[news.eclipse.platform.swt] Show child model window on parent modal wind

[Allan <e1vq24102@xxxxxxxxxxxxxx>]

I am trying to design a modal dialog that contains a button to open a 
child modal dialog (which will filter items in a list). Since my users 
will always click this button as soon as the parent dialog pops up, I 
would like to automatically pop this child dialog up as soon as the 
parent dialog is visible.

Tracing through _Window.open()_, I would like the child pop-up to be 
opened after the _shell.open();_ call and prior to the 
_runEventLoop(shell);_ call.

One way to go about this would be to extend Dialog, call 
_setBlockOnOpen(false);_, override _open();_, call _shell.open()_, pop 
up my filter dialog and after that closes, run the event loop.

The problem with this is _Window.runEventLoop(Shell)_ is private, so I 
would be forced to duplicate that function on my custom dialog. This 
seems like a less-than-ideal scenario.

Does anybody else have a better way to accomplish this?
