Using ScrollPane in Flashbuilder
Hi,
if i follow the example in the API. I can't get a ScrollPane to work.
I import fl.containers.ScrollPane but FlashBuilder4 says it can't be found.
That the rest can't work is obvious.
How can I work with ScrollPanes only using FlashBuilder?
If you must use Flex 3 but want to use Flash Builder 4, you can choose the 3.5 SDK when you create a project in Flash Builder, and you will be building a Flex 3 project and all the old videos should work for you.
If you want to use Flex 4 and Flash Builder 4, then I suggest you learn from the Flex 4 and Flash Builder 4 videos (http://www.adobe.com/devnet/flex/videotraining/). That way there won't be any confusion between the old and new versions.
You can download the solution files for any of the exercises. The one called "Adding data to your application" will help you populate a DropDownList control. HTHs.

How to scroll panels using scrollpane?
i am having two panels containing different images in a main panel.
my problem is that due to big size only one panel is visible in run time so i want to add scrollbar to the main panel.
i have used scrollpane for the main panel but i am getting confused that at which event i should put the code of repainting the visible area.
can anybody tell me how to implement this.
plz... helpgaurav_mishra wrote:
actually i am working in netbeans so i don't know where is the paint method of the panel.can anybody plz help me get rid of this problemApparently we were all mistaken by your description, it looked like you were writing a custom JPanel subclass, with a custom paintComponent() method that would draw the images...
I don't know how you display images in a Panel with NetBeans, but presumably it re-uses some existing JComponent and it doesn't have to generate a paintComponent() method.
At that step you should consider the very first reply: please post some code, the shortest running example that demonstrates your problem.
If you're reluctant, try a simple scroll example: put a single JButton in a JPanel with a FlowLayout, using an image as the button's icon. Stuff this panel into a JScrollPane, itslef in a JFrame, run the app and resize the JFrame. Check whether the button displays appropriately. If it does, try to check what's different with your problematic case.
I like NetBeans (or merely, NetBeans's GUI designer), but it's not the best way to learn Swing programming, which looks like what you're doing. -
Hi All
Let me explain the problem to u guys..
I have a dialog whose contentPane is set to BorderLayout.A scrollPane is added to this dialog.Next a Panel is added to this ScrollPane and the panel is having a gridbaglayout.Some components are added to this Panel is rows and columns dynamically,everytime new components need to be added the old components are removed using removeAll.The scrollPane is having VERTICAL_SCROLLBAR_AS_NEEDED and HORIZONTAL_SCROLLBAR_NEVER (The component is given a fixed prefferedSize,MaximumSize and Minimum size).The problem is I am not getting to view all the components widthwise,vertically its OK since I have a scrollBar.I want all the compnents in the row to be displayed within the viewport area.
Is it bcoz of fixed preferredSize,maximumsize and minimum size of componets that i am not getting to view them fully?Please give me a solution as to how i can solve the problem
regards
OliverI would suspect the gridbag layout. If you add a horizontal scrollbar (just to find out what's going on), can you see all the components? Maybe you can post some code for us to look at. . .

I cant use ScrollPane in JList
JList list=new JList(kaynak);
list.setBounds(0,0,40,40);
JScrollPane sc=new JScrollPane(list);
add(list);
add(sc);
setVisible(true);
why I do not have scrollBars arround my jlist? what is the problem?JList list=new JList(kaynak);
list.setBounds(0,0,40,40);
ScrollPane sc=new JScrollPane(list);
add(list);
add(sc);
setVisible(true);
why I do not have scrollBars arround my jlist? what
is the problem?You've added the list to the scroll pane, but then you add the list to the frame. And then you add the scrollpane to the frame.
This approach contains two flaws:
A. You can't add a component to two different parents. When you try to do so, the component is removed from the original parent and added to the new parent. So, when your code says
add(list);the list is removed from the scrollpane and added to the frame.
B. You can't add two different components to the same container without indicating where to put them. Assuming your container has a default BorderLayout, your code adds the list at the CENTER position, and then adds the scrollpane at the CENTER position. As a result, your list is removed from the container and the scrollpane is added. but since the first flaw in your code removed the list from the scrollpane, nothing appears. The scrollpane is there, but it has nothing in it so the frame appears empty.
Remove the line:
add(list);and things should work.

Using FlashBuilder 4 with Flex sdk 3.5
Has anyone experianced any problems with using the new FlashBuilder 4 together with the Flex 3.5 sdk?
I have not had any issues so far in the short time I have used FB4.
I would like to use the new FB4 IDE but cant upgrade the SDK at the moment.
It will potentialy also be an environment with mixed IDEs using both FB3 and FB4.
So I am wondering if there are any known issues with the set up FB4 + sdk3.5 in general. -
Updating player version used in FlashBuilder
hallo people,
i'm trying to use OSMF in FlashBuilder 4 but i encounter this error ...
I configured Flex SDK for my project to include Flex 4.1(C:\flex_sdk_4.1) but when i try to launch my project i get this error box:
C:\flex_sdk_4\runtimes\player\10\win\FlashPlayer.exe
This project requires a more recent version of the Adobe Flash Player. You might need to install the Flash Player or reinstall Flash Builder.
Installed Adobe Flash Player version: 10,0,45,2
Required version: 10,1,0,0
Do you still want to launch the application?
why FlashBuilder is still looking at C:\flex_sdk_4......?
anyone can help me?
thanks a lot
gpleoneYou could use field-symbols.
like
DATA: l_text(18) VALUE '(SOURCE_PROGRAM_NAME)table_name[]'.
field-symbols <fs> type table.
Assign (ltext) to <fs>.
if sy-subrc eq 0.

hiii i am creating an image editor in java...
here is my code for using scrollpane
contentpane = getContentPane();
view = new JLabel(new ImageIcon(bufferedImage));
scrollpane = new JScrollPane(view,ScrollPaneConstants.VERTICAL_SCROLLBAR_ALWAYS,ScrollPaneConstants.HORIZONTAL_SCROLLBAR_ALWAYS);
scrollpane.setPreferredSize(new Dimension(800,600));
contentpane.add(scrollpane);The problem is that the content of viewport does not change...i.e if i apply any effect to an image....after that as soon as i use the scrollbar, the viewport displays the original image!!!
What is the problem??
could someone suggest a solution?Can you plzz help me with this??...it is very urgent...
As i am creating an image editor, so the scrollpane must be updated as soon as i apply any effect to it .....
along with that whenever a user selects a file from FileDialog...then also it must be updated!!!
I have extended JFrame for my main class.
//this is the code i have written when user selects a new file...
contentpane = getContentPane();
view = new JLabel(new ImageIcon(bufferedImage));
view.setVisible(true);
crollpane = new JScrollPane(view,ScrollPaneConstants.VERTICAL_SCROLLBAR_ALWAYS,ScrollPaneConstants.HORIZONTAL_SCROLLBAR_ALWAYS);
scrollpane.setPreferredSize(new Dimension(200,200));
contentpane.add(scrollpane);
// This is the code for scollpane update
iicon.setImage(bufferedImage);
view.setIcon(iicon);
scrollpane = new JScrollPane(view,ScrollPaneConstants.VERTICAL_SCROLLBAR_ALWAYS,ScrollPaneConstants.HORIZONTAL_SCROLLBAR_ALWAYS);
scrollpane.setPreferredSize(new Dimension(200,200));
contentpane.add(scrollpane);
scrollpane.updateUI();Message was edited by:

Hello, this is my first post.
I'd like to add zoom in/out function to my ScrollPane, and make shortcut (CTRL+MOUSE SCROLL UP/DOWN) for it. ( like Inkscape )
I made the following code ( Canvas ) to achieve this, but have some problems.
*1. How can I prevent ScrollBar's thumb to move when pressing CTRL?*
When ScrollBar is visible and ScrollBar's thumb (or scroller, knob) has room to move, CTRL+MOUSE SCROLL UP/DOWN doesn't work because the thumb moves instead of zooming in/out.
When the thumb moves up/down to bar's end, then zoom in/out finally works fine.
*2. ScrollEvent handler is sometimes not called in ScrollPane*
When ScrollBarPolicy is not ScrollBarPolicy.ALWAYS and Scrollbar is not visible, SOMETIMES CTRL+SCROLL UP/DOWN operation dosen't work.
(ScrollEvent handler is not called. For other panes, ScrollEvent works fine. Please check MouseScrollEventTest below)
Thank you in advance.

Resizing ScrollPane and Dimension dynamically
I am currently making a scrollbar program using ScrollPane and Dimension. I have to use those classes.
When I click "ok" button, that calls dc.enlarge(500,800) method. But it doesn't work.
When it is clicked, Dimension object should be changed and the panel has to show Horizotal
and Vertical scrollbar according to the width and height parameters.
Of course, the size will be calculated by the String contents object's rows and width. But it does not work.
How to resize the Dimension and How to display the Horizontal, Vertical scrollbar accoring to dc.enlarge's parameters?

ScrollPane in Flash MX and flash Mx 2004 professional
Summary:
The refreshPane method works differently in Flash MX and
Flash MX 2004 Professional
What went wrong?:
I have used scrollPane component in Flash mx and loaded some
content. I changed the content size i.e. width and height
at runtime and after that called the refreshPane() method to
resize the scrollPane. It works fine with Flash MX
But same I tried with Flash Mx 2004 Professional, but it
doesn't work, since in Flash Mx the refreshPane() method resizes
the content and in flash Mx 2004 Professional the
refreshPane() metod reloads the content.
What should have happened?:
Can there be a method in flash Mx 2004 Professional which
just resizes the scrollPane and not reloads the whole content?
Since if I have to generate a content at runtime and resize
it also at runtime then just by calling the method refreshPane() in
flash Mx 2004 Professional, it loads the content what it was
originally and not the changed one.
Product version: flash Mx, Flash Mx 2004 Professional
Product: Flash
Component: scrollPane
I would like to request you to help me in the same as early
as possible.
Thanks and regards,

Flash MX creates .swf files. Dreamweaver CS4 creates HTML
files, and
has the capability of inserting .swf files in a web page. It
doesn't
matter which version of Flash you use to create your .swf
files; they
can be inserted into a web page in any version of
Dreamweaver.

Android Air App using AdMob "NULL Object" Error?!?
Hi,
I am currently developing an app using adobe air flashbuilder and I have incorporated AdMob type html adverts into it. The Adverts do come up nicely however if I run the app in debug mode I get this error:
TypeError: Error #1009: Cannot access a property or method of a null object reference.
at model::AdMob/createAd()[C:\Users\Jack\Documents\Dropbox\Projects\App\App Final\src\model\AdMob.as:37]
The Ads do still work regardless of this however this is then affecting other elements within the app so I would like to get rid of the error that is happening. Below is my code in the "AdMob.as" file where I believe the issue to be occuring, can someone please help me with this?

Flash mx -ScrollPane - scroll bar issue
If we create some dynamic content and display it using
scrollPane and if the width and height of the clip( the clip
displayed in ScrollPane) changes dynamically by clicking on a
button then refreshPane method does not work properly. We have to
set original position of the clip to (0, 0) when scroll bar
(vertical/ horizontal) disappears. I think this is not a good idea
to work around with scrollPane.
Let me know if there are any efficient methods with which we
can handle dynamic data in scrollPane to display it properly.
Thanks in advance,
ShreeramHi,
Thanks for your co-operation. Please let me know if
Macromedia Team fixes this bugs. Till then please let know about
any methods or any solutions if you know.
thanks

How I use swf in swf (nested) ?
Flash is case-sensitive in naming(symbols,form
fields,components) ?
How I use ScrollPane ?
How I use swf in swf (nested) ?What I've done in the past is created an image using an image editor like MS Paint, then change the image to black/white instead of color, and used grey instead of black. Then upload the image via SE78. Then you can include the image in your sapscript using the BITMAP statement. Search for watermark in this forum and you should get some more info.
