GIMP doesn't accept file drop from Qt app

M Wong

GIMP doesn't accept file drop from my Qt apps in both Windows 10 and Linux (Xubuntu / Ubuntu 15.10). What format(s) should I add to the QMimeData?

Simplified app:
Click inside the red Rectangle and drag into a GIMP window, GIMP rejects the drag.

#include "win.h"

#include <QApplication>
#include <QDebug>
#include <QDrag>
#include <QMimeData>
#include <QMouseEvent>
#include <QPainter>

Win::Win()
    : QWidget(0)
{
    setFixedSize(300,300);
    m_rt = QRect(100,100,100,100);
}

void Win::mousePressEvent(QMouseEvent* e)
{
    if (m_rt.contains(e->pos())) {
        m_bDndOk = true;
        m_d = e->pos();
    }
    else m_bDndOk = false;
}

void Win::mouseMoveEvent(QMouseEvent* e)
{
    if (m_bDndOk && (e->pos() - m_d).manhattanLength() > qApp->startDragDistance()) {
        QList<QUrl> ls;
        ls << QUrl::fromLocalFile("F:\\tmp\\a.jpg");

        QMimeData* pData = new QMimeData;
        pData->setUrls(ls);

        QDrag* pDrag = new QDrag(this);
        pDrag->setMimeData(pData);
        pDrag->exec();
    }
}

void Win::mouseReleaseEvent(QMouseEvent* e)
{
    m_bDndOk = false;
}

void Win::paintEvent(QPaintEvent*)
{
    QPainter p(this);
    p.fillRect(m_rt, Qt::red);
}

Hi,

Might be related to QTBUG-45812

Which version of Qt are you using ?

M Wong

Thanks for your reply.

The following is from QtCreator's about box:

Qt Creator 3.6.1
Based on Qt 5.6.0 (MSVC 2013, 32 bit)

Built on Mar 14 2016 09:57:09

From revision d502727b2c

That's the information about Qt Creator itself. It has no relation with the Qt version you are currently using to build your application.

M Wong

The Qt installer I used is:

qt-opensource-windows-x86-msvc2015_64-5.6.0.exe

so I believe the Qt version is 5.6.0

The fix is stated for Qt 5.6.1 so currently you have two options to test it:

build Qt yourself from git
try with the 5.7 Beta.
