I'm not completely sure what you mean. If you want to get the current position of the mouse cursor in coordinates relative the widget that displays your image then you can do this:

QPoint currentPosition = widget->mapFromGlobal( QCursor::pos() );

Thank you. It worked.

Hi,

this error usually means "The resource (qrc:/name of pic.jpg) is not specified in a .qrc file."
Probably, you need to look at Qt Resource System article.
Most likely it will help you.

Thank you.

I encountered the same issue, but since QtAssistant displays images without telling it where to find them, how does it manage to find them? It has to be somewhere in the qch file, right?

Hello @JKSH thanks for your response, I already solved the issue, the problem was in qml.qrc file, i just have to edit and update the file list with new icon images, then rebuild the project again.

Sounds more like a grid setup where one image is shown at a time.

If you do it with QLabel, you could have a 2 dimensional array holding your images e.g. QVector<QVector<QPixmap>> and a QPoint holding the current position in the array. So when you receive the gesture result e.g. swipe right you know that you can do point.x += 1and the put the QPixmap at that coordinate on the label.

I've figured this out. The problem wasn't in fact due to image files pixel alpha. That works just fine. It had to do with the QQuickView not being transparent. What I am doing is displaying a QQuickView as a borderless window to be used as a popup dialog and I want to see through to the background, where there are no objects in the qml file. (Think of a pop up dialog with rounded corners).

Here's what I'm doing:

QQuickView view; // don't display an icon in the task bar // no border on the window view.setFlags(Qt::SubWindow | Qt::FramelessWindowHint); // make the view transparent so that the edges of the window, // where there is no image, show through to the background QSurfaceFormat surfaceFormat; surfaceFormat.setAlphaBufferSize(8); view.setFormat(surfaceFormat); view.setClearBeforeRendering(true); view.setColor(QColor(Qt::transparent)); // load qml file and display view.setSource(file.qml); view.show();

Thank you mrjj ! that was it !

@SGaist That does sound like a viable way to do it, I am going to try that out, and let you guys know how it works.

Thanks!
