I have a canvas component that I create and add as a child of a parent canvas component. I set the opaqueBackground property for the child component which makes it opaque over the parent component. However, when I add two child components, they are not opaque over each other. How do I set it up so that one child component completely covers up the other child component?

I want to dynamically add different items to thumbContent canvas and use scroller canvas to scroll. I see than the height of thumbContent bigger than 7977 it truncate from scrolling. So - I see the scroller canvas with empty space on top. Then I scroll to bottom - I see the content of thumbContent and at bottom scrolling I see empty space too.
I'm trying to skin a canvas with an image (which is essentially a custom border for the canvas). I've been trying the backgroundImage style as well as the borderSkin style. I can't get the image to scale to the full size of the canvas though. I was wondering what the best way to go about this is.[code]...
View 2 RepliesI 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?
I made a program in Flex that uses the actionscript 3 drawing api. I am drawing on a Canvas and on every mouseUp event I save the bitmapData in an Image component and clear the the Canvas. That works great, but the problem appears if I want to add a background to the paint that was drawn.
Here are the mxml components:
Code:
<mx:Canvas id="_backgroundColor" width="100%" height="100%" x="0" y="0" />
<mx:Image id="_image" x="0" y="0" mouseEnabled="false" />
<mx:Canvas id="_paper" x="0" y="0" />
And here it is the function I have on the Canvas (_paper) mouseUp
Code:
private function onSaveModifications(evt:PaperEvents):void{
var bmpData:BitmapData = new BitmapData(this._paper.width,this._paper.height,true,0x00FFFFFF);
bmpData.draw(this._paper);
this._image.source = new Bitmap(bmpData);
this._paper.graphics.clear()
}
I want when I set the _background Canvas background color to see it, but I cannot because the Image component(_image) where I save the bitmap is masking it.
This is how I set the background
Code:
this._background.setStyle("backgroundColor",0xff0000)
Do you know how can I make the pixels of the bitmap that weren't drawn to be transparent?

View 1 RepliesWe are currently thinking on getting our apps automaticaly built and tested through a CI server.My major concern is regarding UI tests.. I've been playing with FlexMonkium/Selenium IDE in Firefox but it doesn't really play nice with my app. I'm also testing RIATest 3 but I would have liked the Firefox approach better because it's easy to use for non technical users..A bigger concern is that my app is really complex, using custom events, custom components, ExternalInterface calls.. in order to make it all work smoothly, should I give an automationName to every single component ? How can I handle custom events ? RPC responses time
View 1 RepliesI've two problems, the second of which is only an issue because it's a possible way to fix the first! I'm developing a Flex 4.1 application, using a Spark theme: I can't change these; Halo isn't an option. It's providing the facility to fill multiple-selected cells of an AdvancedDataGrid with a single character, from a single keypress. So the user selects their cells using the Shift key, hits H (for example) and sees all the cells update with H, without using an itemEditor but via grid keyDown events instead. Then they click somewhere else and the selection should clear.
However the visible selection isn't fully cleared and the newly coloured cells won't all change from their selected colour. Underneath I can verify that the selection has cleared: mygrid.selectedCells is empty. All behaviour afterwards points to some kind of display glitch with the grid: The cells aren't selected any more but they look like they are.

I have a component "child" which has a cancel button. Now this component is placed in a state called "newChildComp" I also have another component called "parent". In the parent component, i have a button that dispatches an event. Here is the event code:
[Code].....
so, basically,i am checking to see if the cancel button component in the Child component, while i am still in the parent Compoent, was clicked, if it was clicked, call the cancelButtonHandler. The problem is by the time the addNewChild handles the event, that cancel button was still null. My question is how do i solve this without using the itemCreationPolicy on the cancel button?
Flex charts, like AreaChart, have wonderful built-in support for displaying data "tool tips" when a user hovers over a point supplied in the data of a graph. You can hover over any of the bar graph examples on this page for a demonstration. I have a graph situation where I optionally draw in some dots as reference points on CartesianDataCanvases supplied to my AreaChart through it's <mx:annotationElements> and <mx:backgroundElements> tags.
I would like to have the same hover data-tip functionality that the AreaChart has, but applied to these dots. I realize that I am just drawing on canvas, and that no actual dataProvider supports these dots, but if there was a way to supply the CartesianDataCanvas with an array of data values or something to that effect,

My code above works absolutely fine, until i resize my browser window to a size below 800px width. When the browser window is make of lesser width than 800px, the canvas with background color #A8A8A8 is on the right of the window, but the problem is, when I move the scroll bar, the canvas should remain on the right of the window. Which does not happen, and that is what my problem is.
How can I solve this issue. What should I do to keep my canvas be on the right=0 all the time.

Basically I want to go to frame2 when the cursor leaves the canvas. The code below contains no errors when tested but it still does not work.
[Code]...
We know that the function gotoAndStop(frame2); works in multiple situations which means the first 3 line is fine. I don't know if the problem is the MOUSE_LEAVE event or this.stage which i suppose is the identifier for the canvas. I sure that there must be an alternative code for the identifier this.stage or the whole code. Any solution on how to fire the given function in the event when the cursor leaves the canvas?

In flex, I am using

But I am not able to put border on the sides of canvas.
I'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... -_-'
The problem is when background of top or below label is changed, the top or below button is erased.

I'm trying to draw a String inside a canvas. The text and the position of the String changes pressing differents bottoms. For doing so, I create TextFields which I added to a sprite which I added to a Canvas:
canvas.rawChildren.addChild(spriteNombres);
The first time everything works fine but when I press the bottoms,it does not refresh and appear the old textfields and the new ones.I cant remove the old ones, I try with removeAllChildren and also trying to delete one by one with removeChildrenAt. I do not know if I'm doing something wrong or maybe this is not the best way.
I also try creating bitmapdata and drawing in the sprite inside a rectangle.

I'm doing an application in flex where I draw different sprites inside a canvas. Depending of the dimensions, scrollbars can be appear.

In this way, you dont have to touch the scrollbar.I'm start trying with drag and drop properties of the canvas, setting the position of the scrollbar according with the movement of the mouse but that is not as I expect.
