Detailed Description

External modification extension interface for the Document.


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*
auto iface = qobject_cast<KTextEditor::ModificationInterface*>(doc);
if (iface) {
// the implementation supports the interface
// do stuff
} else {
// the implementation does not support the interface

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.

◆ 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.

Implemented in KTextEditor.

◆ setModifiedOnDiskWarning()

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.
