Re: [Qgis-developer] Building plugin for Print Composer
We have talked a lot with Nyall about this. It was a requirement for a work I was developing some months ago (it's what I was describing some emails ago in this thead). I suppose the work Nyall is talking about is the deep refactoring of the Composer which will converge in the Report engine (QGIS 3.x), is it right? giovanni 2015-08-08 11:19 GMT+02:00 Nyall Dawson nyall.daw...@gmail.com: On 7 Aug 2015 6:58 pm, Vincent Mora vincent.m...@oslandia.com wrote: Hi all, I need to add graphs generated by a plugin to compositions.

Re: [Qgis-developer] Building plugin for Print Composer
Hi Jacob. For the moment it isn't possible to extend the Composer with custom plugins. It's sonething that will be discussed for the next Report Engine (QGIS 3.0) I've built a Python plugin that uses the composer widgets (composition, items, etc.) within a custom interface but you can only use the building blocks by yourself. E.g. you can open/create abd manage a composition inside your own widget and add items to it. In your case they could be text or html items, for header and footer. giovanni Il 22/giu/2015 15:18, Jakob Lanstorp jlanst...@gmail.com ha scritto: Is it possibly to build a Python plugin minded for the print composer alone? -Need to build a plugin with a new button inside print composer that lists all labels in the composer in a new dialog for editing.
