How to add text to a Qplaintextedit(PYQT5)

Question

At first I would just like to know how to add values in a Textedit, however my goal is to take the values of the two comboBoxs and use them to generate the password.

Follow the code:

# -*- coding: utf-8 -*-

# Form implementation generated from reading ui file 'GestorDeSenhas.ui'
#
# Created by: PyQt5 UI code generator 5.6

Answer 1

The Widget PlainTextEdit has associated with it an object of the type QTextDocument - is this object that has the methods and attributes both to read the user’s typed content, or to change the content, or to configure the presentation. (Already aspects like cursor location, width of the same, are configured directly in the object QPlainTextEdit)

The method .document() returns this object associated with the editor, which in turn has the method .setHtml() which allows you to insert the desired content in the editor. You can send a string with any valid HTML, including inline style - Qt will automatically translate your HTML to the style it uses internally (text-formatted extensions use the tag <span ...>, even if they are sent with the tag <h1>, for example).

So in your case, you could just do, at the desired point:

doc = self.txtBoxresultado.document()
doc.setHtml("""<h1>Senhas Geradas:</h1>abc123<br/>qazwsx<br/>123456<br/>""")

And here’s the tip for the next time you ask a question: Reduce your code to only contain what you need to solve - a minimal, self-contained, verifiable example - that is, that anyone with Pyqt5 installed can copy and run, and that has only the window and the Texteditor. Sending the question this way you force people to study your entire program, to take a question just punctual.
