QML DropArea: drop an external file does not work

Diego Donate

Hi,

I have a QML application and I would like to enable an area to drop there an external file (dragged from Windows explorer, for instance) and show the file path in my application.

I have a really simple test qml to try, but I can not drop anything ("not accepted" cursor is displayed when I enter my DropArea dragging the file).

My code:

import QtQuick 2.1
import QtQuick.Controls 1.0

ApplicationWindow {
    title: qsTr("Drop Area test")

    width: 800
    height: 600

    visible: true

    DropArea {
        id: drop
        anchors.fill: parent

        enabled: true

        onEntered:
            console.log("entered");

        onExited:
            console.log("exited")

        onDropped:
            console.log("dropped")
    }

    Text {
        id: textDrop
        anchors.centerIn: parent
        text: "Drop an element"
    }
}

I supponse I am doing anything wrong, but I can not fix it...

Thanks in advance

@Diego-Donate There was a bug reported but it is Linux specific. Looks like it was not solved for Windows. Which Qt version did you try ?

Diego Donate

@p3c0 I tried with QT 5.7

@Diego-Donate Well then you should report new one. And mention the OS and Qt version.

@p3c0 Have you tried my code? I thought it is so simple that it should work... I could not imagine it is a QT bug!! :(

@Diego-Donate You can try the official example:
http://doc.qt.io/qt-5/qtquick-externaldraganddrop-example.html

Try dropping external file into the second tile. If it succeeds it will display the file name.

It works on Ubuntu 14.04 with Qt 5.6

@p3c0 Ok, the example does not work for me in Windows 7 (QT 5.7)... I can drag and drop text from one tile to another inside the window, but nothing happens if i drag a file or text from out of the application...

I will notify it in case it is a bug... can it be??

@Diego-Donate According to me, yes, it is a bug.

@p3c0 The official example works for me when I drag and drop text from outside the application, but nothing happens when I try to drag a file, should it show the file name? Or it is only for text?

p3c0

@Diego-Donate

should it show the file name?

Yes.

Diego Donate

@p3c0 Thanks for your time. It seemed to be something related to my QT installation, I reinstalled QT package and now it works... I don't know why!!!

@Diego-Donate Glad to know that it works on Windows with Qt 5.7. Did you also check the official example ?

Diego Donate

@p3c0 Yes, it is the same, I am not sure why but now I have it all working... Thanks a lot
