TimeProfileBrowser in the core. what do you think ? Cheers Alain

Excellent idea. I do not know where is the story about the help system. I would like something extremely simple. Published in the pharo inbox and I will merge it.
