Qt -2:通過程式設計完成一個測試介面
阿新 • • 發佈：2018-12-10
一 目的：
這幾天在學習QT，打算通過程式設計的方式完成如下測試介面。由於才開始寫，程式碼還不夠簡潔，過於冗餘。但先實現功能吧，後續再改善。
二 我寫的介面如下，暫時還有些差距，不過這都是暫時的。
三 流程：
1 檔案 --> 新建檔案或專案-->（專案-->應用程式）Qt Gui應用-->選擇-->下一步-->下一步-->（基類選擇)QWidget，並取消建立介面後面的√-->下一步-->完成
2 程式設計思想：
其實用程式碼來寫介面不難，只是你需要清楚其間的規則。比如，我在寫這個介面的時候就是按如下的佈局來寫的。在寫左上角的按鈕組時，嘗試了很多方法：比如建立一個Splitter的主介面，然後將主介面左邊放置GridLayout屬性或QHBoxLayout
或QVBoxLayout的Layout,都不行。最後才發現可以將左邊介面設定為Splitter屬性，這樣就沒問題了。
3 具體程式碼：其他檔案不用改，只需要main.cpp中寫如下程式碼：
main.cpp: #include "widget.h" #include <QApplication> #include <QLayout> #include <QLabel> #include <QSplitter> #include <QGridLayout> #include <QComboBox> #include <QPushButton> #include <QListWidget> #include <QTableWidget> #include <QGroupBox> #include <QDebug> #include <QStackedWidget> #include <QButtonGroup> #include <QTextBrowser> #include <QStringList> #include <QHeaderView> int main(int argc, char *argv[]) { QApplication a(argc, argv);

四 遺留問題：
1 無法顯示中文？
嘗試了很多方法都不行
2 如何在表格中插入圖片？
3 PushBotton的連線及函式如何寫？
4如何實現翻頁的效果？
