Hello, I am using wxHaskell to show a simple window with a button. A click on the button begins a task which takes a screenshot of the screen, does some computation on it and then simulates mouse clicks. Currently this task runs in the main wx thread, which makes the button unnecessarily unnresponsive for some time.
Ideally I would like to be able to run this task in a separate thread and only send the GUI related code to execute on the main thread. I can not run GUI related code on a different thread, because wx, like most GUI libraries, is not thread safe. On wxPython documentation I read that this could be possible with events, however I could not find anything in wxHaskell which corresponds to creating new custom events and wx.postEvent method, which fires the event to the main thread. This method is described here: http://wiki.wxpython.org/Non-Blocking%20Gui#Communicating_with_the_main_thread . So my question is whether it is possible to do it in the way as described in the wiki above or do you have a different solution to my problem?
