StatusBar ContextMenu Position

[Anonymous]

Hello,

I have created a TrayItem that exists in the StatusBar; i use it to notify the user of activity via the the balloon notifications. I know want it as the source of an AboutBox, which I want via a right-click context menu as is traditional.

I have the following:

Snippet

                     ...
                     trayItem.MouseDown += TrayItem_MouseDown;
                }
 
                return trayItem;
            }
        }
 
        private static void TrayItem_MouseDown(object sender, StatusBarMouseDownEventArgs e)
        {
            if (e.Button == WinForms.MouseButtons.Right)
            {
                WinForms.ContextMenu contextMenu = new WinForms.ContextMenu();
 
                WinForms.MenuItem about = new WinForms.MenuItem("About...");
 
                contextMenu.MenuItems.Add(about);
                trayItem.DisplayContextMenu(contextMenu, new Point(e.X, e.Y));
            }
        }

Which I have found scouring the internet. And it does create and display my context menu with About option.

However, it displays it in relation to the origin at top left corner(ish) of the whole status bar, when the StatusBarMouseDownEventArgs X and Y values are in relation to the top left of the TrayItem "window".

What am I missing?

Secondly, the Autodesk.AutoCad.Windows namespace has it's own menu classes but DisplayContextMenu demands a System.Windows.Forms class, so the context menu will not keep the look and feel of AutoCAD.

If anybody knows their way around this area, that would be incredibly stress reducing for me.

Thanks.

Hi,

Can you please explain in detail what is your expected behavior, and also it helps us if you are able to give non-confidential project and steps to reproduce the behaviors.

Most of the times  code snippets will not help us to understand the context in which your code executes.

May be it will help other experts in this forum to get clue or hint whats going wrong.

Hi,

try using "Cursor.Position" 

void _ti_MouseDown(object sender, StatusBarMouseDownEventArgs e)
{
    if (e.Button == MouseButtons.Right)
    {
        _ti.DisplayContextMenu(m_ContextMenu, Cursor.Position);
    }
}

full sample code

 public class MyCommands
    {
        TrayItem _ti;
        System.Windows.Forms.ContextMenu m_ContextMenu = null;
        System.Windows.Forms.MenuItem _mi = null;

        [CommandMethod("TestTray", CommandFlags.Modal)]
        public void TestTrayMethod()
        {
            if (m_ContextMenu == null)
            {
                m_ContextMenu = new System.Windows.Forms.ContextMenu();
                m_ContextMenu.Name = "MyMenu";

                _mi = new System.Windows.Forms.MenuItem();
                _mi.Click += mi_Click;
                _mi.Name = "TestClick 1";
                _mi.Text = "TestClick 1";
                m_ContextMenu.MenuItems.Add(_mi);

                _mi = new System.Windows.Forms.MenuItem();
                _mi.Click += mi_Click2;
                _mi.Name = "TestClick2";
                _mi.Text = "TestClick2";
                m_ContextMenu.MenuItems.Add(_mi);
                
            }

            Autodesk.AutoCAD.Windows.StatusBar sb = Autodesk.AutoCAD.ApplicationServices.Application.StatusBar;
            TrayItemCollection tic = sb.TrayItems;
            if (_ti == null)
            {
                _ti = new TrayItem();
                _ti.Icon = System.Drawing.SystemIcons.Asterisk;
                _ti.ToolTipText = "Tooltip";
                _ti.MouseDown += _ti_MouseDown;
                tic.Add(_ti);

                _ti.Visible = true;
                sb.Update();
            }
        }

        void _ti_MouseDown(object sender, StatusBarMouseDownEventArgs e)
        {
            if (e.Button == MouseButtons.Right)
            {
                _ti.DisplayContextMenu(m_ContextMenu, Cursor.Position);
            }
        }

        void mi_Click(object sender, EventArgs e)
        {
            MessageBox.Show("Test click 1");
        }
        void mi_Click2(object sender, EventArgs e)
        {
            MessageBox.Show("Test click 2");
        }
    }

I thought that was it!

However, I then get this (bottom of AutoCAD window top left):

Cursor.Position always seems to be (~500, ~500), but because the Point p parameter of DisplayContextMenu is in relation to the StatusBar window, the menu appears as above.

Hopefully this makes it clear as to the problem in my original post.

How do I get the position of the cursor within the region of the StatusBar window, when I right click on my tray item.

Using StatusBarMouseDownEventArgs e.X and e.Y give the coordinates of the cursor within the TrayItem icon i.e. x and y are between (0,0) and (15, 15). In that regard the context menu appears here:

Thanks.

Have you tried looking at the StatusBarItem's PointToClient() and PointToScreen() methods?

[Anonymous]

Yeh, I did find those methods, however, they then related the point from the event to the AutoCAD window, so the menu would appear at the top of the screen.

[Virupaksha_aithal]

Hi,

I have reported this behavior to AutoCAD engineering team. 

[Anonymous]

Further to the above.

I've just tried using the Cursor.position point as the parameter to the trayItem.PointToClient method and we are a step closer. This then does pop the context menu up with the mouse point at the top-left hand corner of the context menu, see image below.

I'm still interested in how to create a AutoCAD styled context as can be seen by right clicking on any of the standard tray items. I cannot find anything online:

AutoCAD:              Custom:

I am using a WinForms context menu so the style is understandable. Is there some AutoCAD API data methods for this. Is this described in any AutoCAD .NET help text - I've tried to search in the .Net Dev Guide with no luck.

Hi,

I have been going a bit crazy lately trying to hook up a context menu to a Pane using the same method outlined in this thread.  I doubled back and used the identical code posted here using the tray icon.  All works well with the exception that the click event will not fire for any menu items added to the context menu.  Following microsoft support, I made sure not to add any sub menu items which turn off the the click event, yet no success.  I have implemented many different methods for adding the items.  All with no success.  Neither the Pane nor a Tray Item will allow a click event on the context menu.

Currently I have the exact code posted here and get the same result.  I am at a total loss for getting it to work.  I have even implemented a custom item implementing a click event and still can not get it to fire.

I am currently building and testing on civil3d 2015.  Could this be known bug?

Thank you in advanced.

I know you said you're using the exact code posted here, but after looking at it, there doesn't seem to be any problems with that code.

So, I don't know if anyone can help you without seeing your exact code attempt.  If you add the menu items to the context menu and set their Click handler, the click event should fire.

[chris.bertschy]

Yes, I agree, I saw it and said the same thing.  It looks like every example I found from many sources.  But no matter how I add a context menu to anything, the click event will not fire.    Below is the code.  It went through a hatchet job with hours of abuse trying many different methods not shown below.  It all works as expected with using either a Pane added to the status bar or the Tray Item.  Currently it is set to use the tray. Other code I have tried include using  StartusBar.MenuItem ; Controls.Context menu instead of windows.form.contextmenu.  Created custom implementation of menuitems with my own events.  All worked but just can't get the context menu to fire.  I was hoping there was some small tidbit of understanding I missed or acknowledgement of a bug with this in civil3d 2015.

This is code I use, for invoking an About dialog. This works. I hope it can help.

I assume you've tried without the

new StatusBarMouseDownEventHandler

 and just assigning it a method name as in examples in this thread?

Otherwise looks fine. Are you sure the menu isn't appearing somewhere else on screen, because the use of Cursor.Position directly does not invoke the menu at the click site. See where I have used PointToClient function.

private static TrayItem TrayItem
{
	get
	{

		{
			trayItem = new TrayItem();
			trayItem.Icon = new Icon((Icon)Resources.ResourceManager.GetObject("StatusBarTrayIcon"), 16, 16);
			trayItem.MouseDown += TrayItem_MouseDown;
		}

		return trayItem;
	}
}

public static void WriteStatusBubble(string title, string message, IconType iconType)
{
	TrayItemBubbleWindow bw = new TrayItemBubbleWindow();
	bw.Title = title;
	bw.Text = message;
	bw.IconType = iconType;

	TrayItem.CloseBubbleWindows();
	TrayItem.ShowBubbleWindow(bw);
	Application.StatusBar.Update();
}

}

}

private static void TrayItem_MouseDown(object sender, StatusBarMouseDownEventArgs e)
{

	{

		WinForms.MenuItem about = new WinForms.MenuItem("About...");
		about.Click += About_Click;

		contextMenu.MenuItems.Add(about);

		Point point = trayItem.PointToClient(WinForms.Cursor.Position);
		trayItem.DisplayContextMenu(contextMenu, point);
	}

Thank you Ryan,

I was curious if you had trouble with it.  I was not sure if you were still working through the position of the context menu and how you handled it.  It did try removing the '

new StatusBarMouseDownEventHandler

I also tried using a custom handler with a custom menu items class.  Oddly enough, if I call preformclick() on the menu item, it works.  I can even add sub menu's and it does roll out with the sub menu items, but no click response on those as well.  Very strange.  I shudder at having to add a WPF form to the project and use it instead of the context menu. 

It would also be nice if the look of the context menu matched that of the 'out of the box' status bar menu's.

What isn't shown in your code, is the execution context. Where is your class's constructor called from?  is it called in the application context or the document context?  You can check DocumentCollection.IsApplicationContext to be sure. It may be that the context menu needs to be created in the application context.

[chris.bertschy]

The project that all of this resides in is over 4,000 lines of code.  But for brevity, it loads the status bar items through the initialization of IExtensionApplication.  So I would definitely say that it is using the application context for loading.  

    public class pdApplication : IExtensionApplication
    {
        
        #region IExtensionApplication Members

        void IExtensionApplication.Initialize()
        {
 
#if DATA_LOGGER

            try
            {
                Logger.LoggerStatusBar = new LoggerPane();
               <misc code here>........................................................
             .........................................................
            {

Logger.LoggerStatusBar is a public static member with getter and setter that is back by a private field.  All works, just the click event will not fire.  As if it was turned off at the menuitem component level when subitems are present.

 public static class Logger
    {
        private static LoggerPane _LoggerStatusBar;
        public static LoggerPane LoggerStatusBar
        {
            get { return _LoggerStatusBar; }
            set { _LoggerStatusBar = value;}
        }
    
<more code>........................

     }

Initialize() can be called in either execution context.  It depends on how the assembly is loaded.

The .net DLL autoloads and the IExtensionApplication.Initialize() is run for the session or the life of the DLL being loaded.  At least that is how I have understood it and they way it has been behaving.  I

did do something a bit dumb by using a private static field to back the property.  I figured a static auto property would have created a behind the scene private field anyway so I just implemented it.  Probably doesn't need to be static as it is part of the loaded application.

I am going to remove it and let change it to a static auto property and see if it helps.

Hey,

To confirm, I call InitialiseTrayItem() from the IExtensionApplication.Intiallize() method as you do...

Have you tried creating the tray item as a static member? Maybe it's getting destroyed.

Have you tried creating the context menu everytime? within the callback method, as it's required?

I feel your struggle with AutoCAD API, it can be frustrating.

[chris.bertschy]

Ryan,

Yes, I tried creating the context menu on the fly on the initial Tray item click.  Same result.  I second that it must be destroying the handlers added to the event.  Makes since because it does disappear on click where as if it was disabled, I would imagine it would stay on the screen.  Super frustrating.

I lack the debug know how to watch a delegate or system event in action.

You can try using the following to initialize your application.

It is designed to ensure that regardless of how the assembly is loaded, the Initialize() method always runs in the application context.
