[英]How can I wait for a QWidget to close using QTestLib? [Qt5]
I am writing a QTest
based test case for a class that derives from QWidget
. 我正在为从
QWidget
派生的类编写基于QTest
的测试用例。
After showing the widget, I want the test to end as soon as the widget is closed . 显示小部件后,我希望测试在小部件关闭后立即结束 。
My first attempt was to use QSignalSpy
, only to find out that QWidget
really does not send out a signal on close()
. 我的第一次尝试是使用
QSignalSpy
,只是发现QWidget
确实没有在close()
上发出信号。
So what is the "right way" to do this using QTest
primitives? 那么,使用
QTest
原语执行此操作的“正确方法”是什么?
What if you specify Qt::WA_DeleteOnClose attribute for the widget and wait on its destroyed() signal? 如果为窗口小部件指定 Qt :: WA_DeleteOnClose属性并等待其destroy ()信号怎么办?
pMyTestWidget->setAttribute(Qt::WA_DeleteOnClose);
pMyTestWidget->show();
// test thread...
QSignalSpy watchDog(pMyTestWidget, SIGNAL(destroyed(QObject*)));
watchDog.wait();
