01 - Hello Java QT

相信大家已经配置好编译环境了，现在我们用intellij idea创建一个maven项目，至于项目结构，大家自己按照喜好就行。我单独会有一个Shared项目，里面是所有核心功能的实现，防止重复书写，所以我的pom.xml如下

<?xml version="1.0" encoding="UTF-8"?>
<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>one</groupId>
    <artifactId>01-HelloQT</artifactId>
    <version>1.0-SNAPSHOT</version>

    <dependencies>

        <dependency>
            <groupId>qt</groupId>
            <artifactId>Shared</artifactId>
            <version>1.0-SNAPSHOT</version>
        </dependency>
    </dependencies>
    <build>
        <plugins>
            <!-- 配置编译器插件 -->
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-compiler-plugin</artifactId>
                <version>3.11.0</version>
                <configuration>
                    <source>8</source>
                    <target>8</target>
                    <encoding>UTF-8</encoding>
                    <compilerArgs>
                        <arg>-Xplugin:Manifold</arg>
                    </compilerArgs>
                </configuration>
            </plugin>
        </plugins>
    </build>
</project>

至于maven的配置，大家用AI帮忙写吧。我贴一份自己的maven配置。

至此，我们可以开始写第一个Java QT程序了。

package one;

import io.qt.widgets.QApplication;
import io.qt.widgets.QPushButton;

public class Main {
    public static void main(String[] args) {
        QApplication.initialize(args);
        QPushButton button = new QPushButton("Quit");
        button.clicked.connect(QApplication::quit);
        button.show();
        QApplication.exec();
        QApplication.shutdown();
    }
}

 

运行后如下
