Until further notice, I'm assuming this is a race condition I've created and that I just don't understand concurrency.
from ui.
Can you provide some sample code? (I do need to write documentation...)
from ui.
Sure, the code is here, and the problem is in main.go. main() starts listAccounts() as a goroutine, and when the user clicks the "Add" button to add a new account, listAccounts() starts editAccount(), passing it the address of an Account struct, then waits for it to finish changing the contents of the struct. My operating assumption is that I need to put a lock in here somewhere.

For what it's worth, the race detector didn't find a race here. Here is the full error message I'm getting at the moment.
from ui.
I stripped the program down to its bare essentials: just a window with a button that starts a goroutine to open a second window. The program is still unstable, and crashes with X-related errors like this:
(ui-test:14391): Gdk-WARNING **: ui-test: Fatal IO error 11 (Resource temporarily unavailable) on X server :0.
Or like this longer error. Any idea what might be the problem?
from ui.
And I figured out the problem: you can't open a second window in a goroutine. When I remove "go" from before the call to the function that opens the second window, the crashes disappear.
from ui.
Right, you'll need to do ui.Do() in that goroutine call as well.
I really wish I didn't need to use that hacky workaround, but my previous attempts at using channels for events caused lots of problems :(
from ui.
Oh, I see -- ui.Do() is necessary anytime you call a goroutine that opens a window, not just in main()? I hadn't understood that from the documentation.
Simply dropping "go" and calling it as a normal function seems to be working perfectly well for me so far. Thanks for your replies -- if I can help with documentation, let me know!
from ui.
Right, because your code is technically still running in ui.Do() =P The docs need work, yes; I did write a getting started guide on the wiki.
