QT textedit enable

To enable a QTextEdit in a Qt application, you can follow these steps:

1. Add a QTextEdit widget to your application's user interface using Qt Designer or programmatically.

2. In your code, you can set the text content of the QTextEdit using the setText() function, like this:

   ui->textEdit->setText("Hello, world!");

3. You can also enable or disable the QTextEdit using the setEnabled() function, like this:

   ui->textEdit->setEnabled(true);  // Enable the QTextEdit

or

   ui->textEdit->setEnabled(false);  // Disable the QTextEdit

Note that disabling a QTextEdit will also disable any user input and make the text color grayed out.
