Hi,
in the documentation, at the QgsProject entry, I read this:
bool read (QFileInfo const &file)
read project file
bool read ()
presuming that the caller has already reset the map canvas, map
registry, and legend
the first read (QFileInfo const &file) sets the project filename and calls
the second read (). As you read, it says: "presuming that the caller has
already reset the map canvas, map registry, and legend", so I wanted to use
it to append my QGIS project file to current.
But it doesn't happen: current maplayers are cleared and substituted to the
layers of the project file, althrough I still see the old project title in
the window titlebar.
Maybe it's a bug?
Here's how you can reproduce it:
write a plugin with this code:
QgsProject.instance().read ( QFileInfo ( "<path of a qgis file>" ) )_______________________________________________
