Flex :: Setting Properites Of Individual Columns In Grid Mxml Tag?
Feb 26, 2010Is it possible to control the properties of 'advancedgridcolumns' in 'advanceddatagrid' mxml tag. For e.g. suppose the grid data provider has 3 different fields. Out of these 3 fields, one field is 'to_be_decided'. This field should not be displayed initially. Only the remaining 2 columns should be displayed (visible true) and the third column (one with data field as 'to_be_decided', visible flag will be false here ) should be hidden. It will be visible when some event like a button click or something is fired.
We can do this in action script coding by accessing individual columns of grid and taking appropriate actions. But will it be possible to do so in mxml? Is there some default property in grid that can be used here ?In mxml I can not access them individually in the grid (under tag) and hence I can not set the visible attributes individually for each of them. To add them one by one in 'columns' tags I would be required to know the data field in array collection and that I dont know. Only data field known is 'to_be_decided', rest two fields will vary time to time. Therefore even if I addd this one gridcolumn in 'columns' tag what about the other two?
Something like this :
<mx:columns>
<mx:AdvancedDataGridColumns dataField='to_be_decided' visible=false>
<!-- How to add other 2 columns here ? -->
</mx:columns>

ActionScript 3.0 :: Error Accessing Property Of Loaded Swf?
Oct 11, 2010I am getting the following error when I importmy swf onto my main stage: TypeError: Error #1009: Cannot access a property or method of a null object reference.

On it's own the carousel works fine, it's only when I import it that it throws an error, all of the components within the carousel work fine (the images are highlighted on mouse over, the onclick code for the thumbs runs the right functions) it's just the scrolling that doesn't work.I've tried removing the references to stage from the loaded swf but I still get the same errors.I'm fairly new to flash but I'm finding the error messages to be fairly unhelpful at the best of times, I've attached the swf I'm trying to load in in a zip

1. I tried waiting for my attached movieclip to be added to my stage using the setTimeout method but no luck.

Jun 2, 2010Is it possible to set a percentage value for the width property of an UIComponent defined in MXML using data binding?
What I try to achieve is something like this (which doesn't work):
<s:Button width="{buttonWidth}%"/>
I know that using percentage for width or height properties in MXML is kind of a hack in the Flex SDK, since they're supposed to accept numerical values only, but since percentWidth and percentHeight aren't available in MXML, I'm pretty stuck =/
I would really like to avoid using code to do such a simple thing, in order to keep my code as clear and readable as posible.
Flex :: MXML Id Property Naming Conventions / Best Practices
Nov 3, 2010Since there's so much potential pollution within namespaces, particularly with the parser automatically declaring any MXML component with an id to be publicly-accessible using that ID I'm finding it dangerous to use just camelCase for MXML element ids. eg:
[Code]...
In Flash development, a lot of us did this for (automatically) declared stage instances like "mcMyTabBar" or "navMC" or "playPauseBTN". I'm looking for input from the Flex community about this. Am I just overthinking things? All of the related Style Guides and best practices documents I've read on the topic just say "use camelCase for ids, and make sure the id property is the first property". What's your take?
ActionScript 2.0 :: Accessing Grid Spaces In A Grid?
Jun 24, 2008I'm building a small editor that allows users to place electrical components onto a grid so that they can see how electricity works.

What I want the moviclips to do is to look in the four spaces either side of itself i.e. up, down,left and right.I have managed to pull the grid coordinates out of the grid which enables me to tell the clip which grid space to look at but have been unable to successfully get the code to work.Here is my code:
