CDirtyEditText

A subclass of LEditText which keeps track of user modifications so it is suitable in documents featuring a Save command. The class will track user changes to the document, but the programmer will need to use the SetDirty method in order to track programmatic changes.

This class does not track programmatic changes to the state of the object. The programmer will need to use the SetDirty method to indicate such changes.

CDirtyEditText is a subclass of the PowerPlant class LEditText.

CDirtyEditText requires the PowerPlant classes LEditText and LStream.

Member Data

bool
iAmDirty;

Set to true if the text in the object has been modified.

CDirtyEditText

Constructs a CDirtyEditText. Initially, the view is considered to be clean.

CDirtyEditText(
PowerPlant::LStream* inStream
);

Passes the stream to LEditText.

UserChangedText

Overrriden to set the CDirtyEditText object to dirty and update the command status.

virtual
void
UserChangedText(
void
);

IsDirty

Returns true if the CDirtyEditText object is modified (dirty) and false otherwise.

bool
IsDirty(
void
) const;

SetDirty

Allows the programmer to set the state of the CDirtyEditText. The object to should be set to dirty (true) if the programmer modifies it programmatically and it should be set to clean (false) when the object is saved.
