Detailed Description

Base class for an "editor" part.

This class handles network transparency for you. Anything that can open a URL, allow modifications, and save (to the same URL or a different one).

A read-write part can be set to read-only mode, using setReadWrite().

Part writers : Any part inheriting ReadWritePart should check isReadWrite before allowing any action that modifies the part. The part probably wants to reimplement setReadWrite, disable those actions. Don't forget to call the parent setReadWrite.

Definition at line 745 of file part.h.

Constructor & Destructor Documentation

ReadWritePart::ReadWritePart ( QObject * parent = 0 )

explicit

Constructor See parent constructor for instructions.

Definition at line 769 of file part.cpp.

ReadWritePart::~ReadWritePart ( )

virtual

Destructor Applications using a ReadWritePart should make sure, before destroying it, to call closeUrl().

In KMainWindow::queryClose(), for instance, they should allow closing only if the return value of closeUrl() was true. This allows to cancel.

Definition at line 774 of file part.cpp.

Member Function Documentation

bool ReadWritePart::closeUrl ( )

virtual

Called when closing the current url (e.g.

document), for instance when switching to another url (note that openUrl() calls it automatically in this case).

If the current URL is not fully loaded yet, aborts loading.

If isModified(), queryClose() will be called.

Returns: false on cancel

Reimplemented from KParts::ReadOnlyPart.

Definition at line 855 of file part.cpp.

bool ReadWritePart::closeUrl ( bool promptToSave )

virtual

Call this method instead of the above if you need control if the save prompt is shown.

For example, if you call queryClose() from KMainWindow::queryClose(), you would not want to prompt again when closing the url.

Equivalent to promptToSave ? closeUrl() : ReadOnlyPart::closeUrl()

Definition at line 867 of file part.cpp.

bool ReadWritePart::isModified ( ) const

Returns: true if the document has been modified.

Definition at line 1027 of file part.cpp.

bool ReadWritePart::isReadWrite ( ) const

Returns: true if the part is in read-write mode

Definition at line 1020 of file part.cpp.

bool ReadWritePart::queryClose ( )

virtual

If the document has been modified, ask the user to save changes.

This method is meant to be called from KMainWindow::queryClose(). It will also be called from closeUrl().

Returns: true if closeUrl() can be called without the user losing important data, false if the user chooses to cancel.

Definition at line 808 of file part.cpp.

bool ReadWritePart::save ( )

virtualslot

Save the file in the location from which it was opened.

You can connect this to the "save" action. Calls saveFile() and saveToUrl(), no need to reimplement.

Definition at line 872 of file part.cpp.

bool ReadWritePart::saveAs ( const KUrl & url )

virtual

Save the file to a new location.

Calls save(), no need to reimplement

Definition at line 886 of file part.cpp.

virtual bool KParts::ReadWritePart::saveFile ( )

protectedpure virtual

Save to a local file.

You need to implement it, to save to the local file. The framework takes care of re-uploading afterwards.

Returns: true on success, false on failure. On failure the function should inform the user about the problem with an appropriate message box. Standard error messages can be constructed using KIO::buildErrorString() in combination with the error codes defined in kio/global.h

bool ReadWritePart::saveToUrl ( )

protectedvirtual

Save the file.

Uploads the file, if url is remote. This will emit started(), and either completed() or canceled(), in case you want to provide feedback.

Returns: true on success, false on failure.

Definition at line 943 of file part.cpp.

void ReadWritePart::setModified ( bool modified )

virtual

Sets the modified flag of the part.

Definition at line 790 of file part.cpp.

void ReadWritePart::setModified ( )

slot

Call setModified() whenever the contents get modified.

This is a slot for convenience, since it simply calls setModified(true), so that you can connect it to a signal, like textChanged().

Definition at line 803 of file part.cpp.

void ReadWritePart::setReadWrite ( bool readwrite = true )

virtual

Changes the behavior of this part to readonly or readwrite.

Parameters

readwrite set to true to enable readwrite mode

Definition at line 782 of file part.cpp.

void KParts::ReadWritePart::sigQueryClose	(	bool *	handled,
		bool *	abortClosing
	)

signal

set handled to true, if you don't want the default handling set abortClosing to true, if you handled the request, but for any reason don't want to allow closing the document

bool ReadWritePart::waitSaveComplete ( )

slot

Waits for any pending upload job to finish and returns whether the last save() action was successful.
