Feb 20, 2012

Is it possible to change the state of a mouse using actions script. So if the user clicks and holds down the left mouse button MOUSE_DOWN is it possible for actionscript to change the mouse state to MOUSE_UP without the user releasing the mouse?

I have a MouseEvent.MOUSE_DOWN

stage.addEventListener(MouseEvent.MOUSE_DOWN, start);

but in the start function I would like to set the mouse state to MOUSE_UP even if the user holds down on the button.

function start ():void {
trace("You have pressed the mouse button");
//SET MOUSE TO MOUSE_UP

Flex :: Click On AdvancedDataGrid Cell And Change Its Color?

Oct 9, 2010

simple (?) question: what's the easiest way to programmatically change the style of an ADG cell most recently clicked by the user? Important note: I'm assuming cells not to editable and the selection mode to be singleRow, i.e. the specific cell needs to render differently from the standard highlight that comes with being part of the selected line.

Actionscript :: Change The Style Of One Individual Cell In A Flex DataGrid?

Jun 13, 2011

I have a Flex DataGrid where one individual cell needs to be rendered in a different way from others. Specifically, for one row of the grid, one of its cells should be hidden.

The DataGridColumn is set out like this in my .mxml file:

[Code]...

but that doesn't work - in fact it messes up the display in a rather entertaining fashion (one of the other cells in the row gets an extra checkbox.. I suspect it may be possible by using a custom ItemRenderer class but that seems like a lot of code overhead for a fairly simple case.

Actionscript :: Flex - Run A Function When View State Is Change

Apr 12, 2012

I am learning Flex and trying to make a simple RPG to practice. I am using view states to change between screens. right now I have a HomeView.mxml which displays my character information, InventoryView.mxml which shows my inventory items, and EquipmentView.mxml which shows the equipped items. They each have their respective view states.

in my main mxml file, i create a global variable for the character and an ArrayCollection of items in the game. it creates 2 labels in mxml for Inventory and Equipment and when i click on the label it calls a click handler which sets currentState="EquipmentView" or "InventoryView" This works and the state changes and the respective views are shown properly. My problem is in my EquipmentView state. When i enter the state the first time, it has a creationComplete function which displays images for my equipment and sets a click handler. when i click the item, it "unequips" it and removes it from the equipment list and removes the image. this also works fine, but when I go to my inventory view and "equip" an item and return to the EquipmentView, the image does not show. I have a label which counts the length of my equipmentList variable and that is accurate when i switch views, but i cant get the image to display again. Is there a way to call my displayEquippedItems() function (which is originally called on creationComplete) when the view is changed?

Flex :: Why Does MouseOut Of A DataGroup ItemRenderer Cause A State Change

Oct 21, 2010

I've found a very annoying problem with the itemRenderers in a DataGroup in flex 4, when I mouseout of the itemRenderer is returns to its default state. Here's an example:

<s:Application
xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"
xmlns:mx="library://ns.adobe.com/flex/mx">

[code]....

When the user clicks on the button the VGroup is collapsed as expected, but then if a user moves their mouse out of the item renderer it then collapses, i.e. returns to its default state.

Actionscript 3 :: Flex: Content Not Rendering Correctly After Transitioned State Change?

Mar 1, 2012

I have a component with 2 states and I have added transitions for switching between the states, where 2 Move affects are applied to 2 different objects. This all works fine, however, after the transition from the first state to the second has completed the second state doesn not render correctly. It contains a TextInput control which is not visible, and a Button with a custom skin that is only sometimes visible and vanishes if you click on it. I have tried called invalidateDisplayList() and validateNow() after loading the second state but that has done nothing. I also have a VBox with a cornerRadius property set, strangely this does not seem to apply anymore and the corners are square, where they displayed correctly before I added the transition in.Here is the code for my states and their transitions:

<!-- different states of this component -->
<mx:states>
<s:State name="useForFree"[code].....

where the variables being set as masks are UIComponent instances where I have used their graphics property to draw a rectangle.
