User reported wanting to mark text in-game and copy it out (item names,
coordinates, NPC dialogue, etc). ImGui doesn't natively let you select
across multiple TextColored widgets, but a read-only multi-line
InputText is fully click-drag selectable + Ctrl+C copyable. This
commit adds a "Copy mode" toggle to ChatPanel that swaps the chat
tail's render path between the colored-line view and a single
selectable text region.
New IPanelRenderer primitive:
void TextMultilineReadOnly(string id, string content, Vector2 size);
ImGui maps this to InputTextMultiline with the ReadOnly flag — same
selection + Ctrl+C UX a user expects from any text-input widget.
FakePanelRenderer records the call for tests. The future D.2b
custom retail-look backend implements its own equivalent (likely
the same widget pattern with retail font/skin).
ChatPanel rendering:
· A "Copy mode (select text to Ctrl+C)" Checkbox at the top of
the panel toggles _copyMode.
· Off (default) — current per-line render with colored combat
entries. Visually unchanged from before.
· On — the chat tail becomes a single TextMultilineReadOnly
widget holding every visible line joined with newlines. Loses
per-line color, gains arbitrary-span text selection.
· Footer (separator + input field) renders identically in both
modes so the user can still type while in copy mode.
Existing ChatPanelLayoutTests's footer-separator probe was using
IndexOf("Separator") — which now matches the new pre-tail separator
between the Checkbox and the chat tail. Switched to LastIndexOf
which still pins the footer separator (between EndChild and
InputTextSubmit). Behaviour and intent unchanged.
DisplaySettingsTests' With_expression test was still asserting the
old "1920x1080" Default.Resolution; updated to the new "1280x720"
that the previous wire-up commit introduced (the earlier commit
forgot this one).
