MessageLevel in QGIS3












5















I am trying to migrate a plugin to QGIS3 from QGIS2 and I am having issues with an API.



The original python has QgsMessageBar.MessageLevel but https://qgis.org/api/api_break.html says it has been moved to Qgis::MessageLevel. I tried replacing it in the code and got an invalid syntax and I couldn't find a MessageLevel example in py3.



What does it mean when something has been moved to Qgis::...? How do I find the proper syntax and use?






qgis qgis-3 python-3

The proper syntax is like below:



# First import Qgis class

from qgis.core import Qgis



...



def something():

    # Then you have to use like 'Qgis.MessageLevel' (Qgis.Info as an example)

    iface.messageBar().pushMessage(text, level=Qgis.Info)


For more information, please review Communicating with the user and QGIS API Documentation.

    You can make a util function like this,



    from qgis.core import Qgis as QGis
    

    
def showUserMessage(before, text="", level=QGis.Info, duration=3):
    
        ''' Show user info/warning/error messages '''
    
        iface.messageBar().popWidget()
    
        iface.messageBar().pushMessage(before, text, level=level, duration=duration)
    
        return
    

    
showUserMessage( "Info : ", "Info Sample")
    
showUserMessage( "Warning :", "Warning Sample",QGis.Warning)
    
showUserMessage( "Critical : ", "Critical Sample", QGis.Critical)

                      Is this a new Fibonacci Identity?

                      Image
                      6 1 $begingroup$ I have found the following Fibonacci Identity (and proved it). If $F_n$ denotes the nth Fibonacci Number, we have the following identity begin{equation} F_{n-r+h}F_{n+k+g+1} - F_{n-r+g}F_{n+k+h+1} = (-1)^{n+r+h+1} F_{g-h}F_{k+r+1} end{equation} where $F_1 = F_2 = 1$ , $r leq n$ , $h leq g$ , and $n, g, k in mathbb{N}$ . It is not too hard to show that this identity subsumes Cassini's Identity, Catalan's Identity, Vajda's Idenity, and d'Ocagne's identity to name a few. I have done a pretty thorough literature review, and I have not found anything like this, but I am still wondering if anyone has seen this identity before? I found this by accident after noticing some patterns in some analysis work I was doing, so if this is already known I would be curious to see w
