快速QT4.5.3——QFileDialog

#include <QtGui/QApplication>

#include <QtCore/QTextCodec>

#include <QFileDialog>

#include <QString>

int main(int argc, char *argv[])

{

    QApplication app(argc, argv);

    QTextCodec::setCodecForTr(QTextCodec::codecForName("gb18030"));

       QString path = QFileDialog::getOpenFileName(NULL, QObject::tr("打开"), ".", QObject::tr("文件类型(*.jpg *.png)"));

    QString path = QFileDialog::getSaveFileName(NULL, QObject::tr("保存"), ".", QObject::tr("文件类型(*.jpg *.png)"));

    return app.exec();

}

提供的是WindowsLinux平台上的本地对话框

 

#include <QtGui/QApplication>

#include <QtCore/QTextCodec>

#include <QFileDialog>

#include <QString>

int main(int argc, char *argv[])

{

    QApplication app(argc, argv);

    QTextCodec::setCodecForTr(QTextCodec::codecForName("gb18030"));

    QFileDialog fileDialog;

    fileDialog.setWindowTitle(QObject::tr("打开"));

    fileDialog.setDirectory(".");

    fileDialog.setFilter(QObject::tr("文件类型(*.exe *.chm)"));

    fileDialog.open();

    QString path = fileDialog.selectedFiles()[0];

    return app.exec();

}

提供的始终是Qt自己绘制的对话框
