Using Mono to Click the Mouse in C# - Mac OS

Question

I have written an application (wpf - will Mono translate this for a Mac?) that I wish to somehow port across to Mac OS X. This application involves using user32.dll to perform a mouse click (something like this):

[DllImport("user32.dll")]
    static extern void mouse_event(int dwFlags, int dx, int dy, int dwData, int dwExtraInfo);
 mouse_event(MOUSEEVENTF_LEFTDOWN, 0, 0, 0, 0);
 mouse_event(MOUSEEVENTF_LEFTUP, 0, 0, 0, 0);

I have heard Mono is useful for making applications for multiple platforms - is there a way that I can use this to make my code compatible with a Mac?

If not, is there a way that I can invoke a mouse click using the Mac equivalent of user32.dll? And a way to detect whether the program is running in Windows or Mac OS to choose which bit of code to run?

are you trying to generate the mouse click against something in your application, or against another application — Mark Hall, Feb 01 '11 at 16:38
I'm trying to click in another application - my app is minimised while it runs. — Jack, Feb 01 '11 at 20:17
Mono is not compatible with WPF. You need to use WinForms. I have spent a lot of time googling a Mac equivalent of user32.dll, I was unable to find a 'managed' version of mouse_event. — , Apr 03 '11 at 10:23

Mono currently does not plan to support WPF see Link.
Take a look at this SO question to see if it helps and you may want to look into using Silverlight since it is supported by Microsoft on the Mac.

Also you are calling a Win32 native function - those are not supported on Mac. Your best bet would be using cross-platform .NET-strict code.

Do you know what .NET-strict code I can use to perform a mouse click? I have looked into it before but could not find how to do it without using user32.dll... – Jack Feb 01 '11 at 08:51
It is a capability tied to the system - you have to invoke the API directly in Windows because there is no .NET implementation for it. There is similar capability available for Mac (http://stackoverflow.com/questions/1483657/performing-a-double-click-using-cgeventcreatemouseevent) but I am not sure you can use it in Mono. – Den Feb 01 '11 at 16:02

You can try looking at Apple's CG API, there is a function CGEventCreateMouseEvent

Mono does not support WPF and currently has no future plans to support it. I looked into this on the weekend myself.

If you are going to use mono with GUI applications, I advise you use WinForms instead as this is implemented in Mono.

Here is the full list of Mono implemented features - http://mono-project.com/Compatibility

This does not answer the question; he is asking if there is an equivalent way to simulate a mouse click using Mono on OS X, not whether it is possible to port over a WPF application. – Callum Rogers Jan 12 '14 at 20:27
