Qt resources doesn't work in windows platform

adam_zhang

Hi Guys:
I met a problem. I compiled Qt 4.8.5 with MinGW 4.8.1. When I used an embeded resources in my project, I found that I can't use code like @ QPixmap pixmap(":/images/abc.jpg")@ to create a Pixmap. I know that pixmap already created but which's width() and height() is 0, and used same code in Linux, I found that it works.
I don't why it doesn't work in windows. And I don't how can I makt it worked.
Help me.

And if you try through a QLabel like this:
@
QLabel *label = new QLabel(this);
label->setPixmap(QPixmap(":/images/abc.jpg"));
@
Does it work?

Hi and welcome to devnet,

Since you compiled Qt yourself, are you sure the jpeg plugin was compiled ? (should be but one never knows)

You can get a list of known readable image format using:

@qDebug() << QImageReader::supportedImageFormats();@
