I create some panel with a lot of components as images text ... . Now I have one problem. Customers tell me that panel is too small. Is there some option to enlarge this whole panel or I have to enlarged components one by one ?
UPDATE:
from this:
to this:
everything depends of used LayoutManager,
Is there some option to enlarge this whole panel or I have to enlarged
components one by one
-> no, basically this is reason why LayoutManager exists there, most of them there are created especially for this reasons, GridLayout, GridBagLayout, BoxLayout (maybe without glue), BorderLayout and todays MigLayout are best way how to do it
it depends, if you have a GridLayout or some Layout witch set all the components with some order, for example, all the components at the same distance or all the components like a Matrix, if you enlarge the panel, all the components will enlarge with it. If not, you have to enlarge by hand.

I have used borderlayout to specify where the content of my java GUI shall be placed, I have then chosen to place it on EAST and then made two boxlayouts to show two columns of buttons. I now have to place something underneath it and not beside it. How would you suggest or advice me to do so, using any layout but preferably boxlayout and not absolute layout(null). Thanks in advance.

The arrow points to the place I want another JPanel to be.
You could...
Wrap both of the button panels in a JPanel
Whatever component goes at the arrow, wrap in a JPanel with GrigbagLayout (just to center it).
Create another JPanel with BorderLayout that will hold the above panels. Use CENTER and SOUTH.
Give an EmptyBorder to the SOUTH panel, only specifying the top region and space it accordingly.
Really there are many ways to accomplish this. The key though is to nest JPanels and make use of the different layout managers with each, use EmptyBorders or stuts for empty spaces til you get your desired effect. The possibilities are endless. I don't think there's one right answer. Since we don't have a runnable example, I say just try the above, and mix and match will you get what you want.
I would appreciate, If anyone here is kind enough to recommend me what are the layout managers to choose
and how to separate the attached GUI into Jpanels.
Thanks so much in advance.
What I have tried so far:
Jframe - BorderLayout
Map (the grid and clear button from another class extending jpanel) - so I have put it in jframe.CENTER
the buttons to the right: jframe.EAST
I put them in a jpanel in a gridlayout (but I cannot get the spacing between the components)
buttons at the bottom: jframe.SOUTH
I put them in a jpanel in a gridlayout (but I cannot get the spacing between the components)
When trying to determine what layout(s) you should use, you should start by trying to determine areas of responsibility...
For example...
Based on your needs, I might start with a GridBagLayout. This might seem complex, but if you break the UI down into seperate components, focusing on their individual needs, it should become simpler...
For the panel on the left...
I would be temptered to use a GridBagLayout, simply because it allows the components to use there preferred sizes, but still allows you to set up a grid like pattern...
For the arrow buttons...
This becomes a little more complicated, but I would use a GridLayout(2, 3) (2 rows, 3 columns). This will require to add a filler panel at the first and third position along the top row, but still maintain the buttons at a equal size...
For this panel...
I would be tempted to either use a GridBagLayout, because it will allow you to span the rows or even split it again into two separate panels, with the controls on the left in a GridLayout(2, 1) and the control on the right in something like a BorderLayout as required...
For "progress" panel...
I would be tempted to use...GridBagLayout. Mostly because it would allow you to provide more weight to the progress bars then the labels.
For the main panel...
I would probably be tempted to either use a BorderLayout, with the Clear Map on another panel of it's own, allowing it maintain it's preferred size, in the NORTH position and the map panel in the CENTER or even a GridBagLayout depending on what the invidual components are...
I'm posting this question because I'm new to programming at the present time and I have a pet peeve that when I create the app I don't want the objects to go across the entire window.
I use GridLayout the most often and I was wondering if there was a way to make components such as a JTextField or JTextArea NOT span the entire window, leave a little space on both ends?
You can add a component to a JPanel, which uses a FlowLayout by default and all components are displayed at their preferred sizes. Then add the panel to the layout using the GridLayout. The panel will increase in size but the components on the panel will stay at their preferred size.
I am making a game, and I am wondering if there is any way that you can resize the frame so that everything inside will also resize with it too?
That is the job of the LayoutManager. Choose your LayoutManager carfully so that it arranges your components properly. For example, if you use a BorderLayout, the center component will be stretched to take all the space not occupied by NORTH-SOUTH or WEST-EAST.
You need to choose the right LayoutManager for you. You can have layouts within layouts by putting JPanels within JPanels.
If you find the Java Swing library annoying to work with like that, then I suggest using Netbeans IDE where you can design visually how your GUI will look like.
On my Java Swing application I have two components. On the left side is a navigation (JList) and on the right side is a JTable. I would like to leave the possibility to increase the size of the window, without increasing the size of both components.
The proportion of 50/50 is kept, through ought the whole sizing. I use GridLayout. Is this behavior rooted into the LayoutManager or is a property which has to be set?
GridbagLayout will allow you to achieve this. However, have you also considered using a JSplitPane where the left-hand side contains your navigation panel and the right hand side contains the table? You could configure it so that all additional space is allocated to the right hand side by calling setResizeWeight(0.0). However, you still retain the flexibility of allowing the user to manually resize the navigation area if required. You also have the option to hide your navigation panel completely by calling setOneTouchExpandable(true) on the split pane.
From what I know the GridLayout manager resizes all cells to the same size. Knowing this you might use it anyway just add the component you want to stay unchanged to a panel and then add this panel to a cell instead.
Or use a different layout manager mine favourite is TableLayout, where you can set which columns/rows should fill the empty space where the rest will stay in their preferred size.
Good luck, Boro
Suggestion: Don't us GridLayout. Instead use other layouts such Borderlayout or GridBagLayout or a combination of layouts. For instance if you used BorderLayout, you could but the JTable BorderLayout.CENTER and the JList in one of the other positions. Or if you use GridBagLayout, then by setting your GridBagConstraint weightx and weighty values correctly and the fill values (only you know what you currently desire), would allow selective enlargement of the components added to the container.
