我有一个有10行的表,我想要做的是:当我点击“修改”按钮时,我想将选定的表行值传递给相应的文本框。
我尝试了一些代码,这些代码并不能满足我的需求,
MainTable.addListener(SWT.Selection, new Listener() {
public void handleEvent(Event e) {
String string = "";
TableItem[] selection = MainTable.getSelection();
for (int i = 0; i < selection.length; i++)
string += selection[i] + " ";
final String Appname=string.substring(11, string.length()-2);
System.out.println(Appname);
}
});
上面的代码在Console中打印Selected行值,我想将这些值设置为Textboxes。
我该怎么做?
答案 0 :(得分:1)
以下是一些示例代码:
private static int columns = 3;
private static List<Text> texts = new ArrayList<>();
public static void main(String[] args)
{
Display display = new Display();
final Shell shell = new Shell(display);
shell.setText("StackOverflow");
shell.setLayout(new GridLayout(columns, false));
Table table = new Table(shell, SWT.FULL_SELECTION);
table.setLayoutData(new GridData(SWT.FILL, SWT.FILL, true, true, columns, 1));
table.setHeaderVisible(true);
/* Create columns */
for (int col = 0; col < columns; col++)
{
new TableColumn(table, SWT.NONE).setText("Col " + col);
}
/* Create cells */
for (int row = 0; row < 10; row++)
{
TableItem item = new TableItem(table, SWT.NONE);
for (int col = 0; col < table.getColumnCount(); col++)
{
item.setText(col, "Cell " + row + " " + col);
}
}
/* Pack columns */
for (int col = 0; col < table.getColumnCount(); col++)
{
table.getColumn(col).pack();
}
/* Create the Text fields */
for (int col = 0; col < columns; col++)
{
Text text = new Text(shell, SWT.BORDER);
texts.add(text);
}
/* Listen for selection */
table.addListener(SWT.Selection, new Listener()
{
@Override
public void handleEvent(Event e)
{
Table table = (Table) e.widget;
TableItem item = table.getItem(table.getSelectionIndex());
/* Fill the texts */
for (int col = 0; col < table.getColumnCount(); col++)
{
texts.get(col).setText(item.getText(col));
}
}
});
shell.pack();
shell.open();
while (!shell.isDisposed())
{
if (!display.readAndDispatch())
display.sleep();
}
display.dispose();
}
看起来像这样:
