    Default Add some function to reimplement method

    Hi
    I want add:
    Qt Code:
    1. if( !anchorAt( e->pos() ).isEmpty() )
    2. QMessageBox::information(0,"",anchorAt( e->pos() ));
    To copy to clipboard, switch view to plain text mode 
    to orginal(default, not edited) method "mouseDoubleClickEvent" in qtextedit.

    If i make my own method
    Qt Code:
    1. void MyTextEdit::mouseDoubleClickEvent(QMouseEvent *e)
    2. {
    3. if( !anchorAt( e->pos() ).isEmpty() )
    4. QMessageBox::information(0,"",anchorAt( e->pos() ));
    5. }
    To copy to clipboard, switch view to plain text mode 
    then default(if you double click on char then selected all word) will be not work

    So if i want add(not edit) then i will be have to make somting like this
    Qt Code:
    1. void MyTextEdit::mouseDoubleClickEvent(QMouseEvent *e)
    2. {
    3. //i have to finde default code mouseDoubleClickEventand and past here
    4.  
    5. if( !anchorAt( e->pos() ).isEmpty() )
    6. QMessageBox::information(0,"",anchorAt( e->pos() ));
    7. }
    To copy to clipboard, switch view to plain text mode 

    Somebody know faster way to do this , without copy code from default method ??

    <facepalm/> Call the base class implementation... This is basic C++...

    No, you will not have to make a new method.

    Qt Code:
    1. void MyTextEdit::mouseDoubleClickEvent(QMouseEvent *e) {
    2. QTextEdit::mouseDoubleClickEvent(e);
    3. }
    To copy to clipboard, switch view to plain text mode
