Style for custom QWidget

sting

With this code it doesn't work for QWidget and it does for QGroupBox. The other stylesheets I use that work are for QGroupBox. For QGroupBox I use the border section and the QGroupBox::title selector.

This code is working fine here. Can you post all your style sheets ?

sting

I have changed everything to use QGroupBox temporarily and it seems to work. I wonder if it is a problem with my environment. I am using ubunto linux as a host. It supprised me that that simple of an application caused the issue to show.

Does it also happen if you set this style sheet on a default project ? Just create a new one using a QDialog as base class and set the style sheet on it

sting

I made the dialog example and I think I found the following:

If I use a plain QWidget the stylesheets work fine.

If I use a custom widget that inherits from QWidget the style sheets do not work.

If I use a custom widget that inherits from QGroupBox it does work. Just the same as my other example.

@
Dialog::Dialog(QWidget *parent)
: QDialog(parent) {
QVBoxLayout *mainLayout = new QVBoxLayout;
setLayout(mainLayout);
//QWidget *widget = new QWidget(this);
//QGroupBox *widget = new QGroupBox(this);
ToneWidget *widget = new ToneWidget(this);
widget->setFixedWidth(100);
widget->setFixedHeight(100);
//widget->setObjectName("Foo");
//widget->setStyleSheet("QWidget#Foo {border: 2px solid red; border-radius: 2px}");
//widget->setStyleSheet("QGroupBox#Foo {border: 2px solid red; border-radius: 2px}");
// Try to set it externally
//widget->setStyleSheet("ToneWidget#Foo {border: 2px solid red; border-radius: 2px}");
mainLayout->addWidget(widget);
}
@

@
class ToneWidget : public QWidget
//class ToneWidget : public QGroupBox
{
Q_OBJECT
public:
ToneWidget(QWidget* parent = 0);
};
@

@
ToneWidget::ToneWidget(QWidget* parent) : QWidget(parent)
//ToneWidget::ToneWidget(QWidget* parent) : QGroupBox(parent)
{
setFixedWidth(100);
setFixedHeight(100);

setObjectName("bar");
setStyleSheet("QWidget#bar {border: 2px solid red; border-radius: 2px}");
//setStyleSheet("QGroupBox#bar {border: 2px solid red; border-radius: 2px}");
//setStyleSheet("ToneWidget#bar {border: 2px solid red; border-radius: 2px}");

}

Which OS are you running on ? I can't make it fail here

sting

I am using ubuntu the latest 64 bit version. 14.3 or 14.4 I will check again when I get home.

sting

I will take it to work tomorrow and try it on a windows machine. I will be depressed if it works on windows and not on linux.

"From the Qt 5 documentation"http://qt-project.org/doc/qt-5/stylesheet-reference.html

QWidget Supports only the background, background-clip and background-origin properties.

I should have read this a long time ago. Sorry to waste your time.

SGaist

Which one were you trying to use ?

sting

setStyleSheet("QWidget {border: 2px solid red; border-radius: 2px}");

SGaist

This one should be working

I just did the same experiment on a Windows machine with Qt Creator 3.1.2
Based on Qt 5.3.1 (MSVC 2010, 32 bit) with the same device. If I take any QWidget and apply the above stylesheet and it doesn't work. If I change the QWidget to a QGroupBox with the appropriate change in the stylesheet the border does show.

I have just changed all of the QWidgets that I need a border around to QGroupBox for now. Should I mark this thread closed?
