Scalable UI?

This has probably already been discussed but my searches didn't turn anything up.
I'm trying to figure out how to implement a JFrame with scalable components. What I mean by this is when the window is re-sized by the user, I want certain components to stretch, and others to maintain certain widths, but perhaps stretch height. So let's make a simple example. Lets say I had a JFrame that had a list of buttons on the left in a column and each button I pressed displayed a story on the right. I'll [attempt to] draw in ASCII art.
|  butt1  |   Once upon a time.. blah blah blah   |
|  butt2  | This is more of my story. Then my     |
|  butt3  | story ends here                       |
|  butt4  |                                       |
|  butt5  |                                       |
|  butt6  |                                       |
---------------------------------------------------For instance for a JFrame containing elements like this, it would be really nice if I could say, when the screen is re-sized, don't stretch the "button margin" horizontally, but do expand vertically. With the story pane on the right, then when the JFrame was re-sized horizontally, it could save all the horizontal space for more story - like this:
Horizontal scaling:
|  butt1  |   Once upon a time.. blah blah blah  This is more of my story. |
|  butt2  | Then my story ends here                                        |
|  butt3  |                                                                |
|  butt4  |                                                                |
|  butt5  |                                                                |
|  butt6  |                                                                |
----------------------------------------------------------------------------Vertical scaling (more buttons displayed):
|  butt1  |   Once upon a time.. blah blah blah   |
|  butt2  | This is more of my story. Then my     |
|  butt3  | story ends here                       |
|  butt4  |                                       |
|  butt5  |                                       |
|  butt6  |                                       |
|  butt7  |                                       |
|  butt8  |                                       |
---------------------------------------------------This was probably longer than I needed to make the explanation but I think it makes it clear. Thanks in advance for anyone reading this far.

For the particular case you describe, you want BorderLayout . The "button" section would be in BorderLayout.WEST (or BorderLayout.LINE_START if you want to be l10n-proof).
I suggest you read through [Using Layout Managers|http://java.sun.com/docs/books/tutorial/uiswing/layout/using.html] . The learning curve is steep, but well worth it.

  • Difference between scalable and failover cluster

    Difference between scalable and fail over cluster

    A scalable cluster is usually associated with HPC clusters but some might argue that Oracle RAC is this type of cluster. Where the workload can be divided up and sent to many compute nodes. Usually used for a vectored workload.
    A failover cluster is where a standby system or systems are available to take the workload when needed. Usually used for scalar workloads.

  • How to make scalable text button

    I'm learning Captivate at the moment and I cannot understand this at all...
    I want to creat a text button. Captivate allows NO options to change the grey text box or blue rollover effect. So I find out that the only way to do it is to creat your own image button, BUT Captivate does not allow Illustrator import, thus the images are not scalable. This means that if I want to creat a text button that will have various sizes of widths the image will have to be stretched and this looks awful.
    Someone please tell me that my only option is to not create a seperate image for every instance of text due to variance in width.......
    Please help.
    I tried calling the Adobe Technical Support line... I even spoke with a specialist. They did not speak English well and kept telling me over and over to import my own image... but that does not solve the problem, it still stretches!!! They basically said there is no way around this. I cannot believe this to be the case... Even powerpoint allows text button customization....
    Thank you

    The look and feel of the default text button object in Captivate is actually controlled by your operating system.  So if you look at the same course onh a Windows 2000, Windows XP, and Windows 7 box, the buttons will all look slightly different.   This is one reason that Captivate gives you the option to use other button types such as image buttons, which you can also create for yourself if you are handy with an image editor.  There is currently no import facility for vector art from Illustrator or other similar programs.
    Since the OS controls the default text button appearance, you don't have a lot of control over things like the corner radius etc, because in the OS, this might actually be square (e.g. in Win2000).
    It sounds more to me like what you REALLY want is to be able to use some of the Captivate text caption types as if they were buttons.  Some of these have rounded corners.  Alternatively, you can create a rounded rectangle using the drawing tool and configure the corner radius and background colour any number of ways.  The only things you'd be missing are rollover effects (doable with rollover captions) and interactivity.  Lilybiri suggested that you can just place an invisible clickbox over the top of the caption to make it work like a button.  The user will never know that it's the clickbox instead of the caption that they're clicking.
    If you want even more options as far as interactivity triggered by other mouse events such as mouse over and mouse out, you can make almost any Captivate screen object interactive using the Event Handler widget from Infosemantics.

  • External memory allocation and management using C / LabVIEW 8.20 poor scalability

    Hi,
    I have multiple C functions that I need to interface. I need
    to support numeric scalars, strings and booleans and 1-4 dimensional
    arrays of these. The programming problem I try to avoid is that I have
    multiple different functions in my DLLs that all take as an input or
    return all these datatypes. Now I can create a polymorphic interface
    for all these functions, but I end-up having about 100 interface VIs
    for each of my C function. This was still somehow acceptable in LabVIEW
    8.0 but in LabVIEW 8.2 all these polymorphic VIs in my LVOOP project
    gets read into memory at project open. So I have close to 1000 VIs read into memory when ever I open my project. It takes now about ten minutes to
    open the project and some 150 MB of memory is consumed instantly. I
    still need to expand my C interface library and LabVIEW doesn't simply
    scale up to meet the needs of my project anymore.
    I now
    reserve my LabVIEW datatypes using DSNewHandle and DSNewPtr functions.
    I then initialize the allocated memory blocks correctly and return the
    handles to LabVIEW. LabVIEW complier interprets Call Library Function
    Node terminals of my memory block as a specific data type.
    So
    what I thought was following. I don't want LabVIEW compiler to
    interpret the data type at compile time. What I want to do is to return
    a handle to the memory structure together with some metadata describing
    the data type. Then all of my many functions would return this kind of
    handle. Let's call this a data handle. Then I can later convert this
    handle into a real datatype either by typecasting it somehow or by
    passing it back to C code and expecting a certain type as a return.
    This way I can reduce the number of needed interface VIs close to 100
    which is still acceptable (i.e. LabVIEW 8.2 doesn't freeze).
    So
    I practically need a similar functionality as variant has. I cannot use
    variants, since I need to avoid making memory copies and when I convert
    to and from variant, my memory consumption increases to three fold. I
    handle arrays that consume almos all available memory and I cannot
    accept that memory is consumed ineffectively.
    The question is,
    can I use DSNewPtr and DSNewHandle functions to reserve a memory block
    but not to return a LabVIEW structure of that size. Does LabVIEW
    carbage collection automatically decide to dispose my block if I don't
    correctly return it from my C immediately but only later at next call
    to C code. Can I typecast a 1D U8 array to array of any dimensionality and any numeric data type without memory copy (i.e. does typecast work the way it works in C)?
    If I cannot find a solution with this LabVIEW 8.20 scalability issue, I have to really consider transferring our project from LabVIEW to some other development environent like C++ or some of the .NET languages.
    Regards,
    Tomi
    Tomi Maila

    I have to answer to myself since nobody else has yet answered me. I came up with one solution that relies on LabVIEW queues. Queues of different type are all referred the same way and can also be typecased from one type to another. This means that one can use single element queues as a kind of variant data type, which is quite safe. However, one copy of the data is made when you enqueue and dequeue the data.
    See the attached image for details.

    Well, anything with "Demo" or "Source" in the title you can delete usually without any problems.
    It looks like everything in your list is X11 related. Its really a question for you. If you plan to perform TOTAL CLI type administration on this machine, you can delete the X11 stuff completely. This of course assumes there in nothing in the SunONE application software suite which doesn't require X11 capabilities for configuration. I've never used the SunONE app server but I SERIOUSLY doubt it does. More then likely its administration is browser based.
    BUT, if you want to perform some limited X11 display back stuff from time to time, you're going to need the X11 stuff.

  • Scalable Apache service in a zone cluster

    Hi,
    I have set up a 2-virtual node zone cluster (on a physical 2-node cluster).
    I am trying to set up an apache resource group (scalable) on the two nodes, but I don't get the zone cluster nodes as valid options to use while running clsetup and/or the web gui wizard.
    They only see the two global zones and one failover zone I have configured on the cluster.
    Is there no way to set up a scalable apache service on the zone cluster? Any help will be appreciated.
    Thanks,
    D

    Never mind...I had to run the clrg,clrs and clressharedaddress commands from within the zone cluster nodes and not from the global.
    It's going to take a while to come to terms with the clustering within the cluster.

  • Best practice for application module  for scalability

    if i compare application module with forms 6i runtime session.(correct me if i wrong)
    In forms 6i, we create for single form for purchase entry. in which we select table like po , po_item, item_master, customer master
    also single form for sales entry. in which we select table like sales , sales_item, item_master, customer master, po , po_item
    So my question is. in jdeveloper , we planning to make separate jsp page and applicaiton module for purchase entry,
    separare jsp page and application module for sales.
    is it ok.
    or
    what is the best practice in this senario.?? ( or in scalability senario)
    if i made one single application module for whole application (let say 300 entity's(tables)) will performance of my app server degrade.

  • Scalable graphics problem

    b Please note:
    Im not sure whether this problem is related to Illustrator itself, but I would greatly appreciate the help of anyone more enlightened than me in digital graphics.
    b Summary:
    Problem while generating .PDF from Microsoft Word file containing vector graphics. Word file contains embedded .EMF files, which are totally wasted during the conversion.
    b Long version:
    b Step 1:
    I have a Microsoft Word 2007 file (.DOCX), where I need to insert a few UML diagrams from IBM Rational Software Architect. Of course IBM in no way supports any direct export of vector graphics. I figured out that the only way to turn diagrams scalable is to print them to PDF file.
    Link to original PDF file printed from RSA: http://kozel.piasta.pl/print.pdf
    Rasterised version for viewers convenience: http://kozel.piasta.pl/print_ras.jpg
    b Step 2:
    There is no way to insert PDF file directly into DOCX and have good quality. Therefore, I decided to make conversion to EMF which so far was working perfectly (other EMF diagrams are present in DOCX, source is Microsoft Visio). I used Adobe Illustrator CS4 - first I opened a PDF file from Step 1, then I used File -> Export and chose EMF format. I ended up with almost properly looking EMF file, which looks alright in image viewers:
    Link to original EMF generated from Adobe Illustrator: http://kozel.piasta.pl/print.emf
    Rasterised version for viewers convenience: http://kozel.piasta.pl/printemf_ras.jpg
    (yes, the horizontal line is missing)
    b Step 3:
    I inserted EMF file from Step 2 to DOCX. It looked marvelous, so I moved on to generate PDF file. I am using Adobe Acrobat 9 Pro Extended. To generate PDF File I select Acrobat ribbon in Word 2007 and then click Create PDF this way my final PDF contain hyperlinked bookmarks, table of contents, table of figures etc (there features are mandatory and required).
    b Step 4 and final definition of an issue:
    Final PDF file generated from DOCX looks like utter ****.
    Link to final PDF file: http://kozel.piasta.pl/print_final.pdf
    Rasterised version for viewers convenience: http://kozel.piasta.pl/print_final_ras.jpg
    Since I dont know much about computer graphics at all I am pretty much stuck. Something tells me that PDF file generated is Step 1 from RSA is somewhat ****** up, as other applications do not exhibit the same issue.
    If anyone has any idea what might be the solution or can recommend a specific place to post this issue, I would be very grateful.
    The following was tried without success:
    *PDF printer other that Adobe PDF - I have used PDFCreator (GPL license) to print .DOCX. This WORKS and the result is what I expected in the first place. However my headings, bookmarks, references are not hyperlinks in generated PDF file, so I cannot use this method.
    *Conversion from Word 2007 .docx to .doc format (Word 2003)
    *Playing 6h straight with preferences in Acrobat ribbon in Word (this however does not mean it is done, there is simply too many combinations in there)
    *Export PDF from Step 1 to .WMF in Illustrator - total failure, the text in diagrams becomes rasterised
    *Inkscape as a alternative software solution to Adobe Illustrator exported EMF file a failure, its black and white (pretty much the same as in final PDF file) and terribly crooked
    *Virtual printed that prints directly to EMF EMF Virtual Printer direct print from IBM Software Architect contains only raster graphical parts of UML diagrams and no text at all

    In the original PDF those icons are rasters. They may be rasters in the original IBM Rational Software Architect document, too. My guess is they are from a library of icons and are natively raster.
    Those icons survive the trip through PDF > Illustrator > EMF > Word. The problem seems to happen somewhere during or after the import into MS Word, which makes sense (verifies overall suckiness of Word). That also seems to clear Illustrator of any wrongdoing here. It has plenty to spare.
    Generally I leave Word issues alone. If you want to use a a hammer as a screwdriver you can't blame the hammer for ******* up the head of you screw, or the screw for getting it's head ****** up by your hammer. But given the verbosity of your post and thoroughness of your troubleshooting I assume the hammer-as-screwdriver is not your choice.
    My experience is limited when working between Illustrator and Word, but I have learnt a few lessons. (1) People who want files in Word have low standards and don't know vector from raster from rectum. (2) Illustrator's EMF export is ****. Thus, Export to PNG has been a solution that (touch wood) has not made anyone come back with a complaint. If print is the final destination, then use 300 ppi with antialiasing OFF. If the destination is on-screen presentation or (Ewww!) Word-generated HTML, use 72 ppi with antialiasing ON.

  • Embedding FULLY SCALABLE SWF in PDF

    Hello...good people...
    I would like to embed a FULLY SCALABLE Photoshop Zoomable photo (swf) and Adobe Bridge web gallery (swf) inside my pdf. After watching the AcrobatUserCommunity Tech Talk tutorial "Embedding Flash in PDF" - September 2009 (https://adobechats.adobe.acrobat.com/p56758970/?launcher=false&fcsContent=true&pbMode=norm al) and following its instructions (I encourage EVERYONE to watch this entire video...but for this topic 0:29-0:46 is what you need to watch...awesome stuff!!!), I am glad to say I can successfully embed a PS Z-photo and Bridge web gallery. My problem is...the magnification (zoom) on the Z-photo AND gallery has to be 100% and higher. Anything lower, cropping occurs. My question is: how do I modify the Flash files and what applications do I use to make Zoomify and the Bridge web gallery FULLY SCALABLE? In plain English, I'd like to  see the ENTIRE Z-photo and gallery at 50% or even 25% zoom.
    My tools:
    Acrobat 9 PE

    PS CS5
    Flash Builder 4
    Bridge CS5
    Sothink SWF Decompiler
    If anyone can provide step-by-step instructions as to how to do this, I would greatly appreciate it!!!

    I've been having Constant failures in setting up scalable wordpress with no luck on finding a fix. 
    Update ClearDB database failed is the most common issue, with Update deployment being the second issue. I though maybe it had to do with Azure changes over the last few months (beta portal), but have yet to successfully deploy a site. 
    Any suggestions / fixes would be greatly appreciated. 
    Also, i've tried utilizing the support link but it seems to hang perpetually (regardless of browser) when checking my subscription. 

    Hi,
    Two points need confirmed:
    1.Have you already purse the ClearDB database?
    2.What's error did you encounter when you scalable WP site?
    Regards,
    Will

  • LARGE Report | Heap space error | Scalable mode causes XDOIOException

    hi,
    we have a report that returns many records causing a fairly big memory consumption which results in a java heap space error.
    i have read the following post 'Error: Java Heap Space with the scalable mode setting.
    i activated the scalable mode feature for this report, however, after outputting the report again, i get the following exeption:
    oracle.apps.xdo.webservice.exception.OperationFailedException: PublicReportService::generateReport failed: due to oracle.apps.xdo.XDOIOException
    i activated the setting via the xdo.cfg in the according report-folder. the .cfg looks like this:
    <config version="1.0.0" xmlns="http://xmlns.oracle.com/oxp/config/">
    <properties>
    <property name="xslt-scalable">true</property>
    </properties>
    </config>
    can somebody give me a hint in which direction i should look for the error? the exeption tells me nothing to be honest.
    the report works fine with less records - with activated scalable mode however ill get the exception.
    would be very glad for advice.
    thanks a lot.

    - Which Application server are you using: OC4J, Weblogic?
    - Did you increase the app server heap size?
    - Enable the DEBUG mode to troubleshoot this issue: http://bichaos.blogspot.com/2011/04/enabling-log-messages-in-bi-publisher.html
    - Start testing a small rowset and then continue increasing it until you get the error.

  • How to make OBPM 10.3g solutions highly scalable and performant?

    Hi experts,
    I would like to request some advice on how to make Oracle BPM 10.3g based solutions highly scalable. In our organisation, we are rolling out few processes (3-5) on OBPM 10.3g, with couple of 100 concurrent users on each. But going forward, we expect at least 50 processes, with concurrent users on each process reaching upto 500-1000. We understand that each process could be packaged as separate OBPM project, targeted to separate OBPM engine, where each engine itself is targeted to a separate WebLogic server cluster. Is this the correct approach?
    Apart from above, are there any additional factor/apporach that we must consider while implementing our solution?
    Is there any documentation that discusses how to improve the performance/scalability of OBPM 10.3g solutions?
    We would highly appreciate any pointers.. Many thanks.
    Brgds,
    Amit
