Rich + text editing is fairly limited. You can't set margins or + insert images for example (although you can read and + correctly display files that have margins set and that + include images). This mode is mostly useful for editing small + amounts of rich text. <sup>2.</sup> + \row \i Text Viewer<sup>3.</sup> \i setReadOnly(TRUE) + \i Set text with setText() or append() (which has no undo + history so is faster and uses less memory); text() returns + plain or rich text depending on the textFormat().

QTextEdit works on paragraphs and characters. A paragraph is a formatted string which is word-wrapped to fit into the width of - the widget. A document consists of zero or more paragraphs, - indexed from 0. Characters are indexed on a per-paragraph basis, - also indexed from 0.
