Checkbox in front of formitem label

Hi,
I use flex 3 to design a form, i want a check box before every label, i tried without setting label property in formitem but the component alignment is not good as below
is there a way to add check box before the label or is there anyother layout that will suit for this requirement. Please provide me a sample code if possible
thanks
prasad

Prasad,
Add label property to the checkbox.
checkout this below example:
<?xml version="1.0"?>

<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml">
 <mx:Form>
 <mx:FormItem label="Subscribe">
 <mx:CheckBox label="Subscribe?"
 click="emAddr.required=!emAddr.required;"/>
 </mx:FormItem>
 <mx:FormItem id="emAddr" label="E-mail Address">
 <mx:TextInput id="emailAddr"/>
 </mx:FormItem>
 </mx:Form>
</mx:Application>

Make FormItem label text word wrap?

I am building a form, but my labels are fairly long
sentences. Is there a way to make the FormItem labels wrap? I tried
defining the labelWidth, but it just truncates the text with "..."
If there is no way to add a break in the label or make it
wrap, what is the best way to do this? With a bunch of
HBox's?

That's not entirely true. If you use the mx_internal
namespace you can modify the Label's internal UITextField and
enable wrapping. Something like:
formItem.itemLabel.mx_internal::getTextField().wordWrap =
true;

FormItem label - moving with paddingTop

i have been trying to line up a formItem label with my custom
fields and have discovered that with comboBoxes or textInput
fields, you can move the y location of the formItem label to line
up horizontally with the comboBox/textInput textfield with the
'paddingTop' property (of the comboBox/textInput component).
This is great, however moving the formItem label with the
field paddingTop property doesn't work with:
dateFields, as they don't have a paddingTop property,
a custom field that i created based on a HBox,
or TextArea fields
My question - is there an alternative way to move a formItem
label in the y direction?
(the reason i ask is that the label isn't sitting nicely
aligned with my custom fields)

Probably not the response you want, but...
Don't use Form. I never have because it is too inflexible,
and provides too little benefit.

Button to enable all checkboxes on front panel

I have checkbox controls on the front panel to select various functions of my VI. I would like to have buttons to check ("enable all") and un-check ("disable all") all the checkboxes at once, if desired. Preferably, I'd like to see the boxes activate (show the checkmark) prior to starting the VI -- like they do when you select them one by one. I am fairly new to LabView & am using 7.0 Pro. Any help would be appreciated.

Here's a picture of the code. Pretty simple.

FormItem label left align issue

hi experts,
I am very new to Flex. I am using Flex API and i have some issue with FormItem. I cannot make the labels left align. I found a style in web which is as follows.
<mx:Style>
.rightAlignedLabels {
text-align: center;
FormItem {
labelStyleName:rightAlignedLabels;
</mx:Style>
I want this to be used in my action script.But i do not understand to set this style via the API methods. I tried different ways as follows.
new FormItem().setStyle(..,..);
But still i coudn't figure it out. Please can sombody help.
Thanks,
Harshi

FormItem
labelStyleName : myFormItemLabelStyleName;
.myFormItemLabelStyleName
text-align : left;

Edit Disable Panel Grid Alignment does not affect the Positioning of Front Panel Labels

In LabVIEW 2010, when I choose Edit>> Disable Panel Grid Alignment the positioning of Front Panel objects gets much finer so that I can make small adjustments. Put it does not seem to affect the positioning of front panel object labels. These object labels still move in very coarse increments and do not allow me to position them carefully.
How do I turn off the Grid Panel alignment for Front Panel Labels?

The positioning of labels you encounter has not so much to do with any grid, but with the fact that for labels, LabVIEW attempts to snap them to one of the control corners if you get close enough to the owning control. Outside of a certain range of the owning control you should be able to place them easily on any pixel. The snap behaviour of owned objects is not configured through the panel grid option. I'm not aware of an option to disable this behaviour, but usually find it rather handy instead of annoying. If it happens to not be exactly as desired, I adjust with the label selected and using the cursor keys.

How do I get the Label for a Front Panel Control to appear in the Block Diagram but not on the Front Panel?

How do I get the Label for a Front Panel Control to appear in the Block Diagram but not on the Front Panel? On the Front Panel I am making a complex control that consists of a Slider and a Numerical Input box. Both Controls display the same information and either can be used for Input. When one changs, the other is made to display the same value.
But I only want the Slider to display the Label on the Front Panel, to avoid confusion. On the Block Diagram however, I want both controls to display their Labels so that I know what they are. How do I display the Label for a Control on the Block diagram, but not display its Label on the Front Panel?

No. The Label Visible property is separate for the front panel control label and the block diagram terminal label.
How did you start out with the block diagram's label not being visible? Whenever I drop a control or indicator, the label is always visible on both the FP and BD by default. Maybe there is a LabVIEW option that causes new controls/indicators not to have their labels visible by default, but I have yet to find it. I don't think an item should ever be dropped without the label visible, good LabVIEW coding practice demands that the labels for control terminals on the block diagram be visible so that you know what control or indicator a wire is going to.
That being said, I have seen a lot of VI's posted where the label for the terminal on the BD is not shown (against good programming practice.) I've gone to the BD and right clicked to show the label. Sometimes, the people have an empty label (which will turn off the visibility for both the FP and BD) and I'm forced to add some text of my own into the label so I can figure out what their code is doing. When I add some text to the label, at that time, I find both the BD and FP labels become visible.
Are you dealing with controls that have empty labels to start?
Good programming practices:
1. Always have a name for all of your controls, never use and empty label by deleting the text in the label.
2. Make the labels unique. For example, don't have two controls both called Stop. How do you know quickly know which terminal relates to which control?
3. Always show the labels on the block diagram, so you know the function of a control's terminal. If you want to hide the label on the FP, that's okay.
4. If you want a different label to appear on the FP than whatever you actually called the control, then use the caption. You can hide the label and show the caption. This is useful if you need to programmatically change what the "label" is on the front panel such if you are making an application that needs to change its user interface such as for a foreign language.

How can I get label of Checkbox?

Hi,
I have created the following checkboxes
private Checkbox playingCB, recordingCB, playbackCB;
private CheckboxGroup cbg;
playbackCB = new Checkbox("Playback mode", cbg, false);
I'm trying to get the "Playback mode" label in my actionPerformed(ActionEvent event) method
I have tried the getActionCommand() but it didn't work on Checkbox
It works on getting label of Button
How can I solve this problem when I really need to do it with actionPerformed method?
Thx
jojo

I don't know for sure, but having looked at the API documentation (http://java.sun.com/j2se/1.4.2/docs/api/) I'd guess.......
Checkbox selectedCheckBox = cbg.getSelectedCheckbox();
selectedCheckBox.getLabel();So maybe you need to pass your event handling class constructor a CheckboxGroup object, so you can then call the above code?

Checkbox Group Labels

Hi
I am Created checkbox group called "Gender".Automatically there are 3 checkboxes created with this with labels as "Lebel1","Label2","Label3".Now i want to change "Label1","Label2","Label3" as "Male","Femele","NotSpecified".At design time how to change these labels.I tried to change the "texts" property.can anybody help me?
Thanks
Prasad

Hi Armin,
I am trying to create a Checkbox group. I created a value attribute and binded it to simple datatype containg list of items in enumeration. Then I binded the Checkbox group "texts" property with the value attribute.
In the layout wizard all items are visible but at runtime none of them is visible.
Cardinality of node containing the value arrtibute is 0..n. I have checked it for 1..n also.
Please tell me what could be the possible reason behind it.
thanks in advance!

Custom DefaultTreeCellRender not rending node labels correctly.

In our JTree we need to display the state of our custom nodes, the state can be cycled by the user clicking on the node. Our problem is that since upgrading from Java 1.4 if a node is clicked before it is expanded the child nodes will not be rendered correclty, some nodes may not have the label showing, some may not have the label or icon showing.
Under Java 1.4 the following code works correctly.
Under Java 1.5 and 1.6 If you click on a node before expanding it (which changes the node's icon) then expand the node the child nodes are not completely rendered, some may be missing a icon or label or both.

I can't recreate your problem. I'm running 1.5.0_09. When I open the program and JUST expand the nodes I see all "file" icons and all the labels work correctly. If i Select a node before expanding it, I get the same result.
What Am I supposed to witness happening?

thank you!
I want to have a combobox with checkbox as item, I rewrite a render writen by ice, because the combobox has three state, when I click diferent checkbox in this combobox , the label of combobox will update rightly, but if I click one checkbox to change the checkbox state ,the label will no update , it seem that when I click one checkbox many times .the menthod

You are updating the label value when (index == -1), let change into (index<=0).
like below
// this should cause a JComboBox to paint the Label instead of the
 // check box + label combination
 if (index <= 0) {
 Vector v = new Vector();
 v = getSelectedObjects();
 String val = generateString();
 JLabel label = new JLabel(val);
 if (iconLabel.getIcon() != null) {
 label.setIcon(iconLabel.getIcon());
 System.out.println("label");
 return label;
 }

Using currentTarget.label as variable in path?

I have the following code:
<s:FormItem label="First" click="onItemFocus(event)">
 <s:TextInput id="First" enabled="false" text="some text here..."/>
</s:FormItem>
Which when you click the FormItem it fires this function:
protected function onItemFocus(e:MouseEvent):void
 var targetname:String = e.currentTarget.label;
 First.enabled = true;
 First.setFocus();
 First.selectAll();
Now as you can see the targetname variable value is 'First' and the ID of the textfield is 'First' so the next part of the question is, how do I use the targetname variable as the name of the component I wish to enable?
I was advised that I could do it with square brackets like:
[targetname]enabled = true; but I can't make that work, and as I have about 50 fields that need this setting an efficient way would be great.
The other possibility I have is if I can set a style for the the normal state, and then a different style for the normal w/focus??? Now that would be awsome as this would alow tabbing between fields too, which would be better under certain circumstances.
Thanks for any help you can provide.

In main request, add navigation on department column or values. Then, you must have target request with filter "Is prompted" on department column.

Accessing S:List Checkbox Item Renderer Outside the Renderer

Hi All,
I have an S:List, with a checkbox item renderer. I was to be able to access the selected portion of the renderer to create a new function that at the press of a button this will delect all the current selected items in the list.
Doco states that i should be able to do this just by setting the selectedIndex to -1. But not sure if this is specific to 4.5?? But it is not working for me.
Below is my current list. Outside of this list flashbuilder does not know about chkList, or even selected. How can i get access to this to deslect all?
<s:List
id="ltattributes">
<s:itemRenderer>
<fx:Component>
<s:ItemRenderer>
<fx:Script>
<![CDATA[
import mx.events.ItemClickEvent;
protected function chkList_changeHandler(event:Event):void
var e:ItemClickEvent = new ItemClickEvent(ItemClickEvent.ITEM_CLICK, true);
data.selected = event.currentTarget.selected;
e.item = data;
e.index = itemIndex;
dispatchEvent(e);
]]>
</fx:Script>
<s:CheckBox id="chkList" selected="false" label="{data.displayname}" change="chkList_changeHandler(event)"/>
</s:ItemRenderer>
</fx:Component>
</s:itemRenderer>
Thanks

Try: dataGroup.getElementAt().

How to remove labels from text fields?

Hey Everyone!
I am having troubles with forms in Dreamweaver CC.
I insert a text field in a form but the text field automatically comes with a label.
How do i stop this?

And I get that!
But say I insert a text field.
It is preceded by a label saying "Text Field 1:"
But I already have written what the text field is supposed to do!
And when I go in front of the label and press backspace, it doesn't wanna get deleted; not until I have to select the text and delete it!
So you see a large part of my time is getting wasted in formatting the page and i can't give my full attention to the php code I want to write as I get frustrated because of this!
So if you could help me get rid of the labels for good ; it'll be amazing!
Thanks
Regards
Anuj

Html next to cfinput checkbox text

I have a form which requires two a href links and surrounding
text to appear to the right of a checkbox. When I put the html next
to the closing tag, it does not display at all. When I place it in
the label property, it shows the links as plain text. When I put
the text in cfset tag outside the form, then call it from the label
tag, again, it shows up as plain text. Is there any way to combine
this the certification HTML with the checkbox so it will display
properly?
Line of code:
<cfinput checked="yes" type="checkbox" name="ICertify"
id="ICertify" label=#icertify# />
Output:
I certify that all information furnished is accurate and
truthful. I also certify that I have read <a href="
http://www.usps.com/ibip/html/privacy_act1974.html"
target="_blank">The USPS Privacy Act Statement</a> and
<a href="
http://www.usps.com/ibip/html/privacy.html"
target="_blank">PC Postage Privacy Principles</a>.
I'm brand new at ColdFusion, so be gentle in your answer.
Thank you,
Ernie

Thank you for your help.
I copied the code directly from your message, then tried
several variations, including typing the text directly in between
the label tags, excluding the <a> tags, etc.
This is still not working - the text is not displaying where
it should and in the way it should. I can't understand what's
blocking the label from displaying.
When I place the #icertify# cfset reference anywhere outside
the form tags (enclosed in <cfoutput> tags), it returns
exactly what I want - the text with clickable links. It seems that
within the form, though, it won't function at all.
I haven't made any changes to the original code posted last
week. If there is anything in there that might be suppressing it
from working, let me know.
Thank you,
Ernie
