[英]Qt program freezes every time
I'm making a C++ GUI program in Qt using qtcreator its not complete yet but when ever I build and run to test the program it runs then if i click buttons that open a file or write something in a file, the button does that and then the program freezes. 我正在使用qtcreator在Qt中制作一个C ++ GUI程序,但尚未完成,但是每当我构建并运行以测试该程序是否运行时,如果我单击打开文件或在文件中写入内容的按钮,该按钮就会执行此操作,并且然后程序冻结。 Why this happens, What I'm doing wrong or what's the issue.
为什么会发生这种情况,我做错了什么或出了什么问题。
It mainly freezes in theses two functions: 它主要冻结在这两个功能中:
void MainWindow::on_kmpOpenButton_clicked()
{
QString kmplayerloc = "\"F:\\Program Files\\The KMPlayer\\KMPlayer.exe\"";
QProcess::execute(kmplayerloc);
}
void MainWindow::on_nbopenbutton_clicked()
{
// Remember tha if you have to insert " in a string \"....location of file or anything u want to put.......\"
QString netbeansloc = "\"F:\\Program Files\\NetBeans 7.4\\bin\\netbeans.exe\"";
QProcess::execute(netbeansloc);
}
From the documentation 从文档中
Starts the program program [..] in a new process, waits for it to finish , and then returns the exit code of the process.
在新进程中启动程序程序 [..], 等待它完成 ,然后返回该进程的退出代码。
The calling thread freezes until the external process is finished. 调用线程冻结,直到外部进程完成。 If you don't want this, use the method
start
or startDetached
. 如果您不想这样做,请使用
start
或startDetached
方法。
