◆ ContextCreated()
|
pure virtual |
This method can be overwritten to define the desired behavior during the OnCreateContext event.
- Parameters
-
pCanvas [in/out] Pointer to the current Canvas object
- Returns
- standard result
◆ ContextDestroyed()
|
pure virtual |
This method can be overwritten to define the desired behavior during the OnDestroyContext event.
- Returns
- standard result
◆ OnCreateContext()
|
pure virtual |
This oneshot method is called once when the transition from runlevel 4 to runlevel 5 occurs The use of this function is purely to call the ContextCreated Callbacks within the user implementation.
It is not intended to be overridden by Drawer implementations.
- Parameters
-
pCanvas [in/out] Pointer to the current Canvas object
- Returns
- standard result
◆ OnDestroyContext()
|
pure virtual |
This oneshot method is called once when the transition from runlevel 5 to runlevel 4 occurs The use of this function is purely to call the ContextCreated Callbacks within the user implementation.
It is not intended to be overridden by Drawer implementations.
- Returns
- standard result
