Action at the menubar can't be disabled? Probably a bug of Qt or Ubuntu?

rokemoon

Hm, on Kubuntu it's work fine (I know that problem on Ubuntu, I compile it just for test)

Leon

I am using Qt 4.7.2 (32 bit). How can i found out if am using the QtSDK or the lib’s provided by ubuntu?

Scylla

You can see it on the Qt4 settings page. Or type qmake -query in a console.

Leon

this is my outpout:
@QT_INSTALL_PREFIX:/usr
QT_INSTALL_DATA:/usr/share/qt4
QT_INSTALL_DOCS:/usr/share/qt4/doc
QT_INSTALL_HEADERS:/usr/include/qt4
QT_INSTALL_LIBS:/usr/lib
QT_INSTALL_BINS:/usr/bin
QT_INSTALL_PLUGINS:/usr/lib/qt4/plugins
QT_INSTALL_IMPORTS:/usr/lib/qt4/imports
QT_INSTALL_TRANSLATIONS:/usr/share/qt4/translations
QT_INSTALL_CONFIGURATION:/etc/xdg
QT_INSTALL_EXAMPLES:/usr/lib/qt4/examples
QT_INSTALL_DEMOS:/usr/lib/qt4/demos
QMAKE_MKSPECS:/usr/share/qt4/mkspecs
QMAKE_VERSION:2.01a
QT_VERSION:4.7.2
@

So?

Scylla

So do you use the lib's provided by ubuntu. Try to install the QtSDK which inlcudes version 4.7.3.

Leon

The same again...

This could be a valid bug in Qt or Ubuntu 11.04. The change in the handling of the menu bar in 11.04 may have broken the enabling and disabling of actions. You should report it in the "Qt bug tracker":http://bugreports.qt.nokia.com anyway. I cannot test it, because I'm still running 10.04 for stability..

Is it still not working for you?

I am also working on Ubuntu 11.04, but its working for me.

The Action can be disabled and the Menu is attached to the application and not to the top Unity bar

Leon

At the application i am developing it works fine!
But i just checked the example i have at post#1 and it doesn't work..
It is weird i can say..
@ui->actionAction->setEnabled(false);@
really doesn't work at the example..

Holger

this is how it looks for me, so perfectly fine.

I added the QT Version running on my machine running Ubuntu 11.04

Leon

Hmm i have Qt 4.7.2
How do you update to 4.7.3 at ubuntu?

P.S I don't have Qt SDK

Holger

you can build it yourself for example, but since the problem seems to be fixed in Qt 4.7.3 it is no longer reproducable

This bug is in somewhere in the Xorg. I use 32 bit, Kubuntu, Oneiric, I lost one hour from my development time to realize that it is not my fault. :-|
