I have a QML Audio element in my app that plays a sound. When I click a button I execute:
audio.play()
and when I click it again I execute:
audio.stop()
Ideally I would like to fade the sound in a little when the user clicks the button to play the sound, and fade it out a little when they press the button to stop the sound.
How do I do this?
I just bought a Fitbit One which includes Bluetooth 4.0 to sync with mobile devices. Currently libfitbit does not include support for bluetooth syncing, so I would like to see how much data I can get out of the device that I can pass onto the libfitbit devs so that they can explore bluetooth support.
I ran:
hcitool scan
which unfortunately did not return any devices. I also used blueman to scan for devices and nothing was found either.
Therefore I am assuming that the bluetooth radio in the device is not visible by default.
Can anyone recommend any ways to get data out of the device that could be helpful?
In the Ubuntu Accomplishments project we are having a few unusual bugs:
Namely that we have a window with a GtkNotebook and a GtkIconView on a page and another on another page.
When the user re-sizes the window the iconview does not automatically fill the space with icons (they stay in their original column layout) but if the user changes the GtkNotebook pages and thus refreshes the icon view the space is taken up as expected. How can we automatically use the space when resizing the window?
What is more concerning though is that when the window appears, we can resize it smaller - it seems as if the iconview is blocking us from resizing and then having a scrollable region for the icons.
The code looks like this. The ListStores that drive the IconViews:
self.trophystore = Gtk.ListStore(str, GdkPixbuf.Pixbuf, bool, bool, str, str) # title, icon accomplished, locked, app, accomplishment
self.trophystore.set_sort_column_id(COL_TITLE, Gtk.SortType.ASCENDING)
self.trophy_icon.set_model(self.trophystore)
self.oppstore = Gtk.ListStore(str, GdkPixbuf.Pixbuf, bool, bool, str, str) # title, icon, accomplished, locked, app, accomplishment
self.oppstore.set_sort_column_id(COL_TITLE, Gtk.SortType.ASCENDING)
self.opp_icon.set_model(self.oppstore)
self.trophy_icon.set_text_column(COL_TITLE)
self.trophy_icon.set_pixbuf_column(COL_PIXBUF)
self.opp_icon.set_text_column(COL_TITLE)
self.opp_icon.set_pixbuf_column(COL_PIXBUF)
Other than this, we don't really poke around with the IconViews, we just add content to the ListStores to update the views.
The code for the project is here - can anyone recommend how we can fix these two issues?
As part of the Ubuntu Accomplishments system I have a daemon that runs as well as a client that connects to it. The daemon is written in Python (using Twisted) and provides a dbus service and a means of processing requests from the clients.
Right now the daemon is just a program I run before I run the client and it sets up the dbus service and provides an API that can be used by the clients.
I want to transform this into something that can be installed and run as a system service for the user's session (e.g. starting on boot) and providing a means to start and stop it etc.
The problem is, I am not sure what I need to do to properly daemonify it so it can run as this service. I wanted to ask if others can provide some guidance. Some things I need to ask:
In responding, if you can point me to specific examples or solutions I need to implement, that would be helpful. :-)
Thanks!
I am writing a project with Quickly and GTK 3 and I want to use the get_media_file() helper so I can load an icon in my data/media directory.
I can't see how I use get_media_file() with the latest quickly; it looks like the Quickly helpers have changed.
Can anyone provide me with some sample code of how this works?
I am writing a small Python and WebKit app; I am using WebKit as the UI for my app.
What I want to do is to create an interactive element in WebKit (namely a combo box or a set of clickable regions) and when the user interacts with these elements I can call a Python callback to do some processing and then update the WebKit view with new information.
Here is an example of what I want to do:
on_combo_selected() is called in my Python script which then grabs some data.How can I do this?
