Constructor & Destructor Documentation

MultiPlot	(	int	plots,
		int	columns,
		bool	horizontal,
		Plot::KeepMode	keep = `Plot::Copy`,
		QWidget *	parent = `0`
	)

Constructs plots plots with KeepMode keep. If you set keep to Plot::Pointer and you are using multible threads, then you need to provide a mutex for locking the data via setDataMutex().

MultiPlot	(	int	plots,
		int	columns,
		bool	horizontal = `true`,
		QWidget *	parent = `0`
	)

Constructs plots plots.

Member Function Documentation

void lock ( void )

Lock the plot mutex.

Referenced by Plot::mouseAnalyse(), Plot::mouseSelect(), Plot::mouseSetCursor(), Plot::mouseZoomMoveFirstX(), Plot::mouseZoomMoveFirstY(), and Plot::mouseZoomMovePlot().

bool tryLock ( int timeoutms = 1 )

Try to lock the plot mutex for at maximum timeoutms milliseconds.

void unlock ( void )

Unlock the plot mutex.

Referenced by Plot::mouseAnalyse(), Plot::mouseSelect(), Plot::mouseSetCursor(), Plot::mouseZoomMoveFirstX(), Plot::mouseZoomMoveFirstY(), and Plot::mouseZoomMovePlot().

void setDataMutex ( QMutex * mutex )

Provide a mutex for all subplots that is used to lock access to all data while they are plotted. If you want to change the mutex, you first have to disable the mutex by calling clearDataMutex().

See Also: setDataMutex(QReadWriteLock*)

Referenced by MultiPlot::setDataMutex().

void setDataMutex ( QReadWriteLock * mutex )

Provide a mutex for all subplots that is used to lock reading access to all data while they are plotted. If you want to change the mutex, you first have to disable the mutex by calling clearDataMutex().

See Also: setDataMutex(QMutex*)

References MultiPlot::setDataMutex().

void clearDataMutex ( void )

Disables the data mutex and the data mutexes of the subplots.

See Also: setDataMutex()

int size ( void ) const

The number of Plots in the MultiPlot widget.

Referenced by MultiPlot::doResize().

bool empty ( void ) const

True if there isn't any Plot in the MultiPlot widget.

void resize	(	int	plots,
		Plot::KeepMode	keep = `Plot::Copy`
	)

Change the number of plots to plots. The zoom-stacks of all plots are reset (Plot::resetRanges() ) and the common X and Y ranges are cleared.

Note: the plot mutex must be locked ( lock() ), when calling this function!

References MultiPlot::doResize().

Referenced by MultiPlot::resize().

void resize	(	int	plots,
		int	columns,
		bool	horizontal,
		Plot::KeepMode	keep = `Plot::Copy`
	)

Change the number of plots to plots and update the layout. The zoom-stacks of all plots are reset (Plot::resetRanges() ) and the common X and Y ranges are cleared.

Note: the plot mutex must be locked ( lock() ), when calling this function!

References MultiPlot::layout(), and MultiPlot::resize().

void clear ( void )

Remove all Plots from the MultiPlot widget.

Note: the plot mutex must be locked ( lock() ), when calling this function!

References MultiPlot::doClear().

Referenced by MultiPlot::~MultiPlot().

void erase ( int index )

Remove Plot number index from the MultiPlot widget.

Note: the plot mutex must be locked ( lock() ), when calling this function!

References MultiPlot::doErase().

Plot& operator[] ( int i )

inline

The Plot-widget i.

Plot& back ( void )

inline

The last Plot in the list.

Plot& front ( void )

inline

The first Plot in the list.

void layout	(	int	columns,
		bool	horizontal = `true`
	)

QSize sizeHint ( void ) const

virtual

Give a hint for the prefered size of this widget.

References relacs::ceil().

QSize minimumSizeHint ( void ) const

virtual

Give a hint for the minimum size of this widget.

References relacs::ceil().

void draw ( void )

Draw the Plots.

Referenced by Plot::draw().

void setDrawBackground ( void )

To be called from a Plot to request to redraw the background.

Referenced by Plot::setOrigin(), and Plot::setSize().

void clearPlots ( void )

Clear each Plot from data, i.e. call Plot::clear() for each Plot.

void enableMouse ( void )

Enable mouse support for all subplots.

void disableMouse ( void )

Disable mouse support for all subplots.

void changedRanges ( int id )

signal

Ranges of some plots have been changed due to a change in plot id. The plot range was changed by the user. Both the MultiPlot mutex and the mutex of the Plot that initiated the changed ranges are locked.

Referenced by MultiPlot::setRanges().

void resizePlots ( QResizeEvent * qre )

signal

This signal is emitted whenever the MultiPlot widget receives a resizeEvent() before processing it. Can be used to change e.g. the origin and size of the plots.

Referenced by MultiPlot::resizeEvent().

void popRanges ( void )

slot

Set the ranges of all stacks according to the last zoom-stack entry and remove it from the stack.

void resetRanges ( void )

slot

Clears the zoom stack of all plots.

void paintEvent ( QPaintEvent * qpe )

protected

Paints the entire plot.
