virtual void DtQtDrawer::drawPixmap ( const DtDisplayPoint &  pt, const QPixmap &  p, int  transparencyLevel = 0  )

virtual

Implements DtPrimitiveDrawer.

virtual void DtQtDrawer::drawImage ( const DtDisplayPoint &  pt, const QImage &  p, bool  blend = true, int  transparencyLevel = 0  )

virtual

This call differs from drawPixmap in that if the supplied image contains an alpha mask, it will blend the image with the current background image using that mask.

If you do not need this type of blending, use the drawPixmap call to simply use the monochrome bitmap (if it exists).

Transparency level is set from 0 to 100. This will override any alpha channel or blend flag, as, if non-zero, will pick that as the percent of pixel to display (0 being opaque, 1 being completely transparent)

Implements DtPrimitiveDrawer.

virtual void DtQtDrawer::clear ( )

virtual

erase with fillcolor

Implements DtPrimitiveDrawer.

virtual void DtQtDrawer::labelForHorizLine ( const DtDisplayPoint &  pt, const char *  pString  )

virtual

clientWnd() and setClientWnd() used to get/set the window which will be drawn upon call this before calling

Grid line stuff.

Implements DtPrimitiveDrawer.

virtual void DtQtDrawer::labelForVertiLine ( const DtDisplayPoint &  pt, const char *  pString  )

virtual

Implements DtPrimitiveDrawer.

virtual void DtQtDrawer::internalDrawImage ( int  x, int  y, const QImage &  image  )

virtual

Because all Qt does internally is convert images to pixmaps before drawing, for very large images, this does not work.

Here will will pick and image size and draw "slices" of the image if the image is too large to draw
