 Property Value

A member of the EControlActivation enumeration. The default is caAlwaysActive.

 Remarks

Specifies how ActiveX controls hosted in boxes get activated. The value of this property is used to initialize the ControlActivation property of new boxes. FlowChartX subclasses the window of any hosted control, in order to detect mouse interaction performed on it. Thus, move and resize operations can be carried out as with ordinary diagram nodes. However manipulation of the OCX' node via mouse might interfere with some user-interface feature of the control; for these reasons FlowChartX can filter the mouse messages sent to the hosted controls. A control is considered active when mouse messages are passed to it. The ControlActivation property specifies how and when to activate the control. It can have the following values:

• caAlwaysActive - the control is always active and receives all mouse messages even when its node is resized, moved or linked to other nodes;
• caWhenSelected - the control is active only when it is selected; if it is not selected the mouse messages sent to its window are filtered;
• caProgrammatic - the control is activated or deactivated programmatically via the ActivateControl and DeactivateControl methods;

Note
Only the topmost window of the hosted ActiveX control is subclassed. If the control has child windows the mouse messages sent to them are not filtered.
