在Qt中打开Hyperlink中的文本文件

Question

我正在尝试在超链接的单独窗口中打开文本文件。这就是我所拥有的：

#include "aboutdialog.h"
#include "ui_aboutdialog.h"

aboutdialog::aboutdialog(QWidget *parent) :
QDialog(parent),
ui(new Ui::aboutdialog)
 {
   ui->setupUi(this);
   this->setFixedSize(550,380);
 }

 aboutdialog::~aboutdialog()
 {
 delete ui;
 }

 void aboutdialog::on_pushButton_clicked()
 {
 close();
 }


 // Open Qt Libraries Terms and Conditions
 void aboutdialog::on_label_6_linkActivated(const QString &link)
 {

 QString fileName = QFileDialog::getOpenFileName(
           this,
           tr("Qt libraries Terms and Conditions"),
           "",
           tr("Text Files (/LICENSE.LGPL)"));
 if(!fileName.isEmpty())
  {
   QFile file(fileName);
   if(file.open(QIODevice::ReadOnly | QIODevice::Text))
   {
       file.readAll();
    }
  }
}

它告诉我：

ShellExecute 'LICENSE.LGPL' failed (error 2)

有人可以指出问题吗？

Answer 1

您的UI文件很可能包含带有链接的QLabel，并且此QLabel将openExternalLinks属性设置为true。

Answer 2

也许

QString fileName = QFileDialog::getOpenFileName(
                                this,
                                tr("Qt libraries Terms and Conditions"),
                                "/LICENSE.lgpl",
                                tr("LICENSE (*.lgpl);;All Files (*)")
                                );
