Everyone who is trying to cross-compile Qt for Orange Pi 3B can follow this tutorial: https://github.com/vverenich/CrossCompileQtForOpi

In QT Design Studio, Tab Buttons are mostly for navigation within the UI, but each tab doesn’t automatically hide other content. Usually, a StackView or Loader is needed to switch visible content depending on the active tab.

@IamSumit can you reproduce the issue and share the Support Information logs. Please refer to the following Knowledge Base Article regarding how to obtain the Support Information is https://qatools.knowledgebase.qt.io/misc/collecting-support-info/collecting-support-information-linux-mac-windows/

I am looking for a teammate for this competition, an English-speaking person preferred living in Germany.

In qnamespace.h, I add some key_code mappings : For example : enum Key { [...] KEY_CLEYVER_F1 = 0x01002122, // unused Qt keycode map for Cleyver XTremTab8 F1 Key KEY_CLEYVER_F2 = 0x01002121, // unused Qt keycode map for Cleyver XTremTab8 F2 Key [...] } And in androidjniinput, I add switches in static QKeyCombination mapAndroidKey(int key) { [...] switch (key) { case 0x00000122: // XTREMTAB f1 return Qt::KEY_CLEYVER_F1 ; [...] } I have four android keycodes : 0x121, 0x122 (for Cleyver) , 0x1a0 and 0x1a1 (for Crosscall).

Le [=] n'étant pas nécessaire ici vu qu'il n'y a rien à capturer dans la lambda. connect(obj1, &MyObject::mySignal , this, [](int arg1){ qDebug() << arg1; });

Hi, I think you can use https://forum.qt.io/category/5/qt-io-webservices category for this type of question (moved there by the way). Are these in your "unread" section ? Are they marked as you following them ?
