Bug report #15920

QLR file loading ignoring <widgetv2config> configuration, as opposed when loading from QGS

Category:Edit widget

Crashes QGIS or corrupts data:No Copied to github as #:23837


QGIS Layer Configuration includes information about edit widgets: edit widget type (Text Edit, Value Map, ...), constraints (Not null,...), editability, default values,...

When you "Save As Layer Definition file" you get a .qlr file with all this information.
But when you try to load this .qlr file ("Add from Layer Definition File"), all information about edit widgets is ignored, it is not restored.

By the way, when you save a QGIS project, you get a .qgs file, that also includes all this information. But opening the .qgs project do indeed correctly restores all edit widget information.

By opening both .qgs and .qlr files with a text editor, we have seen that they use the same schema format to describe all that information (under <maplayers><maplayer><edittypes><edittype><widgetv2config>). So it seems that processing this information should follow the same rules no matter if it is read from a QLR or a QGS file...

Knock knock,

This is really a LARGE issue for those of us, that uses qlr - functionality. Take a look at the QLR Browser plugin as an example.

I can possibly scrape some money from the the bottom of my budget allowance to fix this issue. Either this year. Or in the start of the next year.

I think Nathan was the original author of the qlr functionality. Why didn't you implement the widget creation together with styles ? Was there any difficulties or did you run out of time / resources ??

#2 Updated by Nathan Woodrow about 7 years ago

QLR files were intended to be just styles and label information at this time. In QGIS 3.0 I would like to split all this stuff out so you can have the option but at the time I didn't want widget information.

  • Target version set to Version 3.0

I do understand why you don't want to mess around with this request in ver. 2.18. But it would be very nice if it could make it into ver. 3.0 :-)
Send me an email regarding funding if it's necessary ()

End of life notice: QGIS 2.18 LTR


QGIS 3.4 has recently become our new Long Term Release (LTR) version. This is a major step in our history – a long term release version based on the massive updates, library upgrades and improvements that we carried out in the course of the 2.x to 3x upgrade cycle.

We strongly encourage all users who are currently using QGIS 2.18 LTR as their preferred QGIS release to migrate to QGIS 3.4. This new LTR version will receive regular bugfixes for at least one year. It also includes hundreds of new functions, usability improvements, bugfixes, and other goodies. See the relevant changelogs for a good sampling of all the new features that have gone into version 3.4

Most plugins have been either migrated or incorporated into the core QGIS code base.

We strongly discourage the continued use of QGIS 2.18 LTR as it is now officially unsupported, which means we’ll not provide any bug fix releases for it.

You should also note that we intend to close all bug tickets referring to the now obsolete LTR version. Original reporters will receive a notification of the ticket closure and are encouraged to check whether the issue persists in the new LTR, in which case they should reopen the ticket.

If you would like to better understand the QGIS release roadmap, check out our roadmap page! It outlines the schedule for upcoming releases and will help you plan your deployment of QGIS into an operational environment.

The development of QGIS 3.4 LTR has been made possible by the work of hundreds of volunteers, by the investments of companies, professionals, and administrations, and by continuous donations and financial support from many of you. We sincerely thank you all and encourage you to collaborate and support the project even more, for the long term improvement and sustainability of the QGIS project.
