Hello, I also want to know how to get text input from the user and set that text on a 3d object. I came here in hope but it makes me sad when I found out that no one answered this post yet. I am bumping this post in hope that I will get some help. Please answer me. Until then I will play online casino games which I have found with the help of this playcasinoscanada.com site. I am waiting for your reply, I hope I will get it soon.

@raven-worx i cannot specify Layout.alignment in string creating Text because i get error that this property doesn't exist

I found out that I can reproduce this behavior by setting QT_DISTANCEFIELD_DEFAULT_BASEFONTSIZE, QT_DISTANCEFIELD_DEFAULT_SCALE and QT_DISTANCEFIELD_DEFAULT_RADIUS variables. With these, the problem occurs even on Windows. Not sure whether it's the same problem or not, but if QT_DISTANCEFIELD_DEFAULT_RADIUS is NOT DIVISIBLE by QT_DISTANCEFIELD_DEFAULT_SCALE, the problem occurs 100% of time (some letters will disappear). Example: export QT_DISTANCEFIELD_DEFAULT_BASEFONTSIZE=128 export QT_DISTANCEFIELD_DEFAULT_SCALE=12 export QT_DISTANCEFIELD_DEFAULT_RADIUS=96 // If I set this to 95 or 97 or anything not divisible by 12, it will break. Can someone explain me what these distancefield environment variables do and whether this is an intended behavior?

@J-Hilk thank you

No need to calculate the position, use linkActivated signal handler https://doc.qt.io/qt-5/qml-qtquick-text.html#linkActivated-signal

Is it possible to to extend QLabel and implement my own paintEvent() that draws the text and draws the svg image? It seems to work, but would problaby take alot of effort to get it right (i.e. to get the image in the right location everytime). void MypLabel::paintEvent(QPaintEvent* event) { QPainter painter(this); const auto pos = QPoint(0, 16); painter.drawText(pos, this->text()); const auto posPixMap = QPoint(30, 0); auto size = QSize(16, 16); auto pixMap = QIcon(":/Resources/smiley.svg").pixmap(size); painter.drawPixmap(posPixMap, pixMap); }

@mrjj Thank you for your answer. So I tested to remove the text rectangle passed to the drawContents() function, and indeed the global clipping was applied instead.

@diredko you can take a look at the Scalability section of the documentation The calculating scaling ratio section has an example that used to help me a lot when I first was confronted with this issue.

I resolve it. I setted font of text as property of QML Text component. (Like font.family : parent.fontfamily) and on Qt 5.7's QML, there are no enough options to control font properties. so, I moved to C++ side and set a whole application font. QFont font = someClass.getLangFont(); //set property of font instance here // such as hinting policy, style etc. QApplication::setFont(font); now it looks very cleary... thank you..

I've got the same issue with Qt3DExtras::QText2DEntity. But I found the workaround. Look like there is a bug? in implementation of Qt3DExtras::QText2DEntity that prevents internal initialization (QText2DEntityPrivate::setScene is never called). This happens when scene is already visible and Qt3DExtras::QText2DEntity is created with parent entity passed to constructor. The workaround I used to make it work is to pass nullptr (which is default) as parent in constructor and call ->setParent(parentEntity) in separate call. m_text2dLabel = new Qt3DExtras::QText2DEntity(); m_text2dLabel->setParent(parentNode);

@aha_1980 Thanks for the answer . I will try your sugestions and see how it goes. I've done all this text to ASCII in console codeblocks C++ but it seems that i need a gui to it. I am not as good in Class'es and things like that. I will try it anyways. An example could be more than good for one letter . i could do the rest alone :P . Have a good night

Looks strange. There is one example called fontDatabase in Qt examples. Can you compile in msvc and check this font is available ?

@romsharkov said in Incorrect Font Metrics: @raven-worx Didn't know about those methods, just tested it, for the lower case letter "g": QFontMetricsF::leftBearing() returns: -4.17188 QFontMetricsF::rightBearing() returns: 0.6875 But even if I add the (negated) leftBearing to the total text width it still doesn't cover the tail entirely, so what's wrong here? are you sure?! Those values seem to be correct / make sense according to your posted screens. Make sure that you add the absolute value (qAbs() for example). Also keep in mind that those values are only correct for the given font-size and that you can't add negative values to a image width. I guess you are just doing incorrect calculations. Can you show the code of the calculation?

Hi, As silly as it may sound but wouldn't removing << std::endl from the checking line be enough ?

Ok, thanks a lot! Marked as solved!

QComboBox {background-color:rgb(190,190,190);color:black;padding-left: 10px;padding-right: 30px;border-style: solid;border-width: 0px;} "padding-left: 10px;" the padding will shift the combo-box displayed content form the left edge QComboBox::drop-down {subcontrol-origin: padding; subcontrol-position: top right;width: 40px;border: 0px ;} "subcontrol-position: top right;" and the above will position wot text to the right. Hopefully this helps.

@Rohith instead of converting the unicode string to the escaped characters send it directly in binary form. When you have a QString already you can call QString::toUtf8() and send the returned QByteArray directly. On the client its enough to do QString::fromUtf8( receivedUtf8ByteArray.constData() ) It depends how you implemented the transfer. But theoretically it should be enough to replace your unicode escaping code on the server with this approach.

I can't say that I understood your code, but if you'll change the return value of your reading method (read(), I presume) to QStringList, then you can display it with ListView in QML like this: ListView { //Layout.preferredHeight: childrenRect.height model: myFile.read() delegate: Text { text: modelData } }

Please report a bug at bugreports.qt.io.

@Qjay You can get text like this, Create instance of search.qml means like Search(this is your search.qml file instance, first latter should be capital of your qml file) { id: searchText } 2 In search.qml file create property like property alias Name_of_variable(like textOfSearchField): id_of_textfield(search_text.text) Now wherever you want to use, can do like this. searchText(id_of_instance).Name_of_variable You will find exact value as you passed in search.qml file

You can use QSqlQuery to run the select statements and loop the resultset with next() like in VRonin´s example. If you comma seperate the columns like in VRonin´s example you can open this file in excel. One more option, if your on windows is to use ODBC Excel Driver to generate the Excel file. With this you can use QSqlQuery to create tables and insert rows.

The application runs in RAM, with all the qt dll useful for the deployment. Is it possible that a RAM corruption can cause a problem related to interface (font corruption, background image corruption...)? Thank you

Hi Have a look at http://doc.qt.io/qt-5.5/qtextobjectinterface.html#details http://doc.qt.io/qt-5/qtextobjectinterface.html and the "Text Object Example" It seems possible to create your own widget to support such feature but I have no tested it and do not know if object would receive events. also docs says "Copy and Paste operations ignore custom text objects."

Aliasing problem ?

Ok, so what happened before is that the item you added was destroyed before it could be shown

You need to add the module path to QML import path. You can do that in 2 different ways: Add "<path-to-qml-material>/modules" to your QML2_IMPORT_PATH env var. Or add it in your main.cpp using engine.addImportPath("<path-to-qml-material>/modules/");

So as it turns out, compiling Qt 5.5 from git seems to solve this problem. I tried my demo program, as well as Maroon, and both display text by default (without having to set renderType to Text.NativeRendering). Dang it. That's what I get for trying a pre-release version. Thanks for the suggestion.

@JackCWallace You need to set an visual parent to the newly created item using setParentItem. For this you will have to create a QQuickItem ofcourse.

My problem is image delegate only. I found addiotional regularity: problematic delegates have the same picture as last top delegate hidden during scroll down within ListView. It seems scrolling out delegate from visible area forces it's image repaint in other delegates, which are in visible area. This repaint seems to hide the text element, declered with z-order above the image. Reset the visible property (visible=false, visible=true) at end of each scrolling (using onMovementEneded) solves the problem. But, i don't want to pay the repaint price of such solution as my application is running on embedded device.

I found a workaround: Define environment variable within Qt application startup context: QML_USE_GLYPHCACHE_WORKAROUND = 1 Look on this topic: https://forum.qt.io/topic/39803/font-rendering-bug-on-some-android-devices/7

Fixed by using a different font.

thank you very much....

ty, I have downgraded some packages (libglapi-mesa f.e.) and reinstalled some others. nopw everything is fine!

Thanks @p3c0 Based on the documentation, QtDeclarative has already been deprecated in favor of the two new classes: Qt Quick and Qt QML. QQuickPaintedItem can be use as convenient way to port QDeclarativeItem-based classes that use the QPainter API. I've been searching on the internet how to render text on QSG nodes but to no avail. I'm still stuck into this problem. :(
