Qt – Is the Qt 5 dark Fusion theme available for Windows

qtqt5stylesheetthemes

After some research I found out, that Qt 5 now offers a so called Fusion theme which is desribed in one of their blog posts. I really like the theme with the black color configuration you can see in the last picture and I would like to use this in my application but it seems like this color scheme is forced by Unity/Gnome3 (looks like an Ubuntu window) so I am eager to knowing whether there is any available stylesheet or workaround to apply this dark version of the theme to an application.

I'm sure you already found it, but, as TheBootroo said, Fusion theme is controlled by the color palette.

I've found a recreation of the palette here. It isn't complete at all!

qApp->setStyle(QStyleFactory::create("Fusion"));
QPalette p = qApp->palette();
p.setColor(QPalette::Window, QColor(53,53,53));
p.setColor(QPalette::Button, QColor(53,53,53));
p.setColor(QPalette::Highlight, QColor(142,45,197));
p.setColor(QPalette::ButtonText, QColor(255,255,255));
p.setColor(QPalette::WindowText, QColor(255,255,255));
qApp->setPalette(p);

Edit: I've created a gist so we can make it feature-complete.

Windows – changing the color of MDI child windows under Windows 7

It's not a great solution, but poking around on the web, I found this article about how to place a WinXP rounded look into the squarish flat Win95/Win98/Win2k window style. It works by using BMP snapshots of the WinXP theme and than using bitblit functions to stretch them to appropriate sizes around the window frame border. I tried his demo software, and sure enough, it looks like WinXP Luna under Win7. I can use his example as a basis to hook and replace my MDI child window frame drawing.

The problem with this approach is that you either have to pick a titlebar width and stick with it and not respond to global theme adjustments that change the titlebar height, or you have to take many different BMP snapshots at different sizes. For my purposes, it is probably fine to just stick to one thickness and ignore user theme adjustments. Once in place, I can apply different themes just by BMP snapshotting them - so I could also apply the Office 2007 MDI child look as well.

Android – How to change theme for AlertDialog

In Dialog.java (Android src) a ContextThemeWrapper is used. So you could copy the idea and do something like:

AlertDialog.Builder builder = new AlertDialog.Builder(new ContextThemeWrapper(this, R.style.AlertDialogCustom));

And then style it like you want:

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <style name="AlertDialogCustom" parent="@android:style/Theme.Dialog">
        <item name="android:textColor">#00FF00</item>
        <item name="android:typeface">monospace</item>
        <item name="android:textSize">10sp</item>
    </style>
</resources>
