The QTextBlockFormat class provides formatting information for blocks of text in a QTextDocument.
A document is composed of a list of blocks, represented by QTextBlock objects. Each block can contain an item of some kind, such as a paragraph of text, a table, a list, or an image. Every block has an associated QTextBlockFormat that specifies its characteristics.
To cater for left-to-right and right-to-left languages you can set a block's direction with setDirection(). Paragraph alignment is set with setAlignment(). Margins are controlled by setTopMargin(), setBottomMargin(), setLeftMargin(), setRightMargin(). Overall indentation is set with setIndent(), the indentation of the first line with setTextIndent().
Line breaking can be enabled and disabled with setNonBreakableLines().
The brush used to paint the paragraph's background is set with setBackground(), and other aspects of the text's appearance can be customized by using the setProperty() function with the OutlinePen, ForegroundBrush, and BackgroundBrush QTextFormat::Property values.
If a text block is part of a list, it can also have a list format that is accessible with the listFormat() function.

Constructs a new QTextBlockFormat.
Returns the paragraph's alignment.
Смотрите также setAlignment().
Returns the paragraph's bottom margin.
See also setBottomMargin() and topMargin().
Returns the paragraph's indent.
See also setIndent().
Returns true if this block format is valid; otherwise returns false.
Returns the paragraph's left margin.
See also setLeftMargin(), rightMargin(), and indent().
Returns true if the lines in the paragraph are non-breakable; otherwise returns false.
See also setNonBreakableLines().
Returns the currently set page break policy for the paragraph. The default is QTextFormat::PageBreak_Auto.
Эта функция была введена в Qt 4.2.
See also setPageBreakPolicy().
Returns the paragraph's right margin.
See also setRightMargin() and leftMargin().
Sets the paragraph's alignment.
Смотрите также alignment().
Sets the paragraph's bottom margin.
See also bottomMargin(), setTopMargin(), setLeftMargin(), and setRightMargin().
Sets the paragraph's indentation. Margins are set independently of indentation with setLeftMargin() and setTextIndent(). The indentation is an integer that is multiplied with the document-wide standard indent, resulting in the actual indent of the paragraph.
See also indent() and QTextDocument::indentWidth().
Sets the paragraph's left margin. Indentation can be applied separately with setIndent().
See also leftMargin(), setRightMargin(), setTopMargin(), and setBottomMargin().
If b is true, the lines in the paragraph are treated as non-breakable; otherwise they are breakable.
See also nonBreakableLines().
Sets the page break policy for the paragraph to policy.
Эта функция была введена в Qt 4.2.
See also pageBreakPolicy().
Sets the paragraph's right margin.
See also rightMargin(), setLeftMargin(), setTopMargin(), and setBottomMargin().
Sets the tab positions for the text block to those specified by tabs.
Эта функция была введена в Qt 4.4.
See also tabPositions().
Sets the indent for the first line in the block. This allows the first line of a paragraph to be indented differently to the other lines, enhancing the readability of the text.
See also textIndent(), setLeftMargin(), setRightMargin(), setTopMargin(), and setBottomMargin().
Sets the paragraph's top margin.
See also topMargin(), setBottomMargin(), setLeftMargin(), and setRightMargin().
Returns a list of tab positions defined for the text block.
Эта функция была введена в Qt 4.4.
See also setTabPositions().
Returns the paragraph's text indent.
See also setTextIndent().
Returns the paragraph's top margin.
See also setTopMargin() and bottomMargin().
