Re: [Qgis-user] Change properties of multiple layer at once

Hi,

thanks for the tip!

The layers are all of the same type (content is the same, they represent different days).

I wanted to preserve the different fill colors and just change the opacity and pen stroke.

Therefore copy stlye does not work.

Anyway, I adjusted the layers manually meanwhile - was just curious if there is an elegant way to do this and save time next time.

Regards,

Roland

May you change the style itself and set the same style to all layers.

You can change i.e. color of lines by "type of line" / attribute values
so you can use one style for multiple layers.
