How to add context menu Xamarin.forms

I would like to create context menu in my project. On android it's called PopupMenu. On click of button, I have to show the popup with 3 rows and it's clickable event. How I can implement this in my code? Example of this menu here:
http://www.javatpoint.com/images/androidimages/popup2.png
The Xamarin.Forms way to handle this is to call DisplayActionSheet() on the Page.
It's not exactly a popup, but on the other hand it has better chances to be fully displayed and visible on screen if your view can scroll.

Providing help for a modal dialog in Qt

I am working on a Qt application and developing a context sensitive help solution. When a Modal Dialog is active and F1 is pressed, I would desire to be able to interact with the Modal Dialog and help at the same time until the help solution is no longer needed. If I make the Modal Dialog Non-Modal with the F1 event, this allows the parent window to be manipulated which defeats the purpose of making it Modal to begin with.
Does someone have a good solution that allows a user to interact with Help and a Modal Dialog that is better than simply swapping Modality between the Modal Dialog and the Help Dialog? (This is done by setting the Help Dialog property to Qt::ApplicationModal, then when Help Dialog is closed, the Modal behavior returns to the previous Modal Dialog)
Thanks in advance.
You could just use an external help viewer which runs as a different process. If the number of parent dialogs change or the relationship, the developer needs to go back and fix all the windows intended to be non-active.

MS Windows- Main window no response when show menu on a tray notify icon(use a hidden window to process message)

I implemented an class, this class will show an tray icon. to handle the message from the icon, I have to create a hidden window.
Eevery thing works fine, except if You click outside of the icon, icon will not disappear. I have fixed this by adding code below:
SetForegroundWindow(message-only-hiden-window) // added
TrackPopupMenu()
RESOLUTION:To correct the first behavior, you need to make the current window the foreground window before calling TrackPopupMenu or TrackPopupMenuEx.
Now I get the expect result: the menu can disappear if you click outside of the tray icon.
The problem is now, after the call of SetForegroundWindow(message-only-hiden-window) the main app window will no responding(cannot resize move) I can see the main window actually get those messages in spy++.
Keep this the mind if no call on SetForegroundWindow(message-only-hiden-window). Fine. Except the menu will not disappear.
Anyone has experience on similar situation?
How do you implement an tray icon which has no foreground window at all?
Any kind of help will be appreciated. If you wanna the source code I can email you.
resolved. I have forgot return DefWindowProc in the message only window. tricky

Flex Accessiblity - Tab Focus goes out of flex app

In an accessible flex app, the user can navigate through the control by using the TAB key.
The flex app pops up on top of the html page aftert the user activate a particular link, and is loaded using swfobject.embedSWF.
It works well in most cases, but there are some instances where either or both these happen:
a) The flex app loads ok, the "flex focus" is set on the intro text label to read out loud, but pressing tab seems to still cycle through the links on the page behind. (Now Fixed, see Edit 2)
b) The focus worked well and pressing tab cycle through the controls ok, but after going through them it then tabs out of the flex app and onto the address bar.. it becomes a nightmare to even try to get back to the flex app without clicking on it.. which isn't exactly accessibility friendly.
Is there any way to prevent these from happening?
EDIT: The target browser is IE. Seems to be the most used with Jaws
EDIT: I managed to fix problem (a). The trick was to call focus on the swf object, but after a slight time out - must be something to do with flash/js ready state.
setTimeout(function(){
document.getElementById('swfobject').focus()
},25);
Problem (b) is still an issue though...
In your mx:Application component, add an event listener for the keyFocusChange and add this code :
protected function application1_keyFocusChangeHandler(event:FocusEvent):void
{
event.preventDefault();
focusManager.getNextFocusManagerComponent(event.shiftKey).setFocus();
}
b) Try to place some focusable element after swf in html. When focus leaves flex app, see if onfocus handler of that element gets called. If it is, you can refocus flex app from there or redirect it where you want.

navigateToURL ... set modal property

When a user clicks a button, I need a separate browser window to popup. How can I set the modal property of the application? (ie, when a popup window opens, the main application is disabled until that popup is closed ... I need to use a browser window rather than a popup window, but can't figure out how to disable the main application)
PopUpManager.createPopUp (this, navigateToURL( url, "http://www.google.com" ) , true );
thanks!

Ok, my modal dialog looks like so:
cg = mx.managers.PopUpManager.createPopUp(this, ChoiceGrid, true) as ChoiceGrid;
PopUpManager.centerPopUp(cg);
But, what I would do instead of what you're asking, is embed an IFrame in the modal popup. This is exactly what we're doing in our app to collect CC data (well, not the popup part, just the IFrame bit. http://code.google.com/p/flex-iframe/
This way, you have the standard modal dialog you're looking for, AND an internally managed 'view' out to your checkout server. Something like this:
<code:IFrame id="iFrameWithJSfunctions"
src="{checkoutURL}" />
The flex-iframe is pretty easy to work with, for the most part. You shouldn't have many problems with it.

I'm not sure you need a PopUp to do this.
Why don't you simply do:
navigateToURL(urlRequest,"_blank");
instead?
You should think of a Flex App as a self contained entity. The PopUpManager is designed to create Windows (Panels / any UIComponent) that reside over another component inside the SWF. It does not create items that pop up out of the SWF or in new browser windows.
navigateToURL could be used to create a HTML pop-up from your Flex application. However, there is very little--if any--communication between the SWF and the browser pop up. And there is no way to make a modal pop-up.
You might investigate performing an ExternalInterface call and creating your new pop up in JavaScript. Here is an article about creating modal windows in JavaScript. Before going too far down that road, I would think carefully about your requirements. How would feel if one browser window popped open another browser window and prevented you from doing any browsing until you addressed the issues in that window. Or to put it another way, how would you feel if Microsoft Word opened a word document and wouldn't let you edit any other document until you shut down the first one? I'd be pretty upset.
Modal application dialogs are one thing. And the PopUpManager allows you to create those. I would consider Model application windows a bad UI decision.
