Detailed Description
External modification extension interface for the Document.
Introduction
The class ModificationInterface provides methods to handle modifications of all opened files caused by external programs. Whenever the modified-on-disk state changes the signal modifiedOnDisk() is emitted along with a ModifiedOnDiskReason. Set the state by calling setModifiedOnDisk(). Whether the Editor should show warning dialogs to inform the user about external modified files can be controlled with setModifiedOnDiskWarning(). The slot modifiedOnDisk() is called to ask the user what to do whenever a file was modified.
Accessing the ModificationInterface
The ModificationInterface is supposed to be an extension interface for a Document, i.e. the Document inherits the interface provided that the used KTextEditor library implements the interface. Use qobject_cast to access the interface:
// doc is of type KTextEditor::Document* KTextEditor::ModificationInterface *iface = qobject_cast<KTextEditor::ModificationInterface*>( doc ); if( iface ) { // the implementation supports the interface // do stuff }

Reasons why a document is modified on disk.
- Enumerator:
OnDiskUnmodified Not modified.
OnDiskModified The file was modified by another program.
OnDiskCreated The file was created by another program.
OnDiskDeleted The file was deleted.

Member Function Documentation
virtual void KTextEditor::ModificationInterface::modifiedOnDisk | ( | KTextEditor::Document * | document, | |
bool | isModified, | |||
KTextEditor::ModificationInterface::ModifiedOnDiskReason | reason | |||
) | [pure virtual] |
This signal is emitted whenever the document
changed its modified-on-disk state.
- Parameters:
-
document the Document object that represents the file on disk isModified if true, the file was modified rather than created or deleted reason the reason why the signal was emitted
- See also:
- setModifiedOnDisk()
virtual void KTextEditor::ModificationInterface::setModifiedOnDisk | ( | ModifiedOnDiskReason | reason | ) | [pure virtual] |
Set the document's modified-on-disk state to reason
.
KTextEditor implementations should emit the signal modifiedOnDisk() along with the reason. When the document is in a clean state again the reason should be ModifiedOnDiskReason::OnDiskUnmodified.
- Parameters:
-
reason the modified-on-disk reason.
- See also:
- ModifiedOnDiskReason, modifiedOnDisk()
virtual void KTextEditor::ModificationInterface::setModifiedOnDiskWarning | ( | bool | on | ) | [pure virtual] |
Control, whether the editor should show a warning dialog whenever a file was modified on disk.
If on
is true the editor will show warning dialogs.
- Parameters:
-
on controls, whether the editor should show a warning dialog for files modified on disk
virtual void KTextEditor::ModificationInterface::slotModifiedOnDisk | ( | View * | view = 0 |
) | [pure virtual] |
Ask the user what to do, if the file was modified on disk.
The argument view
is used to avoid asking again, when the editor regains focus after the dialog is hidden.
- Parameters:
-
view the view that should be notified of the user's decision
- See also:
- setModifiedOnDisk(), modifiedOnDisk()
