idea开发jface、swt环境搭建

背景

1. jface、swt很难找到合适的maven仓库来下载配套的版本
2. idea对eclipse套件不友好
3. eclipse的windowbuilder固然很好， 但本人更喜欢idea编程， 互相取长补短

下载套件

进入swt下载界面
以当前最新的4.29为例， 点击：

找到全部并点击超链接：

这一步可能比较慢， 稍等一会…

等待页面加载完成后， 点击选择国内镜像下载：

此时应该就开始下载了， 下载完成后解压至E:\repository\mvn\repository-4.29

配置全局jdk

此时在idea中打开Project Structure

选中Global Libraies并在右方添加所需包：

1. 不断重复第3、4步直至所有包导入完成
2. 选择Global Libraies是为了后期本地打包方便

下面是我们最终需要添加的包：

E:\repository\mvn\repository-4.29\plugins\org.eclipse.core.commands_3.11.100.v20230708-0916.jar
E:\repository\mvn\repository-4.29\plugins\org.eclipse.core.contenttype_3.9.100.v20230630-1232.jar

示例

此时环境已经搭建完成， 我们写个示例验证下：

import org.eclipse.jface.viewers.*
import org.eclipse.swt.SWT
import org.eclipse.swt.graphics.Image
import org.eclipse.swt.layout.FillLayout
import org.eclipse.swt.widgets.*
import javax.swing.CellEditor

fun main() {
    val display = Display()
    val shell = Shell(display)
    shell.layout = FillLayout()
    // 创建 TableViewer
    val viewer = TableViewer(shell, SWT.BORDER or SWT.FULL_SELECTION)
    val table: Table = viewer.table
    table.headerVisible = true
    table.linesVisible = true
    // 创建表格列
    val column = TableColumn(table, SWT.NONE)
    column.setText("姓名")
    column.setWidth(100)
    // 设置内容提供器
    viewer.setContentProvider(MyContentProvider())
    // 设置标签提供器
    viewer.setLabelProvider(MyLabelProvider())

    // 添加双击事件监听器
    viewer.addDoubleClickListener { event ->
        if (viewer.getSelection() != null) {
            viewer.editElement(viewer.getSelection(), 0)
        }
    }
    // 设置输入数据
    viewer.setInput(arrayOf("张三", "李四", "王五"))
    shell.pack()
    shell.open()

    while (!shell.isDisposed()) {
        if (!display.readAndDispatch()) {
            display.sleep()
        }
    }

    display.dispose()
}

internal class MyContentProvider : IStructuredContentProvider {
    override fun dispose() {
    }

    override fun inputChanged(viewer: Viewer?, oldInput: Any?, newInput: Any?) {
    }

    override fun getElements(inputElement: Any?): Array<Any?> {
        return if (inputElement is Array<*>) {
            inputElement as Array<Any?>
        } else arrayOfNulls(0)
    }
}

internal class MyLabelProvider : LabelProvider(), ITableLabelProvider {
    override fun getColumnText(element: Any?, columnIndex: Int): String {
        return if (element is String) {
            element
        } else ""
    }

    override fun getColumnImage(element: Any?, columnIndex: Int): Image? {
        return null
    }
}

运行结果：

打包
