The QML2 UI is a new UI being currently developed to provide a more modern look and feel to Navit.

Prebuilt image

We have a prebuilt image for raspberry pi 2/3. This is a preview and will require more work, but feedback is welcome.

Tweaks (default config file is in /usr/share/navit/navit/xml) :

  • you might want to tweak the default zoom setting (in this image it's 32)
  • you can disable the qt5_qml GUI and switch back to internal, it'll still use EGL

Prerequisites

The QML2 UI is currently developed against QT 5.7

The easiest way to install QT 5.7 (or greater) is probably to use the QT online installer.

For linux, https://download.qt.io/archive/online_installers/2.0/qt-unified-linux-x64-2.0.5-2-online.run.mirrorlist

For other platforms, https://download.qt.io/archive/online_installers/2.0/

Building

If you have Qt5 installation in standard paths, simply cmake will create the Makefile and you can proceed with it. When the Qt5 installation is in the non standard paths, you have to use CMAKE_INSTALL_PREFIX for navit to find Qt5 files.

 cmake -DCMAKE_INSTALL_PREFIX=$QT_INSTALL_PREFIX_PATH  $NAVIT_SOURCE_PATH

Enabling the QML2 ui

Once you compiled Navit, you can enable the QML2 ui from navit.xml.

  • Change your graphics driver to qt5 :
<graphics type="qt5"/>
  • Enable the QML2 UI :
<gui type="qt5_qml" enabled="yes" />
  • Disable the internal UI :
<gui type="internal" enabled="no">
