Member Function Documentation

◆ DoPlot()

void mpInfoLayer::DoPlot	(	wxDC &	dc,
		mpWindow &	w
	)

protectedvirtual

Plot method.

Can be overridden by derived classes.

Parameters

dc	the device content where to plot
w	the window to plot

See also: mpLayer::Plot

Implements MathPlot::mpLayer.

Reimplemented in MathPlot::mpInfoLegend, and MathPlot::mpInfoCoords.

◆ GetLocation()

mpLocation MathPlot::mpInfoLayer::GetLocation ( ) const

inline

Return the location of the mpInfoLayer box.

Returns: location

◆ GetPosition()

wxPoint MathPlot::mpInfoLayer::GetPosition ( ) const

inline

Returns the position of the upper left corner of the box (in pixels)

Returns: The rectangle position

◆ GetRectangle()

const wxRect& MathPlot::mpInfoLayer::GetRectangle ( ) const

inline

Returns the current rectangle coordinates.

Returns: The info layer rectangle

◆ GetSize()

wxSize MathPlot::mpInfoLayer::GetSize ( ) const

inline

Returns the size of the box (in pixels)

Returns: The rectangle size

◆ HasBBox()

virtual bool MathPlot::mpInfoLayer::HasBBox ( )

inlinevirtual

mpInfoLayer has not bounding box.

See also: mpLayer::HasBBox

Returns: always FALSE

Reimplemented from MathPlot::mpLayer.

◆ Inside()

bool mpInfoLayer::Inside ( const wxPoint & point )

virtual

Checks whether a point is inside the info box rectangle.

Parameters

point The point to be checked

Returns: true if the point is inside the bounding box

◆ Move()

void mpInfoLayer::Move ( wxPoint delta )

virtual

Moves the layer rectangle of given pixel deltas.

Parameters

delta The wxPoint container for delta coordinates along x and y. Units are in pixels.

◆ SetVisible()

void mpInfoLayer::SetVisible ( bool show )

virtual

Sets layer visibility.

Parameters

show	visibility bool.

Reimplemented from MathPlot::mpLayer.

◆ UpdateInfo()

void mpInfoLayer::UpdateInfo	(	mpWindow &	w,
		wxEvent &	event
	)

virtual

Updates the content of the info box.

Should be overridden by derived classes. Update may behave in different ways according to the type of event which called it.

Parameters

w	parent mpWindow from which to obtain informations
event	The event which called the update.

Reimplemented in MathPlot::mpInfoCoords.

◆ UpdateReference()

void mpInfoLayer::UpdateReference ( )

virtual

Updates the rectangle reference point.

Used by internal methods of mpWindow to correctly move mpInfoLayers.
