\class IAssistProposalWidget
\brief The IAssistProposalWidget is an interface for widgets that display assist proposals.
Known implenters of this interface are FunctionHintProposalWidget and GenericProposalWidget.
The former is recommeded to be used when assisting function calls constructs (overloads
and parameters) while the latter is quite generic so that it could be used to propose
snippets, refactoring operations (quickfixes), and contextual content (the member of class
or a string existent in the document, for example).
In general this API tries to be as decoupled as possible from the base text editor.
This is in order to make the design a bit more generic and allow code assist to be
pluggable into different types of documents (there are still issues to be treated).

/*!
\fn void setAssistant(CodeAssistant *assistant)
Sets the code assistant which is the owner of this widget. This is used so that the code
assistant can be notified when changes on the underlying widget happen.
*/
/*!
\fn void setReason(AssistReason reason)
Sets the reason which triggered the assist.
*/
/*!
\fn void setUnderlyingWidget(const QWidget *underlyingWidget)
Sets the underlying widget upon which this proposal operates.
*/
/*!
\fn void setModel(IAssistModel *model)
Sets the model.
*/
/*!
\fn void setDisplayRect(const QRect &rect)
Sets the \a rect on which this widget should be displayed.
*/
/*!
\fn void showProposal(const QString &prefix)
Shows the proposal. The \a prefix is the string comprised from the character at the base
position of the proposal until the character immediately after the cursor at the moment
the proposal is displayed.
\sa IAssistProposal::basePosition()
*/
/*!
\fn virtual void updateProposal(const QString &prefix)
Updates the proposal base on the give \a prefix.
\sa showProposal()
*/
/*!
\fn void closeProposal()
Closes the proposal.
*/
/*!
\fn void setIsSynchronized(bool isSync)
Sets whether this widget is synchronized. If a widget is synchronized it means that from
the moment a proposal started being computed until the moment it is actually displayed,
there was no content input into the underlying widget.
A widget is not synchronized in the case a proposal is computed in a separate thread and
in the meanwhile (while it is still being processed) content is input into the underlying
widget.
*/
/*!
\fn void prefixExpanded(const QString &newPrefix)
The signal is emitted whenever this widget automatically expands the prefix of the proposal.
This can happen if all available proposal items share the same prefix and if the proposal's
model supports prefix expansion.
\sa IGenericProposalModel::supportsPrefixExpansion()
*/
/*!
void proposalItemActivated(IAssistProposalItem *proposalItem)
This signal is emitted whenever \a proposalItem is chosen to be applied.
