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.
CM.

Changing video frame width and height...
In Adobe Premiere Pro CS 5 I cannot seem to produce (output) a video larger than frame width: 720 and frame height: 480. The video is recorded in full HD 1920 x 1080p but after editing and adding effects in Premiere Pro CS5, the video changes to only 720 x 480.
1) Where are the settings in Premiere Pro changed to produce a video size of frame width: 1280 and frame height: 720 or even frame width: 1920 and height: 1080?
2) Is it possible to produce a video at 1920 x 1080 or is 720 x 480 the max?
Your time is appreciated.John,
For now I will be using the videos for youtube promos and viewing on desktops but if I were, I would more likely output to DVD. From what I understand it doesnt matter if I output 720 x 480 or 1920 x 1080 if it's going on youtube, however I would like the best quality video possible given that these videos wont be very long. (Elaborate on this if you can clear some stuff up for me).
Also, I may have mislead readers with my thread title "Changing video frame width and height." I guess a more accurate title would be "How to Change frame width and height of Video Output." Don't get me wrong 720 x 480 looks great on my desktop, but I would also like to output one at 1280 x 720? -
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..

How to change the width and height of the visible part of the of the report
I have define a report with paper size 'Letter', orientation 'landscape' and 30 columns. Dynamically I am changing width of columns and suppressing many columns of the report.
Mostly using first 16-20 columns and others get suppressed.
Now problem is that when navigating the report thru crystal viewer, a huge blank spaces getting display on right of the report. When we take jump to some part of report thru navigation tree, the whole report gets shifted to left and only blank part is visible and it is required to scroll left.
Even printing is not working correctly.
Is there any way to change the width and height of the visible part of the report in the viewer thru .net classes? Setting the width and height of the report in Load event handler doesn't help.
Example: CrystalReportViewer1.Width = 200; - is not helping.
Is there any other solution?
Please let me know.
Thanks
Mahesh PatelHi Yogesh,
Your suggestion 'reportDocument.PrintOptions.PaperSize=PaperSize.PaperLedger;' along with 'PaperOrientation' setting as follow works fine. I tried to switch between Landscape and Portrait depending on report width.
reportDocument.PrintOptions.PaperOrientation = PaperOrientation.Landscape;
But problem with crystal viewer remain as it is.
While navigating report thru crystal viewer, when we take jump to some part of report thru navigation tree, the whole report gets shifted to left and it is required to scroll left.
Thanks for your very good suggestion.

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.

Camera Image Display - changing width and height.
Ok, so I wrote this simple program, but for some reason i cant control the offsets, width and height (attributes related to the image display on front panel). When i go to MAX, i am able to change these attributes, why cant i do it in labview? Any ideas?
You need to put the width and height controls inside your loop to adjust while running.
From the image you provided, the width and height are set once outside the loop, and then you sit in the loop, so they can't be adjusted again. -
Change width and height in a rich symbol
Hi!
I'm trying to build a rich symbol in fw cs4 so I can use it in multiple projects and I'd need some boxes to scale to certain sizes I would assign through the properties panel.
Is it possible? I've seen in former versions that both width and height are read-only but I can't find anything for current version.
Also, if possible, can I set the x and y position?
What I've been trying is:
box.height = height;
box.width = width;
where box is an element (I've changed other properties and it works) and height and width are values (which also work)
Thanks a lotI need to know if this is possible, too!
Hopefully this is working somehow.

How do I save the width and height of a photo for repeated use?
How do I save the width and height of a picture for repeated use, rather than having to enter it each time in the 'new file' box?
Thanks, Ed Jackson.It could be that I'm older and have forgotten. I'm now 73 and will admit I have forgotten many things over the years. I have been using Photoshop since Photoshop version 3. And can not really recall which features or changes were made in ever version of Photoshop I have installed. Adobe has added many features over the years. The number of bugs introduce has also greatly increased after CS3. "New Doc Sizes.psp" in your user id preferences is edited using the two buttons in the new document dialog.
As for guide lines in new documents Photoshop CS6 or CC seem to add some for video file presets with guide lines. I do not know how to edit or add guide line to new doc presets. Guide line actions are easy to create. I have also seem some guideline in new documents when I did not expect any perhaps a new bug. Photoshop like most software has bugs. If you do not see Adobe new presets perhaps you copied an old "New Doc Sizes.psp" over Adobe's newer default file or Adobe migrared you presets and wand wiped their presets out. There are bugs. Close Photoshop down and rename your current "New Doc Sizes.psp" in you user id Photoshop cc preferences folder and start Photoshop it will add a dedault "New Doc Sizes.psp" file see if you see Adobe new presets in the new doc pull down when you select video and film... -

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 :) -
How to set a minimum width and height for a stage or scene?
Hello,
Does anyone how to set a minimum width and height for a stage or scene?
I tried listening for width/height property value changes and then adjust the width/height if necessary, but that causes unpleasant flickering of the window.
In JavaFX 2.1 beta SDK for Mac OS, the Stage class has setMinWidth() and setMinHeight() functions which work very well.
I'm wondering what's the equivalent way to do that when using the FX SDK for Windows.
Any help is appreciated!
Thanks.I was wondering how to enforce a minimum stage size with JavaFX 2.0.3.The same flickering way you are currently doing it. See: http://javafx-jira.kenai.com/browse/RT-15200 "Need a way to set the minimum size of a window"

There is a way to insert an image inside of the html code
with width and height already? I mean, now, if I want to insert an
image at the code, goes only <img src="images/test.gif" /> I
d like that if I insert an image it goes as: <img
src="images/canto_topo.gif" width="8" height="29" />
is possible in dreamwaver to do that?
Thanks!
VismonaIf you insert the image using the "Insert Image" function, DW
will
automatically insert the width and height.
Or, if you'd rather insert them the way you are, in the
Property Inspector
on the far left, click the dimensions next to the Image
field, and DW will
automatically add (or correct) the width and height.
Hope that helps,
