I am creating a javafx program in which i need to open a new fxml file in new tab dynamically.
I want that When user click on button a new tab is opened with new fxml file.
I Had no idea I can add tab as per design as much as i need but i want to do it dynamically when user click on button then only a new tab open.
I had also seen Questing but not working for me.
Please help me.
Thank you.
You can add tabs dynamically with
myTabPane.getTabs().add(myNewTab);
Create a new Tab with new Tab(), load your FXML and call
myNewTab.setContent(loadedFxmlRoot);
You can add tabs using this code, you need to confirm if your tabPane has this tab or no, else your program invokes SizeOfBounds exception.
if (!MessagePane.getTabs().contains(AllMessageTab)) {
MessagePane.getTabs().add(AllMessageTab);
}
SingleSelectionModel<Tab> selectionModel = MessagePane.getSelectionModel();
selectionModel.select(AllMessageTab);
AllMessageTab.setContent(_YourContentNodeHere);

I would like to make .txt-files accessible for my VaadinApp on a GlassfishServer.
Lets say I have a .txt-file, its content is 12345.
Now, when I click a button on my Vaadin StartPage, I would like to show the Data that has been written into this .txt-file.
I know how Java Input/Output is working but I have no clue how to make those files accessible for my VaadinApplication running on Glassfish 4.1.2.
Is there a folder I can put the .txt-file in, or how would I access the file?
Thanks
There is component named Label is available in Vaadin.
So that, the values which needs to be shown on the screen can be set as a caption/value for that object.
This can be done either through constructor or setter in that object.We will set the value through the setter as we need to display the value, once the button is clicked. That can be done like this.
Label sampleLabel = new Label();
sampleLabel.setContentMode(com.vaadin.shared.ui.ContentMode.HTML);
Now we will see how this can be added to the label, when a button is clicked.
Button sampleButton = new Button("Click");
sampleButton.addClickListener(event -> sampleLabel.setValue(<call the method that reads data from the text file>));
I hope this will be helpful.
Note: Basically you can place the file anywhere in the system.
But most preferred way.
If you are using maven to build the project, place the files in the resource folder.(src/main/resources)
I am searching for a way to change the view of an JavaFX FXML Application during runtime and save the result so, that it is present at the next Application start. Is there a way? I was searching the WWW but dont find any solution! For example: I have a function where i can add a label to a GridPane and can save the new added label. At the next start of my Application, the new label is present. Its for an DB Application where the user can add new Database fields for custom data.
I think, by using properties file(or DataBase) you can achieve this. Before closing the application update the current status into properties file. So that while opening the application once again read the properties file and update it to the previous status.
Code is at https://bpaste.net/show/b7aa0530f2ac (because of StackOverflow limitations)
I'm currently trying to use
//Menu.java
btn.setOnAction(event -> {
primaryStage.setScene(doubleclick);
});
to change scene from current scene to Scene doubleclick but it isn't found because it is in another class (Mouse.java). Also the variables in that class are needed for it to work. I've tried to copy over the code from Mouse.java to Menu.java but I don't know how to make that work.
So when I click button in the image above I see what is below:
...instead of the first content (main menu).
I have a Liferay project with Vaadin portlet.
I want to add icon to my buttons.
Button search = new Button("Search");
search.setIcon(new ThemeResource("img/silk/add.png"));
But dont know where i gonna put it? Now i put it in docroot directory.
UPDATE
No i try this.
Button search = new Button("Search");
search.setIcon(new ThemeResource("LifeRayVaadin-portlet/icons/add.png"));
But when i redeploy project in console get
09:34:05,773 WARN [404_jsp:109] /html/VAADIN/themes/liferay/LifeRayVaadin-portlet/icons/add.png
So your portlet is looking for the icons in /html/VAADIN/themes/liferay/LifeRayVaadin-portlet/icons/add.png.
You could create a directory icons under VAADIN and call:
search.setIcon(new ThemeResource("../../icons/add.png"));
ThemeResource without any path will look for the file in VAADIN/themes/yourtheme/ path and thus ../../ will get you (in this case) to /VAADIN/. I personally would never hardcode the name of a theme or a portlet in a project, because when it changes you have to go through every reference and change them.
You can put your images in $PORTLET-NAME/docroot/icons directory and call them using the Path
/$PORTLET-NAME$/icons/add.png
in your case it will be
Button search = new Button("Search");
search.setIcon(new ThemeResource("/$PORLTET-NAME$/icons/add.png"));
I am creating a window with two image buttons (using TriplePlay in my playN game).
Now I need dynamic text on these buttons. But when I add buttons with images (setIcon), I am not able to add Text on it same time. Please check the following code block I use now.
Interface iface = new Interface(null);
pointer().setListener(iface.plistener);
Styles buttonStyles = Styles.none().add(Style.BACKGROUND.is(new NullBackground())).
addSelected(Style.BACKGROUND.is(Background.solid(0xFFCCCCCC)));
Stylesheet rootSheet = Stylesheet.builder().add(Button.class, buttonStyles).create();
Root buttonroot = iface.createRoot(AxisLayout.horizontal().gap(150), rootSheet);
buttonroot.setSize(width_needed, height_needed);
buttonroot.addStyles(Styles.make(Style.BACKGROUND.is(new NullBackground())));
graphics().rootLayer().add(buttonroot.layer);
Button you = new Button().setIcon(buttonImage);
Button friend = new Button().setIcon(buttonImage);
buttonroot.add(you).add(friend);
buttonroot.layer.setTranslation(x_needed, y_needed);
Root nameroot = iface.createRoot(AxisLayout.horizontal().gap(300), rootSheet);
nameroot.setSize(width_needed, height_needed);
nameroot.addStyles(Styles.make(Style.BACKGROUND.is(new NullBackground())));
graphics().rootLayer().add(nameroot.layer);
name = new Label("YOU");// we need the dynamic string variable instead
friendName = new Label("FRIEND"); // we need the dynamic string variable instead
nameroot.add(name).add(friendName);
nameroot.layer.setTranslation(x_needed, y_needed);
here I have tried making a root then add button with images to it then making another root and add labels on it so that it will be show like text on the image buttons. But I know this is a bad way of doing it, and the alignment will not be according to what needed as it a dynamic text. Is there anyway to add a button, with image and a label on it?
Thanks in anticipation
Creating a button with text and an icon is trivial:
Button button = new Button("Text").setIcon(iconImage);
You can then change the text on the button any time you like, like so:
button.text.update("New Text");
If you want a button with a background image with text rendered over the background, then do the following:
Button button = new Button("Text").
addStyles(Background.is(Background.image(bgImage)));
Note that you will need the latest TriplePlay code (from Github) to use the ImageBackground. The latest code also supports Flash-style "scale9" backgrounds:
Button button = new Button("Text").
addStyles(Background.is(Background.scale9(bgImage)));
