Hi all,

I want to send Lon./Lat. values to GoogleEarth and force it to search the
location I want for me. Now, I have got the handle of  GoogleEarth window
and its component handle, however I found the combobox component of
GoogleEarth is  QComboBox which inherit from QWidget (QT). Is there a way to
send message to control QComboBox as to control ComboBox in windows?
Moreover, CB_XXXX messages seems not work, but , 'SetWindowPos' can
show/hide the QComboBox I found. I have no experience on QT, can anyone tell
me what the mechanism QT is? And how can I control it? Does QT also support
messages concepts ?

thanks for any help,

Avex
