This worked with all toolkits (including Java SWT, GTK+, > Firefox's toolkit). So I can't get myself to trust you on that. that's because there was a SPECIAL BUTTON! a special app can grab that 1 button everywhere (thus its not useful for anything BUT the scrolling). also note.. it's WINDOWS. this is NOT windows. this is X. only the tolkit and app know the context of whats inside a window and only they can (sanely) handle mouse events within that window and know what they were for. be they presses etc. yes - given a SPECIAL button it would be possible to intercept and figur eit out - but then.. how do you know WHICH thing to scroll? you have 2 scrollviews in a window? one on the top, one on the bottom. which scrolls? only the toolkit knows which should (ie which one you intiially pressed). yes you could try faking mousewheel buttons and this wont move the thing WITH the finger by the distance the finger moved. ie DRAG thge thing as far as you dragged with a finger as there is no correlation between a mouse wheel press and how far something moves in pixels. it's a toolkit issue, > > 2. right mouse also can be hackishly implemented in the windowing system - > > but thats wrong, as it has no idea what parts of the screen need a long > > press for emulating a right mouse.

Why > not go a level higher and try to solve those problems in a toolkit > agnostic manner? the toolkit IS a higher level. windowing system and window manager are LOWER level. toolkit is as high as you get before being in the app itself. as its the highest level until the app it knows the most about context and meaning of things in a window - what they do, when, how and where. what their intended use is. windowing system, window manager etc. have no visibility on this. they are workhorses doing grunt-work. wm does some grunt and otherwise is in a separated domain devoid of knowing whats up inside an app's window. > > > But if the OpenMoko team thinks that the GUI toolkit is the place to fix > > > scrolling, then I can see why it is a good choice. > > > > thats what elementary covers - it's > > > Good list of features, and I would like to use it to congratulate all > developers on the elementary toolkit on their achievements.

If it is important, > please consider rewriting that last question. not really - but things improving is good. if things just stagnate and dont change you are stuck where you are. bugs, lack of features, tools, uses, etc. will plague you and you continually work around them or just give up and dont do them. it's never a bad thing for thnigs to get better quickly. if they are constantly unstable - that is bad. but reduced instability and more features.. is good. especially if it comes rapidly. -- ------------- Codito, ergo sum - "I code, therefore I am" -------------- The Rasterman (Carsten Haitzler) ras...@rasterman.com _______________________________________________ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
