I'm working on a Text-type widget. I've written a subclass of TextSrc. It includes the Read and Scan methods and interits the remainder. Through imbedded print function calls I can see that Read() is returning text but the text never get displayed in the window (an AsciiSink). I'm lost. Would anybody be willing to help me on this one? The following is a history of Read, Scan, and GetInput() calls: (GetInput() grabs input from a file descriptor via XtAppAddInput) Scan(pos=0,typ=XawstAll,dir=XawsdRight,cnt=1,inc=1) = 0 Scan(pos=0,typ=XawstAll,dir=XawsdRight,cnt=1,inc=1) = 0 Read(pos=0) = 0 Scan(pos=0,typ=XawstEOL,dir=XawsdRight,cnt=1,inc=1) = 0 Scan(pos=0,typ=XawstEOL,dir=XawsdRight,cnt=1,inc=0) = 0 Scan(pos=0,typ=XawstAll,dir=XawsdRight,cnt=1,inc=1) = 0 Read(pos=0) = 0 Scan(pos=0,typ=XawstAll,dir=XawsdRight,cnt=1,inc=1) = 0 Read(pos=0) = 0 Scan(pos=0,typ=XawstEOL,dir=XawsdRight,cnt=1,inc=1) = 0 Scan(pos=0,typ=XawstEOL,dir=XawsdRight,cnt=1,inc=0) = 0 Scan(pos=0,typ=XawstAll,dir=XawsdRight,cnt=1,inc=1) = 0 Read(pos=0) = 0 Scan(pos=0,typ=XawstEOL,dir=XawsdRight,cnt=1,inc=1) = 0 Scan(pos=0,typ=XawstEOL,dir=XawsdRight,cnt=1,inc=0) = 0 GetInput() = 498 GetInput() = 498 GetInput() = 498 GetInput() = 498 GetInput() = 498 GetInput() = 498 GetInput() = 361 Scan(pos=0,typ=XawstAll,dir=XawsdRight,cnt=1,inc=1) = 3349 Read(pos=0) = 498 Scan(pos=0,typ=XawstAll,dir=XawsdRight,cnt=1,inc=1) = 3349 Read(pos=0) = 498 Scan(pos=0,typ=XawstAll,dir=XawsdRight,cnt=1,inc=1) = 3349 Scan(pos=0,typ=XawstAll,dir=XawsdRight,cnt=1,inc=1) = 3349 Read(pos=0) = 498 ... program `hangs' here ...
