[Qt-interest] any elegant to handle toolbar visibility?

[Ross Bencina]

Hi Alex

The question seems clear to me. I'm not sure if it's a bug that when the 
main window is hidden its undocked widgets remain visible -- this seems like 
a bug to me though.

I would say fixing the bug is one reasonable solution. Anything else, seems 
to me is going to involve some level of "customize saving and/or loading 
widget states routine" although that might not be too bad:

save current dock widget state using Qt routinces
store list of visible undocked windoids
hide undocked windoids

(switch views)

show undocked windoids from stored list
restore dock widget state using Qt routines


Note that if you name your dock widget objects carefully it is not too hard 
to write a compact routine that iterates all child dock widgets of a parent, 
and writes their names to a QStringList (which can then be persisted) and 
can be used to reload them too.

Ross.
