QT：如何一次打开多个窗口（QWidgets）？

发布于 2024-09-28 21:38:49 字数 656 浏览 7 评论 0原文

我正在做 Web 界面测试程序，该程序应该同时在两个 webkit 窗口中打开两个 url。

我已经编写了测试自动化的代码。

1) 用户按下“Go”按钮，webkit (QWidget) 窗口打开

2) TestBot 类对象执行测试

3) 关闭

现在我的问题：单击“Go”按钮后，如何打开两个（或三个或更多）webkit (QWidget) 窗口，我的意思是，如何同时启动多个 TestBot，以便它们并行完成所有工作？

我明白，我需要查看多线程，我想到我需要将 QThread 继承到我的 TestBot 类定义中，作为“class TestBot : public QThread”，但是这是正确的解决方案吗？我做得对吗？接下来该怎么办？

我不能将代码编写为：

QThread process1;
QThread process2;
process1->start();
//some code here
process1->quit();

process2->start();
//some code here
process2->quit();

让一切并行工作吗？

我是Winapp世界的新手，我来自Web编程。希望得到您的帮助！

I'm doing web interface testing program which should open two urls in two webkit windows simultaneously.

I already did the code for the test automation.

1) User pushes 'Go' button and webkit (QWidget) window opens

2) TestBot class object performs tests

3) Closes

Now my question: After clicking on the button 'Go', how do I open two (or three or more) webkit (QWidget) windows, I mean, how do I launch several TestBots simultaneously so they do all the work parallel?

I understood, that I need to look at multithreads, I came up I need to inherit QThread into my TestBot class definition as 'class TestBot : public QThread', but is this right solution and do I do it right? What's to do next?

Can't I just write code as:

QThread process1;
QThread process2;
process1->start();
//some code here
process1->quit();

process2->start();
//some code here
process2->quit();

to make everything work parallel?

I'm a newbie in Winapp world, I came from Web programming. Hope for your help!

为了一次显示多个窗口，只需将它们排列起来并显示即可。

void ShowMultiple()
{
    QWidget *win1 = new QWidget();
    QWidget *win2 = new QWidget();
    QWidget *win3 = new QWidget();

    win1->show();
    win2->show();
    win3->show();
}

运行此代码后，应该会显示 3 个新的（空白）窗口。但是，如果您尝试执行一些需要很长时间才能显示窗口的代码，情况可能会发生变化。在这种情况下，您可能需要查看线程或 Qt::Concurrent 示例，请记住您真的、真的不能干扰任何其他线程中的 UI。

In order to show multiple windows at once, just line them up and show them.

void ShowMultiple()
{
    QWidget *win1 = new QWidget();
    QWidget *win2 = new QWidget();
    QWidget *win3 = new QWidget();

    win1->show();
    win2->show();
    win3->show();
}

After this code runs, there should be 3 new (blank) windows shown. However, if you are trying to execute some code that takes a long time along with showing the windows, things might change. In that case, you might want to look at the threads or Qt::Concurrent examples, bearing in mind that you really, really can't mess with the UI in any other thread.
