QT中，保存文件弹出的对话框文件名一栏能读取lineEdit的文本信息 怎么实现

[清风在侧]

QT求助 ，想实现弹出的保存文件对话框文件名那里能读取新建项目名的名称，可是怎么搞都不行，我用的是QFileDialog::getSaveFileName，请问大神该怎么实现

[dext]

QString fileName = QFileDialog::getSaveFileName(this, tr("Save File"),
"/home/jana/untitled.png",
tr("Images (*.png *.xpm *.jpg)"));

The file dialog's working directory will be set to dir. If dir includes a file name, the file will be selected. Only files that match the filter are shown. The filter selected is set to selectedFilter. The parameters dir, selectedFilter, and filter may be empty strings. Multiple filters are separated with ';;'. For instance:

那还是不要用静态方法。因为静态方法内部是这么实现的：

    QFileDialog dialog(args);
    dialog.setSupportedSchemes(supportedSchemes);
    dialog.setAcceptMode(AcceptSave);
    if (selectedFilter && !selectedFilter->isEmpty())
        dialog.selectNameFilter(*selectedFilter);
    if (dialog.exec() == QDialog::Accepted) {
        if (selectedFilter)
            *selectedFilter = dialog.selectedNameFilter();
        return dialog.selectedUrls().value(0);
    }
    return QUrl();
