I know that I can write custom text to message bar with the
QgsMessageBar.pushMessage() method. But if I understand the documentation right, there's no room for variables added to a string where they are escaped (like in
print() function), and I get "arguments did not match any overloaded call" error when I try to call it like this. I want to print some variables for debugging my new plugin. How can I print them from the plugin's gui dialog? If message bar is not an option, how to do it?
I want to test how the plugin interacts with my QGIS plugin controls, so printing the values in Python console is not enough for me, though it's generally better for debugging.
