QPushbutton, background-color but flat ?

I've a QPushBUtton

i want to change the button color so i use a simple stylesheet

setStyleSheet("QPushButton { background-color: red; color: black;}");

The button is now red and text black, but it is became FLAT !!! So no, border and simple 3d effect like the standard button..

Why this ?

why? because that is what you told it to do. :confused:

For QPushButton, changing the background , you will need to change other properties as well.
Usually QPushButton paints according to the system theme. You will need to use some image with 3D effect for the button to look better.

Also there are ways to change colors of button using custom button.

My problem is that i have a simple panel with a button grey, with default qt style,
but if i simply change the background to make the button red, the button becomes red but it not seems to be a button because it becomes flat, it seems a text box !!

Code:

---

QPushButton* pb = new QPushButton("Test", this);
    pb->setStyleSheet(
       "QPushButton {"
            "margin: 1px;"
            "border-color: #0c457e;"
            "border-style: outset;"
            "border-radius: 3px;"
            "border-width: 1px;"
            "color: black;"
            "background-color: qlineargradient(x1: 0, y1: 0, x2: 0, y2: 1, stop: 0 #2198c0, stop: 1 #0d5ca6);"
        "}"
        "QPushButton:pressed {"
            "background-color: qlineargradient(x1: 0, y1: 0, x2: 0, y2: 1, stop: 0 #0d5ca6, stop: 1 #2198c0);"
        "}"
            );

Change what you want to what you want but general idea is that you have to style the button yourself from scratch.
