howto notify a RTTI controls component value has changed?
« on: November 25, 2019, 06:47:13 pm »
Hi,
  I'm trying to use to the rtti controls components for some data binding purposes to bind a custom object property to component property. The lazarus samples \lazarus\components\rtticontrols\examples\exampleproject3 shows howto connect the components property to an custom object property.
As I understand on the rtti control component side the property value is automatically pushed to the object property, in the \lazarus\components\rtticontrols\examples\exampleproject3 the TTIEdit components are connected to the properties X, Y and Size. But how can I notify from the custom object side the rtti control component that the value has changed?
