I have created an invisible button myButton_btn inside a moviclip with instance name supermarket_mc. The supermarket_mc is based on a class Supermarket, which has the following code and works fine.
public class Supermarket extends MovieClip
{
public function Supermarket()[code]....
Now, if I have a button on Stage they work fine when I add a listener to them. However, when I add a listener to myButton_btn ie:
supermarket_mc.myButton_btn .addEventListener(MouseEvent.CLICK, turn);
myButton_btn does not react to click events and I get an additional error Error #1009: Cannot access a property or method of a null object reference.I suspect that the MouseEvent.CLICK in the class definition overrides the MouseEvent.CLICK on the nested button.
Flex data grid has 1 default row created. When user clicks on the second row, a new row needs to be created and made editable.
Here is what works already - user tabs over the columns and when the user tabs while in the last column, a new row is created with default values.
Here is also what already works - user click a button outside the grid, which adds a new row.
(itemEditBegin and itemEditEnd have been implemented)
Here is what does NOT work: When I "single click" on the second row (no data yet - row is null), how do I detect that the currently clicked row is the second row and make it editable? Can I figure out the rowIndex from MouseEvent and use this to add a new row?
Find code below:
<mx:DataGrid id="myGrid" editable="true" click="clickEvent(event)"
itemEditEnd="endEdit(event)" itemEditBegin="beginEdit(event)" variableRowHeight="true" >

i have a datagrid which contained several items,when i click one row, a panel will show,however, if i have already selected one row and then click some blank place, this panel will also show because there is already a selecteditem,which will be a problem. Then i change this click event to change event, however, there will be another problem, which is if i click the same row, nothing will happend. so is there any better idea when i click a row, a panel shows and when i click the blank place, nothing happened.

View 1 Replieshow I can select a row in a datagrid in flex and have it highlight that row plus any related rows.Let me give you can example:Let's say that I have a datagrid. In the grid I have two columns for each row. One column has what type of car they own, and the other column has the owners name. Let's say that an owner has two cars. So you have a datagrid that looks like this (4 rows, 2 columns):if you click on the Camery row, the Jaguar row and the Camery row are both highlighted.I have a datagrid that has items, and has related items to its parent.

I know that datagrid can detect changes of single mouse click with
//add listener
myDataGridList.addEventListener(Event.CHANGE, myDataGridListChange);
public function myDataGridListChange(e:Event):void{
trace(myDataGridList.selectedItem.id);
}
but can they detect double mouse click?My purpose of doing this is that, if the user double click on a datagrid row, I need it to return me value of myDataGridList.selectedItem.id, so that I'm able to continue to proceed to the next stage of my game.

View 1 RepliesWhat is the event that gets fired when you click on a datagrid column to sort it? I could use that to know which column is getting sorted and hence have a common sortcomparefunction for all columns.

I need to modify the behaviour of an editable datagrid to this:
-Single-click on a row, doesn't make the cell show a text input field (only selects the row)
-Double-click on a row, doesn't make the cell show a text input field either
but
-Clicking a cell in an already selected row, shows a text input field ready to be edited.

I'd like to have a double click event on a datagrid in Flex3. The following example only works if the Accordion (id = "mustBeSecond") container comes after the DataGrid. Why is the order of the components important and what can I do to prevent this behavior? (The example does not work. If you change the order of "mustBeSecond" and gridReportConversions" the example works fine)

I have a loaded SWF into a simple "holder" empty movieclip I have on the root stage. Inside that SWF I have two variables that have "stage.stageHeight" and "stage.stageWidth" in them. If I leave them on the code and test the root movie I get this error: TypeError: Error #1009: Cannot access a property or method of a null object reference. So basically I can't seem to get the variables to get the parent stage.
