Hierarchy with as3 coding and to remove children

To give a brief overview of what's going on here.  I'm building a personal site where I have a navigation, and I have other subnavs inside some pages.  Such as if I'm going to 'work' inside job I 'motion', 'web' and 'print '.  Some examples of code to a button on the navigation:

nav_mc.personalbtn_mc.addEventListener (MouseEvent.CLICK, buttonClick2);

function buttonClick2(event:MouseEvent):void {}

gotoAndStop ("personal");

function workss_mcExists (): void {}

if {(workss_mc.stage!=null)}

trace ("YES workss does exist");

removeChild (workss_mc);

{ } else {}

trace ("NO workss does not exist");

}

}

workss_mcExists();

function motionss_mcExists (): void {}

if {(motionss_mc.stage!=null)}

trace ("YESdudemar");

removeChild (motionss_mc);

} else {

trace ("NO");

}

}

motionss_mcExists();

function workExists (): void {}

if {(work_mc.stage!=null)}

trace ("YES");

removeChild (work_mc);

} else {

trace ("NO");

}

}

workExists();

function objectExists (): void {}

if {(workss_mc.stage!=null)}

trace ("YES");

removeChild (workss_mc);

} else {

trace ("NO");

}

}

objectExists();

function home_mcExists (): void {}

if {(home_mc.stage!=null)}

trace ("YESdudemar");

removeChild (home_mc);

} else {

trace ("NO");

}

}

home_mcExists();

function workpersonalExists (): void {}

if {(workpersonalss_mc.stage!=null)}

trace ("YES");

removeChild (workpersonalss_mc);

} else {

trace ("NO");

}

}

workpersonalExists();

}

It seems to me that actionscript will read all the way down to the bottom when looking for objects.  For example: the first if statement where she asked if workss_mc exists or not, which works if it is upstairs, but if I move it to the bottom, it won't work.  Does anyone have any idea how to fix this or bypass?

Thanks in advance!

This is the correct code, but if you goto a frame whereunimetal_homeref_mc doesn't exist, you'll still get an error message.

to remedy this, you could declare all your clips as part of this code and then check if the object is null:

var unimetal_homeref_mc:MovieClip;

unimetal_homeref_mcnav_mc.workbtn_mc.addEventListener(MouseEvent.CLICK, buttonClick1);

function buttonClick1(event:MotionEvent):void {     gotoAndStop("work");     stage.invalidate();     stage.addEventListener(Event.RENDER,renderedF);}

function renderedF(e:Event) {     unimetal_homeref_mcExists();}

function unimetal_homeref_mcExists():void {if(unimetal_homeref_mc!=null){     if (unimetal_homeref_mc.stage!=null) {          trace("YESdudemar unimetalhomeref exists");          removeChild(unimetal_homeref_mc);     } else {          trace("NO home ref does not exist");     }}}

    Victor,

    If a raster image, it is much better to do it in Photoshop.

    If it is a vehicle for work on top of a color, you should be able to simply select the live/outline Type object and delete it. If this is a carving, you should be able to select the routes involved and the Pathfinder > unit. Or something else.

  • How to remove children lines with removal of multi line?

    Hello!

    I have a DSM process that removes the selected lines of the report, but it gives an error if the line have a child row in another table, so I have to go to this report and remove these first.

    Just add somewhere in the DSM process something then it removes children lines too, or I have to create new process for this?

    Hi EgaSega,

    DELETE will work if there is no foreign key constraints that refer to the line to remove.

    If you don't have foreign key constraints, you can change them to 'ON DELETE CASCADE '. This way, if you DELETE a row in a parent table, all child rows will be auotmatically DELETED, too.

    There are also "ON DELETE SET NULL', which allows you to DELETE the parent rows with children. When you DELETE a parent, child rows are not automatically DELETED, but the columns that pointed to the DELETED parent are automatically changed to null.

    Check out this old thread of discussion forum SQL and PL/SQL for more details:Delete record based on the ID of the main table

    Hope this helps you,

    Kind regards

  • Parental and child control with AS3

    Hello

    I am new to AS3 and although I can see some good practices and functionality, I'm constantly stuck and can still do the things I would do if easily with AS2 - I almost it relearn from scratch!. I would still appreciate little help and advice on this...

    I did a class that creates a "sort" menu with data from an XML file, and basically is what he does when he is called to create an emptyMC (a container), add a childMC (a square) and add another child (a text label). When I create the container, I am trying to add a MouseEvent that can act on each instance of container, but all I can get is a MouseEvent on the object that contains all the MCs added. The code follows.

    Can someone enlight me with that issue or explain what I am doing wrong.

    I do not understand the parental dynamics with AS3 and the absence of the use of instance names and parenting dot does not help.

    Thanks in advance.

  • Is it possible to buy a new computer with Windows XP or buy one with Windows 7 and remove it and install Windows XP? I have

    I now have a computer with Windows XP and wanted to buy a new computer.  All new computers come with Windows 7.  Is it possible to buy a new computer with Windows XP (or buy one with Windows 7 and remove it and install Windows XP)?   I like XP and have talked to people who are not really happy with Windows7 and holds XP back.  AND I also discovered that my printer is not compatible with Windows 7 - it is not that I love him and want to keep it.  I can't afford to buy a new computer AND printer, since I have been unemployed for more than 2-1/2 years.   I would like to use XP on a new computer!   I would appreciate it if you could let me know what is possible or if I'm stuck with my old computer.  Thank you very much!

    Probably not, you will find a computer with XP on it.

    If you buy a computer with Windows 7, you will first need to know if it would be compatible with Windows XP. Probably not, because they are not designed for XP and drivers are not available.

    Unless you want to spend the time, you're stuck with your old computer.

  • How to validate and save the values to a combo box and two text boxes in flex4 mxml application with as3

    helllo all,.

    I'm working on the application web flex4 with as3.

    I have a doubt, I've created a mxml it has two text boxes, except the button and a combo box that is has two option as a percentage and the amount.

    my needs are I gave here.

    need 1: when I choose option amount that two text boxes does not have to be editable.when I select text tat box two percentage option will be editable.

    need 2: when I select the percentage in combox option and two text boxes are empty, and then click the button Save-> I want to display warning msg

    need 3: when I select the option amount combox and the two boxes are emptu click the button Save-> I don't want any warning messages.

    How to validate it and how to write backup for this function.

    any suggession or extract code is welcome.

    Thanks in advance,

    B.Venkatesan

    Looks like you are trying to do too much at once. Try to hang the events correctly

    The close event of the comboBox can do something like this

    protected function toggleTextEditing(event:DropDownEvent):void

    {

    If (this.optionCmb.selectedItem.label is "Percentage")

    {

    This.Text1.editable = true;

    This.Text2.editable = true;

    }

    Else if (this.optionCmb.selectedItem.label == "Number")

    {

    This.Text1.editable = false;

    This.Text2.editable = false;

    }

    }

    The button's click event can do something like

    protected function save(event:MouseEvent):void

    {

    If (this.optionCmb.selectedItem.label is "Percentage")

    {

    If (this.text1.text == "" & this.text2.text == "")

    {

    Alert.Show ("text is empty");

    return;

    }

    on the other

    {

    }

    }

    Else if (this.optionCmb.selectedItem.label == "Number")

    {

    }

    }

    If you can put in your entire code, maybe I can have a look to see if I can find something wrong with that.

  • FlexUnit with AS3 AIR does not work?

    Recently, I tried to take a shot at TDD (Test Driven Development), as I'm sure many of you know.  To do this I tried to use FlexUnit 4 of in Flash Builder 4.

    If I create a project as follows:

    1. New--> Flex project
    2. Next, Next
    3. (The main Application file) Replace .mxml, .as
    4. Finishing

    Then when I try to use FlexUnit in the ordinary way, it fails to generates an adequate FlexUnitApplication.mxml.  The content of this file is:

    

package_declaration
{
class_declaration
{
class_body
}
}

    Therefore, there is a compile error that I can not move:

    Content is not allowed in prolog.

    However:

    If I followed the same process as above, without changing the .mxml to .as tests run correctly.

    Things, I tried to work around the error:

    • FlexUnit to 4.1 update
    • Pressing refresh in the FlexUnitsResults window
    • Creating a project with .mxml and thereafter remove this mxml and its replacement with an actionscript class
    • Bump on my desk.

    None of them have worked.

    Did anyone here successfully FlexUnit FlashBuilder 4 for an AS3 AIR project all?  If not, can anyone suggest another Test package?

    Thank you

    ~ Nick.

    I found a solution at least provisional.  I restarted FlashBuilder and despite the error marked under issues here and it worked.

    I think that restart Flashbuilder maybe erases a previously stored properly compiled build.  (Maybe Clean could also do this?).  in any case, at the time of compilation, the mxml file was generated correctly and all is well.
