String height
hi
I dont know whether this is the correct forum to ask my doubt.
i calculated the string width of a string with a font style,font size,name etc.
eg:
Font font = new Font(fontName, style, size);
JButton jButton = new JButton();
FontMetrics fontMetrics = jButton.getFontMetrics(font);
width = fontMetrics.stringWidth(inputString);
i also want to get the height of the string also.how can i get it.i want the height of the string only based on font name, style, size.
is there any method to find it.
plz help me.
rgds
FontMetrics.getHeight
FontMetrics.getMaxHeight

Dynamically size movieclip to fit text's string height and width
Hello,
I am trying to dynamically size a movieclip to fit the size of a text's string height and width (This text is inside the movieclip)
here is my code so far..
var Font1_ = new Font1();
var Format2:TextFormat = new TextFormat();
Format2.size = 36;
Format2.align = TextFormatAlign.CENTER;
Format2.font = Font1_.fontName;
var MessageBox:MovieClip = new MessageBoxMC();
MessageBox.Text1.defaultTextFormat = Format2;
MessageBox.Text1.embedFonts = true;
MessageBox.Text1.antiAliasType = AntiAliasType.ADVANCED;
MessageBox.Text1.wordWrap = true;
MessageBox.Text1.width = 800;
MessageBox.Text1.height = 400;
MessageBox.Text1.textColor = 0xFFFFFF;
MessageBox.Text1.cacheAsBitmap = true;
MessageBox.Text1.mouseEnabled = false;
MessageBox.Text1.text = String("Use the Arrow Buttons to move");
MessageBox.width = MessageBox.Text1.width;
MessageBox.height = MessageBox.Text1.height;
MessageBox.x = 400;
MessageBox.y = 200;
addChild(MessageBox);
this isn't working for me.. anyone know the best way to do this?
I also want the text to be centered in the movieclip, with a border of around 2-4 pixels
I am also not sure if i should be using text.length? any advice and input is greatly welcomed.
thanks in advance!Essentially, you need to check for a change in .textWidth or .textHeight, which are different from .width and .height.
This code works for me (assumes a background box called bg and a foreground text instance fg inside a moveclip and an X and Y bounds offset variable to say how far away you want the box from the text and a textFrameNudge to provide a tweak value).
// Resize background box
thisBox.bg.x = thisBox.fg.x - boundsOffsetX + textFrameNudge; // I'm using .4 as the tweak value for textFrameNudge
thisBox.bg.y = thisBox.fg.y - boundsOffsetY;
thisBox.bg.width = thisBox.fg.textWidth + boundsOffsetX*2 +textFrameNudge*thisBox.fg.getTextFormat().size;
thisBox.bg.height = thisBox.fg.textHeight + boundsOffsetY*2; -
Access Standard property(eg Fixed Height) of an iview in code
Hi ,
I have downloaded the standard URL iview's par(com.sap.portal.httpconnectivity.urliviews.par). I want to access the property 'Fixed Height' in the code. The component profile of the par doesnt contain the above attribute(and many other standard attributes which we get to see in the property editor of the iView). Can somebody please help me in this regard.
Regards,
PrathameshHi,
I would suggest you to use the PcmConstants.ASPECT_ADMINISTRATION for Constants.REQUESTED_ASPECT in environment.
Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY, IPcdContext.PCD_INITIAL_CONTEXT_FACTORY);
env.put(Constants.REQUESTED_ASPECT, PcmConstants.ASPECT_ADMINISTRATION);
env.put(Context.SECURITY_PRINCIPAL, request.getUser());
InitialContext iCtx = null;
String roleID = "pcd:portal_content/DanielContent/DanRole";
try{
iCtx = new InitialContext(env);
PcmAdminBase adminBase =
(PcmAdminBase) iCtx.lookup(roleID);
IPcdAttribute attribute = (IPcdAttribute) adminBase.getPcdContext().getAttributes("").get("com.sap.portal.iview.Height");
String height = attribute.get().toString();

Strange Behaviour setting column width & height programmatically
I'm trying to set the height and width of an image by storing the image, height and width in the database at the row level.
OATableBean table = (OATableBean)webBean.findIndexedChildRecursive("QuoteLinesRN");
OAImageBean lineImageBean = (OAImageBean)table.findIndexedChildRecursive("ImageItem");
//Next 4 lines set the image file name from the data in Segment1 - they work as expected
FixedBoundValue imageDirectory = new FixedBoundValue(APPS_MEDIA_DIRECTORY);
OADataBoundValueViewObject statusBinding = new OADataBoundValueViewObject(lineImageBean, "Segment1");
ConcatBoundValue statusCBV = new ConcatBoundValue(new BoundValue[] {imageDirectory, statusBinding});
lineImageBean.setAttributeValue(SOURCE_ATTR, statusCBV);
//Now here is the funny part -
OAMessageStyledTextBean heightBean = (OAMessageStyledTextBean)webBean.findIndexedChildRecursive("Segment2");
OAMessageStyledTextBean widthBean = (OAMessageStyledTextBean)webBean.findIndexedChildRecursive("Segment3");
String height = (String)heightBean.getValue(pageContext);
String width = (String)widthBean.getValue(pageContext);
lineImageBean.setHeight(height);
//Setting the width doesn't do anything if I set the height. And the image displays miraculously at the dimensions set in the actual physical file itself, for both height and width.
//The values I have in the table to get the height and width are completely irrelevant.
//Except I need to make a string out of the OAMessageStyleTextBean or the value for height and width will be as I specify ie. if I instead use: String height = "300" the height will be 300.
//But why is the height and width not using the values I specify in the table as Segment2 and Segment3?
//Is it because I'm not explicity setting the same index when creating the OAMessageStyledTextBeans as I used for my OAImageBean?I found some issues.

Dynamically set flash chart height?
Hi,
I have a flash chart that includes a selector that alters the query for the chart. Depending on what the user selects, the chart shows a different number of rows (this happens to be a stacked horizontal bar chart, but this could apply to any chart type). I would like to be able to dynamically set the chart height based on the number of rows the query returns. If I set it too small and the user makes a choice that returns a larger number of rows, the chart bars are compressed to the point where the labels are unreadable or omitted altogether. Conversely, if I set the height to a larger value and the user makes a selection that results in a small number of rows, the chart is overly extended and hard to read.
I am able to calculate what I'd like the chart height to be using a page item and a before header process. But I can't figure out how to pass this value to AnyChart. I tried using an item substitution (e.g., &P7_CHART_HEIGHT.) as the value for the chart height on the Chart Attributes/Chart Settings page, but this attribute requires a non-zero numeric value. I tried to figure out if I could alter the chart XML, but could not figure out how to do it and I'm not sure item substitutions would be passed in the XML anyway.
Is there a way to dynamically set the height attribute of a chart at page load time?
Thanks,
MikeHi Mike,
You can update the Region Source of your chart, replacing the substitution strings *#HEIGHT#* with the reference to your page item *&P7_CHART_HEIGHT.*. So your chart region source should then look something like the following(note that I've trimmed some lines for display purposes), and when the chart is run it will pick up your setting for the height, based upon the value returned from your Before Header process:
<object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000"
codebase="#HOST_PROTOCOL#://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=6,0,0,0"

Wiki whitelist.plist not working here's the script and steps taken
1. whitelist.plist created according to instructions in wiki admin manual.

3. File permissions set to allow _teamsserver access like other files in directory.
4. Webserver restarted.

The problem is that the Wiki just fails if there is any problem with your whitelist, with no warning. To see the fault you have to look in the console log. There you will see something like this, which indicates a faulty whitelist file:

X-Position from a computed field in Datawindow
Hi all
I have a computed field in the DataWindow. This should fix CF are at the position X. The width and the height are taken out of the data in the DB and is always different.
Now is the CF are always fixed on X and the width goes to the left.
example:
x = 2600
Width = 500
The CF is then positioned so that it is not related to the width of the X position. So always dynamically to each set.
How can I use the expression for Programming.Hi,
Is this the effect what you are looking for?
Below is the export of a datawindow. For the default x-position and width of the CF I had taken 800 for both; which might be confusing.
And the columns you can make invisible or hidden if you want to.
The expressions for the CF are.
x="800~t800 + 800 - width " y="40" height="80~t height " width="800~t width "
The width and height in the expressions are the column names that might have been stored in the database.
It is a 12.6 export; save it into a text file.
If you are using 12.5 just change release to 12.5 on the second line and try to import the file.
For older versions next to the release line you might have to delete some properties that didn't exist yet in that version for example the gradients. Importing will give errors and the position of the
error property. It can be a bit tedious to find and delete them.
One imported then view it in run-time.

How do I embed YouTube or Vimeo video in an apple mail message
Is there an easy way to embed YouTube or Vimeo video in an apple mail message?
I've tried using command+i (same with share feature) on a YouTube page ... looks great except I get missing plugin error on video.
I'm up to date on Flash plugin, running Safari 6, OS X 10.8. No old Flash files in the internet library.
Any help is appreciated!There's an HTML validator built in to the editor and it will, by default, throw out all but the simplest HTML tags.
The Apple document, Mac OS X Server, Wiki Server Administration V 10.6 explains all the gruesome details. But here's the solution that I use:
Change to the Wiki Server's directory by using
cd /Library/Application\ Support/Apple/WikiServer
If it doesn't exist, create a file called whitelist.plist:
sudo touch whitelist.plist
The file will be owned by root and all members of the _teamserver group. The latter is required for the Wiki service to have access.
Then edit the file with any appropriate editor -- I like vi:
sudo vi whitelist.plist
The file needs to have very specific formatting. This one should get your YouTube embedded HTML working:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<key>protocols</key>
<array>
<string>scp</string>
</array>
<key>styles</key>
<array>
<string>font-size</string>
</array>
<key>tags</key>
<dict>
<key>object</key>
<array>
<string>width</string>
<string>height</string>
</array>
<key>param</key>

<string>name</string>
<string>value</string>

<array>
<string>src</string>
<string>type</string>
<string>width</string>
<string>height</string>
</array>
<key>script</key>
<array>
<string></string>
</array>
<key>hr</key>
<array>
<string></string>
</array>
</dict>
</dict>
</plist>
After making changes or additions, save and close the whitelist.plist file then restart the Web service using the Server Admin application.
If you aren't at all familiar with vi, then you may want to instead create a text file on your desktop, put the content into it, then move it to the right location and change its ownership and permissions.
Hope this helps. -
Hello all
I created a whitelist.plist file for our wiki to allow embedding google videos and youtube etc.
However, all videos are automatically resized despite adjusting dimensions and fullscreen is disabled. Additionally, fonts remain uneditable. Furthermore the whitelist has caused problems with user permissions, allowing any user to edit and add new pages.
any help is greatly appreciated.
here is the code:

I posted my findings on a similar thread.

I cannot get it to work either, and I have tried a number of approaches. I think this feature is pretty flakey.

Applet Does Not Receive Parameters Nor Display Defaults
My applet will not display a Ellipse either via the default values in my java code nor via the parameters given in the HTML document. Does anyone see what I'm doing wrong here? Here are both my documents:
import java.awt.geom.*;
import javax.swing.*;
import java.awt.*;
import java.util.*;
public class CircleByParam extends javax.swing.JApplet
private Ellipse2D.Float circle;
private float x, y, w, h;
private Color circlecolor;
public void init ()
String xcoor = getParameter("X");
String ycoor = getParameter("Y");
String width = getParameter("W");
String height = getParameter("Y");
String fillcolor = getParameter("FillColor");
if (xcoor != null)
x = IntVerification(xcoor);
else
x = 25;
if (ycoor != null)
y = IntVerification(ycoor);
else
y = 25;
if (width != null)
w = IntVerification(width);
else
w = 25;
if (width != null)
h = IntVerification(height);
else
h = 25;
if (fillcolor != null)
circlecolor = ColorVerification(fillcolor);
else
circlecolor = Color.BLUE;
private int IntVerification (String value)
int number = 5;
try
number = Integer.parseInt(value);
catch (NumberFormatException e)
this.showStatus("Bad parameter " + value);
return number;
private Color ColorVerification (String value)
//Assigns color to BLACK by default
Color color = Color.BLACK;
try
color = Color.decode(value);
catch (NumberFormatException e)
this.showStatus("Bad parameter " + value);
return color;
public void paint (Graphics2D screen)
Graphics2D screen2D = (Graphics2D)screen;
screen2D.setColor(circlecolor);
BasicStroke pen = new BasicStroke();
screen2D.setStroke(pen);
circle = new Ellipse2D.Float(x,y,w,h);
screen2D.fill(circle);
HTML Document:
<HTML>
<HEAD>
<TITLE>Java 21 Days - Day 12 Exercise 1</TITLE>
</HEAD>
<BODY BGCOLOR="WHITE">
<APPLET CODE="CircleByParam.class" height = "400" width="400">

<param name="H" value="25">
<param name="FillColor" value="#996633">
This applet requires a Java-enabled browser.
</APPLET>
</BODY>
</HTML>Nevermind I figured it out, needed to make sure the paint parameter was (Graphics screen) rather than (Graphics2D screen)

Cann't change appete's appearance
I'm using netbeans IDE to build an applet which can work for both sun jvm and microsoft jvm.
I copied a simple "Hello world" applet from internet as below and built it in netbean IDE using javac.exe under java1.1. It worked in appletviewer and in IE 6(mjvm). the only problem is: I cann't use Applet.setSize(); to change the size of the applet in IE and cann't change the position of the string in applet by changing the (x,y) in Graphic.drawingString(String s, x, y) . All these things can be changed in appletviewer.
import java.applet.Applet;
import java.awt.Graphics;
public class testApplet extends java.applet.Applet {
/** Initialization method that will be called after the applet is loaded
* into the browser.
public void init() {
super.setSize(500, 600);
validate();
public void paint(java.awt.Graphics g) {
g.drawString("Hello world!", 200,300);
I'll appreciate it if somebody can explain this .
Thanks
Janethe position of the string in applet is relative to the displayed size of the applet so you can set the position of the string within the applet by passing it as parameters to the applet through the param tags like this:
<applet code=testApplet.class width=500 height=600>
<param name=width value=200>
<param name=height value=300>
</applet>
and then in your applet class you can retrieve and set the param values like this:
import java.applet.Applet;
import java.awt.Graphics;
public class testApplet extends java.applet.Applet {
String width = "";
String height = "";
/** Initialization method that will be called after the applet is loaded
* into the browser.
public void init() {
super.setSize(500, 600);
validate();
//retrieving parameters from the param tags
width = request.getParameter("width");
height = request.getParameter("height");
public void paint(java.awt.Graphics g) {
//setting the parameters within the g.drawString() method
g.drawString("Hello world!", width, height); -
How to add events to a ordinary html tag

i want to add event and bean for the <<< writer.write("<input type=\"button\" name=\"but\"/>"); >>>line of code, which is nothing but a button. I can added using JSF concept. but the requirement is like this. I have to add normal html tag for which i have to use bean and events as well.
Can anyone give suggestion for thisI will give a clear example
writer.write("<h:outputText id=\"txt\" value=\"Just a Display\" />");
writer.write("div");
this 2 lines is in endcodeEnd method. The output text wont display the msg.
even i am writing before the end tag
Here is the full code
================
public void encodeBegin(FacesContext context) throws IOException {
ResponseWriter writer = context.getResponseWriter();
writer.startElement("div", this);
writer.writeAttribute("id", getClientId(context), null);
String width = (String)getAttributes().get("width");
String height = (String)getAttributes().get("height");
String style = (String)getAttributes().get("style");
style= (style!=null) ? style + ";" : "";
if (width != null) style += "width:" + width + ";";
if (height != null) style += "height:" + height+ ";";
writer.writeAttribute("style", style, null);
String styleClass = (String)getAttributes().get("styleClass");
if (styleClass!=null)
writer.writeAttribute("class", styleClass, null);
String title = (String)getAttributes().get("title");
if (title!=null)
writer.writeAttribute("title", title, null);
public void encodeEnd(FacesContext context) throws IOException {
ResponseWriter writer = context.getResponseWriter();
writer.write("<h:outputText id=\"txt\" value=\"Just a message\" />");
writer.endElement("div");
writer.write("<h:outputText id=\"txt\" value=\"Just a message\" />");
This line is not executing

Number Of Visible Rows in a ScrollPane
Hi All,
I'm a little embarassed about needing help with something like this but I've tried several approaches and I'm just not getting it!
I have a JTextArea inside a JScrollPane and basically I want to introduce a little algorithm where I set the min, max and preferred sizes of this combo-widget to control real-estate usage (ie. only take up the minimum number of rows to display the text, but never more than a maximum configured by the user - it's a little different from the default behavior)
I would need a way of querying the JScrollPane to find out how many visible rows he's actually displaying at a moment in time.
My most promising (but flawed) attempt so far has been to set a listener on a viewport change event, and then to get the viewport extent height and compare it to the JTextArea's string height (which I was hoping coresponded to the height for one line of text).
double viewPortHeight = vp.getExtentSize().getHeight();
// get the height of one line of text to determine the
// number of rows being used
double textHeight = textArea1.getBounds().getHeight();
...but of course they're tracking one another. How do I get the height of a single line???Hi Dubwai,
I'm not sure I understand what you are trying to
achieve. Could you explain more about why you have > to constantly resize?Basically, the JTextArea/JScrollPane combo will be used in a table renderer for a few very important string columns in a table. There is no upper limit on the amount of text which can be entered in the column and the information in those columns is important enough that the customer has specified that they would like the entire thing to be visible as often as possible. They are defining a maximum number of rows (5-6) for one entry beyond which I will be able to put a scrollbar up. The width of the column for these fields will be fixed (at about 40 chars).
Additionally, real-estate in the table is at a bit of a premium I also don't want to waste any space in it by showing 2 rows for an entry where 1 row would suffice.
In a nutshell, I need a text area that is aware of how much space it requires and which will always try to minimize the number of rows it takes up. I thought that by determining how many rows were necessary for displaying a given bit of text, that I could force the JScrollPane size accordingly.
I'll spend some time looking at setRows(), but from looking at the API I got the impression that that only ultimately affected the preferred size. I was really hoping for a bit more control - for these specs, the minimum, maximum and preferred size will all be the same.
