Backgroundcolor QLCDNumber in Windows?

[Teuniz]

I use a QLCDNumber and I changed the color of the background like this:

lCDNumber1 = new QLCDNumber(myobjectDialog);
  lCDNumber1->setGeometry(QRect(240, 810, 130, 40));
  lCDNumber1->setLineWidth(1);
  lCDNumber1->setSmallDecimalPoint(FALSE);
  lCDNumber1->setNumDigits(7);
  lCDNumber1->setSegmentStyle(QLCDNumber::Flat);
  lCDNumber1->setProperty("value", 0);
 
  lcdpalette = new QPalette;
  lcdpalette->setColor(QPalette::Background, QColor(170, 255, 0));
  lcdpalette->setColor(QPalette::Base, QColor(170, 255, 0));
  lcdpalette->setColor(QPalette::AlternateBase, QColor(170, 255, 0));
  lCDNumber1->setPalette(*lcdpalette);

lCDNumber1 = new QLCDNumber(myobjectDialog);
  lCDNumber1->setGeometry(QRect(240, 810, 130, 40));
  lCDNumber1->setLineWidth(1);
  lCDNumber1->setSmallDecimalPoint(FALSE);
  lCDNumber1->setNumDigits(7);
  lCDNumber1->setSegmentStyle(QLCDNumber::Flat);
  lCDNumber1->setProperty("value", 0);

  lcdpalette = new QPalette;
  lcdpalette->setColor(QPalette::Background, QColor(170, 255, 0));
  lcdpalette->setColor(QPalette::Base, QColor(170, 255, 0));
  lcdpalette->setColor(QPalette::AlternateBase, QColor(170, 255, 0));
  lCDNumber1->setPalette(*lcdpalette);

To copy to clipboard, switch view to plain text mode 

In Linux it works ok, but in Windows XP the backgroundcolor of the QLCDNumber
is lightgrey instead of green. I changed the style to Plastique with:

app.setStyle(new QPlastiqueStyle);

app.setStyle(new QPlastiqueStyle);

To copy to clipboard, switch view to plain text mode 

this changed the style to plastic in Windows XP but I still can not change the
backgroundcolor of QLCDNumber.

What do I need to do to get this working in Windows XP?

Have you tried?

lCDNumber1->setAutoFillBackground(true);

lCDNumber1->setAutoFillBackground(true);

To copy to clipboard, switch view to plain text mode 

[Teuniz]

lCDNumber1->setAutoFillBackground(true);

lCDNumber1->setAutoFillBackground(true);

To copy to clipboard, switch view to plain text mode 

does not work

mainwindow.cpp: In constructor ‘UI_Mainwindow::UI_Mainwindow()’:
mainwindow.cpp:246: error: ‘class QLCDNumber’ has no member named ‘setAutoFillBackground

Are you using Qt 4.0? The function was introduced in 4.1. I strongly suggest you to update to a recent version of Qt..

You are right, my QT version in Linux is 4.0 and it doesn't recognize this function.
I switched to Windows and now the fucntion is recognized because this version is 4.1.

Now the LCDNumber has the right backgroundcolor

Many thanks!
