It does look like a similar issue. I was able to find a workaround thanks to this bug report. Setting the target OSX version to 10.12 in CMake did the trick.

@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!

@Angelking 恰好我也在做这方面的研究。
我的需求是，为我们的动作编辑器增添Direct3D的支持，因为用户更加习惯MME----这是一个基于HLSL的渲染框架。
这里问题在于我们使用的是Qt Quick，而现有的代码是和OpenGL深度绑定的，我们需要做的是考察哪些地方和OpenGL深度绑定的，然后尝试抽象出来，做好做成一个插件，我是考察Qt插件的写法决定将OpenGL相关的内容放在插件里实现。

想让Qt Quick应用和OpenGL和Direct3D解耦，我想一个方法就是使用RTT技术。就是采用不同的渲染器在一个纹理图上渲染，这样有可能通用。但是其中的难点感觉还是挺多的，现在在艰难地攻克。

After some tinkering, I've gotten the designer plugin to work the way I originally wanted. I simply commented out the 'module' directive in the 'qmldir' file:

# module MyLib typeinfo plugin.qmltypes plugin MyLib ../ designersupported

and added some qmake targets to automatically run 'qmlplugindump' post-build.

So now my plugin directory structure looks like this:

/imports |---MyLib.dll (or libMyLib.so) |---/MyLib |---|---qmldir |---|---plugin.qmltypes

Now I can get the plugin to run in 'qmlscene':

qmlscene -I <imports directory> <main qml file>

There are only two caveats in this case. First, QML files that are to import anything from the library must first import 'MyLib 1.0' before importing anything else ('MyLib.Rectangle', 'MyLib.Circle', etc.). This is so that the plugin is loaded initially to populate the other imports. Secondly, this will produce the following message when the plugin is loaded:

Module 'MyLib' does not contain a module identifier directive - it cannot be protected from external registrations.

However in my case, this is not an issue and can be safely overlooked.

@dv__ said in QML animations with dynamic content:

Also, just out of curiosity, in a more generic case (say, some arbitrary, non-grid arrangement), would my approach make sense? I suppose I could still use ListModel in this case, but the arrangement would have to be done manually, not with an existing view.

To do this I'd use a raw Item container with a Repeater and manual positioning in the delegates.

@GrecKo thanks for your comment. I've managed to create the window in which people would touch the video, but I'm not sure how to make the player. I've seen there is a library, Qt media, but I don't really know how to bind it with the other screen.

You have to enable Use QML emulation layer that is built with the selected Qt in the settings, since Qt Creator does ship with Canvas3D.
Note that Canvas3D is not officially supported in the designer, though.

Thanks @jpnurmi,

This is exactly what i was looking for, all my issues are solved.

Hi and welcome to devnet,

Why not free anymore ? Looks rather like a licensing issue. LGPLv2.1 has been replaced by LGPLv3.

Hi,

code.qt.io is the central repository of all Qt's code.

Start from the qtbase module to have the basic pieces. If you would like to learn the internal, helping fixing bugs will also give you a better understanding of how things are working.

@p3c0 said:

@Kofr So is it that you want to access the roles (namely hue, saturation, brightness) values from outside of this ListView delegate ? If so then did you accessing ListVIew model from outside ? Once you get hold of it the data can be accessed too.

code above is just example, not my case. what I need is to get model.roleName of delegate j when I work in delegate i

@Wieland
Thank you for testing :)
I've done a bugreport: https://bugreports.qt.io/browse/QTBUG-53046

Hi,

Since those are the same patches you should only target one branch. If it's the wrong one, don't worry it will be changed for you.

In order to get them move forward, you should add reviewers that are concerned by your patches e.g. the module maintainers.

One probable remark you will have is that your patch modifies several unrelated stuff so you should split them in order to ensure atomic changes e.g. one disables the item view part, another one the shortcut etc.

Hi, I finally got the latest 5.6.0 baseline compiled for iOS and can confirm that 5.6.0 does not show this tableview error.

Thanks for your help, well appreciated !!

Hi and welcome to devnet,

I'd recommend posting this question to the interest mailing list. You'll find there Qt's developers/maintainers (this forum is more user oriented)

That one's a classic (and a question that regularly comes back)

Hi,

There's a conversion done when you set the color property thus currently what you are doing is comparing a color with a string.

The solution is: background.color = Qt.colorEqual(background.color, "steelblue") ? "purple" : "steel blue"

@jimmy274 You're Welcome :)
A more interesting way but through C++ would be to use QQuickPaintedItem to create your own custom item. You can re-implement paint method to draw your custom shapes, text etc.. It uses QPainter to achieve this. Try looking for setCompositionMode and setClipRegion methods. An example for QQuickPaintedItem is here.

@JKSH Thanks for your help, May you help me more by writing a sample code for this ?

Thanks

yes my creator is 3.2.1
but i like understand how a qml file run with plugins!?

@mcosta Thanks for the reply. If I will not find any other ways I'll use different files.

Now it's distributed as package of MSYS2 project.

Now it's distributed as package of MSYS2 project.
Type in the appropriate shell:

pacman -S mingw-w64-i686-osgQtQuick

or

pacman -S mingw-w64-x86_64-osgQtQuick

To run test game script:

wget https://github.com/podsvirov/osgqtquick/raw/develop/tests/sokoban.qml qmlscene sokoban.qml

@p3c0
The cosmetic pen issue won't be easy to solve though.

Hi @Pheelbert,
Make use of QQuickWindow::beforeRendering signal to draw the OpenGL stuff beneath QML scene.
Have a look at this flow for more info, especially Pt. no. 8 and the example suggested by @SGaist.

@antemort You can put the 2 gauge images besides eachother inside a RowLayout and add it to the Image element which contains that background image. Advantage of layouts is that it automatically positions the items inside it when it resizes.

My app has even doubled its size after being approved by Apple! When it was in Test Flight beta testing, Test Flight was showing ~20 MB size, but now in App store it's 38 MB!
I uploaded it via Xcode, so I don't know the size of the uploaded archive.

Why did that happen?
