You can use the [style hint][1] property of QFont: 

    QFont font(&quot;Monospace&quot;);
    font.setStyleHint(QFont::TypeWriter);


If the font cannot be found (which happens with Monospace on Windows), Qt&#39;s [font matching algorithm][2] tries to find a font that matches the given style hint.

You can retrieve the system&#39;s default fixed font using QFontDatabase&#39;s systemFont(..) function.
It was introduced in Qt 5.2.

Example:

    const QFont fixedFont = QFontDatabase::systemFont(QFontDatabase::FixedFont)


For all widgets that accept Rich Text you can simply put it into a `pre` block, i.e. `&lt;pre&gt;This is my Text&lt;/pre&gt;`. It will then use the systems monospace font.

Is there a platform independent way to specify a fixed width font for a Qt widget ?

If I set the font to &quot;Monospace&quot; in Designer on Linux, it is not found on Windows and Arial is used instead.

I am just starting up a new project that needs some cross-platform GUI, and we have chosen Qt as the GUI-framework.

We need a unit-testing framework, too. Until about a year ago we used an in-house developed unit-testing framework for C++-projects, but we are now transitioning to using Google Test for new projects.

Does anyone have any experience with using Google Test for Qt-applications? Is QtTest/QTestLib a better alternative?

I am still not sure how much we want to use Qt in the non-GUI parts of the project - we would probably prefer to just use STL/Boost in the core-code with a small interface to the Qt-based GUI.

*EDIT:* It looks like many are leaning towards QtTest. Is there anybody who has any experience with integrating this with a continous integration server? Also, it would seem to me that having to handle a separate application for each new test case would cause a lot of friction. Is there any good way to solve that? Does Qt Creator have a good way of handling such test cases or would you need to have a project per test case?

How do I set an application&#39;s taskbar icon in PyQt4?

I have tried setWindowIcon, and it successfully sets the icon in the top-left of the main window, but it does not affect the icon shown in the Windows 7 taskbar -- the taskbar icon remains the default Python pyw icon. Here is my code:

    from PyQt4 import QtGui
    
    app = QtGui.QApplication([])
    mainwindow = QtGui.QMainWindow()
    mainwindow.show()
    
    app.setWindowIcon(QtGui.QIcon(&#39;chalk.ico&#39;))
    mainwindow.setWindowIcon(QtGui.QIcon(&#39;chalk.ico&#39;))
    app.exec_()

[update] I&#39;ve tried placing the `setWindowIcon()` before the `show()`. I&#39;ve tried it with other images, ico and png. Nothing helps.

What are the pros and cons of using Qt containers (`QMap`, `QVector`, etc.) over their STL equivalent?

I can see one reason to prefer Qt:

 * Qt containers can be passed along to other parts of Qt. For example, they can be used to populate a `QVariant` and then a `QSettings` (with some limitation though, only `QList` and `QMap`/`QHash` whose keys are strings are accepted).

Is there any other?

**Edit**: Assuming the application already relies on Qt.

STL or Qt containers?

How do I load external fonts into an HTML document?

I have some text that is displayed at run time in a textblock. I want
the font size to be the biggest it can be to fill the area that is
given. I think I have the textblock setup correctly to &quot;autosize&quot; and
I try to increase the font size till the textblock is bigger than than
its parent then decrease the font size by 1. The problem is I can&#39;t
get the control to redraw/recompute its size.

Is the a better way to do that? Or is there a way I can make my method work?

I&#39;m trying to define a GUI layout using XML files in Android. As far as I can find out, there is no way to specify that your widgets should use a custom font (e.g. one you&#39;ve placed in assets/font/) in XML files and you can only use the system installed fonts.

I know that, in the Java code, I could change the font of each widget manually using unique IDs. Alternatively, I could iterate over all the widgets in Java to make this change, but this would probably be very slow.

What other options do I have? Is there any better ways to making widgets that have a custom look? I don&#39;t particularly want to have to manually change the font for every new widget I add.
