<div dir="ltr"><div><div><div><div><div><div>Hi All,<br><br></div>Where can I find detailed documentation on IFPObserved? This page only defines the interface but not telling about the purpose of this interface:<br><br><a href="http://www.freepascal.org/docs-html/rtl/classes/ifpobserved.html">http://www.freepascal.org/docs-html/rtl/classes/ifpobserved.html</a><br>
<br></div>My questions are:<br><br></div>- what is this interface for?<br></div>- any example on when and why to use it?<br></div>- Where can I find documentation that contains explanation on the above 2 questions, so that I can get a "big picture"? For example, if there are any similar interfaces that form the foundation of FCL or LCL? <br>
<br></div>thanks!<br></div>
