Correct.

Also correct.

Is your MiddleContainer an actual TControl descendant class, or is it just an element ?  EWB expects that the client element is just an element, and then the outer element (the actual control) will receive all of the events for the client.

Hi Tim. Thanks for the response. MiddleContainer is just an element BUT seems to grab mouse events for the parent control (TBasicPanelControl) descendant once I override the parent GetClientElement to use MiddleContainer. Maybe I have an issue elsewhere if this is not the expected behaviour.

I've attached a schematic to show the structure of the components. The key here is that I need to dynamically add and remove TAPParticipantFormPanel instances within the MiddleContainer element of a TAPParticipantPanel instance.

I understand that the preferred method is to override GetClientElement of TAPParticipantPanel and set it to the MiddleContainer. This then allows me to simply call TAPParticipantFormPanel.Create(Self) where Self is an instance of TAPParticipantPanel.

However, this also seems to kill mouse and touch events in the TAPParticipantPanel instance.

Apologies. Long-winded I know.

No, it's not how it works.  If it did, then none of the container controls would work.

Please send me the source and I'll take a look and see where the issue is.

Hi Tim

Sorry for the delay. Been away for a few days.

I ended up rewriting this component one (long) night at which point it started working just fine with the GetClientElement override, including the mouse and touch capture. My original had evolved in complexity over a period to time so I guess that some “badness” had crept in somewhere along the line.

So, in summary, I’m good thanks!

No need.  I'm not on here as much as I need to be lately, and it's our support forums.

Cool, I'm glad that you resolved the issue.
