Constructor & Destructor Documentation

TimelineLabel()

TimelineLabel::TimelineLabel ( QWidget *  parent = 0 )

explicit

TimelineLabel empty constructor.

Parameters

parent

parent

Member Function Documentation

getFirstIndex()

uint TimelineLabel::getFirstIndex

(

)

getFirstIndex gets the index of the first diplayed frame

Returns

first index

getLastIndex()

uint TimelineLabel::getLastIndex

(

)

getLastIndexgets the index of the last diplayed frame

Returns

last index

indexToRelPos()

uint TimelineLabel::indexToRelPos

(

float

index

)

indexToRelPos returns the relative position which correspondes to the global index (firstIndex computation is involved in function)

Parameters

index

as a float number to also represent a position between two frames

Returns

relative position on the timelinelinelabel in pixels

mousePressEvent()

void TimelineLabel::mousePressEvent

(

QMouseEvent *

ev

)

mousePressEvent signals a mousepress event

Parameters

ev

the event

redraw()

void TimelineLabel::redraw

(

QPoint

boundaries = QPoint(-1, -1)

)

redraw redraws entire label

Parameters

(optional)

boundaries defines which frames are defined as out of bound and should be colored diffrent

relPosToIndex()

float TimelineLabel::relPosToIndex

(

int

relativePosition

)

relPosToIndex returns the respective index as float number to the relative position the timelinelabel

Parameters

relativePosition

on the timelinelinelabel in pixels

Returns

index as a float number to also represent a position between two frames

updateTimelinelabel()

void TimelineLabel::updateTimelinelabel	(	std::vector< uint > *	keyframes,
		QPointF	indexBounds,
		bool	drawTimestamps,
		QPoint	boundaries = QPoint(-1,-1)
	)

adjustTimeline sets atributtes and redraws TimelineLabel

Parameters

keyframes	new keayframes
indexBounds	represents the bounds of the timelinelabel in form of indices. They can be represented as floads so that the first and last displayed frame has an offset to its boundarie.
(optional)	boundaries defines which keyframelines will be outside of the bound and will color them diffrent
drawTimestamps	should timestamps be drawn
