.SH "Member Enumeration Documentation"
.PP 
.SS "enum \fBQwtIntervalSymbol::Style\fP"
.PP
Symbol style. 
.PP
\fBEnumerator: \fP
.in +1c
.TP
\fB\fINoSymbol \fP\fP
No Style. The symbol cannot be drawn. 
.TP
\fB\fIBar \fP\fP
The symbol displays a line with caps at the beginning/end. The size of the caps depends on the symbol \fBwidth()\fP. 
.TP
\fB\fIBox \fP\fP
The symbol displays a plain rectangle using \fBpen()\fP and \fBbrush()\fP. The size of the rectangle depends on the translated interval and the \fBwidth()\fP, 
.TP
\fB\fIUserSymbol \fP\fP
Styles >= UserSymbol are reserved for derived classes of \fBQwtIntervalSymbol\fP that overload \fBdraw()\fP with additional application specific symbol types.
