Change color of QLCD??

QFelix

Hello,
I want to change the color of the digits from QLCDNumber. How do I write this in Qt Creator?

Christian Ehrlicher

Set a QPalette with the colors you want. QLcdNumber is using the Light, Dark color role and the one set with QWidget::foregroundRole()

Hi
Welcome to the forums
As @Christian-Ehrlicher says, you can do that with QPalette like

// get the palette
auto palette = ui->lcdNumber->palette();
// foreground color
palette.setColor(palette.WindowText, Qt::blue);
// "light" border
palette.setColor(palette.Light, QColor(255, 0, 0));
// "dark" border
palette.setColor(palette.Dark, QColor(0, 255, 0));
// set the palette back
ui->lcdNumber->setPalette(palette);

However, it looks best if you change to flat look
ui->lcdNumber->setSegmentStyle(QLCDNumber::Flat );

Or matches the dark/light with the base color so the 'raised' look still works.

@mrjj What's the "ui" you're using? Can't find it in my code...

And another question: I wrote a program with some pictures and so on, it's a racing game. I wahr to include QLCDNumber in this program to Show the score, but it doesn't works...

If you create your code with Qt designer, you typically have a member ui in your class where you reference all your UI widgets. If you add them programmatically, then just ignore this ;)

Hi
How did yo use it ?
It should just work like any other widget you used.
But without some code , its hard to guess at what went wrong.
