Set Icon Of File Depending On What Is In It - Like PNG
Feb 15, 2014
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?
but I want the objects to be made inside a loop and named after how many times the loop have been gone through so I tried
Pipe pipe(numberOfTimes) = new Pipe
where numberOfTimes was a variable counting the loops. This is not working.I need the naming to be pipe1, pipe2, pipe3 etc depending on how many times the loop have been pased
Scanner keyboard = new Scanner (System.in); String morePipes = ("yes"); int dimRor; int numberOfPipes = -1;
I am stuck trying to build a relatively "simple" GUI. The GUI should have one JComboBox that allows the user to pick from one of three locations. Then based on their choice, another JComboBox should be generated with another set of choices. The key is that the second ComboBox should have different choices depending on the selection made in the first one. So, in theory, the logic should be something like:
//create new JComboBox array of strings "locations" //create new JComboBox array of strings "costToTravelThere" //if user picks location 1 from the first ComboBox then add the second ComboBox with options specific to that first location else if user picks location 2 from first ComboBox then add the second ComboBox with options specific to that second locatoin
I understand how to do the basic stuff, like create the JFrame and the actual panels and ComboBoxes, etc. What I don't understand is how to implement the second ComboBox dependent on the first one. I'm not very experience with Listeners and such, and I'm sure that's a big part of this.
I'm taking a class in object oriented programming and we have a task to write a method that returns positive, negative or zero depending on the sum of two variables.
I've had a go at it and i've got to a certain point but i'm struggling to get past this on error - return outside method.
public class Test { public int sumArgs; public int arg1; public int arg2;
I developed a swing application using group layout. It resizes when I resize the frame but when I change the screen resolution or when I run the application in a laptop which has small sized screen, the components over lap each other. I need my application to fit according to the screen resolution
The code is as follows
private void initComponents() { jComboBox1 = new javax.swing.JComboBox(); jButton1 = new javax.swing.JButton(); jButton2 = new javax.swing.JButton(); jLabel1 = new javax.swing.JLabel(); jLabel2 = new javax.swing.JLabel(); jLabel3 = new javax.swing.JLabel();
[Code]...
According to the list item selected, an internal frame will appear in the desktop pane. I use group layout for that internal frame too.
The program needs to print an isosceles triangle depending on variables Height, BorderSymbol and Interior symbol, how to do that. Here is what i did so far :
{ int height = 5; int i = 0; int count = 0; String line = "";
[code]....
and the output is a blanc page nothing on the screen only spaces...
I am creating a login form for my project and it works great,the issue is that i want to open up different forms dependent on the username and password that i enter.for example if i enter a password 'manager' then it should open the manager page,or 'employee' should open the employee page.
I'm thinking that it is just a case of creating another sql query but i have tried and i cannot see the solution,i can open the employee page by default but that is not what i am trying to achieve. I am using an sqlite database which holds the username and password.
Here is my code
private void btn_LoginActionPerformed(java.awt.event.ActionEvent evt) { // code to login to the back office system String sql =" select username,password from Employee where username =? AND password =?";//sql query try{ pst =conn.prepareStatement(sql);
This is a part of my program. When the user enters "Exam Schedule" in the JtextField and clicks the add button I want the link to change to a link that opens a local pdf file. And if the user enters "Academic Calendar" the Jlabel will be set to another link. So far this works fine but the problem is that if you erase the textfield and enter another value the link of the previous value will still be there.
public void actionPerformed (ActionEvent e){ if (e.getSource ==add) { if (text.getText().equalsIgnoreCase("Exam Schedule")){ link1.setText(text.getText()); link1.setCursor(Cursor.getPredefinedCursor(Cursor.HAND_CURSOR));

I need creating a code that will create random addition or subtraction from 0-500 depending on their grade level. I know how to create a random for the math and subtraction. I just dont know how to get it to change depending on their grade level. Example I need it to ask their name, grade level, addition or subtraction then five addition or subtraction questions depending on what they chose.
I'm trying to get the program to roll a four sided die between 100 and 1000 times, depending on your input, and then displaying the answer.
public class Lab08 { public static void main(String[] args) { int v1 =0, v2 = 0, v3 = 0, v4 = 0; int n; char response; System.out.print("Enter number of rolls (100-1000): ");
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:
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.
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.
how to display a jpg image on a through a Jlabel. I am sure it is a simple error but I am still new to GUI's. line 31 to 35 you can see the ImageIcon and file wrapped in the JLabel. I verified its in the correct location and file name, but usually fails (i thought) when it is not correct.
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.
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.
I'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.
I wrote this code which print a black image depends on the number of rows and columns you give it
public class BlackImg { private Mycolor[][] colorArr; //Mycolor is a class i wrote that represents colors. // no need for showing the class here. // so i created here an array of type Mycolor, for example: // { {(255,255,255), {(127,127,0)} }
[Code] .....
my problem is that my output comes good except the last line ,
Output: (0,0,0) (0,0,0) (0,0,0) (0,0,0) (0,0,0) (0,0,0) (0,0,0) (0,0,0) (0,0,0) (0,0,0) (0,0,0) (0,0,0) BlackImg@1db9742 //what is this line , why does it showing up ?
I am trying to use parallel arrays to store names and job titles, then display the name/job title combo depending on which is entered. I have always struggled with arrays, so I'm sure that's where my issue is, but I am not sure how to resolve this one. I tried to use the toString() method with the jobs to see if that would allow the job title to match to one of the titles listed, and I tried to not use the toString() method with the names to see if that would allow the name entered to match to one of the names listed in the array. Both options only display the "invalid" message no matter what I enter. What would be the best choice to use the arrays to properly display the information ....
import java.util.*; import javax.swing.*; import java.awt.*; import java.awt.event.*; public class JEmployeeTitle2 extends JApplet implements ActionListener { Container con = getContentPane();
