• How to test the change of direction on the Simulator event?

  There is an example of change orientation Guide 0.92 development event.

  I add some codes for my application to deal with this event, but I don't know how to test it.

  I find that the return value of Accelerometer.isSupported on the device Simulator is true and simulator of funds, the value is false. But two of them cannot Simulator such an event.

  I know that you can test on IPhone simulator, use of change of direction "Command" + arrow keys.

• PartialTrigger does not trigger the onChange event of a InputText.

  Hello
  
  I have a problem with partial triggers. I have 1 inputText and commandButton 1 as below:
  
  "< tr:inputText id = value =" #{MyBean.locationString "input1"} "partialTriggers =" * testButton * "onchange =" alert (1); " "/ >
  "< tr:commandButton id =" "* testButton *" action = "#{MyBean.testAction}" partialSubmit = "true" / >
  
  If I enter inputText and manually change something, it triggers the onChange event. But if I change it with PPR, it does not raise.
  
  How can I trigger inputText onchange event OR how can I invoke a javascript function after the end of partialSubmit?...
  
  Thank you.

  Hello

  How can I trigger the inputText onchange event

  Set true to autosubmit property and as soon as you exit the field the value is submitted

  OR how can I invoke a javascript function after the end of partialSubmit?...

  Using the Trinity, you can call JavaScript from a managed bean. But for this, the PPR request to access a bean

• Prevent the change event in the DataGrid

  I have a datagrid that when an item is selected, the complete data for this item fill in a form where the user can change. I want to make sure if the user changes anything on the form, then click on another item in the datagrid control, caution gets up to let them know that they have changed the data and give them a chance to save it before they change something else.
  
  is this possible? I can keep track of when they change the data, and I can appear a warning when they change the selected line, but how can I prevent it from happening in the first place, until we give them a chance to save the data?
  
  Thank you.
  

  I can't think of a way to achieve that, preventDefault() method will not work because the change event cannot be cancelled.

  How about you, you disable the DataGrid control when the user changes an element? in this way, they will not be able to change the selection to what they save or cancel.

• How can I control the display of the lines in the datagrid control without changing the dataprovider?

  Hello

  I use advancedatagrid to make my table but I am facing a problem to jump a few lines that are unwanted or to hide. I should keep my dataprovider of origin without modification to achieve this behavior as I use it in many places.

  Can you guys please send me a tip or the sample code? I appreciate a lot to her.

  Thank you

  Siva.

  Don't know what property, you must use advanced data grid or if it is available.

  But you can make use of function filterFunction filter your original dataprovider and the user, the value of return as the dataprovider of the ADG.

• How can we change an image programmatically in the DataGrid cell

  I have a DataGrid that contains a status icon. I was able to get the initial to display in the DataGrid control status icon. But I'm unable to update the computer. Basically, I need to update the image of a selected line with a "assets/processing.png", ' assets/success.png' or ' assets/failure.png' image. I can't seem to be able to find a way to access the image in the cell need to update/replace it. I tried to give him a property from my collection ArrayCollection data provider, but it does not work. I also tried some how to get a reference to the original image, so it can be replaced, but can not understand how to do such. Here is the code for my DataGrid. I'll be very grateful for any help in this. (I'm relatively new on Flex/ActionScript, but a developer experienced otherwise).

  <mx:DataGrid id="myDataGrid" left="0" top="0" bottom="0" right="0"
                       allowMultipleSelection="true" verticalScrollPolicy="on"
                       draggableColumns="false" resizableColumns="false" sortableColumns="false"
                       dataProvider="{myArrayCollection}">
              <mx:columns>
                  <mx:DataGridColumn headerText="Name" dataField="name" wordWrap="true" />
                  <mx:DataGridColumn headerText="Status" dataField="status" width="75" textAlign="center">
                      <mx:itemRenderer>
                          <mx:Component id="statusComponent">
                              <mx:HBox id="imageBox" width="100%" height="100%" horizontalAlign="center">
                                  <mx:Image id="statusImage" source="@Embed('assets/pending.png')" width="16" height="16"  />
                              </mx:HBox>
                          </mx:Component>
                      </mx:itemRenderer>
                  </mx:DataGridColumn>
              </mx:columns>
          </mx:DataGrid>
  

  The image must be a property of the arrayCollection collection.  You can either save the image url as a property of type string, or if you must nest, then you can create an actionscript for each image object in a script (private var image1:Image = Image(); image1.source=@embed...)

  Then, in the code that processes the event that causes the image must change, replace the image property of the collection arrayCollection member (s) concerned. Then, at the end of the code for the event, trigger the DataGrid to update using the method myDataGrid.invalidateList ();

• Is it too late to change the preview thumbnails, once the beforeSave event?

  My goal:

  I need to display nonprinting layers in the preview thumbnails of my .indd files. We produce print jobs that will post processing applied to them (thermography and cutouts glued on the printed cardstock). Our .indd files have layers containing images of these post production so that we can determine the alignment and spacing for the final product.

  Here are the graphics are placed in the nonprinting layers so that they do not print. However, InDesign generates the preview thumbnails that do not contain these nonprinting images. It is a problem for us because we can't tell the difference nuanced between soley by their similar indd files preview images.

  My goal is to register somehow these nonprinting layers in the image preview thumbnail.

  What I've done so far:

  I have a startup script which records for the beforeSave and afterSave events. Before that the same it marks all layers not printable are printable (printable property = true). AfterSave event then this cancels by defining these layers to unprintable. I followed what layer was initially not printable adding a moniker the layer name.

  What does not work:

  When I run a script which marks the layers as printable records, then cancels printable changes everything works perfectly. The thumbnail preview is exactly what I want.

  However, when I run as a startup for events script beforeSave/afterSave. this fails:

  • Success: The beforeSave correctly updates the print property, then changes the name of the layer. This is as expected and work well.
  • Success: the afterSave properly resets the property printable and changed the name of the layer. This is as expected and work well.
  • Failed: Thumbnail preview of the file reflects not the printable = real peroperty of affected layers.

  My Question:

  From what I saw above it seems that the preview image is determined before the beforeSave event fires.

  Question 1: Is it true?

  Question 2: How can I assign printable layers properties whenever there is a backup?

  Last resort I could intercept any sequence of keys CTRL + S or the file-> Save menu option and call my original script (as described above). I would avoid this because it is fragile and less elegant.

  Follow the question: can anyone show me what is real workflows for these events? For example what InDesign is then his backup work and at what points it fires events beforeSave and afterSave?

  Follow-up:

  I think I solved the problem. Wow, Adobe, you could do better than that.

  My solution is during the event "beforeSave", create a new textframe object. Fill it with text empty of meaning. Position somewhere predominently on the first page where it will be visible. Then remove the textframe.

  This is apparently enough to ID to render the thumbnail overview. So my entire solution:

  • In a beforeSave event
    • change my "unprintable" layers to print.
    • Then, create textframe, add text, place it in the middle of the page, and then remove it
  • AfterSave event
    • change diapers updated back to "unprintable".

  As stupid and hacky because it seems to me, it seems to work on ID CS6 for Windows.

• Change the first column seen in the datagrid by code?

  Hello

  Is anyway to change the first column in a DataGrid using action script? I mean, for example, think I have 10 columns, only 3 are seen (0,1,2). I just want to have a button to change the first column view. Thus, for example, if I press it, 1.2, and third column will be those that is displayed in the datagrid control. I need to emulate the same thing that the scroll bar when you drag in a datagrid, but instead of letting the scroll bar does that automatically, I want to "scroll" datagrid manually.

  Moreover, is anyway through datagrid children and hide the scrollbar manually?

  Thanks in advance,

  Aron.

• No response from the DoubleClick on a DataGrid event

  I have a DataGrid, where I put the doubleClick action to initiate an openWindow function, but when I compile and run the application, it seems to ignore the event. I tried to adjust the action to click to activate this function, and it works exactly as expected. According to the docs, DataGrid supports the doubleClick event, so I don't know what the problem is. Anyone else seen this behavior, or else can someone confirm that doubleClick works on DataGrids?

  Define doubleClickEnabled = "true".

• button in the datagrid not pulling cell click event

  I have a datagrid with a custom button built in Actionscript rendering engine. I'm trying to figure out how to capture the click event of the component when the button is clicked.
  
  I am generating the component of the cell based on the field type:
  column.itemRenderer = new ClassFactory (DpFileRenderer);
  
  The element itself:
  
  package joe.ui {}

  import flash.events.MouseEvent;
  import flash.events.Event;
  
  SerializableAttribute public class DpFileRenderer extends button
  {
  [Embed("/assets/icons/drive_disk.png")]
  private var diskIcon: Class;
  [Embed("/assets/icons/drive_disk_grey.png")]
  private var diskIconDisabled: Class;
  
  override the updateDisplayList(unscaledWidth:Number,_unscaledHeight:Number):void function
  {
  super.updateDisplayList (unscaledWidth, unscaledHeight);
  This.label = this.listData.label;
  If (this.listData.label! = '0')

  This.Enabled = false;
  }
  this.labelPlacement = 'left ';
  this.setStyle ("color", 0x000000);
  }
  }
  }
  
  I don't know exactly on where to put a diffuse in this event.
  
  Could someone help?
  
  Thank you.

  Add an event listener in the constructor of your rendering engine and dispatches the event from the Manager. You certainly want the event to bubble as well.

  Here's an example, using a text control, but the theory is the same.

  DOH! I thought I was in the flex forum so ignore my previous answer.

  You must set the dataProvider on the dg after completing the dataprovider with data so spend aDg.dataProvider = new DataProvider (myDp); at the end of the dataOnLoad method
