Show component from main application mxml.

Hi all,
     I have a main application mxml and inside has a button named show_form. After that, I design an form named Form_A. And now, I want when click on show_form button fire the Form_A and made it appear.
     Hown can I do this ?
     Thanks !

There are many ways of doings this, it depends how your forms are shown.
Are they in a ViewStack or similar container? If so just change the view from the click handler function for the button.
If they are in a Canvas/HBox/VBox, in the click handler function of the button you can do a check like if Form_A.visible==true then submit it and hide it, else submit the other form. You can also have a variable that tracks if Form_A was submitted.
If you have code, post it here and we can find the best solution with a clear example in front.

Calling a method in a component from main application

Hi,
I have a mxml component( menu1.mxml) . In the menu1.mxml
there is a include for the actionscript file(menu1.as). In the main
application page(SampleLogin.mxml) I want to call the method in the
btnSubmit_Click() on the saveIndex() method for case 0. I am
attaching all the code below

case 0:
menuOne.btnSubmit_Click( );
break;
Also it would probably be following best practices to used a
custom event to pass the information in your "LoginButton_Click()"
function to the application.

Load/Unload Component from Main Application

I want to load in my main application 2 components. At this moment I load them with this:
<components:loadProject id="loadPrj" visible="false" click="loadPrj_clickHandler(event)" verticalCenter="7" horizontalCenter="0"/>
and I only set visible to true. Inside this component there is a canvas.
But, is there any other way to do this using an AS class file? I would like to load/unload it on click, not only set true/false to visible.

For dynamic creation and destruction of objects, you want to use ActionScript.
So in your main app file, you might have a button that triggers a click handler that does this:
private function myClickHandler()void {
                var b1:CustomComponent = new CustomComponent();
                var b2:CustomComponent = new CustomComponent();
                /// Be sure to add them to the display list if they are visual components
                myPanel.addElement(b1);
                myPanel.addElement(b1);

Run function in component from Main Application

Hello all.
I have my main.mxml application, that has a component inside of it. The component is called <ns1:record/> with an id of "rec".
This component has a function inside of it named doConnect(event:MouseEvent).
Now i want to be able to add an event listener to a button on the Main.mxml that will run a function inside the component when clicked.
I have managed to add an event listener to the Main.mxml that triggers a function held within the Main.mxml when a button clicked inside the component is clicked.
I did this by using this code.
            <ns1:record id="rec" x="9" y="6" camera="{camera}" microphone="{microphone}" creationComplete="makeEvent()">
            </ns1:record>             //Event listener
            public function makeEvent():void {
                rec.backbtn.addEventListener(MouseEvent.CLICK,swapstate);
            protected function swapstate(event:MouseEvent):void {
                viewstack1.selectedChild=config;
No matter what i try thou i cant get this to work the other way around.
What i need help with is - clicking a button within the Main.mxml to run a function inside the component Record.
If anyone can help that would be great !
Thanks in advance.

Hi djh88ukwb,
From your post if I understand you correctly you want to listen for a event in record component when a button in main mxml is clicked...based on this
assumption I am suggesting you a solution...
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" creationComplete="onCreationComplete()">
<mx:Script>
<![CDATA[
   private function onButtonClicked(event:MouseEvent):void
   rec.swapstate(event);
]]>
</mx:Script>
<ns1:record id="rec" x="9" y="6" camera="{camera}" microphone="{microphone}" creationComplete="makeEvent()"></ns1:record>
<mx:Button id="myBtn" label="Call Function in Record Comp" click="onButtonClicked()" />
</mx:Application>

public function swapstate(event:MouseEvent):void {
                viewstack1.selectedChild=config;
Please try this and let me know....
Thanks,

Events from main application to components

Could someone please tell me if it's possible to broadcast an
event from the main application to components that have been
declared inside the main application?

For the number of rows in the DataGrid just look at the length of the dataProvider.
For passing data between popups and app, the gold standard is to use custom events, and add the event listener to systemManager.
Here are some tutorials on custom events I created:

Show Dynpro from external application

I was wondering which possibilities exist to show a Dynpro page of an SAP application within another 3rd party application (written in Smalltalk).
As far as I know it is not possible to call an RFC which returns a Dynpro page, so which alternatives exist.
What came into my mind is the following:
- Using ITS and calling the respective URL from the external application to show the Dynpro in SAP GUI for HTML
- Re-Write Dynpro application in WebDynpro
- Re-Write Dynpro application in BSP
- Call BAPI/RFC to get application data on backend side and create an new UI to show the data in the 3rd party application
- Separate Logon to SAP systems
Do you see any other alternatives?
In my opinion the ITS solution is the only feasible way on a short term basis.
Any comments are welcome.
Thanks,
Michael

Looks like you've arrived at a pretty comprehensive list - depending on which version of SAP you are using, there's also the Web Service option to get data from SAP... or if you are very brave and the data is stored in a simple format (e.g. not BSEG!) then you could visit the database directly. You've got the usual dilemma regarding which of the 2 front tiers need to be implemented where - the SAPGui for HTML means you can leave everything to SAP which has its advantages e.g. consistent business logic...( you could also use ITS over custom dynpros built in ABAP - but that's probably heading away from the market trend )... the next two options require a re-rendering of the presentation layer - the advantage of BSP would be the richness of the result, the advantage of the WebDynpro would be the potential for having the output rendered in other SAP-supported GUIs in the future e.g. Flex. There may also be options around Citrix too - SAP training course here are presented this way via a browser-based solution.

Change States in component from main view

The scenario like this:
The main view includes many component views. On my main view
there have a radio button to choice different role type, for
example: admin and user. For different role have different views.
But they don’t have big difference.
My question is how could I implement my component view change
states when I click button on the main view? I don’t want do
change states in main view since I need create two component views
for different roles.
Thanks.

Consider adding a second state to your application, even if
you don't put anything into it.
In each of the components that should change state when the
role is changed, add a listener on the application for the state
change event ("currentStateChange"). When this event is fired,
query the application for its current state:
var appState:String = (Application.application as
Application).currentState;
Use that to change the state of the component. Remember
you'll also need to do this when your component is first
created.

Constructing a class extending JDialog when invoked from main application

In an application that extends JFrame a method, showJDialogGUI, is called to instantiate an object of another class (called enterGUI) that extends JDialog. This object, enterGUIDialog, is modal; user must click on its Submit button in order to dismiss it and be able to continue in MainProgram. I have troubles getting error messages resolved when the constructor of the enterGUIDialog JDialog object is called. Perhaps there are other things wrong with below code. Any help appreciated - snippet of code from both classes is below.
public class MainProgram extends JFrame {
enterGUI enterGUIDialog; // declaration for object of class extending JDialog
public MainProgram() { // constructor
myContainer = getContentPane();
showJDialogGUI(); // calls method to initialize
public void showJDialogGUI() {
enterGUIDialog = new enterGUI (this, true);
enterGUIDialog.setDefaultCloseOperation (DISPOSE_ON_CLOSE );
enterGUIDialog.setSize(200,200);
enterGUIDialog.setVisible( true );
enterGUIDialog.show();
} // end of class MainProgram
public class enterGUI extends JDialog{
Container myContainer;
JPanel myPanel;
//// How to call the constructor to create this JDialog????
public loginGUI( JRootPane theRoot, boolean theModal ) // passed in 'this', and 'true'
// or maybe??? public About(Frame parent, boolean modal) {
this.setRootPane( theRoot ); //???????
// or maybe ??? super(theRoot, flag);
//super(theRoot, flag); // calls Dialog class constructor
this.setModal( theModal ); // ?????
myContainer = getContentPane();
myContainer.setLayout( new FlowLayout() );
thePanel = new JPanel();
// next add components to JPanel, then add to the JDialog container
fieldsPanel.add( pageLabel ); etc.
myContainer.add( fieldsPanel );
// etc.
myContainer.setDefaultCloseOperation( DISPOSE_ON_CLOSE );
myContainer.setVisible(true);
} // end of constructor
// more methods etc
}

Error received is:
E:\Ghost>
MainProgram.java:670: cannot resolve symbol
symbol : constructor enterGUI (MainProgram,boolean)
location: class MyPackage.enterGUI
enterGUIDialog = new enterGUI(this, true);
'new enterGUI(this, true); ' seems to be at start of
error
TIAThe error message could not be any more clear. To wit: the compiler is telling you it cannot find a constructor for class enterGUI that takes as parameters a reference to a javax.swing.JFrame, and a boolean value. Supply the constructor and the error will not be raised.

How to set the value of something in a component from the main application?

Hi,
Maybe I've been working on this too long, but I can't figure
out how to set the value of the text property of a text input field
in a component from my main application in an mx:Script block. I
have a component called Login in the components folder, and I need
to set the text value of empNum. In my mxml declaration at that the
top, I've declared these components as xmlns:c="components.*" So
logically, the property I'm trying to set is c.Login.empNum.text. I
can't figure out the correct syntax to get this to work, and I've
tried everything I can think of. Does anyone have any suggestions?
I'm thinking this should be an easy one, and I'm just missing
something.
Thanks!
Holli

Did you try giving it an id ?
<c:MyLogin id="loginScreen" /c>
So later you can do loginScreen .empNum.text = "my text"
Laurent,

Best Practice in regards to adding showing SkinnablePopUp from the Main application file of Mobile A

Hello,
I want to display a SkinnablePopUp when the user presses the back key when the current view is the first view to ask if he wants to quit.
The logic (checking if the key pressed was the back key && the current view is the first view) is in the main application file and if those two conditions are true then the exit() method is called.
I want to show the confirmation popup. Should I move all that in the first view mxml component or is it OK to instantiate the SkinnablePopUp in the main app file?
Thank you.

so do I, or did, well still do but less than before
it seems best practice is to seperate mxml and AS3
have a look at this

Calling a component from a the main.mxml file

How do I call a component from a the main.mxml file?

    </mx:VBox>
Thank you

It won't see it just by creating the namespace that contains it. There has to actually be an instance of it in the application. So in your case, your main application file (lets call it MyApp.mxml) would look something like this:
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"
     xmlns:components="components.*">
     <components:Main id="main"/>
     <components:GetComponent id="getComp"/>
</mx:Application>
Then, you can reach down (mind you this isn't best practice) into those components to access their public properties. In a script block in MyApp.mxml, you could access the VBox with getComp.vbTB.
I don't know the ins and outs of your application, but perhaps Main is the main application, so then you would add GetComponent as a child of it instead of both Main and GetComponent being child components of the MyApp application. Does that clear up the confusion?

How to contain a sub-component in the module instead of containing it in the main application

Hi,
I've 3 files
Appln.mxml (application file) ---- contains main application
component.mxml (component file) ---- contains component
module.mxml (module file) ----- contains module
Generally the 'component.mxml' file will get loaded into the 'Appln.mxml' file (i.e., 'Appln.mxml' file will contain the custom component files) and whereas module file will get loaded on-demand.
So Now instead of containing the data of 'component.mxml' file in the 'Appln.mxml', I want to contain 'component.mxml' file data in the 'module.mxml' file itself and load the 'component.mxml' when module is loaded on-demand but not when application is loaded. So can any one please suggest me how to do it?
Thanks in advance..

You can delete software components & versions from the IR in XI 2.0. (We're on Service Pack 5, and I've done it to clean up our IR.)
Here is the process:
1. Delete all configuration and/or import objects from the SCV. Don't forget the 2 fault data types that SAP automatically creates in every namespace.
1a. Activate all change lists? I don't remember for certain if this is needed here; if it won't let you save the deleted namespaces in step 2, then do this first.
2. Double-click on the Software Component Version so that it comes up in the right pane. Click on the change/edit button. Delete all the namespaces from the SCV. Save.
3. Activate all change lists. (It won't let you delete the SCV if you have uncommitted changes.)
4. Open the SCV again (if it's not still open). On the menu at the top of the right pane, go to Software Component Version...Delete. You may or may not have to activate changes again.
If I remember right, the software component will disappear automatically with the deletion of the last version.
Hope this helps!

DataGrid SelectedIndices from a different MXML component

Hello
I am refreshing a data grid that resides in my main component, from a sub-component. This works if I invoke the web service method to rebind the dataprovider, and I do not reference the datagrid directly from the sub component.
My trouble is that I use checkboxes in my datagrid. I need to reset the selectIndices of the datagrid, but anytime I try to reference the datagrid directly it is NULL. The datagrid loses its checkbox selections every time I call the refresh, so I must explicitly reset the selectedIndices.
How can I reset the datagrid's selectedIndices from a different MXML component? Why is my datagrid always NULL in my web service's result event handler?
How can I directly reference my main component's datagrid, from my sub-component?

Hi Devtron,
You can figure this out by using events..
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" creationComplete="onCreationComplete();" xmlns:comp="comp.*">
<mx:Script>
<![CDATA[
   private function onCreationComplete():void
    comp2.addEventListener("refreshGridEvent",refreshGrid);
   private function refreshGrid(event:Event):void
    comp1.dataGrid.dataProvider = null;
]]>
</mx:Script>
<comp:Component1 id="comp1" />
<comp:Component2 id="comp2" />
</mx:Application>
Now in your Component2 dispatch the refreshGridEvent event either on a button click or when your UI elements changes based on your requirement...this.dispatchEvent(new Event('refreshGridEvent')); and listen for the evet in manin mxml file and change the dataProvider of the dataGrid in Component1.
Note: This solution is if your both components are placed in the main mxml file. Is your structure is same as I mentioned in the code above..I mean
whether your two components are placed in the main mxml file.
Thanks,
Bhasker

Access a component in an mxml file from a different mxml file

Hi,
I want to access a component in an mxml file 1 such as this one <mx:Image id="img" width="101" height="200" source="{product.image}"/> using the
id
from the actionscript function from a different mxml file 2
public function init():void
       HERE.addEventListener( MouseEvent.MOUSE_DOWN, beginDrag );
so i can make it dragable, Please help me in this if u can urgently!!!!

okay,
I have the image component in ProductCatalogThumbnail.mxml, which has an id of "img"
so, i created a public variable in the file and a public function that returns the value of the object.
public var imagecopy:Object;
        [Bindable]
         public function imagecopyfunction():Object{
         imagecopy = img;
         return imagecopy;
now, I want to access this image in the mxml file ProductList.mxml in a function
public function init():void
      ProductCatalogThumbnail.imagecopy.addEventListener( MouseEvent.MOUSE_DOWN, beginDrag );
   // accepting a drag/drop operation...
     this.area.addEventListener( DragEvent.DRAG_ENTER, acceptDrop );
     // handling the drop...
    //this.area.addEventListener( DragEvent.DRAG_DROP, handleDrop );
I tried to use the variable, and then i tried to use the function:
I got this error when I tried the variable : 1119: Access of possibly undefined property imagecopy through a reference with static type Class.
ProductCatalogThumbnail.imagecopy.addEventListener( MouseEvent.MOUSE_DOWN, beginDrag );
and this error when i tried the function: 1061: Call to a possibly undefined method imagecopyfunction through a reference with static type Class.
ProductCatalogThumbnail.imagecopyfunction().addEventListener( MouseEvent.MOUSE_DOWN, beginDrag );
i made sure i imported ProductCatalogThumbnail file in the beginning of my application.
I am not sure what went wrong.
