Flex :: Make Flex Grab The Focus Of The Mousewheel?
Aug 7, 2009
The entire box at the top is a Flex application. The box on the left with the list of pinball machines is a VBox. As you can see, if you try to scroll with your mousewheel, it doesnt respond. The reason this is shut off is because I found that if it's turned on, when you scroll up/down, the whole page goes with it. So if you scroll down four or five times, the application goes out of sight.I tried finding a solution to this when I programmed this last year but wasnt able to find any answers.if there's a way to make Flex grab the focus of the mousewheel and not let the browser move as well?

I created a custom component that is a s:SkinnableContainer. I want the background and other items to fade out when this component is visible. Something similar to what happens when calling Alert.show(..) so the Alert box is in focus and everything else is faded out.

I have a full screen flex application and I want the user to be able to scroll using browser scrollbars. I don't need mousewheel in the flex application and flex appears to block mousewheel events within itself. So mousewheel events do nothing.

I try to figure out how does focus mechanism work in Flex. Here comes the example of what I mean:Let's assume that we have a simple web application, which contains custom component that extends Canvas and implements mx.managers.IFocusManagerComponent. This component overrides focusInHandler and focusOutHandler methods and shows some feedback on how they are called (thinner or thicker border). This custom component also contains some Text.[code]
If you click once on a violet canvas it receives focus (focusInHandler is called), then if you click again the focus is lost (focusOutHandler called) - why?Of you click on a Text the Canvas receives focus (focusInHandler called) and keeps it when being clicked wherever on the area (focusOutHandler nevet called) - why?

I am creating a canvas in actionscript like :
private var cvs_preview:Canvas = null;
[Code]....
So on the focus change i want to run the "end_preview_on_focus_change()" but this is not working. As per my understanding, i think the canvas not getting any focus in the first place. I was trying to use focusManager.setFocus to do that after the canvas's creation complete. but even that is giving me an error.

I am trying to programmatically pass focus to a newly created TextField, but for some reason setSelection and setFocus do not work. For example, see my test code below:
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="vertical" creationComplete="_init()">
<mx:Button click="{tf.setSelection(1,2)}" />[code]....
The only setSelection that does anything is the 0,3 one on MOUSE_DOWN. I assume this all has something to do with the text field receiving focus with the mouse click,

I'm trying to set focus on a specific button when the app launches (or later based on certain events), so that the user can simply hit return to press the button. None of the following approaches work however.
protected function group1_creationCompleteHandler(event:FlexEvent):void
{
//btnBrowse.setFocus();
focusManager.setFocus(btnBrowse);
}

I have a custom component extends from skinnableContainer and only has two NumericSteppers.I explicitly set focus to my component like myComponent.setFocus(). It sets focus to first stepper which is correct, but when I press TAB to move focus to next stepper it moves focus to the next Component.
I set tabEnabled = true and tabChildren=true of the component, still no luck. How could I set focus to next stepper on pressing TAB?

In flex, I am using the following:
mx:TextInput mouseOver="tester(event)"
It works fine. My pointer goes over the textInput and it calls the function. But when I click inside the textInput to enter some text( focus is on the textInput) and then move the mouse (not taking mouse pointer outside of the boundary of textinput), the mouseover event is not trigerred.
If I use click event, then even if I am entering text ( or the focus is on the textinput) and then click, it will call the function.
How can I call the tester function on mouseover when the focus is on textInput?

My button doesn't have a blue focus ring around it, even though it has focus. I've got a component with a RadioButtonGroup and a Button. After a selection is made in the RadioButtonGroup, focus is switched to the Button. I added click="focusManager.setFocus(myCloseButton)" on the VBox.
After, a radioButton is selected, if the user clicks the spacebar the Button fires. So, as I understand it focus was switched to the button. But, the button doesn't get a blue focus ring surrounding it. How do I get the focus ring? I have visible="false". I turn them to visible, after some effects are finished. So, don't let that throw you.)

My app has a datagrid as well as many other UIComponents (buttons, menus, etc). I have a general stage KeyDown handler as well as a specific one for the datagrid. The behavior I'm trying to implement is turning out to be trickier than I thought: basically, when using the keyboard arrows I would like the datagrid to always hear about such commands, even if it's not in focus.
Possible approaches I thought of:have the DG be in focus at all times: seems stupid / tricky - basically would need to remember to give focus back to DG after any interaction with the rest of the UI, which obviously doesn't scale.try to set the DG in focus from stage KeyDown handler: seems like the timing doesn't work since the DG gets focus too late to "hear" the event.from the stage keydown handler, check if the DG is not in focus, and if so pass it the event. This seems to make sense in theory, but I'm not sure how to do this properly since my stage keyDown handler uses capture, and thus seems to catch the same event over and over.

I am using a combo-box as a Datagrid ItemEditor (Not just Renderer, my Renderer is a Label, double clicking on a cell makes the combo-box visible, as is the case with all item editors) Now, selecting one of the entries in the combo-box is no problem. But my problem is only when i select the "Fruit", which in turn pops open another layer called "Select Fruit" dialog
Questions: How do i keep item editor, while the focus is on the layer; right now as soon as i click on the fruit, my handler popsup the "Select Fruit" dialog and the focus is on the layer. Once the focus goes out of the editor, the ItemEditor goes away and ItemRenderer label comes back. I want to keep the ItemEditor alive! where do I hook up interms of events like begin/end ItemEdit etc?

I'm currently coding a Floorplan editor with Flex 4.I have a Floorplan Grid that extends the spark Group class. This Floorplan Grid will contain objects that extend the UIComponent class. I want the user to be able to select multiple objects on the Floorplan and be able for moving and resizing.
I'm just wondering if it's possible to have multiple objects being "focused" using the FocusManager, kind of like selecting multiple objects in Photoshop /Illustrator.

I've created something that works like a ToolTip in my Flex application. When I roll over a certain item renderer, I pop up a new control, position it, and remove it on roll out. The order of operations is like this:
Roll over event handler triggered. Add the tooltip to this.systemManager.topLevelSystemManager.toolTipChildren. On creation complete of my tooltip, set x, set y coordinates of the tooltip (on creation complete so the width and height are calculated since they are dynamic). Roll out event handler triggered. Remove tooltip.
This worked fine when I set the x and y coordinates to be x+10, y+10 from the current mouse position. I wanted to add something that re-positioned the tool-tip if it was going to be drawn partially off screen. I added a step that would calculate if it would be drawn off screen, and re-position the tooltip if it was going to be cut off.
The problem with my solution seems to be that it now runs in an infinite loop of redraws, since adding the tool-tip to the screen underneath the mouse triggers the "rollOut" on the item renderer. This triggers the removal of the tooltip, and starts the process over again from 1.
is there any way to ignore tooltip so it doesn't take the mouse focus away from the item renderer that is now under it?

I am trying to write the code for making a text input control in flex. As the user enters the value in text input control and then if he removes the typed characters to make the text input blank, then I print error message via StringValidator. But I want the focus to be set on that text input only until the user enters anything. How can I achieve that?

The behavior I'm trying to prevent is after a user clicks on a button, the button retains focus, and then if the user hits the space key, the button fires again. So I thought it could be solved either by setting the focus elsewhere, or by having the button ignore the space key. I've tried adding the following keyDown event listener on the button, but it didn't work.
private function btn_keyDown(event:KeyboardEvent):void {
// try to ignore spaces, i.e. don't click on SPACE when it has focus
if (event.keyCode == Keyboard.SPACE) {
}
}
I tried changing focus by doing the following, at the end of the function that's called when the button is clicked:
stage.focus = parent;

I found on Adobe website this cool as3 code to grab a sound and make a realtime waveform graph (I cannot post the link..The problem, to me, is that I cannot create in the same stage 2 graph from 2 input: the mic and an mp3.In my purpose, I'd like a stage with just 2 waveform graph. the upper one with the realtime voice from the mic input.the second one (just below the previous one) with a similar waveform graph but drawn by an MP3 file (or wav).
At the beginning I tried to use 2 inputs ".microphone" but I can always see just 1 graph. It's like the resources cannot be shared (al least not so simply).
