[Qgis-user] Refreshing user interface during script execution

[Patrick Dunford]

Good day

I have a script that runs a number of processing steps that take a long 
time to execute and during this execution the only way I can display 
progress messages is by printing to the Python scripting console.

I would prefer to be using the message bar to display the messages but 
the screen does not update meaning these messages are not displayed. 
They only get displayed if there is also a print statement sending 
output to the console. The other parts of the user interface also do not 
update.

Using the message interface like this:

iface.messageBar().pushMessageOr perhaps using the status bar 
iface.statusBarIface().showMessage("Processed {}%".format(int(percent))) 
They all have the same basic issue. I also want to know how I can 
interrupt the script execution when it is running, at the moment the 
only option I have is to kill the Qgis application.
