How can I put a “(de)select all” check box in an SWT Table header?

由 坚强是说给别人听的谎言 提交于 2019-12-01 15:34:58
问题 I have an SWT Table that I'm instantiating with the SWT.CHECK style in order to display a check box next to every row. My users have requested another check box in the header row of the table in order to allow them to select/deselect all the rows with one click. I can't see any obvious way to do it, and I've only found Swing/JTable examples through Google. Does anyone know how to do this? I'm hoping it's possible without re-implementing Table or falling back on a header context menu. 回答1:

Fatal error running an SWT application from OpenOffice

由 依然范特西╮ 提交于 2019-12-01 13:11:00
I have an OpenOffice Java addon application. I'm calling SWT from an XActionListener . Loading of SWT is done dynamically using a special class loader. The SWT window displays well, but when I hit the close button of an SWT window I get an error. I'm attaching the error file generated by this error. What is the meaning of this error? My SWT code final Display display = Display.getDefault(); final Shell shell = new Shell(); shell.setLayout(new FillLayout(SWT.VERTICAL)); shell.setSize(500, 375); shell.setText("SWT Application"); final Browser browser = new Browser(shell, SWT.NONE); browser

In swt table- sorting works for Strings how to do sorting for Integer, Double and Date values. And this only works for String ascending. Can anyone suggest a better way to do it.
