Strange memory allocation in Qt for Android
Sources of clipboard for android:
@QMimeData *QAndroidPlatformClipboard::mimeData(QClipboard::Mode mode)
QMimeData *mimeData = new QMimeData(); mimeData->setText(QtAndroidClipboard::clipboardText()); return mimeData;
Is there a memory leak? On all other platforms that method returns pointer to class field.
m_androidPlatformClipboard = new QAndroidPlatformClipboard();
no sign of presence of this field anywhere else - neither in destructor, neither in function that returns clipboard:
@QPlatformClipboard *QAndroidPlatformIntegration::clipboard() const
static QAndroidPlatformClipboard *clipboard = 0;
clipboard = new QAndroidPlatformClipboard;
Am I novice, or are there memory leaks around?
Hi and welcome to devnet,
For the first point, it's not necessarily a bug, the handling might be done differently on Android. However I encourage you to ask this on the developer mailing list you'll find Qt's developers/maintainers there (this forum is more user oriented)
For the second point, indeed, the clipboard is allocated twice and not deleted in the destructor in the case of the member variable. A patch for that has been submitted.

Yep, I already commented "bugreport":https://bugreports.qt-project.org/browse/QTBUG-36025 existed previously.
