在OSX上开发后,我正在将我的一个Qt应用程序移植到Windows。我没有这个问题与OSX,但它发生在Windows 8下。当我打开并选择一个文件与 QFileDialog :: getOpenFileName()
,焦点切换到一些其他的应用程序和我不得不alt-tab回我的。
I'm porting one of my Qt apps to Windows after developing on OSX. I didn't have this problem with OSX, but it happens now under Windows 8. When I open and select a file with QFileDialog::getOpenFileName()
, the focus switches to some other app and I have to alt-tab back into mine. How do I make Qt revert to the main app once the file is selected in the dialog instead of doing this?
推荐答案
如果我们在对话框中选择了文件,只是忘记为 QFileDialog
设置 parent
- 您需要将指针传递到当前窗口 getOpenFileName :
You probably just forgot to set the parent
for the QFileDialog
- you need to pass the pointer to the current window to getOpenFileName:
QString fileName = QFileDialog::getOpenFileName(this, tr("Open File"),
"",
tr("Images (*.png *.xpm *.jpg)"));
