View 1 RepliesI have a Tree Control inside my Flex Application which I want to edit on a doubleclick on a tree item. I found the properties doubleClickEnabled= "true", doubleClick="startEditMode()", and editable="true". With these functions I can detect a double click and I can change the editable property to true based on a double click. The problem is that after I double clicked on a Item i have to click once more to really enter the edit mode. That doesn't seem to be intuitive at all..

View 2 RepliesI'm loading a bunch of images through XML like this:
[Code]...
Pretty simple. Loads each image into a imgHolder_mc named 0, 1, 2, etc. Each image is also set to alpha = 0 since I don't want them to show unless the slider is changed.
[Code]...
any idea about the image gallery in the [url]... website? When you try to resize the browser it will automatically adjust its column..
View 1 RepliesI've reviewed all the documentation and Google results surrounding this and I think I have everything setup correctly. My problem is that the symbol is not appearing in my app. I have a MovieClip symbol that I've embedded to my Flex Component. I need to create a new Image control for each item from my dataProvider and assign this embedded symbol as the Image's source. I thought it was simple but apparently not.
Here's a stub of the code:
[Embed(source="../assets/assetLib.swf", symbol="StarMC")]
private var StarClass:Class;
protected function rebuildChildren():void {
iterator.seek( CursorBookmark.FIRST );
while ( !iterator.afterLast ) {
child = new Image();
var asset:MovieClipAsset = new StarClass() as MovieClipAsset;
(child as Image).source = asset;
}}
I know the child is being created because I can draw a shape and and that appears.

View 1 RepliesI'm try to lower the contrast of a movieClip, but it seems to have no effect. contrast, saturation, brightness do nothing.
My Code:
var bobRun:MovieClip = new bobRunning(); addChild(bobRun); bobRun.scaleX = .45; bobRun.scaleY = .45; bobRun.x = 350; bobRun.y = 30; bobRun.contrast = -100;bobRun.saturation = -100;bobRun.brightness = -100;
i've got 5 images. i want the following things to happen:
1. the placeholder movie clip automatically tweens to adjust to the image's dimensions.
2. the transition between each image is a la: [URL] -- front page when you enter
3. the images stay on the screen for approx. 5 seconds each.
I currently have a photo gallery where the images have a basic fade when switching photos.But I came across this site and their gallery, and noticed it's not just a simple fade... but looks like a high contrast fade, or something else. Does anyone know if this is able to be done with flash and actionscript 3.0? Or are there other components, programs, applications involved?
View 2 RepliesI have an Image nested inside a Canvas.
<mx:Canvas>
<mx:Image source="@Embed(source='assets/library.swf', symbol='Waves')" />
</mx:Canvas>
I'd like the Image not to overflow the bounds of Canvas. But when I set width and height on the Canvas, my Image disappears. Canvas also doesn't seem to respect horizontalScrollPolicy.
Seems easy enough, but as the official Flex documentation is down at the moment, I thought I'd turn to SO.

View 2 RepliesI 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 got some text that has a background, and the backgroud color can change to any color.
So, I need to find a way to figure if my text will be readable or not, the text should change to black (for example, yellow background) or white ( dark blue background ) if the contrast is not good enough.
So, is there a method to do this?, what would you use to make this work?

View 1 RepliesIn Flex 3, I've created a ComboBox within an MXML component similar to the following:
<mx:ComboBox id="comboBox" dataProvider="{_choices}" />
<mx:Script> <![CDATA[
import mx.collections.ArrayCollection;
// etc...
public function get choices():ArrayCollection { return _choices; }
[Code] .....
In the parent MXML application, I'm modifying the contents of the choices property:
myComponentId.choices.removeAll();
myComponentId.choices.addItem({data: "NY", label: "New York"});
myComponentId.choices.addItem({data: "CA", label: "California"});
// etc...
The binding is working in that the ComboBox is automatically picking up the new contents added at runtime, however it is not adjusting its width. The initial width of the ComboBox is wide enough only to show the initial item "All" declared in the component. However, I want and would have expected the ComboBox to re-size automatically during binding to be able to show "California", but it isn't. How can I get the ComboBox to update its width after I have added new wider labels to its dataProvider?
I'm building a small Flex UI component that displays a colored square next to a label of text. I want to be able to specify a size for the square and internally adjust the label's properties such that the line height matches the square and the text is vertically centered with respect to the square.
At the moment, I'm using mx.controls.Label for the text. Setting the fontSize style to the square's size does not work, the label then becomes too big. After tracing a couple of values in the debugger, I found that
the line height of the internal text field (sum of the ascent and descent properties of the TextFieldMetrics object obtained through getTextFieldMetircs()) seems to end up about 120% of what I specify a s font size.there's a default "leading" of 2 pixels that I can not change directly at the Label level, this adds to the overall height of the internal text field (getTextFieldMetrics().height)the height of the Label component then is an additional 5 pixels larger than that, I don't know where those come from.
I'm trying to create the following component: Just for information, the blank space will contain a text control, and I'm creating a component that represents the black corner with the (i) icon and the "promotion" text. The part I'm having issues with is this component representing the black corner with the diagonal text. The text has to be able to hold 2 lines. And the black corner has to be able to adjust to the text's size. What's more, the text has a rotation... I'm having some doubts on how to do this:
Should I have different controls for each text line? Should I draw the text in the shape (after doing the rotation) or should I just overlap both components? [When I talk about drawing the text in the shape, I mean in the same way as asked in this question] Is there any way to get the proper size of the triangle shape without doing some extravagant calculations?
