Detailed Description

This class implements additional QCanvasView functionality.

Attention: This class knows about QCanvasItem objects. Any methods that need to know about classes derived from QCanvasItem that are not part of Qt should be implemented in a derived class.

The original source code was taken from $QTDIR/examples/canvas/canvas.h of version 3.0 of Qt.

Bug:: @@@ Mac OS X only, printer margins not showing in correct place on the Canvas, however printing is working fine.

Requests:: Move any attached text displays along with moved plotter display.

Requests:: @@@ For plots using pixmap, do not draw plot when resizing until mouse is release.

Todo:: Need ability to group and un-group items.

Todo:: add page by adding another standard size page (either A4 or US Letter depending on preferences set somewhere.

Member Function Documentation

void add ( QCanvasItem * item )

Adds the item to the canvas.

Expands the canvas' size if necessary.

Referenced by CanvasView::addView(), CanvasView::groupView(), CanvasView::initFrom(), and CanvasView::ungroupView().

void addPage ( )

Adds a page to the canvas.

Referenced by CanvasWindow::viewAddPage().

void addPageMargin	(	int	x,
		int	y
	)

protected

Adds page margin.

Adds an indication of the page's margin. Only the contents inside the margin is printable.

void calcPrinterMetrics ( QPaintDevice * device )

protected

Calculate the size of a page by using the printer metrics.

The size of a printable page is calculated on the basis that one pixel will become one Postscript point. A QPaintDeviceMetrics object is created to find the actual and usable size of a page in millimeters which is then converted to Postscript Points.

Bug:: @@@ Talking the default printer at start-up causes large delays if printer is not available on the network.
