What do you mean when you say that it awaits tools to activate?

Carl,

There is no fly by help mechanism in Pollock as yet. Tools will add  
that in the future. Getting and setting of the text is all that  
Pollock itself supports.

I kind of see Carl's point though, what is so inherently special about hover
help that makes it part of tools? I would have thought that buttons and
scrollbars responding to mouse clicks is not unlike all widgets responding
to mouse hovers?

Cheers!

I wasn't trying to make that point, but you did rather well.  I don't
understand why this isn't in there already.  Perhaps Vassili likes this
particular piece of work and asked Sam if he could tackle it?  ;-)

More like Vassili has a Generic State Transition Framework as well as  
a prototype, that will be released as a tool along with Splash.

Just a quick update on the progress. It seems that the bug was located
and squashed, it will however require a new VM build. The conclusion is
that it likely affects all Unix VMs, not just Linux. It's not clear to
me yet if this will be deemed enough to trigger a release of an official
bug fix VM at this point. It should make the 7.5 VMs at the latest though.

Thanks to all for helping out with this.

Thanks for the update.

I don't know how much making an official bug fix VM costs you in time,
but I tend to vote for releasing a fix sooner rather than later. In a
development environment this is just an annoyance, but a significant
annoyance -- I sit there connecting and disconnecting from Store until I
finally get a connection that doesn't hog my CPU.

However, in a production situation consuming a CPU per VM would just not
be acceptable, so I could not recommend using this VM version in most
production situations.

How can I open an instance of DialogWindow that doesn't cause VisualWorks to
lock until the window is closed?  I tried the most obvious idea of having a
custom openNonBlocking method that calls super open.  Didn't seem to make
any difference.  :-(

Thanks,

I should make clear that this was a very early update. There were no
discussions or decisions about a bug fix VM yet, so don't take my note
as a sign of it coming or not. I just wanted to provide a bit of early
feedback.

Nevertheless I will forward your comment to the relevant parties.

Thanks,

Martin

Look at DialogWindow>>windowType.
Additional locking is done by grabing the mouse. See DialogWindow>>open.

There are two parts to dialog locking, one part is as
Christian said, mouse grabbing in the image. The other part
is done by the VM, or the OS, and is specified by the window
type. If you look at the debugger you will notice that when
it grabs control and a dialog was open it changes the window
type of the window as well as releasing mouse grabs.

You can kind of simulate dialogs by using a combination of
mouse grabs and insuring the window stays on top by reraising
it if it gets covered. I recall someone writing about using
this technique a few months ago.
