  • Ctrl + B: Same as Left Arrow, move the caret one character left

  • Ctrl + P: Same as Up Arrow, move the caret to the previous line

false

Setter

If any input text is truncated, the text_change_rejected signal is emitted with the truncated substring as parameter.

Example:

text = "Hello world"
max_length = 5
# `text` becomes "Hello".
max_length = 10
text += " goodbye"
# `text` becomes "Hello good".
# `text_change_rejected` is emitted with "bye" as parameter.
