IMovie 11 picture box layouts

Can you alter, or create your own photo box layouts in iMovie 11. If so how, or where can you do this.
I can't find that option. I don't want to use the canned, preset photo layouts. Any options available?

It has been happening to me, but it doesn't change the final video itself, if it is previewed in full screen mode, it will sometimes freeze, but to see the scene that freezes, just play it (in fullscreen mode) and click back a few seconds before it freezes and it should play normally.
You can also bring the mouse over the clip to preview it or:
Duplicate the whole project
2. Export it to Quicktime
Hope this helps

Box Layout problems

Hello,
I am having difficulty with my box layouts in my form applet.
I have a JFrame with two panels. The left panel will allow the user to enter some parameters via text boxes, drop down menus, etc for a shape, which will appear on the right panel.
To arrange the form entry boxes on the left panel, I implemented a box layout. Here is where my trouble lies. I am not sure if I am using them correctly.
In the left panel, I added a box objectentitled entrySideBox, which has a createVerticalBox() orientation. I further added 7 boxes to this box layout, which had a createHorizontalBox() orientation. I have the form elements within the array of horizontal boxes. In summary, I hoped to create a box layout column with 7 horizontal rows to house the form entry elements.
Can I do this with the Box Layout? My form elements do not appear to be appearing as expected!
I have my code below. What is wrong?

The problem with GridLayout is the form elements sizes
change relative to the size of the panel. I want the
form elements to remain in a consistent state.
Should I quit using the box layout?Ok, try to set the layout of the upper content pane to BorderLayout and place the left panel with your components in the WEST part of it (the panel for the drawings goes to CENTER). I don't know if this will produce the result that you want, but it's an idea.
You should use a GridLayout for this panel and only
specify 2 columns (don't specify the number of rowsor
the number of columns will be ignored, see theclass
documentation for further details).
Hope this helps,
Pierre2 Columns? For what?The first column is for the labels (e.g. "Select Font Color") and the second is for the input component (e.g. textarea).

Box layout help

i know how to use a box layout on panels but i am having a problem applying box layout on jframe,
what i do basicaly is extends jframe first and then in the constructor i put setLayout(new BoxLayout(this,BoxLayout.X_AXIS));
it gives an error that box layout cant be shared...this method works with all other layouts...
please help me and please dont tell me to go read the sun online tutorials...

To speak truely. All the j2se default layout manager will be replaced by the default layoutmanager in NetBeans ---group layout manager.
I suggest you download a NetBeans IDE and start working with the new layout manager.

How to have a box layout on a JDialog, with an image set as background

Hi,
I need to have a JDialog in which there is a background image set (I already did this part, but only with the default layout). I further need to add text to the lower part of the JDialog. (For this, I guess I need to have a box layout.). I am not able to do so, because if I do so, I wont be able to set image background to the entire JDialog. Please help me out with how to solve this issue?
Thanks,
Joby

Hi jduprez,
Thanks for the reply. I checked Rob Camick's blog. It gives a nice way to add an image to a panel (*master panel*) and to use it.
I still have my problem open. The above solution gives panel that I can add to my JDialog. But on the bottom half of the image (as you said, BorderLayout.South), I need to add another structured set of components using a Border Layout again.!, ie, one more panel with a BorderLayout. So when I add
this panel, to the master panel containing the image, then the image gets cut off, at that point. I tried using component.setOpaque(false) on my sub-panel, still it does not work. Any idea, how to achieve this...?
Following is the code I have adapted.
public class BackgroundPanel extends JPanel
 public static final int SCALED = 0;
 public static final int TILED = 1;
 public static final int ACTUAL = 2;
 private Paint painter;
 private Image image;

 JDialog dlg = new JDialog();
 dlg.setLayout(new BorderLayout());
 dlg.add(panel);
 panel.setTransparentAdd(true);
 Panel nPanel = new Panel();
 nPanel.setLayout(new BorderLayout());
 JLabel label = new JLabel();
 //label.set
 label.setText("<html>HI This is another line </html>");
 nPanel.add(label, BorderLayout.NORTH);
 panel.add(nPanel/*label*/,BorderLayout.SOUTH);
 dlg.setSize(600, 500);
 dlg.setVisible(true);

 File file = new File(fileName);

 try{
 image = ImageIO.read(file);

Using box layout?

Hello,
I wondered if anyone could advise? In this code I was trying to display a column of buttons each the same size. And next to these buttons, a single button, and textfield.
Something like:
Button 1
Button 2
Button 3 "some space" SearchButton ////Text field ///
Button 4
Button 5
But when the textfield is displays it becomes the height of the 5 buttons, but the searchbutton did not. Is there any method to change the textfield to the height of the searchButton? Or could anyone possibly demonstrate a different layout manager?
Thank you
JButton button1, button2, button3, button4, button5;
JPanel panel = new JPanel(new GridLayout(0,1));
panel.add(button1 = new JButton("Button 1"));
castleGreen.addActionListener(this);
panel.add(button2 = new JButton("Button 2"));
runTown.addActionListener(this);
panel.add(button3 = new JButton("Button 3"));
highHill.addActionListener(this);
panel.add(button4 = new JButton("Button 4"));
luckNow.addActionListener(this);
panel.add(button5 = new JButton("Button 5"));
littleHaven.addActionListener(this);
Box leftCol = Box.createVerticalBox();
leftCol.add(panel);
Box rightCol = Box.createHorizontalBox();
rightCol.add(searchBt = new JButton("Search"));
searchBt.addActionListener(this);
rightCol.add(Box.createHorizontalStrut(10));
rightCol.add(searchTf = new JTextField(20));
Box topDisplay = Box.createHorizontalBox();
topDisplay.add(leftCol);
topDisplay.add(Box.createHorizontalStrut(40));
topDisplay.add(rightCol);

Thank you for replying.
In my version of the code the name shown on the left
buttons are all differenet sizes. When I built these
into a vertical box, the buttons were displayed
uneven. I resolve this by using a panel.By default the system sizes buttons according to the ammount of text in them.

I wondered to achieve this layout, would be easier to
use a gridbaglayout?Personally I've gone right off GridBagLayout. It's complicated to use and seems unstable in resizing.
I've got much more reliable results from BoxLayout.

How to center Text Box on Web Page? -- Web dev with Word 2013

I'm trying to assist a user who wants to use Word 2013 for simple web page development.
There are many tools but they want to use Word 2013.
Actually have it working by saving the Word 2013 files as web pages... like index.htm, about.htm, etc.
The problem is when we use the "Insert" tab in Word to create a "Text Box" or a "Shape" ...
And align it centered on the page... it looks fine in Word but when we open it with a web browser the "Text Box" or "shape" are no longeer centered.
We thought we had it fixed by making the "Text Box" Layout Options "In Line with Text" but again... looks fine in Word but not in a web browser.
The question: How can we get a "Text Box" in Word 2013 to appear centered on a web page?
thanks for any help.

Hi:
For webpage design, I would suggest customized form under develop tab on the Ribbon over insert object directly. I tested from my side, using customized form will lock the object position on the
page.

Cannot save Crystal report layout or view new layout of report

I am trying to make a change to a system crystal report (cust. recievables detailed aging). I had to make the date feild a little wider, so I edited the "system layout" that came with SAP (in my test DB of course), and I go to add-ins>sap business one>save. I get the following error "current user has no permissions for this operation". I am logged in as a superuser and full perm.
If I "save-as" and save it to a layout in sap....when I go to open the aging with my newly created layout it freezes and asks for DB logon info to connect to my server from crystal. I do not normally have to do this when I preview my reports in the out of the box layouts. WHat am I doing wrong? I am new to crystal.

The system will not allow me to export the system crystal report....it is grayed out, and it IS a crystal report. HOwever I can open it in crystal, then save it to my desktop, then from INSIDE of SAP in the report and layout manager I import the crystal report I made the changes to from my desktop into SAP and it saves and imports no problems. However when I go to view the report (and this is only the ones I import), it prompts me with the db login for our server to connect, and it is only with that report, once I enter sa credentials it is fine and shows up from there on in, but not if I log out of SAP and back in...then I have to put in my credentials again. Is this something having to do with the report when I make changes to it? I cant have users entering login info each time they run the new aging details report. Please advise what I may be doing wrong when I make changes to a crystal report. It was a very minor change....just moved a feild width.

Custom Report layout

I have a simple question to ask (simple I hope a tleast). In the past, I have been able to use the out of the box layout for most reports. However at my current job, we will be needing some custom layouts done to the report region to show parent child style reports.
I know that the region is just HTML with some CSS thrown in along with placeholder columns, but am confused as to if I can get the formatting to look like this:
Name ID # DOB Race Office Location (Parent row of data)
Appt Loc Appt Date/Time Appt Descript Appt Meet With (Child Row)
Where there will be a number of child rows per employee. I could do this manually (HTP.p processing), but would prefer to have the pagination and other features the product provides.
Can any suggest a solution here?
Thank you,
Tony Miller
UTMB/EHN

Guess I will look at customizing the HTML layout, or doing it via htp.p output. My main goal is getting reports for the users, and it works well with the PDF out option with BI Publisher..
Thank you,

Flex-box model not correctly implemented in Dreamweaver CS5.5, pleas improve!

Hi all,
there is a good introduction to: Flexible Box Layout module
see: http://www.css3.info/introducing-the-flexible-box-layout-module/
I tried the same example in my new Version of Dreamweaver CS5.5
--> surprise: Dreamweaver CS5.5 cannot show in a correct manner a following div:
<div class="flex_box flex_stretch flex_vertical">
where css are:
 .flex_box {
 background: url('./img/box-model.png') no-repeat center center;
 height: 180px;
 margin-top: 16px;
 width: 180px;
 .flex_stretch {
 display: -moz-box;
 display: -webkit-box;
 display: box;
 -moz-box-align: stretch;
 -webkit-box-align: stretch;
 box-align: stretch;
 .flex_vertical {
 -moz-box-orient: vertical;
 -webkit-box-orient: vertical;
 box-orient: vertical;
CS5.5 can only strech in 1 direction, when shown as in a browser (German "ENTWURF").
In Firefox, sam is ok:
I need a correct representation of these boxes, when will there be an improvement??????????

John,
I misundrstood you response
I entered http://localhost in my browser and recieved the following page:
Asd you can see everything is working. I thought that when you called local host, it went to the www/ directory where I have my sites
I still don't see a problem with my settings
Server Folder: C:\TNG813onMowesII\www\
Web URL: http://localhost/genealogy/
I hate it when the tool is more trouble than the work.

Determine the best width for ListCellRenderer - Multi-column combo box

Currently, I am having a multi column combo box. In order for the column to align properly during show popup, I use box layout to do so. However, the short coming for box layout is that, the size for each column is fixed. This makes me have a difficulty, when I have a long string to be displayed. The problem is shown through the following screen shoot.
http://i.imgur.com/4Nfc6.png
This is because in 2nd column,
1) All the 3 rows must be in same size so that they are aligned.
2) But 1st row and 2nd row cell renderer, do not know 3rd row is holding such a long string.
The code (2 files) to demo this problem is as follow. Is there any way the size of the cell will be adjusted automatically? Yet, all the row will be aligned properly.

Are these two lines intentionally or is it just a mismatch?
jLabel2.setMaximumSize(new java.awt.Dimension(100, 14));
jLabel2.setMinimumSize(new java.awt.Dimension(200, 14));
2) But 1st row and 2nd row cell renderer, do not know 3rd row is holding such a long string.There is only one cell renderer for all rows, so no need for the rows to know each other.
To calculate the exact maximum width of column two, you have to check each entry.
If you can do this BEFORE creating the combo, you could do this in a loop similar to this pseudo code
FontMetrics fm= jComboBox1.getFontMetrics(jComboBox1.getFont());
foreach (column2String) {
int length= fm.stringWidth(column2String);
if (length>max) max= length;
}Now you have a max value to dimension jLabel2 in your renderer.
If you don't fill your combo in one go, but rather at runtime, you have to check at each
jComboBox1.addItem(...)
whether the string for label2 is extending the current max, redefine max, and repaint the combo.
This second approach I haven't done so far, but that's how I would try.
