Make JList Recalculate Component Widths and Heights
I have created a subclass of JList in which every item in the list has an associated icon and the text for the item is displayed underneath the icon. The JList is given the HORIZONTAL_WRAP layout orientation by default. I have an option to show the icon and the text or just the icon. When I change this property, I have the JList refresh itself to redraw the JLabels at their new preferred sizes. Currently I do it like this:
setVisibleRowCount(getVisibleRowCount()+1);
setVisibleRowCount(getVisibleRowCount()-1);I'm hoping there's a better way. The repaint() method makes the text appear or disappear, but does not adjust the size of the list items until the window is resized. I tried invalidate(), revalidate(), and validate(), but they had no effect whatsoever. I tried using updateUI(), which works the first time, but generates an exception if used more than once:

What kind of ListModel are you using? I ask because if it's a subclass of AbstractListModel then you just call the fireContentsChanged method for the entire list.

Is there any way to make column width and height 0 by using formula?
Eg:
=If (column = value) then Column width = 0px and height = 0pxHi Riaz,
Instead of kepping column width and height as 0, you can just hide the particular column by using the same function that you mentioned above, (if column = value) in hide..
You can just right click on the column->hide->hide if->dimension=value. -
Nested canvas in GridLayout can't get its width and height
Hello,
I have a class entitled DisplayCanvas, which will accept some parameters from an invocation in another class including a shape and message parameters. These parameters must be centered in the instance of DisplayCanvas.
For some reason, when I use this.getWidth() and this.getHeight() within my DisplayCanvas class, I get 0 and 0! I need the width and height in order to center the parameters the user will enter.
Why does the width and height result at 0? What can I do to get the width and height?
In my DisplayCanvas class notice the lines:
canWidth = this.getWidth();
canHeight = this.getHeight();
For some reason the result is 0 for each!

Java doesn't render a component until paint() is called so until then you are not going to have any size settings because the jvm simply doesn't know how big the visual component is. This makes sense when you think about what the jvm is doing. The layout manager controls the display of the components depending on the settings it is supplied. So until it knows how many components you want, where, what kind of spacing, etc, etc, etc, how can the size be determined.
The true cycle of events is therefore:
create an instance of DisplayCanvas,
add it to your container,
make the container visible (which renders the component),
get the size of the DisplayCanvas instance.
You are being hampered because your desired chain of events is:
create an instance of DisplayCanvas,
get the size of the DisplayCanvas instance,
add it to your container,
make the container visible.
This state of affairs is highly annoying and then leads to the next question "what do we do about that?". There is a cunning trick which is to get the jvm to render the component to an off-screen image, thus calculating the dimensions of the component so that you can do precisely the kind of enquiry on the object that you have been looking for. It should be noted that this may not be the visual size for all the reasons given above, but it is the "preferred size" for the component. Check the Swing tutorials and have a look at the section on Layout Managers for a run down on what that means.
Anyway, we can use this handy code sample to determine the preferred size for your component. Notice the call to "paint()" (normally you would never make a direct call to paint() in swing) and the "g.dispose()" to free resources:
package com.coda.swing.desktool.gui;
import java.awt.Component;
import java.awt.Dimension;
import java.awt.Graphics2D;
import java.awt.image.BufferedImage;
public class PaintUtil
public PaintUtil()
super();
public static Component paintBuffer(Component comp)
Dimension size = comp.getPreferredSize();
comp.setSize(size);
BufferedImage img = new BufferedImage(size.width, size.height, BufferedImage.TYPE_INT_ARGB);
Graphics2D g2 = img.createGraphics();
comp.paint(g2);
g2.dispose();
return comp;
}Before you make a call to getWidth() or getHeight() put in a call to "PaintUtil.paintBuffer(this);" and see what happens.
By the way, I can't claim credit for this code ... and I really wish I could remember where I got it from myself so I can thank them :) -
Changing af:messages width and height
Hi gang
Does anybody have a suggestion how I can expand the default width and height of the af:messages popup under JDev 11.1.1.2.0? From what I can see there are no styles defined in the skin, no properties on the component, and the inline style width/height properties are ignored.
Your help appreciated.
Regards,
CM.I have to agree with 9 of the 14 respondents Keyshia Cole's new nose is indeed natural looking :-)
The problem we're getting is two fold:
a) Occasionally our error messages have long words, the messages tag isn't hard wrapping, and this is resulting in a horizontal scroll bar.
b) Sometimes the number of messages displayed is greater than the vertical space, so we get a vertical scroll bar.
c) Sometimes both, which looks cr@p.
The combination can make the app less user friendly as the user has trouble assessing/reading the error messages.
While we can do some minor tweaking to minimize word length and number of error messages, the preferred method would be just to increase the size of the dialog.

How to create a map that is larger than the game in width and height?
hi,
i wounder how i can create a map(not the design) that is larger than the game in width and height, part of it will appear in the main page and anther part you can move to it after you press the arrow symbol, but the map is just one image so i want put it in line and out line the game page, and the out line part includes buttons and symbols the player can use, but it will be in line and the other part will be out line when you press the left arrow or the down arrow, how i can do that?
and is that possible to animate it so when the player press the arrow, will give it action to start the animation in one sec, i know how to animate it if that possible but i don't know which code i will use for the mouse click with the arrow symbol, and how to use the same code in the same symbol to start anther animation depending on which part of the map is on?I don't know a lot about mask and masked layers and how to work with the normal layers beside i will use some 3D graphics but not in the background, i will explain all this to you to be more clearly.
first i am using action script 3.0
close ex,
you have 2d map"image" 900*300 pixel.
this image contains some 2d symbols when you click will go to anther normal map (anther normal layer) so they must appear.
your game 320*320 px, and the place the map will show on 300*300, and there's basics objects will be in most pages including the page that show the map so i don't know a lot about how this will work with mask layers.
so you can only see the left side of the map image and what it contains, while there's two arrows one to the left and one to the right there's three cases here,
first when it show the left side(start from x:0 to x:300), the left arrow will not active when you press and the right arrow will start an animation that make the map image move to the mid side in one sec when you press.
in mid side (start from x:301 to x:600) the same left arrow will active when you press to send you back to the left side while the same right arrow will be active to send you not to the mid side but to the right side,
when moved to the right side the same left arrow will be active to send you to the mid and the right will not active when you press and depending on that,
first how to make the large image appear with the three sides in the same place without effecting the other objects "like disappearing them" ?
and the codes i need in the same left or right arrow symbol to make different actions with the same symbol when clicked depending on which part of the map is on. -
Java returning incorrect values for width and height of a Tiff image
I have some TIFF images (sorry, I cannot post them b/c of there confidential nature) that are returning the incorrect values for the width and height. I am using Image.getWidth(null) and have tried the relevant methods from BufferedImage. When I open the same files in external viewers (Irfanview, MS Office Document Imaging) they look fine and report the "correct" dimensions. When I re-save the files, my code works fine. Obviously, there is something wrong with the files, but why would the Java code fail and not the external viewers? Is there some way I can detect file problems?
Here is the code, the relevant section is in the print() routine.

}Edited by: jloyd01 on Jul 3, 2008 8:26 AMFigured it out. The files have a different vertical and horizontal resolutions. In this case the horizontal resolution is 200 DPI and the vertical is 100 DPI. The imgage width and height values are based on those resolution values. I wrote a section of code to take care of the problem (at least for TIFF 6.0)
private void setPageSize(int pageNum) throws IOException
IIOMetadata imageMetadata = _reader.getImageMetadata(pageNum);
//Get the IFD (Image File Directory) which is the root of all the tags
//for this image. From here we can get all the tags in the image.
TIFFDirectory ifd = TIFFDirectory.createFromMetadata(imageMetadata);
double xPixles = ifd.getTIFFField(256).getAsDouble(0);
double yPixles = ifd.getTIFFField(257).getAsDouble(0);
double xRes = ifd.getTIFFField(282).getAsDouble(0);
double yres = ifd.getTIFFField(283).getAsDouble(0);
int resUnits = ifd.getTIFFField(296).getAsInt(0);
double imageWidth = xPixles / xRes;
double imageHeight = yPixles / yres;
//if units are in CM convert ot inches
if (resUnits == 3)
imageWidth = imageWidth * 0.3937;

Pdf in new window full width and height
Hi i managed to create a new window and add a pdf to it :
var pdf = new air.HTMLLoader();
pdf.height = 600;
pdf.width = 400;
pdf.load(request);
mywin = window.open("",
"pdfWindow","height=600,width=400,top=10,left=10");
mywin.nativeWindow.stage.addChild(pdf)
But i would like to make the pdf scale to the width and
height of the window , i tried width = '100%' but then it doesn't
show a pdf
for the current result see :
ScreenOkay i created a test :
var pdf = new air.HTMLLoader();
pdf.height = 600;
pdf.width = 400;
pdf.load(request);
mywin = window.open("",
"pdfWindow","height=700,width=500,top=10,left=10");
mywin.nativeWindow.stage.addChild(pdf)
pdf.width = mywin.nativeWindow.stage.stageWidth
pdf.height = mywin.nativeWindow.stage.stageheight
But then the pdf doesn't show, i also think this wouldn't
work on resize of the window ?
Or is there a event that is triggered -

Change the width and height of Landscape Layout for a report in 10G
Hi,
I'm new to reports and when i built the report in report builder 10g, the layout orientation was 'Landscape', hence I assumed that it'll be a landscape layout.
However, the width and height fields of the main section are 11 and 20 respectively. However, the height should ideally be 8.5. When i try to change it I get the following error message :
Layout canvas must remain large enough to fit layout objects.
Could you please tell me how to change the height of this landscape layout to 8.5 from 20.
The report has several main frames within a repeating frame, since the same report has to run multiple times.
Is it possible to have a repeating page across pages (crossing the horizontal margin) and hence have some of the main frames move down to the next page. I'm trying to do this to then be able to reduce the height of the main section of the report to 8.5. Its not working though because I'm getting the following error :
REP 1814 : Report cannot be formatted. Object "vertically" can never fit R_Main (the name of the repeating frame enclosing all objects)
Thanks,
PriyankaTo reduce the Hieght, first make the layout design fit into the new value..

Specifying target width and height
I want to make one of my b to b links just a small pop-up
listing board members names which would open in front of the
current page. Do i create a separate html file to link to? If so,
how do I set width and height?
Is there some other way to do this?
TIA

will let you do
this.

[JS] Page item (rectangle frame) width and height
Following is my attempt at writing a function for width and height. It appears to work on rotated and sheared objects. Can anyone tell me if I'm on the right track?
>function WidthAndHeight(myRectangle) // Returns an array [width,height]
]var myRectangleTopLeft = myRectangle.resolve(AnchorPoint.topLeftAnchor, CoordinateSpaces.pasteboardCoordinates, true);
var myRectangleTopRight = myRectangle.resolve(AnchorPoint.topRightAnchor, CoordinateSpaces.pasteboardCoordinates, true);
var myRectangleBottomLeft = myRectangle.resolve(AnchorPoint.bottomLeftAnchor, CoordinateSpaces.pasteboardCoordinates, true);
]var d1x = (myRectangleTopRight[0][0] - myRectangleTopLeft[0][0]);
var d1y = (myRectangleTopRight[0][1] - myRectangleTopLeft[0][1]);
var myWidth = hypotenuse(d1x,d1y);
var d2x = (myRectangleTopLeft[0][0] - myRectangleBottomLeft[0][0]);
var d2y = (myRectangleTopLeft[0][1] - myRectangleBottomLeft[0][1]);
var myHeight = hypotenuse(d2x,d2y);
]return [myWidth,myHeight];
]function hypotenuse(d1,d2)
]]return Math.sqrt ( Math.pow(d1,2) + Math.pow(d2,2) );Dave, you are absolutely right (no surprise here) about always returning points. I'm not sure, but I think this may actually be an InDesign bug. At the end of the 'resolve' method the 'true' value is meant to indicate 'use ruler units', I believe. Having read the documentation, however, it does seem like certain transformation coordinate spaces functions only work in points.
To make this a more complete function, I've updated it to include a conversion to the current ruler units. I'm using the UnitValue object, and perhaps I'm misunderstanding something, but I cannot easily convert to a new UnitValue using the ruler measurements enumerations (it requires a string value to represent the target units). So I've had to include a switch function to get from the enumeration to the string value. Also, the UnitValue object does not seem to work with agates, and I haven't gone so far as to write my own conversion function for that, so the function has to exit with an alert if the user has agates as their ruler units.
If anyone can offer a more elegant way of dealing with this, it would be great. Or even better, some insight into why the resolve method does not seem to honour the ruler units. This _is_ getting a bit over-the-top for a simple width and height function. Maybe Adobe will consider just adding the property to the page item and putting us all (well, certainly me, anyway) out of our misery (I've put in a feature request).

Hi,
We are indexing file share with images and get the properties of Image Width, Image Height, Image Size (we show it as refiners in SharePoint after make it managed properties). Somehow when the picture is png format - we see only Size but not height and width.
Is that any setting that should be done in the file share (when i select an image in the windows explorer window i can see all its properties, and it seems that png files do expose the width and height properties
keren tsurHi Keren,
According to your description, my understanding is that when you tried to crawl file share with images, the ows_ImageWidth and ows_ImageHeight crawled property for PNG file could not be generated.
For your issue, I can reproduce your issue in my SharePoint 2013 environment. For a workaround, you can upload the PNG images into SharePoint images Library and they would work fine.
Best Regards,
Eric

I realize this isn't exactly the way that Flex works, but I
need some help here:
I have a UIComponent class that has graphics drawn inside of
it (using graphics api and sprites). I need to be able to detect
the width and height of this component. Since flex doesn't count
these when i request clip.width or clip.height, I am totally stuck.
The thing I really don't get is why in FlexBuilder3 I can see
the dimensions I want right at the top of the variables list as
$width and $height, but there is no way to get to them! Argh!
[IMG]http://keithguerin.com/personal/flexBuilderProtectedVars.gif[/IMG]I am having a similar problem, and this solution seems to not
be working.
I want to draw a box that's 10% height and 10% width of the
canvas (with a height and a width that's defined by percentages as
well) it's been drawn in. How do I do this? I can't seem to figure
out how to access these. My goal is to fill in boxWidth and
boxHeight in the code below.
My code for creating the rectangle is attached. Thanks for
any help. -
Sizing a scrollPane to fit its contents' width and height
Hi,
I have a MC loaded into a ScrollPane and have attempted to
detect the MC's width and height and use that to set the size of
the scrollPane per the documentation at
Adobe
Live Docs. I am probably not adapting the code correctly (well,
duh), but what I have isn't working and I don't know why. Does
anyone around here have a clue? Thanks in advance.OK, the forum ate my code :(
Not sure how to get it to display. Feel free to close the topic as it doesn't make sense. I'll ask elsewhere.
Thanks,

Hello, how can i change widht and hight on iWeb?
welcome to the forum, to change anything in iweb use the inspector panel. Choose page - layout to alter the width and height. The inspector panel is at the bottom of the page and the page set-up is the second icon along the top of the panel. Hope that makes sense and gets you up and running.
