Returns: A ChartStyle type pointer to the display's style.

Note: The caller will not take ownership of the returned pointer.

void te::qt::widgets::ChartDisplay::selected	(	te::da::ObjectIdSet *	,
		const bool &
	)

signal

Emmit when objects were selected.

void te::qt::widgets::ChartDisplay::setPickerStyle ( int chartType )

It sets the QwtPlotPicker's state machine (selection mode)

Parameters

chartType The type of the chart that the picker will be adjusted to funtion for.

Although the selection function can work for any chart based on a single point (or click) some charts can benefit from a different behavior, such as a drag & release selection. This function will adjust the picker state machine to better suit the type of chart being displayed.

The current chart types supported and their respective selection mode are as follow:

te::qt::widgets::HISTOGRAM_CHART = Point selection; te::qt::widgets::SCATTER_CHART = Rectangle selection;

void te::qt::widgets::ChartDisplay::setSelectionColor ( QColor selColor )

color used to hgihlight selected objects on this display.

Parameters

selColor The color used to hgihlight selected objects on this display.

void te::qt::widgets::ChartDisplay::setStyle ( te::qt::widgets::ChartStyle * newStyle )

It sets the display's style.

Parameters

newStyle The new style.

Note: It will take ownership of the given pointer
