Corona widget.newButton change defaultFile - widget

Considering I am defining some button like the following:
-- title button
titleButton = widget.newButton{
label="",
width=265, height=70,
defaultFile = "images/title.png",
overFile = "images/title_clicked.png",
onEvent = handlePlayEvent
}
titleButton:setReferencePoint(display.CenterReferencePoint)
titleButton.x = display.contentWidth / 2
titleButton.y = display.contentHeight / 4
Is it possible to modify the button's defaultFile and overFile after creation from some other function.
I have searched the docs and couldn't find anything. Any tip would be appreciated

You can't change defaultFile and overFile after its creation.
Like display.newImage(), you can't directly change the image itself unless it is an image sheet.
But you can use image sheet as a button. You can change its frame whenever you want.

How to update the color of (the state of) the cell during resize in mxgraph?

I want to change the color of a state of a cell during resize of the cell.
To achieve this, I have added the following code to mxVertexHandler.prototype.updateLivePreview:
mxVertexHandler.prototype.updateLivePreview = function (me) {
...
this.state.x = this.bounds.x;
this.state.y = this.bounds.y;
this.state.origin = new mxPoint(this.state.x / scale - tr.x, this.state.y / scale - tr.y);
this.state.width = this.bounds.width;
this.state.height = this.bounds.height;
...
this.state.shape.fill = "#CCCCCC";
this.state.shape.fillOpacity = 30;
...
}
What happens is that this code changes the opacity of the cell while resized, but does not change the fill color.
How can I cange the fill color too?
Thanks,
-- Jaap
No, that does not work either.
BTW, I thought that temporal changes, e.g. during a resize, should go via the state.
I do not understand why fillOpacity (and other properties) works, and fill not. It seems that the fill is overwritten somewhere else (e.g. after calling updateLivePreview), but I can not figure out where.

Masked images not displaying in AS3

I am trying to mask an image on another so that I only view the specific portion of the unmasked image through the masked one. My problem is that I cannot see anything on the screen.. no Image, no effect at all
cardMask = new Image(Root.assets.getTexture("card_mask"));
cardMask.y = Constants.STAGE_HEIGHT*0.40;
cardMask.x = Constants.STAGE_WIDTH *0.48;
trace("it's add mask");
cardLight = new Image(Root.assets.getTexture("card_light_mask"));
cardLight.y = Constants.STAGE_HEIGHT*0.46;
cardLight.x = Constants.STAGE_WIDTH *0.48;
cardLight.mask=cardMask;
maskedDisplayObject = new PixelMaskDisplayObject(-1,false);
maskedDisplayObject.addChild(cardLight);
maskedDisplayObject.x=cardLight.x;
maskedDisplayObject.y=cardLight.y;
maskedDisplayObject.mask=cardMask;
maskedDisplayObject.blendMode = BlendMode.SCREEN;
addChild(maskedDisplayObject);
First, for masking an object the mask object should also be added to the display list. Your code does not add cardMask to display list anywhere. Second, if your maskedDisplayObject should be visible at all times, the mask should be assigned not to it, but to some other object which displayed part you desire to control. And third, it is also possible that this.stage is null, therefore the entire tree (this -> maskedDisplayObject -> cardLight) is plain not rendered. You need to check all three of these conditions to get something displayed.
Also, if you desire cardLight as an object to move independently of maskedDisplayObject, you should add it to this instead, and check that it's displayed on top of maskedDisplayObject (call addChild(cardLight) after addChild(maskedDisplayObject)).
This all totals to this code:
trace("Stage is null:", (this.stage==null)); // if this outputs true, you're out of display
cardMask = new Image(Root.assets.getTexture("card_mask"));
cardMask.y = Constants.STAGE_HEIGHT*0.40;
cardMask.x = Constants.STAGE_WIDTH *0.48; // mask creation unaltered
trace("it's add mask");
cardLight = new Image(Root.assets.getTexture("card_light_mask"));
cardLight.y = Constants.STAGE_HEIGHT*0.46;
cardLight.x = Constants.STAGE_WIDTH *0.48;
cardLight.mask=cardMask; // this is right
maskedDisplayObject = new PixelMaskDisplayObject(-1,false);
// maskedDisplayObject.addChild(cardLight); this is moved to main part of display list
maskedDisplayObject.x=cardLight.x;
maskedDisplayObject.y=cardLight.y;
// maskedDisplayObject.mask=cardMask; NO masking of this, you're only masking cardLight
cardLight.blendMode = BlendMode.SCREEN; // display mode is also changed
addChild(maskedDisplayObject);
addChild(cardLight);

how to connect a number variable to dynamic text in actionscript 3.0?

i know this might be simple but i have been searching everywhere for a fix but i just cannot find it!
i want to make something like a health #, so when you press whatever button the dynamic text # will go up or down. on my test project i have two layers, the first with the following code
var hp:Number = 100;
health.text = String hp;
hp being the variable, and health being the dynamic text. then i have the next layer with the button with:
function button(e:MouseEvent):void
{
hp -= 10;
}
without that second chunk of code, the dynamic text will appear, but once that is added it will disappear and the button is function-less.
how do i make this work??? once again sorry if this is a dumb question, i'm just very stumped.
The accepted answer is good, but I wanted to point out that your original code was actually very close to being correct, you just needed parenthesis:
health.text = String(hp);
For most objects String(object) and object.toString() has the same effect, except that object.toString() throws an error if object is null (which could be desirable or undesirable, depending on what you expect it to do).
This is not correct:
health.text = String hp;
use:
health.text = hp.toString();
and:
function button(e:MouseEvent):void
{
hp -= 10;
health.text = hp.toString();
}

How to perform font changes to a report using an option box

I am having issues trying to use an option box to change a font on a series of controls. Basically, I have a report (named Q_tblProject52Week) embedded in a form. I have embedded an option box within the form (called "cornice33) which aims to change the font on the two controls (testo107 and testo108) embedded in the report.
At the moment I am trying the following with no success:
If Cornice33 = 1 Then
testo107.FontName = "calibri"
testo108.FontName = "times"
ElseIf Cornice33 = 2 Then
testo107.FontName = "times"
testo108.FontName = "calibri"
End If
I am getting a missing object message (it is not recognising the controls testo107 and testo108). Also important to note, the report is embedded in a folder control.
You need to tell access that you refer to a control on the report which is a child of your form.
If Cornice33 = 1 Then
Me.Q_tblProject52Week.testo107.FontName = "calibri"
Me.Q_tblProject52Week.testo108.FontName = "times"
ElseIf Cornice33 = 2 Then
Me.Q_tblProject52Week.testo107.FontName = "times"
Me.Q_tblProject52Week.testo108.FontName = "calibri"
End If
hope this helps

Counter with "for" displaying on a dynamic textfield

im very new to as3 so i would appreciate any help.
Im trying to make a counter only using the command "for".
im counting on this from 1 to 1000 in steps of 20.
the next step i want to make is to display on the output tab
i already know i can make it with "trace();", but i also want this to be displayed on
the main .swf window, im trying using a dynamic text-field which i named "dyna"
The problem is that, it is only displaying the last number. "1000" or changing very fast that i barely notice, and the last one remains.
var i:int;
for (i = 1; i < 1001; i+=20)
{
trace(i);
//dyna is the name of my dynamic textfiled
dyna.text = i.toString();
//dinamico.text = String(i);
}
-Is there any way to record all the numbers on my dynamic textbox, something like [1,20,40,60,....] horizontally or vertically.
-Or maybe someway to run this from a button step by step.
like [click, 20; click, 40; click 60.....]
Thanks in advance
var i:int;
var str:String="1";
for (i = 20; i < 1001; i+=20)
{
str=str+","+i;
}
dyna.autoSize = TextFieldAutoSize.LEFT;
dyna.text=str;
Output
1,20,40,60,80,100,120,140,160...
Hope it helps
To run this from the button step by step you need a button, a listener attached to the button, a counter available to both button and text field, and a bit of code. The button has to be somewhere on the stage or in your asset, and named somehow, so you can address it by the name. Here it's named yourButton:
var counter:int=0;
yourButton.addEventListener(MouseEvent.CLICK,updateDyna);
function updateDyna(e:MouseEvent):void {
counter+=20;
if (counter>1000) counter=1000;
dyna.text=counter.toString();
}
Here you are, click - 20, click - 40, etc., up to 1000.
