Java SWT：如何删除 SWT 表中选定的行

Question

我已经实现了一个 SWT 表，其中一列中有一个按钮小部件。单击按钮后，我将删除整行。但我不明白如何刷新/重绘/更新表格。

Table processListTable;
TableItem tableItem;
Image deleteImage = Activator.getImageDescriptor("icons/trash.gif").createImage();

private void addRowInTable() {
    tableItem = new TableItem(processListTable, SWT.FILL);
    tableItem.setText(0, "value 1");
    tableItem.setText(1, "value 2");

    TableEditor editor = new TableEditor(processListTable);

    final Button deleteButton = new Button(processListTable, SWT.PUSH | SWT.FILL);
    deleteButton.pack();

    editor.minimumWidth = deleteButtonButton.getSize().x;
    editor.horizontalAlignment = SWT.CENTER;
    editor.setEditor(deleteButtonButton, tableItem, 2);
    deleteButtonButton.setImage(deleteImage);
    deleteButtonButton.addListener(SWT.Selection, new SelectionListener(tableItem, checkButton));
}

class SelectionListener implements Listener {
    TableItem item;
    Button deleteButton;

    public SelectionListener(TableItem item, Button deleteButton) {
        this.item = item;
        this.deleteButton = deleteButton;
    }

    public void handleEvent(Event event) {

        this.deleteButton.dispose();
        this.item.dispose();
    }
}

检查 SWT 代码片段从 Table 中删除选定的项目。

只需致电table.remove(int rowIdx);而不是item.dispose();
