Detailed Description

QAbstractItemDelegate painting one FIFF channel's signal trace inside RtFiffRawView.

Transforms each visible row of the RtFiffRawViewModel into a polyline drawn inside the cell rectangle, applying the active y-scaling, SSP / compensation operators, trigger overlays and bad-channel greying.

Constructor & Destructor Documentation

RtFiffRawViewDelegate()

RtFiffRawViewDelegate::RtFiffRawViewDelegate

(

RtFiffRawView *

parent = 0

)

Creates a new abstract item delegate with the given parent.

Parameters

[in]

parent

Parent of the delegate.

Definition at line 49 of file rtfiffrawviewdelegate.cpp.

Member Function Documentation

getSignalColor()

QColor RtFiffRawViewDelegate::getSignalColor

(

)

Returns the signal color.

Returns

The current signal color.

Definition at line 326 of file rtfiffrawviewdelegate.cpp.

initPainterPaths()

void RtFiffRawViewDelegate::initPainterPaths

(

const QAbstractTableModel *

model

)

Initializes painter path variables to fit number of channels in the model/view.

Parameters

[in]

model

model.

Definition at line 61 of file rtfiffrawviewdelegate.cpp.

markerMoved()

void RtFiffRawViewDelegate::markerMoved	(	QPoint	position,
		int	activeRow )

markerMoved is called whenever user moves the mouse inside of the table view viewport

Parameters

[in]	position	The current mouse position.
[in]	activeRow	The current row which the mouse is moved over.

Definition at line 281 of file rtfiffrawviewdelegate.cpp.

paint()

void RtFiffRawViewDelegate::paint ( QPainter * painter, const QStyleOptionViewItem & option, const QModelIndex & index ) const

virtual

Use the painter and style option to render the item specified by the item index.

(sizeHint() must be implemented also)

Parameters

[in]	painter	Low-level painting on widgets and other paint devices.
[in]	option	Describes the parameters used to draw an item in a view widget.
[in]	index	Used to locate data in a data model.

Definition at line 92 of file rtfiffrawviewdelegate.cpp.

setSignalColor()

void RtFiffRawViewDelegate::setSignalColor

(

const QColor &

signalColor

)

Set the signal color.

Parameters

[in]

signalColor

The new signal color.

Definition at line 318 of file rtfiffrawviewdelegate.cpp.

setUpperItemIndex()

void RtFiffRawViewDelegate::setUpperItemIndex

(

int

iUpperItemIndex

)

Set the new upper item index color. This is used to only plot the background for the upper, visible item in the QTableView. This is a rather ugly hack in order to cope with QOpenGLWidget's/QtableView's problem when setting a background color.

Parameters

[in]

iUpperItemIndex

The new upper item index color.

Definition at line 333 of file rtfiffrawviewdelegate.cpp.

sizeHint()

QSize RtFiffRawViewDelegate::sizeHint ( const QStyleOptionViewItem & option, const QModelIndex & index ) const

virtual

Item size

Parameters

[in]	option	Describes the parameters used to draw an item in a view widget.
[in]	index	Used to locate data in a data model.

Returns

20 pixels wide by the row height for column 0, the option rectangle size otherwise.
