I'm using java FX-8 and JDK 1.8,Netbeans 8.0.2.I want to open pdf on button click in my JavaFXML Application.I have triued pdf viewer plugins and iText but it doesn;t work.I have to pass variable value in pdf too.
how to open a GUI on top of another GUI? I have built a GUI and have a button that when pressed I want to open a new GUI which is another java application within the project, it seems pretty straight forward and I just need to insert 'new [name of application]()'
Button btnEdit = new Button(shell, SWT.NONE); btnEdit.addSelectionListener(new SelectionAdapter() { @Override public void widgetSelected(SelectionEvent e) { new edit(); } }); btnEdit.setBounds(76, 10, 75, 25); btnEdit.setText("Edit");
I am creating a mad libs type program. This section of code is for the user to be able to make their own mad lib template (that people will be able to fill out later). The normal blanks in a mad lib are for verb, noun, adjective, adverb, etc. I cam up with 13 or so of these buttons, but it would be nice that if the user wants to add a button that they think we missed, such as 'Person in the Room' or 'Silly Location'...that the user would be able to do this. I sort of pictured there being a button that says 'add button' or something like that. Is there a ways to do this with the way I've set things up?
public class MadLibs { public static void main(String[] args) throws IOException { //////////////////// //TEXT PANE WINDOW// //////////////////// //Set up a JTextPane object : The JTextPane is a specialized form of the JEditorPane //designed especially for the editing (and display) of styled text. final JTextPane pane = new JTextPane();
I have a program I wrote long ago. I change colors of buttons at times. Here is the code:
for(int Player=0; Player < 8; Player++){ //make them all background dealerLabels[Player].setBackground(new java.awt.Color(212,208,200)); } //Now make the new dealer green dealerLabels[dl].setBackground(new java.awt.Color(51, 255, 0));
The color of the buttons has always changed under XP but when I run the program on Windows 8 only the edges of the buttons change.
The class does get compiled but the submit button doesn't work?
/** * Orchestration class for Account */ import java.awt.*; //Importing the java.awt.* class import java.awt.event.*;//Importing the java.awt.event.* class import javax.swing.*;//Importing the javax.swing. class public class AccountDemo extends JFrame { /// initializes the variables in the container
so i'm supposed to create a jframe with only 1 button. each time you push the button it is supposed to go from red to green to blue to gray and back to red starting over. i can get is the background to change on the first click, then the button is useless for eternity. here is my code:
import java.awt.*; import javax.swing.*; import java.awt.event.*; public class Exercise2_59 extends JFrame implements ActionListener { JButton change;
Can I add actionListener to a button component without creating a reference to it? Look at my code below:
public void init() { setBackground(Color.red); //Create the layout setLayout(new BorderLayout(20, 5)); //Add buttons add("North", new Button("Red")); add("South", new Button("Yellow")); add("East", new Button("Cyan")); add("West", new Button("Magenta")); add("Center", new Button("White")); }
Or should I just do the usual instance.addActionListener(this) like myButton.addActionListener(this)?
I have been reading some java guides here [URL] .... and was trying to put a bit of what I have learnt into practice but am having some difficulty. Basically, using netbeans IDE I have created a new jFrameform so that I can place swing components in design mode. What I want to create isnt overly complicated but I just cant seem to get it. In design I have simply added a panel and a button. When I press the button I want to display an image I have located at:
/resources/images/numbers/1.png.
This is my code so far (most of it has been automatically generated from me adding things via design mode:
/* * To change this license header, choose License Headers in Project Properties. * To change this template file, choose Tools | Templates * and open the template in the editor. */
I assume I need something like below somewhere , do i need to create a draw method? if so how do I call it as it is expecting graphics2d as a parameter, what would I pass into it?
I tried a few things and I was unsuccessful at removing the border around my image button. It seemed simple enough when reading on StackOverflow but I'm still getting errors : s
ImageIcon cardIcon_1_1 = new ImageIcon("../images/empty.png"); JLabel cardImg_1_1 = new JLabel(cardIcon_1_1); cardImg_1_1.setBorder(BorderFactory.createEmptyBorder()); cardImg_1_1.setContentAreaFilled(false);

I'm using an applet it had to be in the initialize part of my program...
I've spent ages trying to implement an exit button into this code. Its the start of a GUI for a slot machine, the actual machine code is in a separate class and I haven't linked them yet. My question is where/how would the exit button be added? I've tried and failed a lot of times....
import java.awt.*; import java.awt.event.*; import javax.swing.*; public class SlotMachineGUI { public static void main (String[] args) { //create new jframe JFrame frame = new JFrame ("Slot Machine");
I want to add a button who refresh the tree the problem that i have not "DefaultTreeModel" in my class to do this ((DefaultTreeModel) jTree1.getModel()).reload(); and i try this jtree.updateUI(); but not work ....
I have buttons created on a frame and then I register the listener from a controller in a controller-view relationship.
When I click the button on the face, the action never executes for some reason. I thought maybe there was a problem registering the listener but I can call the buttons doclick() method and it executes as it should. Perhaps I'm overlooking something really obvious here but I can't see it.
again, when i click the button nothing happens. but if i add the following code
btnEight.doclick()
the actionPerformed invokes in theController as I intended.
You can see the entire project on GitHub so you can see the full context. The controller class contains the listener and the view class contains the buttons.
I've recently decided to learn Java on my own using internet material such as forums, blogs and you tube. Ive never programed before but through some research I concluded that Java is going to be on the mid spectrum of difficulty as far as verbiage goes. I ma in no way implying that Java is easy but instead closer to spoken English that c++ if my research is correct. So here is my attempt at a basic program where I click a button and it will make an image appear. Not sure where Im falling short
package clicktoimage; import java.awt.*; import java.awt.event.*; import javax.swing.*; public class Clicktoimage extends JFrame { private JLabel label; private ImageIcon image;
Projectsrccom.mypackageMyClass.java resourcesicon.pngmyexe.exe Right now I have to run the exe like this : - It has hardcoded the path of the exe :command = "cmd /c start /b cmd.exe /K "cd " + outputFolderPath + " && C:myfoldermyexe.exe " + "param1=value1 param2=value2 " ;
Process p = Runtime.getRuntime().exec(command); This works fine. But, When I package it as a jar I want to give a relative path to my resources folder. How can I make this happen?
I tried:File f = new File("resources/myexe.exe"); String path = f.getAbsolutePath(); but this "path" did not work.
Another way would be to extract the exe to a local path on the server, but there is a possibility that I could face permission issues.
I read the oracle doc example, i understand the concept but still nothing is happening on show,first ,next method of CardLayout in ActionPerformed. Code is highlighted where I am facing problem.
