QT学习笔记之十四 StringMatch

用于正则表达式，通配符，完整匹配三种方式

 

============================================================

stringmatch.h

#ifndef STRINGMATCH_H#define STRINGMATCH_H#include <QtGui/QDialog>class QComboBox;class QLabel;class QLineEdit;class QListView;class QSortFilterProxyModel;class QStringListModel;namespace Ui{ class StringMatch;}class StringMatch : public QDialog{ Q_OBJECTpublic: StringMatch(QWidget *parent = 0); ~StringMatch();private slots: void reapplyFilter();private: Ui::StringMatch *ui; QStringListModel *sourceModel; QSortFilterProxyModel *proxyModel; QListView *listView; QLabel *filterLabel; QLabel *syntaxLabel; QLineEdit *filterLineEdit; QComboBox *syntaxComboBox;};#endif // STRINGMATCH_H

stringmatch.cpp

#include <QtGui>#include "stringmatch.h"#include "ui_stringmatch.h"StringMatch::StringMatch(QWidget *parent) : QDialog(parent), ui(new Ui::StringMatch){ ui->setupUi(this); QTextCodec::setCodecForCStrings(QTextCodec::codecForLocale()); QTextCodec::setCodecForTr(QTextCodec::codecForName("utf8")); //sourceModel sourceModel = new QStringListModel(this); sourceModel->setStringList(QColor::colorNames()); //proxyModel proxyModel = new QSortFilterProxyModel(this); proxyModel->setSourceModel(sourceModel); proxyModel->setFilterKeyColumn(0); //listView listView = new QListView; listView->setModel(proxyModel); listView->setEditTriggers(QAbstractItemView::NoEditTriggers); //filter filterLabel = new QLabel(tr("要匹配的字符串")); filterLineEdit = new QLineEdit; filterLabel->setBuddy(filterLineEdit); //syntax syntaxLabel = new QLabel("匹配方式选择"); syntaxComboBox = new QComboBox; syntaxComboBox->addItem("正则表达式",QRegExp::RegExp); //A rich Perl-like pattern matching syntax. This is the default. syntaxComboBox->addItem("通配符",QRegExp::Wildcard); //This provides a simple pattern matching syntax similar to that used by shells (command interpreters) for "file globbing". syntaxComboBox->addItem("完全匹配",QRegExp::FixedString); //This is equivalent to using the RegExp pattern on a string in which all metacharacters are escaped using //当filterLineEdit和syntaxComboBox connect(filterLineEdit,SIGNAL(textChanged(const QString &)),this,SLOT(reapplyFilter())); connect(syntaxComboBox,SIGNAL(currentIndexChanged(int)),this,SLOT(reapplyFilter())); //布局 QGridLayout *layout = new QGridLayout; layout->addWidget(listView,0,0,1,2); layout->addWidget(filterLabel,1,0); layout->addWidget(filterLineEdit,1,1); layout->addWidget(syntaxLabel,2,0); layout->addWidget(syntaxComboBox,2,1); setLayout(layout); setWindowTitle(tr("String Matching"));}StringMatch::~StringMatch(){ delete ui;}void StringMatch::reapplyFilter(){ QRegExp::PatternSyntax syntax = QRegExp::PatternSyntax(syntaxComboBox->itemData( syntaxComboBox->currentIndex()).toInt()); QRegExp regExp(filterLineEdit->text(),Qt::CaseInsensitive,syntax); proxyModel->setFilterRegExp(regExp);}

直到今天才把Qt4的中文乱码搞定太尴尬了.......鄙视下自己.....

只要程序中加入

QTextCodec::setCodecForCStrings(QTextCodec::codecForLocale()); QTextCodec::setCodecForTr(QTextCodec::codecForName("utf8"));

当然要看情况来说，你的环境可能是GBK或者其他的...
