Detailed DescriptionThe QAbstractTextDocumentLayout::PaintContext class is a convenience class defining the parameters used when painting a document's layout. A paint context is used when rendering custom layouts for QTextDocuments with the QAbstractTextDocumentLayout::draw() function. It is specified by a cursor position, default text color, clip rectangle and a collection of selections. See also QAbstractTextDocumentLayout. Member Variable DocumentationQRectF PaintContext::clipThis variable holds a hint to the layout specifying the area around paragraphs, frames or text require painting. Everything outside of this rectangle does not need to be painted. Specifying a clip rectangle can speed up drawing of large documents significantly. Note that the clip rectangle is in document coordinates (not in viewport coordinates). It is not a substitute for a clip region set on the painter but merely a hint. The default value is a null rectangle indicating everything needs to be painted. int PaintContext::cursorPositionThis variable holds the position within the document, where the cursor line should be drawn. The default value is -1. QPalette PaintContext::paletteThis variable holds the default color that is used for the text, when no color is specified. The default value is the application's default palette. QVector<Selection> PaintContext::selectionsThis variable holds the collection of selections that will be rendered when passing this paint context to QAbstractTextDocumentLayout's draw() function. The default value is an empty vector indicating no selection. X
