View Replies View RelatedI am new to javafx I start using it instead of swing i used the scene builder for my forms the problem i faced i don't know how to have main screen with menu bar at top and depending the select from the menu it will open other windows and those window must be inside my window just like for example netbeans.
I don't need to open new window in separate i need all windows inside my main window and controlling over them minimize maximize perhaps.
I am doing an online course in Java. Mainly for Windows Applications using Eclipse.In the course that I m doing the Instructor has said that most Java programmers dont bother with GUI builders and tend to hand code everyhing. Is this correct? I ask because my previous language I made good use of a GUI builder due to its ease and speed.
Is this because the code is more stable than the generated code offered by GUI builders in Java or is it just better to have full control and to gain a better understanding on how it all works with the layout managers?

View Replies View RelatedI am having the hardest time trying to figure out how to display an array in a 1-window GUI.
I can display 1 book separately, by basically ignoring the array and creating a new object for each book, but I need all 5 books to display in one window, and that's where I'm lost. I'd really like to use the arrayI built to generate the books in the GUI. The information of each book appearing horizontally, and the different books appearing vertically.

So, Iv'e been trying to make a simple Text Based RPG with Java, and it is going quite well, and my friends want to play it too but they aren't very tech savvy, so it's hard to tell them to get an IDE or use the CMD, so I wanted to know if there was a way to make my text-based game into a window, like using JFrame or something. All i need is a window that displays the text, and a bar on the bottom that lets the user input what they want (Kind of like a CMD).
I want it sort of like this window: This Pic
Any way to get my Java window to open with a certain width and height. I've been googling and haven't found to much valuable information. Here is what I have so far.
import javax.swing.*;
import javax.swing.event.*;
import java.awt.*;
import java.awt.event.*;
public class JavaWindow{
//Bring up the frame.
private JFrame f = new JFrame("JavaWindow");
[Code] ....
When you compile that it runs a small window. I would like that window to be bigger when the file opens.

View Replies View RelatedI am writing a ComputerBaseTest application with Netbeans. I have each question on a panel and I want the questions(panels) to be switched, viewing the previous and the next question on a single frame, but I do not know how.
I only understand frame switching if each questn is to be on a frame but each score on each question (frame) do not sum up to give the overall score at the end of the test. Using multi-frame shows a sign of bad programming.
I did an implementation which is an extension of javafx.scene.control.ComboBox
Inside I imported the Class ComboBoxListViewSkin
import com.sun.javafx.scene.control.skin.ComboBoxListViewSkin;
I think this might be the reason as this comboBox is not recognized at the import to the scene builder library. I can show up the import dialog of custom controls, but my custom ComboBox is not showing up. All other implementations are there correctly as they are loaded from my customControl.jar file
I use the ComboBoxListViewSkin for the functionality to scroll to an item in the combo as a user types a letter on the keyboard.
I do this by:
/**
* This method scrolls the itemView of the items to the first item starting
* with the given char or string
*
* @param pressedKey
*/
public void scrollToChar(String pressedKey) {
String value = pressedKey.toUpperCase();
for (Object userEntry : getItems()) {
[Code] ....
I really need to show up my custom Combo in the scenebuilder, as otherwise the rest of my fxml is not editable in sceneBuilder 2.0 ....
I thought I had a simple idea for creating a control that would let me get some of the behavior of a card pane. This is the entire control:
import javafx.beans.property.BooleanProperty;
import javafx.beans.property.SimpleBooleanProperty;
import javafx.beans.value.ChangeListener;
import javafx.beans.value.ObservableValue;
import javafx.scene.Node;
[Code] ....
The idea is pretty simple; extend StackPane, add an active property, bind the visible and managed properties of the pane to the active property, and, whenever the active property is changed to true, iterate sibling nodes de-activating any siblings that are also of the type Card.
However, this doesn't work with Scene Builder. While trying to debug, I created an ExtStackPane:
import javafx.collections.ListChangeListener;
import javafx.scene.Node;
import javafx.scene.layout.StackPane;
public class ExtStackPane extends StackPane {
{
getChildren().addListener((ListChangeListener<Node>) c -> {
System.out.println("ExtStackPane children change: " + c.toString());
});
}
}
All this does is log list change events. However, I was very surprised by the output when working in Scene Builder. I added both controls to Scene Builder and did the following:
0) Added an ExtStackPane
1) Added a Card to the ExtStackPane
2) Added another Card to the ExtStackPane
3) Added a Label to the first Card
4) Added a Label to the second Card
5) Changed the text of the first Label to Hello
6) Changed the text of the second Label to World
7) Set the first Card to active
8) Set the second Card to active
I get the following output:
1)
ExtStackPane children change: { [Card@5b9067b3] added at 0 }
2)
ExtStackPane children change: { [Card@6b6328bd] added at 0 }
ExtStackPane children change: { [Card@6aca8cc5] added at 1 }
[Code] ....
This is what things look like in Scene Builder:
Does Scene Builder recreate the entire hierarchy every time I make a small change? Here's an application that does the same as the manual steps I performed in Scene Builder:
import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.Label;
import javafx.stage.Stage;
public class CardApplication extends Application {
[Code] ....
The output when running the above is:
1)
ExtStackPane children change: { [Card@6dfaa767] added at 0 }
2)
ExtStackPane children change: { [Card@6aa2c411] added at 1 }
[Code] ....
The behavior is obviously a lot different than when I'm working with the control in Scene Builder. What Scene Builder is doing to change the behavior of my Card control so much? Does my Card control break some rule(s) I'm not aware of?

My intention is to see the real reference values (memory locations) of 2 StringBuilder objects as below:
StringBuilder sb2 = new StringBuilder("123");
StringBuilder sb3 = sb2;
System.out.println(sb2);
System.out.println(sb3);
I was expecting a printout like
@S234853
@S984724
But all I got was 123 printed twice. How can i print out the reference values instead of what is inside the StringBuilder object ?
I'm using Scene Builder 2.0 and have added an ImageView to the parent AnchorPane. I've added my PNG files for the app icon and the various buttons. I select the ImageView in Scene Builder and then crawl the filesystem to the project package folder and select the PNG for the Image. The assigned image is displayed in the Imageview in Scene Builder in both design mode and Preview mode.
While everything else shows up properly when the app is executed, the image assigned to the ImageView does not display.
From the FXML file:
<ImageView fx:id="ivBRULogo" fitHeight="64.0" fitWidth="64.0" layoutX="14.0" layoutY="14.0" pickOnBounds="true" preserveRatio="true" AnchorPane.leftAnchor="14.0" AnchorPane.topAnchor="14.0">
<image>
<Image url="@BRU_PE_B_64.png" />
</image>
</ImageView>
What might be occurring between the compiled app and what Scene Builder generates?
I am trying to align the core/middle side color of a cube, index 4, with the bottom middle color of the same side, index 7. (Each side has values 0-8 where 0 - is the top left corner, 1 is the top mid corner, 2 is the top right corner, 3 is the middle left corner, etc).
In addition to lining up those two colors, I am also making sure that the neighbor color of index 7(the color that it is attached), in this case the bottom color, matches with the top core/middle color. I will attach some pictures and a print out to show what I am talking about...
However, in my code when I am trying to align all of these up together, it does not go into the while loop. Each of the loops essentially is trying to get a match of same color with index 4 and 7, as well as making sure that index 7's neighbor color (the bottom color, in this case) matches with the top color.
Here is what I have tried:
private void alignSideColor(){//make the bottom colors neighbor match with a middle side value and rotate it to the top, for the top cross
if(cube.bottom.square[1].charAt(0) == topColor){
while(cube.front.square[7].charAt(0) != frontColor && cube.bottom.square[1].charAt(0) != topColor){
rotateBottomClockwise(1);
System.out.println("Trying to align side color...");
[Code] .....
The print out of the ELSE IF is:
alignment is: W-G and tops: R-R
NOW ITS ALIGNED
even though the sides, index 4 and 7, are NOT aligned with each other
I have also tried the same thing but with out the 2nd condition in each while loop, and although is DOES enter the while loop, it does not perform correctly -- index 4 and 7 WILL have matches colors, but it does not check to see if index 7's neighbor matches with the top color.
Here is how it prints out
** ** ** G7 B6 Y1 ** ** **//this portion is the back of the cube
** ** ** R6 W5 O4 ** ** **
** ** ** R3 W2 O1 ** ** **
B3 G4 Y9 W9 O8 Y7 W3 B4 G9//this portion is the left, top, and right of the cube
B2 G5 R8 W4 R5 Y6 O2 B5 G8
O7 W8 R9 B7 B8 B9 R1 R4 R7
** ** ** O3 O6 O9 ** ** **//this portion is the front of the cube
** ** ** Y2 Y5 Y8 ** ** **
** ** ** B1 G6 W7 ** ** **
** ** ** Y3 Y4 G1 ** ** **//this portion is the bottom the cube
** ** ** R2 O5 G2 ** ** **
** ** ** W1 W6 G3 ** ** **
Here is the cube showing the top, left and front side
Here is the left and bottom side. As you can see index 4, G5 -- yes that is a 5 lol -- does not have the same color as index 7, W8.
I need to rotate the bottom until W8 is aligned with a middle white value. An examples of a neighbor is: W8-R2
I decide to make a new GUI just for fun and practise and i want to learn more about Layouts.. right know i am try to understand some staff about GridBagLayout.
I want to make a GUI with this Layout :
So..first i am a frame with borderlayout then i put a JMenuBar and bla bla bla and i create panel with GridLayout which i put on myFrame.add(panel1,BorderLayout.WEST) and also i make an another JPanel which i put of the Center of main Frame (myFrame.add(panel2,BorderLayout.Center))
when i run the program i get this GUI :
Now the problem is that i can't put the JButton on the top of the gridLayout just to look like the first picture.. i Read about anchor and i try to
gbc.anchor = GridBagConstraints.NORTH; but without results.. still the components are on the middle of the JPanel..
Here is my Code () :

import java.awt.BorderLayout;
import java.awt.Dimension;
import java.awt.GridBagConstraints;
import java.awt.GridBagLayout;
import java.awt.Insets;

public class TextBoxesGUI extends javax.swing.JFrame {
public String NewText;
public TextBoxesGUI() {
initComponents();

Really need some simple and complete example on how to extends components (graphically and functionally) for primefaces 5.
For example I can't figure how to add custom attributes to existing component or define default values for existing attributes.
Is there any tutorial or a basic common way to achieve this goal or each component have to be extended in its way?
