Setting CSS width and height for QComboBox::drop-down and QComboBox::down-arrow

[the_]

Hi all,

I am trying to set the CSS for the dropdown and down-arrow but it seems to be ignored:
The QComboBox I am addressing has a QLineEdit and a QCompleter, so some users complain that the down-arrow is too small for them to hit it with fingers on the touch screen.

This is how it looks before applying the css

and after

#1206::down-arrow { width: 70px; height: 70px; }
#1206::drop-down { width: 70px; height: 70px; }

I get this

The style changes to somewhat ugly but the size is not set.
What is the proper way to set the width/height for it?
--EDIT
To add: the Style is set to Fusion with

QApplication a(argc, argv);
//...
a.setStyle(QStyleFactory::create("Fusion"));

in the main.cpp

Thanks in advance

why you not use stylesheet?

QComboBox[urgent = false] {color: black; border: 3px solid #5E749C;text-align: top;padding: 4px;border-radius: 7px; border-bottom-left-radius: 7px;background: white;width: 15px;height: 54px;}
QComboBox[urgent = true] {color: black; border: 3px solid #5E749C;text-align: top;padding: 4px;border-radius: 7px; border-bottom-left-radius: 7px;background:#19ff4f;width: 15px;height: 54px;}
QComboBox:drop-down {font-weight: bold;color: #5E749C; border: 3px solid #5E749C;border-radius: 4px;background: rgb(242, 242, 242, 150); background-color: qlineargradient(x1: 0, y1: 0, x2: 0, y2: 1,stop: 0 #FFFFFD, stop: 0.3 #96ADB2);width: 44px;  max-height: 44px;}
QComboBox:down-arrow {image: url(/home/st/Qt/B/C/res/downarrow.png); width: 24px; height: 24px;}

arrow size is related to QCombobox size ... but stylesheet can help you to break these link.

Thats exactly what I tried, I was able to change a lot of things but not the width of the down-arrow

@the_ hi, this should work:

QComboBox {
    border: 1px solid gray;
}

QComboBox::drop-down {
    width: 200px;
}

for whatever reason, you need to give the QComboBox a border or it won't accept the width for the drop-down....

@the_ if you try my code you can see the difference from yours ....
@J.Hilk you are in right ... I think it's because qt uses padding and border as selectors to switch from WM to custom .... is the same situation on all widget ...

@J.Hilk

The border does the trick, thanks
