Qt 4.3.0 - how to get text from a QTextEdit?!?!
Message 1 in thread
How do I get the text from a QTextEdit?
The two functions listed in the help won't compile:
'text' : is not a member of 'QTextEdit'
'plainText' : is not a member of 'QTextEdit'

I also scratched my head when I first looked at QTextEdit. You
have to use a QTextCursor. Here's some example code (without further
expaination) that I use to grab a line "near" the current cursor possition:
QString
OabConsole::getCommandLine()
{
QTextCursor lCursor = m_textEdit->textCursor();
// move to end of previous line
lCursor.movePosition(QTextCursor::PreviousCharacter,
QTextCursor::MoveAnchor,/*count*/1);
lCursor.movePosition(QTextCursor::StartOfLine,
QTextCursor::KeepAnchor,/*count*/1);
QString line = lCursor.selectedText();
//qcerr() << "line: '" << line << "'" << endl;
//qcerr() << "line unicode: ";
//IcmQT::debugOutQString(line,qcerr());
//remove prompt from front of line (if present)
if ( line.startsWith(m_normalPrompt) ) {
line = line.remove(/*starting*/0,/*amount*/m_normalPrompt.size());
return line;
}
if ( line.startsWith(m_continuePrompt) ) {
line = line.remove(/*starting*/0,/*amount*/m_continuePrompt.size());
}
return line;
}

Use toPlainText() to get the current text.
Use setPlainText() to set the text.
plainText is a property of the QTextEdit, which is you have to use
set/get methods to access this property.

plaintext property to see the accessor functions)

You might be looking at the help for 3.x. The functions you want are:
toPlainText()
toHtml()
