QT6 build

[helge17]

Since QT seems to be more modern and better maintained than SWT and JFX, it might make sense to get TuxGuitar running again with QT.

First steps have already been made here:
#20
OmixVisualization/qtjambi#157

I was able to build the Hello World example of QtJambi on Debian unstable (Sid) currently shipping QT 6.6.2 with the following:

pom.xml:

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://maven.apache.org/POM/4.0.0
		http://maven.apache.org/xsd/maven-4.0.0.xsd">
	<modelVersion>4.0.0</modelVersion>
	<groupId>hello.world</groupId>
	<artifactId>hello-world</artifactId>
	<version>0.1</version>
	<name>${project.artifactId}</name>

	<properties>
		<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
		<!-- Installed QT version -->
		<qt-version>6.6.2</qt-version>
	</properties>


	<dependencies>
		<dependency>
			<groupId>io.qtjambi</groupId>
			<artifactId>qtjambi</artifactId>
			<version>${qt-version}</version>
		</dependency>
		<dependency>
			<groupId>io.qtjambi</groupId>
			<artifactId>qtjambi-native-linux-x64</artifactId>
			<version>${qt-version}</version>
		</dependency>
	</dependencies>

	<build>
		<plugins>
			<plugin>
				<artifactId>maven-compiler-plugin</artifactId>
				<version>3.8.0</version>
				<configuration>
					<source>9</source>
					<target>9</target>
				</configuration>
			</plugin>
		</plugins>
	</build>

</project>

src/main/java/hello/world/HelloWorld.java:

import io.qt.widgets.*;
public class HelloWorld {
    public static void main(String[] args) {
        QApplication.initialize(args);
        QMessageBox.information(null, "QtJambi", "Hello World!");
        QApplication.shutdown();
    }
}

Install Maven, Java and QT6 libs:
$ sudo apt install default-jre maven libqt6core6 libqt6gui6 libqt6widgets6
Build:
$ mvn package
Run:
$ java -cp ~/.m2/repository/io/qtjambi/qtjambi/6.6.2/qtjambi-6.6.2.jar:target/hello-world-0.1.jar HelloWorld

That's very good news, thanks
I'll probably re-open #20 when I find some time for this (currently low priority).

I just added my QT6 code to the tuxguitar-next branch:
https://github.com/helge17/tuxguitar/tree/tuxguitar-next/desktop/TuxGuitar-ui-toolkit-qt
https://github.com/helge17/tuxguitar/tree/tuxguitar-next/desktop/build-scripts/tuxguitar-linux-qt
When building, I face similar problems to those you have described here: #20 (comment):
