I just started using JavaFX 11, and SwingFXUtils seems to be gone (or renamed?)
I tried to download it manually, but the module-system complained about import sun.awt.image.IntegerComponentRaster;, and I couldn't get it to work.
I need to convert Swing Icon to JavaFX image.
Since Java 9, SwingFXUtils has been moved to the javafx.swing module, under the package javafx.embed.swing.
See JavaFX 9 Javadoc and the new JavaFX 11 Javadoc, hosted at https://openjfx.io.
If you have any issue with your sample, make sure you are adding the proper VM options. See the samples from the getting started guide.
Probably you will need to add something like:
--module-path <path-to>/javafx-sdk-11/lib --add-modules=javafx.controls,javafx.swing
SwingFXUtils is still there if you have correctly added the javafx.swing module to your build path (see answer from José) but importing an internal class like sun.awt.image.IntegerComponentRaster is not allowed anymore.
To convert your icon you can try this:
Icon icon; // Your icon
BufferedImage image = (BufferedImage)((ImageIcon)icon).getImage();
WritableImage writable = SwingFXUtils.toFXImage(image, null);
Whether this works or not depends on how your icon was created but it is worth a try.

I would like to use native rendering for all the text in my application. For each Text, Label, etc. element I can do this
Text {
renderType: Text.NativeRendering
}
to trigger native rendering. I can also use the software renderer for the whole application:
QQuickWindow::setSceneGraphBackend(QSGRendererInterface::Software);
However due to some bugs with the software renderer and some performance issues, I would like to avoid that.
Is there a global switch to change the render type?
Since Qt 5.7, you can change the default Qt Quick text render type, but unfortunately only at build time. In order to change the default, you would have to rebuild libQt5Quick.so with QT_QUICK_DEFAULT_TEXT_RENDER_TYPE set to NativeRendering. For more details, see https://codereview.qt-project.org/#/c/121748/ .
If you have installed Qt using an installer from qt.io, install the source packages using the maintenance tool if you already haven't done so, navigate to qtdeclarative/src/quick, run qmake with the define, and build. Something along the lines:
cd path/to/Qt/Sources/5.8/qtdeclarative/src/quick
# NOTE: make sure to run qmake from the same/correct Qt installation
path/to/Qt/5.8/<spec>/qmake "DEFINES+=QT_QUICK_DEFAULT_TEXT_RENDER_TYPE=NativeRendering"
make -jN
If you have a self-built Qt installation, invoke make clean (or if you want to save time, just delete qquicktext*.o) before make to rebuild the library.
EDIT: Since Qt 5.10, it is also possible to specify the default text render type in C++ via QQuickWindow::setTextRenderType(). Just notice to set it before loading the QML content.
The environment variable QML_DISABLE_DISTANCEFIELD controls this.
If you put
qputenv("QML_DISABLE_DISTANCEFIELD", "1");
at the beginning of your main, you will get a nice and sharp text rendering everywhere.

Add this line first in c++ main function : QCoreApplication::setAttribute(Qt::AA_UseSoftwareOpenGL);
I have a javafx application that is supposed to run in fullscreen mode on a Windows tablet.
My problem is, when the keyboard appears, it's in QWERTY whereas my tablet is in AZERTY.
So the question is : Is there a way to use the system virtual keyboard or to switch the javafx virtual keyboard to AZERTY?
I found you question while trying to accopllish the same thing.
I spent a day trying to make javafx display an AZERTY keyboard and i found a solution!
Well let me be clear : javafx gave no way at all to have an azerty keyboard so you have to hack a little.
The solution bellow is not a perfect one and you'll have to repeat it each time you update javafx, but it will allow you to extrem customize the keyboard far beyong querty and azerty.
SOLUTION 1 (dirty but works )
You will need to edit a file in javafx file shipped with the JDK
STEPS :
GO to the JDK (in Mac : /Library/Java/JavaVirtualMachines/jdk1.8.0_77.jdk/Contents/Home)
Go inside jre/lib/ext and copy javafx jar called jfxrt.jar to a folder on your desktop.
Install EMACS if you don't have it and open the copied jar file with this software
Browse files list searching for com/sun/javafx/scene/control/skin/TextBoard.txt
the list is sorted from A-Z so use it (there is more than 6000 files).
Open it and HERE you are. Change characters to whatever order makes you happy. I joined the azerty order.
Save and copy back the jfxrt.jar to where it was. Done.
Note: don't try to extract the jar and rezip it, it won't work as jdk keeps an index list of files.
Result:azerty javafx virtual keyboard in action
SOLUTION 2 (Clean but i didn't finish it)
Whene i digged into javafx classes i found out that the class responsible for loading the TextBoard.txt file that lays out the keyboard is FXKVSkin
This class is meant to receive other type of keyboards than the lonly qwerty default one.
All you have to do is add this in your code :
textFieldThatYouUse.getProperties().put(FXVK.VK_TYPE_PROP_KEY,
"mykeyboard");
Where mykeyboard is a file you created like TextBoard.txt called MykeyboardBoard.txt (capitals letters are important).
FXKVSkin will look now for a file called MykeyboardBoard.txt, and here's where my adventure ended.
You will need to make FXKVSkin find your file, i tried by adding a file to the classpath at runtime solutions Here but it didn't work.
If anyone can solve this problem, please add it as an answer, it would be a less dirty solution.
Hope the solutions will help some non english speakers! :p
The definition of the layout is contained in jfxrt.jar (part of the Java install). It is described by TextBoard.txt. It is possible to browse in the jfxrt.jar with 7zip or similar programs. TextBoard.txt is in com/sun/javafx/scene/control/skin/
This file is loaded com/sun/javafx/scene/control/skin/FXVKSkin.java is responsible for loading the TextBoard.txt file. Browse the javafx source (included via the jdk and contained in javafx-src.zip) to see how it is processed. Maybe this will give you enough information to load your own TextBoard.txt file.
I am trying to chance the icon of the exe file created native bundling of javafx packaging but it still contains the default icon. Please suggest
primaryStage.getIcons().add(FileUtility.loadImage("icon.png"));
did not help, it only changes the title bar and task bar icon.
The ico file still gets generated and icon of the exe files remains the default one
I also tried to assign an icon in the project properties-> Deployment-> icon but did not help
I believe I have encountered the same issue and the solution is described in the following thread.
As a side note - neither specifying your icon in the build.xml file or via the project's options in the deployment section is going to work thus far, but it seems to be fixed in the upcoming release of 7u10.
I added response here How to set custom icon for javafx native package icon on Windows and thinks it is the same issue you started out with. However you seem to have moved on, but others might find it interesting...
I added src/main/deploy/package/windows/myapp.ico there and it finally worked :)
For you:
Create src/main/deploy/package/windows/ folder
Add icon with name ${project.build.finalName}.ico
Run mvn jfx:build-native
I haven't played with it extensively - just got it to work and wanted to share. So if you want to use icon with different name, I don't know how. Not yet at least. The ... section in the config section seems to be for webstart, so I haven't been using it. Hope you get it to work!
Answered at How to set custom icon for javafx native package icon on Windows
After completing building a flex project in Flash Builder 4.5, the project was exported using the
File -> Export Flash Builder Project.
After which some of the images stopped working (get the broken image icon). This has left me clueless and even search on the internet did not give me good answers...
I get the same problem time to time. Probably compiler / Flash Builder bug. But to be sure, you might want to check some basic things. First off: check that you have correct image urls. Secondly, ensure you are not using absolute source paths (e.g. C:\workspace\project\src\assets\images\image.png). Instead use relative path (i.e. assets\images\image.png).
If these are correct, check your build directory (default build directory for release builds in FB is bin-release) and see if the images are compiled there correctly. As I said, for some reason my FB does not always compile all the assets correctly, so sometimes I have to move them in manually. That is, you can simply drag and drop them from the source directory to the bin-release directory (although if you are using svn, you should be careful with this as it might copy also the svn metadata).
Other solutions you might want to try:
restart eclipse / FB (maybe it's simply out of memory)
delete the project from your workspace and import it again with no project information
change workspace and import the project there
I finally found the answer... made all the images bindable and just used the class to tag the images.
for example... instead of
if (draggedImage.id == "Chris" )
{
newImage.source = "assets/Chris.png";
}
changed it to
if (draggedImage.id == "Chris" )
{
newImage.source = pic3_icon;
}
I'm trying to display a "warning" icon next to a QLineEdit if it contains invalid data. I was trying to use QStyle::standardIcon(QStyle::SP_MessageBoxWarning) to get a standard pixmap and place it inside a QLabel, and in some cases this seems to work. When running Gnome the icon is displayed correctly, but when running under KDE no icon is shown. I assume that the warning icon is simply not included in the style used under KDE.
What is the preferred way to display a "standard" warning icon in Qt? Does there exist some list which shows which icons are included in every style? How can I get an icon from a style that I know includes the warning icon?
The last time I had a similar problem, I found this Qt labs discussion useful. It informed me that QIcon now (since 4.6 I believe) has a QIcon::fromTheme function that allows you to load an icon based on the Freedesktop.org Icon Naming Specification, and in addition provide a fallback icon to be used if the current theme does not have the icon in question.
What I did was then to include some very basic icons for use as fallback, and in general specify icons only by their Freedesktop names. This gave a theme-consistent look almost always, and the program still worked in cases where people were missing icons.
As for the warning icon, I'm guessing/hoping that every theme must have the one named "dialog-warning", and that it's what you're looking for.
I hope this helps.
Edit: Oh and, in case you don't know, it can be useful to look at for example the Tango icon set to get a rough idea of what the Freedesktop names correspond to (although it is of course theme-dependent).
Qt does bundle a number of images that are resources that you can use in your own code. These images are a superset of those available via standardIcon() You may want to verify that the particular image is included in the versions of Qt you're targeting.
The end result could look like the following:
QPixmap pixmap(":/trolltech/styles/commonstyle/images/up-128.png");
// use pixmap as needed
For anyone who wants to know how to do this in a Windows environment you can:
Create a qLabel in your custom class, and then in the constructor of that class create a QIcon with the style you want, convert it into a pixmap and use the QLabel::setPixmap() function to apply it to the one you created:
QIcon icon = style()->standardIcon(QStyle::SP_MessageBoxWarning); //or
//whatever icon you choose
QPixmap pixmap = icon.pixmap(QSize(60, 60));
ui->iconLabel->setPixmap(pixmap);
ui->iconLabel->setScaledContents(true); //you can set this to fill the
//dimensions of your qLabel if you wish.
