SCROLLTEXTWINDOW
Graphics Subroutine: Scrolls the contents of a text window. This routine is only available for Windows.
Module
USE IFQWIN
CALL SCROLLTEXTWINDOW (rows)
rows |
(Input) INTEGER(2). Number of rows to scroll. |
The SCROLLTEXTWINDOW subroutine scrolls the text in a text window (previously defined by SETTEXTWINDOW). The default text window is the entire window.
The rows argument specifies the number of lines to scroll. A positive value for rows scrolls the window up (the usual direction); a negative value scrolls the window down. Specifying a number larger than the height of the current text window is equivalent to calling CLEARSCREEN ($GWINDOW). A value of 0 for rows has no effect.
Example
! Build as QuickWin or Standard Graphics app.
USE IFQWIN INTEGER(2) row, istat
CHARACTER(18) string
TYPE (rccoord) oldpos
CALL SETTEXTWINDOW (INT2(1), INT2(0), &
INT2(25), INT2(80))
CALL CLEARSCREEN ( $GCLEARSCREEN )
CALL SETTEXTPOSITION (INT2(1), INT2(1), oldpos)
DO row = 1, 6
string = 'Hello, World # '
CALL SETTEXTPOSITION( row, INT2(1), oldpos )
WRITE(string(15:16), '(I2)') row
CALL OUTTEXT( string )
END DO
istat = displaycursor($GCURSORON)
WRITE(*,'(1x,A\)') 'Hit ENTER'
READ (*,*)
! wait for ENTER
! Scroll window down 4 lines
CALL SCROLLTEXTWINDOW(INT2( -4) )
CALL SETTEXTPOSITION (INT2(10), INT2(18), oldpos)
WRITE(*,'(2X,A\)') "Hit ENTER"
READ( *,* ) ! wait for ENTER
! Scroll window up 5 lines
CALL SCROLLTEXTWINDOW( INT2(5 ))
END
