Struct Viewport

pub struct Viewport { /* private fields */ }

Implementations

impl Viewport

pub fn new(terminal_width: u16, terminal_height: u16) -> Self

Erstellt neuen Viewport mit sicheren Defaults

pub fn update_terminal_size(&mut self, width: u16, height: u16) -> bool

Aktualisiert Terminal-Größe und berechnet Layout neu

pub fn update_content_height(&mut self, new_content_height: usize)

✅ DEBUGGING: Content-Höhe Update mit detailliertem Logging

pub fn scroll_up(&mut self, lines: usize)

✅ DIREKTES SCROLL-UP mit besserer Kontrolle

pub fn scroll_down(&mut self, lines: usize)

✅ DIREKTES SCROLL-DOWN mit Auto-Scroll-Reaktivierung

pub fn scroll_to_top(&mut self)

pub fn scroll_to_bottom(&mut self)

✅ DIREKTES Scroll to bottom

pub fn update_content_height_silent(&mut self, new_content_height: usize)

✅ SILENT VERSION: Content-Höhe Update ohne Logging (Anti-Loop)

pub fn set_scroll_offset_direct_silent(&mut self, offset: usize)

✅ SILENT VERSION: Direkte Scroll-Offset-Kontrolle ohne Logging (Anti-Loop)

pub fn enable_auto_scroll_silent(&mut self)

✅ SILENT VERSION: Auto-Scroll aktivieren ohne Logging (Anti-Loop)

pub fn force_auto_scroll(&mut self)

✅ LEGACY-KOMPATIBILITÄT: Erzwingt Auto-scroll (nutzt jetzt Silent-Methoden)

pub fn page_up(&mut self)

✅ PAGE-SCROLLING Logik

pub fn page_down(&mut self)

pub fn set_scroll_offset_direct(&mut self, offset: usize)

✅ NEUE METHODE: Direkte Scroll-Offset-Kontrolle (bypass Event-System)

pub fn enable_auto_scroll(&mut self)

✅ NEUE METHODE: Auto-Scroll explizit aktivieren

pub fn disable_auto_scroll(&mut self)

✅ NEUE METHODE: Auto-Scroll explizit deaktivieren

pub fn get_visible_range(&self) -> (usize, usize)

Berechnet sichtbaren Bereich für Messages

pub fn output_area(&self) -> LayoutArea

Getter für Layout-Bereiche

pub fn input_area(&self) -> LayoutArea

pub fn window_height(&self) -> usize

pub fn content_height(&self) -> usize

pub fn scroll_offset(&self) -> usize

pub fn is_auto_scroll_enabled(&self) -> bool

pub fn terminal_size(&self) -> (u16, u16)

pub fn is_usable(&self) -> bool

Prüft ob Viewport groß genug ist

pub fn debug_info(&self) -> String

✅ ERWEITERTE Debug-Informationen

pub fn short_debug(&self) -> String

✅ KURZE Debug-Info für Logs (ohne das | Symbol)

impl Viewport

pub fn handle_event(&mut self, event: ViewportEvent) -> bool

✅ VERBESSERT: Event-Processing mit detailliertem Logging
