Re: [flexcoders] Question about drawing on the canvas

2005-10-05 Thread Prasad Dhananjaya 
Hi Manish  all,

 The solution is to make it a child (add a new object as a child and
 draw on top of that object instead).

sorry... , I didn't get the point yet.Is it Mean..

addedObject = Object(myCanves.createChild());
addedObject.createChild(arrow(target));

or

var ref_mc =myCanves.createChild(mx.containers.Canvas,undefined,{width:1000});
ref_mc.createChild(arrow(target));


Please explain me little more.

Thanks

 It indeed is on the Canvas, but it's not a child of the Canvas, and
 that's the reason it doesn't scroll along with other children.

[flexcoders] Questing about Automatic Scrolling

2005-10-03 Thread Prasad Dhananjaya 
Hi,

Have a problem with automatic Scrolling.

Can someone help me..

There are 2 canvas in my test application.
Size of the JobNetCanves is 10 times than fullMapCanves. On the 
fullMapCanves there is a image(call selector) which is dragable 
inside the canvas.
 
What I want to do is ..

when I move selector, scrollbar of JobNetCanves also want to move 
automatically.(When moving selector inside the fullMapCanves,left 
top cordinates of the JobNetCanves is same as  selector.x*10,
selector.y*10)

Can someone tell me how to do this..

thanks.

P.S.
I think I can do this with using vPosition  hPosition . But not clear how 
to get/set values.

[flexcoders] Question about destroyChild()

2005-10-03 Thread Prasad Dhananjaya 
Hi all,

Is it possible to destroy child by specifying x,y coordinates.

I used createChild() to draw square.

--code-start--
var xvalue:Number=100;
var yvalue:Number=100;

 var ref_mc1 = 
myCanves.createChild(mx.containers.Canvas,undefined,{percentWidth:100, 
percentHeight:100});   
ref_mc1.fillRect(xvalue, yvalue, xvalue+8, yvalue+8, 0x00, 100);
-code-end-


Now I want to delete it by specifying  xvalue, yvalue. How can I 
specify x,y coordinates to getChildIndex(). Is it possible?


--code-start--
var xvalue:Number=100;
var yvalue:Number=100; 

var iChildIndex:Number = myCanves.getChildIndex(event.target);
myCanves.destroyChildAt(iChildIndex);

-code-end-


Thanks,

createChild().

1.How can I give mouseOver,mouseOverEffect,mouseOut,mouseOutEffect,mouseUp
events to createChild().(check ★).I want to give above affects to all 
created children which are on the JobNetCanves. 
(In below code all  mouseOver,mouseOverEffect,mouseOut,mouseOutEffect,mouseUp 
functions are working well)

2.Want to delete child at double click. What words I have to write in 
destroyChildAt(JobNetCanves.getChildAt(★★));

Please help..

[flexcoders] setting effects to createChild()

2005-09-27 Thread Prasad Dhananjaya 
Hi All,

Can someone tell me how to set 
effects(mouseOver,mouseOverEffect,mouseOut,mouseOutEffect,mouseUpevents) to 
createChild().Below line is not working(and giving no compile errors). Checked 
several docs. But found nothing helpful.

var img=target.createChild(mx.controls.Image,, 
  {source:img23, x:9, y:2,
  mouseOverEffect:myZoom,
  mouseOver:popToTop(event.target), 
  mouseOverEffect:myZoom,
  mouseOut:restore(event.target),  
  mouseOutEffect:cut, 
  mouseUp:doubleClickDestroyChild(event)});


P.S.
What I want to do is to set effects to all createChild components
which are on the canvas.Is there any way to do this easily.

Thanks,
Prasad

Re: [flexcoders] Question about mouseMove

Hi,

Thanks for your reply.

Now it's working. But still have a problem. I can't use clear(), 
because it deletes all previously drawn arrows.
Any other way to do this with out deleting other arrows which are 
on the canvas?

Thanks,

 You need to call your draw function via mouseMove, but have the drawing algo 
 clear() each time.  Additionally, add an updateAfterEvent() at the end of 
 your function since mouseMoves can happen faster than the screen can redraw. 
 The mouseUp function will then call the same function, only once.

 I am not sure how to implement this or how this would affect your
 performance, but you probably need to use a doLater() to let the screen
 update.

 Hi,
 
 I have a small question about mouseMove action.
 
 Below code draws an arrow between mouseDown point and mouseUp point.
 It works well. But arrow displays only after mouseUp event.I want to
 display arrow during moving of mouse (before I do mouseUp).
 I think I have to add something to mouseMoveHandler().
 But didn't know what? Can someone tell me how can I do this?
 
 Thanks,

[flexcoders] Question about moving of dragged image

2005-09-14 Thread Prasad Dhananjaya 

Hi all,

I have a problem with moving of dragged image. Can someone help me to
solve this.

There is a image(job1.jpg) in the canvas cvs. DragDrop of job1.jpg to 
canvas(JobNetCanves) is working well. After drop it to JobNetCanves, it 
can't move again. I want to redrag it and drop freely inside the
JobNetCanves canvas.(In other words want to re-locate job1.jpg anyway 
in the JobNetCanves).

moving an image inside the JobNetCanves is OK. Image of job13.jpg can 
re-locate freely inside the JobNetCanves(It is not a dragged image from
cvs)

I think, If I can use job13's  dragMe() and myoffset() functions to 
job1, job1.jpg,it may move freely inside the JobNetCanves after dragging
it from canvas cvs.

How can I specify dragMe() and myoffset() as property of createChild()?
Or is there any other way to do this.


Thanks

[flexcoders] Question about moving image

2005-09-04 Thread Prasad Dhananjaya 
Hi all,

I am making some test programs with the help of tutorials and Flex 
samples. But have a problem with implementing below function.
I am very glad if someone can give me a advise, sample code or
url of document which I can refer.

what I want to make is:

1.In the application there is a canvas and GridItem(images).
2.When I click(mouse button is pressed down and released) on the
  image and then move the mouse pointer to the canvas, clicked 
  image will appear on the canvas with mouse pointer.
  (When I move mouse pointer inside the canvas image also moves with 
  mousepointer)
3.when I click(mouse button is pressed down and released) on the 
  canvas then image drops on the canvas(at the clicked place). 

Thanks
Prasad

[flexcoders] About Context menu

2005-08-23 Thread Prasad Dhananjaya 
Hi,

I want to display context menu only inside the canves area. 
But this code displays context menu in the whole application.
I think the problum is this[menu] part. Which
means the whole application. But I don't know how to specify
canves area.Is it possible to display only in the canvas area?

Thanks,
Prasad
