如何设置目录分隔符以匹配操作系统? [英] How to set the directory separator character to match the operating system?

问题描述

我正在编写一个qt应用程序，目的是将其移植到3种主要操作系统上.

I am writing a qt application, with the goal of it being portable to the 3 major operating systems.

我正在使用QFileDialog选择一个文件夹，然后将其添加到QListWidget.但是，即使我在Windows上，文件夹名称也将作为E:/media返回.我希望它返回E:\ media

I am using QFileDialog to select a folder, and then adding it to a QListWidget. However the folder name is being returned as E:/media even though I am on Windows. I would want it to return E:\media

我可以使用一个简单的字符串替换，但是在Linux/Mac上，拥有\ home \ user \ Documents

I could use a simple string replace, but then on Linux/Mac it would look weird to have \home\user\Documents

我的代码(如果有帮助的话):

My code if it helps:

void LibrariesForm::on_addButton_clicked()
{
    QString dir = QFileDialog::getExistingDirectory(this, tr("Select Folder"), "/", QFileDialog::ShowDirsOnly);

    if (dir.isNull() == true)
    {
        return;
    }

    ui->librariesList->addItem(new QListWidgetItem(dir, ui->librariesList, 0));
}

我想您正在寻找 QDir :: toNativeSeparators().
