RE: How to detect mouse clicks without an event handler?

It is very much better if you use OnMouseDown event instead of using
OnClick event.
Otherwise you can use the windows message facility if you are aware of
that.
 
Below is the list of various message of mouse events.
 
Try this…
 
All the best.
TABLE 3.1. MOUSE EVENT MESSAGES.

Subject: [Delphi-JEDI] How to detect mouse clicks without an event
handler?
 
Hello all,

I wonder if anyone can offer me any advice. I am trying to use an
ActiveX  
component on
my form. The component is not equipped with an OnClick event/property.
This  
means that
an event handler cannot be attached.

Trouble is, I need to detect mouse clicks on the component. I do not
have  
the component source code to adapt.

Could some transparent item be placed over it that could detect the
clicks?  
If so, what?

Thanks.
