extending DB Text component

rbuser

Hi,

I want to extend the DBText component. Therefore I inherited from
DBText. I tried to do it as explained in the checkbox sample. As soon as
I introduce an interface as published property, I always get an access
violation in rbIDE107.bpl at address 00000000.

My goal is to assign my own interfaced (translation) component to the
DBText instance at design time, so that I can access it overriding the
GetTheText-Method.

thanks,

Matt

- try making your interface property public rather than published. The RB
object inspector displays the published properties and it does not currently
support properties of type interface. (I can create a patch to fix the AV,
but the property is not going to be displayed in the RB object inspector.

- another solution is to tell the RB object inspector to ignore the
Interface property

uses
ppInspector;

initialization
TppPropertyCategoryManager.PropertyCategories.Add('Ignore',
'myInterface');

Hi,

thanks for your help. I decided to tell the RB object inspector to
ignore the interface property and now it works!

kindly regards,
