I have created a GridLayout for my GUI to show 6 rows and 4 columns. I am trying to get the two buttons I have "Calculate" and "Exit" to show in the 6th row. I only have two pane.add of four for row 5 (which is the weight label and textfield). I'm just trying to get the calculate and exit buttons to be on their own row. I tried to do pane.add(); to fill the gap and couldn't get it to work. What am I missing so that I can get the buttons on their own row?
basically I have
pane.setLayout(new GridLayout(6, 4));
pane.add(score1L);
pane.add(score1TF);
pane.add(weight1L);
pane.add(weight1TF);
pane.add(score2L);
pane.add(score2TF);
pane.add(weight2L);
pane.add(weight2TF);
pane.add(score3L);
pane.add(score3TF);
pane.add(weight3L);
pane.add(weight3TF);
pane.add(score4L);
pane.add(score4TF);
pane.add(weight4L);
pane.add(weight4TF);
pane.add(weightAvgL);
pane.add(weightAvgTF);
pane.add(calculateB);
pane.add(exitB);
Possible options:
Add empty JLabels to fill in any gaps.
Use mixed layouts -- nest JPanels, each using its own layout and add components to them. For example, the overall JPanel could use BorderLayout. The textfields/labels could be in a GridLayout or GridBagLayout using JPanel added BorderLayout.CENTER to the main JPanel. The JButtons could be held in their own GridLayout using JPanel that is then added BorderLayout.PAGE_END to the main JPanel.
Use a layout manager that allows for more complex layouts such as a GridBagLayout, or better perhaps, a 3rd party layout manager such as MigLayout.
Perhaps the best of all --use a JTable to hold your data grid, add it to a JScrollPane, and then place your buttons below the JScrollPane.

I am trying to design a simple gui interface. The frame consists of a main panel which contains another four panels "Staff Details", "Job Details" "Photo" and buttons. The output is as follows:
I used gridLayout for all the panels except for the "buttons panel" which has borderLayout.
Now I want to reduce the height of the bottom two panels so it won't have the extra space. How do I do that?
Here is the code for the "photo" panel and "button" panel. Both panels now have flow layout.
photoPanel.setPreferredSize(new Dimension(300,70));
photoPanel.add(browsebx);
photoPanel.add(browseBtn);
btnPanel.setPreferredSize(new Dimension(300,70));
btnPanel.add(addBtn);
btnPanel.add(editBtn);
btnPanel.add(deleteBtn);
btnPanel.add(cancelBtn);
Your main panel is using a GridLayout, which means all four panels will be the exact same size. Don't use a GridLayout.
Instead maybe you can use a GridBagLayout. This allows your to add each panel to a specific grid, but each panel will maintain its preferred size as determines by the layout manager used on each of the individual panels.
Read the section from the Swing tutorial on How to Use GridBagLayout for more information and examples.
Remember each of the 4 child panels can use a different layout manager if desired. For example you would probably want to use a FlowLayout for the buttons panel.
you can use this.
jPanel.setPreferredSize(new Dimension(x, y));
jPanel.setMaximumSize(new Dimension(x, y));
jPanel.setMinimumSize(new Dimension(x, y));
I'm working with a few people to design a game for a project in class. While making the main menu GUI, I searched all over for some way to get the design the way I wanted (here), but I couldn't figure it out. CardLayout, BoxLayout, BorderLayout, GridLayout, none of those have helped in what I'm trying to do, at least not the way I was implementing each layout. Is there some other layout that could help me with aligning the title text and 4 buttons to the left (horizontally) and aligned with each other vertically. Is it possible to use GridLayout with maybe 5 rows and 3 columns and just fill the 2nd and 3rd columns with nothing? I also want there to be sufficient padding between each object and from the bounds of the window.
This is what I've got so far, but this spreads the width of all the buttons across the entire window:
JLabel title = new JLabel("Inkball", JLabel.LEFT);
JPanel panel = new JPanel();
panel.setLayout(new GridLayout(5, 3, 0, 25));
panel.add(title);
panel.add(playNow);
panel.add(highScore);
panel.add(rules);
panel.add(exitGame);
Container c = this.getContentPane();
c.add(panel, BorderLayout.CENTER);
Start with a BorderLayout.
To this, add a JPanel that uses either a GridLayout or GridBagLayout, to the BorderLayout.WEST position of the parent container, this panel will be used to layout the options on the right
Add a JPanel with a CardLayout to the BorderLayout.CENTER position of the first container. This will will allow you to switch between views based on the selection of the user.
You will need to have the ability to obtain notification about user selection from the "menu pane" and update the "view pane". You simply use a ActionListener, registered to the "menu pane", which acts a proxy for the buttons actions and provide information about what the action menus via the actionCommand property of the JButtons and ActionEvent

So I was trying to google how to set a default size to JButtons so that they don't grow as the JFrame is resized. I didn't see a setDefaultSize method but the closest one I could find that does a similar job is setMaximumSize(). However, it doesn't seem to work in my situation and I'm guessing it's because I'm using Grid Layout for positioning my buttons in the frame, here's a small piece of my code:
rightPanel.add(ButtonA);
rightPanel.add(ButtonB);
rightPanel.add(ButtonC);
outerPanel.add(leftPanel);
outerPanel.add(rightPanel);
getContentPane().add(outerPanel);
Here's a picture of what happens:
I would also like to have my buttons in the middle of the right panel when I'm resizing (just like they are now but a lot smaller). Any idea of how I can fix this? I'm assuming that I have to use another layout or something.
Thanks
EDIT: I modified my code to use BoxLayout but it does not seem to put the buttons in the middle. The X Alignment is working but Y Alignment is not doing anything:
ButtonA.setAlignmentX(CENTER_ALIGNMENT);
ButtonA.setAlignmentY(CENTER_ALIGNMENT);
ButtonB.setAlignmentX(CENTER_ALIGNMENT);
ButtonB.setAlignmentY(CENTER_ALIGNMENT);
ButtonC.setAlignmentX(CENTER_ALIGNMENT);
ButtonC.setAlignmentY(CENTER_ALIGNMENT);
JPanel rightPanel = new JPanel();
rightPanel.setLayout(new BoxLayout(rightPanel, BoxLayout.Y_AXIS));
rightPanel.add(ButtonA);
rightPanel.add(ButtonB);
rightPanel.add(ButtonC);
outerPanel.add(leftPanel);
outerPanel.add(rightPanel);
getContentPane().add(outerPanel);
EDIT2: Fixed with vertical glue.
A GridLayout will always resize the components to fill the space available.
Try using a vertical BoxLayoutinstead. See the section from the Swing tutorial on How to Use Box Layout for more information and examples.
Encapsulate each JButton in a JPanel with a FlowLayout, and then add those FlowLayout JPanels to the rightPanel instead of the JButtons themselves. This will allow you to keep your evenly spaced buttons, but won't make them expand to take up the entire space that the parent container has available.
If you don't want them evenly spaced, but to be three consecutive buttons one after another top down, you can make the right panel have a BorderLayout, add a sub panel to the north area of the BorderLayout with the original GridLayout that the right panel had, and then add those FlowLayout panels containing the JButtons.
Can i combine Java layouts in same JPanel. I'm stuck with with placing my components on JPanel. It shoudl be like this: JLabel, JButton, JButton , JLabel and new line and same. I used BorderLayout but it wont go to the next row, keep adding components to same row and I need a new row. Ideal sit combined with cardlayout or some other good solution.
EDIT: Solved with GridLayout (0,4) It will do the job till i learn to use GridBaglayout. Thank you for trying to help me.
Yes you can combine layouts.
Using a JPanel you are able to embed other JPanels:
JPanel back = new JPanel(new BorderLayout());
JPanel rows = new JPabel(new GridLayout(3,3));
back.add(rows, BorderLayout.CENTER);
Without seeing your code though it's difficult to know exactly what you are trying to achieve!
Yes you can combine java layouts.
A common pattern I use is BorderLayout first on a frame. The central component expands out, while the other components shrink in. Inside these panels I might have a Flowlayout to show buttons evenly spaced horizontally on top.
Another common approach for forms is using a Gridbaglayout, then adding all the form elements at gridX and gridY positions. I then later can stretch and teak these cells using other constraints in the Gridbaglayout repetoire.
Can you add a screenshot so that we can see what you want to do?
My current problem is that I have a JFrame with a 2x2 GridLayout. And inside one of the squares, I have a JPanel that is to display a grid. I am having a field day with the java swing library... take a look
Image
Java is automatically expanding each JLabel to fit the screen. I want it to just be those blue squares (water) and the black border and not that gray space. Is there a way I can just set the size of that JPanel permanently so that I don't have to go through changing the size of the JFrame a million times before I get the exact dimension so that the gray space disappears?
I also would like to set the size of those buttons so they are not so huge (BorderLayout is being used for the buttons and TextField)
GridBagLayout is what you really want to use. The GridLayout will force the same size for each component in the layout no matter what size constraints you put on them. GridBagLayout is a lot more powerful and a lot more complicated. Study up on the API page for it. Using GridBagLayout, the components won't fill the whole grid space if you don't want them to and can even stay the size that you ask it to be. To keep a component's size from changing, I would set all three available size constraints:
water.setPreferredSize(new Dimension(20, 20));
water.setMinimumSize(new Dimension(20, 20));
water.setMaximumSize(new Dimension(20, 20));
For your buttons, I would definitely use an inner panel as Bryan mentions. You could use either a GridLayout like he suggests or a FlowLayout if you don't want all the buttons to be the same size. Add all your buttons to that inner panel instead of the main one.
If you want the two checkerboards to stay the same size, then you'll need to have them each contained in their own JPanel. Set each of those parent JPanel's to have a layout type of GridBagLayout. Set the preferedSize for each checkerboard component and then add them to their respective containers. GridBagLayout should by default lay each board out in the center of the parent JPanel. So as the window is resized, the JPanel parent area will get larger or smaller, but the checkerboard components inside will remain the same size.
Alternatively, you could have your blue squares scale to the right size as the window is resized by having each checkboard square be a JPanel with a BorderLayout layout manager and adding the JLabel (with a blue background color) to its BorderLayout.CENTER location.
As for your buttons, try something like this:
JPanel theButtonPanel = new JPanel(new BorderLayout());
JButton button1 = new JButton("Fire");
JButton button2 = new JButton("Pass");
JButton button3 = new JButton("Forfiet");
JPanel innerButtonContainer = new JPanel(new Grid(1, 3, 8, 8));
innerButtonContainer.add(button1);
innerButtonContainer.add(button2);
innerButtonContainer.add(button3);
theButtonPanel.add(innterButtonContainer);
Lastly, consider using a design tool for your Swing user interface. Netbeans has an excellent UI designer built into it. Download Netbeans here.
If you can setResizeable( false ) on the top level frame you can then set your layout manager to null and hard code each location and size via setBounds. This is how I would do it (contingent on resizing of course).
I have had success solving problems like these using TableLayout which is a third party layout manager. You will need to download it and read the tutorial but the key would be to set the justification to CENTER when adding the JButtons to their positions in the layout.
