Qt/C++ - Set background of disabled button? - c++

Question

I have all my buttons disabled in a grid, but for some, I'd like to change the background color. I'm trying:
_fieldButtons[0][0]->setStyleSheet("color: blue; background-color: blue;");
Where
QVector<QVector<QPushButton*> > _fieldButtons;
However, these buttons are all disabled, and only the text color gets changed:
How can I change the background, but not the text? Thank you!
UPDATE
I figured it's not working because the buttons are flat. How can I change flat button colors?

Answer 1

Two options:
Add border: none; to your stylesheet.
Use setAutoFillBackground(true) in conjunction with QPalette::Button
myButton->setFlat(true);
myButton->setAutoFillBackground(true);
QPalette pal = myButton->palette();
pal.setColor(QPalette::Button, QColor(Qt::blue));
myButton->setPalette(pal);

Answer 2

Try this:
myButton->setPalette(QColor("#124e6b"));
simply change the QColor to suit your use.
Or in Qt Creator you can right-click on the widget and select Change Style Sheet, as shown here:

Answer 3

Here you have two "Pseudo-States" in your control. For list of "Pseudo-States" refer below link.
http://doc.qt.io/qt-5/stylesheet-reference.html#list-of-pseudo-states
The first "Pseudo-State" is -- flat
The second "Pseudo-State" is -- disabled
Here you have to club both the states to set the style using "setStyleSheet".
_fieldButtons[0][0]->setStyleSheet(":flat:disabled {background-color: blue; border: none;}");
look for ":hover:enabled" (two different "Pseudo-States" how documentation handled) in the below link to get better idea.
http://doc.qt.io/qt-4.8/stylesheet-syntax.html
To understand, why you we have to give border:none for QPushButton, please look for below information in the first hyperlink in this answer.
"Warning: If you only set a background-color on a QPushButton, the background may not appear unless you set the border property to some value. This is because, by default, the QPushButton draws a native border which completely overlaps the background-color."
