emitting a signal for refeshing entries

[Peter Van Osta <pvosta unionbio-eu com>]

Hi,

I have a window in which there are several other elements, such as 
spinbuttons, combo boxes, etc. . There is one combo box which allows to 
choose a specific application which includes different settings for the 
spinbuttons, other combo boxes, etc.

I want to send one signal (if possible), such as an expose_event which I 
already use to show the current updated values if something has changed 
between windows after re-exposure. Is it possible to emit an "expose" 
signal to the main window, so it is propagated to its "chilren" ? Or do 
I have to emit signals to each one of the widgets in the main window ?

Best regards,
