The information in this article applies to:

SUMMARY

FoxPro supports a limited number of line styles as demonstrated by the program in this article.

MORE INFORMATION

FoxPro supports five main line styles. Styles 1 through 4 are the combi- nations of short dashes, long dashes, and dots. 

Style   Line Definition

  1     dot-dot-dot-dot-dot
  2     long dash-long dash-long dash-long dash
  3     short dash-dot-short dash-dot-short dash
  4     short dash-dot-dot-short dash-dot-dot-short dash
  5     solid line
If you examine the line definition code inside an SPR, you may see that FoxPro will use a line style of 8, which is an undocumented line style. Line styles 5 on up are all solid lines, as the code sample will show.

The other parameter of significance is identified below as PenWidth. This value has no bearing on the width of line styles 1 through 4. However, it does affect the width of the primary line style 5 (the solid line). Any value higher than 6 will be treated as a value of 1.
