[SOLVED]QDialog problem, how i can keep the QDialog show until some case matches?
-
i write a dialog, which let the user enter a fileName, i want to keep the dialog show Until user enter a fileName which does Not exist.
i write like this in the func:
QDialog dlg(this);
dlg.exec();
if (dlg.result() == QDialog::Accepted)
{
...
while (QFile::exists(newFileName))
{
dlg.exec();
}
....
}
but i found it's wrong. what should i do this work?
thank you! -
I would not wait for the dialog to be closed. You should reimplement QDialog class and handle the OK button yourself: when a file exists, you should reject the result. If it does not, you can set the Accepted state.
-
yeh, i inherit from QDialog, and reimplement the accept.
but u know, it's easy and convient to do this Check in the window's slot, But not the custom QDilaog, because the relative path is in the window, and i don't want to pass these related param to the QDialog.
thank you -
Sorry, I don't understand your resoning. How is it possible for the dialog (where the user selects the path and file name) not to know the file name?
