616.0. "Modify the buffer size of a decterm" by LIL01::GOURDIN () Tue Apr 18 1989 10:24

Hi,
    
When I am in a DECWINDOWS SESSION I need to create a DECWINDOWS DECTERM
with a buffer of about 2000 lines or more.
    The reason is we want to visualize a file in one unique window to
give to the user the SCROLL BAR facility for the entire file in one time.
    
I haven't found it in CHILD parameters for "CREATION OF A TERMINAL
    EMULATOR" and there is no parameter about buffer size of scrolled
    lines in [SYSMGR]DECW$terminal_default.dat.
    
When you customize the session manager you can modify the value of
    "SCROLLED LINES SAVED" beetween 10 and 200, what is the parameter
    which is modified?.
    
   Best reguards.

616.1	Can't be done, at least in the SDC version	HANNAH::MESSENGER	Bob Messenger	`Wed Apr 19 1989 00:27`	8
	Re: .0 By "buffer size" do you mean the number of lines recorded off the top? There is no way to change this in DECterm V1; the maximum is always 100 lines.the session manager parameter has nothing to do with DECterm. -- Bob
616.2	Is there another WAY??	LIL01::GOURDIN		`Wed Apr 19 1989 15:01`	18
	Indeed I mean the number of lines recorded off the top. Is there no way to change this in DECWINDOWS with another parameter in another window (i.e. in a FILEVIEW TASK OUTPUT)??. If there is no way in DECWINDOWS, is it possible to scroll any file (i.e. one of 100 lines and another of 1000 lines) with a SCROLL WINDOW widget ??. Is it a dynamic resize of the number of lines recorded off the top beetween a 100 lines file and a 2000 lines file??. It's for a french customer who wants to visualize a file which is the result of a "SYSTEM EXPERT". The end of the project is fixed to the May, 3rd. Thanks for your help. -- Christian.

	Sounds like you want to put together an application that reads the file in question and displays it in an SText widget. You could then use the scroll bars in the SText widget to move around the file. Of course, it would be even flashier to do more with the data but you have a small time window to do this. Dick

	Use the notepad utility provided with DECwindows. It does exactly what you are asking for.
