Detailed Description

Fixed-width panel showing channel names and metadata, left of the render surface.

Repaints one row per visible channel (height / visibleChannelCount pixels each). Each row shows: a type-colour strip, channel name, type abbreviation, and a red "BAD" badge when the channel is flagged bad. Hovering over a row shows a tooltip with full detail.

Vertical drag on the panel scrolls the channel window (emits channelScrollRequested).

Member Function Documentation

channelBadToggled

void DISPLIB::ChannelLabelPanel::channelBadToggled ( int channelIndex, bool bad )

signal

channelScrollRequested

void DISPLIB::ChannelLabelPanel::channelScrollRequested ( int targetFirst )

signal

Emitted while the user drags vertically on the panel.

Parameters

[in]

targetFirst

The desired new first-visible-channel index.

setButterflyMode()

void ChannelLabelPanel::setButterflyMode

(

bool

enabled

)

Enable or disable butterfly mode. When active, lanes show type group labels (e.g. "MEG", "EEG") instead of individual channel names.

Parameters

[in]

enabled

true = butterfly mode, false = normal per-channel mode.

Definition at line 147 of file channellabelpanel.cpp.

setChannelIndices()

void ChannelLabelPanel::setChannelIndices

(

const QVector< int > &

indices

)

Restrict the panel to a subset of model channel indices. When indices is empty all model channels are available (no filter). Must be kept in sync with ChannelRhiView::setChannelIndices().

Parameters

[in]

indices

Ordered list of model channel indices to display.

Definition at line 109 of file channellabelpanel.cpp.

setFirstVisibleChannel()

void ChannelLabelPanel::setFirstVisibleChannel

(

int

ch

)

Set the index of the first visible channel row (kept in sync with ChannelRhiView).

Definition at line 117 of file channellabelpanel.cpp.

setHideBadChannels()

void ChannelLabelPanel::setHideBadChannels

(

bool

hide

)

Show or hide bad-channel rows. When hide is true, bad channels are removed from the visible row list so the panel stays aligned with the trace view.

Definition at line 137 of file channellabelpanel.cpp.

setModel()

void ChannelLabelPanel::setModel

(

ChannelDataModel *

model

)

Definition at line 101 of file channellabelpanel.cpp.

setVisibleChannelCount()

void ChannelLabelPanel::setVisibleChannelCount

(

int

count

)

Set how many channel rows are simultaneously visible (kept in sync with ChannelRhiView).

Definition at line 127 of file channellabelpanel.cpp.

setVisibleSampleRange()

void ChannelLabelPanel::setVisibleSampleRange	(	int	firstSample,
		int	lastSample )

Update the visible sample window used for the per-channel RMS level bar. Call this whenever the horizontal scroll position changes.

Parameters

[in]	firstSample	Absolute first sample in the visible window.
[in]	lastSample	Absolute last sample (exclusive) in the visible window.
