Unsolved QSystemTrayIcon tool tip not showing on mouse hover
-
I have setup a QSystemTrayIcon with a tool tip but it doesn't show up on mouse hover. I'm running Qt 5.8 on Ubuntu 17.04
Here is the setup code:
QSystemTrayIcon *m_pTrayIcon = new QSystemTrayIcon(this); QIcon icon(*m_pImage); m_pTrayIcon->setIcon(icon); m_pTrayIcon->show(); m_pTrayIcon->setToolTip(tr("ToolTip Test));
I do not see the tool tip show on mouse hover over the system tray icon. Do I need to capture a mouse hover event in order to have this shown?

@anshah said in QSystemTrayIcon tool tip not showing on mouse hover:
m_pTrayIcon
m_ prefix is usually used for class members, but you're declaring a new local variable here:
QSystemTrayIcon *m_pTrayIcon = new QSystemTrayIcon(this);
Where is this code executed? Do you have a class member called m_pTrayIcon? Did you make sure m_pImage is a valid image?

@jsulm
So m_pTrayIcon is a class member I just added for the purposes of clarity so you could see the type. Yes, m_pImage is a valid image. Everything works fine...I am just not getting a tool tip to show. -
Hmm, I have a program that also uses QSystemTrayIcon, and the tool tip text is shown both on my Windows 7 and my Windows 10 PCs, here's the code:
trayIconMenu = new QMenu(this); trayIconMenu->addAction(quitAction); pTrayIcon = new QSystemTrayIcon(this); pTrayIcon->setIcon(QIcon(":/Images/TrayIcon.ico")); pTrayIcon->setVisible(true); pTrayIcon->showMessage("balloon title","balloon message"); pTrayIcon->setToolTip("this is the tooltip"); pTrayIcon->setContextMenu(trayIconMenu); pTrayIcon->show();
Edit: sorrry didn't see until now that your'e not on Windows. I tried the above code on my Ubuntu 18.04 with Qt 5.13.0, while everything works the same as on Windows PCs except there's no tooltip text visible :-(
Maybe some design limit in Ubuntu's desktop...

Thanks for the reply! Looks like your using everything latest and greatest. I'm using Qt 5.8 on Ubuntu 17.04.
Maybe this is a design limitation on Ubuntu. If any of you "QT Champions" can confirm this that would be great!Also, same deal on CentOS, RHEL, Fedora?

Hi,
Are you using the Qt version that comes with your distribution ?
From what I remember, the Ubuntu guys used to patch Qt to integrate with their desktop shell.
-
@sgaist I'm using a Qt 5.8 manual install.
-
Then, please try the version provided by the distribution just to check if it behaves as expected.
-
@SGaist Sorry for the long delay in response as I got pulled off to other issues now I'm back on this one. So to answer your question I tried again with the Qt Version that comes with my Ubuntu distribution and the tooltip still does not pop up.
I'm am using Ubuntu 18.04 with Gnome Desktop (3.28.2) .

@SGaist, I faced the same problem on Ubuntu 20.04. I have Qt5 and Qt6 installed, in both versions toolTips are not displayed. However, in Windows 10 everything works without problems.
Windows 10:
Ubuntu 20.04
