gtk-sharp2.10.0.0Gtk# is thread aware, but not thread safe; See the Gtk# Thread Programming for details.Creates popup windows. boxes are a convenient way to prompt the user for a small amount of input, eg. to display a message, ask a question, or anything else that does not require extensive effort by the user.Gtk# treats a dialog as a window split vertically. The top section is a , and is where widgets such as a or an should be packed. The bottom area is known as the . This is generally used for packing buttons into the dialog which may perform functions such as cancel, ok, or apply. The two areas are separated by a .The two primary areas of a dialog can be accessed as the property and the property. To set the dialog to be modal, use the property.If you want to block waiting for a dialog to return before returning control flow to your code, you can call . This function enters a recursive main loop and waits for the user to respond to the dialog, returning the corresponding to the the user clicked.For a simple dialog, you would probably use to save yourself some effort. However, you would need to create the contents manually if you had more than a simple message in the .

Destroying the during is a very bad idea, because your post-run code will not know whether the was destroyed or not.
After returns, you are responsible for hiding or destroying the if you wish to do so.
