I'm investigating Mono as a possible solution for porting a Windows Forms based app to OS X.
As a test, I've created a small C# app. The Main form contains a button which invokes another window with the following code in the _Click() event: Form2 f2 = new Form2(); f2.ShowDialog(); f2.Dispose(); Form2 has a button which just calls "Close();" No other real code in the test app. I'm running into problems on a Mac OS X Lion (10.7.5) computer, I've installed/tested the app against Mono SDK 2.10.9 and 3.0.1. I've also tried binaries compiled with MonoDevelop (3.0.5) as well as one from VS 2010. Testing involves clicking Form1's Button #1 (to show Form2) and Button #2 (on Form 2) to close Form2. Clicking these buttons over and over eventually causes the mono app to bring up 3 to 5 simultaneous Form2s. The "topmost" Form2 is the normal one w/ default coloring and Button #2. However, the underneath dialogs are "blank" windows w/ a white background and no layout of any kind for Button #2. You cannot even close these forms w/ the "X" close button. After this occurs, if I close Form1, the mono process hangs, and Ctrl-C is req'd to kill the process. Also, the following is displayed in the shell which launched the app: user$ mono WindowsFormsMonoTest.exe Nov 27 18:35:16 comp-lion.local mono[210] <Error>: kCGErrorInvalidConnection: CGSGetWindowTags: Invalid connection Nov 27 18:35:16 comp-lion.local mono[210] <Error>: kCGErrorFailure: Set a breakpoint @ CGErrorBreakpoint() to catch errors as they are logged. ^C Has anyone seen this before? Seems like a simple case which should work under Mac OS X. Can anyone suggest possible solutions? Is it a mismatch between X11 and/or GTK versions and Mono? Any other possibilities? BTW, I have the sample source if anyone would like to see this firsthand.
