@maxwell31 :
If the number of splits is fixed to one (i.e. 2 items), then you could define a property 'item' in each of your sub-views (equivalent to the 'contentItem' of e.g. ListView):

SplitView { id: splitView ... Rectangle { id: upperScreen color: "blue" property Item item: null Button { id: expandCollapseButton ... } } Rectangle { id: lowerScreen color: "red" property Item item: null } }

Then, in some JS assuming you have instances someItem1 and someItem2, you could parent/reparent those to those content items:

lowerScreen.item = someItem1 someItem1.parent = lowerScreen upperScreen.item = someItem2 someItem2.parent = upperScreen upperScreen.item.text = "ALL IS OK!" //assuming someItem2 has a text property

@AtoZ you may want to take a log at this blog post as it may help...

@Saman19
most likly by combining it with effectiveLayoutDirection, the entry one above flowcontrol in the docu

@mrjj Yes it helped, thanks.

@SGaist Ok that makes sense. Thank you

I registered it as RegiterType cause it is model derived from QAbstractListModel, enum is inside it. I would like to keep enum inside it rather than new header

Update:
I can do if(rolenamefortype === 0) etc, cause it's int based like C style enum. However I would like to do if(rolenamefortype === model.TYPEA) cause of clarity

@SGaist , thanks

My data are in such way organized that there are N rows that needs to be displayed, I could use gridview to display it the way i need but it's bad idea IMO, cause they will change during program execution and I would display it like

UPDATE:
I used QAbstractTableModel,

No idea how to delegate it so I get my row column structure.

I guess what I am looking for is custom View for my model?
What I got is NxN floats, lets say 3x3 float inside QAbstractTableModel and now looking for a way to put it into delegate, currently I can only display 1 row :/

@GrecKo oh thank you very much. I confused bottomMargin for anchors.bottomMargin. I wasn't aware of this property being available. This is exactly what I needed!

Thanks for sharing your findings !

Hi @YenZi
A little bit late, but could using a Loader and settings its asynchronous property to true work?
http://doc.qt.io/qt-5/qml-qtquick-loader.html#asynchronous-prop

I implemented it by using a Popup control with two states expanded and collapsed and changing the modal property so that when is collapsed it is not modal and when is expanded is modal. Also I added a transition animation.

The only thing I am missing is the "drag" feature...I am sure it can be done but is a bit more complex and probably I will not need this feature.

Hi everyone! I've solved this problem. In my case the problem was in asynchronous load images into another thread. When I changed asynchronous method to the synchronous all work fine.

Hi and welcome to devnet,

What version of Qt are you using ?
On what OS ?
Which architecture ?
What type of image is that ?

Hi there.

I think you can use TableViewColumn element to create a new column inside a TableView component.
If necessary, you can define your own delegate to set how the data is showed to user.

Also, to ensure that ModelTest work, I created rootContext as single model and opened qml page with this model to make ModelTest work. Resolving each seg fault resolved issue

Just by loading one page and coming back, we can't make out the memory leak. Try multiple times like this. If you see a increase & no decrease then we can conclude memory leak. If you can send me the complete example, we can try as well.

What is it that doesn't work? Any error messages?
Perhaps you might want to have a look at Thomas Boutroues qqmlobjectlistmodel.h.

@seyed As I understand things, you need to get hold of the item's transform and do whatever your rendering needs to do with it for it to have effect... see https://stackoverflow.com/questions/28535528/how-can-i-get-transform-matrix-for-qquickitem . (Similarly, nothing will implement the opacity property for you... you have to bring it into your OpenGL code and use it in your fragment shader.)

hi,

@maxwell31 said in Organizing the visible Elements, e.g. an Error Message:

e.g. accessing ErrorButton from WorkScreen which is a child of MainScreen or the other way round).

you can alias your WorkScreen in MainScreen to be alble to access it from outside :

// MainScreen.qml

Item{ property alias myWorkScreen : ws ... WorkScreen{ id: ws } }

// WorkScreen.qml

Item{ ... signal error() Button{onClicked:error()} }

Now in you main, you can create a function and connect it to your workScreen signal

ApplicationWindow { visible: true id: root objectName: "MainWindow" width: 800 height: 600 function workScreenErrorHandler(){ console.log("ws err") } Component.onCompleted:{ //connecting the signal mainScreen.myWorkScreen.error.connect(workScreenErrorHandler) } menuBar: MenuBar { } LeftBar{ } MainScreen{ id:mainScreen } ErrorScreen { visible: false } }

Hope this can help

There is no straightforward API for this. I see several possibilities:

custom painting in QQuickPaintedItem custom painting in QQuickItem custom painting via GL shaders custom painting in QML Canvas a set of 4 animated Rectangle components, simulating the line. An ugly solution, but probably the easiest to do

Perhaps BorderImage component can be forced to do an animation like that, but I doubt it.

@tansgumus said in javascript documentation:

Is there any plan to cover JavaScript docs by Qt?

Currently not.

As I mentioned, the Qt Project has no control over the JavaScript API, so it will not document the JavaScript API either. However, QML classes and methods are fully documented -- if you find something missing, please file a bug report.

@timday said in REST API client:

@tansgumus What counts as "very cheap hosting" these days? I've looked at those sort of environments before (typically things admined via "cpanel"?)

I pay 32$ per year with unlimited databases and bandwidth %99.9 Uptime. AWS' EC2 more expensive with less performance!

I solved it for now by using a size relative to its parent and calculating a scale from it. Also applying the same scale to the position of the Pathview gives a usable solution, but it requires a few additional calculations.
I see how the (617 * 411) resolution occurs.
So the Windows width: and height: properties are not sizes in pixels..

Desktop - 1920*1200 or 2560x1440
density 4.2969047380546925
pixelRatio 1

Mobile
density 6.5092731829573935 - 1620 x 1080
pixelRatio 2.626672502927989

1620/2.6266... gives 617
1080/2.6266... gives 411

@sierdzio Thanks for your input! The this-object was the parent widget holding the QQuickView. I solved it by saving the root object of the QQuickView:

QObject *obj = quickview->rootObject(); if (obj) obj->setProperty("ticks", tick_count); else qDebug() << "Could not set tick count!";

Anyway, I'll have a look at the different approach you suggest. It sound like a more robust way of interacting with QML.

Best regards, E
