I'm trying to manually move labels but having some trouble. I'm trying to move the labels while in edit mode. I've added fields for x coordinate (all null), y coordinate (all null), rotation (all =0), and font-size (all =10). This makes the "move label" and "rotate label" buttons active, but when I click on the labels, no box around the label appears and it's impossible to move the label. What am I doing wrong?
We found recently the same behaviour occurs when layer's alias have special character like "à , é, ë.. etc". If this is your case, just rename layer to a simple name. I will create a new bug entry for this in hub.qgis.org.
I assume that, you have not set enough space (field width) for the coordinates of the label (these are real numbers). I think the moving is not possible because of this.I encountered the same problem once.
At any rate: This problem was solved in a current thread: How to add labels outside of features? The new plugin automatically sets enough width in the field for the coordinates. Moving should be possible then.
