Question

I am new to QT, I am facing some problems in inserting images to list view. This is my current code:

int main(int argc, char *argv[]) 
{
    QApplication a(argc, argv);

    QListWidget* list = new QListWidget();
    QListWidgetItem *item1 = new QListWidgetItem(QIcon(":\temp\boat.png"), "BlueHills", list);
    list->insertItem(0, item1);
    QListWidgetItem *item2 = new QListWidgetItem(QIcon("C:\\Documents and Settings\\admin\\Desktop\\icons\\car.png"), "Sunset", list);

    list->show();
}

The problem I have is only the text is being displayed.

How to insert image1

how to insert image2

Answer 1

I took your code and pasted it in a brand new QtCreator project and it works. I would suggest you double check your images’ paths.

The path for the image of your first item should be “:/temp/boat.png”. Make sure that your image is clearly defined in your resource file. I would therefore suggest you to test with an image located in the root of C, for instance "C://mypic.png".

You can add a resource file from within QtCreator using the New File or Project dialogue. The Qt Resource File is located under Files and Classes -> Qt

The resulting file may look something like this:

<RCC>
    <qresource prefix="images_section">
        <file alias="MyBoatImage">boat.png</file>
    </qresource>
</RCC>

If you choose to write it out, you need to add it your .pro file as such:

RESOURCES += resource.qrc

Whichever way you create the resource file, you can access its resources through something like: ":/images_section/MyBoatImage"
