Hi all,
I already post this mail to [JUMP] lis SVN. I put here also for user who
are not involved on developing just to explore other opinion.
The test I did is on OpenJUMP 4508. This is a OJ behavior 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 and
save the project with no need do perform analysis .* 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 - (automatically generated warning)
- if the new file is created and modified (ex. adding a feature), OJ warns
that one (or more) datasets has been modified. - (modified warning)
*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 (no
vectors loaded/created).
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) warning 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 automatically generated warning to the presence of
"temporary raster layer" and to save them (see point d)
3) possibly add to the warning messages a list of a) modified vector
layers, b) new vector layers, c) temporary raster layers (see point b and d)
