QRadioButton stylesheet font:bold doesn't work?

Sh1gs

By that thinking, then when the radiobutton is selected, the color shouldn't change, but it does. Changing it to : from :: didn't work either. I also tried ::unchecked to set the font weigh to normal and that didn't work :( I don't know what else to try. I've tried font, font-weight, font-style, and nothing seems to change the font to bold

Ultimately, I'm fiddling with stylesheets for a work project and would like to find a way to make this happen.

At this point you should get rid of any :checked etc. in the selector and just try an unconditional

"QRadioButton {" \
"font-weight:bold;" \
"}"

I imagine you will say this does not bold for you, and so we can eliminate anything about the :checked qualifier being of any relevance.

P.S.
Give a quick desperation try to font-weight:700;" instead of bold, just in case....

Hi
It seems the states checked unchecked do not use any font statements included.
alt text

They react fine to color change but any font statements seems to be ignored.
However, its does use its font inherited from QWidget as
targeting that, font is changed.
Also using RadioButton alone


QRadioButton {
font: 750 24pt "Arial";
}

So bascially im not sure its possible to make it go bold on checked using
stylesheets alone.

That is indeed how it was beginning to look. (Though I see some old web posts where users claim bold does work, some do not, various Qt versions.)

So you should try font-style: italic, and other individual font- styles, to verify just which style attribute(s) are affected. Before you check through the Qt source code (it's to do with font in QRadioButton, so it can't be hard to find) and raise a bug report depending on what you find :)

Using the unconditional, the text changes color AND gets bolded properly.

Reading through the Help files, QPushButton has the ability to customize the font. Both are box models, why do you think QRadioButton doesn't do it?

hi
well it does respond to font ,
but not in ::checked ::unchecked
as far as i could see from testing.
The states clearly work as the color was changed
but regardless of font statement used in those
states, i didn't see any effect even same font statement worked
with no state syntax.
So its either a bug, or simply not support for such states.

I did reference https://stackoverflow.com/questions/37802571/how-to-use-qss-to-set-radio-button-bold-when-checked above, which is exactly the situation you are reporting.

The "solution" there is only in a comment:

At the end, I use a property to indicate the font bold / normal and setProperty in the slot function. It worked! I wonder the difference between property and checked state

if you can figure what that OP means he did by this and it works for you.

@JonB said in QRadioButton stylesheet font:bold doesn't work?:

Probably this:

QRadioButton[checked="true"] {
   font-weight: bold;
}

additionally to that you could try:

connect( radioButton, &QRadioButton::toggled, this, [radioButton]() { 
    radioButton->style()->polish(radioButton);
} );

I do think the OP here should try just that.

However, the way the OP phrased what he wrote in the stackoverflow comment:

I use a property to indicate the font bold / normal and setProperty in the slot function.

might suggest he had to use a dynamic property (other than checked), which he added/removed or switched on/off in the stateChanged slot handler, to "shadow" the :checked state and get it to work with font change....
