contentReady

void SWMM2DResultsQSGRenderer::contentReady ( )

signal

QSG-2D-1M Phase 7 — emitted when an asynchronous derived-geometry job (contour marching) publishes a result. MapCanvas connects this to its framebuffer-regrab path: without it, the freshly synced bands would sit in the offscreen QSG widget until the next layer-driven repaint.

Here is the caller graph for this function:

contentRevision()

quint64 SWMM2DResultsQSGRenderer::contentRevision ( ) const

inlinenoexcept

Monotonic counter bumped every time an external change marks this renderer's content dirty. MapCanvas compares it against the value recorded when it last grabbed the QSG framebuffer, so a change that arrives after the canvas cleared its own dirty flag still forces a regrab instead of compositing a stale frame. Extent and layer-pointer changes are keyed separately by the canvas and do not bump this.

forceRebuild()

void SWMM2DResultsQSGRenderer::forceRebuild

(

)

Drop caches and mark content dirty — used by MapCanvas when the QSG/CPU ownership toggles so a stale frame is never composited.
