RCP 中的复选框状态未更新

如何解决RCP 中的复选框状态未更新

我是 RCP 框架的初学者。在这个编辑器中，我制作了一张带有 SWT.Check Table 项目的 SWT 表。我在复选框选择方面遇到了问题。

ReloadView() 函数以一定的时间间隔触发并获取数据库更改并尝试更改数据但它没有反映在视图中。调试代码，发现没有数据问题，但没有更新现有的表/选择。

private static final Button[] checkBoxButton = new Button[size]; 
public void createPartControl(Composite parent) 
{
        toolkit = new FormToolkit(parent.getDisplay());
        compositeObj = toolkit.createComposite(parent,SWT.NONE);
        GridLayout layout = new GridLayout();
        compositeObj.setLayout(layout);
        GridData gridData = new GridData();
        gridData.verticalAlignment = GridData.FILL;
        gridData.horizontalSpan = 4;
        gridData.grabExcessHorizontalSpace = true;
        gridData.grabExcessVerticalSpace = true;
        gridData.horizontalAlignment = GridData.FILL;
        Button button = new Button(compositeObj,SWT.PUSH);
        button.setLayoutData(new GridData(SWT.BEGINNING,SWT.CENTER,false,false));
        button.setText("  Test  ");
        btsViewer = new TableViewer(compositeObj,SWT.SINGLE  | SWT.H_SCROLL | SWT.V_SCROLL |  
        SWT.FULL_SELECTION| SWT.BORDER ); 
        btsViewer.getControl().setLayoutData(gridData);
        final int[] bounds = { 30,80};
        for (int i = 0; i < titles.length; i++)
        {
            TableViewerColumn viewerColumn  = new TableViewerColumn(btsViewer,SWT.NONE);
            final TableColumn column = viewerColumn.getColumn();
            column.setText(titles[i]);
            column.setWidth(bounds[i]);
            column.setResizable(true);
            column.setMoveable(true);
            column.pack();
        }
        table = btsViewer.getTable();
        table.setHeaderVisible(true);
        table.setLinesVisible(true);
        for (int i = 0; i < titles.length; i++)
            new TableItem(table,SWT.NONE);
        ReloadView(parent);
}

public final static void ReloadView(Composite parent) {
        int Count = 0;
        dataProvider = SqlData.collectDetails();
        if (dataProvider.size() != 0) {
            for (DataProvider data : dataProvider) {
                Trigger(parent,data.sTemp,data.bstate,Count);
                Count++;
            }
        }
}
public final static void Trigger(Composite parent,String sTemp,Boolean bstate,final int Index){
    TableItem[] items = table.getItems();
    Label propertyLabel = null;

    editor[index] = new TableEditor(table);
    checkBoxButton[index] = toolkit.createButton(table,"   ",SWT.CHECK);
    checkBoxButton[index].pack();
    checkBoxButton[index].setSelection(bstate);
    editor[index].grabHorizontal = true;
    editor[index].setEditor(checkBoxButton[index],items[index],0);
        
    editor[index] = new TableEditor(table);
    propertyLabel = toolkit.createLabel(table,sTemp,SWT.CENTER);
    editor[index].grabHorizontal = true;
    editor[index].setEditor(propertyLabel,1);
}
