I
have a puzzle in using the scroll wheel in Pharo 3.0. Lately
I have been playing with Moose 4.8, which I think is Pharo
2.0 plus some extras, and with a fresh download of Pharo
3.0. In the Moose image, if I open a system browser, for
example, I find that the scroll wheel will scroll whichever
pane the cursor is in. In Pharo 3.0, it is necessary to make
a pane active, by clicking in it, before it can be scrolled.
I find the first possibility more convenient; for example,
if I click in the categories pane to make it active, it
almost always has the effect of making a selection from
among the visible categories, which is not what I want. Is
there any easy way of fixing the Pharo 3 image so that it
will have the effect of scrolling the pane - or the window -
which contains the cursor? I have searched the settings
browser headings, but I could not find anything that looked
relevant.
Some
years ago, I poked into the innards of Dolphin Smalltalk and
tweaked it to produce the effect I want. It was not a major
change, so it might be educational for me to try the same
trick in Pharo.
