add_to_console_backlog(variables)

Save variables for pushing to console when it is instantiated.

This function will create weakrefs when possible to avoid holding on to too much memory unnecessarily.

Parameters:

variables (dict, str or list/tuple of str) – The variables to inject into the console’s namespace. If a dict, a simple update is done. If a str, the string is assumed to have variable names separated by spaces. A list/tuple of str can also be used to give the variable names. If just the variable names are give (list/tuple/str) then the variable values looked up in the callers frame.

dragEnterEvent(event)

Ignore event if not dragging & dropping a file or URL to open.

Using event.ignore() here allows the event to pass through the parent widget to its child widget, otherwise the parent widget would catch the event and not pass it on to the child widget.

Parameters:

For each file, attempt to open with existing associated reader (if available). If no reader is associated or opening fails, and more than one reader is available, open dialog and ask user to choose among available readers. User can choose to persist this choice.

Parameters:

event (qtpy.QtCore.QDropEvent) – Event from the Qt context.
