[Qgis-developer] Legend menus unification

[Marco Hugentobler]

Hi Martin,

> - disable ambiguous menu items in legend
> - use tristate checkboxes for toggle actions

In my opinion, tristate checkboxes have the advantage that it is still 
possible to enable/disable a property for all layer files in one go, even if 
there are several layer files in one layer.
On the other hand they may cause more confusion to users.

Thus I would favor tristate for visibility (important to toggle for all layer 
files) and disabling for editing and attribute table if there are several 
layer files. I cannot imagine a use case where I want to toggle editing or 
attr. table for more than one layer file at once.

For me,  checkboxes/toggle are more intuitive.

cheers,
Marco
