I have 4 focus areas on a map… They are categorized by name, but the symbology is the same for all 4. When I add them to the print composer only the first 3 focus areas show up in the legend…
I'd like all 4 to be there as I want to have the focus areas named in the legend.
See attached screenshot.
Finally I found the answer : using the QgsLegendModelV2()class, and its functions inherited from QgsLayerTreeModel : "index(i,j)" to select each legend item and "rowcount" to obtain the rows number. All in a "for x in xrange" loop.
That gives:
for i in self.composition.items():
if isinstance(i,QgsComposerLegend):
legend = i
for i in xrange(legend.modelV2().rowCount()):
posteleg=legend.modelV2().index(i, 0)
print posteleg.data()

In the print composer, you are able to control the contents of the legend by turning off the Auto Update. (The Checkbox in the upper left hand corner of the legend control window above the layer list)
Then after that box is unchecked Click on the Blue Funnel to instruct the print composer to only display the currently displayed layers.
You can then use the "-" button to hide other layers of your choosing.
I have highlighted the Background image here with the palette.
I then click on the "-" button beneath the layer list to remove that layer from the legend.
That is how it works for me.

Do you have the 'Filter Legend By Map Content' turned on - this would filter out the subareas in your legend if they are not in the view of your map. If not, try clicking the update all button in the legend properties.
Personally if you are going to symbolise each area the same I would just have them symbolised as a single symbol rather than categorical. Then label the subareas appropriately in the map itself. As they are currently, the reader cannot derive any meaning from those categories when reading the map.
