[Solved]how to add combo box in trayicon menu?

goetz

A combo box in a tray icon's menu - weird. I hope I never run into the situation of using such a user interface, sorry.

Hey, I did not come up with that requirement, but I agree it's probably a bad idea. It is possible, though.

mady

Finally! You got what I am asking.
Let me tell you the requirement. I wanted to add a list in tray menu which will be having some options, once user click on it a drop down list will be visible and it will contain those options. I thought combo box will help. Let me know if any other option is available to achieve the same.

andre

How about having checkable (possibly exclusive) menu options instead?

mady

Can I add radio button in tray menu? Because otu of those option user can select at a time only one.

andre

Yes, you can. See [[doc:QActionGroup]].

Thanks Andre,
I have successfully able to create QActionGroup But how to add it into Qmenu that is not given any where in the link given by you. could you please help me to find out how to add QActionGroup into Qmenu?

Thanks in advance. :)

Hey,
I am able to add
but somehow leftAlignAct->setChecked(true); not working for me. I am not able to marked as checked any action in the group.

andre

Adding should work like this:
@
myMenu->addActions(theActionGroup->actions());
@

On the not being able to mark an item as checked: could you show some code please? The code you show is from the example on the QActionGroup page.

I am working on a updater module which will be having a tray menu. Below is the code piece I am working on.
@
........
Once1DayAction = new QAction(tr("Once in every day."), this);
connect(Once1DayAction, SIGNAL(triggered()), this, SLOT(UpdateGroupActs()));

 Once7DayAction = new QAction(tr("Once in 7 days."), this);
 connect(Once7DayAction, SIGNAL(triggered()), this, SLOT(UpdateGroupActs()));
 Once7DayAction->setChecked(true);
 
    
alignmentGroup = new QActionGroup(this);
alignmentGroup->addAction(Once1DayAction); 
alignmentGroup->addAction(Once7DayAction); 

 // create tray icon menu
 trayIconMenu = new QMenu(this);
 trayIconMenu->addSeparator()->setText(tr("Updates"));  // Separater is visible but Text is not visible in the menu.   
 trayIconMenu->addActions(alignmentGroup->actions());
 trayIconMenu->addSeparator();
 trayIconMenu->addAction(quitAction);
 trayIcon = new QSystemTrayIcon(this);
 trayIcon->setContextMenu(trayIconMenu);

........

Note: I tried to use "checkedAction" to see whether any thing is checked but it is returning NULL, seems nothing is set.

goetz

For some reason you must call setCheckable(true) on the actions to become checkable.

mady

Hi Volker,
I tried both setChecked(true) and setCheckable(true) but none of them help. Not sure what is causing this problem. Please let me know if you have any clue.

goetz

I don't have any further ideas now. It did not work for me without calling setCheckable at first. After adding that, I could check the menu entries.

Which OS are you using?

mady

Thanks Every one thanks for your support and petience. It is working now. I had to use both in particular order.
