Oh,

sorry, I did not explain my problem clearly: I am working on a laptop with no 
mousewheel available.
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

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. Linux/X11 uses Buttons 4-5
instead.

unfortunately the object assigned to eventBuffer is an ordinary Array containing
'raw' event information. ( 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.

Thanks, Chris

[Pharo-project] simulating Mousewheel

2010-02-19 Thread 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

I just ran the tests that come with

PharoCore-1.0-10508
PharoCore-1.1-11196

using the image as it is.

I updated to Gofer-Tests lr.115 and now I see, that #testSubDirectoryRepository 
has been removed in that version...

Why do you think so? Is 'FileDirectory slash' broken on platforms other than 
Windows?

[Pharo-project] GoferApiTest failing (WinXP)

2010-02-13 Thread Ch Lamprecht
Hello to everybody,

running the tests in latest images PharoCore-1.1 and 1.0 on WinXP I see
GoferApiTest>>#testSubDirectoryRepository failing.
It could be fixed by changing

MCSubDirectoryRepository>>#description

+   ^ directory pathName, FileDirectory slash , '*'
-   ^ directory pathName, '/*'

The current implementation works because '/' and '\' both are valid path 
separators on windows. Assuming '/' as path delimiter would cause trouble with 
MacFileDirectory - but that might be obsolete anyway.
So may be the test is too strict?

I just started to follow this list and the Pharo project ('Recreational 
programmer' btw. - thanks for the kind welcome message ;) ). Should I report 
this? And if so: It is a MC issue, should it be reported using the Pharo 
tracker 
or somewere else?

Cheers, Christoph
