|
|
//! is able to print the text of a Scintilla document.

//! The class can be further sub-classed to alter to layout of the text, adding
|
|
//! headers and footers for example.

//! add customised text and graphics. \a drawing is true if the page is
|
|
//! actually being drawn rather than being sized. \a painter drawing
|
|
//! methods must only be called when \a drawing is true. \a area is the
|
|
//! area of the page that will be used to draw the text. This should be
|
|
//! modified if it is necessary to reserve space for any customised text or
|
|
//! graphics. By default the area is relative to the printable area of the
|
|
//! page. Use QPrinter::setFullPage() before calling printRange() if you
|
|
