- window when the application calls ScrollWindow.
-
- When providing scrolling for a custom wxWindow, we make the NSScroller
- send their action messages to us which we in turn package as wx window
- scrolling events. At this point, the window will not physically be
- scrolled. The application will most likely handle the event by calling
- ScrollWindow which will do the real scrolling. On the other hand,
- the application may instead not call ScrollWindow until some threshold
- is reached. This causes the window to only scroll in steps which is

- /*!
- The thumb size is intended to reflect the size of the visible portion
- of the scrolled document. As the document size increases, the thumb
- visible thumb size decreases. As document size decreases, the visible
- thumb size increases. However, the thumb size on wx is defined in
- terms of scroll units (which are effectively defined by the scroll
- range) and so increasing the number of scroll units to reflect increased
- document size will have the effect of decreasing the visible thumb
- size even though the number doesn't change.
-
- It's also important to note that subtracting the thumb size from the
- full range gives you the real range that can be used. Microsoft
- defines nPos (the current scrolling position) to be within the range
- from nMin to nMax - max(nPage - 1, 0). We know that wxMSW code always
- sets nMin = 0 and nMax = range -1. So let's algebraically reduce the
- definition of the maximum allowed position:
-
- Begin:
- = nMax - max(nPage - 1, 0)
- Substitute (range - 1) for nMax and thumbSize for nPage:
- = range - 1 - max(thumbSize - 1, 0)
- Add one inside the max conditional and subtract one outside of it:
- = range - 1 - (max(thumbSize - 1 + 1, 1) - 1)
- Reduce some constants:
- = range - 1 - (max(thumbSize, 1) - 1)
- Distribute the negative across the parenthesis:
- = range - 1 - max(thumbSize, 1) + 1
- Reduce the constants:
- = range - max(thumbSize, 1)
-
- Also keep in mind that thumbSize may never be greater than range but
- can be equal to it. Thus for the smallest possible thumbSize there
- are exactly range possible scroll positions (numbered from 0 to
- range - 1) and for the largest possible thumbSize there is exactly
- one possible scroll position (numbered 0).
