how to create an "event transparent" widget?

Message 1 in thread

Is it possible to create an "event dead" widget in Qt, i.e. a widget you can 
paint on but that does not react on (especially) user action like keyboard or 
mouse events?

My main problem is the DnD functionality.
While e.g. setting a mask on the widget masks all mouse events in the masked 
area as well (as expected) and thus also allows to set the keyboard focus 
properly, the DnD events aren't masked and while i was able to send down 
mouse events of the non masked area to the below widgets (region comaration + 
QCoreApplication::sendEvent()) the DnD events are allways pushed back upwards 
to the widget that should have been "event dead" resulting in a recursion.

I can of course catch the recursion, but that won't help me as still the lower 
widgets won't handle the DnD events....

I know that recent X versions support eventshaping (like XShape) but have no 
idea about Windows and Mac (or what will happen if i apply this to the Qt 
widgets)

Thanks,
Thomas

Hello,

  I am trying to create a set of custom functions to be used during the
qmake process. I have read the documentation in the help that shipped
with QT v4.2.3 that go along with creating custom functions to be used
by QMake.

  I have a common file (name: common.pro) that contains what I intended
to be the definition of the custom function. The function would take two
parameters, both of type string, and then it would iterate through the
list of times executing actions on files that passed a filter.

  My question resides on how to define a function in a .pro file, I have
included the foot print of the function as it stands now. QMake is
trying to execute this function verses define it. Can anyone help
explain how I can define the function?

[ Custom Function ]
defineCreateSDK(headersAndInline, destinationLocation) {
    #
    # ... code here.
    #
}

I would start here:

I added some stuff regarding functions.

...as s.e. hooked onto this thread, what could be misinterpreted as it was 
solved - it is NOT.

Sorry for the recall,
