Detailed Description

QML singleton providing imperative arranger object queries.

Thin wrapper over the pure C++ free functions in arrangement/arranger_object_all.h. Use this from imperative JS handlers (drag, resize). For reactive bindings, use TimelinePositionTracker.

Member Function Documentation

setEndFromTimelineTicks()

Q_INVOKABLE void zrythm::gui::qquick::ArrangerObjectHelper::setEndFromTimelineTicks ( structure::arrangement::ArrangerObject * obj, double timeline_end_ticks )

static

Sets an object's length so that its timeline end matches the given timeline tick position.

Reverse-warp converts the timeline end into content space before setting the length. No-op for objects without a length.

timelineEndTicks()

Q_INVOKABLE double zrythm::gui::qquick::ArrangerObjectHelper::timelineEndTicks ( structure::arrangement::ArrangerObject * obj )

static

Warp-aware absolute timeline end position.

For objects with a length, this is the warp-adjusted end. For objects without a length (e.g. Marker), returns the same as timelineTicks.

timelineTicks()

Q_INVOKABLE double zrythm::gui::qquick::ArrangerObjectHelper::timelineTicks ( structure::arrangement::ArrangerObject * obj )

static

Warp-aware absolute timeline position of an arranger object.

For clips and other timeline objects: returns the object's position. For child objects inside a clip (MidiNotes, etc.): converts through the parent clip's ContentTimeWarp.
