Answering my own question. in iOS just create a FileDialog inside the QML file and set folder: shortcuts.pictures.It will call the iOS gallery. In Android it is a harder job once it's needed to integrate java code.

Oct 28, 2020 · Starting from Android 11, you can customize multiple signal measurement types that the framework uses to report the signal strength of 4G LTE and 5G NR radio access networks (RANs). The framework uses three functions for reporting signal strength: signal strength reporting criteria, signal strength thresholds, and signal levels. The example code below shows how you can receive signals with arguments in QML from C++. The important thing to notice in the example is that the signal's argument needs to be named identically in QML and in C++. So in this example it needs to be referred to as "text" both places, otherwise you will receive errors. main.cpp include Qt (pronounced "cute") is a widget toolkit for creating graphical user interfaces as well as cross-platform applications that run on various software and hardware platforms such as Linux, Windows, macOS, Android or embedded systems with little or no change in the underlying codebase while still being a native application with native capabilities and speed.

Signal and slot applies to everything in Qt; it comes from QObject class which is the superclass of all Qt objects, hence the central concept of Qt. On the other hand, Android uses several mechanisms for object communication.

Developing Widget Based Applications. Widgets and forms created with Qt Designer are integrated seamlessly with programmed code by using the Qt signals and slots mechanism that allows you to easily assign behavior to graphical elements. All properties set in Qt Designer can be changed dynamically within the code.

Returns the state of the line signals in a bitmap format. From this result, it is possible to allocate the state of the desired signal by applying a mask "AND", where the mask is the desired enumeration value from QSerialPort::PinoutSignals. Note: This method performs a system call, thus ensuring that the line signal states are returned

But i 07/08/2013 @Dilip_Patel I don't know the details, but it looks like this Contacts API was in Qt labs, maybe never released as a stable API, and may have been implemented only on certain platforms (probably for Nokia Symbian phones).. You probably have to use each system's native contacts list, in Android it would be done using the java API. The following list summarizes what you can do with Qt for Android: Run Widget-based and QML applications on a device or an emulator. Support for the Material Style with Qt Quick Controls. Handle Multimedia content in your Qt Quick 2 applications. Unpacking the Boot to Qt system and data archives into the /system and /data folders of the Android system Creating a device configuration file, appcontroller.conf Changing the Android boot script (init.rc) to make the device boot to Qt instead. We provide a script to perform the necessary changes. The default templates used by Qt are found in $Qt_install_dir/src/android/templates. The first step of making a custom package is to copy these files into an empty directory, for example android, under your project. Then, you need to define that path in your project's.pro file, using the variable ANDROID_PACKAGE_SOURCE_DIR: 11/06/2017

While learning Qt, I ran into this problem with a set of interconnected widgets that I wanted to update "atomically". I liked @cjhuitt's solution, but found that it goes even better with a bit of syntactic sugar based on proxy objects.
