Flex :: Displaying More Than 5 Things At A Time In A DropDown (ComboBox)?
Sep 17, 2009
I have a ComboBox in Flex with about 20 items. How do I display all of them in a dropdown with no scroll bar? Right now, Flex displays 5 at a time in the dropdown and puts a scrollbar to scroll for more.Here's an example:
http:[url].........How do I make the dropdown bigger in this example so it shows all 10 items at once?
Short version: ComboBox's dropdown works and renders properly before fullscreen, but not during or after. I'm not totally sure how to ask this, so I've actually made a page demonstrating the error, with a very simple Flex app, and all three directions you need to experience the problem yourself.
For those of you not daring enough to follow my link above, I'll do my best to explain here. I've built a rather extensive Flex application (not the one in the link) that has some graphs and charts and checkboxes and other controls for those charts. At the bottom of app in a few of the application States, there is a ComboBox (like a <select> tag in HTML). Because this is at the very bottom, when you click it to access it's dropdown menu, Flex thoughtfully has it come out of the top.
I'm trying to change the position of the dropdown list relative to the combobox item.Setting the position using comboBox.dropdown.x = 1337; doesn't work...
Background: I am doing some UI work where I allow the user to programatically add and resize controls on a canvas. Problem: When resizing a combo box through AS the dropdown stays at the same width as the first time it drops down. So user places combo box on the page, clicks the down arrow, sees the options, selects an option or clicks down arrow again to close, resizes the width of the drop down, clicks the down arrow. Now drop down is the same width as original. Have tried simple things like setting the width of the dropdown specifically and invalidating display list but it still doesn't work.
I've been working on an application (with ComboBoxes) that requires scaling the entire application based on screen resolution. I thought it would simply require changing the "scaleX" and "scaleY" properties of the top-level application, but discovered that the ComboBox dropdown doesn't appear to scale accordingly, as in the following example:
which results in the dropdown appearing (sliding down) unscaled until it reaches it's extended length and stops at which point it scales up and remains at that scale until it is closed. I have also found that if you call "invalidateDisplayList()" on the comboBox or the dropdown, then it undoes the scaling, so it appears that whenever the updateDisplayList is called, the dropdown only applies it's parent ComboBox's scaling, and not the ComboBox's parent container's scaling.
I understand that, as a pop-up, the dropdown isn't in the Application's or ComboBox's displayList tree, which appears to be the root of the problem (no pun intended).
The renderer shows html text properly in the drop down list, but in the top most option (selected item) the whole HTML tag is shown instead of what the tag represents.
I seem to have is that the Autocomplete component that seems to be part of flex extras is not displaying the list of items in the dropdown list. Basically, I get a list of blank items. I know they are there and they are the right items because as soon as I click on one, I get the right text in the combobox.
Again, when I type "T" in the text box I see a dropdown list with 3 empty items. Clicking on the third item puts "Test3" in the textbox. But the items themselves are not visible.
It almost as if its a font/foreground color thing, but I've played around with some of those settings too with no success.
i inserted a dateField component.on clicking it displays calender, i would like to add 2 comboboxes, i shows hours(0 to 23) other for minutes (0 to 59) to calender so tht the user can select the time along with the date and that wil be displayed in the text input as date and Time. one more thing i would like to add is clear button to clear the selected date to the calender.
I've been playing with s:ComboBox and generally like them a lot. One detail is driving me nuts though - most likely due to my lack of knowledge in the subject - is that if I try to add a new item to my dataprovider in a changeHandler (registered to the change event) the text for the ComboBox textInput disappears - although the item addition works perfectly. Interestingly enough the same operation works fine if it gets called by clicking on a button, i.e. post the change event has been processed, and the text does not disappear.[code]if you take out the change handler you will see that adding a new item and then clicking on the button keeps the new element in the textInput while adding the item to the data provider, which does not happen if you just enter a new item and press enter.
I have a menu movieclip that has 800 x 22 px i need to embed this flash menu in a jsp page and make that the displayed menus got outside of this size and overlay the contents of jsp. kinda of what does the menus of the adobe page
is there any working solution to make dropdown semi-transparent in Flash CS4?tablebox.dropdown.setStyle("backgroundAlpha", 0.33);doesn't work and return no errors.
I'm working on a sort of AutoComplete component and faced one problem. When you create a new instance of a component, fill it with data - everything seems to be ok. When user types a letter in the inputField (and filter accepts one or few records) - everything goes alright, BUT if the first time user types a wrong letter (filter returned 0 records) - I'm getting a null-pointer exception.
This component is based on ComboBox. I have some thoughts about that: I suppose that the dropdown is not being created at time, any ideas on how to force my autoComplete to create it? I know 1 way - copy/paste some incapsulated code from ComboBox class .. but it would be too many of it .. I'm looking for a better solution.
preventing combobox dropdown - I create own component FileOpenDialog - using FileReference - but list always start dropdown before FileReference.brows() appear ?
I remember I had this problem also on AS2: if you load a .swf that contains a combobox, into a mc in the main .swf, and you try to manipulate the scale of this container mc, the combobox dropdown menu won't resize.In AS2 i solved it by puting the combobox inside a mc "container" that also contains the code line this._lockroot=true;, and attaching this "container" to the swf using the attachMovie() method. I don't know why, but it worked, and when i loaded this swf into a mc in the main swf and re-scaled that mc the combobox's dropmenu scaled together with it.
I want to create a Custom ComboBox in which the DropDown contains the Horizontal Line or you can say HRule immediate after the First Item. here I am providing you the image For that you can see I have used paint to draw the HRule I want component similar like that.
I want to show some different-2(dynamic) icon in my combo Box drop down list. I am able to show icon in combo box list but I want to change the color of this icon for different-2 values.
Here is ActionScript Code: for(i=0;i<len;i++){ newColor = "0x"+_root.colorList.items[i].ColorCode; labelText = _root.colorList.items[i].DeptCodeComboDesc; comboClip.clip.opaqueBackground = parseInt(newColor); _root.colorListCombo.addItem({label:labelText,pIcon:"comboClip"});
"comboClip" is a clip which I want to show as icon in combobox.
I have one button, that when clicked should display several images, one at a time. At the minute they are all just coming on together, how do i seperate the functions so they come on individually, for example like bullet points, e.g click once and image1 appears, click again and image2 appears etc... so eventually all of the images are on screen, but they don't all just appear together, if that makes sense!
I've been trying to use random to make something happen a certain percentage of the time. For example, for making the scientist go to frame 91 half the time and 181 the other half, I was using this code:
I have a textfield, a combobox and a textfield displaying the XML.When I add something to the XML file using the textfield and the combobox, the textfield displaying the XML goes black.
In my game, Ive got a HUD, (heads up display, life bar, points scorer etc...) and when an enemy comes onto the stage, the lifebar is appearing behind everything else, and it should really be the thing that's infront of everything else. Is there like a line of code and a function or variable I should declare or import that allows me to create depth and put my lifebar at the front.
I am trying to create rollovers in dropdown menus that i have. I am having a problem with the rollovers on the same dropdown all playing at the same time. The rollovers play backward and forward correctly as they should but when you mouse over one of seven they all play.

I'm trying to set a specific list item in a mx combobox to have a custom item renderer, the problem is that I cannot do this via mxml, it needs to be done via actionscript at a later stage, eg: combobox gets created, combobox gets populated, user does other tasks, combobox needs to set one or more items in the combobox to have icons (via item renderer)..
I can do this via the onChange event, but it only applies the icon when the combobox is opened and there is a slight delay so you can see the icon being added.
