network: Make widgets cover a third of screen width
Following the design decision on other panels, make the central
column of the Network panel cover at most a third of the window,
or more depending on the width of the window.
Since each VPN will be a row in a listbox, we
can't rely on NetVPN:add_to_stack() to handle
the header.
This header must, then, be handled by the panel
itself. For now, we just open the already available
dialog to add connections, when the ideal approach
(to be implemented yet) is to move the contents
of this dialog in a built-in popover.
According to the lastest mockups [1], the Proxy section is now
composed of a row with the state of the proxy, and a settings
button that leads to a dialog where one can configure the different
proxy settings.
This commit ports the current code to do that, and various changes
took place to made this happen. Namely:
* A new ProxyMode enum was added to improve readability and
improve the semantic of the code. No more random numbers
are present.
* The current widgets for editing proxy settings were repacked
into a GtkStack (so that we keep an homogeneous sizing), and
the GtkStack itself was moved into a new dialog. With that,
we can just set the stack page, rather than controlling the
visibility of all individual widgets.
* Many unused widgets were removed.
* The combo box was replaced by 3 radio buttons. Now, there's
no need to deal with GtkTreeIters anymore. Another refactoring
of the code that led to more readable and smaller code.
Overall, these changes made the code be more readable, smaller
codebase with a smaller surface for mistakes.
network: Ensure WirelessSecurity type is initialized
When calling for the wireless security widgets, the code
simply assumes that the corresponding GType is initialized.
This may not always be true, which leads to a nasty crash
every time e.g. we open the network connection editor dialog.
This commit fixes that by introducing a new standard macro
wrapping wireless_security_get_type(), and ensuring the type
is initializing when calling wireless_security_init(), thus
protecting every code path from this crash.
This commit also makes CePageSecurity use the new macro for
better legibility.
The current "Wired" section UI is still optimized for
the old, multi-page panel layout. Recent work [1],
however, suggest that this should change and the standard
widgets be rearranged.
This commit, then, implements this new UI for the wired
devices UI by using a listbox row when there's only one
profile (ditching out the old info labels), and moving
and deleting the bottom action buttons.
After introducing the new single-column layout,
we can easily hit the case where there are too
many connections and/or devices and the panel
gets way too tall.
To fix that, wrap all the widgets inside a
scrolled window that only scrolls vertically.
network: Add connections and devices to different stack
The current Network panel is composed of a single stack and
a treeview to select the currently visible stack page. Each
stack page represents a connection or device.
The new Network panel, however, has none of the concept of
selectable pages. In the new layout, all connections and
devices appear all at once in a more compact and simpler
fashion.
This commit, then, starts moving towards a unified, pageless
panel by adding all the connections and devices to different
stacks. These different stacks are transient to the network
object, and are added at appropriate boxes, giving the panel
a unified layout.
This has some serious implications in the design of the
current code. Most of the code removals were related to the
treeview and different pages handling. No more tree model
madness is present, and the devices are now stored in a
plain simple GPtrArray.
After this patch, NetObject:add_to_stack isn't a good code
design choice anymore. This will be addressed in a future
patch.
