The method ``_register`` should be called as widgets are added, and external code should call ``connect`` to associate callbacks. By default, all signals emit a DEBUG logging statement. signalsslotscCsd|_i|_i|_|dS)NF)_ignoring_events_sigs_map_setupselfrI/var/www/html/Darija-Ai-API/env/lib/python3.8/site-packages/fsspec/gui.py__init__%szSigSlot.__init__cCstj|_dS)z(Create GUI elements and register signalsN)pnZpaneZPaneBasepanelrrrrr+szSigSlot._setupvalueFcCs||jkrtd||g||d|j|<d|dk rFt|dt|nd|g}||j|<|dk rv|jj|j |dd|rt ||r| |t||dS) aWatch the given attribute of a widget and assign it a named event This is normally called at the time a widget is instantiated, in the class which owns it.
