Parenting Control Descending to TElement ? |

<< Since I am only adding at runtime then I imagine these two parameters are not required? >> Correct. << And, finally, if I replace my original "hack" with the steps outlined above, can I iterate the Controls array of the parent such that it'll actually return the list of children added to the Middle Container (potentially by virtue of the GetClientElement override)? >> Also correct.

<< If I override the GetClientElement per the suggestion, then I no longer receive touch / mouse events except within the MiddleContainer. The rest of the parent component is basically ignored. >> 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. Tim Young Elevate Software www.elevatesoft.com |

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. |

Mark Brooks Slikware | 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. Attachments: Component Structure.png |

Please send me the source and I'll take a look and see where the issue is. Tim Young Elevate Software www.elevatesoft.com |

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! Mark |

I'm not on here as much as I need to be lately, and it's our support forums. << 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.
