I trap Button-2 drag events and transform them to (ctrl+up/down arrow) events, which is what Pharo processes as mousewheel. Scrolling by Button-2 drag is what applications like Acrobat reader or Firefox do as well. And Thinkpad Laptops offer a system wide setting to do this with all the scrollable Windows. Unfortunately they do it on a system level without sending events to the application, so it does not work with Morphic. Cheers, Chris

Yeap looks excellent! I was thinking that some part of the pharo by example could be turned into pages.

Thanks We should definitively invest in this part of the infrastructure. I wanted to know on your machine the mouse wheel does not work because on mac in the latest version I can use it.

Re: [Pharo-project] Help system now for Squeak and Pharo

Hi Torsten, Thanks for the contribution! I like it. It is simple to use and new books/pages can be added by external packages. We should consider adding it to the default Pharo configuration and encourage package maintainers to create help pages for their software.

Hello, See comment on MouseWheelEvent class - thats why I thought mapping to (ctrl+up/down arrow) is the pharo way to do it. Also that's what I can see coming in (examining InputEventFetcher) on WinXP when I use a mousewheel. I think MouseWheel is not cross platform compatible.

( Described in comment on InputEventFetcher ). That is why I thought, there could be a place to make such things configurable on a higher level (dealing with event objects rather than raw data). Btw. I got confused with the Button colours: Comments should refer to blue Button not yellow.

Re: [Pharo-project] Substrings for strings?

the meta approach did you try the methodfinder? open method finder type 'Foo Bar Baz' . 5 . 3 -> no single function 'Foo Bar Baz' . $B .
