I'm stumbling my way through designing my first Flex app, using Flex Builder 4 Beta 2. I'm trying to use a ComboBox, but they always seem to have lines around it and I can't figure out how to get rid of them. The ComboBox looks like this: [URL] All I did was drag the ComboBox from the Controls section in the Design section of the UI onto the screen. I haven't changed any settings, no special css, just used the default ComboBox and this is what I get.
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.
I have been working on a map viewer based blitting technique. As part of the map I need to draw approximately 50000 lines and performance is currently really poor.
My code is on the main timeline.I call a function loop to draw lines between them.The lines are drawing between the right x, y values BUT between those values on the main stage, not those values within the kite.For example, dot1_mc is at x100, y0 inside kite. the line that should go from its center, draws from stage x100, 0.How do I draw the lines inside kite so that they draw between the dots?Heres my code that draws the linesPHP Code:
function loop():void{ lineDrawing.graphics.clear(); var a:Point = new Point(kite_mc.dot1_mc.x, kite_mc.dot1_mc.y); var b:Point = new Point(kite_mc.dot2_mc.x, kite_mc.dot2_mc.y); var c:Point = new
In my Flex 4.5 mobile app, I have an actionScript item renderer (that derives from Flex's LabelItemRenderer). I want to fit in exactly 2 lines of text, and then truncate the rest. The width and height of the label are fixed and known statically. How can I do this? The StyleableTextField.truncateToFit() method only works for one line of text.
I've set wordWrap = true, so the text now flows into the second line - but I need to truncate the text if it doesn't fit in two lines. I need it to show all the text if there is only one line. (in both cases the label should be vertically middle-aligned in my renderer) I know how to override layoutContents to do sizing and positioning etc of the StyleableTextField. So I'm looking specifically for ideas to implement custom text truncation with the StyleableTextField).
I'm trying to setup a DataGrid that contains a column of combo boxes. The values of the combo boxes are defined by data specific to that row. I cannot get this to work though, I'm asking for a solution to this, either fixing what I have below or a recommendation on a different way.One of the columns of my DataGrid has an object derived from a ComboBox for an ItemEditor. The itemEditor is set like this:
I want the comboBox to be placed in one of the columns of the datagrid header.The datagrid should be filtered according to the value selected in the comboBox.e.
I'm trying to draw lines on a canvas object. When the width of the Canvas is less that the width of the line, it draws outside the Canvas over other elements. I read about this problem and I try to resolve using a inner Canvas with a longer height so a scrollbar appears.But I also read that this problem can be correct using a mask but I do not know what is the better way. Which do you recommend?
I have one left panel in which there are different shapes like start,end connectors..... when i drag line image inside canvas i want to draw line/connector between two shapes how would i do it
I created a TextArea object. Then I typed some text in it. Then i got this text useing TextArea.text property.How can I split text I got by lines and convert it to the array of strings?
I'm using Flash CS3 and want to create a custom ComboBox. I've followed the steps outlined in "Editing component skins in a new document" (http:/[url]...), but every time I get to the step where I drag the ComboBox Assets folder from the HaloTheme.fla library into my library, if I test movie at that point my combobox has become an unclickable white rectangle with no label, button or anything.

Both of my ComboBoxes has the same identifier.I could not change the identifier through the properties tab because it is greyed out.
I use FDT for my flex programming and there are some warnings that I want to suppress.for example:Private function is never used. Found 'list_ itemRendererFunc' at line foo column bar.I actually paste this function name as a string to a datagroup's itemRendererFunction property. how do I mark this line that will not show the warning?
Flex has a plotchart component and a linechart component.. but I am looking to make a chart that has lines connecting points as well as larger dots with rollover info. Is this easily possible? Would I have to create a custom component from scratch to achieve this?
it's a little ridiculous; and probably unbelievable, but when I have more than five hundred lines of actionscript in tags in my MXML FLEX Main.mxml, all syntax highlighting, error and syntax verification, error reporting, "Problems" pane, and even sometimes compilation fail. Upon removing any chunk of code, it works again.I don't see why Adobe could release a product such as Flash Builder 4.5 Premium, have this big of a problem; and nobody notice. Therefore I believe the problem has to do with my computer, or my project; as there's now ay more people have had this happen if I can't even find it on Google.
Additionally, many objects that have been defined in the MXML properties above the code, even those in All States, are now showing as warning: Access of undefined property down the side of my document. However, these warnings are not showing up in the "Problems pane", and aren't even yellow squigly underlining the right sections of code to pertain to the message.Steps I have taken to TRY and fix this:I have tried restarting, as well as re-installing the IDE (Adobe Flash Builder 4.5).I have tried creating a new projectI have tried splitting my code into smaller .as files and including them.I have tried compiling my application.
I am using a spark list control to display certain items with my custom Item Renderer. I am trying to achieve the following: (1) show a separating line between rows in my list control (2) even when not a single row has been added, I want a horizontal grid lines to be displayed in the background
I am not sure whether (1) and (2) can be achieved in one go. I can solve (1) by modifying my item renderer to have a border, I guess. But I want to know whether there is a better or more conventional way.
I've made an animation showing the constellation Orion in 3D (see attached swf). As you can see, it's working properly, displaying stars and lines connecting those stars. The depth scaling is ok. The animation also responds to mouse movements as it should.The problems occur when I embed the swf in Flex using Flex Builder (I posted this question on the Flex forum as well, but I suspect the problem is more AS related than Flex 3 related): the stars of the constellation are visible, the animation responds to mouse movements, depth scaling is OK...but the lines connecting the stars aren't visible. Feel free to make the comparison for yourself.So any suggestions how I can make the lines visible? Can they be exported for Actionscript in the same way the movieclips are?Geography and sciences teacher (not a professional programmer alas)I used Flash CS4 professional version 10.0.2 , Flex Builder 3, IE8, Flash Player 10

I have a flex app which allows user to create some content. this content will then be sent via xml back to the server:
private function saveBackXMLToServer():void { var params:Object = {}; params["xml_file"] = XML_content(); http_Service.send(params); }
My problem is, that the transport of the data this way is very slow... It takes about 20 sec for 10'000 lines of XML... How can this be done better?
I'm trying to follow all of your hints, but they don't seem to be simple to change. My code is done in a way that I can't get access to every Object, and save it. So what I do is to load the swf file with one xml, and return the whole xml after I run it. My guess is, that the time isn't spent on transporting those lines to the web server (this task gets done quickly normally), I thing that there happens something on the send function of the HTTPService that every object must get changed, before sending...
UPDATE2: I just realized that it is not a matter of the flex app it is a matter of the rails app. It receives a 700 KB String. I guess it is not done for handling such a object. How to transport it then? I tryed to work with the file upload but couldn't get it done... Error 2037 was occuring! I'll go on trying.
I have a datagrid column as follows: <mx:DataGridColumn headerText="Description" dataField="description" editable="true" editorXOffset="2" editorYOffset="2" editorHeightOffset="20" editorWidthOffset="60" itemEditor="com.jono.controls.DgItemEditor" wordWrap="true" />
And a very simple DgItemEditor: <?xml version="1.0" encoding="utf-8"?> <mx:TextArea xmlns:mx="[URL]" wordWrap="true" backgroundColor="#FFFFFF" backgroundAlpha="1"> </mx:TextArea>
Basically, this allows for a small 'popup' when the user edits a cell in the datagrid, allowing for more space to type. The problem that I am having is that the datagrid gridlines show through the itemeditor - i.e. the itemeditor is transparent. Is there any way that I can force it to be opaque?
If you are using Flex 3.5 (not my choice) and you scroll the mousewheel over a Text component with multiple lines of htmlText, it will scroll down 1 (sometimes 2) lines, even [URL] I made sure there is not a blank line below the body of text (it ended after the closing). Notice how the top line is now cut off, and an extra line was added at the bottom.
I have a Line chart with 12 Legends. Hence the are getting truncated at the end instead of wrapping around dude to lack of space. show the remaining legends on next line. e.g 6 legends on each ln
I have a candleStickChart in flex 4.5 with a dateTimeAxis horizontal axis.I wish to have a button that enables to draw a line on top of that chart.I wrote a code that each time the button is click, a new CartesianDataCanvas is created. than I do a pretty standard line drawing by listening for the MOUSE_DOWN, MOUSE_MOVE, and MOUSE_UP to draw the line.In the MOUSE_DOWN event I create the new CartesianDataCanvas, and update the annotaionArray as described in the following code: (candles is the candleStickChart's id)
public function startDrawing(event:MouseEvent):void { canvas = new CartesianDataCanvas;
I have an app that has text appended to a TextArea (TA). It automatically scrolls to keep the recent line added in view. Over time, this could be a lot. Do I have to worry about this? Is there an upper limit? And, if so, how can I prune the oldest lines of text?
