[Kde-bindings] Ruby, sendEvent and KDE

[Stefan Champailler]

Hi Richard,

Thank you for answering ! As you can see from my previous messages 
I've made some progress and I'm now heading to complete my goal.

As a side note, if I want to simulate a click, it is for example, to 
simulate a click on some JavaScript controlled elements or to make 
sure I have the mouse cursor positioned on the link so I can take a 
picture (very helpful in tutorials)... So there _are_ good reasons 
to simulate real mouse movements even though the KHTML part does 
provide openURL(xxx) functions !

Also, for those who followed my other thread, I'm now thinking of 
decoupling my code in two ruby scripts connected by DCOP. This way I 
achieve "multithreading" or parallel processing, even though I use 
Qt components and KDE event loops... Ain't clean but will probably 
work..

Cheers !
