Is there an updated Language Reference available for MinimalComps, and would it be possible to place it either in the project folder or the "downloads" section?

There is one available at http://www.minimalcomps.com/documentation/ but (1) it hasn't been updated since May 2010 and (2) is not downloadable for offline viewing.

The list scroll to selection isn't working, meaning that scrolling up and down with the arrow keys, or setting the selected index directly won't work.

On line 173 of List.as, the scroll up is commented out, while the scroll down needs to be modified.

Something like this seems to work:

protected function scrollToSelection():void
{
           var numItems:int = Math.ceil(_height / _listItemHeight);
            if(_selectedIndex != -1)
            {
                if(_scrollbar.value > _selectedIndex)
                {
                    _scrollbar.value = _selectedIndex;
                }
                else if(_scrollbar.value + numItems <= _selectedIndex + 1 )
                {
                    _scrollbar.value = _selectedIndex - numItems + 1;
                }
            }
            else
            {
                _scrollbar.value = 0;
            }
            fillItems();
}

Just running an example in MinimalConfiguratir, and noticed when running the default example 2, input text get OVER label text within a .
This is easily fixed by adding a width to the label, like:

instead of:

I've tried it both on Flash Player 11 and Flash player 10.2

It looks from the XML that the two vbox instances should sit side by side in the hbox, but the first vbox is covered by the second:

I had to add a width attribute to the first label to make it behave - not sure if this implies a problem with the layout algorithm of the hbox or not.

I'm very thank you for these great components.
When I set items of List, I get a exception. I added a line(makeListItems) and the problem's solved.

original:
public function set items(value:Array):void
{
_items = value;
invalidate();
}

code I changed:
public function set items(value:Array):void
{
_items = value;
makeListItems();
invalidate();
}

Is it okay?
thanks. :D

in onMouseGoDown:
stage.addEventListener(MouseEvent.MOUSE_UP, onMouseGoUp);
(and corresponding removeEventListener in onMouseGoUp).

Is there a special reason this listener is added on "stage" and not "this"?
This caused some problems for me when I had another stage mouse listener
(the button would not get the mouse up event and stay _down).

If I change this listener to register on this (the button) everything works fine.

Thanks,
Ori

Hello,

I'm enjoying the new MinimalConfigurator, but with the new version I've run into a little problem with the HBox component.
Using this Example Two on minimalcomps.com MinimalConfigurator page(http://www.minimalcomps.com/?page_id=14):

The second VBox isn't displayed at the right of the first VBox. This behaviour can be viewed on minimalcomps.com,
but it seems fine in your initial blog post (http://www.bit-101.com/blog/?p=2961/), which I imagine uses a slightly older version (maybe 0_9_9 ?)

I can resolve the issue if add an Id to the HBox node and then use the getCompById() method to reference it and call draw() on it again, but I wish there was a cleaner fix for this.

Hello Keith,

I've run into another issue, but not sure how severe it is.

This snippet:

var ls:List = addChild(new List()) as List;
ls.items = ['item1','item2'];

causes this error:

Exception fault: RangeError: Error #2006: The supplied index is out of bounds.

This is using MinimalComps_0_9_10.swc, the issue is not present when I use MinimalComps_0_9_9.swc though.

All the best,

a click listener is added if defaultHandler is not null...
if(defaultHandler != null) { addEventListener(MouseEvent.CLICK, defaultHandler); }

thought i didn't see the listener being removed anywhere... and since weak reference is false by default maybe it should be
if(defaultHandler != null) { addEventListener(MouseEvent.CLICK, defaultHandler,false,0,true); }

I wrote a class that might help finding other memory leaks called EventManager http://k2xl.com/wordpress/2008/07/02/as3-eventmanager-class-removealllisteners/

Hi! Why do you call _tf.setTextFormat(_format); on every draw() call? You could use _tf.defaultTextFormat = _format once at the addChildren method. And it seems that html text rendering is not compatible with text format (I can't change a text color with a tag).

I was wondering about the memory managment and possible memory leaks of this library.
Is it enough to just remove a display object from the stage to free up the memory??

For instance, I had a look in the PushButton.as class:

        if(defaultHandler != null)
        {
            addEventListener(MouseEvent.CLICK, defaultHandler);
        }

as far as I can see the defaultHandler is never removed from the pushbutton, and there is no way of removing it either, as the handler is an anonym function and not saved.

Wouldn't that mean that it will stay in the memory indefinitely, and cause a memory leak?

Create a new list with a small number of items (or null):

Set the items property to a larger array:

myList.items = a;

It crashes around line 135 in fillItems() with an index out of bounds exception:

I'm assuming it's trying to reuse previous ListItems instead of creating new ones, but no check is ever made to see if they exist.

It would be great to able to add some formatting to the TextArea.

The below gives this error:
Error: Error #2009: This method cannot be used on a text field with a style sheet.
at flash.text::TextField/setTextFormat()

                    /////code to cause error/////
                    style = new StyleSheet();
        heading = new Object();
        heading.fontWeight = "bold";
        heading.color = "#000000";

        body = new Object();
        body.fontStyle = "regular";

        style.setStyle(".heading", heading);
        style.setStyle("body", body);
        //end stylesheet

        scrlTxtArea = new TextArea(this,30,310,"");
        scrlTxtArea.html = true;
        scrlTxtArea.width = 489;

        scrlTxtField = scrlTxtArea.textField;
        scrlTxtField.styleSheet = style;

NumericStepper height should be 16 pixel, but when you add the NumericStepper into an empty Sprite, the sprite height become 100 pixel where it should be 16 pixel.

With the code:

this.m_combo = new ComboBox( this, 10.0, 10.0, "TestRemove", ["one", "two", "three"] );
this.stage.addEventListener( KeyboardEvent.KEY_DOWN, this._onKeyDown );

private function _onKeyDown( e:KeyboardEvent ):void
{
this.m_combo.removeItemAt( 0 );
}

It initially displays a list with the items "one", "two", and "three". When you hit a key, it's meant to remove the first item. As far as I can tell this works, but when you open the drop-down, it's now "two", "three", "three" - it's not removing the old ListItem.

This bug isn't present in v0.9.9

With the code:
var a:Array = new Array( "hello", "world" );
var c:ComboBox = new ComboBox( this, 10, 10, "Hello world:", null );
c.items = a;

MinimalComps throws a RangeError in List.fillItems() - specifically the getChildAt() call.

The full error:
[Fault] exception, information=RangeError: Error #2006: The supplied index is out of bounds.

This wasn't present in v0.9.9. It also only throws this if you set the ComboBox items array as null in the constructor.

Right now you can minimize/un-minimize as window without it moving to the top of the view stack. This seems incorrect.

I'm happy to fix this in the code - i'll attach a pull request once i've committed it.

In the 0_9_10 swc:

var myList:List = new List(contents,0,0); //I have no initial items, so I leave the final arg empty
myList.addItemAt("Foo",0); //I add at 0, because i want new items to be at the top of the list.
myList.addItemAt("Bar",0); //Second time causes an index out of bounds error
