    Hi,

    Can you explain with a simple example what your are trying to do ?
    From the description above it's tough to guess.



  • i have read sequence of image in a qvtkwidget and connected slider and spinbox to it so that wen i scroll my mouse i shud know the slice number.
    wen i move slider slices move bt i am struggling to connect it in reverse like wen my slices move with the scroll slider shud move bt which is nt happeneing.

    Good to hear the you solved your problem. You can post the solution here in brief words if possible so that in future someone would benefit from it. Also you can mark the post as solved.



  • @#include "ui_mainwindow.h"

    and in the interactor style class did as below
    Ui_MainWindow *_ui;

    void SetUi(Ui_MainWindow *ui)
    {
    _ui=ui;
    }

    void OnMouseWheelForward()
    {
    if(_Slice < Max_Slice)
    {
    _Slice += 1;
    Image_Viewer->SetSlice(_Slice);
    _ui->verticalSlider_2->setValue(_Slice);

         Image_Viewer->Render(); 
      }
    

    }

    and things work perfect.
