So, i tried to make scrolling faster with Alt pressed, and it gives me either the strangest, or the dumbest error ever: dcurrent_value = current_value % scroll_amount # Snapping to nearest step (current value is any number, while accumulated scroll is fixed to steps) ~~~~~~~~~~~~~~^~~~~~~~~~~~~~~ ZeroDivisionError: integer modulo by zero At first i thought the problem was with step_size, but after a bit of testing it was not it. Then i tried to change & to is/in/==, didnt work either. So i just added another modifier, Shift, and it started working just fine. Whats up with AltModifier? def wheelEvent(self, event): modifiers = event.modifiers() if modifiers & Qt.KeyboardModifier.AltModifier: # Use == instead of & step_size = self.step_size * self.alt_multiplier elif modifiers & Qt.KeyboardModifier.ShiftModifier: # Keep & for Shift since it works step_size = self.step_size * self.alt_multiplier else: step_size = self.step_size delta = event.angleDelta().y() scroll_amount = round(-delta / 120 * step_size * self.scale_multiplier) # Float error # Reset or accumulate scroll based on direction change if self.prev_delta != delta: self.accumulated_scroll = 0 self.accumulated_scroll += scroll_amount current_value = self.scroll_bar.value() dcurrent_value = current_value % scroll_amount # Snapping to nearest step (current value is any number, while accumulated scroll is fixed to steps) Continue reading...
