Detailed Description

Vertical column of channel-name labels synced with ChannelDataView row geometry.

Listens to the same ChannelDataModel as the central data view; bad channels are greyed and label clicks emit channel selection signals.

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 125 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 87 of file channellabelpanel.cpp.

setFirstVisibleChannel()

void ChannelLabelPanel::setFirstVisibleChannel

(

int

ch

)

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

Parameters

[in]

ch

Index of the first visible row in the displayed channel list.

Definition at line 95 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.

Parameters

[in]

hide

True to hide bad-channel rows.

Definition at line 115 of file channellabelpanel.cpp.

setModel()

void ChannelLabelPanel::setModel

(

ChannelDataModel *

model

)

Definition at line 79 of file channellabelpanel.cpp.

setVisibleChannelCount()

void ChannelLabelPanel::setVisibleChannelCount

(

int

count

)

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

Parameters

[in]

count

Number of simultaneously visible channel rows.

Definition at line 105 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.
