Exit freezes under FE - qpdfview

Has anybody had success quitting qpdfview under OS4.1FE?

Has anybody seen any other Qt apps that freeze (complete system lockup) on exit?

I tried running MemGuard to see if that would translate it into a crash, but that froze on me too :(

Trying to determine if this freeze is (a) me, (b) Qt or (c) something I can actually fix.

Just tried the wget pdf manual with it and had no problems, although I'm using FE + beta.

Maybe it depends on the PDF, there's an awful lot of broken ones out there.

Is anybody with a SAM440EP and on-board graphics able to use qpdfview without it freezing on exit?

I'm getting odd system freezes here, and I've noticed there's some hardware scaling problems with CompositeTags() too. They may be unrelated but I'm suspecting the graphics.library or Radeon driver changes are causing the freeze.

It works fine on my system (Sam440 Flex + Radeon 9250) so no freeze at all

The only problem i had is an initial assign requester when i tried to open a file, it asked me to mount the directory where to pick the pdf file to open

Still also some extra output at exit:

Quote:
QSqlDatabasePrivate::removeDatabase: connection 'qt_sql_default_connection' is still in use, all queries will cease to work.


Maybe you can remove that debug for the next release

There's a patch for that. http://www.unsatisfactorysoftware.co. ... /amiga/qpdfview_patch.lha

Very strange. I reinstalled Qt thinking that would fix the freeze too (all I get different is some extra message about WB startup parameters)

Ah thanks for the fix .. about the freeze are you sure you have installed all the latest components of Qt ?

After the full release on Sourceforge Alfkil released a couple of new patches (libQtGui.so and libQtCore.so) ..

Thanks. It didn't help, but I've found the problem:

Native Menus, when enabled, cause a freeze on exit for qpdfview (and probably other Qt apps).

I suspect the changes in the menu system to allow multiple levels has had an unintended side-effect with Qt's handling.

Hopefully when Alfkil is back he will be able to fix this. If the new SDK ever turns up, then the biggest problem with the Qt Native Menus - lack of levels - can be fixed too!

Yep native menus have problems .. menus in general are problematic :-/
