//! \brief The TQextScintillaPrinter class is a sub-class of the TQt TQPrinter
|
|
//! class that 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.

|
|
//! 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
|
|
//! TQPrinter::setFullPage() because calling printRange() if you want to
|
|
//! try and print over the whole page. \a pagenr is the number of the
