Bonjour Michaël,
thanks for the answer and the notes/questions.
I don't understand the reason for such a change. Copy schema/Paste schema
operations are relative to a layer.
How will you copy a schema from a layer to another layer ? Will you have to
open the schema dialog of the source layer, copy, close the dialog, open
the schema dialog of the target layer and paste ? Or will it be possible to
have both source and target schema opened at the same time ? And will you
be able to paste a schema to several layers ?
The idea is to simplify the layer context menu and have all Schema
plugins/actions on the Schema panel toolbar.
I figure out that an User should a) open source layer schema panel, b)
click on "Copy schema" button (*), c) open a target layer, d) click on
"Paste schema" button(*).
Cons: this process is slower than clicking Copy/Paste plugins on layer
context menu.
Pros: User can control if copy, and specially paste, actions have been
finalized in the right way(**): By the time that the User clicks on the
Paste schema button, the schema is applied to the layer
Currently the actions (both Copy/Paste schema plugins on the layer context
menu, and the toolbar button) work on one layer per time.
Right now, once a Schema has been copied on the clipboard, it is possible
to paste to several layers (again one layer per time)(***).
On the other hand, adding a way to save/restore a schema from a file can be
a useful addition.
Ideally I wanted to create a simple Load schema plugin which would have
retrive Schema from a dbf or jml file. Then I realized that there were so
many extra vector options (GeoJSON, DXF, CSV,...) that the work would bhave
been quite long. Saving to a text file and loading seems to me a valid
simple alternative.
I use schema editor quite much and I often have hesitated to add the plugin
in the toolbar, but this is another (easier) question.
My alternative proposal is to keep both options on a Layer context schema
submenu:
a) an enhanced View/Edit schema plugin with all the Copy/Paste/Save/Restore
options and
b) both Copy Schema and Paste Schema plugins.
Best regards
Peppe
(*) Copy/Paster schema buttons (on schema toolbar) actions do not refer to
extra codes: they simply l run CopySchemaPlugIn and PasteSchemaPlugIn
(**) Yesterday, the firt time I used the new Schema panel copy/paste
schema,I realized (and then corrected) that Paste schema former plugin was
missing of Boolean and Long attributes.
(***) Paste Schema prevents to clone the same attributes (same name, same
type) if clicked more times on the same layer. On the other hand this
plugin is not undoable - which should be solved...
