Combo box colour question

If i want my JComboBox items to appear against a white background instead of the default grey background, do i have to use a custom renderer or can i use one of the inherited paint () methods?
If i can use paint method, what do i paint?

Try
UIManager.put( "ComboBox.background", color );
UIManager.put( "ComboBox.foreground", color );

Combo-box format static

I tryed posting this question before with no success, so I
thought I would
re-explain.
i am using a combo box component (using flash mx 2004 pro)
and have been
able to customize the fonts, colour, etc. of the list once
the user clicks
on the combo box, but can not figure out how to make the
initial combox
box text use the embedded font. Any suggestions?
You can see the combo box in question at :

thank you
Tim

Thanks, that worked great! one more quick question, is there
a way to
actionscript the component so that the comboc box doesn't
have rounded
corners when it's not selected?

Change combo box selection dynamically?

I would like to have a combo box change its selection dynamically according to what is selected in another selector. As far as I can tell from reading the Help, this feature is available for List Boxes, List Views and List Builders only ("The Dynamic Selected Item functionality is available in list-based selectors") and based on the wording I assume that it is currently unavailable for other components. Is this true? If so I would like to formally request that other selectors - particularly combo boxes - be included.
The use case for me is this: After the user has already inputted information and digested some of the output, they eventually reach a section of the project that appears only under certain conditions. This area is about 800 pixels to the right of the original combo box in the inputs area, and so in order to quickly change that selection they would have to go look for the original selector, which could easily discourage them from browsing that particular selection. Hopefully this makes sense.
It would also be great to hear back that this kind of feature request can actually be made in this way. I've submitted a few similar requests in the past and did not see an acknowledgment, and so I am still unclear as to whether or not feature requests are even possible.
(Edit: I thought about creating duplicate overlapping instances of the combo boxes in question and, using dynamic visibility, control which appears according to the current selection. But this is only suitable for smaller lists).

Thanks, Alan. I am currently working on a similar solution. Seems to be the best for my situation, but it is far from elegant.

The Filter component requires that the underlying Excel data be structured in a pretty specific way. As far as I can tell, I would probably have to rip apart my XLS and redesign it in order to make use of that component. Perhaps in a future generation I'll give it a go, but I've already gone through too many redesigns this time around.

Combo boxes appear in reverse and info cannot be read when selected

Half of my combo boxes appear normal and half appear with the drop down arrow on the right side of the box. the choices, when selected, appear above the arrow and are barely legible. some of the boxes appear perfectly normal and some are like this with no apparent reason as to why. I have not changed combo box settings through the duration of my project to make this happen, so it appears random. . . I have already done hundreds of pages and need to go back and check all of these again but need to do it right this time!
any help would be great,
thanks all

My mistake, the combo boxes in question are appearing inverted where the arrow appears on the left side facing upwards. and the answers, when chosen, appear above that arrow and are cut off by the top edge of the combo box.
i also just found out that it does not happen in some pdf viewers. when viewed in adobe reader or google chrome it's fine, but when viewed in Mac Preview the inverted arrow happens.
could there be a bug in preview?
thanks for the responses guys!

A simple question about combo box

Dear All,
Just got a simple question about combo box: I have one of these selectors with labels based on filtered rows from a table.
Is it possible to have one more label that would select all options?
Like:
Product A
Product B
Product C
All Product
Many thanks for your help!
Gilles

Hi Gilles,
The purpose of ComboBox itself to select single option out of many.
For your purpose, you may have to use "List Builder" which can accomodate 1 or more to select.
Please revert for more clarification if you need.
With best wishes
BaaRaa.

HTML Combo Box Question

I generate an HTML page with a Servlet and I have a combo box that lists numbers 1-20. Depending on a parameter that is passed to the servlet I want to set the Combo box to be initalized to (display) a certain number.
Does anybody know how I can do that? (I would prefer to have the Combo Box entries remain in order)
Thanks,
Andrew

You can always put something in there like
int foo = Integer.parseInt(request.getParameter("foo"));
for(int i=1; i <= 20; i++)
out.println("<option value=\""+i+"\" "+(foo==i)?"SELECTED":"" +" >"+i+"</OPTION>");
}

JSP Combo box question

How can I make a combo box have the ability to add new items in its list? I have an existing combo box that gets its value from an SQL query. How can I let users have the ability to add to that list? If this is not possible with JSP combo boxes, any suggestions as to what field I may use? Thanks

Hello Russ9754!
Might be abit late, but I just read this thread.
Anyway...I think I have what you are looking for.
This code creates a dropdown box with the alternatives of your choice. If none of the options is good enough for the user, he/she can choose "other" and enter a more suitable choice in a pop-up javascriptprompt.
<FORM NAME="formName">
<SELECT NAME="country" onChange="countryOnChange();">
<OPTION VALUE="Albania" selected>- = Albania = -</OPTION>
<OPTION VALUE="Finland">- = Finland = -</OPTION>
<OPTION VALUE="USA">- = USA = -</OPTION>
<OPTION VALUE="Other"> Other... </
OPTION>
</SELECT>
</FORM>
<SCRIPT>
function countryOnChange(){
sel = document.formName.country.selectedIndex;
val = document.formName.country.options[sel].
value;
len = document.formName.country.length;
if (val == "Other"){
var newcountry = prompt("Enter your country.", "");
if (newcountry == null) { return; }
document.formName.country.options[sel].text = newcountry;
document.formName.country.options[sel].value = newcountry;

Simple combo box question

I have Flash MX 2004 Pro. I want to create a
movie/graphic/button ( not sure which one yet) of a county
(obviously from a state map) and I want to have all of the counties
(over 40) listed in a Combo Box. I would like the Combo box to
automatically be updated/populated every time I create a
movie/graphic/button of a county. I would like to be able to click
on a county name in the combo box and have the county highlighted.
While the graphic part is doable, I am asking for help with the
scripts.
One more thing: I have a text box that I want to have data
displayed only for the specific county. So I am thinking of
creating a text box that is invisible in the State swf but will be
viewable when the county is selected (mouse over or thru the combo
box). Do I have to use the scripts to make it viewable when the
movie is selected?
Is this even possible with my version of Flash and if so,
does anyone have some codes I can look at?
Thanks.

As far as the text goes, there are several ways to do that.
Simplest way is to make the text visible when rolled over and
invisible when rolled out. That way you get the text positioned and
formated the way you want. It isn't the best method in terms of
maintenance. A better method is have one text clip that you can
position in relation to the (x,y) coordinates of the highlighted
county and pull the text for the county from an array. The latter
requires more script but is easier to go back and change since all
you do is update an array.
I just noticed a line in the onRollOut
this[this._parent._name + "menu"].selectedIndex = 0;
that will serve you no purpose whatsoever. I missed deleting
that from the script I modified to post to you. It doesn't hurt
anything since it targets nothing you have

Question about using the Combo Box feature!

I have a form that I am trying to create for our company that will allow our field nurses to select what they need and print it more effieciently. The problem is that some of the selections are too long and I can't get the Combo box feature to allow them to be printed on multiple lines:
I have spoken to my supervisor about redoing the form to look like this:
But in order for us to meet state guidelines it has to be formated like the first because that is the state form given to us. I want to be able to either:
A) have the combo box multi-line auto text sized so it will get all the information into each box
OR
B) create text boxes at the end of the form that auto enteries the selected data from the second picture into boxes that look like the first picture.
Is there any way to do either of these?

A) No.
B) Yes. Create a text box with the following code as the custom calculation
script (assuming the name of the combo is "Combo Box1"):
event.value = this.getField("Combo Box1").value;
That way, when the user makes a selection in the combo-box, the value will
also appear in the text box. Just make sure to make the text box read-only
and set the combo-box to apply the selection immediately.

Question abt. combo box and database

Hi. I have two combo boxes, A and B. Items in A is obtained from table X, Items in B is obtained from table Y. But, the problem is that whatever appears in combo box B should not contain those in combo box A. How do i go about doing this? Note that values in table X come from values in table Y.Here's an example:
(this is I currently have)
Combo X             Combo Y
Apple            Mango
Orange           Kiwi Fruit
Pineapple        Apple
Kiwi Fruit
Mango          (this is I WANT)
Combo X                  Combo Y
Orange                  Mango
Pineapple               Kiwi Fruit
                        ApplePlease help and thanks in advance.

hi....
First of all, I've designed the two combo boxes with Add/Delete buttons in the GUI. I'm using JSP to retrieve values from database table into my combo boxes.
Actually, I have the two combo boxes already. I have already got the items inserted into combo A from table X using JSP. I am thinking of getting all the values in combo box B from the table Y first, then maybe store them in an array or something, b4 comparing those values with that from combo box A, eliminate those existing in combo box A, and the rest will be stored in combo B.
I do not know exactly how to store values i obtained from table to an array and how to compare arrays.
hope u understand what i'm trying to say, please help if possible, thanks.

Question on Combo Box

I have a form with Master (Single Record ) and Detail ( Multi Record ) blocks. There is a Combo Box in Header block. When I select a value from Combo box ( When list changed ) detail block records are to re queried. Similarly when I enter some value manulally and by pressing tab/enter key ( Key Next Item) , the detail records are to re queried.
While entering a value with Key board, the trigger When-List-Changed trigger is firing for each letter I'm typing. Is there any work around solution for this?

Quote:I think it will be nice to close the editor if we click again on the down arrow or the cell without selecting any item in the combobox, so that users can see original cell view
Your opinion collides with the opinion of other users that say they want to keep the combobox active to see what is underneath the open dropdown to open it again.
Adding your code to the iconCanvas in NatCombo breaks the behavior on clicking the down arrow. At least in my workspace. I don't know of which version we are talking about and which codebase you have. But hideDropDownControl() does not close the editor, it only hides the dropdown. This can't be the solution.
What you need is to override mouseDown() to close the editor instead of hiding it.
BTW, with this change you remove the ability to move the focus to the text control to allow editing.

Silver Combo Box Display Style Bug

[LV2011, Windows XP]
There appears to be a small bug with the Silver-style Combo Box control when you right-click and select Visible Items->Display Style. For the string control a glyph appears properly, but for the combo box the glyph appears in the wrong place, and the colours are wrong. In fact, the glyph only appears properly if you click on it, or do something else to force a redraw of the control.
This combo box is a bit confusing, since it has no "Radix Shadow" part like the string control does, and in fact only the Silver-style combo box lets you display the "Display Type" glyph. The other styles of combo box have no "Display Type" feature in the "Visible Items" menu, but the "Display Style Visible" checkbox does appear on the "Appearance" tab of the Properties dialog box (though checking it has no effect, and it appears unchecked if you re-launch the dialog box".
I've attached a new version of the control which is close to fixing the bug, but the glyph region is 1 pixel skinnier than the string version. Copy this to your "..\vi.lib\silver_ctls\String" folder if you want it to replace the version in the palettes.

Jaegen:
Good catch, there is now a Corrective Action Request filed for this issue. It is correct that this property is
not supported by the Combo Box found in the Modern Palette. However, this should at least be documented in the
"Display Style Visible" property documentation if this is case, which it is not.
Thanks for alerting us to this error and if you would like to follow the CAR, look for CAR# 312717 listed in
bug fix reports for later releases of LabVIEW.
Please let me know if you have any questions or need any more help with this issue.

How can I make the combo box turn to the value of black.

When the show button is pressed (and not before), a filled black square should be
displayed in the display area. The combo box (or drop down list) that enables the user to choose the colour of
the displayed shape and the altering should take effect immediately.When the show button is pressed,
the image should immediately revert to the black square, the combo box should show the value that
correspond to the black.
Now ,the problem is: after I pressed show button, the image is reverted to the black square,but I don't know
how can I make the combo box turn to the value of black.
Any help or hint?Thanks a lot!
