Problem-less Floating Boxes?
I saw the recent thread about problems with relative positioning. All of a sudden I'm insecure again. I have a page with 34 floating boxes (none nested, but many overlap) and their positions remain stable when my browser window is resized. No sleight of hand, just dragged boxes into position and filled with content (default settings in F.B. inspector). So I was feeling confident. Safari, Explorer, Aol all show the page as locked down, reacting to window re-sizing and scrolling just like any other conventional page design. Should I be worried? Is such a layout going to corrupt itself, or glitch-out, or crawl out from under my bed at night and bite my hand? I'm worried that I'm naive and missing something because of the complexity of that previous thread.
>I saw the recent thread about problems with relative positioning
There are no problems with relative positioning other than not understanding
how it works. There are many *more* problems with absolute positioning,
especially when text is placed in absolutely positioned elements.
> just like any other conventional page design. Should I be worried?
Yes. Resize your text in the browser and see what happens. Or better, post
a link to your page so we can see its code and anticipate problems for you.

I have just migrated a site that I built in CS4 to Dreamweaver CS6. It has this (stupid) floating box that the client wants to be visable as the site is scrolled. It works fine when the browser window is full size, but the box just keeps scrolling till it's out of site when the browser window is made smaller. I was given the code to put this box into the site, so I have no idea why it no longer works in this situation when it worked before I did the monthly update in Dreamweaver CS6.
The site is not responsive, mostly because of this floatingbox and uses two navigation systems. The URL is www.fulcrumcwi.com and I am using version 12.0 in Dreamweaver CS6.
Any help with this would most certainly be appreciated.
Thanks in advance,
NinaHave you ever used this with a responsive site?
I've used position:fixed headers & footers in responsive sites.

I think the sticky text box would be too awkward in % width layouts. But you could try it and see. If it gets in the way on mobile devices, kill it in a CSS Media Query with display:none.

GL floating boxes with rollovers
I'm working on a project that is similar to a target--bullseye in center with rings around it. I have created the text/phrases that go in each ring in Illustrator and put the whole thing together in a layered PS file. No problems yet, but when I separate all of the text/phrase into images with 2 states for the rollover and put them into GL floating boxes, the boxes overlap in some area so the mouseover rollover doesn't always work. For example, mouseover one text image and another one will show the color change rollover because the mouse is really over an area of the image that is transparent. Is the only way around this to re-arrange the box z-index to try to avoid the overlap or is there some way that I am missing? Frustrating!
Like I said, you can use the Set Image URL action for the rollover. You can set multiple actions to change more than 1 pic on mouse enter if you need to. You won't need any more layers than you currently have, and only the area where you place the image map will be active (rollover won't trigger in transparent areas).
As for overlib, (I'm not familiar with that) if it's a javascript that's added to your links/rollovers, you can move it to the image maps in the source, it should work fine. -
My TV is mounted on a wall so I can't connect the Apple TV device. Is it possible to connect to an HD Cable Box and send signal to TV that way? Other problem is that Box only has one HDMI socket so would also have to use a splitter. Tried Apple Support but couldn't offer a solution. I can't be the only person with this issue surely?
Help!No, unless you are using a home theatre system already, your only option is to connect to the TV.

Link Properties For A Single Floating Box
The tutorial that Nate Baldwin referred me to did not cut through my ignorance level on this subject, so I'll try this question phrased another way - more specifically.
If I want to change the link text color within only one single floating box, what do I do? I'm in GoLive 6.http://www.golivebasics.com/csstut/css07.html
If you know nothing about css start with page 1 from the menu on the left. -
I'm having problem with text boxes. Whenever i hit the enter button to start a new line or paragraph, the cursor doesn't drop down to the next line. Instead i get this little red + sign in the box.
You are absolutely right. Thought Enter meant Enter. I was wrong. Thank you for the help.

I am using Adobe GL ver. 6.0 and I just spent hours formatting an image map to show/hide 7 images in floating boxes. I even placed the images carefully so there was no interference with the mouse over on the map. When I preview the page in IE it works fine but with a warning about Active X controls. But when I upload the page to the hosted website it does not even show the hotspots on the image or any type of action. Did I just waste my time? Do I have to go out and buy Flash? Website is at the homepage for www.junglemistorchids.com and the image map is at the bottom of the page. Each orchid should display a larger image with a title. Please help!
To use and understand the .site file is very importent for using golive ... it is the heart and soule
when you begin a new website you have to start by making site/folder/projekt frome in GoLive
Start by taking a backup/copy of you websitefolder now .....
to start a website:
when you open GL you will be askd if you want to "new document" or "new folder" Chose "new document"
(If you already hase GL open, go to file>new document in the menu)
youll get this window:
Chose the site at the left menu and create site in the middel to start/create a new site.
Follow the instuctions in the wizzard (you dont have to specifi anny FPT yet but you can - leav blank if you want to do that later)
Golive now creat a folder on you computer (wher you chose to place it) and GL open you new site...
This is you site window ... ALWAYS work inside this / form this:
Its split in left and right... to the left is filewindow with your files for you webpages and to the right you see the server window wher if conected you can se the files on the server. The new site contains a index.html file and a css folder with a basic.css file (index.html and basic.css are blank) and GL is now ready to work in...
If you find the folder GL made for the site youll see it contains 3 folders and 3 files:
The importent ones are:
web-content folder contains all you pages, images, script and so for you site and are shown in the sitewindows leftside
And the New Site.site file (or what you chosen to name your site in the wizzard)
The .site file is the is the one that contains the site window in golive... it keeps track of all link/content/actions and so on you site... and when you want to work on the site you simple click this one.
When you work in the site window GL will know what you do and where the difrent things are, and if you move eg. a picture/file frome one place inside the window to another GL will know this and rewrite the corosponding URL's (les work for you)
When you ad adctions (funktions) to a page golive use its scriptLibery to make the scripts neede ... and place a "script" folder in the site:
That folder/file contains the scripts neede for the actions to work.. If you dont work in the sitewindow/file GL dont know where to place this and therfor the URL will point to GL's own folder and the script will only work local...
(You can in the prefrence chosae to write scripts in the document, but i wont recomend that)
When you ar done and want to upload you site to a server... right click in window and chose puplish server .. if you have not specifide a server youll be askd to.. else it will connect ...
Now you can right click in window and chose puplish server and chose how to upload you site and Gl will upload all the files with correct url's including the script folder (Before upload its a good ideer to rightclick and chose update>flatten scriptlibery to make the scriptLib smaller)
Hope this helps you understand the site file and importens of using this..
Now for getting you website to work corectly.... -
A floating box has suddenly appeared on the lower left of my screen with white text on a black background telling me about whatever my cursor is hovering over at any given moment. It's driving me nuts. I'm sure it must be part of Help or Info, and it probably just takes a simple keystroke to get rid of it, but I can't seem to find that blasted keystroke!! Please help. [OS X 10.8.4; Mac Pro]
welcome

Floating boxes applet with drag events need click event
I Have an applet cobbled from the net & modified. Is works but needs one major event added. It draws "Graphics.drawline" boxes with a text "String" inside each box ( the text string represents an URL location). These "boxes" are objects which are "draggable to other locations on canvas & therefore can be independently positioned by user. Each box redraws itself periodically to a slightly different screen location & becomes stationary after a 5 or 6 seconds. The point is, all of this "drag & mobility" behavior must remain intact & is not part of the "problem task".
Task: Need to have an "event" behavior added in one of two ways ( or a 3rd way if there is another ) whichever is quickest/ easiest. "Clickable mouse events" must be added to each box. ( boxes are built in a loop so adding to one will add to other locations & create as many "buttons" as there are boxes) . At each box's location, clicking one box should be an event which fires & clicking a different box should be a separate event which fires. Separate , so that URL location can be "hotlinked" to each box. That URL is currently displayed in the boxes (visible when running applet).
1st possible solution: Exchange these "boxes" which appear on canvas into clickable event "Graph panel.buttons" ( for example or some other clickable object) which maintains existing "drag" behavior of boxes. These buttons must each have "clickability" with mouse events to enable placing "getAppletContext. showDocument()" code with these events ( e.g., "hotlinked" to http locations).
or
2nd possible solution:. The drawstring boxes are currently dead string text with no event model other than the "drag" feature associated with each box. Must add an additional mouse event behavior to existing boxes so they are "clickable" ( or text inside is clickable) and can then execute "showDocument()" URL when clicked independently.
Maybe there is a #3. I don't know what that would be. Open to try anything without losing the drag & placement mobility of existing boxes.
These "boxes" could be images, or event buttons - doesnt matter.
Not sure if #2 is possible & have not been able to accomplish #1. Must stay within existing AWT framework so IE browsers can run it natively ( which of course IE cannot run Swing graphics unless a Sun plugin loaded ).
Applet is a single file ( creating 4 classes).
html file (which invokes it) passes a string param which is broken into above noted URL strings in each box.
Running this applet, you see a "button" event ( at base of canvas labeled "NewUrl" ) which pops up an url location when clicked ( using "showdocument"). This button is not attached to locations or text of each box object ( which is the "task" to accomplish) . The button does represent the kind of event behavior which each "box" should have when task is achieved. So the box can be exchanged with buttons or the boxes can be imbued with events to hyperlink like a button.
In spirit of solution #1, here is the bonehead attempt I tried which did not work: copied entire "if" block of logic from the button event (sited in preceding paragraph) into region of code which builds boxes ( "for" loop of "drawstring" method).
"g.drawString(doit, x - (w-10)/2, (y - (h-4)/2) + fm.getAscent());"
I copied all the "if" block of logic for button creation into the area immediately after the above line ( for loop which builds the boxes). Hoping that I could create buttons with events, along with all the boxes (which are getting created using "drawstring" above in a "for" loop). These "buttons" must also have positioning info of each box to appear in different locations on the canvas. Positioning data is not in that "if" block of code but it would have been a start to get the multiple buttons created ( even if all drawn in one spot). The "if" code block I've provieded for an example begins with the line:
" if ("NewUrl".equals(arg)) { "
and ends with with lines:
" return true; "
" } " //< -- end of above if block
This full "if" block can be seen in the listing below:
This "if" block creates the "NewUrl" button. Of course, I got a bunch of errors when I tried to copy this block to the above location:
variable: "arg" "not found in class GraphPanel".
methods: "getcodebase, showstatus, getappletcontext()"
"not found in class GraphPanel".

instructions to compile :
0 : The discussion becomes easy to follow after 1st compiling
& viewing the applet.
1. : cut out applet code.
2. : the post somehow deleted all references to "" <--- HERE
see, the data has been deleted again as I preview this post.
( that "" should contain an "i" array increment argument:
"open square bracket" "i" "close square bracket" ) array
so "javac Box.java" will get 10 errors. These "[" "i" "]"
array args must be replaced to compile the code.
3. : All array variables inside the 10 "for" loops ( the bare words
"edges" and "nodes" ) without array increment "i" should
read "edges" "[" "i" "]" & "nodes" "[" "i" "]".
The 10 location lines are approx:
line #65, #129, #136, #149, #195, #283, #311, #331, #477, #522
4. : These 10 edits reqresent a missing "i" to all 10 for loop arrays.
for eddges & nodes. fix this & javac Box.java" will get
4 class files.
5. : cut "Box.htm" from post & do "appletviewer Box.htm"
or put in an apache "htdoc" or tomcat "servlet" http delivered
directory & call "http://localhost/Box.htm.
6. : of course, selecting the event button "NewUrl" will not
work in appletviewer but will work in an http web location.
7. : post your questions to problem or fixes to problem as I'm
monitoring closely. TIA.Thanks for code post tip to fix array deletion problem.

Floating "boxes" applet with drag events need ckick events
I Have an applet cobbled from the net & modified. Is works but needs one major event added. It draws "Graphics.drawline" boxes with a text "String" inside each box ( the text string represents an URL location). These "boxes" are objects which are "draggable to other locations on canvas & therefore can be independently positioned by user. Each box redraws itself periodically to a slightly different screen location & becomes stationary after a 5 or 6 seconds. The point is, all of this "drag & mobility" behavior must remain intact & is not part of the "problem task".
Task: Need to have an "event" behavior added in one of two ways ( or a 3rd way if there is another ) whichever is quickest/ easiest. "Clickable mouse events" must be added to each box. ( boxes are built in a loop so adding to one will add to other locations & create as many "buttons" as there are boxes) . At each box's location, clicking one box should be an event which fires & clicking a different box should be a separate event which fires. Separate , so that URL location can be "hotlinked" to each box. That URL is currently displayed in the boxes (visible when running applet).
1st possible solution: Exchange these "boxes" which appear on canvas into clickable event "Graph panel.buttons" ( for example or some other clickable object) which maintains existing "drag" behavior of boxes. These buttons must each have "clickability" with mouse events to enable placing "getAppletContext. showDocument()" code with these events ( e.g., "hotlinked" to http locations).
or
2nd possible solution:. The drawstring boxes are currently dead string text with no event model other than the "drag" feature associated with each box. Must add an additional mouse event behavior to existing boxes so they are "clickable" ( or text inside is clickable) and can then execute "showDocument()" URL when clicked independently.
Maybe there is a #3. I don't know what that would be. Open to try anything without losing the drag & placement mobility of existing boxes.
These "boxes" could be images, or event buttons - doesnt matter.
Not sure if #2 is possible & have not been able to accomplish #1. Must stay within existing AWT framework so IE browsers can run it natively ( which of course IE cannot run Swing graphics unless a Sun plugin loaded ).
Applet is a single file ( creating 4 classes).
html file (which invokes it) passes a string param which is broken into above noted URL strings in each box.
Running this applet, you see a "button" event ( at base of canvas labeled "NewUrl" ) which pops up an url location when clicked ( using "showdocument"). This button is not attached to locations or text of each box object ( which is the "task" to accomplish) . The button does represent the kind of event behavior which each "box" should have when task is achieved. So the box can be exchanged with buttons or the boxes can be imbued with events to hyperlink like a button.
In spirit of solution #1, here is the bonehead attempt I tried which did not work: copied entire "if" block of logic from the button event (sited in preceding paragraph) into region of code which builds boxes ( "for" loop of "drawstring" method).
"g.drawString(doit, x - (w-10)/2, (y - (h-4)/2) + fm.getAscent());"
I copied all the "if" block of logic for button creation into the area immediately after the above line ( for loop which builds the boxes). Hoping that I could create buttons with events, along with all the boxes (which are getting created using "drawstring" above in a "for" loop). These "buttons" must also have positioning info of each box to appear in different locations on the canvas. Positioning data is not in that "if" block of code but it would have been a start to get the multiple buttons created ( even if all drawn in one spot). The "if" code block I've provieded for an example begins with the line:
" if ("NewUrl".equals(arg)) { "
and ends with with lines:
" return true; "
" } " //< -- end of above if block
This full "if" block can be seen in the listing below:
This "if" block creates the "NewUrl" button. Of course, I got a bunch of errors when I tried to copy this block to the above location:
variable: "arg" "not found in class GraphPanel".
methods: "getcodebase, showstatus, getappletcontext()"
"not found in class GraphPanel".

instructions to compile :
0 : The discussion becomes easy to follow after 1st compiling
& viewing the applet.
1. : cut out applet code.
2. : the post somehow deleted all references to "" <--- HERE
see, the data has been deleted again as I preview this post.
( that "" should contain an "i" array increment argument:
"open square bracket" "i" "close square bracket" ) array
so "javac Box.java" will get 10 errors. These "[" "i" "]"
array args must be replaced to compile the code.
3. : All array variables inside the 10 "for" loops ( the bare words
"edges" and "nodes" ) without array increment "i" should
read "edges" "[" "i" "]" & "nodes" "[" "i" "]".
The 10 location lines are approx:
line #65, #129, #136, #149, #195, #283, #311, #331, #477, #522
4. : These 10 edits reqresent a missing "i" to all 10 for loop arrays.
for eddges & nodes. fix this & javac Box.java" will get
4 class files.
5. : cut "Box.htm" from post & do "appletviewer Box.htm"
or put in an apache "htdoc" or tomcat "servlet" http delivered
directory & call "http://localhost/Box.htm.
6. : of course, selecting the event button "NewUrl" will not
work in appletviewer but will work in an http web location.
7. : post your questions to problem or fixes to problem as I'm
monitoring closely. TIA.Thanks for code post tip to fix array index deletion problem.
Here is code reposted using "code" delimiters which will
compile straight out of cut/paste.

I have a problem that just affects iCal. An error box popped up when I was trying to past something into a new appointment. The box blocks me from using the calendar. I can't clear the error box. It has nowhere to click to close it. Nothing happpens when I right click it. I have force closed iCal, but when it reopens the error box is still there blocking any use of the calendar. There is no error number, just a copy of the text I was trying to paste.
Try this.
Reset the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons. -
I'm having problems (1) selecting onscreen text, (2) resizing menu boxes and selecting menues with the cursor. I'm not able to select menus and move them. I'm not sure how to correct this.
1) This is because of software version 1.1. See this
thread for some options as to how to go back to 1.0,
which will correct the problem...

2) This tends to happen after videos. Give the iPod a
minute or two to readjust. It should now be more
accurate.
3) This?
iPod shows a folder icon with exclamation
point
4) Restore the iPod
5) Try these...
iPod Only Shows An Apple Logo and Will Not Start

iPod Only Shows An Apple Logo
I think 3,4, and 5 are related. Try the options I
posted for each one.

I just noticed that one of the restore methods you posted was to put it into Disk Mode First rather than just use the resstore straight off, I Have tried that and seems to have solved the problem, If it has thank you. previously I have only tried just restoring it skipping this extra step. Hope my iPod stays healthy, if it doesnt its a warrenty job me thinks any way thanks again -
Problems with text box borders, tabbing and saving doc in Acrobat Pro 7.1.0
When I view my form document in Acrobat Reader, there is a red border around several text boxes
in which I've selected 'NO border'
Also, I've selected 'column order' for tabbing, but tabs continue to function in order in which I inserted form item (text box, check box or radial button). Since I didn't insert these consecutively, tabs no jump all around the form instead of proceeding in order from top to bottm and left to right.
I've checked for Mac Acrobat Pro updates and see that there are three - 7.1.1, 7.1.3, and 7.1.4, and am downloading them for install.
Do any of the updates fix these problems? Or how can it be fixed?
On opening document in Reader, I also get a message informing that document cannot be saved with changes and must be printed, even though I've created it with fillable forms.
Is there some setting for allowing document to be saved?
I want to be able to have recipient be able to download form, fill it out, save changes, attach to email and return it to me.This has been a problem since version 8 on the mac. Acrobat 7 on the mac worked fine with the right side trim but not on the PC.
We are still having this problem with Acrobat 9.4.0 on the Mac & PC.
This has now been an issue for 2 versions of Acrobat Pro.(8 & 9)
Being in Pre Press and having to constantly set the trim for jobs, this is now taking up too much time and costing money.
Please fix this Adobe.
and on another note. how hard would it be to display the trim (if set) next to where the page size is?
If the trim is set it should display it! why should we have to go to document/crop pages>trim.
Im in a busy Pre Press Dept and the amount of times you have to check a trim size is stupid.
I always set prefs to display crop / trim / and bleed boxes and this helps but it should display it if its set.
Thanks
Hope this is resolved soon.
