class KWordWrap |
|
|
Word-wrap algorithm that takes into account beautifulness ;) That means: Usage: call the static method, formatText, with the text to wrap and the constraining rectangle etc., it will return an instance of KWordWrap containing internal data, result of the word-wrapping. From that instance you can retrieve the boundingRect, and invoke drawing. This design allows to call the word-wrap algorithm only when the text changes and not every time we want to know the bounding rect or draw the text.

Returns the bounding rect, calculated by formatText. The width is the width of the widest text line, and never wider than the rectangle given to formatText. The height is the text block. X and Y are always 0. |
|
Draws the string t at the given coordinates, if it does not fit into maxW the text will be faded out. p - the painter to use. Must have set the pen for the text color and the background for the color to fade out x - the horizontal position of the text y - the vertical position of the text maxW - the maximum width of the text (including the fade-out effect) t - the text to draw |
|
Draw the text that has been previously wrapped, at position x,y. Flags are for alignment, e.g. Qt.AlignHCenter. Default is Qt.AlignAuto. painter - the QPainter to use. x - the horizontal position of the text y - the vertical position of the text flags - the ORed text alignment flags from the Qt namespace, ORed with FadeOut if you want the text to fade out if it does not fit (the painter's background must be set accordingly) |
|
Draws the string t at the given coordinates, if it does not fit into maxW the text will be truncated. p - the painter to use x - the horizontal position of the text y - the vertical position of the text maxW - the maximum width of the text (including the '...') t - the text to draw |
|
Main method for wrapping text.
fm - Font metrics, for the chosen font. Better cache it, creating a QFontMetrics is expensive. r - Constraining rectangle. Only the width and height matter. With negative height the complete text will be rendered flags - currently unused str - The text to be wrapped. len - Length of text to wrap (default is -1 for all). Returns a KWordWrap instance. The caller is responsible for storing and deleting the result. |
|
Returns the original string, truncated to the first line. If dots was set, '...' is appended in case the string was truncated. Bug: Note that the '...' come out of the bounding rect. |
|
Returns the original string, with '\n' inserted where the text is broken by the wordwrap algorithm. |
