There are devices with more than 10 enroll stages we should handle, so
instead of hardcoding a grid of images, let's just build this dynamically
using a flowbox
Don't make the UI to block while deleting the saved prints (that might take
some time, especially for devices with internal storage) but just use a task
with a thread that:
- Mark the fingerprint row as unsenstive
- Calls the method to delete prints
- In the same thread, calls the method to fetch the updated informations
- Returns in set_fingerprint_row_cb where we update the UI again
Again this would be nicer to be done just using async calls but this is
something to do in some bigger refactor.
When opening the user panel we g-c-c performs lots of sync operations that
may cause a noticeable slowdown, especially when a fingerprint device is
available, in fact set_fingerprint_label() call leads to:
- DBus sync request of the system bus
- fprintd dbus-activation
+ This leads to sync opening of all the devices, that might also cause
a slowdown, depending on the devices drivers
- Dbus sync calls to the device to get the list of enrolled fingerprints
Only after we've a reply, we update the g-c-c UI and continue the execution.
The fingerprint dialog code would need some global refactor, but to fix this
without big changes, let's just use GTask that runs a thread in wich we do
all the sync operations, and once done we finally update the widget state.
We are currently adding support for Synaptics devices that require 8
steps. Add another row for images which brings us to up to 10
supportable steps for now.
Switch from GtkBuilder to using GtkTemplate.
Rename .[ch] and .ui files to standard names.
Rename widget IDs to be more readable.
Drop widget IDs that are not used.
Move code into the .ui file that can be.
Connect signals in swapped form.
Enroll data are used after destroying when closing dialog. It causes
crash while setting label. Therefor we have to store the pointer for
fingerprint button and use it to set the label after destroying the
data.

When you've enrolled your fingerprints and we show "Done!", hide
the label that asked us to swipe/press our finger on the fingerprint
reader, it's too late.
