[Pharo-project] simulating Mousewheel

by Ch Lamprecht

Running Pharo on an IBM Thinkpad with a trackpoint input device, I was a bit disappointed, that the autoscroll feature does not work in Pharo (pressing Button-2 and moving the mouse pointer should scroll the window below the mouse pointer). I took it as an exercise and the attached code does what I want, but it does not feel right (like not at the the right 'level'): Is there a place in the Morph hierarchy where such behavior changes could be plugged in? Or did I overlook a preference setting ;) ? Cheers, Chris Object subclass: #InputEventFetcher instanceVariableNames: 'eventHandlers fetcherProcess inputSemaphore mousewheel ycoord' classVariableNames: 'Default' poolDictionaries: 'EventSensorConstants' category: 'Kernel-Processes' InputEventFetcher>> signalEvent: eventBuffer "Signal the event buffer to all registered event handlers.

[Pharo-project] Substrings for strings?

I can't find any method that allows me to take a substring out of a string my location and length. Anyone know?

Maybe for easy loading we should reaint the TheWorldMenu class for now? Registering to the new world menu uses (as people might have guessed): Evil Pragmas :-) MenuRegistrationExample has an example: myOwnCoolToolRegistrationOn: aBuilder <worldMenuExample> (aBuilder item: #MyOwnCoolTool) parent: #Tools; label: 'My own cool tool'; target: Workspace; selector: #openContents: ; arguments: #('yep, my own cool tool can be opened from the world menu ! :)') Marcus -- Marcus Denker -- http://www.marcusdenker.de INRIA Lille -- Nord Europe.
