SUMMARY
The TEXT sample demonstrates how to display and print text using a CScrollView derived class. It is possible to implement text output in a CScrollView class by overriding OnDraw and drawing the entire document using TextOut. However, further steps are required to draw the text efficiently and to include support for multipage documents. Here are the features implemented in this sample and the locations: <pre class="fixed_text">Feature                                       Locations(s) ---

Calculation of various metrics necessary      METRICS.CPP: for text output:                              CViewMetrics::Compute

Optimized screen and printer output for       TEXTVIEW.CPP: multipage documents:                          OnDraw (two overrides) OnPrint ComputeVisibleLines ComputePrintableLines

Calculation of page count:                    METRICS.CPP: CPageMetrics::Compute

Visual indication of pagination:              METRICS.CPP (Calculation) CPageMetrics::IsPageBreak

TEXTVIEW.CPP (Display) OnDraw DrawPageBreak

User-defined margins:                         METRICS.CPP (Calculation) CMargins::Compute
