class	::CrosshairOverlay

Detailed Description

QRhi-based GPU-accelerated channel time-series renderer used by the modern raw browser.

Manages its own pipeline, samplers, resource bindings and a small CrosshairOverlay for the time / amplitude cursor; exposes callbacks for the host ChannelDataView to push samples, change scaling or update the visible window.

◆ renderFrame()

void ChannelRhiView::renderFrame	(	QRhi *	rhi,
		QRhiRenderTarget *	target,
		QRhiCommandBuffer *	cb )

protected

Records one frame into target; render() calls it with the widget's own QRhi and render target.

Parameters

[in]	rhi	The QRhi that owns `target` and the view's GPU resources.
[in]	target	Render target sized like the widget times its device pixel ratio.
[in]	cb	Command buffer of the current frame.

Definition at line 1358 of file channelrhiview.cpp.

◆ renderToImage()

QImage ChannelRhiView::renderToImage ( const QSize & size = QSize() ) const

Render the current view (background bands, grid, annotations, traces, event and epoch markers) into an image with QPainter, without the GPU. Rows, scaling, butterfly layout, z-score mode and clipping highlight match the on-screen rendering, so this also works offscreen, e.g. for reports.

Parameters

[in] size Output size in pixels; the visible time span is stretched to fit. An invalid size (default) uses the widget size.

Returns: The rendered image (only the background if no channel is shown), or a null image if there is no model or the size is empty.

◆ scrollBy()

void ChannelRhiView::scrollBy	(	float	deltaSamples,

Definition at line 423 of file channelrhiview.h.

◆ setCrosshairEnabled()

void ChannelRhiView::setCrosshairEnabled ( bool enabled )

Enable or disable the crosshair cursor overlay. When enabled, a vertical + horizontal cross follows the mouse and the view continuously emits cursorDataChanged() with the time/amplitude under the cursor.

◆ setHideBadChannels()

void ChannelRhiView::setHideBadChannels ( bool hide )
