Detailed Description

Generic base for hardware-accelerated waveform rendering.

Owns the audio buffer storage and visual properties. Subclasses provide the buffer data by calling setAudioBuffer(). Not registered to QML — use a derived class for QML usage.

Member Function Documentation

audioBuffer()

const juce::AudioSampleBuffer * zrythm::gui::qquick::WaveformCanvasItem::audioBuffer ( ) const

inline

Definition at line 40 of file waveform_canvas_item.h.

bufferGeneration()

uint64_t zrythm::gui::qquick::WaveformCanvasItem::bufferGeneration ( ) const

inline

Monotonically increasing counter bumped on each buffer change.

The renderer compares this against its own stored value to decide whether peak recomputation is needed — pure read-only access.

Definition at line 51 of file waveform_canvas_item.h.

notifyBufferChanged()

void zrythm::gui::qquick::WaveformCanvasItem::notifyBufferChanged ( )

protected

Bumps the generation counter and schedules a repaint.

Call after writing directly into audio_buffer_.
