1.) Load a layer

2.) Choose unique value in symbology

3.) press classify

4.) assign several classes

Problem:

• in a polygon layer you can't change the fill color for the assigned classes

• in a line layer you can't change outline style, outline color, fill style and fill color

• in a point layer you can't change outline color, outline width and fill color

Also it seems as it depends on the kind of symbol you have selected what happens

After you have pressed the reset colors button everything works fine

Replying to "bjpfei":/issues/show/1703:

• in a line layer you can't change outline style, outline color, fill style and fill color

• in a point layer you can't change outline color, outline width and fill color

This is intentional. If you select multiple classes you can change only the
options that have a common value in all those classes.

OK I understand.

But I think there could be good reasons to change multiple classes with non common values.
eg you have some classes with dash lines and some with solid lines.
Now i want them all to have dot lines. OK I can change class by class individually.
But I don't think that this is very user-friendly.
So maybe one can think about implementing this enhancement.

thx

Hi Jurgen,

I maybe noticed a bug in the symbology but I don't know if it was there before applying this patch or if it was there before.

Take a layer (testing a few from the qgis dataset) and classify it with unique values using a field (ex. "cat"). Then select a few classes (but also one is enough) and change a property, apply.

At this point change the classification field (ex. "name") and click "classify": the result is that the old classes do not disappear and instead the new classes are added to the old list.

it is not really necessary to change a style option, in fact it is just enough to have one class selected and then, if you change the classification field, the old classes will remain together with the new ones.

I noticed also that in the unique values symbology, the values of numeric fields are ordered like strings. Don't know if this is really a bug.

Lutra, the new bug (old classes don't disappear) is also in QGis 1.1.
