Methods🌶️
- getViewOffsets() tuple [source]🌶️
Retrieve the vertical and horizontal offsets of the
TTkAbstractScrollViewInterface
Note
Reimplement this function to handle this event
- This method is already implemented in the following classes:
TTkAbstractScrollViewLayout
- Returns:
the (x,y) offset
- Return type:
tuple[int,int]
- viewDisplayedSize() -> (<class 'int'>, <class 'int'>)[source]🌶️

TTkAbstractScrollViewInterface
implementation.Note
Reimplement this function to handle this event
This method is already implemented in the following classes:
TTkAbstractScrollViewLayout
Unless a different iplementation is required, by default it should return
TTkWidget.size()
- Returns:
the displayed size as a tuple of 2 int elements (width,height)
- Return type:
tuple[int,int]
- viewMoveTo(x: int, y: int)[source]🌶️
