Description datnhanlz 2013-09-24 23:25:38 EDT
System.Windows.Forms.NotifyIcon does not show up in the systray (Tested on OS:
Fedora, Arch. DE: MATE, Cinnamon)
When I try to fix the problem, I found the following line of code cause the
bug:

File: XplatUIX11.cs, method: SystrayAdd, line: 6024
XChangeProperty(DisplayHandle, hwnd.whole_window, _XEMBED_INFO, _XEMBED_INFO,
32, PropertyMode.Replace, atoms, 2);

When I commented out (removed) the line aboved. The icon show up correctly in
the systray. Right-click also works as expected. Only minor problem is that the
mouse cursor change slightly (I think it change to XServer cursor???)

Because I am a newbie to Linux, hence, I have no knowledge about XServer. I am
not sure what that line of code for. I stopped my effort here and report this
as a bug in the hope that the experts can fix this faster than me. Personally,
I will run my application without that line of code.

(It seems simple, but cost me a lot of time. Trying countless time to compile
Mono, MonoDevelop on Fedora to get the latest version of Mono, but always fail.
Eventually, I installed Arch Linux to get the newest Mono 3.2.x, and found out
the problem still there :D)

Sorry for my English.

Setting priority to lowest, since Windows.Forms is no longer being developed
actively.

Remove the line from sources

I have the same behaviour as in this bug (on Calculate Linux/LXDE). Removing
that line helps from the first sight. I tested on the sample
https://github.com/mono/winforms/blob/master/notifyicon/swf-notifyicon.cs
