Detailed Description

Widget to edit 3x3 matrices in plain text.

Author:

David C. Lonie

TextMatrixEditor is a QTextEdit that displays and allows editing of a 3x3 matrix as plain text. Input is validated with each keystroke, and the text turns red if the input is invalid. The matrix can be set/get with matrix() and setMatrix(). The delimiters used to separate columns can be set and accessed through the pointer returned by delimiters(). The default delimiter regexp is QRegExp("\\s+|,|;|\\||\[|\]|\\{|\\}|\(|\)|\\&|/|<|>"). resetMatrix() will replace the text with the last known good matrix.

[protected, slot]

Check if input can be parsed. Sets m_matrix, emits isValid(), and returns true if so. Otherwise emits isInvalid() and returns false.
