QML and Qt Quick

Okay, so now I know that I can ignore things like "Unqualified access" when it comes to something like this. But, now I'm facing a new problem: I cannot get the LEDs to do anything. I've tested them with a simple script to ensure they do work, and they do. So, there's something going on with my project's code somewhere that is causing them to not work correctly. I've included print statements which do show up, just not the lights. I think I'll be better off making a simple QML and Python setup to test a basic light animation and see what's going on.

@Mesrine I run the application directly from Qt Creator after building it. Moving set_source_files_properties did not help, the problem is the same. Bug report created https://bugreports.qt.io/browse/QTBUG-121758

@jarle said in Unable to get selection in TreeView to work in QML/QT6.6.1: I also found no way to get the QItemIndex for an element when it's rendered Did you try using the index property that is exposed to delegates or was that not suitable for what you needed? BTW, I haven't tried the new Qt 6 TreeView yet (I'm still on Qt 5 and the old, deprecated TreeView) but I will have to migrate soon so questions like yours are interesting to me.

To add a suffix in a SpinBox or a TextField I generally don't add it in the text directly but create a new Label as the child of the contentItem, and adjust the rightPadding accordingly. I think this could help you here, your actual text would then be digits only.

@GrecKo the problem is, that GridView releases it delegates when model's elements is removed. It provokes Image to reload if delegate is shown again. No meter if I set cache: true Such a shame that GridView don't have reuseItems like ListView I've come with next decision. I've created Repeater containing Image that use source model. GridView's delegate Image use Repeater's function itemAt() giving delegate's index after mapping to source model: //Image in deleagte Image { Component.onCompleted: { source = appModelImages.loadImage(appFilterModel.mapRowToSource(parent.delegateIndex)) // custom implementation } ... } //Repeater Repeater { id: appModelImages visible: false function loadImage(index){ return itemAt(index).source } model: AppModel delegate: Image { visible: false asynchronous: true source: model.boxart } } This may be not the best decision, but "faster" than create own delegate pool for GridView. Didn't see any examples of implementing mechanism like this. Repeater should work fine, as it relays on source model. And as I expected, images live when source model does.

@GrecKo agreed that that is a cleaner way to do it, but it doesn't help the OP understand where they went wrong with anchors.

@jgerber All i want to say is.: Thank you. Your solution worked perfectly, and for the love of god i couldn't find other correct solution online.

Since I'm not allowed to attach files here, I've uploaded it to Google. Hope that works: https://drive.google.com/file/d/1zcEmt09gpg8CxYdbvb1oW_P3tbc1LHxF/view?usp=drive_link

@nixako2186 Since your code runs, this means you can override it. However, you may lose control over when your local enabled or the one defined in Button is used. Therefore, better never do it.

Hi and welcome to devnet, If memory serves well, you should have a file dialog that is shown as a drawer which is an integral part of the application window. That's usual on macOS for modal dialogs.

@JoeCFD No. I guess I should've specifically mentioned that I also looked into the Button group documentation (although I did originally talk about how AbstractButton and Exclusive, which are part of the Button group, will not work for me). Also, trying to make them as buttons completely screws up my entire layout for everything and I can never find helpful answers as to why, but that's a different subject for another time. All I want to know is if it is possible with my current setup. If yes, how do I go about it? If no, why? . . . UPDATE: I found out that it is indeed possible, and it was incredibly simple! All I had to do was include some additional onClicked handlers to set the states of the other buttons to off. Before: MouseArea { anchors.fill: parent onClicked: leftSignal.buttonState = (leftSignal.buttonState === 'on') ? 'off' : 'on'; } After: MouseArea { anchors.fill: parent onClicked: { rightSignal.buttonState = 'off'; brakeLights.buttonState = 'off'; parkingLights.buttonState = 'off'; leftSignal.buttonState = (leftSignal.buttonState === 'on') ? 'off' : 'on'; } }

@afalsa same here

Okay, after reading through the source code for qquickmessagedialog.cpp, I saw a use-case for supporting different buttons. I added the following: onButtonClicked: function (button, role) { switch (button) { case MessageDialog.Ok: exportDialog.close() break; } } Apparently, without this and explicitly telling the dialog to close, you can't reopen the message dialog. Seems goofy to me.

@JoeCFD Thank you
