 +   Ntics sets the number of tic marks next to the gauge.  If 0, no
     tic marks will be drawn.
 ++  Nlabels sets the number of labels next to the gauge.
 +++ Labels is an array of nul-terminated strings to be used as labels.
     If this field is NULL but nlabels is > 0, then numeric labels will be
     provided.  NOTE: the labels are not copied to any internal memory; they
     must be stored in static memory provided by the appliction.
 ++++ AutoScale allows the gauge to set its own value limits.  Default is
      False unless upper & lower limits are both 0.

 +++++ The GetValue() callback proc is called with these arguments:
 	static void
	myGetValue(gauge, client, rval)
		Widget	gauge ;
		XtPointer client ;
		XtPointer rval ;
	{
	  *(Cardinal *)rval = value ;
	}

Tip: Filter by directory path e.g. /media app.js to search for public/media/app.js.
Tip: Use camelCasing e.g. ProjME to search for ProjectModifiedEvent.java.
Tip: Filter by extension type e.g. /repo .js to search for all .js files in the /repo directory.
Tip: Separate your search with spaces e.g. /ssh pom.xml to search for src/ssh/pom.xml.
Tip: Use ↑ and ↓ arrow keys to navigate and return to view the file.
Tip: You can also navigate files with Ctrl+j (next) and Ctrl+k (previous) and view the file with Ctrl+o.
Tip: You can also navigate files with Alt+j (next) and Alt+k (previous) and view the file with Alt+o.
