I got tired of writing C, so I wrote some prototype GUIs in Python.
So here's 4, all rolled into 1 script. To switch between the four,
you need to set the TRACKER_UI_LAYOUT environment variable, so
TRACKER_UI_LAYOUT=1 ./tracker-gui-prototypes.py
Uses a GtkComboBox to select services; results in IconView
TRACKER_UI_LAYOUT=2 ./tracker-gui-prototypes.py
Uses a GtkTreeView + ListStore to select services; results in IconView
TRACKER_UI_LAYOUT=3 ./tracker-gui-prototypes.py
Uses a GtkNotebook to select services; results in IconView (broken...I
can't create the tabs until I know which services are relavant to the
results)
TRACKER_UI_LAYOUT=4 ./tracker-gui-prototypes.py
Just finds everything and puts it in a GtkTreeStore
You can also change the number of results returned at once by setting
the TRACKER_MAX_RESULTS environment variable,
TRACKER_UI_LAYOUT=1 TRACKER_MAX_RESULTS=50 ./tracker-gui-prototypes.py
Would show fifty at a time..default is 20.
