Problem with selection markes in Delphi IDE for Controls with SubControls

[Tom Mueller 5]

Hallo all

 

I have a control (TWinControl) that contains an other control (TPanel) and registered it in a package (see demo code in the attachment),

 

First Problem: When selecting the control in the IDE, the selection markers are only partially visible.

Second Problem: When selecting more than one control, no selection markers are visible at all.

 

Is this a known problem and are there any solutions for it?

 

Thanks

Tom

To handle this, I could register my own IOTANotifier with a IOTAWizard to get notified when the control is selected, and then draw the markers manually.

I found some notifiers for the code editor like TNTACodeEditorNotifier but could not find a proper notifier for the form designer.

If anyone has undertaken a similar task, your assistance would be greatly appreciated.
