Detailed Description

Handles user interaction with a QwtScaleWidget.

This class is used by Graph to catch events for the scales on its Plot. ScalePicker doesn't take any actions beyond emitting signals, which are then processed by Graph.

Signals
void	axisDblClicked (int)
void	axisRightClicked (int)
void	axisTitleDblClicked ()
void	axisTitleRightClicked (int)
void	clicked ()
	Emitted when the user clicks on one of the monitored axes.
Public Member Functions
void	deselect ()
bool	labelsSelected ()
QwtPlot *	plot ()
	Return my parent casted to QwtPlot.
void	refresh ()
	ScalePicker (QwtPlot *plot)
QRect	scaleRect (const QwtScaleWidget *) const
	Returns the bounding rectangle of a scale without the title.
QRect	scaleTicksRect (const QwtScaleWidget *scale) const
	Returns the bounding rectangle of a scale excluding the title and the tick labels.
QwtScaleWidget *	selectedAxis ()
void	selectLabels (QwtScaleWidget *scale, bool select=true)
void	selectTitle (QwtScaleWidget *scale, bool select=true)
QRect	titleRect (const QwtScaleWidget *scale) const
	Returns the bounding rectangle of a scale's title.
bool	titleSelected ()

void ScalePicker::axisDblClicked

(

int

)

[signal]

Emitted when the user double-clicks on an axis (but not its title). The argument specifies the axis' QwtScaleDraw::Alignment.

void ScalePicker::axisRightClicked

(

int

)

[signal]

Emitted when the user right-clicks on an axis (but not its title). The argument specifies the axis' QwtScaleDraw::Alignment.

void ScalePicker::axisTitleDblClicked

(

)

[signal]

Emitted when the user double-clicks on an the axis title.

void ScalePicker::axisTitleRightClicked

(

int

)

[signal]

Emitted when the user right-clicks on the title of an axis. The argument specifies the axis' QwtScaleDraw::Alignment.

void ScalePicker::clicked

(

)

[signal]

Emitted when the user clicks on one of the monitored axes.
