Moving and Resizing UIComponents

Hi,
I am making a flex application in which I am drawing Square,
Rectangle,Ellipse, line,etc with flex UIComponent.
I want to Moving and Resize the UIComponents .
And what would be a better way to put UIComponent on some
container and resize and move the container ? Or directly move and
resize the UIComponent ?
Can any one help me ??

Hello all,
regarding what I asked about, I've found this https://help.ubuntu.com/community/Resiz … Partitions
So the question now is about moving. If I dd sda5 to sda4 will I have to set something up for it work? Like some offsets/adresses?
If I am able to move sda5 to sda4, the rest will be fairly easy. Any about my partitiong layout - it's manual, I've used fdisk, cryptsetup, mkfs and the lvm tools that come with the arch install iso.
Also some have misunderstood - currently everything but the boot partition, which is on another drive, is encrypted - in one LUKS partition and inside it there is an LVM with the different partitions.
I've tested on a virtual machine by doing the following:
unmount partitions
move the luks partition by using dd with opts bs=4096 conv=notrunc,noerror,sync
after that follow https://help.ubuntu.com/community/Resiz … Partitions
Worked like a charm(if you need to remove mappers use dmsetup).
After that: the uuid's of the lvm's are the same so that's cool. Just need to get the UUID of the new luks partition and set it in grub's cryptroot parameter.
That's all
Still I think I will backup everything first, then I will try this.

After moving and resizing control, some controls don't redraw properly as the cursor passes over them.

I have a top-level VI with three panes (two splitters). One of the panes contains nested tab controls. One of the tab pages contains six XY-graphs, a table and some decorations.
I use a subVI to resize and relocate the tabs and contained controls. All this is working fine, and everything looks fine after the resizing is complete.
The problem is when the cursor passes over certain controls (the chart legends and the table column headers for example), they redraw with gray boxes. The problem only occurs after enlarging the window from its minimum size. It goes away if the window is resized back down to minimum.
Anything that causes the window to redraw, like another resize or minimize/restore, properly refreshes the screen.
Has anyone seen this problem, and have a workaround?
The problem exists in development environment or built in LV 9.01 or LV 2010.
Thanks!

Thanks again for taking a look at my problem.
force redraw - This is apparently only available in LV2010. I did give at a try, but it did not prevent the problem, nor did it correct the problem once the gray boxes appeared.
disable updates (on a graph) - This apparently only applies to 3-D graphs, which is not what I am using in this case.
disable front panel updates - I tried disabling updates before moving/resizing the front panel controls, then re-enabling updates afterwards. The problem is exactly the same as before. Once the move/resize is complete, passing the mouse over the table column headers or the graph plot legend results in the gray boxes.
I would appreciate any other suggestions you may have.
Again... the problem is not that the moving and resizing don't work. They work fine. But once the resizing is complete, passing the mouse over the legend or table column headers causes gray boxes to appear.
Thanks!

Cropping when moving and resizing a cropping rectangle

I created a program that crops an image and displays the cropped image but I'm trying to add more functionality
by making it movable and resizable. The rectangle moves and resizes but it only crops an image when user draws the rectangle and not when moved or resized. I know that the X,Y, height and width position of the rectangle would need to be updated but I'm not
sure how I can accomplish this being new to WPF. Below is my user control "CropControl and the code behind. Also, I'm implementing my code using MVVM framework.

Hello HotSawz,
The ResizeThumb and MoveThumb is not in your code so I cannot compile. Anyway, it is not the problem.
Anyway, can you clarify more details about "it only crops an image when user draws the rectangle and not when moved or resized", it is already normal behavoir for you to draw a rectangle and then move it. What kind of action do you want? Do you
mean some controls like this:

Moving and resizing shapes .?!

hey there ..
i was wondering if you guys can help me figure out how to select , move and resize a specific shape .... apreciatte it a lot .. peace . take care and thanks for your concerns..

Hi there, take a look at this code:
http://forum.java.sun.com/thread.jsp?forum=31&thread=427823
You can view the working version at www.bhun.net/shapebean.html. The example isn't very complicated nor does it contain much functionality. But it does show you one way to handle the shapes (there are probably better ones). Resizing a shape just requires you to do some extra work.

Moving and resizing fields

Hello,
1. I want to make a field just a little bit smaller but when I grab the grab bars and drag to make it smaller it redcues it too much. How do I drag it very, very small amounts? I have looked for help topics on this and there is nothing. I have tried holding down ctrl, alt, and shift when I drag but nothing does it.
2. How do I get a field to just nudge a little with arrow keys?
Thank you.

I use the Layout pallet to position object quite a bit. How ever I do use the arrow keys to nudge objects around the page. You might check and make sure that Snap to grid is unchecked otherwise when you use the arrow keys to move objects they will move in the increment the grid is set to. To set the grid or define grid and ruler settings and guides go to Windows -> Drawing Aids. I think snap to grid is checked by default.

Use of Java Swing +Applescript to move and resize Mac OS X windows using

Here is an interesting use of Java on Mac OS X and Applescript to
enable moving and resizing of windows using mouse and keyboard:
[MoveResize tool|http://code.google.com/p/sandipchitalesmacosxstuff/#Move_and_resize_windows_on_Mac_OS_X]
How it works:
The implementation uses Applescript to get the front most window and
it's bounds. It sends the bounds rectangle to a server implemented in
Java over a socket connection. The Java server takes the screen shot
of the full Desktop and uses it as the Image label (a JLabel with
ImageIcon) as the content pane of an undecorated JFrame which has the
same bounds as the Desktop. A JPanel with semitransparent background
and a dark rounded rectangular border is given the same bounds that
were received over the socket. This JPanel is added to the
PALETTE_LAYER of the JFrame's layered pane - which makes it appear
floating in front of the front window. A Mouse and a Key listener
added to the JPanel allow moving and resizing of the JPanel. When the
user types the ENTER key the JFrame is hidden and the new bounds of
the JPanel are sent back to the Applescript over the socket connection
which moves and resizes the front most window.
Enjoy!

Copy the /Home/Documents/ folder to the NAS drive. That drive needs to support AFP or you may run into filename problems and/or other file related problems due to filesystem differences.
Once the folder has been moved to the NAS select the folder on the NAS and CTRL- or RIGHT-click. Select Make Alias from the drop down menu. You should now have an alias named "Documents alias." On the Mac put the /Home/Documents/ folder in the Trash but don't delete it. Copy the alias file from the NAS to the /Home/ folder. Rename it to simply "Documents." Double-click on it to be sure it opens the folder on the NAS. If so you can empty the Trash. You're done.

Adobe Air is very smiller than Zinc App - Reposition and Resize not working?

Hello guys, i have found and readden nice solution like NativeWindow was saved positions and sizes If i close Adobe Air App and i open again like NativeWindow was moved and resized. It is very simple working. And it works fine. 100 % Good! But how does it work with Zinc App because it doesn't work for positions and sizes. How do i fix? I have upgraded code from FileSerializer.as With mdm.Script:
package
import flash.events.Event;
import flash.net.URLRequest;
import flash.net.URLStream;
import flash.utils.ByteArray;
import mdm.Application;
import mdm.FileSystem;
import mdm.System;
public class FileSerializer
public static function WriteObjectToFile(object:Object, filename:String):void
var fileExists:Boolean = mdm.FileSystem.fileExists(mdm.Application.path+filename);
var outByte:ByteArray = new ByteArray();
outByte.writeObject(object);
if(fileExists == false)
mdm.FileSystem.saveFile(mdm.Application.path+filename, "");
mdm.FileSystem.BinaryFile.setDataBA(outByte);
mdm.FileSystem.BinaryFile.writeDataBA(mdm.Application.path+filename);
private static var stream:URLStream;
public static function ReadObjectfromFile(filename:String):Object
var fileExists:Boolean = mdm.FileSystem.fileExists(mdm.Application.path+filename);
if(fileExists == false)
var obj:Object;
stream = new URLStream();
stream.addEventListener(Event.COMPLETE, function(evt:Event):void
obj = stream.readObject();
stream.close();
stream.load(new URLRequest(filename));
return obj;
return null;
That is improved to mdm.Script and it saves sometimes.
And i have create UserPref.as
package
public class UserPref
public var zincForm:String = "MainForm";
public var zincType:String = "sizeablestandard";
//public var zincSWF:String = "MainApp.swf";
public var zincPosX:Number;
public var zincPosY:Number;
public var zincWidth:Number;

Can Effects etc. windows be moved or resized?

The effects window is a little small and claustrophobic even on my 24" display.
Can it be moved and resized?
Also is there any PDF version of the Help Manual available?

I have discovered how to download a PDF Help Manual:-
1. Go here http://help.apple.com/finalcutpro/mac/10.0/
2. Click on the printer icon in the top right corner and select "Book".
3. In the printer window click the "PDF" button and select "Save as PDF".
I would still like to know about repositioning and resizing windows.

Photoshop CC: Have a template that I moved image into. Image is too small. How do I resize the image while in the template? Or must I go to original image file and resize there again and again until I get the right fit?

I have a template that I am able to plug different pictures into at different times. The problem is that when I plug an image into that template, I find that the image is either too big or too small. Is there a way to plug the image into the template and resize the image (and not the template itself) OR will I have to go to the file with the original image and resize it there and then try to plug it in to the template to see if it fits------and if it does not fit, go back to the original file with the image and resize it again and see if that fits---and so on and so on...........? I have tried the" image size" option but it's hit or miss------mostly miss!
Thanks!

Read up on Smart Objects. It looks like you have no idea as to how to create and use them.
Jut create a Smart Object from the layer containing whatever it image it is that you are "plugging into your template". But you do need to learn the application at its most basic levels.
Photoshop is a professional level application that makes no apologies for its very long and steep learning curve. You cannot learn Photoshop in a forum, one question at a time.
Or is it possible that you don't even have Photoshop proper but the stripped-down Photoshop Elements?"
If the latter is the case, you're in the wrong forum. This is not the Elements forum.
Here's the link to the forum you would want if you're working in Elements.:

If you do have Photoshop proper, please provide the exact version number of that application and of your OS.

Moving and properly placing fields in a FormsCentral form

I've just started using this software that came with Acrobat XI and began designing a form from scratch. Moving and placing fields in your desired location seems to be quite challenging unless there is something I do not understand about the process. The primary annoyance is when using the left side handle to change the width of a field, all other fields above appear to be connected and all change widths together. Also, moving a field along a horizontal plane always ha sthat field snap back to its original position. Any help here?

All th fields in the first column in FormsCentral share the same label width. You might want to try to put the label on top if you don't like this behavior.
If you insert fields on the right on a form element then you can independently set its label width.
You can only put a form element next to another one. If you want more horizontal "spacing" between element you can resize it by increasing the previous element width. In the image below you can see what you need to "drag"to increase spacing.
Hope this helps

Grouping and resizing screen controls

The manual says this:
To group screen controls:
1 Select the screen controls you want to group together.
2 Choose Group from the workspace Action menu (or press Command-Option-G).
The screen controls are grouped. Moving one of the grouped controls moves the
others, and resizing one of the grouped controls resizes the others.
However, when I try that and then try to resize a group, only the control that I'm resizing actually resizes. Can someone else try this and then point me to the stupid thing that I'm missing?
yes, all the controls (9 sliders, 8 buttons, 8 knobs) are "merged" before "grouping"
Thanks,
Stewart

Make sure that you do not run Firefox in full screen mode (press F11 or Fn + F11 to toggle; Mac: command+Shift+F). 
If you are in full screen mode then hover the mouse to the top to make the Navigation Toolbar and Tab bar appear. 
You can click the Maximize button at the top right to leave full screen mode or right click empty space on a toolbar and use "Exit Full Screen Mode" or press F11.

What is the best way to move and resize layers?

When I click on a layer to move and resize it in Elements 8 in Windows 7, it disappears. After I go to Edit/Undo, it reappears. What should I do?

I have PSEv.8 and Windows 7, and the Editor works like a charm for me.
Try the following:
Open picture 1, duplicate the background layer.
Open picture 2, make a selection of something in the picture with one of the selection tools, and then go to Edit>copy. This puts the selection on the clipboard.
Go back to to picture 1, go to Edit>paste, and the selection will be on its own layer
Use the move tool to position and resize the selection.
The middle layer can be dragged to the top. Here, this process will obscure visibility of Layer 1, but you can drag the layer structure back, of course.
http://www.pixentral.com/show.php?picture=1D3wrzjD5r24U8LfdTA1sdUb0zJOY0
I opened a picture of the house on the lake, copied/pasted the "Slick Rock Divide" sign as per above. The layer structure is represented in the print screen.
You should note that it is best if the resolution of the picture files is the same, or close to it.

When I try to open any kind of links, the page first shows me "the document has moved" and then goes on to some advertisement page.

When I follow any kind of links or try to open something in another window or new tab, the browser first shows the white page with text "the document has moved", and then moves to advertisement page of some sort. Usually in the small box where the page description is it says "Jump". I don't know how to disable it, it is really irritating.
