QTQuick(QML)中的FileDialog:以给定名称保存文件 [英] FileDialog in QTQuick (QML): Save file under given name

问题描述

我们正在构建Qt Quick应用程序，该应用程序必须能够以给定名称保存文件.

We're building a Qt Quick app, that must be able to save a file under a given name.

在 FileDialog 组件中您只能设置一个目录.这不是非常用户友好，因为您不想在每次下载文件时都手动输入文件名.

In the FileDialog component you can only set a directory. This is not very user-friendly, since you don't want to type in a filename by hand every time you download a file.

到目前为止，我们尝试了不同的事情

So far we tried different things

QtQuick.Dialogs中的

1. FileDialog:无法设置文件名

1. FileDialog from QtQuick.Dialogs: filename cannot be set

通过QPlatformFileDialogHelper进行的本机对话框(调皮的私人c ++ hack):无法在Linux(Gnome)上设置文件名

Native dialog via QPlatformFileDialogHelper (naughty private c++ hack): filename cannot be set on Linux (Gnome)

通过静态QFileDialog :: getSaveFileName()进行的本地对话框:在快速应用程序中，没有用于父级"的QWidget.

Native dialog via static QFileDialog::getSaveFileName(): in Quick application there is no QWidget available for 'parent'

QT对话框:模态无效，因为未设置'parent'.在快速应用程序中，没有QWidget可用于setParent()调用

QT dialog via QFileDialog instance: Modality doeas not work, since 'parent' is not set. In Quick application there is no QWidget available for setParent() call

(将C ++与QT 5.1和QtQuick 2.1一起使用，包括所有桌面组件)

(Using C++ with QT 5.1 and QtQuick 2.1 incl. all desktop components)
