How to display subtitles over videoComponent from getVisualComponent - JMF

I'm writting video player and I have encountered a problem. Is there a possibility to add Component (or something else what could display text in) to Component that I got from JMF method getVisualComponent(). As this method returns Component I can't add subcomponent to it. I tired to add recived Component to LayeredPane and JPanel with subtitles to higher layer of LayeredPane, and it works if I force lightweight renderer. But I'd like to use OpenGL renderer (com.omnividea.media.renderer.video.OpenGLRenderer), and in this case I've got black background in topmost layer with subtitles (even with setOpaque(false) ). Is there possibility to display one Component over another Component (top most component should be with transparent background)?
ps. If video is rendered by open gl renderer it is possible to draw with open gl in Canvas (instead of GLCanvas)? Precisly I've got HeavyComponent from getVisualComponent() that is subclass of Canvas.
ps2. Or how to tie my component1 to component2 in a way that component1 gets paint event when component2 gets paint event or when component2 is repainted?
ps3. Ok I figured out that problem with black background is thanks to havyweight component. If I add some component (lightweight component) on GlassPane it is above all lightweight components and below all heavyweight components. So is there a way to add lightweight component above heavy weight component in a way that lightweight component have transparent background?

Gosh, talk about a confusing mess of questions...
Heavyweight components will not go behind lightweight ones, which is why it's bad to mix heavy & lightweight components.
And yes, you can draw on the video inside whatever is rendering the video. You'd just, essentially, draw the image and then draw whatever you want on top of the image.
I'd point you to the following thread to read:

How to display a new view from a nib ?

how to
display a new view from a nib in the main window after clicking on a button.
When I click a the button named for example "goToGokyo", the link to my procedure
runs correctly because I see my NSLog message "goToGokyo button pressed".
My nib, which name is "GokyoViewController" does exist.
I did as follow for the moment but I'm stuck now, my nib :
- (IBAction)goToGokyo:(id)sender
    NSLog(@"goToGokyo button pressed");
//[self stopSound];
if (gokyoViewController == nil)
        GokyoViewController *aGokyoViewController = [[GokyoViewController alloc]
                                                     initWithNibName:@"GokyoViewController" bundle:nil];
        self.gokyoViewController = aGokyoViewController;
        //[aGokyoViewController release];
    [self GokyoView:gokyoViewController animated:YES completion: nil];
Thanks in advance for your advice.
Cheers

I did that now :
- (IBAction)btnLoadMyViewController:(id)sender
    NSViewController *viewController = [[NSViewController alloc] initWithNibName:@"MyView" bundle:nil];
    NSView *view = [viewController view];
    [_myWindowController.window setContentView:view];
    //view addSubview:view];
    //[self.myView addSubview:view];
Using
"_myWindowController.window setContentView:view];"
or
"[self.myView addSubview:view];"
does not an error but does nothing !
Would you help me one more times please ?

How to display a oracle table from a java program?

How to display a oracle table from a java program.
Hello friends, I have written a Java program, using oracle 10g as backend.
I want to display a oracle table as output. Im not getting how to display oracle table as a output table.. Pls help me
Thank you

jayanthds, you're not going to get a satisfactory
answer to this here. it's too big a task to justbe
quickly outlined in a forum - the reply "all youneed
to do is to query you table and return it asJTable"
is worthless, for example, since the solution to
any problem can be distilled to such a
soundbite, if need be. doesn't make the solutionany
simpler
essentially you're asking "how do I write adatabase
application?". all you'll get is snippets of code
that, when fitted together, will eventually helpyou
do this, but you'll spend days and days comingback
saying "right, I've done that, now what?" until
either you or the forum gets frustrated with the
whole affair and the process stops
there are entire books written about this subject,
and countless tutorials and guides on theinternet.
you're better off going down that routehehehe.well, it's true! I used to have a manager that would outline the solution to a problem in a few lines of pseudocode, and then firmly believe that the actual solution would be just as brief and simple. shame his pseudocode included such lofty abstractions as "reformat all data"

How to display all tagged photos from the whole catalogue?

Hi,
I have been googleling around, but have not found the right information. I am trying to find all my tagged photos of all imported photos, but it would only show the tagged photos from a specific folder when I select that specific folder or from the timeline, in which I already knew that some tagged photos belong in those folders.
My question is...how can I search tagged photos from the whole catalogue without going through the timeline or clicking each folder and subfolder to view them. I would like that the organizer display all tagged items from all my folders and subfolders at once.
Sorry if this has been answered and I was not able to find the right forum or information.
Many thanks in advance!

How to display a javafx window from a java program?

hello,
I found in the help how to call a java class from a javafx class, but how can I do the opposite : make a javafx window visible and active from a java class (main method e.g.)?
thank you,
olivier.

I haven't studied the topic, but I stumbled upon a good number of threads and blog articles on how to use JavaFX in Swing...
Basically it is hackish (might depend on current implementation, thus break on new releases) because Sun didn't designed it for this task.

Used my now ex's iMac and some of her music to start up iPhone 4 and backing up as well, but after break up, getting anther chance to update was out of question how can I transfer over 2000of3900songs from her Mac to my PC not using her computer or Apple

I have over 4000 songs from mine and my now ex gfs Mac. After the split I was unable to transfer her share of music to my new lab-top. I don't wanna lose my music but I can't buy all music again I've had this problem for so long. My iPhone hasn't been backed up or synced since May 2013 I don't wanna download illegals just to get music. I figure if it's in my phone now why take it off to put back in. iTunes or Apple needs to fix the sync process or allow tranfer of music files from Iproducts directly to the computer if I back it up will it transfer all music or is this a lost cause.

Now all my new apps as well as several others are gone from the iPhone.
Look on other screens. The 4.1 update ands Game Center to the home screen. If that screen was full it create a blank screen and moves one app from the home screen to the new screen to make room for Game Center. All the other screens are pushed back one place.
How can I get my apps back? It cost me a lot of time and money to discover those apps and get them onto the phone. Are they just gone now?
If they are really gone, you can download them again. You will not be charged again if you use the same iTunes account.

SSRS - How to display all the results from a query and then be able to filter the data

Let's say I have a simple query that will return products name, ID, price
SELECT pname,
pID,
price
FROM products
When I display the results in SSRS the user will (without entering any parameters) see something like:
Product Name | ID | Price
xyz 1 $10.00
.zzz 10 $4,000.00
How can I filter my results once they are displayed? For instance, Out of the results the user wants to see only the products where price is between $10 and $3000?
-Alan

Hi Visahk,
Maybe I did not explain my issue very good.
I want the user to first see all results (without entering the price range) - then if he wants she/he can filter the results by price.
As soon as I add
WHERE price BETWEEN @StartPrice AND @EndPrice
to my SQL query, the user is prompted to enter a price range before seeing any data.
-Alan
Ok for that what you can do is to set allow null value property for the parameters.
Then set NULL as default value for parameters in parameter properties tab
and make the query as below
WHERE price BETWEEN @StartPrice AND @EndPrice
OR (@StartPrice IS NULL AND @EndPrice IS NULL)
and then report will get executed without waiting for any prompt and user may change values at a later stage and rerun it
Please Mark This As Answer if it helps to solve the issue Visakh ---------------------------- http://visakhm.blogspot.com/ https://www.facebook.com/VmBlogs

ADF-BC/JSF How to display acustom error message from a backing bean

Hi all
Can anybody provide an example of how to manipulate the list of error messages from a JSF backing bean.
In my code I use a different navigation case and this directs the user to the page displaying the error message but I am sure that there must be a more elegant way.
Thanks in advance
Thanassis

Thanks Kris
I think you 've put me on the right track here, it's just that in my case what I really want to do is prevent my users from editing records not belonging to their own group. This is done via a selectOne table component and then the backing bean code tests if the value #{row.UserGroup} matches the #{bindings.LoggedOnUserGroup.inputValue}. If the values are equal then the beans returns the navigation case to the edit page. Otherwise it returns the navigation case for the "cannot edit" page.
So what I am thinking is to return null and somehow raise the right kind of exception in order to display the error in the af:messages tag.

How to display all items titles from custom list with checkbox to select for each user

Hi All,
I have a requirement in a sharepoint 2013 development project.
A custom list items will be created by admin with the following columns:
Title
Hyperlink
User business unit (This column which is a metadata will be a userprofile property)
In a page/form I have to display the list of titles with a check box based on each user business unit and each user will be allowed to check the list of titles and hit save. And then have to display the list chosen by the user in a webpart.
If they want to modify their list they have to go to the page/form again and will uncheck the list.
Am not sure whether I can achieve this through sharepoint out of box feature, I have not done any custom development.
Please provide your valuable suggestions/ideas on this. Thanks for looking on this !!!

Hi,
Per my knowledge, there are no such OOTB features can meet your requirement, however, there is a workaround that if you can modify your requirement a bit.
Based on your description, you want different users be able to select values from a list and generate a list own by them.
If this is what you mean, we can do it like this:
1. Create another list "Users" which stores the names of every users;
2. Create a list "Result" which will be available for every user to add their own items, this list will have four Lookup columns and they look up to the "Users" list and the
list you mentioned before;
3. Users can add items into "Result" list by selecting the needed values from the other two list, then the items he/she created will be connected to them with the help of the
Lookup column which looks up to the "Users" list.
4. You can take use of the OOTB permission management of list to control the access of each item in the "Result" list, and it will be easier for you to manage and filter the
information you needed.
