How do I select everything inside a JTextArea?

I believe I have to do this:
textarea.selectAll();
But it doesn't show graphically that all the text is selected inside the JTextArea, and I want to show that to the user....
Help????
V

If the text area does not have focus is does not paint the selected text. That's two for two...
I was invoking that code in a button's click event, so that the JTextArea lost focus when a user clicked on the button...
Thanks,
V

  • How do you select everything on all pages? "Select All" does only a single page.

    I can't seem to figure out how to select everything on all 20 pages of my document at one time. The "Select All" function only selects everything on a single page. (which is hardly "all")
    I am making a PDF and creating my text to shapes/outlines. Do I seriously have to "select all" and "convert text" 20 times, once on each of my 20 pages? Its taking forever. Help me streamline, please.

    For whatever reason, there have been several posts about converting text to outlines. It really needs to be emphasized that converting text to outline is extremely poor workflow and should be avoided at all cost. If the sole reason for converting to outlines are font issues, you need to learn how to make PDFs correctly. And if it's a printer request, you should (if possible) solicit quotes elsewhere. Wasn't there a poster a few weeks back who neglected to save a copy of his file before coverting text to outlines? Just for that reason alone you should never outline text. Guarantee that day will come when you forget to dupe the ID file so you can edit again at a later time. I would package a job and send the printer the ID file along with fonts and images before I sent them PDF with fonts converted to outlines. And I haven't done either of the two in years.

  • How can I select areas inside incomplete shapes?

    Hi,
    I'm often required to open PDF drawings outputted from AutoCAD and add colour to them. I do this by opening the PDF in Illustrator and drawing colour shapes in a layer underneath the CAD drawing. Illustrator is good at handling all of the lines from the PDF, but shapes are never interpreted as connected shapes, they are always broken shapes made up of lines. I find it's faster to re-draw them in a layer underneath than to try to join the broken shapes.
    Ideally it would really speed up my workflow dramatically if Illustrator had an area select feature like Photoshop, for example if I could just click inside the broken shape with the magic wand tool and it would select the area.
    Is it possible that this feature exists in Illustrator and I just haven't found it? Any recommendations would be appreciated.
    G.

    Do this:
    1. Use the shape tools to draw a few ordinary closed paths, overlapping each other partially. .25 pt. stroke, no fill.
    2. Select all the paths. Object>Path>Add Anchor points. Repeat 8 times or so.
    3. Select>Object>DirectionHandles.
    4. Edit>Cut.
    5. Delete.
    6. Edit>PasteInFront.
    Now you have a what looks like enclosed areas, but is really just a bunch of tiny open paths. You've simulated the kind of thing you frequently get from CAD exports.
    7. Select all.
    Now record an Action that performs these steps:
    1. Apply 1 pt black stroke with round endcaps and joins.
    2. Object>Path>OutlineStroke.
    3. Apply the Merge Pathfinder.
    4. Object>CompoundPath>Release.
    Stop recording.
    Everything will look like it just acquired a black fill. But now you have a Group of ordinary closed paths with black fills and no strokes. The outermost closed path completely surrounds the others and is offset from them by 1 pt. (thus, serving as the line work). You can now click the fills of the other paths and apply whatever fill colors you want.
    The Action can now be applied with one click.
    I frequently use a slight elaboration of such an Action when importing DXFs of exploded assembly drawings. I Lasso or marquee-select around the disjointed paths that make up the drawing of an object, and then run the Action with one click. The result is white-filled closed paths, simplified to remove excess anchorPoints, with a heavier weight outline around the outer perimeter. (Helps clarify individual parts in an exploded drawing--not proper thick/thin treatment, but servicable. Also serves for color-coding by the thick outlines if you.)
    The exact best steps to include in the Action depends partially on the nature of the kinds of drawings you typically import; but the principle is generally like that outlined above.
    All of this (including workarounds with LivePaint) is, of course, ridiculous workaround for Illustrator's ridiculous lacking any kind of intelligent join command.

  • How do i select everything under my pen tool path.

    I have made a path with my pen tool around an image that i desperately want. But if i delete the pentool path everything underneith stays alive. They are both in the same layer so i do not know how to do it. Any help?
    Yours sincerely,
    Joep

    Joep,
    My guess is that you will obtain the desired appearance if you select both the Pen Tool path and the image and Object>Clipping Mask>Make (Ctrl/Cmd+7).
    That will show what is beneath the path and hide what is outside it.

  • How can write select statement inside case operator

    Hi all,
    I like to write a query which get result from other table in case operator.
    e.g
    select a,b,c from dual
    where a=1
    and b=case when b is null then "select any value from other table" else null end;
    Please help me to write this query.
    Thanks

    sorry, but thats funny.
    You ask for case with subquery and choosed a solution with decode as correct.
    Furthermore, the solution proposed might not be so useful.
    First of all many people prefer case over decode, because of understandability and readability of the code (toad has this as a coding rule built in too)
    Secondly in this case the decode does nothing. Take a closer look:
    select a,b,c from tableA a
    where a.a = 1
    and a.b =(select decode(a.b,null,( select 1 from tableB b where rownum = 1 ),a.b) from dual)the decode chooses the subselect if a.b is null. But if a.b is null the a.b on the left side is null also, so the predicate will never be true.
    aside from this, you can write this shorter as
    a.b=nvl(a.b,(select 1 from tableB b where rownum = 1))so what will work in such a case might be
    ANEXPRESSION(Literal, scalar subquery, ...) =nvl(a.b,(select 1 from tableB b where rownum = 1))otherwise look for a solution with case ;-)
    regards

  • How to select everything right from playhead (like in fcp7)

    You know, this handy old useful tool that allowed you to either select trackwise or for all tracks everything that was right or left the cursor, to -you name it- select everything, move it to the right, and then insert something in the gap?
    Everytime I edit something with FCP X at a certain point, I find myself zooming out and manually drawing a selection around everything right from my playhead, to move it there, using the position tool.
    Luckily I've only been editing stuff that was like 5 minutes long maximum. But I wonder how to do this in a longer project? This simply can't be the way...to zoom out and manualy draw a selection every time? I know it probably has something to do with the magnetic timeline but...seriously?

    How do you select multiple messages/conversations on SMS/MMS to forward or save to memory card on Samsung Stratosphere? 
    My screen is cracked and I need to replace my phone and I don't see a way of selecting multiple messages or even conversations one at a time to forward them to email or to save them to a memory card.  I can delete thread but can't forward it or move it.  Is there a setting somewhere that will move the storage location for messages to the memory card instead of internal?
    If not, any suggestions on backup apps?  I have heard of Txtract to back up SMS and MMS messages, and Titanium Backup to back up everything (SMS, MMS, apps, app data...).  Anyone have any experience with those, or other suggestions?
    Thanks!

    To delete your my photo stream photos, open the album, tap Edit, tap the photos, tap the trash icon. If you want to keep a copy of them on your device, save them to your camera roll first.

  • Drive Utility Help Viewer "does not know how to handle selected URL"

    I have Drive Utility 10.5.6, according to . I'm trying to reformat a FAT32 partition on an external drive to Mac OS X Ext. Journaled in preparation for using SuperDuper to back up my Mac HD boot partition. For a time, which seems to have passed, now that erasing the partition has been done. The Disk Utility Help wouldn't work. Instead of putting up topic information, I got a message saying "Help Viewer does not know how to handle selected URL", followed by an reference to an html file that allegedly existed inside a set of folders inside the app. Where, of course, Finder cannot see. Once the erasing was done, Help seems to have come back. I tried Apple Support, but could only get a reference to OS 9 Appleworks macros not working in OS X. No help at all. Is this a question? I don't know. Help is working now. But for a while it was very annoying. It must be one of those little windows glitches that no one ever bothered to fix.

    In order to change a FAT or NTFS formatted drive for use with OS X you will need to do the following:
    Extended Hard Drive Preparation
    1. Open Disk Utility in your Utilities folder.
    2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
    3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID (for Intel Macs) or APM (for PPC Macs) then click on the OK button. Click on the Partition button and wait until the process has completed.
    4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
    5. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.
    6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.
    If you have an Intel Mac and can partition the drive using GUID then you can have FAT32 and OS X partitions on the same drive.
    As for problems with the Help viewer see:
    In most cases doing the following will restore the Help Viewer:
    1. Trash the following three files, if extant:
    /Home/Library/Preferences/com.apple.help.plist
    /Home/Library/Preferences/com.apple.helpui.plist
    /Home/Library/Preferences/com.apple.helpviewer.plist
    2. Trash the /Home/Library/Caches/com.apple.helpui folder.
    3. Empty the Trash and Restart.
