QPushButton StyleSheet bug ?

ksubox

Hello,
I have following code:

const char *cHeadButtonStyle = "QPushButton#btFriends { background-color: green; }";
m_btTabMyFriends = new QPushButton(tr("btFriends"), this);
m_btTabMyFriends->setObjectName("btFriends");
m_btTabMyFriends->setStyleSheet(cHeadButtonStyle);

But stylesheet doesn't work at all whatever I try.

This code works:
m_btTabMyFriends = new QPushButton(tr("btFriends"), this);
m_btTabMyFriends->setObjectName("btFriends");
m_btTabMyFriends->setStyleSheet("background-color: green;");

And this one also works:
m_btTabMyFriends = new QPushButton(tr("btFriends"), this);
m_btTabMyFriends->setObjectName("btFriends");
m_btTabMyFriends->setStyleSheet("QPushButton { background-color: green; }");

But this one doesn't:
m_btTabMyFriends = new QPushButton(tr("btFriends"), this);
m_btTabMyFriends->setObjectName("btFriends");
m_btTabMyFriends->setStyleSheet("QPushButton#btFriends { background-color: green; }");

Is this bug in QT 5.4 related to ID selectors ?

Try this :

@m_btTabMyFriends->style()->polish(m_btTabMyFriends);@

just testet your code in a simple program and it worked for me.
@int main(int argc, char *argv[])
{
QApplication a(argc, argv);

QWidget w;
const char *cHeadButtonStyle = "QPushButton#btFriends { background-color: green; }";
QPushButton* m_btTabMyFriends = new QPushButton("btFriends", &w);
m_btTabMyFriends->setObjectName("btFriends");
m_btTabMyFriends->setStyleSheet(cHeadButtonStyle);


QPushButton* m_btTabMyFriends2 = new QPushButton("btFriends", &w);
m_btTabMyFriends2->setStyleSheet("QPushButton { background-color: red; }");

QHBoxLayout* lyout = new QHBoxLayout(&w);
lyout->addWidget(m_btTabMyFriends);
lyout->addWidget(m_btTabMyFriends2);


w.show();

return a.exec&#40;&#41;;

}@

I think the problem is not in that lines.
Do you set stylesheet anywhere else ?

Yes, your code works. But mine - doesn't.
I temporary commented out all setStyleSheet(... except one and anyway doesn't work.
What is different - I have children widgets:
main window -> children QWidget with buttons (works well) and -> children QWidget with buttons (this buttons don't work)
If I copy button code from inner QWidget that code works well in parent QWidget.

What could it be ?

Could you try to to set one global stylesheet on your centralWidget of you main window ?
And remove all other setStylesheet declarations.

That is what i did in my Application and it works.
