最新选择的目录作为QFileDialog中的默认目录

Question

如何在QFileDialog中将最新选择的目录设置为默认目录？

Answer 1

You should store last selected directory in some variable and use it during next call of QFileDialog:: getOpenFileName :

QString path = "/";
QString fileName = QFileDialog::getOpenFileName(this, "Open file", path);
path = QFileInfo(fileName).path();

// default directory will be directory from previous call
QString anotherFilename = QFileDialog::getOpenFileName(this, "Open file", path);
