Finding a piece of text under cursor

[Shoto]

So I need to find a piece of text under cursor. Now here's the problem, I already solved it when the user clicks on a word but now I need to grab the word when the user hovers over the word. I'm using PyQt5 version 5.12.1 and python 3.7.

The method I used to get the word under cursor then user clicked is this:
Note: self is a class that inherits from QPlainTextEdit

textCursor = self.textCursor()
textCursor.select(QTextCursor.
print(textCursor.selectedText())

But now I wanna know how to get the same result without clicking

    def mouseMoveEvent(self, QMouseEvent):

        print(QMouseEvent.pos())

My QPlainTextEdit class has mouse tracking turned on but I don't know how to proceed from here.

@Shoto Hi,

This may help to achieve your goal (code is C++):

//in mouseMoveEvent
QTextCursor cursor = cursorForPosition(event.pos());
cursor.select(QTextCursor::WordUnderCursor);
//Retrieve text with cursor.selectedText()

@Gojir4 said in Finding a piece of text under cursor:

cursorForPosition

Thank you so much!

@Shoto Don't know for what you need that. But if this is for displaying a tooltip information about text under cursor, there is also another way to do it (sorry, C++ code again):

bool MyTextEdit::event(QEvent *e)
{
    if (e->type() == QEvent::ToolTip)
    {
        QHelpEvent* helpEvent = static_cast<QHelpEvent*>(e);
        QString txt = cursorForPosition(helpEvent.pos()).select(QTextCursor::WordUnderCursor);
        if(txt.isEmpty())
            return QPlainTextEdit::event(e);

        //Display tooltip at cursor position
        showToolTipForText(helpEvent->globalPos(), txt);

        return true;
    }
    return QPlainTextEdit::event(e);
}

Hmm. I'm creating an IDE and C++ code is perfectly readable for me, thanks
