設(shè)計(jì)需求基本設(shè)計(jì)要求：日記本使用Java語(yǔ)言開(kāi)發(fā)設(shè)計(jì)。課程的基本功能包括萬(wàn)年歷、記事本和輔助功能三個(gè)部分。萬(wàn)年歷部分由微調(diào)器確定年月，由一組文本框顯示日歷。年月可選擇數(shù)據(jù)符合邏輯，默認(rèn)為當(dāng)前日期。月歷顯示應(yīng)該符合查看習(xí)慣，如星期六和星期日分別用不同顏色表示，當(dāng)日可用特別的字號(hào)和顏色及時(shí)本區(qū)，記事本內(nèi)容按年月日記錄且保存。微調(diào)器應(yīng)該進(jìn)行事件設(shè)置，以及即時(shí)地顯示該年月的月歷；日期文本框可監(jiān)聽(tīng)鼠標(biāo)事件，當(dāng)單擊任何一個(gè)日期時(shí)，若該日有記事內(nèi)容，則在日記本中顯示該日期的記錄文字；若該日無(wú)記錄，記事區(qū)保持空白。日記本應(yīng)該是開(kāi)放的，內(nèi)容可按日期增減，保存應(yīng)即時(shí)，刪除需謹(jǐn)慎刪除記錄時(shí)，應(yīng)進(jìn)行對(duì)話框詢問(wèn)確定。輔助功能包含了日記的導(dǎo)入導(dǎo)出?！皩?dǎo)入”可以將其他日記文件導(dǎo)入合并到當(dāng)前“寫字留痕”的日記本中；“導(dǎo)出”可將“寫字留痕”的所有記錄內(nèi)容按日期為序?qū)С龅揭粋€(gè)文本文件中。系統(tǒng)界面外觀和布局，可個(gè)性化設(shè)計(jì)，總體原則是“界面簡(jiǎn)潔，操作便捷”。
