37 The \fBderwin()\fR function creates a subwindow within window \fIorig\fR, with
38 the specified number of lines and columns, and upper left corner positioned at
39 \fIbegin_x\fR, \fIbegin_y\fR relative to window \fIorig\fR. A pointer to the
40 new window structure is returned.
43 The \fBnewwin()\fR function creates a new window with the specified number of
44 lines and columns and upper left corner positioned at \fIbegin_x\fR,
45 \fIbegin_y\fR. A pointer to the new window structure is returned. A
46 full-screen window can be created by calling \fBnewwin(0,0,0,0)\fR.
49 If the number of lines specified is zero, \fBnewwin()\fR uses a default value
50 of \fBLINES\fR minus \fIbegin_y\fR; if the number of columns specified is
51 zero, \fBnewwin()\fR uses the default value of \fBCOLS\fR minus \fIbegin_x\fR.
54 The \fBsubwin()\fR function creates a subwindow within window \fIorig\fR, with
55 the specified number of lines and columns, and upper left corner positioned at
56 \fIbegin_x\fR, \fIbegin_y\fR (relative to the physical screen, \fInot\fR to
57 window \fIorig\fR). A pointer to the new window structure is returned.
60 The original window and subwindow share character storage of the overlapping
61 area (each window maintains its own pointers, cursor location, and other
62 items). This means that characters and attributes are identical in overlapping
63 areas regardless of which window characters are written to.
66 When using subwindows, it is often necessary to call \fBtouchwin\fR(3XCURSES)
67 before \fBwrefresh\fR(3XCURSES) to maintain proper screen contents.
75 Is a pointer to the parent window for the newly created subwindow.
84 Is the number of lines in the subwindow.
93 Is the number of columns in the subwindow.
102 Is the y (row) coordinate of the upper left corner of the subwindow, relative
103 to the parent window.
112 Is the x (column) coordinate of the upper left corner of the subwindow,
113 relative to the parent window.
119 On success, these functions return a pointer to the newly-created window.
120 Otherwise, they return \fBERR\fR.
