Expand description

螢幕佈局資訊

管理編輯器視窗的尺寸和滾動位置。

§範例

use wedi_widget::ScreenLayout;

let mut layout = ScreenLayout::new(24, 80);
layout.scroll_to(10, 0); // 滾動到第 10 行
layout.resize(30, 100);  // 調整尺寸

Fields§

§offset_row: usize

視窗頂部顯示的邏輯行號

§offset_col: usize

水平偏移(單行模式使用)

§screen_rows: usize

螢幕行數

§screen_cols: usize

螢幕列數
