Dear Maintainer, Quoting the manual: The wmouse_trafo function transforms a given pair of coordinates from stdscr-relative coordinates to coordinates relative to the given window or vice versa. • If the parameter to_screen is TRUE, the pointers pY, pX must reference the coordinates of a location inside the window win. They are converted to window-relative coordinates and returned through the pointers. If the conversion was successful, the function returns TRUE. • If to_screen is FALSE, the pointers pY, pX must reference window-relative coordinates. They are converted to stdscr-relative coordinates if the window win en‐ closes this point. In this case the function returns TRUE. So, if to_screen is true, then the coordinates are converted from screen to window coordinates? And if to_screen is false, then window corrdinates are converted to screen coordinates? Given -stdscr------------ | | | | | | | -win------ | | |x | | | | | | | | | | | |________| | |_________________| I should expect wmouse_trafo(win, &1, &1, true) to yield 6, 6, and wmouse_trafo(win, &6, &6, false) to yield 1, 1? (And both wmouse_trafo(win, &1, &1, false) and wmouse_trafo(win, &6, &6, true) to return false?) Or, to put it bluntly, is the to_screen parameter actually to_window, and not to_screen? What is the purpose of mouse_trafo() if a stdscr/stdscr mapping is a no-op? Is the first sentence conflating the stdscr window with the physical, uh, window^Wscreen^Wdisplay?
