let npapi windowed plugin droppable - qt

I create a windowed npapi plugin on windows, and expect when dragging a file over the plugin, the cursor shows the
accepting drop effect.
For the aim, I tried the following two methods, which both work well in native window app.
call DragAcceptFiles(hwn, TRUE) for the npapi plugin's native window handler
create a IDropTarget class for the handler
But both show forbidden drop cursor. Any idea?
A plus, the program's architecture is Qt embedding CEF.

#Georg Fritzsche and #taxilian give the answer, add a child window to the windowed npapi plugin.
And do drag and drop in the child window.
In my project, I use another solution, described below.
Provide a drag move api in windowed npapi plugin.
This native api handles mouse over test, cursor set, fire custom event so etc.
When drag and drop started, trigger a timer in javascript end to call the api.

Gesture Events and StageWebView

Greetings! I have a Flex 4.5 Mobile project rolling, and I've hit a pretty crazy snag. I'm using a StageWebView object to render web pages, embedded within the rest of my spark layouts. I'm trying to add a gesture event to the component that contains the StageWebView, but since the StageWebView object doesn't belong to the Flex stack (it inherits from EventDispatcher, not UIComponent) all of my events seem to be getting eaten. Any mouse based event (click, gesture, etc) doesn't seem to register, and I'm not sure how to get around it. The gesture events work if I use the area where the browser is not rendered. How can I get the gesture event from the outer SkinnableContainer?

Thanks!
I guess you might have to wire up the gesture events yourself, just doing a quick digging in UIComponent.as, it has these:
[Event(name="touchInteractionStarting", type="mx.events.TouchInteractionEvent")]
[Event(name="touchInteractionStart", type="mx.events.TouchInteractionEvent")]
[Event(name="touchInteractionEnd", type="mx.events.TouchInteractionEvent")]
it's not a bug, from what i understand any mouse interaction over a stagewebview means an interaction with the html currently loaded in itself. you should capture events there and trigger it back to the swf.
surely there are some jquery plugins or something that have gestures to help achieving that.
it's a bit of a bummer that you cant overlay stuff over them though.

Straightforward way to count number of windows up through PopUpManager?

I'm using the PopUpManager to bring a bunch of event windows up.
I want to make it so that only one window can be open at a time, but I don't see anywhere in the code that tracks open windows to set up a conditional. I guess it just creates the windows and then sets them free?
Thinking about a windowCount variable that increments when I add a window and decrements when I remove one, but since the PopupManager is called in different classes I'd have to start throwing events all over the place. I can do that, but I'm wondering if there's a more straightforward method?
The systemManager (rather than PopUpManager, go figure...) provides information on the currently opened popup windows.
If your popups are all model then you will be interested in 'systemManager.numModalWindows':
The number of modal windows. Modal
windows don't allow clicking in
another windows which would normally
activate the FocusManager in that
window. The PopUpManager modifies this
count as it creates and destroys modal
windows.
Otherwise try out 'systemManager.popUpChildren':
An list of the topMost (popup) windows
being parented by this ISystemManager.
An ISystemManager has various types of
children, such as the Application,
popups, tooltips, and custom cursors.
You can access the top-most windows
through the popUpChildren property.
The IChildList object has methods like
getChildAt() and properties like
numChildren. For example,
popUpChildren.numChildren gives the
number of topmost windows and you can
access them as
popUpChildren.getChildAt(i).
I see a few options:
1) Make all your windows modal; so that the application can't be used until the window is closed. This is a argument to the createPopUp method on the PopUpManager. Presumably you do not have Popups creating other popups.
2) Create your own Manager class, possibly an extension of the PopUpManager class that keeps track of all open windows. Then you'd have a single source of all PopUps and could maintain them that way.

Bring a window to the front in Maemo

I've got a Maemo (Qt) app that does some integration with the built-in media player via D-Bus. All the control functionality I need is complete, but I've got a requirement to show my application window (which gets backgrounded when playback starts) instead of the media player when the playback window is closed (it's a stacked window).
It should go like this: user clicks item in my Qt application, which launches the media file in the native media player. User watches media file, exits by clicking the arrow on the playback window. I'd like to somehow catch this event and bring my application to the front instead of showing the media player's main window.
Is it even possible on Maemo? I'm thinking that some low-level X coding might be required.
Answer was painfully obvious, I can catch a state_changed signal from D-Bus- state=0 when the window is closed.
You can also use the raise() method of Qt windows.

Application.application.nativeWindow.activate() problem on Windows

I have an AIR application with a system tray icon. When clicked it shows and activates the app. This is working as expected when the app is hidden (docked), however if I select another application so my app is in the background clicking on the system tray icon does nothing.
Oddly I also have a contextual menu on the system tray icon, which has an option to restore, this calls the same event handler as ScreenMouseEvent.CLICK, yet works.
I expect it's something to do with the contextual menu changing the focus, perhaps it's a bug in how AIR works with the system tray, perhaps it's just something I'm missing. Would be good to know if that's the case.
Thanks in advance

//instead of just calling
activate();
//call
nativeApplication.activate()
//or even better
nativeApplication.activate(nativeWindow);
Update based on OP's input: if you have multiple windows open for the application, use:
nativeApplication.activate(nativeApplication.openedWindows[0]);
If you are not in the main WindowedApplication class, you can use the static property NativeApplication.nativeApplication to get a reference to the singleton object.
WindowedApplication.activate()
Activates the underlying NativeWindow (even if this application is not the active one).
NativeApplication.activate(window:NativeWindow = null)
Activates this application. If the operating system allows activation, then the specified window is activated and brought to the desktop foreground; that is, in front of the windows of other applications. (If the window parameter is null, then a visible window of this application is activated.)
livedocs is not clear on why this is happening. It says activate() activates the underlying native window - one would expect it to be brought to the front when it is activated, but that's not happening.

How do I create a popup from Flex without a browser toolbar?

I'm trying to launch a popup window from Flex, but the popup window needs to have certain properties as one can usually specify with the JavaScript window.open. For example, the popup window should not have a browser toolbar or URL box.
I've tried using navigateToURL, which works fine, but I can't find a way to specify the popup window properties.
I've tried using ExternalInterface.call, but the popup gets blocked when calling window.open directly, or even creating a custom JS function that calls window.open.
Help!
Thanks!
I don't think it's even possible to disable the browser toolbar or URL box in a lot of browsers (I certainly do not allow it on any of the browsers I use).
If you're using navigateToURL, why can't the page you're opening run the JS to try to disable the toolbar and URL? I think you can also attach attributes to the URL if you wanted to send properties over.
You can use PopUpManager class of Flex for creating custom pop up box.
This example may help you. Custom PopUp
Check out AndrewT's blog about checking for popup blockers.
If not blocked, then use ExternalInterface; otherwise use the flex popup.
Detecting Popup Blockers
Or better yet, use SWFAddress v2.3 (javascript and AS3) modules. The AS3 has SWFAddress::popup() facade that proxies the poup call to the javascript. You can modify the SWFAdress.js popup function to use Andrew's logic and return a status. This would be a best practice: leveraging superlative SWFAddress library from flex for deeplinking, google analytics, and popups.
