Re: [Qgis-developer] multi-view
I started working on something similar the other day as I could not get this
patch to apply and thought about a different way of going about it.
The general idea is to use a QMdiArea(tabbed or floating) as the central
widget for QGisApp class. You can then create a new window using
QMdiArea.addSubWindow(QgsMapCanvas). You would then connect to the sub
window changed event to know when the user changed windows in order to
update the legend, undo stack, tool etc.
The general layout and rules are:
1. There is only one active canvas at a time.
2. The active canvas is stored in the mMapCanvas QgisApp variable. This
is updated when the user clicks on the map or tab eg on subWindowChanged
signal
3. When the user clicks a tool it sets the tool for the current canvas
active via. mMapCanvas.setMapTool({maptool} the map tools canvas is
updated using {maptool}.setCanvas(mMapCanvas). This means there is only one
instance of {mapTool} just it's canvas gets changed.
4. On subWindowChanged the legends canvas is updated to reflect the new
maps layers.
5. Opening a vector layer opens it in the curent active canvas.
6. Try a limit the amount of new code code added, try and use as much
that is already there.
7. Being able to switch between tabbed or floating windows would be very
powerful.
I know this is no easy task, no matter which way you run with it. And there
a lot of user cases which needed to be taken into account.
I was thinking about pushing what I have to git hub tonight if anyone is
interested.
Just my thoughts on the subject.

The patch was never applied due to main api change ? Hi Massimo the patch for tabbed interface has a lot of consequences. First of all it is important to answer what are the use cases for multiple canvases - what are pros and cons of such interface for both users and developers. For example, to what degree the individual map canvases should interact between each other - allow different sets of layers, allow different symbolization of layers, different projections, simultaneous editing of one layer in various canvases? From developer's point of view there are also many questions - should map canvases share the instances of layers or create duplicates, should a map tool be bound to one map canvas or handle all existing canvases? As you probably see, for a different set of use cases the answers would be different. The patch itself is long and doesn't come with any overview of the architecture. I would recommend you to start a RFC which can be discussed and modified to reach the consensus. Anyway a change like this looks to be more suitable for qgis 2.0 where we will be able to break API and thus implement things well. I have the same feelings for the split view modifications. First it's better to share and talk about the concept of bigger features in order to have clear way into trunk later.

Re: [Qgis-developer] multi-view
Hi Ludovic Looks nice. Yes, multi view is definitely of interest. If yes, i am interesting to know how to integrate this to official qgis code. The best thing is to create a patch that can be applied to the current trunk version (1.4 is a bit old now). Create a ticket in trac (http://trac.osgeo.org/qgis) , attach the patch and add a bit of textual description. It will then be review by the dev team. Regards, Marco Am Donnerstag, 13.

Hi Ludovic, nevermind .. your efforts are not lost beacouse the patch is old, it needs to be revisited and your work with multispectral analisys results can be fused with the addtab patch. just having it fixed to be able to apply it on the actual trunk .. should be a good first step it is also nice to have you intersted on multiview too, maybe this time we will finally have it implemented in qgis i like and use the multiview capability (like in grass). note, i was just a guinea pig (tester) for it :-) all the hard cpp work was made by LinxID All my thanks to Him! thanks!
