QML and Qt Quick

I know it's been a few years, but this might still be helpful to someone :) For me, this approach works: delegate: MyDelegate { MouseArea { id: _mouseArea anchors.fill: parent } Binding { when: _mouseArea.pressed target: _listView property: "interactive" value: false } } With this setup, you should be able to scroll the list view using the scroll wheel. When you perform a press-and-drag gesture, it will disable the scrolling or flicking behavior. Once you release the mouse button, the binding will be restored, making the list view interactive again, so you can scroll with the mouse wheel once more. Even when you have multiple elements (i.e., instantiated delegates), dragging across them won't reset the interactive property until you release the mouse button.

@Markkyboy The whole problem with OpacityMask was QtGraphicalEffects since it is not included in Qt6 but I in a forum I found import Qt5Compat.GraphicalEffects and it now works like following: Rectangle { id: mask anchors.left: parent.left anchors.leftMargin: 15 width: 50 height: 50 radius: 25 clip: true } Image { id: storeIcon anchors.fill: mask source: "qrc:/image.png" fillMode: Image.PreserveAspectCrop layer.enabled: true layer.effect: OpacityMask { maskSource: mask } }

Don't use anchors for the dot, use a fixed value, something like Image { id: dot width: someWidth height: someHeight x: someXPositionRelativeToXBodyImage y: someYPositionRelativeToYBodyImage ..... }

Good to know. I'm running 6.5.3 on Windows 11. Thanks for pointing me in the right direction, though.

@GrecKo Thanks for your reply!

@charlie2024 If you are moving forward with the existing method, no problem. However, for your information, Opacity Mask on Qt6 is now possible from Qt 6.2 onwards using the "Qt5Compat.GraphicalEffect" library. This library contains many graphical effects initially discontinued and later added due to high demand from developers like DropShadow, Gaussian Blur, etc. Here is the link below Qt5Compat GraphicalEffect Happy coding and happy learning :)

It is not giving the option to select the directory. "Save" button will not be enabled unless there some text exist in the "Save As:". As a work-around type the FolderName you want in the "Save As". Save button will be enable. Now if you click on the save button, directory you entered will be set to selectedFile property. console.log(" File Selected.......folder.."+fileDialogOutput.selectedFile) According to the documentation, there is no mention of directory selection. However 5.15.x FileDialog does mention the directory selection. I see FileDialog disparity between Qt 5.15.x to 6.x. I will file a enhancement bug for this.

@Mewo Also move the ticket solved

Hello everybody, I'm overlucky: I found the error for myself (-: The correct code line is now: emit dataChanged(index(0),index(nparticles-1)); instead of emit dataChanged(index(0),index(nparticles)); Now I can start working! Thanks to all! Tobias

SOLVED thanks to a previous forum post regarding using MultiEffect on Image{} type component All that's required is to set VectorImage's visible to false, since the compositor seems to be double rendering, I suppose, creating the unwanted outline of the SVG Thanks to 6.5 article: https://forum.qt.io/topic/144070/qt6-color-svg-using-multieffect/3 and member: https://forum.qt.io/user/mzimmers New graphics: [image: 3914746d-1cc6-44c3-9a9c-23789cae360a.png] WORKING CODE: Item { id: root color: <input from higher level> source: <input from higher> VectorImage { id: mySVG ~~~~ same lines from above ~~~~~ visible: false <======== DONT FORGET THIS } MultiEffect { id: colorOverlay source: mySVG anchors.fill: mySVG colorization: 1.0 // opacity equivalent colorizationColor: root.color } }

@SimpleY i ve got same problem as your, try to go to preferences->Qt Quick->QML/JS editing-> QML Language server and remove tick on Tun on (leave all unchecked) it worked for me.

QScrollArea has a method ensureWidgetVisible() which seems to be missing from Flickable. StackOverflow had a discussion on this: https://stackoverflow.com/questions/45946637/how-to-make-flickable-ensure-the-visibility-of-an-item-inside-of-it. (I'm not a user of QML, but this might provide a different way of tackling the problem.)

@johngod This is a great reference. I will check the code and compare what I am doing wrrong here. Thank you so much.

It isn't that TextArea isn't able to "handle" Images; you can indeed place images within a TextArea and control their location. The problem is, your image is embedded in the text property of the TextArea. I've never seen this done before, but I think you'd have to use HTML/CSS constructs within the <img> in order to do anything (and I'm not sure this will work).

Turns out it wasn't me doing something wrong. It was a Qt bug: https://bugreports.qt.io/browse/QTCREATORBUG-31949

@GrecKo Thank you very much! You really help me solve this problem!
