(SOLVED) QTextEdit subscripted text

[giowck]

Hi,
I'm writing a simple text editor (rich text with html as engine), so i use the QTextEdit class wich is really great... So far bold, italic, underline, alignments etc... work great.

Now I'm trying to allow subscript and superscript text.
The problem is that it doesn't work:

ui->htmlTextEdit->currentCharFormat().setVerticalAlignment(QTextCharFormat::AlignSubScript);

ui->htmlTextEdit->currentCharFormat().setVerticalAlignment(QTextCharFormat::AlignSubScript);

To copy to clipboard, switch view to plain text mode 

Nothing happens... Anyone?

BTW. i also tried with this:

QString selected_text = ui->htmlTextEdit->textCursor().selectedText();
ui->htmlTextEdit->textCursor().removeSelectedText();
ui->htmlTextEdit->insertHtml(QString("<sub>%1</sub>").arg(selected_text));

QString selected_text = ui->htmlTextEdit->textCursor().selectedText();
ui->htmlTextEdit->textCursor().removeSelectedText();
ui->htmlTextEdit->insertHtml(QString("<sub>%1</sub>").arg(selected_text));

To copy to clipboard, switch view to plain text mode 

The last one works, except that i can use it only when text is selected (QTextEdit has selection).

Thanks!

This works for me:

#include <QtGui>
 
int main(int argc, char **argv){
  QApplication app(argc, argv);
  QTextEdit edit;
  QTextDocument *doc = edit.document();
  QTextCursor cursor(doc);
  cursor.insertText("abc");
  QTextCharFormat fmt;
  fmt.setVerticalAlignment(QTextCharFormat::AlignSubScript);
  cursor.insertText("xyz", fmt);
  edit.show();
  return app.exec();
};

#include <QtGui>

int main(int argc, char **argv){
  QApplication app(argc, argv);
  QTextEdit edit;
  QTextDocument *doc = edit.document();
  QTextCursor cursor(doc);
  cursor.insertText("abc");
  QTextCharFormat fmt;
  fmt.setVerticalAlignment(QTextCharFormat::AlignSubScript);
  cursor.insertText("xyz", fmt);
  edit.show();
  return app.exec();
};

I think you are modifying a copy of the format. currentTextCharFormat() returns a copy and not a reference so your changes are not applied to the cursor.

Oh thank you!

I thought it were a reference xD

Now it works!
