Tooltip according to text background color or some other idea?

[abbassi]

Dear all,

I am creating a main window and then putting a textbox there in my form. and then this is what I am trying to do as it was mentioned "here":http://qt-project.org/faq/answer/how_can_i_display_a_tooltip_over_only_one_word_in_a_qlabel and I am not getting any tooltip.

@
ui->recvEdit->append("CHECK\n");
if (event->type() == QEvent::ToolTip)
{
QHelpEvent* helpEvent = static_cast <QHelpEvent*>(event);
QTextCursor cursor = ui->recvEdit->cursorForPosition(helpEvent->pos());
cursor.select(QTextCursor::WordUnderCursor);
if (cursor.selectedText() == "CHECK")
QToolTip::showText(helpEvent->globalPos(), cursor.selectedText());
}
@

Also is it possible that i can use compare the font color or background color of my word instead of word.

Do you get any text at all from the cursor? Are the coordinates correct? You will probably need to translate from global to local coordinates.

Thank you very much for the reply.
No I am not getting any text as tooltip.
I think they are correct because I am taking the current position of the cursor according to code.
If you mean instead of passing in
@ QToolTip::showText(helpEvent->globalPos(), cursor.selectedText());}@

i should try passing local then i also did that but same result.

here is the original code from where I am getting the idea. Maybe it will give you better understanding that what I am trying to achieve here.

@#include <QtGui>

class TextEdit : public QTextEdit
{
Q_OBJECT
public:
TextEdit(QWidget *parent) : QTextEdit(parent)
{
setTextInteractionFlags(Qt::TextBrowserInteraction);
setFrameStyle(QFrame::NoFrame);
setVerticalScrollBarPolicy(Qt::ScrollBarAlwaysOff);
setHorizontalScrollBarPolicy(Qt::ScrollBarAlwaysOff);
setText("This application only provides a tooltip for the following word: polymorphism");
QPalette pal = palette();
pal.setColor(QPalette::Base, QColor(1, 0.941176, 0.941176, 0.941176) );
setReadOnly(true);
setPalette(pal);
setFixedHeight(18);
setFixedWidth(400);
setSizePolicy(QSizePolicy::Fixed, QSizePolicy::Fixed);

    }

    bool event(QEvent* event) {
            if (event->type() == QEvent::ToolTip)
            {
                    QHelpEvent* helpEvent = static_cast <QHelpEvent*>(event);
                    QTextCursor cursor = cursorForPosition(helpEvent->pos());
                    cursor.select(QTextCursor::WordUnderCursor);
                    if (cursor.selectedText().startsWith("po" ))
                        QToolTip::showText(helpEvent->globalPos(), "Polymorphism");
                    else
                            QToolTip::hideText();
                    return true;
            }

            return QTextEdit::event(event);
    }

};@

What i want is to use this
@bool event(QEvent* event) {}@

function in my code where i've already a textedit using form ui.
Thanks in advance for the help.
