QFileDialog :: getOpenFileName不在Mac OS 10.8 Mountain Lion上设置初始目录 [英] QFileDialog::getOpenFileName doesn't set the initial directory on Mac OS 10.8 Mountain Lion

问题描述

我无法使用Qt 4.8的QFileDialog更改当前目录.在Windows和Mac OS 10.6 Snow Leopard上，相同的代码也可以正常工作.如果我不使用本地Mac OS X对话框，它也可以正常工作.

I can not change the current directory with QFileDialog with Qt 4.8. The same code works fine on Windows and Mac OS 10.6 Snow Leopard. It also works fine if I don't use the native Mac OS X dialog.

这有效:

fn=QFileDialog::getOpenFileName(this,"Select File","/Users/myuser/Desktop",QString(),0,QFileDialog::DontUseNativeDialog);

这不起作用:

fn=QFileDialog::getOpenFileName(this,"Select File","/Users/myuser/Desktop");

好像大多数情况下，它打开对getOpenFileName的最后一次调用的最后一条路径.

It looks like if most of the time it opens the last path of the last call to getOpenFileName.

推荐答案

这是Qt中的错误，据报道已在Qt 5.0.1和Qt 4.8.4中修复(尽管看来它仍可在4.8.4中重现)人(包括我自己).

This is a bug in Qt that is reportedly fixed in Qt 5.0.1 and Qt 4.8.4 (though it seems that it still reproducible in 4.8.4 by people (myself included)).

此错误在JIRA中已报告为 QTBUG-20771 ， QTBUG-28161 ，最后是 Gerrit 中的补丁链接.

This bug has been reported in JIRA as QTBUG-20771, QTBUG-28161 and finally QTBUG-35779 (which appears to have finally fully resolved the issue in Qt 5.2.1). Here is a link to the patch in Gerrit.
