Window and bottom-positioned Toolbar

Is there a way to create Window with bottom positioned buttons?

We create Tree in Window and we need to place “Select” and “Cancel” (and probably some others) buttons to the very bottom as a normal form (Submit/Cancel) does and those buttons should not be scrollabe.

Thanks!

No, window does not support such functionality.
You can add status bar for bittons like this:
var sb = wnidow(id).attachStatusBar();
sb.setText("<input type=‘button’…>");
