First, -where is the location of the cursor after a character is printed, and -secondly, when does the screen scroll if scrolling is enabled. -.pp -In the normal case the characters are output as expected, with the cursor -occupying the position of the next character to be output. However, when the -cursor is on the last column of the line, the cursor will remain on that -position after the last character on the line is output and will only assume -the position on the next line when the next character (the first on the next -line) is output. -.pp -Likewise, if scrolling is enabled, a scroll will be invoked only when the -first character on he first line past the bottom line of the window is -output. If scrolling is not enabled the characters will be output to the -bottom right corner of the window which is the cursor location. -.pp -This policy allows consistent behavior of the cursor at the boundary -conditions. Furthermore, it prevents a scroll from happening before it is -actually needed (the old package used to scroll when a character was -written to the right-most position on the last line). As a precedent, it -models the -.i xterm -character output conventions. -.sh 1 "Terminal State Handling" -.pp -The variable -.Vn curses_termios -contains the terminal state of the terminal. Certain historical routines -return information: -.Fn baudrate , -.Fn erasechar , -.Fn killchar , -and -.Fn ospeed . -These routines are obsolete and exist only for backward compatibility. If -you wish to use the information in the -.Vn curses_termios -structure, you should use the -\fItsetattr\fP(3) -routines. -.sh 1 "Subwindows" -.pp -Subwindows are windows which do not have an independent text structure, -.i i.e. , -they are windows whose text is a subset of the text of a larger window: the -.i parent -window. One consequence of this is that changes to either the parent or the -child window are destructive to the other, -.i i.e. , -a change to the subwindow is also a change to the parent window and a change -to the parent window in the region defined by the subwindow is implicitly a -change to the subwindow as well. -Apart from this detail, subwindows function like any other window. |
