I want the Jbutton Button1 icon to change when i click it howerer i am getting the error can not find symbol for the code in the actionPerformrd method.
Recently I have been working on an executable launcher. I tried to get the executable icons and set them on the JButtons. Still there are some problems. Here is a part of the code:
try {
button[i].setIcon(FileSystemView.getFileSystemView().getSystemIcon(new File(getConfig("path." + (i+1)))));
}
catch (NullPointerException ex) {
}
Here the getConfig() method is already defined to get a string in a "properties" file. However, the icons are very small and they don't fill the entire button.
How can the icon fill the entire button (for example, having a custom size of 48x48, or automatically filled the button)? The frame will not be resized.
Here is the whole code...
import java.awt.*;
import java.awt.event.*;
import java.awt.image.*;

Is it possible to go from one method to another when a jbutton is clicked?

I cannot...(actually do not know) how to change the actionlistener (actionPerformed) after the second click in an array of JButtons. This is how the program performs right now.
On the 1st click on the grid, the border of the button clicked will change to 'blue' and another button will change its boarder to 'red'. on the next click the same action is performed.
What I need is to change action when the 'red' bordered button is clicked, lets say change the color of the buttons from the 'red' to the 'blue' buttons.(x 3 buttons).
The logic about how to perform the final result I think I can do on my own but my problem is how to change the action when the red bordered button is clicked.

So I'm in the middle of creating a model program with voxels. I want to be able to see how the model looks like when I'm in for example my documents (not inside the real program). I want it to show an image of the model, just like a png file shows its image. I've tried looking around, but I've only found threads about changing exe files icon.
Image example:
So, is this possible in Java or do I need to use c/c++ (with JNA) to make this possible?
Or is it not possible at all?
So I have got a button and there is this property assigned to it:
button.setIcon(new ImageIcon("srcimage.jpg"));
The icon is not displayed in full, as it is larger than the button. What property can I use to resize the icon? I have tried few and it did not work.
Any way to resize an ImageIcon when placing it on a Button so that I don't have to physically rezize the image file?? I am writing an Application, not an applet, so the getImage method won't work.

I have a problem I must solve and could not find an answer after a couple weeks of research, so here I am. I have created a custom Table Cell Renderer than extends DefaultTreeCellRenderer. The mission of this renderer is to set the branch icons depending on conditional statements. There are 3 conditions, and each one should render a different icon. These conditions must be tested against all branches in the tree. This means that using something like setOpenIcon() and setClosedIcon() will not work since it seems as though these methods set all branches to a specific icon (I could be wrong about that though). Below is the code for my custom. I made comments so it is easier to understand what I want to happen and what is not happening.
/**Custom Cell Render that will set the icons for the tree branches and the leafs*/
private TreeIconCellRenderer extends DefaultTreeCellRenderer{
public Component.getTreeCellRendererComponent(JTree tree, Object value,boolean selected,boolean expanded, boolean leaf, boolean row, boolean hasFocus){
//Get defaults in case there is no need to renderer
[Code] ...
What I really need to know is why the renderer is not differentiating between the leaves and branches. The logging statements I have added confirm that the branch block of code does not execute.
Why the label wont show the file. The file is located within the project.

View Replies View RelatedI'm working on making a game in JAVA. To be brief, the game is on a 6x6 matrix called "blocks[][]". The game has two players and the objective is to capture the enemies pieces by moving your piece onto there's. The players do this by moving one piece per turn either forward/backward (Vertically) or right/left (horizontal) movements. Essentially checkers without jumps.I'm not very far into the development process here. So far I have the game board created and the pieces load by clicking the "Start" button (handled by the refresh function). However I'm having a few problems... Namely moving the pieces effectively at the moment.
Right now there's a lot to do:
(1) - Implement a turn system,
(2) - Only allow a player to click their pieces (I've a validation function already in place to only permit valid moves [horizontal/vertical only]),
(3) - getting the pieces to actually "move" what I mean by this is a player selects the piece they want to move, then they select the spot they want to move to and the icon I have placed on the button is supposed to be added to the new square and the icon for its previous position is to be made null.
Please see the "actionPerformed" section to see exactly what I'm trying to do and hopefully as well see what I'm missing as to why it is not working at the moment... Also see under the Refresh function where I commented out the for loops to add the pieces. I did this because it was resulting in an ArrayOutofBounds error so I just wrote each spot out manually where I wanted them to start.

JFrame frame = new JFrame();

so the dialog has its owner frame, which is neccessary but i want the dialog has another icon ,or remove the icon on the dialog how may i do ?
I recently made a game. But, I want to package it and give it to my friends. I know that I can create a jar of it and add the images to the folder, but what I would absolutely love is for it to just be a picture with the game name and click to run. The second thing is to replace that java icon to an icon of my preference, which I have been told numerous times to do with
frame.setIconImage(Image image)
which does not work for me.
how do you get from launching some java code in eclipse to launching a java program from your desktop.Does one somehow wrap the code in C+ to make it a .exe? take for example Mine-Craft.Its build in Java however launches as a .exe.
View Replies View RelatedAny documentation that deals with assigining an icon to your application? I have tried the:
"stage.getIcons().add(new Image(this.getClass().getResourceAsStream("myicon.png")));"
Code as suggested on the web. It looks like this changes the icon in the window decoration only, which doesn't actually show on my Ubuntu desktop with Unity. What I really want is a custom icon for when I alt-tab through open applications. Currently it shows the default grey question mark. How do I assign an icon to the application.
