Hi all, i use Qt 4.8.1. When i want show my widget on fullscren i use QWidget::showFullScreen() - and this good work, but if i use this on retina display, widget show quarter(1\4) screen. How this fix ? I tried use

<key>NSPrincipalClass</key>
<string>NSApplication</string>

<key>NSPrincipalClass</key>
<string>NSApplication</string>

To copy to clipboard, switch view to plain text mode

<true/>

<key>NSHighResolutionCapable</key>

You'll need to log out and log back in, or drag and drop your bundle to a different location so the new plist takes effect.
