[Qgis-developer] Recent changes to legend

[Tom Elwertowski]

I agree that the added columns make the legend unwieldy. Adding the 
icons is useful but the layout should be cleaner.

The "Label" caption and primary row of each layer should be full table 
width. The "Ov" and "Ed" labels aren't very meaningful when the icons 
aren't visible. Is Ed someone who pops up to help confused users? :) The 
layer names shouldn't be truncated for things which appear only in lower 
rows.

Rather than using separate top-level columns, I would just append icons 
at the end of lower rows as needed. To explain the icons, I'd use the 
yellow roll-over tooltips.

If the icons are used, they should also appear on the second row of the 
layer. When there is only one file, the icons are the same as the file 
row. For multiple files, there needs to be tri-state versions of the 
icons like the dashed and checked version of checkboxes. For example, a 
pencil icon drawn with dashed rather then solid lines would indicate 
that a layer had multiple files, only some of which are editable.

For 0.8, we should either do some additional work now to improve the 
layout or else postpone this until later.
