c++ - Qt:如何制作可点击路径以在点击时运行视频文件

Question

我是 Qt 的新手，我正在开发一个搜索应用程序，它可以搜索并列出文件夹中的所有视频。我想生成可点击的文件路径，在点击时可以运行视频文件。这是我正在尝试执行的代码:

void MainWindow::on_pushButton_7_clicked()
{
QString key = ui->key->toPlainText();     //get the search keyword
QString text = ui->DIR->toPlainText();    //get the directory

string cmd = "./search_by_keyword.sh "+text.toStdString()+" "+key.toStdString();                          
                                          //command to run a shell script with 2 arguments
system("chmod +x search_by_keyword.sh");
system(cmd.c_str());                      //run the script which produce a txt file containing the search results

ifstream fin { "search_result.txt" };     //read result and print out
string s;
QStringList all;

while(!fin.eof()){
getline(fin,s);
string convert = s;                       //I want each "s" produced to be clickable, and it run the video in the path when clicked
QString str = convert.c_str();
all << str;
}

fin.close();
ui->searchResult->setText(all.join("\n")); //searchResult is currently a textBrowser

}

以下是用户界面的截图，以防万一:

谢谢!
