[Qt-interest] Issue before release

[Sujan Dasmahapatra]

Dear Friends

My software version 1.1 is ready for release just one issue I have to
resolve before I release.My software is an engineering software where I
read various data file (points) and create a curve with those pointd and
display that on the screen.

I have a scene(QGraphicsScene) and a view(QGraphicsView) I have set that
scene on the view constructor.Now every time I load a new curve  I
simply add the curve into my scene.For some geometries the loading is
not proper....

Can somebody tell me what other  matters I  need to consider  for
loading my geometry on the screen and fitting it properly in the view???

I have followe these steps.

1.       Read the data file (set of points) - reading through file
dialog.

2.       Create a polyline with those data points which is a graphics
item(QGraphicsItem).......drawPolyline(points,numberofpoints)

3.       Add that graphics item into the scene(addItem).

4.       Fit the geometry in the view.(fitInView).

These 4 major steps I am executing  for loading a geometry on the
screen...I think I am missing somethingelse so for some cases they're
not being loaded properly in turn what happenes is not geometry is
visible or the geometry is somewhereelse on the screen/view I can't
see.Why this is happening can anyone please tell me.
