Flex :: Separate Objects Into Two Datagrids Based On Specific Value
Oct 5, 2011
Im using Oracle, BlazeDS, Java and Flex. I have a list of objects displayed in a datagrid(Lets call them Main-objects. Each of these objects have a set of UserComment-objects associated with them(One-to-Many relation in the DB). These comments may come from two different "types" of users, distuingished with either a 1 or 0 in the UserComment-object's "userType" field. Each time the user selects a Main-object in the datagrid, the UserComment's related to this object is displayed in a separate datagrid below.Based on the introduction, i want to separate the UserComment's into two separate datagrids (one for each user-type), instead of the one i have now. So my question is: What is the best approach for performing this task? What is the best way of separating the UserComment's into two separate data grids based on the value of the "userType" field?
how to compare values of two separate datagrids.for example lets say i have a datagrid named mg_dg like this:
PHP Code:
[code]...
this is sorta what i'd like to accomplish but not in the sense of using a textinput component.it filters the datagrid of the text typed into the textinput component.
I am using Flex to create a small form. All I have at the moment is a List component, that I want to populate with a list of font names.I am getting the fonts using Font.enumerateFonts(true);. This returns an array of flash.text.Font objects.
The Font objects have a fontName property that is a String of that fonts name.My problem is that I can't figure out how to bind the List's dataProvider to the fontName property of each of the Font objects in the Array.Is there a way to do this just with binding? and not creating a new array of Strings by looping through the Font objects?
Canvas.addChild() insists any DisplayObject added implements IUIComponent. But I don't want my core graphics engine dependent on Flex. Is there an obvious/common way around this, to have simple graphical objects like Sprites & Shapes in a Flex application? The individual DisplayObject children I want to add as children represent objects in a game world, like a spaceship or a missile or a horse...
Not sure if Canvas is the most appropriate container, perhaps Group or another class is optimal for a game-engine... example MXML & AS3 code showing a skeleton setup is most welcome. I'm targeting Flex4 & Flash 10, but Flex3/Flash9 solutions are still of interest.
I've got a Grid whose GridItems contain another DataGrids. (The DataGrid are nested in the Grid). Now I changed the Grid's horizontalGap-StyleProperty to zero. But because there are several DataGrids in one GridItem, there is still about 5-10px spacing in between those DataGrids. How to get rid of these spacings ?
I have a DataGrid which contains a DataGridColumn with a textinput and DataGridColumn with a Button.The DataGrid is bound to some XML which displays values in the text box.When the button for a row is clicked I need to get the value out of the text box and save it into the relevant XML node.My solution was just to pass the id of the row to the button click event then loop over the rows until I find the id then just grab the text box value. Simple. However the only advice I can find on looping over the rows is via the underlying dataProvider, which is nonsense as the two aren't the same thing.
we want to drag a button with a css layout from one grid to the other. On the second grid should be the same button with this layout. The grids are in different mxml files.
I have 2 advanced data grids, one above the other. They both have the exact number of columns, and pertain to each other in the same way. But each is showing different data, which is why I split into 2 grids. However, on each one you can resize the columns, what I would like is to make it so that if you resize a column on either datagrid the same column on the opposite datagrid resizes as well, so they are both always lined up.
I want to use one data source (e.g. an Array) for multiple Datagrids that have different filterFunctions attached and show different columns.First, I thought I use a very straight forward apporach:create the Arraycreate an ArrayCollection for every DataGrid and set the "source" property to the Arraycreate the DataGrids and set their dataProvider property to its designated ArrayCollectionSo now. every ArrayCollection can have its own filterFunction, sort state etc. but there needs tos are dispatched and I have to call itemUpdated manually on each of the ArrayCollections. While debugging into the code in order to get a deeper understanding for Flex, I tried to figure out, what this misterious "itemUpdated" method does, especially as it notes in the adobe documentation, that, if no "property" is given (e.g. it is null), a simple "refresh()" will occur.
I did not find any calls to "refresh()" in the whole debugging (and I went down the framework whole as deep as possible (btw: lots of funny comments right in the code :-) )he only thing I could find was a CollectionChangeEvent getting dispatched with a PropertyChangeEvent in its "item" property. Which was of the kind "UPDATE" (and not, as I would expect "ADD"). When trying to dispatch that event manually, it never worked (e.g. the datagrid did not update).
I have multiple datagrids with about 10-15 columns total. I have a numeric sortCompareFunction for each column. At the moment, I have a separate function for each sort compare I do....each does the sorting numerically. I'm guessing I could condense functions sort1, sort2, sort3, etc into 1 function but I can't figure out how:
private function sort1(obj1:Object, obj2:Object):int{ var value1:Number=(obj1.zip==''||obj1.zip==null)?null:new Number(obj1.zip); var value2:Number=(obj2.zip==''||obj2.zip==null)?null:new Number(obj2.zip);[code]...............
I've got a client who has a list of items on a Datagrid. When the row is clicked, it sends the user to another page with details of that item. The client wants the rows to act like HTML links, where the color is purple when the link has been previously visited and its normal color if the row hasn't been clicked in the past. I've accomplished this with item renderers and SharedObjects. The application loads the visited ids into an array on start and the item renderer colors the individual cells if that row had been visited.
The issue here is that the client also wants the text color in the rows to turn white when the user rolls over the row. Because the item renderer sets the color, it doesn't respond to the default stylesheet for the datagrid. I can make it turn white on rollover of an individual cell, but we need the whole row to do it. Is there a way to trigger a function in all the item renderers in the row, or is there a better way to accomplish this?
I have a flex application in which I have a TabNavigator with multiple tabs and a datagrid in each of those tabs. I have bound s single array of data to each grid.
What I want to do is to bind each grid with a particular set of data in that array i.e. to distribute array contents among grids based on data type. For example items starting with letter A could be displayed in first grid, B in second, starting with C in third and so on. Hence you can say alphabetically distribute the data on different grids. The problem is that the data will be added randomly by the user.
To make one data array for each grid is not an option (due to design restrictions).
Is it just me, or do flex MX datagrids sort in a case sensitive manner be default? That is, they'll sort like this:
I know I can give a datagrid column a custom sort function, but do I really have to do that for every column in the app?
So this is a bug in a legacy app- updating every single grid to spark really isn't an option (if that's even a fix). Am I missing some obvious way to change the sorting pattern for an entire grid?
we have developed a web application by using flex-blazeDS-Java. Now we got a requirement that to print the user existed page whenever he clicks on Print button. I am able to print my flex componets and advanced datagrid but not able to print the custom item renderer images which are rendered in datagrid. And also how to print the multiple pages when I have large data in advanced datagrid.
This loads a new movie clip of a simple slideshow which has 7 frames. You can click through these frames with left and right buttons.
I no longer need the left and right buttons. I need a group of 7 buttons sitting under the "Recent Projects" link which each link to a different frame of the recentProjectsBody_mc movie clip.
I assume I need to load this movie clip before I link to a frame within it. But then how do I link to a specific frame within that movie clip?
I have a movie clip within file A.fla. This movie has buttons. Each of the buttons should go to their respective frame within a movie clip from a separate file.
I'm practically new to flash and action script and i'm currently trying to code something. I have a *.fla file with a dynamic text..I created a separate *.as file for the action script. My question is how can i reference the dynamic text properties? for example if i put the following code on my *.as file dynamic_txt.text = "place your text here" this will produce 1120: Access of undefined property dynamic_txt..How can i reference the dynamic text on my *.fla from my *.as?
I need to figure out how to print out 2 different objects on a separate sheet of paper with only 1 print button, a PRINT ALL button.Here is what I thought would work but not working, please help:
I need to have the ability to go to a specific frame in a timeline based on what the web address is. I basically want to play an intro for my index page only and skip to frame 30 for all other pages. Example [URL]
I have a text box which when submitted will action a specific task depending on what its contents is, so for example, you type "one" in and it will bring up a picture of a boat where as if you type in "two" and press enter it will bring up a picture of a car. Now thats all working fine, what I have an issue with though is that with several of the tasks I want it to open the same window but load different content within that window depending on what word was typed.
So if you type "one" it will load a grey window and load within that a picture of a boat, but if you type "two" it will load the same window but load a picture of a car inside it. Now the way i can see this working is when you submit the box it sets a variable and when the window loads, depending on what that variable is set to it will load the relevant info.
[code].....
I have also tried placing that last bit of code within "window" instead of "winbod" but it still doesn't work. I'm pretty new to variables so I know it will be to do with me not placing them right. Where abouts am i going wrong here?
I am trying to make a light comparison chart where the lights can be turned on inividually by the user and one can be compared to another depending on which of the 6 lights you want to view.So far i have managed to make this work with 5 lights over 33 layers and diffferent buttons and different handlers for each of the buttons on each layer but as soon as the 4 and 5 light come into play everything slows down struggles and sometimes gives up.Is there a simple way of doing this which i am unaware of.I am currently using the gotoandstop comand to go to a specific frame based on the button press.
I was thinking that it may be possible to create a primitive, yet usable actionscript based text to speech system for Flash movies (One that is platform independent).
Is it possible to right a series of actionscript commands that would play a collection of certain sound files based on what word or words the user has entered?
For example:
If the user types "Red Pen"
Can actionscript tear apart those two words and play sound files "Arr", "ee", "Dee", "Pee", "ee" and "EN"?
If it is possible, and if someone could help me out on it, then I'll start figuring out what phonetic sounds I'll need to record and program, and see if I can't build a simple text to speech program for flash movies.I have no immediate commercial application for it, and I don't plan on one.So if I can pull it off it'll be free to everyone, source code and all. Of course, it may be in my voice, but it shouldn't be hard to take what I plan to do and use it as a template for anyone else's voice recordings.
im currently writing a piece of code where i need to get all children that are specific class or extend one.
currently im using this
ActionScript Code: public function getConnections():Vector.<NodeConnection>{ var res:Vector.<NodeConnection> = new Vector.<NodeConnection>();
[Code].....
The problem with this is that 1st, string comparison is slow, and im expecting that there will be hundreds, of instances on stage. and secondly, It is very probable that i will extend the classes that i use in the functions, so their toString() will produce different name. e.g if i have on stage instances of "Node, ExtendedNode1, ExtendedNode2 " since they are all nodes, id like to all of them be returned.
I have airplanes that are flying past the screen from a top down view. when the air planes crash, I scale them down to make it appear as if they are falling closer to the ground and farther away from the screen. I have turrets on these crafts as well. they are seperate objects from the air plan. I scale them down as well. The only problem is they dont reposition correctly. they stay in their x and y positions even though they are being scaled it looks as if they are being pulled away from the air plane. is it possible to reposition them correctly based on the size on the object they sit on (i.e. the air planes)
How can you call objects based on properties they have instead of object names? For example if i want all the objects in an area to move somewhere else. Thats not what im trying to do but just an example. Also im using flash mx 2004
I have editable grids which are 2-way binded to my model. What I want is to validate my data when user edits any cell before it get updated in model. I have applied my validation at ItemEditEnd handler, but, I want to apply validation in between itemEditBegin and itemEditEnd events.
