I ended up going the canvas% route. To reduce the amount of screen space
that had to be redrawn when updating the progress bar or changing the
status text, I created my own message% and gauge% classes based on canvas%.
The final arrangement was a custom panel% that stretched its children out
to the
Excellent! Thank you for the addition.

Otherwise, I don't think there's a good way to use `thing-doc` to
document syntactic forms.

Sorry, no. The repair came relatively late in the v6.1 release process.

There's currently no way to set the background color for `message%`
objects, and I'd still use a `canvas%`.

Sorry for the long delay here.
There's no particular reason for the absence of `close-port`, as far as
I know --- just that `close-input-port` and `close-output-port` were
always there.
It's possible for a value to represent both an input port and an output
port, so if that matters at all, you mi

I think this may be a problem in macro expansion with submodules.
The `#%module-begin` from `racket/base` adds a submodule declaration
for `configure-runtime` when it doesn't see an existing submodule
declaration for `configure-runtime` --- but it looks for an existing
declaration as an immediate

If you're not already in the handler thread (which is the same as the
initial thread for the initial eventspace), then you can use
`queue-callback` to run a thunk in the current eventspace's handler
thread.

set as dynamic parameter via `parameterize'?
how do i get to GUI thread to accomplish that?

Another possibility is to set the `uncaught-exception-handler`
parameter (in the eventspace's main thread).

Your question is somewhat generic. You will need to equip each callback/event
handler with an exn handler that puts the exception into a channel so that
another thread can pick it up. -- Matthias

That's awesome!
Thank you Matthew and those who made this possible, this no doubt improves
a lot the usability of packages.

Hi!
Is it possible to set an exception handler to GUI message loop, so
that any exception thrown in GUI thread can be handled?
