Re: OnMouseDown event on TIWChart does not work

OK, I've found a workaround. Now, I work directly with the TIWImage component. After adding the TIWImage component (called imgIWChart) and a TChart component (called chtOriginal), I use the following function to render the TChart in the TIWImage: procedure TIWForm1.RedrawGraph; var lMF : TMetafile; ...

Re: OnMouseDown event on TIWChart does not work

Hi Yeray, Thank you for your response. Mouse.CursorPos.X and Mouse.CursorPos.Y give me absolute screen coordinates.

Re: OnMouseDown event on TIWChart does not work

Hi Yeray,

The problem I have with the OnClick event is that it does not give me the position of the cursor when it is clicked.

Many thanks,

Stephen

OnMouseDown event on TIWChart does not work

My problem is that the OnMouseDown event of the TIWChart does not seem to occur when I click on the generated chart in my web browser. This is rather strange, since if I change ...
