Hello Nicolas,
Well, yes it would be nice to hide the element/attributes completion widget
when completion is not possible.
When is completion basically not possible ?
They are around two cases when element/attributes name completion
is not possible:
1/when the current selected xml node is not valid
The current selected node can be in a non valid state if
either no DTD is present (neiter internal nor external subset)
or a DTD is present and the current selected node does not
validated against the DTD.
2/when the user has switched off the validation setting key
This implies that the "completion_is_possible" state is (in the worst case)
specific to each xml node of the document.
We could first the following API :
gboolean
MlViewXMLDocument::is_completion_possible (MlViewXMLDocument *a_this,
xmlNode *a_current_xml_node,
MlViewAppContext *a_ctxt) ;
It would obviously return TRUE if completion is possible, FALSE otherwise.
Then comes the hidding/showing of the completion widget.
Today, the completion widget is packed in a GtkHPaned widget.
Putting the gutter GtkHPaned at the extreme right hand side would hide
the completion widget.
But how to trigger the hidding/showing of the completion widget ?
As I said before, the "completion_is_possible" state is specific to each xml
node. So each time the user selects an xml node, we can just hide/show the
completion widget. To achieve this, we can connect to the
MlViewXMLDocument::node_selected signal (in MlViewTreeView::construct()),
test if completion is possible, and show/hide the completion widget accordingly.
Would this proposal suits you ?
Thank you for your time.
Cheers,
Dodji.
