Attempts at incorporating the QML GUI into Navit

These are my notes when attempting to get the QML GUI working. To be used when writing a proper wiki page about it...

Current Problems

Bugs

  • POIs Near Position actually gives the POIs near destination. Menu --> Navigation --> POIs Near Position (only shows when routing)
  • POIs Near Destination actually gives the POIs near the current position. Menu --> Route --> POIs Near Destination (always shows).
  • On Bookmark page. When clicking 3rd icon for any bookmark (greyed out X in the images below), Navit crashes with the following message:
file:///home/tim/src/navit/navit/gui/qml/skins/navit/PageBookmarks.qml:121: Unable to assign QString to int
ASSERT failure in QList<T>::operator[]: "index out of range", file /usr/local/Trolltech/Qt-4.7.0/include/QtCore/qlist.h, line 474
Aborted

and inserts the following as the first entry in the Bookmarks.txt file: 

mg:0x0 0x0 type=bookmark label="/"

Subsequent re-starts of Navit are fine, except when trying to re-enter the Bookmarks page, when Navit crashes with the following message: 

ASSERT failure in QList<T>::operator[]: "index out of range", file /usr/local/Trolltech/Qt-4.7.0/include/QtCore/qlist.h, line 474
Aborted

Manual removal of the new first entry in the Bookmarks.txt file resolves the issue.

Feature Problems

  • No icons in Bookmarks, so its impossible to distinguish between a Bookmark folder or actual Bookmark

System

Acer One netbook, 160GB HDD, 1GB RAM, Intel Atom processor.
Ubuntu 9.10
Navit from SVN, r3134

Step 1 - Installing Qt

Finding and downloading

Configuring

Using instructions from http://doc.qt.nokia.com/4.7-snapshot/install-x11.html. In a terminal: 

cd ~/src/qt-everywhere-opensource-src-4.7.0-tp/
./configure
  • During configure:
    • Asks what type to use: Commercial or Open Source. Selected Open Source ('o')
    • Asks to accept licence: Chose 'yes'
  • Configuring... took ~14 minutes

Making and Installing

In terminal: 

make
  • Making... took ~5.5hrs (I'm not joking!)

In terminal: 

sudo make install
  • Installing... ~15 mins

Configuring the Environment

Again, using instructions from http://doc.qt.nokia.com/4.7-snapshot/install-x11.html. In a terminal: 

PATH=/usr/local/Trolltech/Qt-4.7.0/bin:$PATH
export PATH

To check the PATH, in terminal: 

$PATH
bash: /usr/local/Trolltech/Qt-4.7.0/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games: No such file or directory

Step 2 - Re-building Navit

Moving to Navit folder and updating from SVN. Also autogen, configure. Configure is with special switch from http://wiki.navit-project.org/index.php/Gui_QML. In terminal: 

cd ~/src/navit
svn up && ./autogen.sh && ./configure --enable-gui-qml
  • Checked during the configure routine for:
Graphics types: yes (default)
  qt_qpainter:       yes (default)
GUI types:
  qml:               yes (configure parameter)
  • Eeerm, no. Saw:
Graphics types: yes (default)
  qt_qpainter:       no (Package qt-mt present)
GUI types:
  qml:               no (Packages QtGui and/or QtCore missing)
  • Tried after running
export PKG_CONFIG_PATH=/usr/local/Trolltech/Qt-4.7.0/lib/pkgconfig

when configuring the environment. Success: 

  qt_qpainter:       yes (default)
GUI types:
  qml:               yes (configure parameter)

Then install Navit: 

make
sudo make install
  • Success.

Step 3 - Configuring the GUI

Enabling the GUI

In navit.xml: 

<!--<graphics type="gtk_drawing_area"/>-->
<graphics type="qt_qpainter"/>
<gui type="qml" enabled="yes" source="/home/tim/src/navit/navit/gui/qml/skins" skin="navit" width="1024" height="550" icon_src="/home/tim/.navit/xpm/"/>

All other GUI types disabled. Starting up Navit.

  • Navit starts - no crashes
  • Single window, map displays, windowed mode <-- Fullscreen not working
  • No buttons or toolbar <-- Use OSD items
  • Map is draggable
  • The following messages appear when starting Navit:
graphics_qt_qpainter:graphics_priv* graphics_qt_qpainter_new(navit*, graphics_methods*, attr**, callback_list*):enter
** (<unknown>:20437): CRITICAL **: atk_object_set_name: assertion `name != NULL' failed
graphics_qt_qpainter:graphics_priv* graphics_qt_qpainter_new(navit*, graphics_methods*, attr**, callback_list*):return

graphics_qt_qpainter:virtual void RenderArea::resizeEvent(QResizeEvent*):pixmap 0xa1f4380 800x600
  • When clicked (both left and right click), map disappears to leave a blank screen. Navit is still active as GPSD calls are still being made i.e. it hasn't crashed!
    • From the wiki, the menu interface should be displayed when clicked. This isn't so.
    • Notice in printed messages above it expects main.qml in the share directory. Is this hardcoded?
    • Copying files to shared directory and trying again. Fixed using source attribute in <gui> tag.

Testing GUI

Re-starting Navit. Messages: 

graphics_qt_qpainter:graphics_priv* graphics_qt_qpainter_new(navit*, graphics_methods*, attr**, callback_list*):enter
** (<unknown>:20691): CRITICAL **: atk_object_set_name: assertion `name != NULL' failed

  • Note it expects xpm folder in share directory. Fixed using icon_src attribute in <gui> tag.
