[Bug]: "Toggle" setting in Layers tab on Lizmap QGIS plugin not working on groups

[mind84]

What is the bug?

Hi, the follow configuration on Lizmap plugin:

• group1 -> Toggle unchecked
• all children of group1 -> Toggle checked

seems not to be interpreted correctly by LWC

The tree should be initialized like this (?)

Thanks

The toggled option for groups was never taken into account. It was always the layers toggled state that fixed the group toggled state.

@rldhont,

As far as we can see, in 3.7 this functionality is changed and emulates the QGIS functionality. In previous versions the checkbox on groups is basically a shortcut to check or uncheck all of the group's children, and it's ok to not take into account the group configuration. In 3.7, instead, the group checkbox is used to enable/disable the group, exactly how it works within QGIS: when you uncheck the group, if some children are checked they remain checked but not displayed, so when you reactivate the group you don't have to uncheck the layers you don't want to display.

If this is the intended behaviour, the group configuration (enabled/disabled) at the Lizmap QGIS plugin becomes relevant.

I didn't follow the latest status here, but if there is a special behavior to do in the plugin when LWC 3.7 is used (and not previous versions of LWC), this can be added on the plugin side.

well, I do not get it either - in 3.6.X the behaviour was ok - When the group was toggeld (as user in LWC) all layers of this group get toggled as well. But now in 3.7 i have to activate each and every layer of my group, to get the whole bunch of layers shown on the map. Preferably the behaviour like in QGIS should be followed by LWC - layers of a group can be toggled, but as long as the group itself is not toggeld, the layers do not appear on the map.
