[Qt-interest] Delete Items Problem

[Sujan Dasmahapatra]

Dear Friends 

I am facing a problem very serious.I  am developing an engineering tool
where I am loading multiple geometries one by one.At the same time I
have a QTableWidget and I am loading  correspondingly the geometry file
names in the QTableWidget as QTableWidgetItem.

 

Now  after loading some 3 or 4 geometries if delete the last item
everythings is fine.But if I delete the first item then some problem is
happening so that I am not able select the geometry again from the
QTableWdiget as its crashing.

 

You can see this peace of code. Yo can see these two functions
mouseReleaseEvent is there for selecting geometry from the TableWdiget
and delete part is the mechanism by which I am deleteing parts.......

I am doubting something do I need to refresh the QTableWidget after I
delete an item from QTableWdiget.Please help any one  to fix this bug ..

 

 

void TableWidget::mouseReleaseEvent(QMouseEvent * )

{

        if(countTableWidget>=1)

        {

        if(item[currentRow()]->isSelected()==true)

        {

                if(countTableWidget != 1) {

                for(i=0;i<countTableWidget;i++)

                {

                        if(geoMetry[i]->isSelected()==true)

                        {

 
geoMetry[i]->setFlag(QGraphicsItem::ItemIsSelectable,false);

                                geoMetry[i]->setSelected(false);

 

                        }

                }

                }

                selectPart();

        }

        }

}

 

void TableWidget::deletePart()

{

        if(geoMetry[currentRow()]->isSelected() == true)

        {

        delete geoMetry[currentRow()];

        removeRow(currentRow());

        countTableWidget--;

        if(countTableWidget==0)

                {

                        geoMetry.clear();

                        item.clear();

                }

 

        }

}
