KIDENTITYMANAGEMENT_EXPORT QDataStreamoperator>> (QDataStream &stream, Signature &sig)

Detailed Description

Abstraction of a signature (aka "footer").

The signature can either be plain text, HTML text, text returned from a command or text stored in a file.

In case of HTML text, the signature can contain images. Since you set the HTML source with setText(), there also needs to be a way to add the images to the signature, as the HTML source contains only the img tags that reference those images. To add the image to the signature, call addImage(). The name given there must match the name of the img tag in the HTML source.

The images need to be stored somewhere. The Signature class handles that by storing all images in a directory. You must set that directory with setImageLocation(), before calling addImage(). The images added with addImage() are then saved to that directory when calling writeConfig(). When loading a signature, readConfig() automatically loads the images as well. To actually add the images to a text edit, call insertIntoTextEdit().

Example of creating a HTML signature and then inserting it into a text edit:

Signature htmlSig;
htmlSig.setText( "<img src=\"hello.png\"> World" );
htmlSig.setInlinedHtml( true );
htmlSig.setImageLocation( KStandardDirs::locateLocal( "data", "emailidentities/example/" );
QImage image = ...;
htmlSig.addImage( image, "hello.png" );
KTextEdit edit;
htmlSig.insertIntoTextEdit( KIdentityManagement::Signature::End,

Member Function Documentation

void Signature::addImage ( const QImage image,
const QString imageName 

Adds the given image to the signature.

This is needed if you use setText() to set some HTML source that references images. Those referenced images needed to be added by calling this function. The has to match the src attribute of the img tag.

If you use SignatureConfigurator, you don't need to call this function, as the configurator will handle this for you. setImageLocation() needs to be called once before.


Definition at line 585 of file signature.cpp.

void Signature::insertIntoTextEdit ( Placement  placement,
AddedText  addedText,
KPIMTextEdit::RichTextComposer textEdit,
bool  forceDisplay = false 
) const

Inserts this signature into the given text edit.

If the signature is inserted at the beginning, a couple of new lines will be inserted before it, and the cursor is moved to the beginning. Otherwise, the cursor position is preserved. For undo/redo, this is treated as one operation.

Rich text mode of the text edit will be enabled if the signature is in inlined HTML format.

If this signature uses images, they will be added automatically.

bool Signature::isInlinedHtml ( ) const
boolean whether the inlined signature is html

Definition at line 418 of file signature.cpp.

Signature & Signature::operator= ( const Signature that)

Assignment operator.

Definition at line 347 of file signature.cpp.

bool Signature::operator== ( const Signature other) const

Used for comparison.

Definition at line 540 of file signature.cpp.

QString Signature::rawText ( bool *  ok = nullptr) const
the raw signature text as entered resp. read from file.
okset to true if reading succeeded

Definition at line 359 of file signature.cpp.

void Signature::setEnabledSignature ( bool  enabled)


enabledenables signature if set as true

Definition at line 634 of file signature.cpp.

void Signature::setImageLocation ( const QString path)

Sets the location where the copies of the signature images will be stored.

The images will be stored there when calling writeConfig(). The image location is stored in the config, so the next readConfig() call knows where to look for images. It is recommended to use KStandardDirs::locateLocal( "data", "emailidentities/%1" ) for the location, where %1 is the unique identifier of the identity.

readConfig will delete all other PNG files in this directory, as they could be stale inline image files

Like with addImage(), the SignatureConfigurator will handle this for you.

void Signature::setInlinedHtml ( bool  isHtml)

Sets the inlined signature to text or html.

isHtmlsets the inlined signature to html

Definition at line 413 of file signature.cpp.

void Signature::setPath ( const QString path,
bool  isExecutable = false 

Set the signature URL and mark this signature as being of "from file" resp.

"from output of command" type.

Definition at line 407 of file signature.cpp.

void Signature::setText ( const QString text)

Set the signature text and mark this signature as being of "inline text" type.

Definition at line 623 of file signature.cpp.

QString Signature::toPlainText ( ) const

Returns the text of the signature.

If the signature is HTML, the HTML tags will be stripped.


Definition at line 571 of file signature.cpp.

Signature::Type Signature::type ( ) const
the type of signature (ie. way to obtain the signature text)

Definition at line 616 of file signature.cpp.

QString Signature::withSeparator ( bool *  ok = nullptr) const
the signature text with a "-- \n" separator added, if necessary. A newline will not be appended or prepended.
okset to true if reading succeeded
