Cura Preferences Instability with Plugin


Recommended Posts

Posted · Cura Preferences Instability with Plugin

I'm having some issues with stability of the preferences in my cura plugin and have a couple questions:


Are all preferences that are set stored in the cura.cfg file? 


As I understand it I only need to run the addPreference() function once and then from then on I can setValue() whenever I need but otherwise the preferences should stay in cura right? Is there a save script or something else I need to do to ensure that the preference stays? 


Can the addPreference script only be run on initial install? It kinda seems like only the addPreference scripts I run on the initial install of my plugin are actually getting saved to cura.cfg and the rest never actually appear

    The addPreference method has to be run each time Cura starts, before you access the preference with getValue/setValue.


    Saving the preference values to file is done automatically. You don't have to tell Cura to do so.


    If you use setValue to set the preference to its default value, the value may be remove from the cura.cfg file. But since you must specify that default on each startup of Cura with the addPreference method, this works fine; if there is no value in cura.cfg, then the default value is used.
