How to display text and number on QLCDNumber class widget?

[thippu]

Hi,
I have mainwindow.cpp
In that I used QLCDNumber widget to display Number+Character.
I want dispaly current value+'v'.
But It does't display the characater 'v' what to do
code:

valx=new QLCDNumber(this);
   valx->setSegmentStyle(QLCDNumber::Flat);
   valx->setAutoFillBackground(true);
   valx->setFixedWidth(50);
   valx->setFixedHeight(25);
   valx->setFocusPolicy( Qt::WheelFocus );
   valx->setPalette(pal);

//signals used to connect to display 
connect(d_plot,SIGNAL( diffX(QString)),valx,SLOT(display(QString)));
   connect(d_plot,SIGNAL( diffY(QString)),valy,SLOT(display(QString)));

plot.cpp code:

//this methods are signalled to the mainwindow.cpp
 void Plot::calXY()
{
     QPointF x1p=d_origin4->value();
     QPointF x2p=d_origin3->value();
     QPointF y1p=d_origin->value();
     QPointF y2p=d_origin2->value();
     diffX(QString::number((((x1p.x()))-((x2p.x())))));
     diffY((QString::number((((y1p.y()))-((y2p.y())))+'v')));//here 'v' concatinated to value  of the LCD label, SO why its not working?
}

Hi,

QLCDNumber is designed to show numbers and only some letters as explained in the details of the class documentation. Therefore it might not be the best tool for your UI.

What does your v letter stand for ?

@SGaist v stands as Volts

Hi
its not using a font to draw the digits
so its impossible for it to draw a V.
You could just place a label close to it with the V.

Or use an U that's a common smybol for the voltage as well, QLCDNumber should be able to display an U

It could look like that :)

static const char *getSegments(char ch)
