<![CDATA[QGraphicsPixmapItem not showing when added to scene]]>My understanding is as follows:

I create a QGraphicsView, QGraphicsScene, and QPixmap.
The resource file allows me to customize the string for the file location. In this case, it's set to ":/piece/b_bishop.png" according to the documentation for resource files.
I create a QGraphicsPixmapItem using the QPixmap I created earlier.
I set the QGraphicsPixmapItem to the QGraphicsScene.
I set the scene to the view.
I show the view, but nothing happens.
Just to make sure, I changed the background color.

Below, I have my code.

#include <QApplication>
#include <QGraphicsScene>
#include <QGraphicsView>
#include <QGraphicsPixmapItem>
#include <QPixmap>
int main(int argc, char **argv)
{
    QApplication app (argc, argv);
    QGraphicsView view;
    QGraphicsScene scene;
    scene.setBackgroundBrush(Qt::green);
    
    QPixmap map (":/piece/b_bishop.png");
    QGraphicsPixmapItem bishop(map);
    scene.addItem(&bishop);

    view.setScene(&scene);
    view.show();

    return app.exec();
}

<RCC>
    <qresource prefix="/piece">
        <file>chesspieces/b_bishop.png</file>
    </qresource>
</RCC>

The image, as shown in the QT Creator:
1174bd28-43cb-422d-883b-8168344e3c78-image.png

I've currently tried: adjusting the syntax in multiple ways. By everything I have seen, I have done this correctly. I must be missing something. Thanks for your help.

?
Please check with QFile::exists() if your path is really correct.

I'm real dumb, I figured it out. Your solution worked, just had to keep digging. I had mixed up file names apparently.

Maybe a silly question but did you list your .qrc file in your .pro file ?

absolute path works.

I would much prefer not having to use absolute paths, though

Honestly I have no idea what that is, so probably not.

I just tried.

"QWidget: Cannot create a QWidget without QApplication"

I took your advice, and tried these:

QFile file1(":/piece/chesspieces/b_bishop.png");
QFile file2(":/piece/b_bishop.png");
QFile file3(":/chesspieces/b_bishop.png");

if(file1.exists())
    qDebug() << "file 1 exists";
else
    qDebug() << "file 1 does not exist";
if(file2.exists())
    qDebug() << "file 2 exists";
else
    qDebug() << "file 2 does not exist";
if(file3.exists())
    qDebug() << "file 3 exists";
else
    qDebug() << "file 3 does not exist";

None of them exist, assuming I wrote that code correctly to check lol.

Here is my file location:

0d64aafd-5070-4074-bb9c-564336f892d8-image.png

Ignore the other files, i'm just using main to test this.

I'm creating the resource file with the QT Creator, and adding files to it the same way.
