spacing: 50

Thanks! Couldn't see the forest for the trees. :)

@SHRINIDHI-UPADHYAYA
Thank you for the code example! Since I am new to QML, this is very helpful and allows me to better understand how the DelayButtonStyle in QtQuick.Controls.Styles 1.4 is to be used with the DelayButton interface in QtQuick.Extras 1.4. (it can get a little confusing with the different versions of DelayButton).

Best!

It will be easier to implement this in C++, not in qml. But the documentation says, that performance of QQuickPaintedItem is not good enough. Is there any other way to implement game scene in C++ and integrate it in QML?

@ashajg
@aha_1980 's logging by categories (I didn't know Qt had that) is exactly the kind of thing I do in my own code (in qtMessageHandler) to achieve logging-by-individual-categories. It helps a lot if you put something like this in as you develop: it's much better to be able to switch on info message for, say, just your database accesses rather than having to switch all info message for whole program on/off.

Ok. I found the problem. The solution is here: https://github.com/FortAwesome/Font-Awesome/issues/12787

Hi,

thank you for your help. That works. I have to set the init value.

Hi @alcinos , if you give some sample code,it would help us to understand better and get to know what you want and where it is failing.

Here is a sample code from what i have understood:-
There are 2 Rectangles rect1 and rect2, rect2 is not visible,on pressing rect1 a timer is started which on triggered will make the rect2 visible and on releasing the mouse,you will get a console print that is "Rect1 Released"

``` Timer { id: dummyTimer interval: 2000 running: false onTriggered: { console.log("Timer Triggered") rect2.visible = true } } Rectangle { id: rect1 height: 100 width: 100 color: "red" anchors.centerIn: parent MouseArea { anchors.fill: parent onPressed: { console.log("Rect 1 Pressed") dummyTimer.start() } onReleased: { console.log("Rect 1 Released") } } } Rectangle { id: rect2 height: 100 width: 100 color: "green" anchors.centerIn: parent visible: false }

@J.Hilk

It's working fine on Windows.
Since this used to be a common mouse for Apple machines and it was discontinued in 2017, then how come it used to work back then? I'm asking you this because many of our users still use that mouse. So, we have to make this work for Apple mice on macOS.

Hi,

First of all use the Android Getting Started guide from Qt's documentation to the get the versions of the dependency that you should use.

Hunting for the latest and greatest at any price won't work for Android as each release of their NDK has a tendency to break the workflow of projects using it. Therefore you should use the guid already linked above. That will give you a development environment that is working.

Hi
The issues is most likely a missing DLL.
Maybe not for the exe but for one of the other DLLS.
If you have mutiple Qt installed, it might also be the reason. it took wrong ones.
But you never answered if you use visual studio compielr or mingw.

@SGaist
Thank you. I will do it that way.

@KillerSmath

So no way to manipulate that text message.
Thank you for your answer.

I am seeing a similar error, but I cannot track it down. The error is cropping up in a private qml file:

"Could not convert argument 2 at" "expression for index@file:///opt/Qt/5.12.2/gcc_64/qml/QtQuick/Controls/Private/TreeViewItemDelegateLoader.qml:84" "Passing incompatible arguments to C++ functions from JavaScript is dangerous and deprecated."

Is there a way to get a better stacktrace of this?

Edit: Somehow I got a better trace:

"Could not convert argument 2 at" "expression for index@file:///opt/Qt/5.12.2/gcc_64/qml/QtQuick/Controls/Private/TreeViewItemDelegateLoader.qml:84" "insertColumn@file:///opt/Qt/5.12.2/gcc_64/qml/QtQuick/Controls/Private/BasicTableView.qml:262" "addColumn@file:///opt/Qt/5.12.2/gcc_64/qml/QtQuick/Controls/Private/BasicTableView.qml:236" "expression for onCompleted@file:///opt/Qt/5.12.2/gcc_64/qml/QtQuick/Controls/Private/BasicTableView.qml:358" "__loadElement@file:///opt/Qt/5.12.2/gcc_64/qml/QtQuick/Controls/StackView.qml:825" "__performTransition@file:///opt/Qt/5.12.2/gcc_64/qml/QtQuick/Controls/StackView.qml:911" "push@file:///opt/Qt/5.12.2/gcc_64/qml/QtQuick/Controls/StackView.qml:605" "expression for onLoginComplete@qrc:/startup.qml:96" "onAccepted@qrc:/Login.qml:209" "expression for onAccepted@file:///opt/Qt/5.12.2/gcc_64/qml/QtQuick/Controls/TextField.qml:668" "Passing incompatible arguments to C++ functions from JavaScript is dangerous and deprecated." "This will throw a JavaScript TypeError in future releases of Qt!"

The call that starts this:

startup_stack.push({item: main_view, replace : true});

startup_stack is a StackView
main_view is a Component with custom objects defined inside it

I don't see a second argument here.

Edit:
Here is the offending line from the delegate file:

readonly property var index: model ? model["_q_TreeView_ModelIndex"] : __treeModel.index(-1,-1,null)

The error shows:

expression for index@file:///opt/Qt/5.12.2/gcc_64/qml/QtQuick/Controls/Private/TreeViewItemDelegateLoader.qml:84

Well the second parameter is a constant provided by the Qt qml file. Does this mean we have a problem with a custom index somewhere? Or is Qt complaining about itself?

Hello @zhangXianxiang and welcome to Qt Forum.

Firstly, can you define it better?

I suggest you to read the QtQuickControl2 Style documentation, it will explain how you can change the Style of your application.

QtQuickControl2 - Using Styles

Note: In this method, it's only changable before the qml file is loaded. If you are trying to change the style in runtime.

Check out this StackOverflow Post:
https://stackoverflow.com/questions/44951317/qml-qtquickcontrols2-change-style-properties-at-runtime

Hi and welcome to devnet,

.qrc files are not loaded, they are processed so that the files linked in it are built in your application. So there's nothing special you have to do except referencing them properly in your .pro file.

@KroMignon
Yeah, right. I didn't see that close curly bracket! :)

anchors.centerIn: parent } <= This Button { id: myButton

@J.Hilk said in How can I draw an image into TextArea without HTML?:

@raven-worx I didn‘t know there were classes one isn‘t supposed to modfy, look at that...

Since this is in qml, you could simply add an Image element on top of your textarea,
it will require a good amount of micro managment, aligning, show not to show logic etc. but should be possible.

I'm now drawing image on top of textarea,but the performance is very bad(will cause the textedit blink).
My solution is to draw image on QImage and then create an texturenode add into TextNode.but draw QImage is low performance,is a way can draw image to the texture directly by opengl?
