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 96 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 51 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 79 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 84 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 100 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 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 37 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
