LAutomation::AddContainer

#include "ltwrappr.h"

L_INT LAutomation::AddContainer(pLContainer , pModeData)

Adds a new container to the automation list of containers.

Parameters

LContainer * pLContainer

Pointer to a container object.

L_VOID * pModeData

Pointer to a structure that contains information about the mode used to create the specified automation handle. If the automation handle was created using AUTOMATION_MODE_VECTOR, pModeData should point to a VECTORHANDLE structure. If the automation handle was created using AUTOMATION_MODE_PAINT, pModeData should point to a CONTAINERPAINTDATA structure.

Returns

Value Meaning
SUCCESS The function was successful.
< 1 An error occurred. Refer to Return Codes.

Comments

For an SDI application, usually a single container for the current SDI window will be added. For an MDI application, usually a new container will be added every time a new MDI child window is created.

The newly added container will become the active automation container.

Adding a new container will provide all automation functionality to the window that owns the newly added container.

To remove a container from the automation list of containers, call LAutomation::RemoveContainer.
