� work more efficiently by treating text and graphics separately so that, for instance, all
text is covered in one band, while graphics are covered in several small bands.
As the implementer of PrintBandL(), you clearly have to honor the page number, so that
you print the relevant text on every page.
Whether you take any notice of the band attributes is rather like whether you take any notice
of the bounding rectangle passed to CCoeControl::Draw(): if you ignore these
parameters, your code may work fine. But you may be able to substantially speed printing up
by printing only what's necessary for each band.
Anyway, you could reuse the view code in CExampleHelloView to implement
PrintBandL() for a single-page print:
void CMyApplication::PrintBandL(CGraphicsDevice* aDevice,
aBandInPixels */)
{
//Allocate the font
TInt /* aPageNo */
TFontSpec fontSpec(_L("Arial"), 6*10);
const TBandAttributes& /*
fontSpec.iFontStyle=TFontStyle(EPostureUpright,
EStrokeWeightBold,
EPrintPosNormal);
CFont* font;
User::LeaveIfError(aDevice.GetNearestFontInTwips(font,
fontSpec));
//Draw the view
CGraphicsContext* gc;
User::LeaveIfError(aDevice->CreateContext(gc));
TRect rectInTwips(2880, 2880, 2880, 1440):
TRect rect(aDevice->HorizontalTwipsToPixels(rectInTwips.iTl.iX),
aDevice->VerticalTwipsToPixels(rectInTwips.iTl.iY),
aDevice->HorizontalTwipsToPixels(rectInTwips.iBr.iX),
aDevice->VerticalTwipsToPixels(rectInTwips.iBr.iY));
iView->DrawInRect(*aDevice, *gc, rect, font);
delete gc;
//Release the font
aDevice.ReleaseFont(font);
}
Because PrintBandL(~) is a leave function, we are able to allocate the font within it.
This prints the text in a rectangle 2 × 1 inches big, whose top-left corner is 2 inches down, 2
inches right, from the edge of the paper – regardless of paper size and margins. More
