Detailed Description

The class for displaying formatted text with different properties.

This class allows displaying any given text with a properties set through the following methods:

setFontSize - sets the size of the font in points
setFontFamily - sets the family of the used font
setFontColor - sets the color of the displayed text
setBgColor - sets the background color of the widget
setDolarColor - sets the color of the highlighted text

Moreover the text can be formatted using the following control sequences:

[text] - the text within square brackets will be displayed in bold
{text} - the text in curly brackets will be displayed in italic
_text_ - the text between underscores will be displayed as underlined.
$text$ - the text between dolar signs will be displayed in a color specified with setDolarColor() function

The control sequences work as a mode switches, so the following text:

[Just] {a[n te}st] text.

will be displayed as:

Just an test text.

void QBigTextWidget::paintEvent (QPaintEvent *) [protected]

Overloaded from QWidget.

The painting of the text is where all the magic is done. In short: the text is split uzing whitespace and formatting delimiters and drawn token by token from the left edge of the widget to the right. If the token doesn't fit in the line it is drawn from the beginning of the next one.

BUG: The formatting delimiters are treaten as word delimiters and therefore a word may be split accross the lines if it contains formatting control sequences in the middle.

BUG2: The colouring information is lost at each new delimiter.
