Ravinder Singh sent me private mail saying that this thread had not provided a suitable solution to the satisfaction of the submitter and Ravinder. When I look at this thread, I see a very vague statement of the desired output and a sample script that doesn't work.

I note that vbe has already asked for a clarification of the requirements and no response has been provided. Without a clear statement of what output is desired (and sample output corresponding to the sample input [in CODE tags]), I don't see how anyone can provide any help.

Can there be alt-texts to icons?

Can you add hover texts (alt-texts) to icons? It is not always obvious what each of them mean just by looking at them. Sometimes it is clear from the url it points to, but for accessibility reasons alone it would be good to have alt-texts as a standard. (1 Reply)

NAME
QwtTextEngine - Abstract base class for rendering text strings. SYNOPSIS
#include <qwt_text_engine.h> Inherited by QwtMathMLTextEngine, QwtPlainTextEngine, and QwtRichTextEngine. Public Member Functions virtual void draw (QPainter *painter, const QRect &rect, int flags, const QString &text) const =0 virtual int heightForWidth (const QFont &font, int flags, const QString &text, int width) const =0 virtual bool mightRender (const QString &text) const =0 virtual void textMargins (const QFont &font, const QString &text, int &left, int &right, int &top, int &bottom) const =0 virtual QSize textSize (const QFont &font, int flags, const QString &text) const =0 virtual ~QwtTextEngine () Protected Member Functions QwtTextEngine () Detailed Description Abstract base class for rendering text strings. A text engine is responsible for rendering texts for a specific text format. They are used by QwtText to render a text. QwtPlainTextEngine and QwtRichTextEngine are part of the Qwt library. QwtMathMLTextEngine can be found in Qwt MathML extension, that needs the MathML renderer of the Qt solutions package. Unfortunately it is only available with a commercial Qt license. See also: QwtText::setTextEngine() Constructor &; Destructor Documentation QwtTextEngine::~QwtTextEngine () [virtual] Destructor. QwtTextEngine::QwtTextEngine () [protected] Constructor. Member Function Documentation virtual void QwtTextEngine::draw (QPainter *painter, const QRect &rect, intflags, const QString &text) const [pure virtual] Draw the text in a clipping rectangle Parameters: painter Painter rect Clipping rectangle flags Bitwise OR of the flags like in for QPainter::drawText text Text to be rendered Implemented in QwtPlainTextEngine, QwtRichTextEngine, and QwtMathMLTextEngine. virtual int QwtTextEngine::heightForWidth (const QFont &font, intflags, const QString &text, intwidth) const [pure virtual] Find the height for a given width Parameters: font Font of the text flags Bitwise OR of the flags used like in QPainter::drawText text Text to be rendered width Width Returns: Calculated height Implemented in QwtPlainTextEngine, QwtRichTextEngine, and QwtMathMLTextEngine. virtual bool QwtTextEngine::mightRender (const QString &text) const [pure virtual] Test if a string can be rendered by this text engine Parameters: text Text to be tested Returns: true, if it can be rendered Implemented in QwtPlainTextEngine, QwtRichTextEngine, and QwtMathMLTextEngine. virtual void QwtTextEngine::textMargins (const QFont &font, const QString &text, int &left, int &right, int &top, int &bottom) const [pure virtual] Return margins around the texts The textSize might include margins around the text, like QFontMetrics::descent. In situations where texts need to be aligend in detail, knowing these margins might improve the layout calculations. Parameters: font Font of the text text Text to be rendered left Return value for the left margin right Return value for the right margin top Return value for the top margin bottom Return value for the bottom margin Implemented in QwtPlainTextEngine, QwtRichTextEngine, and QwtMathMLTextEngine. virtual QSize QwtTextEngine::textSize (const QFont &font, intflags, const QString &text) const [pure virtual] Returns the size, that is needed to render text Parameters: font Font of the text flags Bitwise OR of the flags like in for QPainter::drawText text Text to be rendered Returns: Caluclated size Implemented in QwtPlainTextEngine, QwtRichTextEngine, and QwtMathMLTextEngine.
