Making a QTextEdit capital


I am trying to make all text in a QTextEdit capital, but currently am failing. This is my code and it does nothing.

void MainWindow::on_actionCapital_triggered()
{
    QTextCharFormat capital2;
    capital2.setFontCapitalization(QFont::AllUppercase);
    ui->textEdit->setCurrentCharFormat(capital2);
}

I am a java coder, so c++ is not my strong point

I also tried the following code with no success:

QFont font = ui->textEdit->font();
font.setCapitalization(QFont::AllUppercase);
ui->textEdit->setFont(font);

Can someone please point me to the right direction?


Solution

  • I figured it out not the most elegant solution, but it will do its job:

    void MainWindow::on_actionCapital_triggered()
    {
        QTextCursor c = ui->textEdit->textCursor();
        int current = c.position();
        if(capital)
        {
            QTextCharFormat capital2;
            capital2.setFontCapitalization(QFont::MixedCase);
            ui->textEdit->selectAll();
            ui->textEdit->setCurrentCharFormat(capital2);
            capital = false;
        }
        else
        {
            QTextCharFormat capital2;
            capital2.setFontCapitalization(QFont::AllUppercase);
            ui->textEdit->selectAll();
            ui->textEdit->setCurrentCharFormat(capital2);
            capital = true;
        }
        c = ui->textEdit->textCursor();
        c.setPosition(current);
        c.setPosition(current, QTextCursor::KeepAnchor);
        ui->textEdit->setTextCursor(c);
    }
    

    With this code you can switch between all Upper case and mixed case. For some reason the setCurrentCharFormat only works when the text is selected. So I had to get the current cursor position and then select all apply the FontCapitalization and then set the cursor back to where it was.
