Actionscript 3 :: Flex 4: Have A Drop Down List Of Checkboxes?
Oct 12, 2010
How would I get a drop downlist to populate with check boxes. I am porting a c# project to flex, and I would like to imitate the functionality of their checkbox drop list.
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?
I have a List with an item renderer and would like to enable drag-and-drop onto the items in the list, rather than adding the data to the list. Is it possible to find the item that is being hovered over when dragging?
I have set up some lists (<mx:List>) in Flex... I have drag and drop working fine, in that I can move elements easily from list to list. For some reason though, my DragInitiator and the currentTarget of my event are the same... even though I am obviously moving from list to list... Does anyone have an example of a function that I can call on my "dragComplete" event that will tell me the current target which will give me the id of the List object I am dropping on?This is my current function which is always returning true...
Code: private function _dropped(e:DragEvent):void {
I am trying to implement a drag and drop function between a list control and a columnchart in Flex3. List items should, when dragged and dropped on the chart, be displayed raphically in the columnchart.Alas, dropping the listitems on the chart does not seem to result in a proper graph.Here my code till so far with regard to the drop part:
private function doDragDrop(event:DragEvent):void{ var ds:DragSource = event.dragSource; var dropTarget:ChartBase=ChartBase(event.currentTarget);
I have this project for school where i have to populate a drop down list control from an xml file.I mange to do that for a label/text input control, but i can't seem to do that on a drop down.I get this error any time i tell him to "additem" with an xml query (not getting it with simple text):"#1009 Cannot access a property or method of a null object reference"[code]...
When a combobox is elected in the flex app, there is a quick flicker, then the combobox needs to be selected again in order to get the dropdown to open. After that, the dropdown works as expected, but only while selecting the control subsequent times while on the form. Reloading the form requires the double selection again.
I just started using Flash Builder 4 (yesterday infact).
I have two lists and a canvas. When dropping a list item onto the canvas, i want to trace what item it is (the label and data) and which list it came from. From there, i want to add an image to the canvas according to the dropped item.
Here's my current code
private function componentDragEnterHandler(event:DragEvent):void { DragManager.acceptDragDrop(Canvas(event.currentTarget)); DragManager.showFeedback( DragManager.COPY ); }
I'm using drag and drop on a DataGrid to reorder items. However, when the user holds down Ctrl he can initiate a drag Copy operation. How can I disable copying altogether? (not just cancel the drop, but also prevent Ctrl + drag from showing the (+) icon)
I wish to have a standard row with string items except two items,no 1 there is a date field and I need a date selector for it.no 2 in another cell of the row I want to put a drop down list box containing text "40" and "20" or you can manually edit the cell so that it displays what ever input you decide (other than 40 and 20)
I'm dragging from a TileList to a custom component. I want to know what is being dragged before I accept it. How do I set the "format" that is used for "event.dragSource.formats" in the DragEvent?
Edit for clarification: When you set "dragEnabled=true" on the TileList, it takes care of the drag source stuff, but it uses "items" as the format for the DragEvent. I'm looking for a way to have the TileList use the correct format.
I am developing a form for handling access rights in a project.I use VsflexGrid7.0 and also Vb6.0.I thought that it would be good when I show 1 (has access) and 0 (doesn't have) via checkbox within my vsflexgrid(vsflexgrid1).Now, my problem is when I click on a checkbox for Insert access right, how to get control it's value ?
I have a slightly complex flex script, People.mxml. In the PersonAdd state, I have a form which will be used to send data to the mysql server. In that form , I have a repeater that will create a checkbox for every department in my database. When I click the Add button, I want to insert data into the people and people_departments tables.
[Code]...
[Edit] I am using an s:Checkbox and I do not have the data property. mx:Checkbox does but I cannot use the mx:Checkbox component in my project.
I want to make a drop down list menu which open when mouse-over not click as you can see I use
<sropDownList id="dl" rollOver="dl.openDropDown()" but the problem appears when I try to close it.I can't use this rollOut="dl.CloseDropDown()" because It will close too soon(When It open I've tried to move my mouse down to the sub-item but the list will close if I move to somewhere else that's not a list base so I can't select the item on the list because it close before I can)
I'm looking for a way to drag names from a scrollable list and drop them into another area.From what I've read, it doesn't seem like I can use the List component if I want to achieve this, but I'm having trouble thinking of a way.Basically, I'm going to have a input text box that will be used to be populate the list. Then I would like the ability to drag the names from the list to a blank area.I was able to get it working with the input text box to populate the list, it was just the dragging part that caused me trouble.
I am trying to build a dropdown list of fonts with each item in the list being written in its font ("Arial" is in arial, "Comic Sans" is in Comic Sans, etc.). What is the best way to do this? Here is the latest code that I have attempted:
I have two spark lists,backed up by Array Collections, both of which accept drag & drop either to move objects between them or to reorder within the lists. I have a method which is called on drop which resets some properties of the object to 0, this works as expected...
protected function list_dragDropHandler(event:DragEvent):void { if(event.action != DragManager.NONE) {
[Code].....
What I would like to do is only call this method only when the objects are moved to another list, currently it is called when I reorder within the same list too
I have a combo box on the stage in a main SWF. when the user selects an item in the dropdown list a child SWF is launched into level0 using loadMovieNum and data is left behind using _global variables for the child SWF to use. this works fine and well. but inside the new child SWF that is launched is a button that takes you back to the previous main SWF with the ComboBox. its done using the same method loadMovieNum into level0. and the main SWF loads but you cannot open the ComboBox. it will not drop down. the halo green color on hover over is there and it gets darker when you click, but the list doesn't drop down. here is some code that I think may be significant to the situation...
Because of screen size, I must ensure we're only displaying necessary data to the user.I have a drop down box that contains only 5 items and I would like that when an item is selected, it doesn't appear in the drop down box (since technically it's showing twice, once at the top as the selected item and once in the list). how I would achieve this? I tried using a custom CellRender and overriding the "set selected" function to call this.visible = false if selected is true, but that simply hides the item but does not remove it from the layout of the drop down list.
I'm using a Spark List with a TextInput in the ItemRenderer, with ability for the user to reorder the list rows by drag'n'dropping them. This is how I declared the list :
Everything works fine, except that it's impossible to select the text in the TextInput with the mouse, instead it's dragging the row...How can I set the TextInput to have priority over drag'n'drop ?
i'm trying to repopulate a list when you select a new category from a drop down component.
So far i can populate the category drop down and i can also populate the list box from a default dir but i can't seem to get the list to change when you select a new category.
this is the category script that populates the drop down (this is working fine except that when i change the category i want the list box (bgList) to repopulate with the new location files):
