I can run .jar files through cmd, but I cannot double click them [closed]
(7 answers)
Closed 2 years ago.
My MineSweeper project works perfectly in the IDE, but it doesn't work when I export is as "Runnable Jar File" in Eclipse and executing it afterwards.
My MANIFEST.MF
I also tried to navigate via cmd there and do javac Minesweeper.jar.
Console says it cant find the command "javac".
If i cd into my folder and just do java Minesweeper.jar it says: "Cant find or load Mainclass Minesweeper.jar"
This is my code in which the main method is located:

The way to run a runnable jar is with the -jar parameter, e.g. java -jar Minesweeper.jar . Otherwise it assumes you mean a class name on the CLASSPATH environment variable, which you shouldn't rely on.
Figured it out i had to change stuff in my registry
I can run .jar files through cmd, but I cannot double click them
sry for asking this another time when there is an answer already..
putting a JPanel in a JFrame: setContentPane() and add() both seem to work. Is there any technical difference?
One example from web has the following. Changing frame.setContentPane(panel) to frame.add(panel) seems to produce the same behavior.
//file: Calculator.java
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class Calculator extends JPanel implements ActionListener {
GridBagConstraints gbc = new GridBagConstraints();
JTextField theDisplay = new JTextField();
public Calculator() {
gbc.weightx = 1.0; gbc.weighty = 1.0;
gbc.fill = GridBagConstraints.BOTH;
ContainerListener listener = new ContainerAdapter() {
public void componentAdded(ContainerEvent e) {
Component comp = e.getChild();
if (comp instanceof JButton)
((JButton)comp).addActionListener(Calculator.this);
}
};
addContainerListener(listener);
gbc.gridwidth = 4;
addGB(this, theDisplay, 0, 0);
// make the top row
JPanel topRow = new JPanel();
topRow.addContainerListener(listener);
gbc.gridwidth = 1;
gbc.weightx = 1.0;
addGB(topRow, new JButton("C"), 0, 0);
gbc.weightx = 0.33;
addGB(topRow, new JButton("%"), 1, 0);
gbc.weightx = 1.0;
addGB(topRow, new JButton("+"), 2, 0 );
gbc.gridwidth = 4;
addGB(this, topRow, 0, 1);
gbc.weightx = 1.0; gbc.gridwidth = 1;
// make the digits
for(int j=0; j<3; j++)
for(int i=0; i<3; i++)
addGB(this, new JButton("" + ((2-j)*3+i+1) ), i, j+2);
// -, x, and divide
addGB(this, new JButton("-"), 3, 2);
addGB(this, new JButton("x"), 3, 3);
addGB(this, new JButton("\u00F7"), 3, 4);
// make the bottom row
JPanel bottomRow = new JPanel();
bottomRow.addContainerListener(listener);
gbc.weightx = 1.0;
addGB(bottomRow, new JButton("0"), 0, 0);
gbc.weightx = 0.33;
addGB(bottomRow, new JButton("."), 1, 0);
gbc.weightx = 1.0;
addGB(bottomRow, new JButton("="), 2, 0);
gbc.gridwidth = 4;
addGB(this, bottomRow, 0, 5);
}
void addGB(Container cont, Component comp, int x, int y) {
if ((cont.getLayout() instanceof GridBagLayout) == false)
cont.setLayout(new GridBagLayout());
gbc.gridx = x; gbc.gridy = y;
cont.add(comp, gbc);
}
public void actionPerformed(ActionEvent e) {
if (e.getActionCommand().equals("C"))
theDisplay.setText("");
else
theDisplay.setText(theDisplay.getText()

}

}
Another has the following. Changing frame.add(panel) to frame.setContentPane(panel) seems to produce the same behavior.

The content pane of the frame is a JPanel.
So if you use frame.add( another panel ), then you have a structure like:
- JFrame
- content pane
- another panel
If you use frame setContentPane( another panel ) you have:
- JFrame
- another panel
See the section from the Swing tutorial on Adding Components to the Content Pane.
I have been chasing this bug for awhile and can't seem to figure it out. I have a small GUI with a list of labels and text fields. In between the rows that have a label + text field, there is an empty row that contains a JLabel to populate with an error message as necessary. The issue is, when this error message populates, the text fields above them are compressed for some reason and after a few hours of trying different things, I can't seem to pinpoint why. It also seems like all the labels/text areas compress compared to each other slightly as well. Can anyone point out the issue?
I have tried giving each element more space as well in the panel gridbaglayout. That doesn't seem to change the end result.
If looking at the code, the elements are on the 'continuousTransferPanel" Also the "singleTransferPanel" has the same issue with only 2 rows.

Resulting GUI:
Since the problem is with your JTextField's Border, and since you can't reset the default border outright without running into problems, one solution is to create a CompoundBorder for your JTextField, the outer border a LineBorder that uses the same color as the JPanel's background color and the inner border being JTextField's default border. Then in your action listener, simply create a new compound border, one that uses a Color.RED outer border.
So when creating my JTextFields in the example below, I also create a CompoundBorder, giving it an outerBorder and innerBorder like so:
// create JTextField with TF_COLS int column count value
JTextField textField = new JTextField(TF_COLS);
// get the JTextField's default border and make it our inner border
Border innerBorder = textField.getBorder();
// create an outer LineBorder that uses the JPanel's background color
Border outerBorder = BorderFactory.createLineBorder(BACKGROUND);
// create the compound border with these two borders
CompoundBorder myBorder = BorderFactory.createCompoundBorder(outerBorder, innerBorder);
// and set the JTextField's border with it
textField.setBorder(myBorder);
Then in the JButton's ActionListener, get the JTextField's current border, our compound border, and change the outer border's line color. Simple:
// loop through all the JLabel texts
for (int i = 0; i < LABELS.length; i++) {
String text = LABELS[i]; // get the array item
// use it to get the JTextField associated with this String
JTextField textField = labelFieldMap.get(text);
// same for the error JLabel
JLabel errorLabel = errorLabelMap.get(text);
// get our current JTextField's border which is a compound border
CompoundBorder myBorder = (CompoundBorder) textField.getBorder();
// the insideBorder, the original JTextField's border, will be unchanged
Border insideBorder = myBorder.getInsideBorder();
// if the text field is empty (and not the last jtext field)
if (i < LABELS.length - 1 && textField.getText().trim().isEmpty()) {
errorLabel.setText(ERROR_MESSAGE); // set the error JLabel
// set txt field's color if we want
textField.setBackground(ERROR_BG_COLOR);
// okToTransfer = false;
// create a compound border, the outer border now a line border, RED
Border outsideBorder = BorderFactory.createLineBorder(Color.RED);
CompoundBorder newBorder = BorderFactory.createCompoundBorder(outsideBorder, insideBorder);
// set the JTextField's border to this one
textField.setBorder(newBorder);
} else {
// else all OK
errorLabel.setText(" ");
textField.setBackground(Color.WHITE);
// set the JTextField's border back to our original compound border
Border outsideBorder = BorderFactory.createLineBorder(BACKGROUND);
CompoundBorder newBorder = BorderFactory.createCompoundBorder(outsideBorder,
insideBorder);
textField.setBorder(newBorder);
}
System.out.println(text + " " + textField.getText());

Can a setText() operation of a JLabel be called outside a JPanel ou the class that created it? Because i have to change my JLabel on a Singleton i created. When i use the setText() function, the text attribute of the JLabel is changed(i can see it from debug), but visually it is still the same old text.
But when i change the text from inside the JPanel that created the JLabel, it works... But i don't want this. I have to make setText() work outside of a JPanel. I am calling it from a Singleton which is created inside the JPanel construction.
The class that contains my JLabel is TelaPrincipal. And on it´s constructor, i change the text of the JLabel via a "setText()" and it workds just fine:
public TelaPrincipal() {
setTitle("codefont2file");

//vamos verificar se n jah existem extensoes no arquivo .txt que podemos usar

}
But when i try to change it via my Singleton on this method:
public void inicializarBarraDeProgresso(int valorMaximo, String textoBarra)
{
if(barraDeProgresso != null)
{
barraDeProgresso.setVisible(true);
barraDeProgresso.setStringPainted(true);
barraDeProgresso.setValue(0);
this.barraDeProgresso.setMaximum(valorMaximo);
this.barraDeProgresso.setMinimum(0);
this.textoBarraDeProgresso.setVisible(true);
this.textoBarraDeProgresso.setText(textoBarra);
}
}
Which is called inside many classes(TelaPrincipal is one of them, but there are a lot of other classes), the text stays the same: "oi meu nome é andrews"
I have also tried myJLabel.update(myJLabel.getGraphics()); after the setText(), but it bugs by text(it´s like it creates a loop which puts a lot of text over each other).
This post is the real lifesaver:
Why isn't setText updating the JLabel?
Basically, all you have to do is:
label.paintImmediately(label.getVisibleRect());
Right after the settext().
Java swing is confusing and annoying. I really do like working with android better ^^
I'm trying to use multiple layouts (Border and Gridbag) to make a standalone visual application that shows the status of recovery rooms. I want my company logo to be in the top left corner. Directly to the right of the logo I want to have information shown in text format such as available beds, how many total occupants, ect...
Below that I am using the Grid bag layout to place bed icons as well as room numbers. There will be a lot more icons later on, I've only got two added at the moment just to show where they will start on the page.
I've provided an image of what it currently looks like with my source code.
TLDR: I need to beds shown in the image to be in the upper left part of the screen about half an inch from the bottom of the sample logo.
I tried to add an image, but I don't have enough reputation. here is a link to it if you need to see.

Well for the blank around panels you probably need to set the insets
eg: c.insets = new Insets(0, 0, 0, 0);
I am not sure how you want to handle 2 layout but you can do the effect you want with simply GridBagLayout.
You can see my test code here :

The part here

gbl_bedsPane.rowHeights = new int[] { 1, 0, 0, 0, 0 };
gbl_bedsPane.rowWeights = new double[] { 0.0, 0.0, 0.0, 0.0, Double.MIN_VALUE };
is where you can tell the number of row and column. I did not set enough column that is why you see it appear on the right when you add more.
I also did a function like i said in the comment :
private static JLabel add_bed(String sex, int x, int y){
JLabel bed = null;
if (sex == "female"){
bed = new JLabel(femaleBed);
GridBagConstraints gbc_lfemalebed = new GridBagConstraints();
gbc_lfemalebed.insets = new Insets(0, 0, 0, 0);
gbc_lfemalebed.gridx = x;
gbc_lfemalebed.gridy = y;
bedsPane.add(lfemalebed, gbc_lfemalebed);
}else if (sex == "male"){
lmalebed = new JLabel(maleBed);
GridBagConstraints gbc_lmalebed = new GridBagConstraints();
gbc_lmalebed.insets = new Insets(0, 0, 0, 0);
gbc_lmalebed.gridx = x;
gbc_lmalebed.gridy = y;
bedsPane.add(lmalebed, gbc_lmalebed);
}
return bed;
}
Then i can just do
add_bed("female", 5 , 1);
