This is an upgrade of OJ behaviour when it is closed "before saving the
project file", *in italics my comments*:
a) Open OJ and *load a vector* layer. Than close OJ.
OJ shuts down with no warning to save the project.
*This is a bit ambiguous as an user wants maybe only to loads vectors with
no need do perform analysis. But only to have a project already set*. I*n
my opinion OJ should anyhow warns users if save the project*
b) Open OJ and *create a vector* file, Than close OJ.
There are two types of warning according to what happens:
- if the new layer is only created OJ warns that an automatically generated
layer is not saved
- if the new file is created and modified (ex. adding a feature), OJ warns
that one (or more) datasets has been modified.
*This is OK. We probably can extend both warning dialog adding a list of
the name of unsaved/modified layers*
c) Open OJ and l*oad a Sextante Raster* Layer. Than close OJ
See OJ behaviour and comments at point a)
d) Open OJ, load a Sextante Raster Layer, than *create a new Sextante
Raster* layer using Sextante Toolbox or other OJ tools. Than Close OJ.
OJ shuts down with no no warning to save the project.
*This is fatal for users who are not aware about it, as they can loose all
their work. We should add a warning message, like in point b) to add users
that 1d) new raster layers have been created, 2d) these layers are
temporary layers (they are saved into OS temp folder, users can lost them
if they shut down the computer)*
e) Open OJ and *load a WMS* Layer. Than close OJ
See OJ behaviour and comments at point a)
My conclusion:
1) I think we need anyhow a warning message that ask user to save the
project (see point a, c and e)
2) extend the warning message for the presence of "temporary raster layer"
and to save them (point d)
3) possibly add to this warning message a list of a) modified vector
layers, b) new vector layers, c) temporary raster layers (point b and d)
