NOTICE! 3.x - Breaking Changes

The following changes likely require changes in your code

• Move filline, showcursor, and hidecursor to a new module called utils.

• Fix spelling issue, utils.filline is now utils.fill_line

• Change displayops to optionmenu. Please refactor all calls from displayops() to optionmenu(): No other changes are required

• Remove legacy function showerror. Use messagebox.showerror as a replacement

• Remove legacy function askyesno_old. Use messagebox.askyesno as a replacement

• Combine displaymsg and displaymsgnodelay into one function

• Existing displaymsgnodelay calls can be changed to displaymsg(stdscr,[messages],False), so change the flag wait_for_keypress to false

• Remove redundant american function set_color. You can either use the (correct) spelling set_colour or you can not use this library.

Documentation

transitions.py

transitions contains many transitions to add animations to your program

__exec(func,args)

NOTE: THIS IS AN INTERNAL FUNCTION, IT IS NOT MEANT TO BE USED BY THE COMMON USER

This executes func(args)

horizontal_bars(stdscr,func_to_call=None,args=(),speed=1)

This is a replacement function to old's type zero. It fills the screen from the top down with horizontal white bars. It then replaces them with black bars in the same configuration.

• stdscr is a curses window object

• func_to_call is a function. If it is set to none, no function is called

• args is a tuple. The tuple will be passed to the function as arguments

• speed is an int. A higher value increases the animation speed. A lower value (0 - 1) makes it slower. If you set speed to 0, the program will crash.

random_blocks(stdscr,func_to_call=None,args=(),speed=1)

This is a replacement for old's type one transition. It fills random characters of the screen with blocks until the whole screen is covered, then it removes it in the same fashion.

• stdscr is a curses window object

• func_to_call is a function. If it is set to none, no function is called

• args is a tuple. The tuple will be passed to the function as arguments

• speed is an int. A higher value increases the animation speed. A lower value (0 - 1) makes it slower. If you set speed to 0, the program will crash.

vertical_bars(stdscr,func_to_call=None,args=(),speed=1)

This is an all new transition. It functions like horizontal bars except they are vertical and go left to right.

• stdscr is a curses window object

• func_to_call is a function. If it is set to none, no function is called

• args is a tuple. The tuple will be passed to the function as arguments

• speed is an int. A higher value increases the animation speed. A lower value (0 - 1) makes it slower. If you set speed to 0, the program will crash.

utils.py

Utils.py Contain a series of non-ui utility functions. By non-ui I mean that it does not show a screen and it is non-interactive. It is meant to enhance the creation of custom menus.

fill_line(stdscr,line,colour)

This function fills row line with the colour colour.

• stdscr is a curses window object

• line is an int. It is the row number you wish to fill in

• colour is a curses colour. Use cursesplus.set_colour() for this

hidecursor()

This function hides the console cursor

showcursor()

This function shows the console cursor

constants.py

constants.py contains a series of constants such as colours and special lines.
