I am trying to implement a list of checkboxes and a Android Form App I am working on. I want the list to only have single selection, i.e. I can only select one option from the list.... for some reason I can not find any code to do this, I am using Flashbuilder and the Flex framework, anyone know of a way to do this ??
Thanks in advance for any help!
If you want a single selection, use radio buttons with a radio button group.
The only reason you'd want to use checkboxes is if you want to turn off all selections (with radio buttons, once you've clicked a button one is always selected).
If you still want to use checkboxes, do the following:
onCheckBoxSelected(e:Event){
for each(checkbox:CheckBox in collectionOfCheckBoxes){
if(checkbox != e.currentTarget){
checkbox.selected=false;
}
}
}

I am using bokeh single radio button with single title . Initially it is inactive and when i click on radio button it changed to active but if I click again in active it is not changing to inactive state.
How i need to acheive this functionality??
Whether it's RadioGroup or RadioButtonGroup, neither of those two widgets is meant for a single element usage. Per design they are meant to be used as a group of elements. I advice you to use Toggle for your application. Other alternatives are CheckboxButtonGroup and CheckboxGroup. See Bokeh documentation for specific examples.
I am new in Xamarin forms and I need to implement a table in Xamarin forms. Requirement is-
Initially table will be empty and has four columns. After feeling form and clicking on submit button, new entry will be added in table. First column is Test, second column is single radio button, third column is again single radio button and forth column is button to delete that row it self.
I need to know which approach will be suitable to implement this requirement. Is it grid layout or tableview or something else.
Consider Table View use cases vs List View use cases. Table views are meant for static content. You should really consider a list view for dynamic content. (like adding a row with views) Being new to Xamarin.Forms, you should take the time to read completely through the documentation as (at least for me) it wasn't straightforward. Also, consider a WebView as radio buttons are not going to play nicely across platforms, and your problem would be easily solvable with jQuery.
I have an app built in Unity which uses the new canvas features including buttons and inputfields.
I'm wondering how I could implement automated testing by programmatically entering characters into the input fields and clicking buttons.
In the case of the button the UI.Button component doesnt seem to have a click method you can call.
Is there a way of registering mouse clicks at the buttons location? Or some other way of achieving this?
Ok, This is how you click a button programmatically
MyButton.onClick.Invoke();
and for the inputfields you can just set their text fields like so..
MyInput.text = "flooopybloopybloo";
I want to add radio button in my drupal view ?
I need to make a table of users and set for each of them one status(present,absent,delayed,...) by use of radio buttons, and A button under the table to save these statuses.
So how can I change view?
Mohsen,
Maybe Views Bulk Operations module can help you. You can download it at http://drupal.org/project/views_bulk_operations.
I used embed form module to add some radio buttons in my view. and now I must implement submission.
I wish I new.
I'm currently playing with hook_views_data to create a relationship within Views between my table and a node. This works ok.
I just need to work out how to make this data submittable from within the View.
If I work it out I'll let you know.
I have a list control and i want the user to be able to select many items at a time. Thus I want it to act that if the control key is pressed while he is clicking. Eg if he clicks on a selected row it should become unselected and if he clicks on a unselected row it should become selected.
Do you have any idea how to do this?
Thanks,
Dennis
If you want to follow standard UI Precedent; then set allowMultipleSelection to true and teach your users to use the control and/or shift button to select multiple items.
If you want to select multiple items without having the using press the shift or control button you'll have to extend the List class. I did a sample a while ago using the DataGrid:

You can probably use the same technique with a List. But, I don't recommend this approach.
