Appendix A: System Routines — Windows

WinReOpen

Declaration: BOOL WinReOpen (WINDOW * w , const WIN_RECT * wRegion ,
WORD Flags , . . . )
Category(ies): Windows
Description: Reopen an existing window to a new size. Not valid for WF_SAVE_SCR
(unless using just to call WinOpen). If the window is not in the "list of
windows" then just calls WinOpen. Otherwise, it updates the Client,
Window, Clip, and Port regions. If the new window is of the same size as
the old one, then the Port region (DUP_SCR) is not cleared.
w — WINDOW struct of a previously opened window.
Inputs:
Outputs: Returns TRUE if window reopened OK, FALSE if not (bad window or not
enough memory to enlarge DUP_SCR — WinRemove called then).
Assumptions: None
Side Effects: May cause heap compression.
Availability: All versions of the TI-89 / TI-92 Plus.
TI-89 / TI-92 Plus
Differences: None

Example: This example opens a window with WF_DUP_SCR on one side of the
screen. It then reopens the same window next to that window and copies
the backup image to this new window position.
WINDOW win1;
if (WinOpen(&win1,MakeWinRect(0,20,50,70),WF_DUP_SCR|WF_TTY )) {
WinActivate(&win1);
WinClr(&win1);
WinStr(&win1,"ABCDEFGHIJKLMNOP");
/* Since the size of win1 did not change, this WinReOpen will succeed.
The backup image will not be cleared since the window size did not change. */
WinDeactivate(&win1);
WinReOpen(&win1,MakeWinRect(50,20,100,70),WF_DUP_SCR|WF_TTY);
WinActivate(&win1);
WinBackupToScr(&win1);
GKeyIn(NULL,0);
WinClose(&win1);
