Showing a dialog at cursor

FrodeTo — Fri, 08 Dec 2017 20:27:43 GMT

I'm trying to show a dialog (or tooltip) at the cursor showing some informatin about the element. I have made a ToolPugin and overrid the GetTooltip to get the x and y coordinates. But those coordinates looks like they are inside the viewer window. And if I show a dialog at this point, it's offset from the cursor.

How do I find the cursor coordinate? Or the coordinates of the upper left corner of the viewer window would help as well. There is probably an obvious answer to this, but it eludes me.

Regards

Frode

Read about MouseMove handler in ToolPlugin class and look this usefull example: http://adndevblog.typepad.com/aec/2014/09/draw-text-graphics.html

ToolPlugin.MouseMove Method

public virtual bool MouseMove(
	View view,
	KeyModifiers modifiers,
	int x,
	int y,
	double timeOffset
)

This solution will work if I would like a text to show at the cursor like in the example in the link.

But I would like to show a dialog at the cursor. And if I use the x and y coordinates, the dialog is offset. I could need the screen coordinates of the upper left corner of the view window.

MyForm form = new MyForm();
form.location = new System.Drawing.Point(x, view.Height - y);
form.Show();

It seems I recognize that you want.

Autodesk.Navisworks.Api.Application class contains Gui propery.

By this property is possible to get IWin32Window interface of MainWindow that gives Handle of main window.

I believe, having main window handle, it is possible to get mouse position in the screen coordinates.

Sorry I am using WPF so sent you to long way.

Take a look to Position property of System.Windows.Forms.Cursor class.

It gives you cursor position in the screen coordinates.

Thank you for the help. I now use the mainWindow together with the x and y to get the correct screen coordinates.

Hey,

Can you explain how to get this offset ?

I would like to get x and y offset between Window's (the OS) origine and Naviswork's render window

Autodesk.Navisworks.Api.Application.Gui.MainWindow and what should I do after that ?

Thanks
