Flex :: Print A Dynamically Created Component/chart That Is Not Being Displayed On The Screen?
Jan 24, 2011
I have a several chart components that I have created in Flex. Basically I have set up a special UI that allows the user to select which of these charts they want to print. When they press the print button each of the selected charts is created dynamically then added to a container. Then I send this container off to FlexPrintJob.
i.e.
private function prePrint():void
{
var printSelection:Box = new Box();
[Code]....
I have seen some examples on the adobe site that add the container to the application but don't include it in the layout. This looks like the way to go.
I have a custom component I've developed that's part of a dashboard.It does some polling based on a timer that's part of the component.
When the user navigates away from the view that contains this component I would like to stop the timer and hence stop the polling.I can obviously fire an event when the view's changed and catch it within the component but I was hoping that there might be a way to contain this all within the component.Is there an event or state change within a component that triggers and even when a component is currently be displayed?
I'm trying to build a Flash-based controller application to go on the web interface for the rack-mounted units which my current employer builds. The interface is defined in an XML file which is parsed and processed when the Flash application is started.
I've created some library symbols which act as various controls - sliders, toggle buttons, etc. I can add these fine to the stage. What I would like to do is group them together in a container of some sort so that I can show and hide them en masse without having to loop through all the controls. All library symbols I'm using are linked to ActionScript classes.
If I use a symbol I created earlier and added to the library as this container, everything works fine and the controls display correctly on the stage.
However, if I dynamically create a MovieClip and use that as the container, it never appears on the stage. The code is identical in both cases except for the class names being used. I am calling addChild() on the MovieClip instance to add the controls to the MovieClip, and then call addChild on the document class to add the MovieClip to the stage. As I mentioned above, this all works perfectly if I use a pre-created symbol from the library as the container.[code]...
I have problem with casting custom event currentTarget to component. When I'm trying to removeElement from its parent container i get error. What's the deal?
TypeError: Error #1034: Type Coercion failed: cannot convert mx.events::FlexEvent@8811c41 to com.modultek.pis.itemmachine.search.events.SortEvent. private function sortSelection_removeHandler(event:SortEvent):void { var sortSelection:SortSelection = event.currentTarget as SortSelection; this.removeElement(sortSelection); }
i created dynamically checkbox on data grid how do i find out Which checkbox select/unselect and which checkbox contact is select/unselect ? Because we cant set dynamic id for each checkbox
I have a java web application. When I log in to that application and navigate to a jsp which has flex chart embeded into it, the chart displayes just fine. I am using blaze ds remoting object mechanism. But when I want to navigate to a different page, it logs me out of application since the login session is lost.
I have data ItemRenderers with DataGroup, but I have many items, and it seems to me that DataGroup create all of them not only those few displayed on users screen, which takes time and resources.
I created a movie clip symbol with a user interface in it, using the standard components. It contains various components that I draged on the stage. I named the instances (e.g titleLabel). Then I created an ActionScript class for that user interface. Under the linkage properties of the symbol I specified that class. In the class itself, i declared the attribute "var titleLabel:Label". I thought this would be the same instance from the symbol? But: Trying to set the text of the Label AFTER the movie was dynamically added to the parent does not work. I cannot access any properties.
Here is the example:
My Class for the user interface:
Code: import mx.controls.*; class Information extends MovieClip { var titleLabel:Label; //this is the same instance name as in the symbol
How can I Create an animated Bar Chart or Line Chart type of component in flash programmatically, which should depends upon an incoming XML data, the chart should have the basic criteria like, Chart Label, Item Tooltips, background grids (without using any image). There also needs an ability to change the data which should reflect the chart as well.
My company have a web application product for distribution planning and scheduling. An important part of it is a gantt chart component where user can fine tune the schedules. Currently the gantt chart component is pure javascript+dhtml.I am currently looking into the possibility of moving to Flex to get richer interactivity and generally nicer UI.
The question is: is there any good interactive gantt chart component for Flex?By "interactive" I mean that user can interact with the gantt chart and modify data using it, as opposed to just seeing it as part of a reporting use case.
For my application I need a component (or combination of components) that shows a number of different types of events along a timeline, displays them in different ways as specified and allows you to click/hover along the timeline to add/modify/get details on events.
Basically I want a timeline across the top, always showing a 24hour period, but starting at variable points. I need to have different rows of variable height to display different types of data in different ways. for instance: row 1 will display the 'value' attribute as a circle whose diameter reflects value amount and change color based on a 'typecode' attribute. row 2 will display a line graph and plot chart based on different numbers (like one chart but with the datapoints as larger dots), and will also chart out trend of following or previous data if it exists. behind row 2 will display the same thing but for 5 previous days progressively more transparent
i'm building my first RIA in flex, and did a little of research to find a radar chart component free, but all i found is not free (licence >500$).Where can i find it for free ?
Flex: - Is it possible to export Chart/Graph/component with dataGrid data into xls file without using server side?
(Web Application)
I have gone through number of article but could not find any hind to do. As per few article it is possible to export data of dataGrid into xls by using as3xls-1.0.swc but not Chart.
I am looking to export data from dataGrid as well as Chart.
I am using FlashBuilder 4 and doing a simple application in flex. I am displaying a graph with 10 random values and based on the values I am trying to change the itemrenderer dynamically like CandlestickItemRenderer and BoxItemRenderer. Now my requirement was, if the values are > 10. I want to show my chart with CandlestickItemRenderer else i want to show the remaining spots as BoxItemRenderer. I am failing to do this. Either I am getting all the shapes as BoxItemRenderer or CandlestickItemRenderer. I am sending the code as a text file along with this.
I am having a set of slider for each bar in the graph. I have bindded all the sliders with their corresponding bars. When i change the value of slider the value in the ArrayCollection changes and i have also used
I'm new to Flex/AS3. I've attached an example line chart below. I want to know if this type of graph can be created using the standard line-series chart available in Flex (Flash Builder 4.6), or whether there's something drawn below that is non-standard and would therefore require some rather involved customization. The key features are:
-Different line styles and colors (dashed, dot-dash, solid, thick, thin, opacity) -Placement of units (y-axis "seconds" and x-axis "Hz") -x-axis zoom/pan control bar below graph (move knobs in and out to set x-axis min and max plotted values) -Log x-axis scale, linear y-axis scale -Data Tip (or, some call it tool tip, not shown below) -SI units for x- and y-axis tick labels.
My guess is that everything should be pretty standard to accomplish using Adobe's built-in charting (with the possible exception of item 6, see below). Is that a good assumption?I'm particularly concerned about the x- and y-axis tick labels (item 6). For example, the x-axis tick marks as a number would be:1, 10, 100, 1000, 10000, 100000, 1000000, 10000000 but they need to be replaced with SI units, where k=1000, and M=1000000, so the corresponding marks would be (replacing the numbers above with the strings below)"1", "10", "100", "1k", "10k", "1M", "10M".The same goes for the y-axis, where p represents 1e-12, and n represents 1e-9.I can create an algorithm that accepts a number and outputs a string to do the SI unit conversion. But given that, is there a way to easily manage the tick mark labels to replace the default numbers with such strings?
How can I make a action script controlled print screen that will save a part of a screen And can I filter a color out of it (so that only that one color will NOT be visible on the saved img) with AS

i want to know how can i run printscreen code from flash to capture user screen as i want to have flash presentation in 600x600px with disabled desktop and flash presentation should be in center of screen.
I'm dynamically creating movieclips with dynamically created movieclips inside them and am having trouble with targeting them.Below is a simplified example of what I'm trying to achieve, in the real file there are a lot more movieclips and I'm creating and naming them with a for loop.
This one is just one Sprite created inside another sprite. I can target the top level sprite named "testname". However when i try target the nested MC it throws an error.The bottom couple of traces are just test MCs I've made to make sure i got the syntax right, on targeting nested movieclips.
PHP Code:
var holder:Sprite = new test1();holder.name = "testname";this.addChild(holder);var holder2:Sprite = new test2();holder2.name = "testname2";holder.addChild(holder2);trace(getChildByName("testname").x); //this one traces finetrace(getChildByName("testname").getChildByName("testname2").x);//this throws up an errortrace(testclip1.x);trace(testclip1.testclip2.x);
I'm new to Flash Builder 4 and Actionscript 3 (actually, to programming as a whole beyond some very simplistic stuff). I have watched / read a bunch of tutorials, and started a project but now seem to have hit a wall. The answer is most likely simple, but seems to be alluding me.
How do I (or What approach should I take) to control visual elements, for instance, BorderContainer's, that I created dynamically?
As is, I have an Application containing a BorderContainer and a DataGrid. At runtime, 3 new BorderContainers (which are dragable, and resizeable) are created based on XML data that contains X & Y co-ordinates, and Height and Width values, and then added to the pre-existing BorderContainer. How would I go about getting the properties of these children BorderContainers to be displayed and remain up-to-date in the DataGrid (such as when they are moved/resized)?
I am dynamically creating panels based on information i get from an XML file but i'm having a problem with adding buttons to these panels. These buttoms are also created based on information taken from the XML file. The problem seems to be in the way i give the panels an Id name.[code]...
I'm trying to prevent a default chart item roll over highlight in a Spark column chart.If you look at any of the chart examples on this page , when you roll over any of the chart series items, they turn a darkened shade of their original colour. This is what I want to prevent.
So far I have had no luck with using the itemRollOverColor property, as this only allows you to set it to one specific colour for the whole chart (my app has several different coloured series on the chart at once). Also, trying to leverage the itemRollOver event (with preventDefault() etc) hasn't worked either.
I'm trying to make chart which is combination of bar and line chart using Flex Charting API . Here x axis would be common and y axis would be different. note that y axis got different range of value one is % and other is amount. Any one got idea how to make this chart. Here line chart would be staked on top of bar chart . The line chart and never over laid or drawn on top of bar chart.
I have some custom components, that derived from UIComponent. I overloaded the updateDisplayList so they have custom look. I've created a layouter that lays out these custom components, but to place them correctly, I have to know the custom componets width, height. They are created dynamically. After all of them created (creationCompleted event fired for every), i try to laying out them, but width/height property is still 0. I am also tried to add them to a canvas, before the layout process.
how to create custom UIComponent that placed dynamically, and get to know the width and height of it.
With the use of the mx_internal namespace I can set width and height (using the internal $width and $height fields), and it looks like it is working. But not so clean/good solution.
xml values are stored in 'arr' array collection. depending on the length of the array stored, the below described components are created and assign those values to relevant components dynamically. For Example:
I'm aware of PopUpManager and that custom modal windows can be created.But let's say I have a simple Canvas(or any component) and when I show it the background needs to be blurred out like how PopUpManager does when a new pop-up is shown.Is this possible?
