Detailed Description

Controller interface for a CodeCompletionModel.

The CodeCompletionModelControllerInterface gives an CodeCompletionModel better control over the completion.

By implementing methods defined in this interface you can:

• control when automatic completion should start (shouldStartCompletion())
• define a custom completion range (that will be replaced when the completion is executed) (completionRange())
• dynamically modify the completion range during completion (updateCompletionRange())
• specify the string used for filtering the completion (filterString())
• control when completion should stop (shouldAbortCompletion())

When the interface is not implemented, or no methods are overridden the default behaviour is used, which will be correct in many situations.

Implemeting the Interface

To use this class implement it in your CodeCompletionModel.

class MyCodeCompletion : public KTextEditor::CodeCompletionTestModel,
                 public KTextEditor::CodeCompletionModelControllerInterface
{
  Q_OBJECT
  Q_INTERFACES(KTextEditor::CodeCompletionModelControllerInterface)
public:
  KTextEditor::Range completionRange(KTextEditor::View* view, const KTextEditor::Cursor &position);
};

Member Function Documentation

void KTextEditor::CodeCompletionModelControllerInterface::aborted ( KTextEditor::View *  view )

virtual

Notification that completion for this model has been aborted.

Parameters

view	The view in which the completion for this model was aborted

Definition at line 100 of file codecompletionmodelcontrollerinterface.cpp.

Range KTextEditor::CodeCompletionModelControllerInterface::completionRange ( View *  view, const Cursor &  position  )

virtual

This function returns the completion range that will be used for the current completion.

This range will be used for filtering the completion list and will get replaced when executing the completion

The default implementation will work for most languages that don't have special chars in identifiers.

Parameters

view	The view to generate completions for
position	Current cursor position

Returns

the completion range

Definition at line 54 of file codecompletionmodelcontrollerinterface.cpp.

QString KTextEditor::CodeCompletionModelControllerInterface::filterString ( View *  view, const SmartRange &  range, const Cursor &  position  )

virtual

This function returns the filter-text used for the current completion.

Can return an empty string to disable filtering.

The default implementation will return the text from range start to the cursor position.

The smart-mutex is not locked when this is called.

Parameters

view	The view to generate completions for
range	The completion range
position	Current cursor position

Returns

the string used for filtering the completion list

Definition at line 83 of file codecompletionmodelcontrollerinterface.cpp.

bool KTextEditor::CodeCompletionModelControllerInterface::shouldAbortCompletion ( View *  view, const SmartRange &  range, const QString &  currentCompletion  )

virtual

This function decides if the completion should be aborted.

Called after every change to the range (eg. when user entered text)

The default implementation will return true when any special character was entered, or when the range is empty.

The smart-mutex is not locked when this is called.

Parameters

view	The view to generate completions for
range	The completion range
currentCompletion	The text typed so far

Returns

true, if the completion should be aborted, otherwise false

Definition at line 88 of file codecompletionmodelcontrollerinterface.cpp.

bool KTextEditor::CodeCompletionModelControllerInterface::shouldExecute ( const QModelIndex &  selected, QChar  inserted  )

virtual

When an item within this model is currently selected in the completion-list, and the user inserted the given character, should the completion-item be executed? This can be used to execute items from other inputs than the return-key.

For example a function item could be executed by typing '(', or variable items by typing '.'.

Parameters

selected	The currently selected index
inserted	The character that was inserted by tue user

Definition at line 104 of file codecompletionmodelcontrollerinterface.cpp.

bool KTextEditor::CodeCompletionModelControllerInterface::shouldStartCompletion ( View *  view, const QString &  insertedText, bool  userInsertion, const Cursor &  position  )

virtual

This function decides if the automatic completion should be started when the user entered some text.

The default implementation will return true if the last character in insertedText is a letter, a number, '.', '_' or '>'

Parameters

view	The view to generate completions for
insertedText	The text that was inserted by the user
userInsertion	Whether the text was inserted by the user using typing. If false, it may have been inserted for example by code-completion.
position	Current cursor position

Returns

true, if the completion should be started, otherwise false

Definition at line 39 of file codecompletionmodelcontrollerinterface.cpp.

void KTextEditor::CodeCompletionModelControllerInterface::updateCompletionRange ( View *  view, SmartRange &  range  )

virtual

This function lets the CompletionModel dynamically modify the range.

Called after every change to the range (eg. when user entered text)

The default implementation does nothing.

The smart-mutex is not locked when this is called.

Warning

Make sure you lock it before you change the range

Parameters

view	The view to generate completions for
range	Reference to the current range
