In my Project, I have a Main Widget in that QWT Plot Widget and some other widgets [QList ..].
I can get the MouseMoveEvent of my MainWidget but not able to get QWTPlot MouseMoveEvent.

suggestion please

Qt Code:
  1. void MainPlot::mousePressEvent(QMouseEvent *event) // this is my MainWidget called MainPlot
  2. {
  3. ------
  4. ------
  5. }
To copy to clipboard, switch view to plain text mode 

and
my QWTPLOT Mouse Event is
Qt Code:
  1. void MainPlot::ui->uPlot->mouseMoveEvent(QMouseEvent *) // Uplot is my QWTPLOT widget
  2. {
  3. // some code
  4. ------------------
  5. -------------------
  6.  
  7. }
To copy to clipboard, switch view to plain text mode
