Qt Creator | Introduction to Application Development by Qt

  

What is Qt Creator?

It is a cross platform integrated development environment (IDE) to create C++ and QML applications for multiple desktop, embedded and mobile platforms. It comes with a code editor, and is integrated with tools for designing, coding, testing, deploying and maintaining your software throughout its product lifecycle.
For GUI in Qt, We use QML, a JavaScript variable.
For Logic : C++


Introduction

Qt Quick Controls 2 applications provide a native look and feel for several target platforms by using styles such as the macOS, 

Windows, 

or the Material style for Android. 

 

This has so far not been the case for iOS. QQC2 applications running on iOS did not look native and developers had to manually customise the controls or create their own style in order to give their UIs a more native look.

 The iOS Style is a native-looking style for iOS. It is based on pixmaps and designed to look and feel as similar as possible to the native controls in UIKit. 

To achieve this :

most of the controls use 9-patch images to draw their components 

and use QML to add animations. 

We chose a pixmap-based approach, as opposed to using native APIs like we do for the macOS and Windows style, in order to have a style that is easier to maintain, opens up for more animations, and that is not subject to visual regressions resulting from periodic updates and changes in iOS. 

This also means that over time the controls can deviate from the controls in UIKit, and will therefore need regular design updates from our side.

Generating a signed apk from Qt Creator

 As we know it's required to  be signed bundle of APK, to install in a Android Device. 1.  Generate a private key using the keytool command provided by the Java Development Kit (JDK). This key will be used to sign your .apk file. Run a command similar to the following to generate a private key: keytool -genkey -v -keystore my-release-key.keystore -alias alias_name -keyalg RSA -keysize 2048 -validity 100 00 Replace my-release-key.keystore with the desired filename for your keystore file and alias_name with a name for your key alias. 2. Packaging the .apk File : In Qt Creator, go to Build > Build APK (or Build > Prepare for Android App Bundle) to generate the release package. Qt Creator will compile your application in release mode and package it into an unsigned .apk file. 3. Signing the .apk File : Use the jarsigner tool provided by the JDK to sign your .apk file with the private key you generated earlier. Run a command similar to the following to sign the .apk ...

How make Signed Firmware from official Ardupilot using Cryptography

  Secure Boot Support This involves installing a bootloader with up to 10 public keys included and signing the ArduPilot vehicle firmware with one secret key. The bootloader will refuse to boot the firmware if the signature on the firmware doesn't match any of the public keys in the bootloader. Generating Keys To generate a public/private key pair, run the following command:     python3 -m pip install pymonocypher   Tools/scripts/signing/generate_keys.py NAME That will create two files: NAME_private_key.dat NAME_public_key.dat The generated private key should be kept in a secure location. The public key will be used to create a secure bootloader that will only accept firmwares signed with one of the public keys in the bootloader. Building secure bootloader To build a secure bootloader run this command:   Tools/scripts/build_bootloaders.py BOARDNAME --signing-key=NAME_public_key.dat That will update the bootloader in Tools/bootloaders/BOARDNAME_bl.bin to enabl...

Drone Jamming & Detecting System :

Image
Working & Concept behing drone jamming : The devices work by emitting signals at the same frequencies used by the drone equipment but with greater strength. -then breakage of signal from RC & GCS control. Components required for making a drone Jammer : 1. Audio Alarm 2. Detection & Analysis System 3. Drone Jammer Gun 4. Omnidirectional Jammer Device  5. Turnable Jammer Device  Working Procedure for Drone Detection & Jamming System : 1.) Once drone signal is received or detected on tracking system , system will try to identify whether the fly is " black fly ".      ( actually the system will compare it with black and white list , which it have.)  Case - | ( Black Fly is determined )     a.) the front - end will report data to the control system through the network. b.)  The control center that based on the terminal software to display the target orientation and flying information and activates the intrusion alarm , the wa...
