我有下表:
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();
}
答案 0 :(得分:4)
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);
}
}
