When i try to override the updateDisplayList to draw a backgroundImage for a tab navigator, the background does not fill till the end of the tab navigator. A space equal to the tab bar height does not get filled by the background. same is the case when I use an Image as backgroundImage. Any idea how to get this resolved?

Which is used this way:
<monitor:MonitorDisplay backgroundImage="{ log_img }"/>
The above will Embed the image into the swf,but I want the image to be loaded from the current website,like
<img src="/images/logo.jpg" />
How to do this?
I tried this but doesn't work:

I have a custom component that has an background image.ut when you generate this component by an ItemRenderer in a List, the background image is gone.hat am I doing wrong?Here is an image. The first element is not generated in a list and has a background image.he other three are part of a List and have no background image.Here is the code of the MXML of the List
<mx:VBox>
<solutionItems:displaySolutionItem /> <!-- This element shows the background image -->

In flex component life cycle, after we make some change in a components property, invalidation methods schedules a call to methods like commitProperties, updateDisplayList, etc for some later time. I need to call the updateDisplayList instantaneously. Is there some direct way to do this.
Currently, both the labels are changed simultaneously after completion of the loop. Instead I need it to work like this, to first render the updated 'myButton1' label then enter the loop and then update myButton2's label. I know, it is elastic race track issue, but isn't there some way to achieve this ?[code]...
Overview: The code giving me the problem is deployed here: [URL] The problem I am running into is that a certain sequence of actions (I don't fully understand how or why) is causing my calls to invalidateDisplayList to fail to produce a subsequent call to updateDisplayList. What I know is that during this period, some other visual effects will fail to occur (such as changing the width of a component or the addition of a new child).
Example: The program below draws two columns of horizontal lines. The column on the left is drawn during commitProperties, the column on the right is drawn during updateDisplayList. A certain sequence of actions can cause the right column to stop updating.
To trigger this bug: First add a new item. Now hit the start button and a bar starts filling up. If you press the add row button, the right column and the filling bar both stop growing. The left column continues unfettered. The extra component won't appear until the last line of the if statement in TEComputeRow.tick() doesn't execute for a frame. Click on the stop button to halt the execution of the block inside the if statement in TEComputeRow.tick() and everything goes back to normal.

I have a custom component which is an HBox & I'm trying to resize a child which happens to be an image. This is image is inside a VBox which is also a child of the HBox. I have a number of these images so In UpdateDisplayList I call:myimageArray[0-5].setActualSize(50,50);but the image is never resized it just stays a large default size. The images source is a url path and I'm wondering if that is what is causing the problem?
View 1 RepliesI have an item renderer for a grid that has a fairly basic updateDisplayList function:
override protected function updateDisplayList( w : Number, h : Number ) : void
{
super.updateDisplayList( w, h );
var labelWidth : Number = Math.min( _labelDisplay.measuredWidth, w );
[Code]....
The next time I scroll the renders update to look like they should - but updateDisplayList is NOT called here (on the renderes). All that happens is that the renderers are re-positioned in the grid. Both the background and the label are displayed incorrectly initially so it's not just the label mis-behaving.
I've created a custom MenuBar to make this happen. But it just doesn't seem to happen. It never renders any of the changes I made to the Graphics.What am I doing wrong?[code]
View 1 RepliesSo updateDisplayList is for laying out, positioning and sizing a component's children. It seems a waste to me, however, to have all that code running every time a render is called, even if no changes have been made to the relevant properties or child properties.The way I get around this for performance's sake (working on mobile) is to set a flag inside of my overridden updateDisplayList that lets a big part of my own sizing/positioning code run only the first time.Is this a bad idea/ big mistake? I just can't see the benefit to letting it run every time otherwise if I don't expect anything that affects sizing/positioning to change.

Is there some way to have a tab navigator in flex where each tab width can be controlled explicitly ?
View 1 RepliesUsing CSS, I can set the corner radius of the top corners of a tab in a tabnavigator:
<mx:Style>
.tabstyle {
corner-radius: 10;
} </mx:Style>
<mx:TabNavigator tabStyleName="tabstyle" />
However, I also want the bottom corners to have a radius.
I have a component mxml in which i have a save button, on click of the save button i need to display another component which will be in a tab navigator, for this I am using the view stack. My problem is, on click of save I need to display the second tab instead of the first tab, but defaultly the first tab will be displayed.
View 1 RepliesI'm trying to create a custom tab navigator that has to look like. Also, when there's a rollover, the borders of the arrow have to be in blue (like the label in the current tab). For that purpose, I've created a custom component: a hbox containing a label and a canvas with 3 images inside (for the arrow tip that has to change depending on the currentState). Then, I thought of overlapping the components in order to get the blue highlight color (ex: arrow button 3 is over arrow button 4. The image of the arrow tip in button 3 will be transparent outside the arrow, so that we can see the black color of the following button).
I'm now trying to position the components inside the canvas ... but I cannot. After the creationComplete event, I assign the label text and I was calculating the coordonates of the component but it doesn't take into account the label width... -_-'

Suppose I have two tabs in my app:
<ViewNavigator id="tab1" firstView="Tab1">
<ViewNavigator id="tab2" firstView="Tab2">
I go into Tab1, and start pushing other views onto the stack
navigator.pushView(Tab1View1)
navigator.pushView(Tab1View2)
and so on....
Now I want to jump directly, with NO TRANSITIONS, from one of the views deep in Tab1, into one of the views in Tab2. How do I do this?
My problem: I have a tab navigator, with many forms in each tab. But I have a single global save button.Problem is, if I don't open a Tab, it doesn't get initialized and therefore the forms it contains do not exist..
How Can I make it as if the user had clicked on every tab?
This is a general question on optimization technique and am more than willing to rewrite a majority of my code as I am moving a lot of it to a library.My concern applies not so much to flex performance as I have used methods that have reduced cpu/memory footprint so performance is quick when inside a view.The problem I have is with the navigator.pushView which seems slow, I do call my init function on creationComplete for the view but I have it factored so my init looks like:
private function init() : void {
doStuff1();
doStuff2();

how to create a specific navigator effect. I'm sure you've all seen it. I'm just having some trouble with the scripting. What I want to happen is I have a map and you can only see a small section of it, when you click on a button the map slides behind the window to the new point. I've mainly seen this done in photogalleries where all the images are layed out on a grid inside a MC behind a mask then the MC slides around to show the selected image.
View 1 RepliesI I have a view in Flex 3 where I use a tab navigator and a number of views inside the tab navigator. I need to be know which view was clicked because of it's one specific view then I need to take action, i.e. if view with id "secondTab" is clicked then do something.
I have set it up to be notified, my problem is that I need to be able to know what view it is. Calling tab.GetChildByName or a similar method seems to only get me back a TabSkin object.

I am looking for some creative examples for interactive methods to navigate a tree hierarchy. Conceptional ideas or some good Flash/ Silverlight/ HTML 5.0/OpenGL examples of such navigation would be great. I'm not concerned with the technology at this stage.My problem that is that I need to deliver information to a user in the form of a questionnaire hierarchy. Consider each node in a tree hierarchy as a question where each question answered takes the user to the next level down in the hierarchy of the tree were there are a further number of question(s) to be answered. At the very last node, there will be the final solution. I have found this useful(url...). I would like an interactive version of this with each node been expanded to show further nodes etc.

View 1 RepliesI have a flex application mxml file with 3 tabs.the first tab having the link button to select the value in the 3rd tab. Suppose, i have a link button in first atab. And the 3rd tab contains the combobox with values:"basic", "advanced". by default the vaule is displaying "default". When i select the linkbutton on the first tab, the "advanced"should be displayed in the comboBox on the 3rd tab. and the problem is , when click on the first tab link button , at that time the 3rd tab is not initialized. So it is not displaying the "advanced" in the comboBox. selecting the 2nd time on the link button it is displaying fine. But not first time. code: thirdTab.comboBoxId.selectedItem.data = 1;
