JTextArea & Gridbag layout - max size of control
Hello everyone:
I am currnetly using a JTextArea with the Gridbag layout. I want to limit the size of the JTextArea. Found an article when I did a "search" that says the size is actually controlled by the layout manager. Have tried setMaximunSize(), no luck. It appears the layout manager ignores this. The problem I am having is that I can set the size I want, however if the user types a lot of text in to the JTextArea, the control expands and over and "pushes" the controls below it down. How do I keep the layout manager from allowing this to happen?
Thanks in advance, Bart

Thanks in advance, Bart Do you wish to allow the user to enter as much text as he or she likes? If so, wrap the JTextArea in a JScrollPane and set the preferred size of the JScrollPange to the area you'd like the pane to consume. It'll listen, no doubt. :)

Thanks in advance, BartHave set the rows and columns as you suggested in the original code,and get the size I want initalially. The problem is that the JTextArea will increase past the size set so it "bleeds" downward. I looked in the Java book I have, and it says that the scrollbars for a JTextArea are provided automatically, however they do not appear when the user supplies more lines of text than there are rows. Instead the height of the control is enlarged and this in turn pushes the other controls on the pane down. Is this a mi-print in the book, ie the scroll bars are not automatically provide in a JTextArea?
Thanks,

can I set a pixel width size for the cell of a gridbag?
Set the minimum width and height as well as preferred width and height and let the layout manager take care of the size.
You can not set the absolute width and height because components under GridbagLayout do not have adjustable size. Their size is determinded by layout manager, and the only thing you can set is the layout constraints and minimum/maximum/preferred size. -
Data size bigger than max size for this type - DB Control
All,
We are using a Java Control to fetch and store data
- it fetches data from a webservice through a webservice control
- it stores data in to database using a database control (stores the data as BLOB)
Here currently we facing an error - weblogic.jws.control.ControlException: ControlException on control databaseManager[Data size bigger than max size for this type: 4516]
The data is definitely not overshooting the max capacity of BLOB which is 4 GB. Initially this process was overshooting the transaction time-out limit of 300 sec but currently this is well within the transaction time-out limit and error happens soon after the webservice returns the data.
a. Are there any known issues with using BLOB's with database controls ?
b. what are the options - if we face this error ?

Hi Sudeep. The problem is that WLW is trying to set the datum as a byte array
and the oracle driver won't take a byte array that big. Please check whether
WebLogic Workshop has any explicit instructions for BLOB data. Otherwise, do
contact official BEA support for your WebLogic WorkShop issue.
Joe

Controlling max size of a sparsebundle
Hi I want to put a max size onto a sparsebundle (for Time Machine purposes) and have tried
hdiutil resize -size 1500g /Volumes/WHPBak_1/WHP_Server_1001e52f1be50.sparsebundle
hdiutil: resize failed - error -5341
But as can see I get an error. Any ideas? thanksThere is a exact max size.
Before 8i, there is a limit around 5000 lines, more or less depending how compact your code is. After 8i, you can hit what ever long you can possibly write. -
Hey all,
I'm currently revamping an application I wrote for my company that I wrote with a GridLayout. It doesn't look bad, but it doesn't look as good as a standard windows application. I'd like to write it using a gridbag layout in order to make it look a little better but no where can I find a good idea of how to even use it... Javadocs on it seem kinda cryptic to me and I'd like a better visual example than just a bunch of buttons (which is what the tutorial gives). Anyone have any ideas where I can look?Here is a simple example of some of my code that uses the gridbag layout. (slightly modified so it will run by itself...). I added some comments on what some of the different settings do...

Gridbag Layout and Tabbed Panes
First off, I'm pretty new to Java, I started it around February as a school course, and it's been a pretty smooth ride. Recently, we started to code GUI, trying out different layouts and whatnot. I'm having a little trouble in this portion as our teacher did not really delve into it very much. My question concerns the GridBag layout within a panel of a tab (sorry if this is unclear, I'm talking about something that looks like this: http://www.codeproject.com/useritems/tabcontrol.asp). I don't know how to use GridBag constraints within a panel. What I used to do with GridBag was simply use some code that looked like (forgive me, this might not be very accurate): AddComponent button1(#, #, #, #) and define what each of those numbers meant later (first would be row, second would be column, third would be width, fourth would be height, for example). But now, with the tabs, each button, label, or any other control would be declared, then I would place a bunch of direct constraints after, like this:
JButton button1 = new JButton("1");
constraints.gridx = 0;
constraints.gridy = 0;
constraints.gridwidth = 1;
constraints.gridheight = 1;then add them into the panel like this:
panel1.add(button1, constraints);However, I have tried making the buttons on top of each other, and other patterns, but it would just place the buttons next to each other within the panel. How do I make it so that the constraints work? Or rather, if they do work, what kinda things might mess it up? I think the problem is that I dunno how to make the constraints specific to that one button.
Also, how do I make each panel a certain size instead of each panel being as small as possible to contain anything within it.
I'm sorry if this all sounds very vague, I'd be more than happy to give you any needed information. Also, I'm not asking any of you to do my homework, I just need a little clarification or an example. Just in case, here's the code I'm working on: http://hashasp.mine.nu/paster/?1376. Be aware that there are no comments or anything, it's very bare. Also, the form may be a bit messy because I'm pretty much reusing code that was given to me, just manipulating it in a different way. Thanks a lot in advanced for your time in reading this.* GridBag_Demo.java

Problem in Rolling to new a log file only when it exceeds max size (Log4net library)
Hello,
I am using log4net library to create log files.
My requirement is roll to a new log file with name appended with timestamp only when file size exceeds max size (file name ex: log_2014_12_11_12:34:45 etc).
My config is as follow
<appender name="LogFileAppender"
type="log4net.Appender.RollingFileAppender" >
<param name="File" value="logging\log.txt" />
<param name="AppendToFile" value="true" />
<rollingStyle value="Size" />
<maxSizeRollBackups value="2" />
<maximumFileSize value="2MB" />
<staticLogFileName value="true" />
<lockingModel type="log4net.Appender.FileAppender+MinimalLock" />
<layout type="log4net.Layout.PatternLayout">
<param name="ConversionPattern"
value="%-5p%d{yyyy-MM-dd hh:mm:ss} – %m%n" />
<conversionPattern
value="%newline%newline%date %newline%logger
[%property{NDC}] %newline>> %message%newline" />
</layout>
</appender>
Issue is date time is not appending to file name.
But if i set "Rolling style" as "Date or composite", file name gets appended with timestamp, but new file gets created before reaching max file size.(Because file gets created whenever date time changes, which i dont want) .
Please help me in solving this issue?
ThanksHello,
I'd ask the logfornet people: http://logging.apache.org/log4net/
Or search on codeproject - there may be some tutorials that would help you.

Gridbag layout problem on a tabbedpane
I am not sure whether we can do this or not but, I am trying to have a gridbag layout on a TabbedPane object.
I have a JFrame on which I am adding a TabbedPane object called "t" and on this TabbedPane I am adding a tab called "Insert" which is an object of class "Insert Data". Then, I add the TabbedPane t on the Container cp, which is inside the JFrame.
In the InsertData Class (a JPanel), I need to have the gridbag layout. With this gridbag layout object, I am trying to place different objects like buttons, at various places, on this JPanel. But nothing moves on this panel.
In short, please let me know how can I have a gridbag layout on a Tabbedpane.
The Main Class is as follows:
import java.awt.Color;
import java.awt.Container;
import java.awt.Dimension;
import java.awt.FlowLayout;
import javax.swing.JFrame;
import javax.swing.JTabbedPane;
import javax.swing.event.ChangeEvent;
import javax.swing.event.ChangeListener;
import java.awt.BorderLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
public class Main extends JFrame implements ActionListener, ChangeListener{
Main(){
setPreferredSize(new Dimension(1200,600));
Container cp = getContentPane();
JTabbedPane t = new JTabbedPane();
// insert
InsertData insertOptions = new InsertData();
t.addTab("Insert",insertOptions);
cp.add(t);
this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
pack();
setVisible(true);
@Override
public void actionPerformed(ActionEvent arg0) {
// TODO Auto-generated method stub
@Override
public void stateChanged(ChangeEvent arg0) {
// TODO Auto-generated method stub
public static void main(String args[]){
new Main();
}The InsertDataClass is:
import java.awt.BorderLayout;
import java.awt.Color;
import java.awt.Dimension;
import java.awt.FlowLayout;
import java.awt.GridBagConstraints;
import java.awt.GridBagLayout;
import java.awt.Insets;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JPanel;
public class InsertData extends JPanel{
InsertData(){
setPreferredSize(new Dimension(1200,600));
setBackground(Color.blue);
//setLayout(new GridBagLayout());
GridBagLayout gb = new GridBagLayout();
setLayout(gb);
GridBagConstraints c = new GridBagConstraints();
//c.insets = new Insets(2, 2, 2, 2);
//JPanel p1= new JPanel();
//p1.setPreferredSize(new Dimension(200,200));
JButton b1 = new JButton("here i am!!!");
//p1.add(b1);
//c.fill = GridBagConstraints.HORIZONTAL;
//c.anchor = GridBagConstraints.WEST;
c.gridx=0;
c.gridy=1;
add(b1,c);
}how can I have a gridbag layout on a Tabbedpane.Huh? You post an example with just one JButton and no weightx / weighty set and you expect others here to be able to see a problem with your layout?
Also, there's needless, unused code that is just clutter -- like the unimplemented ActionListener and ChaneListener. Recommended reading: [SSCCE (Short, Self Contained, Compilable and Executable, Example Program)|http://mindprod.com/jgloss/sscce.html].
Finally, I don't see any need whatsoever to extend JFrame and JPanel as you are not introducing any new behavior of either. Always favor composition over inheritance.
I plugged in some code I had used for someone else's GridBagLayout problems and this will show you that there's no difference in using GridBagLayout in a tabbed pane component or anywhere else.import java.awt.Dimension;

GridBag Layout - Auto Adjustment
I am using grid bag layout , I have the weightx to 1 and fill to horizontal. All I want is that my component occupy space horizontally.
I have set Preffered , Min and Max sizes.
There are empty space with a width of a 1 or 2 pixels occasionaly show up on left and right side of the grid.
The GridBad also adjusts the size of all the cells when I am just typing in cell.
regards,
IrfanIf you're using a GridBagLayout for a one-cell layout, you're working too hard: use BorderLayout instead.
If you have multiple cells, then make sure that only the cell you want to expand has weightx != 0. weightx is used to apportion excess space in the layout: if multiple columns are used and have non-zero weightx, then excess width will be assigned to each column by the ratio (column's weightx / total weightx for all columns).
You should avoid setting the different sizes of components in general and text components specifically. Use setColumns() instead, to give the component a hint. The text components use the columns value and their font to determine the width of the component (with some fudge factor involed as well).
If the layout manager is adjusting the size of the component, it is because the component is reporting a size change to its container. Without the columns value set for a text component, I believe that it is using its current contents to guess at the number of characters it is to allow room for, and as you type more characters, this computation changes (and thus changes the size). It might be being reported to the container as a size change or as a property change, but there is definitely something being reported to the parent on every keystroke. Look at the source for the various JText components: I may be mis-remembering, but I believe that they do take quite a bit more responsibility for their own sizes, and don't necessarily simply accept the size you give them as final. -
Gridbag layout continues to confound me...
I am having problems with the gridx and gridy constraints when trying to use gridbag layout. They seem to have no effect when I use them. The button always appears in the top left of the panel. Other constraints seem to work as expected.
For example: c2.fill = GridBagConstraints.BOTH; will fill up the entire panel with my button.
Any advice on what I am doing wrong this time?
Thanks

You could override this behavior by using GBL's four arrays as shown below.
However, in order to get the desired layout effect, using other layout manager, e.g. BoxLayout and/or Box, is much easier and flexible as camickr, a GBL hater, suggests.
Anyway, however, before using a complex API class as GBL, you shoud read the documentation closely.

Possible to set min/max size to a resizable Stage? If so, how?
Is it possible to set a minimum and maximum size to a resizable Stage? If so, how would this be done? Do I use some kind of onResize event handler or is there some other way?
Here is a sample code where I have a 500 x 500 px image in a 300 x 300 px scrollable scene that is in a resizable stage. Right now, I am able to resize the stage to any size, but I would like to limit the resizable minimum width and height to 100 x 100 px and limit the resizable maximum width and height to 600 x 600 px.
import javafx.stage.Stage;
import javafx.scene.Scene;
import javafx.scene.control.ScrollView;
import javafx.scene.control.ScrollBarPolicy;
import javafx.scene.image.ImageView;
import javafx.scene.image.Image;
var scene: Scene;
Stage {
resizable: true
scene: scene = Scene {
width: 300
height: 300
content: ScrollView {
hbarPolicy: ScrollBarPolicy.ALWAYS
vbarPolicy: ScrollBarPolicy.ALWAYS
width: bind scene.width
height: bind scene.height
node: ImageView {
image: Image { url: "{__DIR__}roses.jpg"}
}Hi, I don't understand how WidgetFX is going to allow me to set min/max size to a resizable Stage. After all, it is a desktop widget platform and I'm not trying to build a desktop widget. None of the demos I've tried use a decorated Stage with platform decorations that can be used to drag and resize the Stage.
I'm just trying to limit the min/max size of a resizable Stage. If you think WidgetFX will address my problem, I think a better solution is the JavaFX Stage Controller class I found available at http://code.google.com/p/memefx/. However, the JavaFX Stage Controller class still doesn't address the problem I have because it doesn't stop the user from dragging the Stage beyond the size restricted by the min/max height. It only reverts the Stage to the max size after the user already dragged and resized the Stage beyond the max resizable width/height. -
pdf file is too big (7MB). Need a pdf file with max size 4MB. How to minimize the size of a pdf file?
The other alternative is the Save As Other>Reduce File Size. The PDF Optimizer gives you more control. You might also use the audit feature in the PDF Optimizer to see where the size problem is coming from. You might find that in the WORD file you can select and image and then go to the FORMAT (pictures) menu and select compress for all of the bitmaps in the file. That will typically use 150 dpi by default that is adequate for most needs.

What is the max size of HDD I can use in my dc7600 CMT
I am using an HP dc7600 CMT which is working fine after upgrading to a Samsung 128GB SSD, Intel Pentium D 3.4 GHz, 4GB RAM, and an AMD Radeon HD 6450. I am running Win 8.1 Pro x64, with the most recent upgrade, and have absolutely no problems. I now want to add a second internal HDD, and wonder what is the max size I can go to. Can I go to 2TB, or am I limited to a lower figure? 1TB? 500GB? 250GB?
Will be glad for some help here, especially if it has been actually tried in practice.
Thanks in advance.
Best regards
This question was solved.
View Solution.You're very welcome.
Yes, they are very nice machines.
What a jump in performance when I swapped out the Pentium 4 620 mine had, for the PD 945, and tossed in 4 GB of memory.
That box will also run the Radeon HD 6570 with no problem too, which is what I put in mine.
The downside of that model is that there are no settings for ahci or raid.
I own or have owned every CMT since the d510 with the exception of the dc7900.
My main PC is now the 8200 Elite CMT which I installed W8.1 on.
It has an i7-2600 processor and 32 GB of memory, 1 TB SATA III hard drive.
I threw in a Radeon HD 6670 in that one.
Best Regards,

How to change the size of control´s prompt?
No matter the size of data to be displayed in the view suface prompt, the controls have the same size.
Does anyone here know how to change the size of control in surface prompt?HI,
In order to change the size of a radio button... one way you may consider is to Customise the Radio Button.
Place a Radio Button (RB) on the FP of a VI, Right-Click the RB > Advanced > Customise...
Click the Mode Button (most Left button) for Edit Mode
Right-click the radio button (the round image) now, you will see a list of actions i.e. Copy to clipboard, import picture ...You will see Four images under the 'Picture Item', those are the images that you will need to replace.
Prepare Four Images of the similar but larger expected size
*** Copy the 1st new image to clipboard. Back to the Picture Item and select 1st image. Then, select Import Picture (to replace the existing image)
Repeat *** for all four images.
Once done, change the mode back to original. Save the *.ctl
You are now ready to use the customised radio button!
Quick sample attached (sorry for the poor images created )
