Is there a way to assign CSS style for the QTabBar close button?
Normally QTabBar can be styled, but I can't find its how button can be referenced from CSS.
As noted in a comment above, since Qt 4.6 you can use following style:
QTabBar::close-button {
image: url(close.png);
subcontrol-position: left;
}
It seems like there is not currently a way to style the close button via Qt style sheets. Not only is it not documented, there doesn't seem to be a style for it in src/gui/styles/qstylesheetstyle.cpp.
You can set the button using QTabBar::setTabButton() method.
You may want to submit it as a feature request on the Qt Bug Tracker.

Is there any solution to change the font color of QTableWidget's heads and items separately using Qt Designer? I want to make a complete design in Qt Designer without using code to set any styles
I wanted to add this as a comment but unfortunately my reputation is too low.
This should be possible by using a Stylesheet in the property editor. I can't test it right now but I assume it should look like these:
QTableWidget {
color: red;
}
QHeaderView {
color: blue;
}
Edit: I saw later that you asked without using code to set any styles. This is as far as I know not possible. But you can set the Style in property editor as I suggested, s.t. you can see the changes in the Qt Designer directly.
I want user to select a theme which he wants to apply to the document.
So i have created a popup dialog which has multiple themes which are qradiobutton. But I want to display only icons and remove circle from the widget.
I have tried visible:hidden for the radio button but that didn't worked.
If you want to customize QRadioButton with style-sheets I suggest you check the reference documentation: https://doc.qt.io/qt-5/stylesheet-reference.html#qradiobutton-widget
You should also find useful the examples given in Qt documentation as it shows how to replace the check indicator by different images:
QRadioButton::indicator {
width: 13px;
height: 13px;
}
QRadioButton::indicator::unchecked {
image: url(:/images/radiobutton_unchecked.png);
}
QRadioButton::indicator:unchecked:hover {
image: url(:/images/radiobutton_unchecked_hover.png);
}
https://doc.qt.io/qt-5/stylesheet-examples.html#customizing-qradiobutton
If you do this yo can just use the indicator to display the icon and leave the QRadioButton label empty.
However, I have to warn you, depending on which QStyle you are using, it could happen that using style-sheets destroys completely the style of a component. A general example is: you are using a style where buttons have round corners, you use style-sheets to change the font of the button and as a result the button does not have round corners anymore. This is caused by incompatibilities between some QStyle and the style-sheet mechanism. If you do not want to make a multi platform app, it might not be an issue as you will use only one style, but if you make an multi platform app, you have to check every possible style you platform can have on the different platforms.
So if you want to have a QRadioButton without indicator and not use style-sheets, you can do it in C++ directly by subclassing QAbstractButton. Just make sure you set your class to be autoExclusive so that is will behave like a radio button.
would you try this? ( visible => visibility )
input[type="radio"] {
visibility: hidden;
}
or
input[type="radio"] {
display: none;
}
I'm facing this problem when styling an editable QComboBox:
I'm unable to change the color of the grey box inside the QComboBox...
Any idea how to change it just with a stylesheet?
Thank you
What about
QComboBox:editable {
background: white;
}
? I did not test it, but the reference seems good to me.
Edit
As of using Qt version 5.6.2 the provided change works as desired. No differently colored box inside the currently edited QComboBox.
This shoud work
YourCombobox->findChild<QLineEdit*>()->setStyleSheet("QLineEdit {background: green;}");
Previous line get the reference to the QLineEdit which is part of the QComboBox widget and applies the style sheet to it, not to the combobox.
I don't know if this could also work, if you want to try it and give a feedback..
YourCombobox->setStyleSheet("QLineEdit {background: green;}");
I have a JavaFX button that has been set as Default Button so the user can select it with the Enter key. Currently, it has a blue background:
But I'd like to make it look like a normal button:
I took a look at the JavaFX CSS Guide and it looks like there's only one feature to override (-fx-base).
But changing this feature has unpredictable effects—sometimes it eliminates the button's gradient; sometimes it makes the button transparent.
Is there a simple way to just get rid of the Default Button styling?
My guess is that you are looking in the wrong style sheet. The old default style sheet caspian.css was replaced with modena.css. So setting default value for -fx-base from modena.css should fix the issue:
.button:default {
-fx-base: #ececec;
}
I'm trying to create a QPushButton that's just got an icon and a constant background color.
So that I can swap out the icon when the user clicks it, without any other apparent effects (this is for a roll-up/roll-down feature). I've added an entry like this to my stylesheet:
QPushButton.ToggleButton {
background-color: #8af;
}
and set the button's class to match, and this does indeed give me the look I want, except that when I click on it the background color changes to a lighter blue, which I don't want. What am I missing?
Edit: I guess I should mention I'm using Qt 4.5 and PyQt 4.6 to do this...
I know people like using stylesheets, but in this situation I think it is just as easy to make a custom button. Define a class that inherits from QAbstractButton, and override the paint() method. In the paint method, fill the rect with your desired background color, and then paint the current icon on top. It might be slightly more complicated if you want the border around the button as well, but not a lot.
Alternately, you could also look at the roles for QPalette, specifically QPalette::Light and QPalette::Midlight, which might be used to adjust the color of the button when pressed.
Answer
Try giving the button an ID with QObject::setObjectName and then applying the style with #idSelector?
In Python the code would probably look something like this:
button = QPushButton(self)
button.setObjectName("ToggleButton")
and stylesheet like this:
#ToggleButton:pressed {
background-color: #8af;
}

The QFriendFeed example application at Forum Nokia is using Qt style sheets heavily to customize the UI.
I'm guessing doing background-color: #8af !important; would be too obvious so I'm assuming that doesn't work. It's worth a try if you haven't done it yet.
Otherwise, as noted in this question, there are specific states you can style. Try setting the same background color for the pressed state:
QPushButton.ToggleButton:pressed { background-color: #8af; }
Sorry if I misunderstood. Hope that helps.
open the button's stylesheet in Qt designer and try this:
QPushButton:pressed {
image: url(/path/to/your/file/fileName.png);
}
