In case anyone encounters this thread later looking for a solution:

I was mistaken.  Setting hexpand on the GtkEntry indeed *did* produce the
result I'd wanted.

I thought I'd tried all the permutations, but it seems I was conflating
'expand' and 'fill'.

So: Apologies for the noise.

Re: GtkGrid children and GTK_ALIGN_END

2017-10-12 Thread Daniel Boles 
The wildcard here, and what makes me confused as to whether my own
rationale makes sense, is that you have the grid expanding; I can't
immediately think of cases where I've used such a construct, so I don't
know what I expect it to do! It's also been a while since I thought about
how alignment and expansion interact - I think once you get your program to
a point where it works, the brain begins to remove that information ;) - so
I don't know if anything I've said makes much sense, and would like an
opinion from someone else.

Thanks, that's a handy link.

I'd noticed that too, though it's indeed not what I'd wanted in this case.

But, I can imagine some potential workarounds.


Thanks for your help!

since a test case is always useful...
