QPalette lcdpalette;
lcdNumber->setSegmentStyle( QLCDNumber::Filled );
lcdpalette.setColor(QPalette::WindowText, QColor( 170, 0, 0 ));
lcdNumber->setPalette( lcdpalette );

Experiment with QPalette::Light, QPalette::Dark and QPalette::Foreground,
instead of QPalette::WindowText.

In designer, change WindowText to the color you want.

Both within Designer and when directly modifying the palette, WindowText won't
work.
The LCD Number widget relies on: Light, Dark, Foreground.

i have a problem with LCDNumber change color, when i add lcdnumber in
MainWindow in Qt Designer (in layer and hboxLayaout). If i create LCDNumber
in MainWindow constructor i change color. But i need layout! :(

If I understand correctly, you're able to change colors within Qt Designer,
but not outside Qt Designer. It shouldn't be too difficult to change colors
outside of Qt Designer, just modify the palette as described here:
http://doc.trolltech.com/4.3/qpalette.html#details
Use the Light, Dark, Foreground color roles.
Now if you're creating a QLCDNumber within a widget in Qt Designer, you will
indeed probably need a layout. Why is this a problem?

no, i create LCDNumber within Qt Designer, but if i want change color within
my code.

If i create LCDNumber within Qt Designer and change color changing palette
within my code, the change failure; but if i do lcdNumber->setParent(this)
(within my MainWindow constructor) and after changing palette, the change is
ok, but obviously lose layout. This is the problem.

How do you change the palette?

I don't understand why you need to call lcdNumber->setParent(this). It's hard
to tell what could be going wrong without more details or some code.
