How to initialize form elements?
Hello
I need to create the popup with several shapes. As is the popup do not add it to any component - just create it with the "new" operator The problem is that childern of all pop-up window are null until I have add window in some components. I found that there is initialize() function which should create children of the window everything and it does but only children who are not childern of the form.
Exaple below saveButton and cancelButton will be created after window.initialize () but addPhotosButton not.
< s:Panel >
< s:VGroup >
< mx:Form >
< mx:FormItem >
< s:Button id = "addPhotosButton" / >
< / mx:FormItem >
< / mx:Form >
< s:Button id = "saveButton" / >
< s:Button id = "cancelButton" / >
< / s:VGroup >
< / s:Panel >
I need to have the window all children created without adding it but do not know how...
Could someone help me, please?
As you use the MXML file for the implementation of your form, Flex compiler generates AS3 code that follows the rules of the normal cycle of component: all the components are created in the method createChildren() () when you add the element to the display list. To work around this problem is to implement your form in pure AS3 and creating all things in the constructor.
The best approach would be to create the instance of the component, add event listener for CREATION_COMPLETE (you can also use INITIALIZE) event, add your component to the display list. When you receive the event, it is safe to do everything you need with this component and its children.

You can also use APEX_UTIL. GET_SESSION_STATE

space vertical theme 24 between form elements
Hello
How can I increase the vertical spacing between the 24 theme form elements? I currently use the following to change the style of the single display items. I tried to add 'margin', but did not work.
< pre >
< style type = "text/css" >
span.display_only {border: 1px solid #D4D0C8; padding: 5px 10px ;}}

span is an inline element so no vertical margin is applied. Change the view type to generate a block box:
span.display_only { display: block; margin: 10px 0; border:1px solid #D4D0C8; padding:5px 10px; }

How can I form an image?
How can I form an image as above?
Dina,
But now, how can I do the corrugated and smooth points like in my picture? And also, I now want to change certain points, like moving a little upwards or downwards... but I tried and it does'nt work. Maybe just, I want to move a point, and not the whole picture.
You can do so by creating the path to start with:
(A) by shaping it with the pen tool (which takes a bit of practice which is necessary for any user). You create Anchor Points to a limited number of positions along the way, the pieces together as segments and you click to create straight segments/sharp corners and/or ClickDrag to create curves segments/edges rounded; the landslide creates the lines of Direction with handles that govern the shape of the segments; If you want to adjust the position of an anchor Point when creating it, you can press the space bar and move on, before you finalize the landslide or just let it go,
(B) by putting in shape with another tool such as pencil, where you draw more as normally by hand.
In all cases, you can change the path in the future. Speak in a certain way, you can insert Anchor Points by clicking/ClickDragging with the tool, add anchor point, moving from the corner and smooth with the tool points convert to an anchor Point, select Anchor Points specific smoothly with the direct Selection tool and drag the handles, ClickDrag with the tool remodel somewhere on a segment; These tools are supplied with the pen tool and the tool of the scale.
And another problem... I want to cut a picture with the scissors tool. but it does not work! Really complicated! Why? How can I cut a picture?
To Illy, a raster image is not a collection of pixels that can be individually / easy to handle, as is the case with Photoshop: him, they are objects, sometimes troublesome objects, which cannot be modified as a whole in some way. And that's where the clipping mask happens to hide unwanted parts (which are still there).
There is a dirty, destructive way and little messy, it can get rid of the elements unwanted outside the Clipping Path, but if you want to cut a raster image, just like in Photoshop, you will need to do here.

Auto alignment and sizing in form elements - cannot turn off
For some reason any form I'm working on Acrobat 9 Professional on Mac, Leopard 10.5.8, has a problem.
It has a feature enabled, I can't understand how to disable. Form items sizes and positions are not adjustable in the range micro as usual. A button is a given height and can be set to two or three times (etc.), this height. Similarly, it cannot be moved in increments of same. It cannot be pushed.
I'm used to be able to move with the mouse or the arrows such small increases that form elements seem infinitely adjustable in size or position.
Is there a setting somewhere that disables this feature?
See the PDF attached with transparent buttons on the first page (TOC).
Thank you

the html form element attributes
Hey guys,.
Have a question about the attributes of the html form element
For a P1_Code element, I have an onchange = attribute "f_TestOnDemand (this.value)" "
Now if I want to add another attribute to the same P1_Code element, how to combine the two
the two attributes that I want to include for the same item are:
OnChange = hilitebtn (this.value)
OnChange = "f_TestOnDemand (this.value)" "
Thank you guys
Appreciate your help
JeshJesh salvation,
You must specify JavaScript functions in a defined mode of semcolon. In your example it will be as follows.
onChange = "hilitebtn (this.value); f_TestOnDemand (this.value)" "

2 How to remove an element from the tree and the database block tree?
Hello
2 How to remove an element from the tree and the database block tree?
Kind regards
Abdetu...The problem is caused by not sending forms is not a VALIDATION of the database because he thinks that there is no changes to save.
Forms does know that changes to the data block, he does not know the changes made by the PLSQL INSERT, UPDATE, DELETE calls and procedure.
Try to remove the line to block, rather than using a DELETION like that...
go_block ('INSP_EQUIPMENT_TYPE');if form_success then do_key ('DELETE_RECORD');end if;
If you wish to continue using your original DELETE instead of my change above code, you can use different techniques to force forms to issue the COMMIT to the database, including this one...
DELETE ... FORMS_DDL ('COMMIT');
Be careful... This will be the VALIDATION of the database, but the changes to the data block will not be sent to the database!
I posted a few other ways to issue a VALIDATION of forms here
