Actionscript 3 :: AdvancedDataGrid : Conditionally Change The Icon Of The Leaf Node?
Mar 14, 2012
Introduction: I have a flat ArrayCollection of object's, which i group to create the dataProvider for an AdvancedDataGrid. In this AdvancedDataGrid i have different branches representing different type of tasks. I want to conditionally change the icon for the leaf nodes in the AdvancedDataGrid based on a date field stored in each object.For this purpose lets say each Task object contains an id and an updatedDate (Representing when the task was last updated). If the task has not been updated in the last five days (updatedDate+5 < today) the icon of that leaf node(Task) should be red, in constrast to the opposite the leaf icon in the AdvancedDatagrid should be green, e.g. like the image below. In this case task 35 has not been updated in the last 5 days, while 13 and 39 have.
Question: How do i change the leaf icons in the ADG based on the updatedDate of the underlying object? I would think that i have to extend AdvancedDataGrid and override some method, but which and how?I have seen easy ways of changing the open and closed icons on the web, but no way of conditionally changing an open node's icon :)
I have an AdvancedDataGrid tree with a ArrayCollection as its dataprovider. Now, for instance, i drag a leaf from one node to another node. To catch the event I'm adding a Listener to dragComplete.
[Code]...
My Problem: I want to know the new node where the leaf was dropped. Actually i would have expected that in the event there is a property like dropParent. This is not the case.
I have a tree being populated by an array collection. I don't have control of the data in the array collection and even when a node has no children it still has a "children" property that is causing my tree to treat every node as branch. I can do a simple check on the length of the array in the children property. If this is 0 I need the tree to display the node as a leaf, no disclosure icon. Any thoughts on how I can achieve this? It would be nice if there were a branchFunction like the iconFunction and labelFunction.
i gave the tree an ArrayCollection as dataprovider that i pulled from the database, and it contains the children, but the discloser icon wont disappear on an object that doesn't have a child.i think the problem is that the renderer doesn't recognize the leaf child, wich contains a children array of length 0, or null......
Is it possible to conditionally change the direction of a for loop in ActionScript? Example: for(if(condition){var x = 0; x<number; x++}else{var x=number; x>0; x--}){ //do something }
I'm having troubles expanding the root node of my AdvancedDataGrid. Simplified code below:
adg.addEventListener(FlexEvent.CREATION_COMPLETE, adgCreationHandler); private function adgCreationHandler(event.FlexEvent): void { adg.expandItem(groupCol.getRoot(), true) }
Does anyone have any thoughts on why this approach won't expand my root node, or another easy way of expanding the root node by default when the AdvancedDataGrid is loaded?
I have to designed a datagrid, in first column i have to use closed lock icon. when i click a row in a datagrid the selected rows' icon should change as opened lock icon. how i can achive this task in flex 3.
I want to add an indicator on a tree node icon , meaning , for example like in eclipse when there is an error the icon get a special small indicator on the regular icon. how can i do that?
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.
I'm having a really annoying problem styling the AdvancedDataGrid header text colors. With a regular DataGrid you can use a property called "headerStyleName" to set the color of the header text. According to the documentation this style is applicable to AdvancedDataGrid as well.Url..Here is a sample app that will show you what I'm talking about. Notice that both grids share the same style but only the normal grid will apply it.[code]
I have an advanced datagrid, but I want users to allow to copy some lines they want. when I use the property editable they are allowed to select the text they need, but they also are allowed to edit this. How can I prevent that?
I want users to be able to select any text in the datagrid, but they are not allowed to change the value of the grid. They should only be allowed to select and copy (ctrl + c).
I have created a flash movie(Interactive Map) for my company and I have been asked to print out the file with our company Icon instead of regular flash icon.
I'm trying to make an application in adobe air where you can externally load icons into the application. Can I change the window application icon in actionscript?
i have a other problem after i publish out to exe when you open the exe without fullscreen there is a title on top "adobe flash player" is there any way to remove the title? and any one have some good software that can change the exe icon?
I did a simple flash file to be able to users paint on draw. Now i want to change the icon only on certain zones but i don't know how to do that.. I want the icon to be the pencil when it's on the yellow area and i want it to be red again when it's on the red area.
I have below columnGroup in advancedDataGrid control and I want to show the header in red background color and also applied the style but the background color in the header does not show as red only the text color in the header is changed.[code]...
I have an AdvancedDataGrid with a custom label function whose value can change based on other form status (specifically, there's a drop down to choose the time display format for some columns).Right now, I have this labelFunction:
internal function formatColumnTime(item: Object, column: AdvancedDataGridColumn): String { var seconds: Number = item[column.dataField]; return timeFormat.selectedItem.labelFunction(seconds); }
[code]....
... and the timeFormat object is a combo box with items whose labelFunction attributes are formatTimeAsFractions and formatTimeAsInterval.The columns that have time formats have formatColumnTime as their labelFunction value, because extracting the seconds in that function and passing it in to the formatters made for a more testable app (IMHO).
when the timeFormat.selectedItem value changes, I want to force my grid to re-calculate the labels of these colums. What method must I call on it? invalidateProperties() didn't work, so that's out.
Until now, my solution for a disabled button's icon was to have a second, greyscale icon and swap the icons based on the button's enabled value. Obviously this is very hackish.
I'd like to drill down into the button's icon and apply some kind of greyscale filter when the button is disabled and remove the filter when the button is re-enabled. I tried a couple of things, but I don't know enough about Flash graphics to really have a good idea about what to do.
Can anyone give me some pointers? Ideally, I'd like a Flex 3 solution (since most of my apps are still mx/spark mixed), but Flex 4 would be OK too.
I adopted the tsunami effect that i've got from this link [URL] but the problem is how can i plug the title on each icon, showing up on an icon when i point on it (on rollOver)
I am new flash user and currently learning how to build dynamic webistes in flash , for this purpose i have loaded an xml file in my dynamic textfield and everything is working fine since i have used CDATA tag in my xml file , but when ever i try to change the font type with the help of xml , its simply not working .
The tree should have a minimum row count of 4 and a maximum of 10 (beyond which it should display the scroll bars). So, I have a tree with rowCount="4" and I want rowCount to change up to "10" depending on the currently expanded nodes. In debug I can see two of the tree's properties which I could use[code]...
But these are not accessible from outside so I can't find a way to understand if the tree is expanded or not.
