@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..

@zespy , hello!
I've been trying to do exactly same thing - print text with QText2DEntity.
And, unfortunately, that code doesn't work for me. I've been variating all parameters for a while and haven't reach any result - just nothing appears on screene.
Is it possible to add any other example or\and example project?

And thank's you for this thread, it's still biggest conversation about QText2DEntity usage

@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. :(
