ControlContext :: loadControl - Load control
The function loads the control with the resource name passed in sCrontrol defined in design class sClassName and shows it at the position as passed in cPoint . Field properties are set by the function as follows:
- data source: inherits from current control, but can be set by context function as well
- sizing: growing in both directions when parent is a grid control, control size otherwise
- position: grid position when parent is grid control, absolute position otherwise
- margins: none
- In order to change the data source, property() can be called after loading the control.
ControlContext classes are created for field ( ADK_Field ) as well as for control ( ADK_FieldControl ) resources.
When referring a field resource, the field context will overload the context implemented for the subordinated field control (control context).
