That was a nice Tutorial… ::thumb up::

I try to add simple background image on Qwidget main object. it can display when I try to preview it (alt + shit + R), but..
I could not see the backgound image when I try to run build and ‘test’ running my application.

can you help me with this confusing?

Regards

And corresponding css:

#MainWindow {
background: #38395a;
}

#frame {
border: 1px solid gray;
border-radius: 7px;
background: QLinearGradient(x1: 0, y1: 0, x2: 0, y2: 1, stop: 0 #38395a, stop: 1 #141529);
}
QLabel {
font-size: 14px;
font-variant:small-caps;
font-family: courier;
color: white;
}

#label {
font-weight: bold;
font-size: 20px;
color: white;
}

QLineEdit {
padding: 1px;
border-style: solid;
border: 1px solid ;
color: white;
border-radius: 2px;
border-color: #141529;
background-color: #6d6d80;
}

QPushButton {
color: white;
background-color: QLinearGradient( x1: 0, y1: 0, x2: 0, y2: 1, stop: 0 #88d, stop: 0.1 #444450, stop: 0.49 #444450, stop: 0.5 #3c3c46, stop: 1 #1f1f24);
border-width: 1px;
border-color: #141529;
border-style: solid;
border-radius:4;
padding: 3px;
font-size: 14px;
font-variant:small-caps;
font-family: courier;
padding-left:5px;
padding-right: 5px;
min-width: 50px;
max-width: 50px;
min-height: 13px;
max-height: 13px;
}

You need to call this in C++:

myCheckBox->setObjectName(“myCheckBox”);

That’s how the style sheet system will identify the widget.

It works if the object name is set in code. Obviously this is not done automatically if building the user interface directly in C++.

myCheckBox ->setObjectName(“myCheckBox “);

I’m having similar problems as Linda (see 2010-02-01).

I use a global style sheet for my application and it works as it should if I use the Qt types like
QCheckBox {
spacing: 5px;
}

I don’t use the Qt Designer at all, building my user interface directly in C++. If I want to apply a style to a specified checkbox using its name, does not work. Do you have any idea? I’m using Qt 4.7.4.

#myCheckBox {
spacing: 5px;
}

myCheckBox = new QCheckBox(tr(“Hello World”));

I even tried to reload the style sheet immediately after the checkbox has been created, but this doesn’t succeed either.

Also, are you compiling your stylesheet using a .qrc file? That would explain why you have to recompile your application to get it to take effect.

this is for sure a reference tutorial, still now.

Nevertheless, I have spent hours to figure out why the mainfraime allways stay in white with no border. This is strange as when I copy paste your code in the “stylesheet” designe editor, this is fine. But at runtime the frame is rounded and white, no border.

If you have any idea, for my brain’s sake

PS : I also found that I need to do a “recompile” instead of compile to have changes applied from my outside stylesheet.
