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.

public static void showUI() {
int bedCount = getBedCount();
bedCount = bedCount - 5;
Toolkit tk = Toolkit.getDefaultToolkit();
int xSize = ((int) tk.getScreenSize().getWidth());
int ySize = ((int) tk.getScreenSize().getHeight());
ImageIcon maleBed = new ImageIcon("Images/Male.png");

c.gridx = 0;
c.gridy = 0;
bedsPane.add(bedLabel2, c);
}
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 :
package Main;

public class dummyGUI {
private static JPanel infopane, bedsPane, logopane, mainPanel;

}

int bedCount = 7; // getBedCount();
bedCount = bedCount - 5;

int ySize = ((int) tk.getScreenSize().getHeight());

}
The part here
gbl_bedsPane.columnWidths = new int[] { 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 };

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);

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"

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..
I am designing a window with GridBagLayout but when I run it the components of the window are quite big when I have a ScrollPane. When I don't have scroll and window is smaller the components overlap.

And the result is:
Overlapping components
What can I do to stop the components overlapping?
How can I make the components smaller?
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");
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

//vamos verificar se n jah existem extensoes no arquivo .txt que podemos usar
this.verificarSeJaExistemExtensoesNoTxtParaJaPovoarAGuiComEstasExtensoes();
}
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 ^^

The default layout for a JFrame is a BorderLayout.
If you want to use a GridBagLayout then you need to set the layout of the content pane to use a GridBagLayout.
I suggest you read the section from the Swing turial on How to Use GridBagLayout for more explanation and working examples.
If you want to use a GridLayout, then you also need to set the layout manager of the content pane to a GridLayout and you don't use any constraints. Again, read the tutorial for examples.

This doesn't answer your question directly. But really don't use GridBagLayout.. its a crazy layoutmanager. Look at the amount of code you need to write to layout your components. IMO, thats the reason why many people moved away from not writing Swing application.
Instead use the jgoodies form layout. Here it is: http://www.jgoodies.com/freeware/forms/
If you haven't heard about it.. its a very simple layout manager. You can specify the column and row specs as simple strings. You can use existing PanelBuider or FormBuilder in the library or make one of your own. I have made one here:
http://code.google.com/p/swingobjects/source/browse/SwingObjects/src/org/aesthete/swingobjects/view/SwingObjFormBuilder.java
