Actually i wanna print color green on this Button.

But it didn't work, it still no color.

Can u try with style sheet for your requirements?

Doc says http://doc.qt.io/qt-4.8/qpalette.html#details

We strongly recommend that you use the default palette of the current style (returned by QApplication::palette()) and modify that as necessary. This is done by Qt's widgets when they are drawn.

To modify a color group you call the functions setColor() and setBrush(), depending on whether you want a pure color or a pixmap pattern.

Here is an example which may help you .

One more simple example is here .

Did you read the doc I posted?

A way by style sheet:

ui->pushButton->setStyleSheet("background:#CC892B;");

Yes, i assume that it means i have to change the code like this

ui->pushbuttonpt_land_resultlight->setpalette(QApplication::palette())

I'm not quite sure so i want to see the example to evidence my hypothesis.
Am i right?

Hi @victor-wang

To set the color of your pushbutton with qpalette you have to do something like this:

QPalette palette = ui->pushButton->palette();
palette.setColor(QPalette::Button,Qt::green);
ui->pushButton->setPalette(palette);

The result will be then similar to something like this:
alt text

If want change it to a custom color , you can use hex color code

palette.setColor(QPalette::Button,QColor("#FF0000")); // #FF0000 is for red color you can change it.

This should work for you,
