My intention is to use this space for experiments first,
and then as a construction site for a rewrite of the
custom timeline widget.
We really need a rewrite here, in order to be properly
aligned to the standard way of writing such a custom widget,
and also to build our first connection to the UI-Bus and then
remove the old placeholder UI model
over time, a specific Lumiera code writing style has emerged.
The GUI, as it stood, used somewhat different conventions,
which now have been aligned to the common standard.
Basically we use GNU style, with some adjustments for OO-programming,
we prefer CamelCase, and write TypeNames uppercase, variableNames lowercase
verified: basically works
todo: better handling of parse errors.
Currently this is treated as an unexpected exception and just
terminates the whole application, without any suitable diagnostics.
This makes working on the stylesheet somewhat brittle. GTK-3 actually
offers a signal to be invoked in case of CSS parsing errors
(see #953)
Lots off commented out blocks of code
but most issues are related to simple function name changes,
set/get_flags calls, anything that has to do with a Gtk::Style...
Plan of attack from here is to go one-by one of each commented-out or code and update to gtk3 specs.
- split off the tricky basic GTKmm includes
- reduce the clutter in the gtk-lumiera.header
- make GtkLumiera a singleton, placed into static memory
- remove all static functions from WindowManager
