Implementations

impl Window

pub fn addch<T: ToChtype>(&self, ch: T) -> i32

Adds the chtype ch to the window at the current cursor position, and advances the cursor.

Note that chtypes can convey both text (a single character) and attributes, including a color pair.

pub fn addstr<T: AsRef<str>>(&self, string: T) -> i32

Write all the characters of the string to the given window.

The functionality is similar to calling window.addch() once for each character in the string.

pub fn addnstr<T: AsRef<str>>(&self, string: T, length: usize) -> i32

Write at most length characters; if length is negative, then the entire string will be added.

pub fn attrget(&self) -> (chtype, i16)

Retrieve attributes for the given window.

use crosscurses::{A_BOLD, initscr, endwin};
let window = initscr();
window.attron(A_BOLD);
let (active_attributes, color_pair) = window.attrget();
assert_eq!(A_BOLD, active_attributes);
endwin();

pub fn attroff<T: Into<chtype>>(&self, attributes: T) -> i32

Turns off the named attributes without affecting any other attributes.

pub fn attron<T: Into<chtype>>(&self, attributes: T) -> i32

Turns on the named attributes without affecting any other attributes.

pub fn attrset<T: Into<chtype>>(&self, attributes: T) -> i32

Sets the current attributes of the given window to attributes.

pub fn bkgd<T: Into<chtype>>(&self, ch: T) -> i32

Not only change the background, but apply it immediately to every cell in the window.

pub fn bkgdset<T: Into<chtype>>(&self, ch: T)

Manipulate the background of a window. The background is a chtype consisting of any combination of attributes and a character; it is combined with each chtype added or inserted to the window by addch() or insch(). Only the attribute part is used to set the background of non-blank characters, while both character and attributes are used for blank positions.

pub fn border<T: ToChtype>( &self, left_side: T, right_side: T, top_side: T, bottom_side: T, top_left_corner: T, top_right_corner: T, bottom_left_corner: T, bottom_right_corner: T, ) -> i32

Draw a border around the edges of the window.

pub fn chgat(&self, n: i32, attributes: chtype, color_pair: i16) -> i32

Changes the attributes of a given number of characters starting at the current cursor location. It does not update the cursor and does not perform wrapping. A character count of -1 or greater than the remaining window width means to change attributes all the way to the end of the current line.

pub fn clear(&self) -> i32

Similar to erase(), but also calls clearok() to ensure that the the window is cleared on the next refresh().

pub fn clearok(&self, bf: bool) -> i32

With clearok(), if bf is TRUE, the next call to refresh() with this window will clear the screen completely and redraw the entire screen.

pub fn clrtobot(&self) -> i32

Clear the window from the current cursor position to the end of the window.

pub fn clrtoeol(&self) -> i32

Clear the window from the current cursor position to the end of the current line.

pub fn color_set(&self, color_pair: i16) -> i32

Sets the current color of the given window to the foreground/background combination described by the color pair parameter.

pub fn copywin( &self, destination_window: &Window, src_tr: i32, src_tc: i32, dst_tr: i32, dst_tc: i32, dst_br: i32, dst_bc: i32, overlay: bool, ) -> i32

Copy all text from this window to the destination window. The arguments src_tc and src_tr specify the top left corner of the region to be copied. dst_tc, dst_tr, dst_br, and dst_bc specify the region within the destination window to copy to. The argument “overlay”, if TRUE, indicates that the copy is done non-destructively (as in overlay()); blanks in the source window are not copied to the destination window. When overlay is FALSE, blanks are copied.

pub fn delch(&self) -> i32

Delete the character under the cursor. All characters to the right of the cursor on the same line are moved to the left one position and hte last character on the line is filled with a blank. The cursor position does not change.

pub fn deleteln(&self) -> i32

Delete the line under the cursor. All lines below are moved up one line, and the bottom line is cleared. The cursor position does not change.

pub fn delwin(self) -> i32

Deletes the window, freeing all associated memory. In the case of overlapping windows, subwindows should be deleted before the main window.

pub fn derwin( &self, nlines: i32, ncols: i32, begy: i32, begx: i32, ) -> Result<Window, i32>

The same as subwin(), except that begy and begx are relative to the origin of the window rather than the screen.

There is no difference between subwindows and derived windows.

pub fn draw_box<T: ToChtype>(&self, verch: T, horch: T) -> i32

Draw a border around the edge of the window. If any argument is zero, an appropriate default is used.

pub fn dupwin(&self) -> Window

Creates an exact duplicate of the window.

pub fn enclose(&self, y: i32, x: i32) -> bool

Reports whether the given screen-relative y, x coordinates fall within the window.

pub fn erase(&self) -> i32

Copies blanks (i.e. the background chtype) to every cell of the window.

pub fn get_beg_y(&self) -> i32

Get the upper-left y coordinate of this window

pub fn get_beg_x(&self) -> i32

pub fn get_beg_yx(&self) -> (i32, i32)

Get the upper-left y and x coordinates of this window

pub fn getbkgd(&self) -> chtype

Returns the given window’s current background character and attributes.

pub fn getch(&self) -> Option<Input>

Read a character from the terminal associated with the window.

In nodelay mode, if there is no input waiting, None is returned. In delay mode, the program will hang until the system passes text through to the program. Depending on the setting of cbreak(), this will be after one character or after the first newline. Unless noecho() has been set, the character will also be echoed into the designated window.

If keypad() is TRUE, and a function key is pressed, the token for that function key will be returned instead of the raw characters. If nodelay(win, TRUE) has been called on the window and no input is waiting, None is returned.

pub fn get_cur_x(&self) -> i32

Return the current x coordinate of the cursor

pub fn get_cur_y(&self) -> i32

Return the current y coordinate of the cursor

pub fn get_cur_yx(&self) -> (i32, i32)

Return the current y and x coordinates of the cursor

pub fn get_max_x(&self) -> i32

Return the maximum x value of this Window, in other words the number of columns.

pub fn get_max_y(&self) -> i32

Return the maximum y value of this Window, in other words the number of rows.

pub fn get_max_yx(&self) -> (i32, i32)

Return the maximum y and x value of this Window

pub fn hline<T: ToChtype>(&self, ch: T, n: i32) -> i32

Draw a horizontal line using ch from the current cursor position. The line is at most n characters long, or as many as fit into the window.

pub fn insdelln(&self, n: i32) -> i32

For positive n, insert n lines into the specified window above the current line. The n bottom lines are lost. For negative n, delete n lines (starting with the one under the cursor), and move the remaining lines up. The bottom n lines are cleared. The current cursor position remains the same.

pub fn insertln(&self) -> i32

A blank line is inserted above the current line and the bottom line is lost.

pub fn is_linetouched(&self, line: i32) -> bool

Returns true if the specified line in the specified window has been changed since the last call to refresh().

pub fn is_touched(&self) -> bool

Returns true if the specified window has been changed since the last call to refresh().

pub fn keypad(&self, use_keypad: bool) -> i32

Controls whether getch() returns function/special keys as single key codes (e.g., the left arrow key as KEY_LEFT).

Per X/Open, the default for keypad mode is OFF. You’ll probably want it on. With keypad mode off, if a special key is pressed, getch() does nothing or returns ERR.

pub fn insch<T: ToChtype>(&self, ch: T) -> i32

Insert the character ch before the character under the cursor.

All characters to the right of the cursor are moved one space to the right, with the possibility of the rightmost character on the line being lost. The insertion operation does not change the cursor position.

pub fn mouse_trafo(&self, y: i32, x: i32, to_screen: bool) -> (i32, i32)

Converts between screen-relative and window-relative coordinates.

A to_screen parameter of true means to convert from window to screen; otherwise the reverse.

pub fn mv(&self, y: i32, x: i32) -> i32

The cursor associated with the window is moved to the given location.

This does not move the physical cursor of the terminal until refresh() is called. The position specified is relative to the upper left corner of the window, which is (0,0).

pub fn mvaddch<T: ToChtype>(&self, y: i32, x: i32, ch: T) -> i32

moves the cursor to the specified position and adds ch to the specified window

pub fn mvaddstr<T: AsRef<str>>(&self, y: i32, x: i32, string: T) -> i32

Write all the characters of the string str to the given window. The functionality is similar to calling waddch() once for each character in the string.

pub fn mvaddnstr<T: AsRef<str>>(&self, y: i32, x: i32, string: T, n: i32) -> i32

Write the first’n’ characters of the string str to the given window.

pub fn mvchgat( &self, y: i32, x: i32, n: i32, attributes: chtype, color_pair: i16, ) -> i32

Moves the cursor and changes the attributes of a given number of characters starting at the cursor location. It does not update the cursor and does not perform wrapping. A character count of -1 or greater than the remaining window width means to change attributes all the way to the end of the current line.

pub fn mvderwin(&self, pary: i32, parx: i32) -> i32

Moves a derived window (or subwindow) inside its parent window.

The screen-relative parameters of the window are not changed. This routine is used to display different parts of the parent window at the same physical position on the screen.

pub fn mvinch(&self, y: i32, x: i32) -> chtype

Retrieves the character and attribute from the specified window position, in the form of a chtype.

pub fn mvinsch<T: ToChtype>(&self, y: i32, x: i32, ch: T) -> i32

Move the cursor and then insert the character ch before the character under the cursor.

First performs a cursor movement using wmove, and returns an error if the position is outside the window. All characters to the right of the cursor are moved one space to the right, with the possibility of the rightmost character on the line being lost. The insertion operation does not change the cursor position.

pub fn mvprintw<T: AsRef<str>>(&self, y: i32, x: i32, string: T) -> i32

Add a string to the window at the specified cursor position.

pub fn mvwin(&self, y: i32, x: i32) -> i32

Moves the window so that the upper left-hand corner is at position (y,x).

If the move would cause the window to be off the screen, it is an error and the window is not moved. Moving subwindows is allowed.

pub fn nodelay(&self, enabled: bool) -> i32

Controls whether wgetch() is a non-blocking call. If the option is enabled, and no input is ready, wgetch() will return ERR. If disabled, wgetch() will hang until input is ready.

pub fn noutrefresh(&self) -> i32

Copies the window to the virtual screen.

pub fn overlay(&self, destination_window: &Window) -> i32

Overlays this window on top of destination_window. This window and destination_window are not required to be the same size; only text where the two windows overlap is copied. overlay() is non-destructive.

pub fn overwrite(&self, destination_window: &Window) -> i32

Overlays this window on top of destination_window. This window and destination_window are not required to be the same size; only text where the two windows overlap is copied. overwrite() is destructive.

pub fn printw<T: AsRef<str>>(&self, string: T) -> i32

Add a string to the window at the current cursor position.

pub fn refresh(&self) -> i32

Copies the named window to the physical terminal screen, taking into account what is already there in order to optimize cursor movement.

This function must be called to get any output on the terminal, as other routines only manipulate data structures. Unless leaveok() has been enabled, the physical cursor of the terminal is left at the location of the window’s cursor.

pub fn scrollok(&self, bf: bool) -> i32

If enabled and a scrolling region is set with setscrreg(), any attempt to move off the bottom margin will cause all lines in the scrolling region to scroll up one line.

pub fn setscrreg(&self, top: i32, bot: i32) -> i32

Sets a scrolling region in a window.

“top” and “bot” are the line numbers for the top and bottom margins.

pub fn subwin( &self, nlines: i32, ncols: i32, begy: i32, begx: i32, ) -> Result<Window, i32>

Creates a new subwindow within a window.

The dimensions of the subwindow are nlines lines and ncols columns. The subwindow is at position (begy, begx) on the screen. This position is relative to the screen, and not to the window orig. Changes made to either window will affect both. When using this routine, you will often need to call touchwin() before calling refresh().

pub fn timeout(&self, milliseconds: i32)

Set blocking or non-blocking reads for the specified window.

The delay is measured in milliseconds. If it’s negative, a blocking read is used; if zero, then non-blocking reads are done – if no input is waiting, ERR is returned immediately. If the delay is positive, the read blocks for the delay period; if the period expires, ERR is returned.

pub fn touch(&self) -> i32

Throws away all information about which parts of the window have been touched, pretending that the entire window has been drawn on.

This is sometimes necessary when using overlapping windows, since a change to one window will affect the other window, but the records of which lines have been changed in the other window will not reflect the change.

pub fn touchline(&self, start: i32, count: i32) -> i32

Throws away all information about which parts of the window have been touched, pretending that the entire window has been drawn on.

This is sometimes necessary when using overlapping windows, since a change to one window will affect the other window, but the records of which lines have been changed in the other window will not reflect the change.

pub fn touchln(&self, y: i32, n: i32, changed: bool) -> i32

Makes n lines in the window, starting at line y, look as if they have or have not been changed since the last call to refresh().

pub fn ungetch(&self, input: &Input) -> i32

Places ch back onto the input queue to be returned by the next call to getch().

pub fn untouch(&self) -> i32

Marks all lines in the window as unchanged since the last call to refresh().

pub fn vline<T: ToChtype>(&self, ch: T, n: i32) -> i32

Draw a vertical line using ch from the current cursor position. The line is at most n characters long, or as many as fit into the window.
