What is the best way to render capsule-style toolbar controls (including the label text

  • 0

What is the best way to render capsule-style toolbar controls (including the label text below the buttons) in a Qt application?

As far as rendering the buttons, I want to tap into what is provided by Mac OS as much as possible. (I’m not a Mac developer, so do not know if it has an API for this.) That is, I know I can draw them myself, use style sheets for border-image, guess on the font, and set it all up in a layout, but is there a better way that ensures consistent presentation when Mac updates her “look and feel?” I am using C++ in Qt.

I don’t hate the idea of using Q_WS_MAC to get the platform-specific rendering, but does Qt already have anything for this? You know, a setCapsuleStyle(true) method somewhere? 🙂

Thanks for any suggestions.

    There is a segmented button example in the qt-labs repository that looks decent on KDE. It has a fair amount of #ifdef Q_WS_MAC code, but I don’t know how well it renders on Mac. You can find it here.

    If you are specifically targeting only Mac, you may use the QMacCocoaViewContainer to render native segmented buttons. Its learning curve is quite steep, so you may find this Qt Labs Blog post about Mac widget interesting: Mac widget style addons. The author provides three Mac-style widgets: QtCocoaPushButton, QtCocoaComboBox and QtCocoaSegmentedButton.
