Introduction

Application

This example shows how to bring an application to foreground using osso.Application.application_top().

• osso_test_app.py - Application that will be brought to foreground.
• osso_test_app.service - Service file for the target application.
• osso_test_sender.py - Application that will call the OSSO service.

Auto-saving / State Saving

These examples show how to use the auto-saving and state saving features from python-osso. Each file is a separate example.

• osso_test_autosave.py - The same objects from the example below, but instead of calling the save function directly, any changes call user_data_changed, and when exiting force_autosave is called.
• osso_test_statesaving.py - Creates a gtk.Entry and a gtk.HScale. It saves the state when the application goes to background or exits, restoring the state on the next startup, unless the device resets or is turned off.

Device State

These examples show how to interact with the display and the device.

• osso_test_device_on.py - Requests to turn on the display.
• osso_test_device_blank_pause.py - Requests to do not blank the screen. This will keep the screen on for 60 seconds.
• osso_test_device_state_cb.py - Registers a callback for device state changes (Offline mode, etc...).

• osso_test_help.py - Shows two buttons: one to load a help topic and another to open a dialog with an "?" button in titlebar.

• osso_test_mime_category.py - Prints the category the specified mime type is in.

• osso_test_mime_open.py - Opens an file using the default application for its mime type.
• osso_test_mime_icons.py - Shows icons associated with a given mime type.

• testplugin.c - Test plugin.

RPC

These examples show how to make remote procedure calls using python-osso.

• osso_test_sender.py - GUI app that requests a service from the target app.
• osso_test_receiver.py - Sample service that will be called by osso_test_sender.py

Status Bar

This example shows how to send events to status bar applets.

• osso_test_statusbar.py - Requests the display applet to change the display brightness.

• osso_test_note_dialog.py - Shows a dialog note.
• osso_test_note_infoprint.py - Shows an information banner.
