使用单列格式化SWT表

我有下表:

enter image description here

我想要做的是将列扩展到窗口的大小,而不显示没有列的额外行(项目列右侧的单元格)。我对SWT的大部分内容都有点熟悉,但这些表仍然令我感到困惑。

我希望能够通过点击该行的任意位置来选择项目。

以下是我用于制作上述屏幕截图的简单UI代码:

public static void main(String[] args) { 
    Display display = new Display();
    Shell shell = new Shell(display);
    shell.setLayout(new GridLayout());

    Table table = new Table (shell, SWT.MULTI | SWT.BORDER | SWT.FULL_SELECTION);
    table.setLinesVisible (true);
    table.setHeaderVisible (false);
    GridData data = new GridData(SWT.FILL, SWT.FILL, true, true);
    data.heightHint = 200;
    table.setLayoutData(data);

    TableColumn column = new TableColumn (table, SWT.NONE);
    column.setResizable(true);
    int count = 15;
    for (int i=0; i<count; i++) {
        TableItem item = new TableItem (table, SWT.NONE);
        item.setText (0, "item " + i);
    }
    column.pack();

    shell.pack();
    shell.open();

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

让您的Table成为其父级的唯一子级,并创建一个包含以下内容的列:

import org.eclipse.jface.viewers.ColumnWeightData;
import org.eclipse.swt.widgets.Table;
import org.eclipse.swt.widgets.TableColumn;
import org.eclipse.jface.layout.TableColumnLayout;

public class ColumnHelper {
    public static void createColumn(Table table) {
        TableColumnLayout layout = new TableColumnLayout();
        table.getParent().setLayout(layout);
        TableColumn column = new TableColumn (table, SWT.NONE);
        layout.setColumnData(column, new ColumnWeightData(10));
    }
}

如果您遇到strange, growing resize behaviour表,请将TableColumnLayout替换为:

/** Forces table never to take more space than parent has*/
public class TableColumnLayout extends org.eclipse.jface.layout.TableColumnLayout {

    @Override
    protected Point computeSize(Composite composite, int wHint, int hHint, boolean flushCache) {
        return new Point(wHint, hHint);
    }
}
