Qml gui and nogui mode[solved]

Vardan95

hi guys,my program has two modes GUI(on qml) and non GUI(command line).What code I must write for changing mode by passing argument in cmd for example if I pass nameofapp.exe -no-gui must be work no-gui version for simple qt/c++ application we have this code

@QCoreApplication* createApplication(int &argc, char *argv[])
{
for (int i = 1; i < argc; ++i)
if (!qstrcmp(argv[i], "-no-gui"))
return new QCoreApplication(argc, argv);
return new QApplication(argc, argv);
}

int main(int argc, char* argv[])
{
QScopedPointer<QCoreApplication> app(createApplication(argc, argv));

if (qobject_cast<QApplication *>(app.data())) {
   // start GUI version...
} else {
   // start non-GUI version...
}

return app->exec(&#41;;

}@

It's from documentation,I want such of this for qml

Hi and welcome to devnet,

The most simple way is to create a default qml application and copy it's main content (except the QApplication creation) in place of // start GUI version

You mean kind of this?
@QScopedPointer<QCoreApplication> app(createApplication(argc, argv));
if (qobject_cast<QApplication *>(app.data())) {
qmlRegisterType<CoreAdapter>("conv.core", 1, 0, "CoreAdapter");
QQmlApplicationEngine engine;
engine.load(QUrl(QStringLiteral("qrc:///main.qml")));
} else {
// start non-GUI version...
}
return app->exec();@

Did you mean in gui mode ?

Vardan95

Unfortunately, I wrote wrong,sorry for it. but this code does not work

SGaist

You'll have to be more specific. "Does not work" doesn't really say what is currently happening. What should you be getting ? What are you getting ? What parameters are you passing to your application ?

ok,in cmd I wrote app-name.exe -no-gui,program started,but not showed,it's just ran in process(Task Manager).The same with -gui parameter

SGaist

-no-gui implies that there will be no gui so there's nothing to be shown.

As for a "gui" run, your QQmlApplicationEngine goes out of scope before you reach app->exec() so nothing will be shown either.

but for nu-gui I have function,and I want to execute that function(it's a simple c++ console app, wich workes for non qml version)

and for "gui" I understand that,and I apologise for bad code :),but the result is same in this case too
@QScopedPointer<QCoreApplication> app(createApplication(argc, argv));
if (qobject_cast<QApplication *>(app.data())) {
qmlRegisterType<CoreAdapter>("conv.core", 1, 0, "CoreAdapter");
QQmlApplicationEngine engine;
engine.load(QUrl(QStringLiteral("qrc:///main.qml")));
return app->exec();
} else {
// start non-GUI version...
return app->exec();

If you replace your main content with

@
QApplication app(argc, argv);
qmlRegisterType<CoreAdapter>("conv.core", 1, 0, "CoreAdapter");
QQmlApplicationEngine engine;
engine.load(QUrl(QStringLiteral("qrc:///main.qml")));
return app.exec();
@

is it working ? If not, then first ensure you have it working before adding your gui/non-gui code

It workes only from Qt Creator,but from debug/release folders it's doesn't run
I put some .dll files into that folder,but it didn't help.I get this error

and dll files !http://s3.postimg.org/werdy9apv/dll_s.jpg(dll)!

If you want to run it in the explorer then you need to follow the same step as if you were deploying it on another computer.

Follow this fine "wiki entry":http://qt-project.org/wiki/Deploy_an_Application_on_Windows
