Id like to place a label and a button (and a text field) in a horizontal layout. This works, but the baselines are unaligned. How to fix that?
The expected result is that the red lines (baselines of each control) are at the same height.
This is the FXML:
<?xml version="1.0" encoding="UTF-8"?>
<?import javafx.scene.control.Button?>
<?import javafx.scene.control.Label?>
<?import javafx.scene.control.TextField?>
<?import javafx.scene.layout.HBox?>
<HBox prefHeight="100.0" prefWidth="400.0" spacing="10.0" xmlns="http://javafx.com/javafx/8.0.65" xmlns:fx="http://javafx.com/fxml/1">
<children>
<Label text="Label" />
<Button mnemonicParsing="false" text="Button" />
<TextField text="Lorem Ipsum" />
</children>
</HBox>
Add an alignment attribute to the HBox with value "BASELINE_LEFT":
<HBox alignment="BASELINE_LEFT" prefHeight="100.0" prefWidth="400.0" spacing="10.0" xmlns="http://javafx.com/javafx/8.0.65" xmlns:fx="http://javafx.com/fxml/1">
<children>
<Label text="Label" />
<Button mnemonicParsing="false" text="Button" />
<TextField text="Lorem Ipsum" />
</children>
</HBox>

I am having one button. On click of that button. I am opening the stackpane which is right below it. For StackPane hard coded x layout values. So at first click the stackpane shows right below the button. The prob is when I maximize or resize the window it is not adjusting it's position(x).
FXML
<Button fx:id="searchCriteriaBtn" mnemonicParsing="false" onAction="#searchCriteriaAction" styleClass="redButton" text="Search Criteria">
<StackPane fx:id="searchCriteriaPane" alignment="TOP_RIGHT" prefHeight="150.0" prefWidth="200.0" styleClass="redBorder" translateX="239.0" translateY="-6.0" visible="false">

private void searchCriteriaAction(ActionEvent event){
searchCriteriaPane.visibleProperty().setValue(true);
searchCriteriaBtn.layoutXProperty().bind(searchCriteriaPane.layoutXProperty());
searchCriteriaBtn.layoutYProperty().bind(searchCriteriaPane.layoutYProperty());
}
I have found out the solution of overlay dropdown menu.

The first FXML is loaded into the AnchorPane with fx:id = "contentPane". For reasons I don't know ListView fx:id = "listView" doesn't resize during window resizing. Any ideas?
P.S. I use JavaFX 8
I have the following code to load the fxml file. I want to change the width of the button. I am able to access the two labels using fxmlLoader.getNamespace().get("id"), but for some reason I don't see the button inside ObservableMap returned by getNamespace(). Why is it so/

I created this as a wiki post. I found the solution by trial and error ( seems like the best way to learn programming ), but if somebody can show me a location on oracle docs where the following detail is listed, you have my upvote.
Answer
Just add fx:id to the button.
Before
<Button maxHeight="45.0" maxWidth="45.0" minHeight="45.0" minWidth="45.0" mnemonicParsing="false" prefHeight="45.0" prefWidth="45.0" style="" styleClass="alphabet-button" text="~" textAlignment="CENTER" textOverrun="ELLIPSIS">
After
<Button fx:id="button" maxHeight="45.0" maxWidth="45.0" minHeight="45.0" minWidth="45.0" mnemonicParsing="false" prefHeight="45.0" prefWidth="45.0" style="" styleClass="alphabet-button" text="~" textAlignment="CENTER" textOverrun="ELLIPSIS">
I'm new in JavaFX and have a little troubles:
I have an TabPane with several Tabs and I wanna make Tab titles invisible. So, user should not change Tabs by clicking on titles, but it will be changed in different way from menu..
How to make this Tab titles invisible/hidden? That's the question. I don't wanna hide whole Tabs or disable or anything like that, just titles.
Or maybe you have another, completely different idea, how to solve this in JavaFX. Maybe with another controls???
Thanks for any clue.
If you are not using Tabs then you don't need TabPane.
You can just introduce a list of content panes and switch them according to menu commands.
You can find a code example in next question: How can I implement the functionality of awt.CardLayout in my javaFX 2.0 application?
Conclusion of my research: This is not possible to do this in JavaFX. TabPane captions can be located on the top, left, right and bottom of the control, but cannot be hidden.
You can make this by wrapping TabPane in AnchorPane (root container) and setting up TabPane's topAnchor to negative number as much as needed.
Java code:
...
AnchorPane.setTopAnchor(myTabPane, -29.0);
AnchorPane.setBottomAnchor(myTabPane, 0);
AnchorPane.setLeftAnchor(myTabPane, 0);
AnchorPane.setRightAnchor(myTabPane, 0);
...

I am building a application in JavaFx 2.0 and would like to, when the application is deployed, to have it show up on the center of the window of a browser. I have looked for this topic in google and yahoo and found nothing. Any help is greatly appreciated.
Look at the source code for the JavaFX Ensemble example. The Ensemble application is configured to run to fill a browser window, no matter the size of the window. The way it is done is by configuration in the JavaScript which launches the app as well as via css styling of the div the application is embedded in.
Here is an extract of the relevant parts of the html.
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>JavaFX 2.0 - Ensemble</title>
<SCRIPT src="http://java.com/js/dtjava.js"></SCRIPT>
<script>
function javafxEmbed_ensemble() {
dtjava.embed(
{
id : 'ensemble',
url : 'Ensemble.jnlp',
placeholder : 'javafx-app-placeholder',
width : '100%',
height : '100%',
jnlp_content : '...'
},
{
javafx : '2.0+'
},
{}
);
}
dtjava.addOnloadCallback(javafxEmbed_ensemble);
</script>
<style>
html, body, #javafx-app-placeholder, #ensemble-app {
margin: 0;
overflow: hidden;
padding: 0;
width: 100%;
height: 100%;
}
</style>
</head>
<body><div id='javafx-app-placeholder'></div></body>
</html>
If you need something other than 100% coverage, you can the 100% tags to, say 75%, and adjust the css styling to get centering in the page with the margins you want.
The current Java packaging tools (e.g. the javafxpackager utility), do not allow specification of percentange widths. I've created a feature request for this in the javafx jira - you can create an account there to view the request. If you use those tools to generate your deployment html, then you might have to modify the deployment html by hand or by a post-processing ant script, as can be seen in the build.xml for the Ensemble sample application.
You can use combination of HBox and VBox panels in your FXML. Hier is my tested code:
<?xml version="1.0" encoding="UTF-8"?>
<?import java.lang.*?>
<?import java.util.*?>
<?import javafx.scene.*?>
<?import javafx.scene.control.*?>
<?import javafx.scene.layout.*?>
<AnchorPane fx:id="panel1" xmlns:fx="http://javafx.com/fxml" fx:controller="app.MainController">
<HBox alignment="CENTER" AnchorPane.bottomAnchor="0.0" AnchorPane.leftAnchor="0.0" AnchorPane.rightAnchor="0.0" AnchorPane.topAnchor="0.0">
<VBox alignment="CENTER">
<Pane fx:id="panel2"></Pane> <!-- YOUR CENTERED CONTENT HERE! -->
</VBox>
</HBox>
</AnchorPane>
The 'panel1' will stretch in the browser area. So the HBox and VBox will also. Because they have 'center' attributes for their childeren, the 'panel2' will be centered.

Might solve your problem
Try to use a StackPane as container. It will center all nodes it includes.
