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

So @ui->actionAction->setEnabled(false);@ doesn't work for me...

If you want see it yourself: "Link":http://dl.dropbox.com/u/11379868/example.zip

The same with setting an icon while iconvisibleinmenu is true:
@ui->actionHistory->setIcon(QIcon(":/icons/Pictures/time_machine.png"));@

I have to say that this was working at Ubuntu 10.10...

This works here as expect (Ubuntu 10.10)! Are you sure that the propety is not changed elsewhere?

Leon · wrote on 10 Jun 2011, 12:51

Yes see the link.. It is just a button that disables the action, nothing else.. :(

Ok I see. I have tested your example here and it works as exected!
Which version do you use? I'm using the QtSDK and not the lib's provided by ubuntu!

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

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?

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

this is my outpout:

So?

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

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 · wrote on 14 Jul 2011, 16:36

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 · wrote on 15 Jul 2011, 08:30

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

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

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 · wrote on 15 Jul 2011, 08:59

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. :-|
