📝 WalkthroughWalkthroughThe change adds discrete zoom support for the query editor and database tree. It adds keyboard and Ctrl+wheel controls, persists the zoom step with window state, updates build configuration and documentation, and adds unit and widget tests. ChangesZoom support

🟡 Changes recommended
The new tests/test_zoompresenter.cpp helper uses mapToGlobal(QPointF) which is likely a non-compiling call in typical Qt 6 builds and should be corrected before merge.

Pull request overview
This PR introduces VS Code-style zooming for the main query editor and database tree in the Qt Widgets GUI, including keyboard shortcuts, Ctrl+wheel gestures, and persistence of the zoom level as part of the window state.
Changes:
- Add
ZoomLevel(clamped step/scale value type) andZoomPresenter(applies zoom to registered widgets and handles Ctrl+wheel). - Add View menu actions (Zoom In/Out/Reset) and wire them to the presenter, including multi-shortcut handling for Zoom In.
- Persist zoom step between runs by extending
WindowStateand refactoringSettings::setMainWindowStateto take aWindowState.

before appending to targets, preserving its original basePointSize and avoiding
duplicate registrations. Ensure repeated calls after zooming do not capture the
scaled font or cause subsequent apply operations to scale the widget more than

Adds VS Code-style zoom to the query editor and the database tree.
What you can do
Why this shape
No QML is needed for this. Qt Widgets already propagates a widget's font to
the items it renders, so zooming is a matter of scaling the font on the two
target widgets and letting tree row heights and editor metrics follow.
The work splits along the usual seam:
ZoomLevel(src/gui/zoomlevel.h) is a clamped value type — steps of tenpercent, range 0.5x to 3.0x. No widgets, so it is tested directly.
ZoomPresenter(src/gui/zoompresenter.cpp) applies a level to the widgetsit is given, and turns Ctrl+wheel over them into steps.
Two details worth a reviewer's attention:
Widgets that start at different sizes stay proportional to each other, and
zooming in and back out returns to exactly the original size rather than
drifting through repeated multiplication.
amounts. Those are banked until they add up to a notch, so a light two-finger
scroll does not slam through the whole range in one gesture.
Also in here
Settings::setMainWindowStatenow takes aWindowStateinstead of sixpositional arguments. That refactor is its own commit, done before the seventh
field (the zoom step) was added.
One real bug was found and fixed during manual testing: registering
QKeySequence::ZoomInalongsideCtrl++on the same action puts the samesequence in the list twice on Windows, which Qt treats as an ambiguous overload
and answers by triggering nothing. See
drop the duplicate zoom shortcut sequences.Testing
pwsh -NoProfile -File build.ps1passes at every commit. Test count went from51 to 75.
Unit tests cover the level arithmetic and clamping, the font application
(including the no-drift property and targets destroyed out from under the
presenter), and the Ctrl+wheel filter including trackpad banking.
Verified in the running app by screenshot: the View menu renders, Ctrl+= scales
both the editor and the tree, and Ctrl+0 returns exactly to baseline.
Persistence was verified without keystrokes — seeding step 6 in the registry
started the app rendering at 1.6x, and a clean close wrote 6 back.
I did not get a reliable end-to-end "press keys, exit, re-read the setting"
run:
SendKeyskept failing to deliver to the window (it dropped a Ctrl+Q atone point). That is the automation harness being flaky rather than the app, but
it is worth one manual pass on the shortcuts before merging.
