[Qt-interest] memory problem

[Sujan Dasmahapatra]

item[count] = new QTableWidgetItem(filename,0);
Whats wrong in this ?

fileNameUpdate() is called in some other function where I am getting the QString filename and a geometry,i.e Geometry * geometry and setting that geometry to geometry[count] = geometry;

This part is correct could u check annone what I am doing in the destuctor is correct or not ???

Kind Regards,
Sujan Dasmahapatra

Hi,

QList <QTableWidget *> item;
then:
Item[count] = new QTableWidgetItem(filename,0);
What the ... ???
And what's the point of this line: geoMetry = geometry;
What kind of value do you pass to the fileNameUpdate() function ?
Anyhow, most parts of your code are either weird, or incorrect.

Regards,

Alex
