Description
When manually posting key events through QWindowSystemInterface::handleKeyEvent() shortcuts on macOS are no longer triggered in Qt 6.5.0 RC. Still works fine when using Qt 6.4.3.
Manual posting of key events is done by Squish for replaying key events during UI tests of Qt applications.
I attached an example project (shortcut.zip
), where there is a text field showing a counter that increases on the shortcut Ctrl+B (or rather Cmd+B on macOS). Pressing the key combination on a physical keyboard works fine in the two Qt versions mentioned above.
import QtQuick import QtQuick.Controls Window { visible: true title: "Shortcut" id: view property int seenShortcuts Shortcut { sequence: "Ctrl+B" onActivated: view.seenShortcuts++ } Text { text: view.seenShortcuts } Button { text: "Inject Shortcut" onClicked: injector.injectShortcut(view) } }
There is also a button that programmatically posts the key events, as Squish currently would. This works on Linux and Windows in Qt 6.4.3 and Qt 6.5.0 RC and still works on macOS in Qt 6.4.3 but stops working on macOS in Qt 6.5.0 RC.

"SUCCESS" : "FAILURE"); return result; } void ShortcutInjector::injectShortcut(QWindow *window) { qDebug() << "Injecting <Ctrl+B>"; postKeyEvent(window, QEvent::KeyPress, Qt::Key_Control, QFlags<Qt::KeyboardModifier>(Qt::KeyboardModifier::ControlModifier), ""); postKeyEvent(window, QEvent::KeyPress, Qt::Key_B, QFlags<Qt::KeyboardModifier>(Qt::KeyboardModifier::ControlModifier), ""); postKeyEvent(window, QEvent::KeyRelease, Qt::Key_B, QFlags<Qt::KeyboardModifier>(Qt::KeyboardModifier::ControlModifier), ""); postKeyEvent(window, QEvent::KeyRelease, Qt::Key_Control, QFlags<Qt::KeyboardModifier>(Qt::KeyboardModifier::NoModifier), ""); }
Note that SUCCESS and FAILURE are just the return value of the QWindowSystemInterface::handleKeyEvent() function and should be SUCCESS independent of the reported issue. The issue can be confirmed, if after clicking on Inject Shortcut the text still reads 0.
