[SOLVED] QwtPlotTextLabel::setText(const QString&, QwtText::TextFormat) ?

[sirop]

Hallo.

I have a simple line:


plot->labelRpPlot->setText((const QString &) "Rp [N]=20000.333 <br><br> Rp[N/mm ²]=3.44455", QwtText::RichText);

but got errors:

..\AATORQUE_PLOTTIMER\mainwindow.cpp:767:135: error: no matching function for call to 'QwtPlotTextLabel::setText(const QString&, QwtText::TextFormat)'
plot->labelRpPlot->setText((const QString &) "Rp [N]=20000.333 <br><br> Rp[N/mm ²]=3.44455",QwtText::RichText);
^

..\..\LIB\qwt-6.1.2\include/qwt_plot_textlabel.h:55:10: note: void QwtPlotTextLabel::setText(const QwtText&)
void setText( const QwtText & );

Why? The documentation for 6.1.2 does offer:

void QwtTextLabel::setText ( const QString & text,
QwtText::TextFormat textFormat = QwtText::AutoText
)

Thanks for all your answers in advance.

I do not get it yet.

Now used your proposal:


plot->labelRpPlot->setText(QString ( "Rp [N]=20000.333 <br><br> Rp[N/mm ²]=3.44455" ), QwtText::RichText);

Compiler output:

..\AATORQUE_PLOTTIMER\mainwindow.cpp:816:126: error: no matching function for call to 'QwtPlotTextLabel::setText(QString, QwtText::TextFormat)'
plot->labelRpPlot->setText(QString("Rp [N]=20000.333 <br><br> Rp[N/mm ²]=3.44455"),QwtText::RichText);

void setText( const QwtText & );

I use mingw 4.9.2 32 bit dw without unicode support.

Ah yes: QwtTextLabel != QwtPlotTextLabel ( re-read your initial question ! ):

So your line should be:

plot->labelRpPlot->setText( QwtText( "Rp [N]=20000.333 <br><br> Rp[N/mm ²]=3.44455" , QwtText::RichText ) );or:

plot->labelRpPlot->setText( QwtText( QString( "Rp [N]=20000.333 <br><br> Rp[N/mm ²]=3.44455" ), QwtText::RichText ) );Uwe
