Dialogs in Qt 6 using CMake

qcoderpro

Hi,

Went for this page and read it until end, then created the following example just to make sure it works:

The dialog is not shown! There's either no errors! What is the problem, please?

Qt 6.2.2, CMake

@qcoderpro
you must call open() on the dialog at some point. its not visible by default.

(Dialog inherits Popup)

Or simply, visible: true.
Thank you for your brief and to the point reply.

Now if I want to add a simple FileDialog like this:

FileDialog {
       id: fileDialog
       folder: StandardPaths.writableLocation(StandardPaths.DocumentsLocation)
   }

The compiler gives me the error: FileDialog is not a type
So I need import Qt.labs.platform. When I add that, this time I get an error about the Dialog!
Dialog is an abstract base class

Seemingly there can't be possible to have both the Dialog and FileDialog elements together in a project!

Dialog in FileDialog is in QtQuick.Dialogs import though: https://doc.qt.io/qt-6/qml-qtquick-dialogs-filedialog.html . Can you try this?

Apparently Qt6's elements are just being updated. Look the first example in that link where there's a folder property. Do you see it in on the list declared as FileDialog properties!? The Qt Creator's compiler also rises an error regarding that.

The 2 imports are clashing because they both contain a Dialog type. Use an "import as" to prevent this:

import QtQuick
import QtQuick.Controls
import Qt.labs.platform as Labs

Window {
   // ...
   Dialog {
       // ...
    }
    Labs.FileDialog {
        // ...
    }
}

I'm glad to know that how you found this.

Still the compiler has an issue with the folder line!
ReferenceError: StandardPaths is not defined

Dialog {
       id: dialog
       x: 200
       title: "test"
       visible: true
       standardButtons: Dialog.Ok | Dialog.Cancel
   }

   Labs.FileDialog {
       id: fileDialog
       folder: StandardPaths.writableLocation(StandardPaths.DocumentsLocation)
   }

I read https://doc.qt.io/qt-6/qmlreference.html

Still the problem with a property of FileDialog to bring the explorer window to select the file exits: Cannot assign to non-existent property "folder". I also tried currentfolder but the same error message!
