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]...

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,
I'm using the drawing API features to do the following: I created two different squares and want to use them as two different canvas to draw on, they should be on top of each other so for testing purpose I overlap them partially here, but somehow I'm having trouble when trying to draw on the overlapped areas. Has any one encountered this problem or know how to solve it?

View 1 RepliesI need to to incorporate a functionality where the user can use his mouse to draw a rectangle by dragging his mouse over the canvas - much like the Rectangle Drawing Tool in the Flash Authoring environment. The requirement is something like a rubberband tool where the user can define a portion of a map by drawing a rectangle over it. The coordinates needs to be captured.

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.

In flex, I am using

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.

View 1 RepliesI'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'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. I would like to move the "image" with the movement of the mouse as you can see at the Adobe Reader when you are reading a document with zoom (hand mouse icon). 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.
