- Sub: reShowReverted & Naming
-
- The thing that ShowReverted does is to check the view's size. In the case you
- mention, the size of the view is shrinking so ForceRedraw forces the new view
- size to redraw itself. This leaves part of the old view on the screen. I
- agree with you that the TTEView methods that change the text should take care
- of this.
-
- ShowReverted is called after revert command to tell the view to show itself.
- It's a separate method in case the view needs to do something special when a
- Revert happens.
-
- Hysteresis in the context of a mouse command specifies how far the mouse has to
- move from the initial click before MacApp will assume the mouse is moving.
- This is to allow for the case where the user clicks the mouse, but moves
- slightly in the process.
-
- The dictionary describes hysteresis as the failure of a property to return to
- its original state when the cause of its change is removed. So it looks like I
- used the term for the opposite case (where the property doesn't immediately
- change even though you try to cahnge it).
-
- You are 100% right that naming is important in something like MacApp.
