TuiScreen.Back

Returns the buffer being drawn into, so a test can read its cells.

Syntax

TuiScreen.Back( ) as TuiBuffer ptr

Description

The buffer being drawn into. Reading cells out of it is how you assert what a View produced, with no terminal involved.

Example

#import "std/tui"
using tui

dim as TuiScreen scr
scr.Resize( 20, 3 )
dim as TuiFrame ptr f = scr.BeginFrame( )
f->DrawText( 2, 1, "hi", TuiStyleOf( TuiRed( ), TuiDefaultColor( ) ) )

print scr.Back( )->At( 2, 1 )->st.fg.Index( )      '' 1 -- red, as asked
