Basics of caret appearance/disappearance

I have a jdk 1.4.2 applet consisting of several complex visual components on the form. Each visual component contains some combination of JTextField, JButton and/or JTable. I'm trying to troubleshoot a program bug where each JTextField, either standalone or as part of a visual component, is capable of displaying a blinking caret independently, meaning several blinking carets could appear on the form simultaneously, even though only field has the keyboard focus. These carets are appearing because of the applet's logic in response to a user action. This wasn't by choice or design, but that's how it came to be. I also have a case where the entire form has no blinking caret at all. My goal is to have only one blinking caret present on the form.
I've gone through the code but so far haven't come across anything obvious. I should mention that the code is replete with all kinds of listeners (focus, action, key etc), their handlers, and some standard methods like isFocusable overriden. I'm trying to approach the issue from a different angle. The most basic answer I'm seeking is: what set of conditions must be present in order for (a) a caret to disappear at a textfield and for it appear at a different textfield (b) a caret to remain at a textfield while another caret appears at a different textfield, and (c) a caret to disappear from a textfield and not appear anywhere else?

what set of conditions must be present in order for....Every text component has a Caret associated with it. The default behaviour is that the Caret is made non-visible when the text component loses focus. Then when the text component gains focus the Caret is made visible again.
So there are no normal conditions that would cause the behaviour you describe. So you must have some custom code that is causing the problem. Maybe you are attempting to share the same Caret for multiple text components. Or maybe you are using a custom Caret that is not implemented correctly.

How to make a block appear / disappear at runtime ?

Hello,
I'd like to make a whole block appear and disappear at runtime.
The block has no "visible" property, nor has the frame surrounding it on the canvas.
Of course I can set this property for each item in the block, but I would like to find something easier.
Thanks for your help.

stack canvas is a better way.
But the situation matters. after the block 'disappears', you leave the blank space there or resize the canvas ? if you have resize it to smaller, then you may set the window size in one built call.
Thus the detailed way depends one the detailed requirement.

Randomly appearing/disappearing images

I have two images on a page that will randomly appear and
disappear when the page is refreshed. Sometimes both appear at the
same time, but with subsequent refreshing of the page one of them
will disappear, then it might reappear while the other one
disappears, then both will come back, etc. As far as I can tell it
truly is random.
I've gone over the code very methodically looking for any
anomalies, and there's nothing obvious to me. It occurs in both IE
and FF. This is the first web page I've built using Dreamweaver's
layout mode to create tables, so that may or may not be a factor.
But it's time to ask for help, because I really am stumped at this
point.
I would be more grateful than I can express for any tips
anyone can offer. You can view the code here:
http://stressfreewebsites.com/temp2/ex-a/temp2-a.html
The two rogue images are the header bars in the main text.
I have to laugh myself at the irony of the website's theme:
building 'stress-free' websites for small businesses. Stress-free
for the end user perhaps, but only because all the stress is on my
end, lol.

> This is the first
> web page I've built using Dreamweaver's layout mode to

We are all hoping it's the last, too.
In my opinion, there are three serious problems with Layout
Mode -
1. Perhaps most importantly, it sits between you and *real*
HTML tables,
and fools you into believing that concepts like "layout cell"
and
"autostretch" really mean something. They do not. As long as
you use
Layout Mode, you'll never learn one of the most important
things for new web
developers - how to build solid and reliable tables.
2. Actually, #1 wouldn't be *so* bad, except that the code
that is written
by Layout Mode is really poor code. For example, a layout
table contains
MANY empty rows of cells. This can contribute to a table's
instability.
In addition, if your initial positioning of the table's cells
is a bit
complex,
Layout Mode will throw in col- and rowspans aplenty as it
merges and splits
cells willy-nillly to achieve the pixel-perfect layout you
have specified.
Again,
this is an extremely poor method for building stable tables,
because it
allows
changes in one tiny cell's shape (i.e, dimensions) to ripple
through the
rest
of the table, usually with unexpected and sometimes
disastrous consequences.
This is one of the primary reasons for the final result's
fragility - read
this -
http://apptools.com/rants/spans.php
3. The UI for Layout Mode is beyond confusing - many options
that you might
want to use are inaccessible, e.g., inserting another table,
or layer onto
the page.
I can understand the new user's desire to use this tool to
make their life
easier,
but the cost is just too heavy in my opinion.
To make good tables, keep it simple. Put a table on the page,
and begin to
load your content. If you would want a different table
layout, instead of
merging or splitting cells, consider stacking tables or
nesting simple
tables instead, respectively.
And above all, do not try to build the whole page with a
single table!
Luckily, Adobe understands the problems created for the
unsuspecting user
who falls into this trap, and has elected to remove this
feature altogether
from the next version of DW. The time is right for you to
begin working
with tables properly!
To read more about this approach, visit the DW FAQ link in my
sig, and run
through the table tutorials.
I was not able to duplicate your image behavior after many
refreshes in both
IE7 and FF2x.

Can more than one build in or out object appear/ disappear simultaneously?

I have objects (images and text boxes) appearing one at a time but I would like them all to disappear simultaneously so is there some way you can group objects to appear and disappear at the same time?
Thanks

Just a couple of questions first, when you mentioned "Set all the Build Outs to occur together." How do I actually do that? I tried highlighting them all and right clicking to see if it gives me an option to do that and look everywhere but couldn't find that function.
Again, if I'm understanding you, this is a very straightforward effect to produce. In the Build Inspector, set up all the Build Ins for the objects, then specify the Build Outs. Now click on the More Options button, which will reveal the Build Order drawer. For each of the Build Outs except the first, select the build in the order listing, then in the Start Build drop down menu, choose "Automatically with build #", where "#" is the number of the first Build Out.

Struggling with Appear/Disappear Effects

I've been transitioning to Keynote from PowerPoint for a while now, but so far have only tested the Keynote waters with simple presentations. Now I'm moving up to something fairly complex, something I could do easily in PowerPoint and can't quite get in Keynote.
The short of it is I have a list of names. I want the names to fade in and out, but not just one at a time. One will come in, there's a pause, and then the next appears. Then as the third comes in the first disappears. As the fourth appears, the second disappears. And so on.
Without going into more detail or using this list as a classroom, is anyone willing off-line to walk me through this? You'd be doing a great service in freeing me from another Microsoft application!

Hi,
1. Place all of the names (as text or graphics) on the slide.
2. Click on the Build Inspector icon in the main Inspector window.
3. Select the objects you want to animate on the slide and, under the Build In "tab" on the Build Inspector, choose an animation style from the drop down menu (for example, choose dissolve). You don't necessarily have to do them all at once but it's faster to just assign everything you want to animate with a "Build In" so you can start timing every item and getting them 'in' the build sequence.
4. Click on the "More Options" button at the bottom of the Build Inspector window - the drawer will slide out to one side or the other. Here you can see everything that you've assigned a build for that slide. It also shows the order of things that are being animated from first to last beginning at the top of the list.
5. Click on the object you want to animate first and you'll notice it will be highlighted in the Build Inspector's drawer. You can now see the relationship between the objects on the slide and their animation order in the drawer. Simply reorder the items in the drawer's build list to what you need (name 1 is at the top followed by name 2 then 3 and so on).
6. Now that you've got your "In" builds arranged, it's time to get the first one to fade away when you want it to. Click on the first name you'd want to disappear in the Build Inspector's drawer list.
7. Click on the "Build Out" tab in the Build Inspector. Pick an animation style (ie dissolve) and it will add the Build Out to the bottom of the drawer list. Notice that both the IN and OUT builds for that object are highlighted.
8. Because my writeup here only has 3 text objects, the OUT build will be at the bottom and I don't have to move it but if you have more than what I'm demoing, that's how you'd move it around. Click in the empty space in the Build Inspector's list area to deselect everything and then click once on the OUT build for that object. Now you can move it wherever you want it in the sequence.
As for having things pause between individual builds, you can either give each object's build in stage to begin "On Click" or "Automatically after/with prior build" using the drop down menu at the bottom of the Build Inspector's drawer. If you want to do the "automatically after/with" option, you can set thet Delay time there as well. I've found that this time varies slightly depending on how fast your machine is and what else is running on the slide.
Hope this helps you get started,
Matt

PopupManager causes caret to disappear

Hi, I hope someone can help me. I have a popup that I want to serve as a warning of sorts, without stealing the focus.
If I pop it up on focusIn for a Halo TextInput, it works as I want it to.
However, if I use a Spark TextInput, the caret seems to disappear. The TextInput seems to still have the focus, because it is still possible to type inside of it. The caret is just no longer visible for some reason.
Please let me know if I'm forgetting to do something important. Or if this is simply a bug with Spark TextInput, I'd be curious if anyone has found a workaround.
Thanks!

File a bug with a test case.

There's this mysterious appearing/disappearing icon in my Dock...

...that every so often spontaneously opens up, then closes right away. I can never get a good look at it, but it appears to be a white "page" (like the TextEdit dock icon) with what looks like a green part in the upper left corner and a black part in the lower right area.
What application might that icon belong to? And should I worry about it?

To clarify, it doesn't happen after each loading of a webpage -- I'm not even sure if it is triggered by opening a web page at all. Sometimes I'll just be watching the screen and it will happen.
Again, the trouble is that the icon just appears and disappears in the Dock before I can get a good look.
I'll try to take a full-screen snapshot (Command-Shift-3) the next time it appears, and hopefully I'll catch it in time...

Illustrator pictures appear/disappear in InDesign CC?

I'm importing two Illustrator CC pictures into an InDesign CC file (Running Adobe CC on Mac OS X 10.8.5).
If I set my display preferences to "Normal", they show up correctly (although an imported Photoshop JPEG appears in low-res). If I put the display into "High-Quality" mode, the photo is fine, but the two Illustrator files disappear, leaving only the bounding/content boxes. If I zoom out to 25%, the Illustrator files are visible on-screen, but at any higher zoom, I get nothing.
What am I doing wrong?

I just recently experieced this issue and when importing an .AI (CC 2014) into InDesign CC 2014. When viewed in Typical Display the proxy would appear and disappear when changed to High Quality Display (HQP). However when Overprint Preview is turned on the .AI file will appear while in (HQP). On a side note, while placing art with import options, the preview did not update when toggling on and off various layer's visibilty.
Trying to troubleshoot, I turned off all overprint settings for element in Illustrator and no difference. The solution that worked for me, I used a blend between three paths. Two of the three used the uniform stroke profile but the last path used "width profile 2". Once I changed the last path to uniform as the others, during placement, the preview worked properly and the vector art rendered correctly in all displays with and without overprint preview enabled.
I hope this helps, anyone else with their files and contributes to a more distinctive cause and quick resolution.
