Refactor MainViewCB and Navigation.Item
Changes to MainViewCB
---------------------
This is a siginificant restructuring of the main controller in the
system and suggests a number of ideas and practices that should be
applied when refactoring the rest of the controllers or designing new
ones. UI code is inherently verbose; as such, the best we can do is to
structure a controller such as MainViewCB in a way that minimizes the
verbosity as much as possible and focuses on making what is happening as
clear as possible. That's why (as is described further below), almost
everything important now happens in the #initialize method. A major goal
of this change is that developers are able to look at MainViewCB and
read its #initialize method like a script. Indirections to other methods
are minimized as much as possible. The primary focus is on readability
(and therefore maintainability).
These changes began as an effort to substitute a mocked-out "backend",
i.e. bitcoin and p2p infrastructure, such that the application could
be run as quickly as possible, without the need for network
sychronization, bootstrapping, etc, for the purposes of UI development
and testing. Trying to make that change naturally evolved into this set
of refactorings. So at this point, MainViewCB is still "hard-wired" to
live bitcoin and tomp2p backends, but changing that, i.e. providing
mocked-out backends will be that much easier and clearer to accomplish
now.
Specifics:
- Use public vs. private contstructor. This allows for the possibility
of unit testing, avoids spurious warnings in the IDE, and generally
adheres to the principle of least surprise.
- Orchestrate creation and composition of components within the
#initialize method. This avoids the need for member fields almost
entirely.
- Extract and delegate to private methods from #initialize only where
it helps readibility. In general, this change assumes that initialize
should be "where the action is": if the layout of a particular view
is complex, then deal with that complexity directly within the
#initialize method. However, if the creation of a given component is
particularly verbose--for example the creation of the splash screen,
then extract a #createSplashScreen method that returns a VBox. The
same approach has been applied in extracting the
#createBankAccountComboBox, #applyPendingTradesInfoIcon and
#loadSelectedNavigation methods.
- Extract the NavButton member class to cleanly encapsulate what it
means to be a ToggleButton on the Bitsquare application navigation.
This approach is similar to the MenuItem class in
AccountSettingsViewCB.
- Use "double-brace initialization" syntax for JavaFX components
where appropriate, e.g.:
HBox rightNavPane =
new HBox(accountComboBox, settingsButton, accountButton) {{
setSpacing(10);
setRightAnchor(this, 10d);
setTopAnchor(this, 0d);
}};
This approach, while typically rarely used, is an especially
appropriate fit for JavaFX UI components, as the the allows for both
maximum concision and clarity. Most JavaFX components are configured
through a combination of constructor parameters and setter method
invocations, and this approach allows all of them to happen at
construction/initialization time.
- Remove class section comments. In general--and as @mkarrer and I have
discussed--these `////...` blocks shouldn't be necessary going
forward. The goal is classes that are as small and focused as they
can be, and they should be self-documenting to the greatest degree
possible.
- Remove empty lifecycle methods from the ViewCB superclass.
- Remove Profiler statements. These are fine for specific debugging
sessions, but should otherwise be removed for normal use.
Changes to Navigation.Item
--------------------------
These changes to the Navigation.Item enum were made in support of the
refactorings above, particularly in support of the newly extracted
NavButton class being as concise to construct as possible.
- Introduce Navigation.Item#getDisplayName
Push navigation button titles, such as "Overview" for HOME, "Buy BTC"
for BUY, etc. into the Navigation.Item enum itself. This can later be
refactored to support I18N, e.g. by embedding a message label instead
of the actual english word. Not all Navigation items have a display
name yet (and it may or may not make sense for them all to have one).
The default value is "NONE".
