Re: [Development] Windows plugin customisation: QWindowsKeyMapper
I actually also tried this to no avail. Is it a Windows plugin or native
event filter bug that I cannot intercept alt+key presses? Or am I doing
something wrong?
#include
#include
#include
#include
#ifdef Q_OS_WIN
#include
#endif
class MyMSGEventFilter : public QAbstractNativeEventFilter
{
public:
bool nativeEventFilter(const QByteArray &eventType, [[maybe_unused]]
void *message, long *) override
{
#ifdef Q_OS_WIN
if (eventType == "windows_generic_MSG"
|| eventType == "windows_dispatcher_MSG") {
MSG *msg = static_cast(message);
// This works
if (msg->wParam == VK_SPACE) {
std::cout << "TEST SPACE" << std::endl;
}
// None of these work.
// else if (msg->wParam == WM_SYSKEYDOWN) {
// else if (msg->wParam == VK_MENU) {
else if (msg->wParam == VK_LMENU) {
std::cout << "TEST ALT" << std::endl;
}
}
#endif
return false;
}
};
int main(int argc, char *argv[])
{
QApplication app(argc, argv);
MyMSGEventFilter filterObject;
app.installNativeEventFilter(&filterObject);
QMainWindow mainWindow;
mainWindow.show();
return app.exec();
}

Re: [Development] Windows plugin customisation: QWindowsKeyMapper
Hi again,
I wrote this simple test bed, but it does not seem to work. It seems that
the windows plugin does not let me process the alt key after all? I can
process the space fine, but not the alt. Am I doing something wrong or the
windows plugin does not allow the api user to intercept the native events
via the intended native event filter?

Re: [Development] Licensing of qtbase
On 7/16/22 12:00, Felix Crazzolara wrote: I wanted now to write some CMake code to ensure that Qt is always and entirely linked dynamically. For that purpose, I intended to iterate through the target properties LINK_LIBRARIES and INTERFACE_LINK_LIBRARIES of Qt5::Widgets or Qt6::Widgets and check that all dependencies resolve to shared libraries eventually. I have now two questions. First, is there some existing code in the Qt code base that does what I want already? There is code for that as part of the .pri file generation, but it's not ready to be used outside of its scope. See QtPriHelpers.cmake for details. Secondly, I noticed that an interface dependency of Qt6::Widgets is Qt6::CoreQt6::Gui and if I check whether Qt6::CoreQt6::Gui is a target with "if (TARGET Qt::CoreQt6::Gui)", it turns out that it is not. This confused me since it doesn't seem like a valid library name to me. How can I resolve Qt6::CoreQt6::Gui to an absolute file path? Qt6::CoreQt6::Gui looks wrong and should not appear as dependency. Are you sure that this is not an artifact of your code that extracts the dependencies?

[Development] CI down for a while
Hi We hit a small SNAFU with the CI and we’re fixing it. Downtime depends all on the speed of the system sadly :/ It’s been fixing for 2 hours now and closing to its end. My estimate is an hour more of downtime. -Tony ___ Development mailing list Development@qt-project.org https://lists.qt-project.org/listinfo/development
