I have a floating NSPanel that is non-activating, i.e. its styleMask
contains the NSNonactivatingPanelMask
flag. Since this panel never becomes active, the system does not show the usual resize cursors when getting close to one of the panel's edges.
Is there a way to get those resize cursors to show up for a non-activating panel? E.g. the system's font panel pulls this off somehow.
