[英]How to accurately display string in JComboBox?
I have an array of strings that represent options in a drop-down menu. 我有一个字符串数组,表示下拉菜单中的选项。
String[] s_reflection_map = {
"x=W–1–x mod W ",
"x/W even x=x mod W; odd x=W–1–x mod W, no PI",
"same, but with Pixel Interpolation ",
"x=x mod W/2, y=y mod H/2 ",
"x>W–1,x=x mod W else x=W–1–x mod W ",
"x<W,x=x mod W//2 else x=W–1–x mod W ",
"x/W even,x=x mod W/2;odd x=W–1–x mod W/2 ",
"x/W even,x=x mod W/2;odd x=(W–1)/2–x mod W/2",
"simple "
};
JComboBox<String> jcb_reflection_map = new JComboBox<>(s_reflection_map);
Minus sign, the character "-" cannot be displayed correctly. 减号,字符“ - ”无法正确显示。
Can anyone remind me of why minus is illegal character? 任何人都可以提醒我为什么减去非法人物?
The subtraction symbols are encoded as literal Unicode EN DASH' (U+2013)
characters, the preferred glyph in a mathematical context. 减法符号被编码为文字Unicode
EN DASH' (U+2013)
字符,这是数学上下文中的首选字形。 In Java source, substitute the corresponding escape, for example, 在Java源代码中,替换相应的转义,例如,
"x=W\u20131\u2013x mod W ",
这种格式效果很好。
"x = W \u2013 x mod W"
