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).
