We want to set some custom backgrounds for the visualizers, and
those need to track with the current theme. SpThemeManager will
watch the systems theme changes (including dark theme) and
update the loaded CSS resources as necessary.
This allows us to have the SpVisualizerView grow and shrink
along with the visualizer content up until the user has manually
moved the paned handle. At which point it clamps to that
position as allowed by the size request phases.
This uses the new ZoomManager to wire up zoom controls for the
main window. We had to switch away from GMenu to give ourselves
the control we will need for the zoom label of 100% which still
needs to be wired up.
This adds a new helper widget SpVisualizerView to simplify using
visualizers from applications using libsysprof-ui-2 such as
Builder.
We can manage the view range, zoom, etc from this widget going
forward.
We need some sort of scale for content, so we will do this with
an overlay for now. However, we will also want something to be
able to do selections in the future.
This still needs some iteration for correctness, but this sort
of gets the ball rolling.
When set on the window, we seem to lose the value when inserting the
headerbar, resulting in the title being "sysprof" (binary name) according
to the shell. Setting this on the headerbar seems to fix that.
This is a major redesign a modernization of Sysprof. The core data
structures and design are largely the same, but it has been ported to
Gtk3 and has lots of additions that should make your profiling experience
smoother. Especially for those that are new to profiling.
There are some very simple help docs added, but we really need the
experts to come in and write some documentation here.
