I have made a little chat program with java(ecplise) but i want build it and if a user opens it is is going to run in the backgroundprocess. I don't know if i have to edit my code or Export it differently.
i am trying to make a platform game in java and to do this im trying to make a scrolling bacground. i can get the background image to scroll. However, i cant get the image to scroll forever, here is the code.
GamePanel class ( the jpanel ) public class GamePanel extends JPanel implements ActionListener{ static ArrayList<BackGround> store = new ArrayList<BackGround>(); public GamePanel(){ setFocusable(true); Timer time = new Timer(5,this); time.start(); store.add(new BackGround(0,-200));
the problem i have is that i want the bacground to loop. however, once the first instance of the background is done scrolling it freezes and doesnt load anymore. here is the code for adding a new background to the list
I am trying to go about making this applet a bit different then normal. The issue I am having is it is drawing an applet but, not the right dimensions, it's able to be resized, lastly the background color is not being set. I mean, I suppose I could call paint() and just draw it out but, I read that I could make the applet pop out to the dimensions I would like. None of this is working sadly.
I have been following a 2d side scroller tutorial in java and have got the basics working, I changed the code a bit to make it so that the tiles and background are always moving, this worked as i intended.Within the character class:
if (speedX < 0) { centerX += speedX; } if (speedX == 0 || speedX < 0) { bg1.setSpeedX(0); bg2.setSpeedX(0);
[code]....
I wanted a way to make it so that if the character moves left, the tiles + background move slower. I am having issues with variable scope and setters/getters. Within the main game class, I have the code:
case KeyEvent.VK_LEFT: character.moveLeft(); character.setMovingLeft(true); break;
How can i include an if statement within the tile class that reads whether the character is moving left (determined from a keyPressed event in the main game class) and adjusts the speed of the tiles accordingly?I want to write something to the effect of:
I am developing in Android Studio and I made a simple background, the actual resolution of the image is 1440 by 2560. I made it that resolution so, 1, it is easier to scale down than up, and 2, in android studio i use a nexus 6 as my preview. When I plugged in my gs4, not a 1440 by 2560 display, the background wouldn't show up when I ran it on my gs4(galaxy s 4). How do i get my background to scale and display on any display size.
In my web application i want to upload file to drop-box. I am getting file name from browser.Is it possible to upload file to drop-box with only file name.
Isn't changing my backgrounds in my MouseAdapter I keep getting these errors:
at javax.swing.JComponent.processMouseEvent(Unknown Source) at java.awt.Component.processEvent(Unknown Source) at java.awt.Container.processEvent(Unknown Source) at java.awt.Component.dispatchEventImpl(Unknown Source) at java.awt.Container.dispatchEventImpl(Unknown Source) at java.awt.Component.dispatchEvent(Unknown Source) at java.awt.LightweightDispatcher.retargetMouseEvent(Unknown Source)
JFrame{ JPanel(That MenuBar at the top) JPanel(That panel at center with table){ JScrollPane{ JTable } } }
I want to add my custom image to that grey space right there. I guess it is a JScrollPane, because I added that orange background on JPanel that contains it. But when I add this code to my custom class of JScrollPane:
@Override public void paintComponent(Graphics g) { super.paintComponent(g); if(background == null){ background = new ImageIcon(ClassLoader.getSystemResource("tableBg.png")).getImage(); } g.drawImage(background, 0, 0, null); }
The result is the same, no changes.
Then I read some documentation. I found this method:
scrollPane.getViewport().setBackground(Color c);
It works, but it accepts only color and I want to add image. Is there any way to do that? Do I need to subclass JViewport and use paintComponent ? If yes, then how to make getViewport() method return my custom subclassed version?
This is my code and it works! But how/where do I set a background image for it to appear as the background of my calculator? The code I have for it is this -
import javax.swing.*; import java.awt.*; import java.awt.event.*; /** * Program using SWING components to create a Christmas themed Calculator. */ public class ChristmasCalculator implements ActionListener
import javax.swing.*; import java.awt.*; import java.awt.event.*; public class sample{ public static void main(String args[]){ JFrame frame = new JFrame(); frame.setSize(300,300);
[code]....
To limit the amount of drawing done i want unmoving objects to be painted once. So i set a boolean. When it first load the boolean is false so it draws then after first draw i never want it to draw the objects agian but leave them on the screen. Now in this if you run it you get a black screen.
If you didnt have the "getContentPane().setBackground(Color.black)" it would work fine and show a blue brick. Is there something I don't understand about the setBackgound Function that makes it automatically redone even when not called? and if so how do i overwrite this?
I have tried to set a background Image to a calculator usinf JLabel. However I've ended up with my image to the left of my calculator , my calculator textfield becoming the size of the background image and then all my buttons below it. Like so(if you can view the image)..Calculator.jpg
How can I fix this so the background is behind my buttons and my text area is a normal size again.
So I have basic java knowledge from 1st year of college and I wrote a program recently that sends keystrokes with the Robot class. Now I would like it to do the same but to send it to a window that isn't my active one.. I've searched and from what Ive found it seems like you cant do that in java, I need another language like C# (whick sux for me since i dont know any other then java).. Is this true? If not how would i send something to notepad for example while it is not the active window?
Actually i want to develop a game for that i need a background with a image and over this background i want to move some objects (which are images) and also want to add some button.
Here is my Code.
The Main Class
package last; import java.awt.*; import javax.swing.*; public class Last extends JFrame{ public static void main(String[] args) { Last l =new Last(); l.setSize(900, 600);
[Code] .....
When i execute the above program only the background image is shown.
I am trying to put a button (in a container) on a jpanel in a jframe with a background but the container is covering up the background with white color.Below I have an excellent SCCE:
I would like to learn how to add an image background to a window in java that I can put controls like buttons, textboxes, and checkboxes in front of. I already tried using a JLabel with an ImageIcon but I cannot overlay controls over the JLabel. From what I understand there are multiple ways to do this. What is the best way and how can I do it?
