Tooltip Displaying on the wrong position

[nekkro-kvlt]

Hi all,

I have a weird issue. I'm trying to display a tooltip on a QPlainTextEdit subclass, and the tooltip is shown too much above the mouse cursor. I'm currently showing the word under the mouse cursor. I basically used the code here:
http://developer.qt.nokia.com/faq/an...rd_in_a_qlabel

bool logEditor::event(QEvent *event)
{
    if (event->type() == QEvent::ToolTip)
        {
                processTooltip(static_cast <QHelpEvent*>(event)->pos(),static_cast <QHelpEvent*>(event)->globalPos());
                return true;
        }
 
        return QPlainTextEdit::event(event);
}
 
void logEditor::processTooltip(QPoint pos, QPoint globalpos)
{
    QPoint adjustedPos=pos;
    adjustedPos.setX(adjustedPos.x()-lineNumberAreaWidth());
    QTextCursor cursor = cursorForPosition(adjustedPos);
    cursor.select(QTextCursor::WordUnderCursor);
    QToolTip::showText(globalpos, cursor.selectedText());
 
}

bool logEditor::event(QEvent *event)
{
    if (event->type() == QEvent::ToolTip)
        {
                processTooltip(static_cast <QHelpEvent*>(event)->pos(),static_cast <QHelpEvent*>(event)->globalPos());
                return true;
        }

        return QPlainTextEdit::event(event);
}

void logEditor::processTooltip(QPoint pos, QPoint globalpos)
{
    QPoint adjustedPos=pos;
    adjustedPos.setX(adjustedPos.x()-lineNumberAreaWidth());
    QTextCursor cursor = cursorForPosition(adjustedPos);
    cursor.select(QTextCursor::WordUnderCursor);
    QToolTip::showText(globalpos, cursor.selectedText());

}

To copy to clipboard, switch view to plain text mode 

And see the result:

The word displayed is the correct word, but the position is wrong...

I'm not sure I understand what the problem is. From your screen shot it looks like the toolTip is shown in the standard position.

. . . but the position is wrong...

You can adjust the position. See QPoint::rx(). For example, to move it closer to the cursor vertically try this in processTootip():

globalpos.ry() -= 5

globalpos.ry() -= 5

To copy to clipboard, switch view to plain text mode

Yes I know I can adjust it, but I was just wondering if i was doing something wrong, since afaik the global pos of the event should be right under the cursor ... Here I have a space of approx 1 cursor between the cursor and the tooltip...

Also, do you know how to reduce the delay for the tooltip to show ?

Thanks

From QToolTip::showText():

The tool tip will be shown with a platform specific offset from this point of interest.

And from the source code:

QPoint p = pos;
    p += QPoint(2,
#ifdef Q_WS_WIN
                21
#else
                16
#endif
        );

QPoint p = pos;
    p += QPoint(2,
#ifdef Q_WS_WIN
                21
#else
                16
#endif
        );

Sorry, can't help with that.
