Component size problem

I have a program in which i am using a SpiltPane in which the NORTH portion includeds a JDeskTopPane and in the South just a JTextArea. When i maximise the window the text area is scalled but the not the desktopPane. I deire the opposite, in which the desktopPane is scalled when the main application is changed size and not the text area (i want the textarea to be static, depending on the size the user has set it too)
any ideas?
thanks
Adam

I found that by using the method "setResizeWeight(double value)" of the JSplitPane class i could specify that i wanted the top panel of my application to resize when the window is expaneded.

Determining component size

We have app where component may be resized at runtime.
I kind of understand how components and containers are
resized using height, widht, percentHeight and percentWidth
settings and have gone through some of the articles on it on
internet. My question is there a property which gives size of a
component in pixels at runtime. It seems height and width
properties only contains the initial setting and is not updated at
runtime.
I know we can try to calculate component size using
setttings, parent settings and settings of parents parent etc.
Apart from being very trick, it will anyway not give the size if
component is resized at runtime.

I found the problem. height property does get updated with
the actual size at run time. However, I was looking at it in the
override function createChildren(). It is not available in that
function, so I guess it is initially updated later in the component
cycle. Now I capture the CREATION_COMPLETE event and can read the
height property there.

Get original component size in componentResized()

Does anyone know how to get the original component size (i.e. the size prior to resizing) of a JComponent after the componentResized() method has been called. I need access to the original and the new component size in the componentResized() method. I am trying to avoid keeping and maintaining lots of arrays of component sizes on the basis I might need a component's size if it changes.

This JPanel is managed by GroupLayout and all components in it have preferred sizes. All the layout for this JPanel is managed by the layout. I need the original component size (and new size) in the event handler method componentResized() because any component can be resized and the change in size affects other JPanels.
Does anyone know if it is possible to get the original component's size from the componentResized() method and if so, how.

HP 8750 Paper-Size Problem where it keeps telling me the paper is too big (it's set up for 11x17)

I've got an HP 8750 printer running with a Windows 7 Ultimate machine, and I've got a paper-size problem where it keeps telling me the paper is too big. It's set up for 11 x 17.
The actual wording on the printer is:
Paper installed is larger than needed. Press cancel to replace with correct size, if you wish to save paper, or press check mark to continue.
When you press the check mark it feeds the paper, but for a multi page-document I have to press the check mark for each page to feed.
How do I get it to print 11 x 17 paper without having to press the check mark for each page?

Is there a solution to Rapidweaver Stacks Cache size problems?

Is there a solution to Rapidweaver Stacks Cache size problems?
My website http://www.optiekvanderlinden.be , has about 100 pages and is about 250MB in size. Every time I open RapidWeaver with the Stacks-plugin, the user/library/cache/com.yourhead.YHStacksKit folder grows to several Gigabytes in size. If I don't manually empty the com.yourhead.YHStacksKit Cache daily, AND empty the Trash before i turn off my mac, my Mac still has problems and stalls at startup the next day. Sometimes up to 5 minutes and more before he really boots. If i have a been working on such a large site for a few weeks without deleting that cache, than my iMac doesn't start up anymore, and the only thing left to do is completely reinstall the iOs operating system. This problem doesn't happen the days i use all my other programs but don't use Rapidweaver.
Does anyone know a solution and / or what is the cause of this?

once more,
i just launched my project in Rapidweaver, and WITHOUT making any changes to my pages, the cache/com.yourhead.YHStacksKit folder filled itself with 132 folders (total 84Mb), most of them containing images of specific pages etc. The largest folder in the cache is the one with the images of a page containing a catalogue of my company, this folder is 7Mb. It seems by just starting up a project, immediately different folders are created containing most of the images in my project, and some folders with a log.txt file. Still i don't see the reason why it is filling op a huge Cache even without making changes to the project. I have 2 different sites, so 2 different projects, and i get this with both of them.

Size problem with Email sent from SAP

Hi everyone,
All our layouts today were developed with sap script
We started to send them by mail, using the standard way.
in the process they are converted to PDF format from OTF, because of this activity the size of the mail that I am getting is 1 Mega where as the source is only 300K (approximately).
We are already flagged the option of compressing.
As we see now we don't have any option to make the email to be smaller.
Is someone already encountered this problem? What option do I have? (Except of developing the layout again in Adobe)
Thanks allot
Udi
SD consultant

First thanks
Sayali Paradkar , we used in the past this function module, but it was even worse.
We started to use the standard process of sending mail.
As we understand the program of converting OTF format to PDF cause the size problem.
And its define to send PDF out of the SAP, also we are using SAP definitions to compress all files :nSE38 -> RSTXPDF3 -> option FLATE_COMPR_OFF = OFF
But still the mails are very big,
Thanks again

Tree component display problem when text too long???

hi all
whenever i use a tree component to display some sort of text, i run into problems when the width of the text being display for a node is larger than the width of the tree component.
Given: Tree tree1 with Node node1 and Child Node child1
When the text of either node1 or child1 is longer than the width of tree1, the text is displayed on its own single line UNDERNEATH the node images. this makes the text look like it does not belong to the group of children of a given node.
is there anyway to add maybe a text area or some sort of scrolling region to allow for any length of text for any node??
thanks everyone!

Yes, you can change the size of the tree node text field. Please see the "Tree Node Component Properties Window" section in the Help Contents within the IDE. Look at the info under the "Appearance" section.

New Quick Time frame size problem when viewing

Just upgraded to FCPv7 and am having weird issues with playing back video in the new QT player.
I have exported several different formats of the same 30s video(ProRes422, H264 etc) . When played back, the window /frame size of the QT window is way out. The file info shows the correct info, as a 320 x 180 frame size, but QT keeps displaying it as larger than this, with poor quality (like it has been enlarged). If i export exactly the same file as a 480 x 270, it plays perfectly. I know it must be wrong as the dimensions of the QT windows are the same for both!
I have further checked this by playing both videos in my macbook (prev version of QT), and both play at the correct size.
How can I get the new version of QT to play the 320 x 180 at "actual size"? as the option is greyed out if I click properties?
Thanks

see before my code looks like this

                comp.setBackground( Color.BLACK );
                add( BorderLayout.CENTER, comp );
            }now i am doing this:

          Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize();// get screen size
          comp.setSize(screenSize.width, screenSize.height); // set size to video component at the start
                add( BorderLayout.CENTER, comp );
            }i am not sure if this will fix my problem, i am keep running the test.

FLVPlayback component skinAutoHide problem

Hi guys!
I have a problem with FLVPlayback component's skinAutohide
property which works poorly when FLVPlayback component is the same
size as your stage. The skin only hides when I move my mouse very
slowly outside the FLVPlayback component.
Also making the FLVPlayback component smaller isn't an option
so what more options are there left?
Is there anyway to hide the skin by yourself?
I allready tried the following code, but I think this is very
unreliable (I get some errors when I move my mouse very quickly
over and outside the FLVPlayback component):
video.addEventListener(Event.MOUSE_LEAVE, mouseLeaveHandler);
video.addEventListener(MouseEvent.MOUSE_MOVE,
mouseMoveHandler);
function mouseLeaveHandler(event:Event):void {
video.skin = "";
function mouseMoveHandler(event:Event):void {
video.skin = "SkinOverPlayStopSeekFullVol.swf";

I am having the exact same problem. Thanks for info that this
is caused by movie being the same size as the stage. I am also
working on a solution and will let you know if I find one.

Component Font Problem

Hi all,
I have a problem with displaying fonts in a component which
has been masked, namely, list, dropdown and scroll pane. It all
seems to work fine, but when I load the first swf into the second
using a Loader object the fonts do not display.
I have tried putting the components in the parent swf as well
as the child.
I have also tried this:
StyleManager.setStyle( "textFormat", new
TextFormat("Verdana") );
StyleManager.setStyle( "embedFonts", true );
in both and
I set the ApplicationDomain to be
ApplicationDomain.currentDomain
Anyone got any ideas? Hope to hear from someone soon.
Thanks in advance

Javier,
Thanks for the response. When I first noticed the problem, the parent XLF had canvas dimensions that were about five pixels greater than the respective widths and heights of the Slide Show component. There was a visible space between the edges of the Slide Show component and the edges of the canvas. Likewise, the child XLF had about five to ten pixels between the edges of the canvas and the edges of the main background.
I have now resized the parent canvas to be about ten pixels greater on both sides, increasing even further the distance between the canvas edges and the Slide Show component edges, and saw no change.
I am reluctant to experiment further without knowing more about what you were seeing on your end. Can you be more specific about your test results? Thanks.

Component resizing problem in Vbox

Hi.. I am facing a peculiar problem.. I have a vbox which contains 5 components, each of which has a line graph and a legend.. But all of them need not be visible at a time.. It depends on the number of parameters returned from a webservice call... so at a time 1-5 of such components maybe visible... i do this by setting includeInLayout and visible to false..
Each of the components have height and width set to 100%. So I expect all the components which have includeinlayout and visible set to true to be equal in size... But if initially only one of the component is visible and then i want to show 2 components by setting these properties, the component which was visible initially is not resizing.. It is staying the same size as before making the second component visible... second component is getting correct size (half of the size of the VBox)..... Am i doing something wrong here? Can some component not reduce in size if another child added/included in layout of its parent?
Thanks in advance for your help!

Hi Philip,
This is my vbox declaration. Trendline has a linechart and a legend
<mx:VBox id="chartsContainer" width="100%" height="100%" verticalScrollPolicy="auto">
   <chart:TrendLine id="defaultTrendLineChart" width="100%" height="100%" includeInLayout="true" visible="true"/>
   <chart:TrendLine id="trendChart1" width="100%" height="100%" includeInLayout="false" visible="false"/>
   <chart:TrendLine id="trendChart2" width="100%" height="100%" includeInLayout="false" visible="false"/>
</mx:VBox>
And here is the code where i selectively include various charts in the display
var count:int = 0;
for (var parameterType:String in parameterTable)
   var trendLineChart:TrendLine = trendChartArray[count++];
   trendLineChart.includeInLayout = true;
   trendLineChart.visible = true;
   trendLineChart.Initialize();
   trendLineChart.SetView(bIsChartView);
   trendLineChart.LoadChart(dataProvider, parameterType, parameterTable[parameterType]);
I have stored all the children of the vbox in an array for easy fetching
var trendChartArray:Array = [defaultTrendLineChart, trendChart1, trendChart2];
parameterTable is a Dictionary in which number of parametertypes can vary from 1 to 3 depending on the result of a webservice call. The problem is that if initially i am showing only one chart and then i have to show 2 charts, the first chart's size is not getting reduced. But the second chart added is getting correct size.
Thanks a lot for your response.

Jsf datatable inside datatable component rendering problem.

I am creating an online survey application using JSF with IceFaces component library. The survey can have any number of questions. Each question can be any one of the types checkbox, radio button, etc with multiple options.
For this, I am using a datatable to dynamically add a question to the survey. Inside that datatable, I am using another datatable to add option to the survey.
Now the problem is, if I keep on click on add question button, in the outer data table, question is being added without any issue. Once I click on inner data table to add a option to any of the added questions, I am able to add. But after that, if I click again on add question button, it is not working.
This is my xhtml code:
<ice:dataTable id="icePnlQuestionAdd" var="questAdd" value="#{createSurveyManagedBean.surveyQuestionList}">
<ice:column>
<table border="0" cellspacing="0" cellpadding="0">
<tr>
<th><ice:outputText value="Question English" style="white-space: nowrap;" /></th>
<td colspan="15">
<ice:inputText id="QuestionEn" style="width:485px;" value="#{questAdd.questionEn}" />
</td>
</tr>
<tr>
<ice:dataTable id="icePnlOptionAdd" var="optionAdd" value="#{questAdd.surveyQuestionOptionList}">                               <ice:column>
<th><ice:outputText value="Option " /></th>
<td><ice:inputText id="OptionEn" value="#{optionAdd.optionEn}" /></td>
</ice:column>
</ice:dataTable>
</tr>
</table>
</ice:column>
</ice:dataTable>
This is the add question method:
public String addQuestion() {
SurveyDTO addSurveyQuestionDTO = new SurveyDTO();
questionNum = surveyQuestionList.size();
addSurveyQuestionDTO.setQuestionNum(questionNum);
surveyQuestionList.add(addSurveyQuestionDTO);
return "createSurvey";
This is the add option method:
public String addOption() {
FacesContext context = FacesContext.getCurrentInstance();
if (context.getExternalContext().getRequestParameterMap().get("questionNum") != null) {
String questionNum = (String) context.getExternalContext().getRequestParameterMap().get("questionNum");
int selectedQuestionNum = Integer.valueOf(questionNum);
SurveyQuestionOptionDTO surveyQuestionOptionDTO = new SurveyQuestionOptionDTO();
surveyQuestionList.get(selectedQuestionNum).getSurveyQuestionOptionList().add(surveyQuestionOptionDTO);
return "createSurvey";
}

Bind the h:datatable in the jsp to UIDataTable component in your java code. Then when the action method is invoked, use DataTable.getWrappedObject() to get the model. Cast the model to whatever your type is (List, Array...) and then iterate through the model to process individual rows.

JScrollPane + Component sizes before display

I was recently presented with a minor quandry.
I have a JPanel which needs to occupy a minimum fixed amount of real estate on my application's GUI, call it 'checkbox_jpanel'. The problem is that as the user operates the application, more and more checkboxes will be added to it. This works fine until I reach the size limit of the JPanel.
The obvious solution seemed to be to use a JScrollPane, and simply tuck the checkbox_jpanel inside of it. That way, I could dynamically resize the JPanel, and the JScrollPane could take care of displaying it.
Simple, until I realized that there's no good way to ask a layout manager how much space it had planned to let a given component take up, including buffer pixels. I can't even ask the component itself because, having not yet been drawn, it doesn't know how big it is either.
Currently, I'm able to get this strategy to work by guessing - eyeballing the number of pixels + space - each new checkbox takes up for the height * the number of items, and the width is based on the largest constant + (constant-intended-to-represent-average-character-width*letters in text portion of checkbox) among the set of checkboxes. I use that width and height to set the preferredSize of the JPanel i'm actually adding to.
I wince when I look at that code.
The comment above it says "This really needs to be done correctly."
How could I do this 'correctly' ?
The only thing I've been able to come up with is almost as ugly; make the checkbox_jpanel some insanely large size that will always encompass EVERYTHING, insuring that the checkboxes will be drawn, force/wait for the redraw, and then recalculate the width/height, and reset the panel to the desired (correct) width and height. I don't know if I could get this done without a bit of flickering, and really, everything about it screams 'non-optimal solution'.
Any thoughts?

Just an idea: the sizes become calculated when the components become visible OR when the application frame is packed... perhaps you could use a call to pack(), then do your job, then finally show your frame ?

Applet-Panel, background color and size problem

I am writing an applet with simple form.
Form is having 3 rows and 2 cols (label and textfield). Each row I want to display in different color. So I created each row with 2 separate panel (one for label and one for text field - of which I set the backgroung color).
The total form is in one panel with grid layout (2 colmns).
My problems are
1)The space between label and text field (col width) can not be resized. I tried to use setSize but not giving any effect.
2)Another problem is when I am seting the background color, the textfield is also changing the color (textfield I want to white color only). This does not have any effect on Choice
3)The first label I wanted to use simple break but could not. I tried \n\t, \n, chr(13) + chr(10) etc but not getting any result so created separate panel.
My code goes here:
import java.awt.*;
import java.applet.*;
import java.awt.event.*;
public class test1 extends Applet{
protected TextField refnoTextField=null, payerTextField=null, amtTextField=null;

I do not want to go into detail, but there are some hints you can follow.
I am talking about AWT, not swing, you should decide which one you will use and don't mix the two of them.
If you want to run your applet in current browsers without requiring the java plugin, you should be aware, that most browsers support old versions of java and many convenient methods and classes are missing :-(
So
You can change the size of a label by putting it in a panel ( labelPanel ), whose layout is set to FlowLayout. Then you put in labelPanel another empty panel ( emptyPanel ), whose layout is set to null, and you set the width of the empty panel to whatever you want ( this is the gap between the label and the next component ), an the height to the least nonsero number possible, i.e. 1. Well, you can add to the labelPanel more components, if you wish. So, when you want a gap, use an empty panel with a fixed size.
You cannot use line break in a label. You should place more labels in a panel instead. I am not sure if the direction of FlowLayout can be set to vertical, but very probably it can. If so, that is your solution. If not - see what other layout managers you have available, but make sure your choice belongs to java.awt ! BorderLayout allows you to use up to three labels (=> 3 lines). And if nothing fits your needs, ... write a layout manager.
Well, hope I could help.
