In the JavaFX Scene Builder, is it somehow possible to view the FXML code for the current layout without saving to a file and view the saved file?
right click on the root node in scene builder and then choose copy . and paste it in any text editor.
out put :
<Group id="sb-clipboard" xmlns:fx="http://javafx.com/fxml">
<fx:define>
<AnchorPane id="AnchorPane" maxHeight="-Infinity" maxWidth="-Infinity" minHeight="-Infinity" minWidth="-Infinity" prefHeight="400.0" prefWidth="600.0">
<children>
<Button id="button1" layoutX="140.0" layoutY="104.0" mnemonicParsing="false" text="Button" />
<RadioButton id="radioButton1" layoutX="283.0" layoutY="172.0" mnemonicParsing="false" text="RadioButton" />
<ToggleButton id="toggleButton1" layoutX="94.0" layoutY="234.0" mnemonicParsing="false" text="ToggleButton" />
</children>
</AnchorPane>
</fx:define>
</Group>

I have an app with the following structure:
<GridPane>
<columnConstraints>
<ColumnConstraints fillWidth="true" hgrow="ALWAYS" />
</columnConstraints>
<rowConstraints>
<RowConstraints fillHeight="true" vgrow="ALWAYS" />
</rowConstraints>
<children>
<FlowPane fx:id="flwPictures" GridPane.columnIndex="0" GridPane.rowIndex="0"
GridPane.fillHeight="true" GridPane.fillWidth="true"
GridPane.hgrow="ALWAYS" GridPane.vgrow="ALWAYS" >
<padding>
<Insets top="2.0" bottom="2.0" left="2.0" right="2.0" />
</padding>
<children>
</children>
</FlowPane>
</children>
</GridPane>
I need the FlowPane to fill the size of its parent container of the GridPane. The Nodes are added dynamically based on user selection. So far what I observe is that flow pane is not filling.
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">
JAVA
#FXML
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.
<MenuButton mnemonicParsing="false" nodeOrientation="LEFT_TO_RIGHT"
styleClass="redButton" text="Search Criteria" textFill="WHITE">
<items>
<MenuItem mnemonicParsing="false"
style="-fx-background-color: transparent; -fx-padding: 0; -fx-margin: 0;">
<AnchorPane minHeight="0.0" minWidth="0.0"
prefHeight="500.0" prefWidth="345.0" styleClass="noborder">
<children>
<HBox layoutY="156.0" minHeight="185.0" minWidth="345.0"
prefHeight="185.0" prefWidth="357.0" />
<HBox layoutX="5.0" layoutY="316.0" prefHeight="35.0"
prefWidth="348.0">
<children>
<Text layoutX="7.0" layoutY="335.0" strokeType="OUTSIDE"
strokeWidth="0.0" text="Template Name">
<HBox.margin>
<Insets right="5.0" top="9.0" />
</HBox.margin>
</Text>
<ComboBox fx:id="templateNameComboBox" layoutX="94.0"
layoutY="330.0" prefWidth="248.0" promptText="Select Template Name">
<HBox.margin>
<Insets left="7.0" />
</HBox.margin>
</ComboBox>
</children>
</HBox>
</children>
</AnchorPane>
</MenuItem>
</items>
<HBox.margin>
<Insets left="6.0" />
</HBox.margin>
<cursor>
<Cursor fx:constant="HAND" />

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);
...
