[Qgis-developer] QEP about Multimap support for QGIS

[A Huarte]

Thank you very much Filipe!
The extra maps are normal windows as any dockable window in QGIS. It is a QDockWidget object, and your behavior is as usual.

Hi,
Really nice feature in my opinion. Out of curiosity: would it be possible to split Map 1 and Map 2 between two different screens? It would be really nice to be able to drag Map 2's window to a second screen.
Thanks
Cheers

Hi devs, I have developed an experimental code to support more than one map in QGIS. I created a video showing the features implemented ( https://vimeo.com/179982647 ).
The main features are:
   
   - New user option to enable multi map canvas mode.   

   - QGIS has one no closeable default map, and 0-N extra dockable maps.   

   - Full integration of maps in legend using a new map legend node for each map.   

   - Print composer supports layouts with different maps.   

   - New legend menu option to synchronize the extent of maps.   

   - Map tools and plugins work with the current selected map (The signals and slots to the map canvas are updated with an automatic mechanism of synchronization to minimize the migration of code and to preserve behavior).   


I'm aware that this is a big change in QGIS, and I am sure that this capability must be debated by many people (project and developer leaders...) before writing any code. Because of that, I have not created any QEP entry in the https://github.com/qgis/ QGIS-Enhancement-Proposals  page. 
I developed it to learn QGIS core and it will have work to do (plugins and tools). But it runs fine, and it was funny :-). If at least, it is useful for a day to implement this capability in QGIS or to see the amount of changes needed, I am satisfied.
