[Qt-interest] Screen is getting white

[Sujan Dasmahapatra]

Dear Friends 

I have developed a software where I am loading multiple geometries one
by one and it's appearing on the screen  as well as the file name is
being updated in my QtableWidget. But I do't know why sometimes the
screen is getting white and no geometry is visible.I fixed the scene
background  color as black so there's no reason for it to get white.
After analyzing the problem I came to know that the geometry is actually
being uploaded but the screen is getting white and the geometry is not
visible.But if I continue the operation and  if I load another geometry
then all the geomries are visible.I don't know why it's sometimes
getting white and invisible.

Could anyone tell me the possible reason.Here I am writing the code
which is managing my Scene and View.

Please help me 

     

 

     scene->addItem(geometry[countMainWindow]);

     tableWidget->fileNameUpdate(fileGeometry[countMainWindow],
geometry[countMainWindow]);

     view->fitInView(geometry[countMainWindow],Qt::KeepAspectRatio);
//This two functions are fitting the geometry on the view

     view->setSceneRect(xmin,-ymax,width,height);

     view->show();

     statusBar()->showMessage(tr("Part loaded"),2000);

     consoleView->append(fileGeometry[countMainWindow] + " is loaded");

     countMainWindow++;

     firstTime = false;
