我正在尝试编写一个方法,该方法将从表中获取当前选择,并从选择中创建一个ArrayList。SWT - 从表中选择行
方法:
public void getPlotterSelection() {
selPrinters = new ArrayList<PrinterProfile>();
int[] row = table.getSelectionIndices();
Arrays.sort(row);
if (row.length > 0) {
for(int i = row.length-1; i >= 0; i--){
PrinterProfile pp = new PrinterProfile(aa.get(i).getPrinterName(), aa.get(i).getProfileName());
selPrinters.add(pp);
}
}
}
这是我得到
错误的错误:16:16:49503 - TcLogger $ IC_LogListener.logging:? org.eclipse.core.runtime - org.eclipse.ui - 0 - 未处理的事件循环异常 org.eclipse.swt.SWTException:Widget在org.eclipse.swt.SWT.error处处理为 (SWT.java:3884 )org.eclipse.swt.SWT.error上的 (SWT.java:3799) at org.eclipse.swt.SWT.error(SWT.java:3770) at org.eclipse.swt.widgets.Widget.error (Widget.java:463) at org.eclipse.swt.widgets.Widget.checkWidget(Widget.java:336) at org.eclipse.swt.widgets.Table.getSelectionIndices(Table.java:2536) 等。 ......
问题是用这行代码
int[] row = table.getSelectionIndices();
再次..
我试图让用户选择表中的行,并把它们放在一个数组列表。
编辑添加更多的代码

}
}
这是调用该方法
Button okButton = createButton(parent, IDialogConstants.OK_ID, "OK", true);
okButton.setEnabled(true);
okButton.addSelectionListener(new SelectionAdapter() {
public void widgetSelected(SelectionEvent e) {
getPlotterSelection();
}
});
由于错误提示,似乎你的表已被处置。你把它放在什么地方?你将不得不提供更多的代码。 – Baz
