Creates an invalid line.
Returns the line's ascent.
See also descent() and height().
Converts the cursor position cursorPos to the corresponding x position inside the line, taking account of the edge.
If cursorPos is not a valid cursor position, the nearest valid cursor position will be used instead, and cpos will be modified to point to this valid cursor position.
See also xToCursor().
This is an overloaded member function, provided for convenience.
Returns the line's descent.
See also ascent() and height().
Draws a line on the given painter at the specified position. The selection is reserved for internal use.
Returns the line's height. This is equal to ascent() + descent() + 1.
See also ascent() and descent().
Returns true if this text line is valid; otherwise returns false.
Returns the position of the line in the text engine.
Returns the rectangle covered by the line.
Returns the width of the line that is occupied by text. This is always <= to width(), and is the minimum width that could be used by layout() without changing the line break position.
Returns the line's position relative to the text layout's position.
See also setPosition().
Returns the line's bounding rectangle.
See also x(), y(), textLength(), and width().
Lays out the line with the given width. The line is filled from its starting position with as many characters as will fit into the line. In case the text cannot be split at the end of the line, it will be filled with additional characters to the next whitespace or end of the text.
Lays out the line. The line is filled from its starting position with as many characters as are specified by numColumns. In case the text cannot be split until numColumns characters, the line will be filled with as many characters to the next whitespace or end of the text.
This is an overloaded member function, provided for convenience.
Lays out the line. The line is filled from its starting position with as many characters as are specified by numColumns. In case the text cannot be split until numColumns characters, the line will be filled with as many characters to the next whitespace or end of the text. The provided alignmentWidth is used as reference width for alignment.
Moves the line to position pos.
See also position().
Returns the length of the text in the line.
See also naturalTextWidth().
Returns the start of the line from the beginning of the string passed to the QTextLayout.
Returns the line's width as specified by the layout() function.
See also naturalTextWidth(), x(), y(), textLength(), and rect().
Returns the line's x position.
See also rect(), y(), textLength(), and width().
Converts the x-coordinate x, to the nearest matching cursor position, depending on the cursor position type, cpos.
See also cursorToX().
Returns the line's y position.
See also x(), rect(), textLength(), and width().
