This point is debatable. My opinion is that event should be raised when 
things change without program intervention, but it seems that many 
people don't think so. For example, when I write handlers for 
checkboxes_click, events are fired when, in code, the value is changed. 
I write "ckWarn.value=true", and an event fires. This annoys me, because 
I don't need to be alerted for something I just have done...

Step 2: the tabstrip could also adjust itself automatically (expand=true)
Step 3: call the embedded form resize method. This implies that the 
tabstrip knows what it has inside, and how that form would like to 
resize. This breaks independency. Better would be to send an event to 
embedded form, and let the form decide what to do...
Step 4: (see note before). If the embedded form resizes itself, could be 
a good idea to automatically raise a resize event. I don't think so - I 
think a program should have the possibility to send events to other objects.

In this situation, I would like:

    1. The user resizes the main form, which receives a resize event to 
operate on if wanted.
    2. Children of the main form that are in some way affected 
(expand=true), receive a resize event (if they have it).
    3. The tabstrip resizes, either automatically because expand=true or 
because parent form intervention, and so its children (tabstrip 
children) receive a resize event
    4. The embedded form receives a resize event, and can ignore it or 
handle it.


It seems that one ore more things are missing in gambas... :-)
