I'm gonna try explaining my situation with images, to make sure that everyone will understand what i want to succeed.
First of all i have 3 files:
GenImage.fla which is linked to class GeneralImage.as and it only contains the following picture (I tried to make the image Movie Clip but again it's not working):
and a file named ScrollUI.as which contains the class ScrollUI.
What i want to succeed is from my GeneralImage class to create a ScrollUi item, pass the stage, and there create a ScrollPane which makes the picture look like this:
The center part of the second image is the ScrollPane Component, which i need to make it Scrollable through the whole image. I managed to get it in my screen but i can't put the Stage in it and make it scrollable.
These are my codes :
GeneralImage.as
package {
import flash.display.*;
import flash.events.*;
import flash.display.Stage;
import ScrollUI;
public class GeneralImage extends MovieClip
{
public function GeneralImage()
{
var k = new ScrollUI();
k.ScrollConstructor(this);
}
}
}
ScrollUI.as
package
{
import flash.display.*;
import flash.events.*;
import fl.containers.ScrollPane;
import fl.events.ScrollEvent;
import fl.controls.ScrollPolicy;
public class ScrollUI extends MovieClip
{
private var _mainStage:Stage;
var aBox:MovieClip = new MovieClip();
var aSp:ScrollPane = new ScrollPane();
public function ScrollUI()
{
}
function ScrollConstructor(stage:Object):void
{
_mainStage = (stage as MovieClip).stage;
aBox == stage as MovieClip;
aSp.source == aBox ;
_mainStage.addChild(aBox);
aSp.setSize(300,300);
aSp.move(150, 75);
aSp.scrollDrag = true;
aSp.horizontalScrollPolicy=ScrollPolicy.OFF;
_mainStage.addChild(aSp);
}
}
}
So what i want it to set the Source of the Scroll Pane ( which is named aSp ) to be the _mainStage which is the stage i get from GeneralImage
Your issues is likely these two lines:
aBox == stage as MovieClip;
aSp.source == aBox ;
You're doing a comparison by using two ==, which effectively does nothing in your case. Use a single = to assign a value.
This is how I would suggest you approach this:
In the FlashPro library, find your image asset (I'm going to assume you have it wrapped in a MovieClip), right-click (or command click) and go to it's properties. Check the "export for actionscript" box, and give it a meaningful class name (for my example, I'll assume you called it MyImage)
Then you could do the following:
ScrollUI Class
package
{
import flash.display.Sprite;
import fl.containers.ScrollPane;
import fl.events.ScrollEvent;
import fl.controls.ScrollPolicy;
public class ScrollUI extends Sprite
{
//just declare the variables here, don't assign them new values
private var aBox:MovieClip;
private var aSp:ScrollPane;
public function ScrollUI()
{
//use the actual constructor...
aSp = new ScrollPane(); //instantiate a new scroll pane
addChild(aSp); //add the scroll pane to the display
aBox = new MyImage(); //instantiate an new MyImage from the library
//set the scroll pane properties
aSp.source = aBox; //you had two = signs here before, which doesn't actually assign anything it compares
aSp.setSize(300,300);
aSp.move(150, 75);
aSp.scrollDrag = true;
aSp.horizontalScrollPolicy=ScrollPolicy.OFF;
}
}
}
Document Class
package {
import ScrollUI;
public class GeneralImage extends MovieClip
{
public function GeneralImage()
{
var k:ScrollUI = new ScrollUI(); //create a new instance of the ScrollUI class
addChild(k); //add the scrollUI object to the display;
//OR, you just do this:
//addChild(new ScrollUI());
}
}
}
You could also just set the .source property of the scroll pane to the physical path of your image.
