Tyler Goodlet cc67d23eee Drop old marker drawing code from `LevelLine.paint()`
We haven't been using it for a while and the supposed (remembered)
latency issue on interaction doesn't seem existing after applying the
cache mode. This allows dropping some internal state-logic and generally
simplifying the show-on-hover checks.

Further add `.show_markers()` and `.hide_markers()` as explicit methods
that can be called externally by UI business logic.

Tyler Goodlet 5d65c86c84 Don't delete pp lines or markers
Bit of a face palm but obviously `LevelLine.delete()` also removes any
`._marker` from the view which makes it disappear permanently when
moving from non-zero to zero to non-zero positions.. We don't really
need to delete the line since it can be re-used so just remove that
code.

Further this patch removes marker style setting logic from within the
`pp_line()` factory and instead expects the caller to set the correct
"direction" (for long / short) afterward.

Tyler Goodlet e492e9ca0c Fix pp arrow/label placement bugs
- Every time a symbol is switched on chart we need to wait until the
  search bar sidepane has been added beside the slow chart before
  determining the offset for the pp line's arrow/labels; trigger this in
  `GodWidget.load_symbol()` -> required monkeypatching on a
  `.mode: OrderMode` to the `.rt_linked` for now..
- Drop the search pane widget removal from the current linked chart,
  seems faster?
- On the slow chart override the `LevelMarker.scene_x()` callback to
  adjust for the case where no L1 labels are shown beside the y-axis.

Tyler Goodlet 4f15ce346b Drop splitter resizes except for once at startup
Also adds a `GodWidget.resize_all()` helper method which resizes all
sub-widgets and charts to their default ratios and/or parent-widget
dependent defaults using the detected available space on screen. This is
a "default layout" config method that eventually we'll probably want
allow users to customize.

Tyler Goodlet 445849337f Always resize to slow chart height, not just on changes 2022-09-12 20:25:15 -04:00
Tyler Goodlet 3fd7107e08 Scale view to measured results row count
In other words instead of some static view size previously determined by
the accompanying (slow) chart's height, (recursively) calculate the
number of displayed rows and compute the minimal height needed. This
still caps the view at the height of the chart such that the view will
switch to scroll bar mode when too many results are shown and can't all
be fit in the vertical space.

Deats:
- add a ``CompleterView.iter_df_rows()`` which recursively iterates all
  rows in depth-first order making it simple to compute the absolute
  number of result rows in view and thus the minimal number of pixels to
  show all results.
- always pass the height in the `.on_resize()` handler to ensure
  triggering the height logic when new results are generated in the
  search loop.

much XD

Tyler Goodlet d11dc787a1 First working attempt of search results view scaling
Scales the "view" instance that holds search results to the size of the
accompanying "slow chart" for which the search pane is a "sidepane".
A lot of mucking about was required due to resizing of the view
seemingly feeding back into window resizing and further implementing the
sizing logic such that the parent `QSplitter` can be resized as the
user's whim as well.

Details,
- add a `CompleterView._init: bool` which is set once (and only once)
  after startup where the first display of the current symbol/feed is
  shown allowing and a single *width* padding applied once at startup
  to ensure we don't have an awkward line to the right of the longest
  result.
- in `.resize_to_results()` only apply a minimum height to the view
  using `.setMinimumHeight()` with a down-scaled (`0.91` for now) height
  value from input.
- re-implement `CompleterView.show_matches()` to accept and optional
  width, heigh tuple and when not supplied pull the slow chart's
  dimensions and pass as input to the resize method.
- Make `SearchWidget` x dim sizing policy "fixed".
- register the `SearchWidget` for resize events with god.
- add `.show_only_cache_entries()` for easy results clearing.
- add `.space_dims()` to retrieve slow linked-charts dimensions.
- implement `SearchWidget.on_resize()` which is the caller of all the
  previously mentioned resizing routines.
- do resizing and cache entry showing on search loop startup and be sure
  to clear to cache when the user selects a symbol-feed with Enter.

Tyler Goodlet 1e81feee46 Finally get chart startup view-state kinda correct
It ended up being what'd you expect, races on the accessing shm buffer
data by the UI during the whole "mega-async-startup-everything" phase XD

So we add the following list of ad-hoc startup steps:
- do `.default_view()` on the slow chart after the fast chart is mostly
  fully spawned with the intention being to capture the state where the
  historical buffer is mostly loaded before sizing the view to the
  graphical form of the data.
- resize slow chart sidepanes from the fast chart just before sleeping
  forever (and after order mode has booted).

Tyler Goodlet 40a9761943 Actually support resize events..
Turns out god widget resizes aren't triggered implicitly by window
resizes, so instead, hook into the window by moving what was our useless
method to that class. Further we explicitly define and declare that our
window has a `.godwidget: GodWidget` and set it up in the bootstrap
phase - in `run_qutractor()` during `trio` guest mode configuration.

Further deatz:
- retype the runtime/bootstrap routines to take a qwidget "type" not an
  instance, and drop the whole implicit `.main_widget` stuff.
- delegate into the `GodWidget.on_win_resize()` for any window resize
  which then triggers all the custom resize callbacks we already had in
  place.
- privatize `ChartnPane.sidepane` so that it can't be mutated willy
  nilly without calling `.set_sidepane()`.
- always adjust splitter sizes inside `LinkeSplits.add_plot()`.

More or less moves all the UI related position "nav" logic and graphics
item management into a new `._position.Nav` composite type + api for
high level mgmt of position graphics indicators across multiple charts
(fast and slow).
