ActionScript 2.0 :: Combobox Won't Allow Selection Of 1st Item?
Oct 18, 2009
Like the title says I can't seem to get my combobox to allow the first item to be selected after loading.If I select any other item in the list it works fine and I can immediately come back and select the first.Seems like strange behavior but as this is my first project using the combobox I'm hoping it's something I've overlooked or just didn't realize I needed.Here is the code I'm using
I'm creating a mobile app in which I need to show a calendar with months at the top. The months are part of a component that extends from SkinnableDataContainer (and has some custom scrolling/behaviour - which is why I did'nt use a spark list). I need the months to be shown as a 'trapezium' shaped tab and so I'm using a png image as a mask in the item renderer for the component.
When the mask is not applied, it all works well - the months render, the list/data container selection works when I click on a month and so on.When the mask is applied, it renders well, scrolling and everything else seems to work well - but when I click on a month, nothing happens visually. And from the trace statements in my code, it appears list item selection is not changing. Looks like mouse clicks are not working.
Code:
public class TopCalendarMonthRenderer extends LabelItemRenderer { [Embed(source="/assets/trapezium_alpha.png")] private static var TrapeziumMask:Class; private static var trapeziumMaskInstance:BitmapAsset;
I have made a flash player that get the movie from a seperate server. There are also some slideshows that depending on time in the movie chances so the pictures are relevant with what you are watching., this pictures chanses with the from a xml file. I would now also like a Combobox that works as a chapter selecter. I have "made" the combobox and the text that i have in the xml shows up however now i cant get the combobox to work
I have a combobox with multi selection. when i click on add button, which ever data is selected in the Combobox, those data has to be displayed in the another comboBox.
Is it possible to use AS2 to dynamically set the current state of a ComboBox?I'm loading variables from an external file, and I need the ComboBoxes to reflect the selection that comes in.
I'm trying to make a simple drop down list where each selection has its own value. I have a combobox with the following parameters. Editable = false Labels = choice1, choice2 Data = 0,1 Row Count = 8 Change Handler = blank
I have an instance name of "type" on the component. Now I have a dynamic text field with a var of "price" and on the first frame of my movie I have this code if (_root.type == 0) { _root.price = 10; } if (_root.type == 1) { _root.price = 20; } But its not showing these values in my text field when I select those choices.
I have a datagrid.In this datagrid I have a combobox item editor. This datagrid also has multiple columns where a user inputs numbers in each column. These numbers are then calculated by formula where the sum is posted in the "total" column. In this combobox there are two options for the user to choose from and each option has a different formula for calculating the inputted numbers. What I want is for when a user chooses "option 1" one formula is used to do the calculation, when "option 2" is chosen by the user then formula two is used to the calculation.Here's an example:
Combobox Option 1 (formula 1) is chosen by user = (Column2 - Column1) x column3 = "total" column Combobox Option 2 (formula 2) is chosen by user = (Column1 - Column2) x column3 ="total" column
I realize you would use a conditional such as "if else" statement, but im just not sure how to do it. I've been trying to implement this for a while with no success.
Do you have idea about the reason for that error and how to prevent it? N.B. The code that triggers this error is as a result for click handler. If before encountering this error change the selection on my yearsCb, everithing is fine. EDIT: I forget to specify that this error is thrown when it is a selected item in my ComboBox. It seem that after container that holds the ComboBox loses the focus, it doesn't recognize it's ComboBox child as having a selected item anyway (this problem arise only after the modal popup close.).
I am building a website for an online store in Flash 8. I needed to use a dropdown menu for selecting the size of a clothing item, so I just used the default ComboBox component. I thought it was working fine, until I came across a strange bug (with the component, or my own code) where the ComboBox was not showing the current selected item.
The dropdown's list works, and shows all the options, but if you click on one, it doesn't get displayed as the current selection in its TextBox. The weird thing is that it still works fine, and I can access the data ok. If I use myComboBox.text I can access the current selections text, even though Nothing is being displayed.
Has anyone come across this before, and has any suggestions for what I am doing wrong.
A few details: Here is the actual code I am using to load the options into the ComboBox: Code: Select allvar my_cb:ComboBox = this.pages.product.size_comboBox; my_cb.removeAll();
var sizesList:Object = productData[categoryID][productID]["sizes"]; for(var s in sizesList){ my_cb.addItem({data:s, label:sizesList[s]}); } my_cb.redraw();
There are a number of other things happening the same time as its adding the items to the comboBox, e.g. loading images, creating movieClips, etc. Could loading this be causing the comboBox to not function properly.
I'am trying to create a Flex Application where users can select courses from a combo box based on the department that offers the course. The combo box has an XML variable as its data provider and has the different departments listed. When a user selects the department from the combo box the courses offered for that department should automatically update (show up) in the data grid under their respective columns. What it needs to do is retrieve the XML for the selected department and then set the data provider for the srcgrid accordingly. I am having a lot of trouble with things displaying correctly in the data grid. The course should be under Course ID, course name under Name, etc...

We've all been to driver download pages where you select your model from one combobox list and then that choice populates the next combobox of choices and then that combobox choice spawns a link to the driver.Combobox 1 will display a list of 14 items. Each item in that list has a subset of 3-4 items that will appear in combobox 2 once a selection is made. Then when a selection is made in combobox 2 a link will appear for a download
I have 4 items on the stage item1_mc, item2_mc, etc...they're stacked vertically with a small space between them. I wish to cycle through these items with two keys, up and down respectively...My current idea is to create an array of these items and have each press of the key add or subtract "1" from the current selection..
In my TileList, I want to select the TileList items on rollover, as opposed to the click event. I already have the TileList setup to allowMultipleSelection = "true".
I've got a comboBox with defined data and label fields. On Event.CHANGE I capture the data field. I need the comboBox to default back to the user selection if they should navigate to another screen and then come back. Normally I've got an array of labels that I can use to just lookup the index: comboBox.selectedIndex = labelArray.indexOf(user selection); In this case I don't have labelArray. What I really want to do is something like this (only with real AS, not fake):
comboBox.selectedData = storedDataString or, if the data array is accessible: comboBox.selectedIndex = comboBox.data.indexOf(user selection); Is there an easy way to do this, or should I just suck it up and add yet another global label array?
I trying to populate a combobox from a .php file and return the values of the selection. I have the .php set up to where it outputs something like
&artists=anartist,anartist2,anartist3, etc..they have names..I already have the combobox set up to where it displays
anartist anartist2 anartist3
after you click the dropdown arrow..How would I get it to return a the numerical value for the artist (ex: anartist would be "0" since it is first in the list) and put it into a variable so that when it is selected it could be placed into an eval() function to create a variable such as "albumcover0" to be loaded through a function. I have been reading tutorials for hours to no avail.I want a single function to produce the number from the selected artist and place it into a variable, then go through all of the loadImage(for the "album image") etc functions..they will be functions that I have made already previously and call all of them with the number in the called fuctions (ex: loadImage(0)) where "0" is the number derived from the variable out of the combo box.Ive tried tons of tutorials, I think that it has something to do with me using flash mx 2004, and as2 turned on.
I tried with some codes but I couldn't do the following in the popup1. I need to select items when I click I need change the filter effects or colors2. After selecting item in each category that filter effect won't go.
I have an issue with Spark Lists whereby I am trying to ensure that an item is always selected and ensure that the GUI displays this to the user.
The application (full code below) creates a List, a Label and a Button. The Label states what is selected in the List. The button removes the selected item. Changing the selection, updates the text in the Label. Important: The List has "requireSelection" set to true to ensure that an item is always selected.
If I select the first item in the List, the selection is correctly reflected in the label. Clicking "Remove" removes the item and the next item is selected. This is all working correctly.[code]...
so here is the problem that I have so far. I tried to simplify my code so I can attempt to figure this out, but I have had absolutely no luck. I have a viewstack that contains 1 dropdown per stack. They share the same data provider. What I want to do is to select the item contents from the first one. Once I do that, when I click a button to the next stack I have a function that searches from index 0 to the dataprovider length and if the item from the first stack matches the second one, I want to have the second dropdown pick that item up and display it. I have it matching, and I try to select it, but when I run the application it shows up like nothing is selected. Here is what I have:
edit: I got it to work for a simple example, but when I attempt to use it in my more complicated example, on that button click it for some reason resets the value of selectedIndex to -1. How do I prevent this from happening? This is working code for the simple example
In a spark list I could use the change event to find out which item has been selected or deselected. The dispatched IndexChangeEvent object has the properties newIndex and oldIndex holding this information.
But with multiple selection allowed this doesn't work anymore because newIndex and oldIndex could refer to indices of still selected elements.
A solution would be to copy the selectedIndices vector to another variable and compare this variable with selectedIndices after a change in selection, but this seems to be somewhat complex.
Does anyone know if there is an easy way two get the index/item a user is deselecting while other elements are still selected?
I have a spark datagrid on a mobile application, I set the
interactionMode="touch"
and the dataGrid scrolling is good, I got some problems adding a selectionChange eventListener to it, because scrolling the dataGrid will automatically change the selection and instead simply scrolling it, the function binded will start...
How can I add the touch dalay before select the index, so if I scroll the grid the selection won't change, and it change only if I press the item without scrolling?
Flash documentation says this is possible, but cb.selectedItem={label:'labeltext',data:'data'}; is a no go for me. Maybe I'm missing something obvious? Setting selectedIndex works great, but this should work too.
I have ComboBox With ArrayCollection as DataProvider. Data will come from Databse as ArrayCollection. I'm Adding Item to ArrayCollection "-Select Item-" at 0th index and setting selected index=0 for combobox.
When I select an item from the comboBox-list the selected item stays blank(visually) but the comboBox-list remains populated and change-event keeps firing.
This happens when I embed fonts and modifies or removes items from an existing combobox.
Here's the code that causes the anomoly: comboBox.textField.setStyle("textFormat", fontFormat); comboBox.textField.setStyle("embedFonts", true);
I have a combobox with arrayCollection dataprovider, it selects nothing at start, but i see the first object label as selected, i want to add select text, as first option that selects nothing, just to indicate that the user didn't select an option yet.
