Class: Tuile::Component::IntegerField::Field

Inherits:
TextField show all
Defined in:
lib/tuile/component/integer_field.rb,
sig/tuile.rbs

Overview

The face: a TextField that admits only the buffers an integer can be typed through, however the characters arrive.

Constant Summary collapse

TYPEABLE =

Buffers reachable by typing an integer: an optional leading -, then digits. Looser than the parse on purpose — the half-typed "" and "-" are members, or no value could be typed at all, and Tuile::Component::IntegerField#value reads both back as nil.

Returns:

  • (Regexp) 
/\A-?\d*\z/

Constructor Details

This class inherits a constructor from Tuile::Component::TextField

Instance Method Details

#insert_text(str) ⇒ Boolean

Accepts the insertion only if the whole resulting buffer is still typeable, so "12abc34" is dropped rather than sieved into "1234".

@param str

@return — true if the text changed.

Parameters:

  • str (String)

Returns:

  • (Boolean)
