Qt5开发及实例-CH802.rar,Qt5实现将数值代码转换为文字的模型的代码

#include "modelex.h" ModelEx::ModelEx(QObject *parent):QAbstractTableModel(parent) { armyMap[1]=tr("空军"); armyMap[2]=tr("海军"); armyMap[3]=tr("陆军"); armyMap[4]=tr("海军陆战队"); weaponTypeMap[1]=tr("轰炸机"); weaponTypeMap[2]=tr("战斗机"); weaponTypeMap[3]=tr("航空母舰"); weaponTypeMap[4]=tr("驱逐舰"); weaponTypeMap[5]=tr("直升机"); weaponTypeMap[6]=tr("坦克"); weaponTypeMap[7]=tr("两栖攻击舰"); weaponTypeMap[8]=tr("两栖战车"); populateModel(); } void ModelEx::populateModel() { header<<tr("军种")<<tr("种类")<<tr("武器"); army<<1<<2<<3<<4<<2<<4<<3<<1; weaponType<<1<<3<<5<<7<<4<<8<<6<<2; weapon<<tr("B-2")<<tr("尼米兹级")<<tr("阿帕奇")<<tr("黄蜂级") <<tr("阿利伯克级")<<tr("AAAV")<<tr("M1A1")<<tr("F-22"); } int ModelEx::columnCount(const QModelIndex &parent) const { return 3; } int ModelEx::rowCount(const QModelIndex &parent) const { return army.size(); } QVariant ModelEx::data(const QModelIndex &index, int role) const { if(!index.isValid()) return QVariant(); if(role==Qt::DisplayRole) //(a) { switch(index.column()) { case 0: return armyMap[army[index.row()]]; break; case 1: return weaponTypeMap[weaponType[index.row()]]; break; case 2: return weapon[index.row()]; default: return QVariant(); } } return QVariant(); } QVariant ModelEx::headerData(int section, Qt::Orientation orientation, int role) const { if(role==Qt::DisplayRole&&orientation==Qt::Horizontal) return header[section]; return QAbstractTableModel::headerData(section,orientation,role); }
