Any efficient/reliable way to expose one event? I have a class, MultipleDocumentCopier that copies multiple documents thru an instance of SingleDocumentCopier. SingleDocumentCopier exposes an event CopyCompleted that is fired when a file is copied. Suppose that, I am copying 10 files, instead of raising SingleDocumentCopier.CopyComplet...

It contains two JLabels, one is twice smaller and entirely covered with a bigger label. If you mouse over the labels, only the bigger one fires mouseEntered event however. import java.awt.Color; import j...
I cannot find documents about the way, in which Interface Builder determines the Sent Message outlets for the graphical connections between components triggering events and messages of other components. I want to generate components encapsulating Finite State Automata. The input part is simple, just define IBAction messages and you can c...
I have a style for a ListBox. In the listbox style I have a style for the ListBoxItems. All of this is in the section. I want to catch the IsEnabledChanged event for the Listbox Items (see this question for why). I tried setting up an EventSetter, but it can't see the event because it is not a "routed event". How can I attach an ev...
I'm trying to catch an event, when I switch the stacks of a StackLayoutPanel in GWT 2.0. The biggest problem is that I don't know which event gets fired and there seems to be no documentation, I have added a ChangeHandler with addDomHandler() but that hasn't worked. Unfortunately the StackLayoutPanel doesn't implement the getSelectedInde...

However, I would sometimes like to listen on event, so that, for example, View could start animation, or close window, when VM signals. Doing it via bool property with NotifyPropertyChanged (and starting animation only whe...

If the code execution stops before Application.Interactive = True at the end of the procedure, then the user gets locked out of the Excel. I don't ...
