I am trying to make a very simple toolbar in a QMainWindow on a Mac, with Qt 5.2.1, with not a single satisfaction. I was using still Qt 4.8 but I thought I'd give Qt5 a try.
As QtMacExtras are concerned, I don't find the native toolbar class anymore, except in private headers. So I tried a simple QToolbar.
I have a very basic and stupid toolbar:
setUnifiedTitleAndToolBarOnMac(true);
toolbar_ = new QToolBar(this);
toolbar_->setMovable(false);
toolbar_->setFloatable(false);
toolbar_->addAction("h");
toolbar_->addAction("w");
toolbar_->addSeparator();
toolbar_->addAction("f");
As you can see, well, it isn't acceptable.
Is there any chance, by some arcane and weird means, that I could have a nice unified, or better "native look and feel", toolbar on a mac?
QMainWindow::addToolBar(QToolBar *toolbar) should do it.
The NSToolbar does not form part of the Qt widget hierarchy, so your admirably idiomatic conference of parenthood from the main window to the toolbar is working perfectly to specification, yet is obviously dissatisfying.
However, as the Trolls say in the QMainWindow documentation:
"You add a toolbar to a main window with addToolBar()."
Here is the effect as shown in rsync client for Mac.
I don't have my mac with me otherwise I would give this a quick test. I was surprised when browsing how many bugs are still being reported for Mac. I did find this article, which does appear to have better looking toolbar.

How to create an application which stays in top of MacOS, something similar to below image. You can see the Evernote elephant icon.
I don't want to use xcode - because my application already built in QT, it has nice GUI, now I wanted to add extended feature something similar to Evernote. If I click on an elephant it will open a dialog box to write notes. In my case- it's a simple event like on/off buttons.
I have tried and created GUI widget apps but how to make one which resides like Evernote app ?
A custom pop up menu like the one pictured can be done several ways in Qt.
QML is the most modern way of making the menu with the customized styling you are looking for.
Apply the appropriate flags to the window/widget so it appears as a popup.
The same effects can also be done in QWidgets, but takes more code and probably will take longer to make. The flags you are looking for will be found under Qt Window Flags and/or under Qt Widget Attributes.
The stock stylings for Qt for different OS's deal mostly with title bars, status bars, buttons, drop downs, etc.
The base styles for Mac can be found here:
http://doc.qt.io/qt-5/gallery-macintosh.html
Once you go to a customized popup, you have to draw all of it yourself... but the native drawing elements in Qt are friendly enough and get you that look you are trying to do.
There are even some tools for exporting from Photoshop or Gimp directly to QML.

Hope that helps.
You are looking for a tray icon. Qt implements it in QSystemTrayIcon.

Many StackOverflow posts exist on this topic.
If you already have a program written for Qt, then you can compile and run it under MacOS/X much the same way you could compile it under (whatever OS you're using now). You'll need to install Xcode because Xcode includes the C++ compiler (clang) you'll need in order to compile your Qt program, but you don't have to use the Xcode IDE if you don't want to. Rather, you can either use the QtCreator IDE under MacOS/X, or you can simply open up a Terminal window and do a "qmake ; make" in the directory where your Qt-based program's .pro file is, and build it from the command line that way.
If, on the other hand, your question is actually about how to add an icon to the global menu of a MacOS/X desktop, then I don't think Qt has an API for that, so you'll need to drop down to using one of MacOS/X's native APIs. That will probably involve learning some Objective-C (or Objective-C++, if you prefer), but integrating a bit of Objective-C/C++ into your Qt app is doable with a bit of work.
I have a UI written in Qt that makes extensive use of dock widgets, primarily so that end users can customize which which docks are available, and how they are arranged.
We recently upgraded to Qt 5.6.1, and the dock widgets can no longer be rearranged on Ubuntu, although they still work on windows and other OS's. When you try to move the docks, the rubber band still appears as usual showing the new location, but when dropped the dock just snaps back into whichever position it started in, which is always tabbed somehow.
After several hours of searching, I think the problem is related to QTBUG-54185, and I'm wondering if there is any way to work around the bug while we wait for the Qt 5.6.2 release which fixes it.
The bug is related to having the AnimatedDocks property disabled. QDockWidget rearranging still works, even in spite of the bug, for dock widgets which are animated.
The problem was that in the code, the main window was setting the dock options manually as
mainWindow->setDockOptions(AllowTabbedDocks);
Since DockOptions are OR'd, what is happening here is that the AnimatedDocks property, which is enabled by default, is being unintentionally disabled. The solution for me was to delete the offending line, since the default options are AllowedTabbedDocks|AnimatedDocks, which is actually what I wanted all along.
I have used Qt previously only in the form of PyQt, and today I tried the original version of Qt in C++.
I got it working, however, when if start up my app, I have several problems with it:
it's stationary, which means, I cannot drag it across the screen
I cannot change the size of the window
it does not have a OS X type status bar (which contains the three colored buttons and the name of the window)
How can I add these features to my C++ Qt app?
I have tried to look for a solution, but only found QtApplication::setStyle();, which did not solve my problem.
You can see the code here.
The code inside your subclass of QMainWindow contains this line:
setWindowFlags(Qt::FramelessWindowHint);
That is probably causing most of the problems you describe. Try removing that line.
I extensively researched this topic, mainly hindered by that I'm not sure I'm using the right words to describe my issue.
So the point is I'm developing a GUI application in C++ with Qt. The app is being developped on Mac and ftm it's intended only for mac deployment.
I want my app to behave much like System Preferences on Mac, thus accessing different views/panes by clicking buttons on the toolbar.
What I want to avoid is to have one separate window for each pane.
The closest thing I found seems to be QStackedWidget however I'm not sure what's the best way for implementing it.
Should I use it as the main class of my application? Or can I treat it as an object of MainWindow? I'm not a Qt Expert so any further insight or suggestion will be much appreciated. Thanks
QStackedWidget is definitely the way to go. Use it as your main 'container' for your widgets and implement a default main panel widget which contains your entry items, then when you click on one you can push it to be the currently displayed widget in the stack. You could try more complicated solutions to achieve it, but it's significantly easier to do with a QStackedWidget and then focus on how the interaction is handled.
We're about to commit to Qt and C++ (sigh) to do some cross-platform development. The latest version of Qt 4.5 seems very nice as does the QT Creator IDE, which although simple compared to other IDEs, is a good way to get started.
I'm trying to understand how to do drag and drop into QT widgets from the "outside" world. As far as I can tell from the documentation, you're supposed to subclass a widget that you want to have respond to drop events and override some methods (the dragEnterEvent and dropEvent member functions) for that widget.
But if I use the Qt Creator tool, I don't seem to have any access to the classes of the widgets that I have created using the GUI form builder and so I can't subclass them.
WHat's the secret?
Thanks in advance,
D
Someone on my team figured it out ---- turns out there is an option to "Promote" a widget, meaning you can subclass it to something else and then override the needed methods with no pain.
Seems to me it would have been more obvious if it said "Subclass widget..." rather than "Promote" but that's OK.
This QT Creator is a very nice piece of work.
I've never used QT creator environment, but I assume it spits out code afterward. Can you edit the code it spits out?
If you subclass the classes in a separate file, it shouldn't get overwritten when you rebuild your app with QT creator environment.
I suppose this is really a question for the QT creator forum though, sounds like a problem in THEIR user interface.
