class TUI::Painter

• TUI::Painter
• Reference
• Object

Overview

Created by the application, passed down the widget tree by using #push to alter relative coordinates

When drawing use #w and #h for actual size

Use #pop after drawing

Defined in:

Constructors

• .new(w, h)
• .new(wh : Tuple(Int32, Int32))

• #[]=(i, j, val : Char)
• #[]=(i, j, str : String)

  Draw a string str

• #[]?(i, j) : Cell | Nil
• #centre(mid, j, str : String)
• #centre(j, str)
• #circle(x0 : Int32, y0 : Int32, radius : Int32 = 5, ch : Char = '█', debug = false)

  Draws a polygon with points specified as an array of coordinate tuples

• #pop : self

  Pop offsets from stack

• #print(i, j, str : String)
• #push(new_x, new_y, new_w = Int32::MAX, new_h = Int32::MAX) : self
