WinDupStat |
Function (ROM Call 0xE) |
Turns the duplicate status on or off.
WinDupStat turn the duplicate status of the window pointed to by w on
(Stat = TRUE) or off
(Stat = FALSE). When the duplicate status is
turned off, all writes to a window go only to the screen. When turned on, all writes
go to both the screen and the backup window. This only applies to windows created with
the WF_DUP_SCR flag set. See WinOpen for
more info. Beware that duplicate writes slow down all writes to windows with
WF_DUP_SCR flag set. WinDupStat also returns the previous
duplicate writing status.
Note: This is an official information from TI. I must admit that many things about
window management (especially about overlapping windows) is still very obscure to me.
