Member Function Documentation

const QString LensEffectsPlugin::fullTrName ( ) const

virtual

Plug-in's human-readable, translated name.

Please don't use this for anything except display to the user. The results of testing the value of this can not be guaranteed, as its value may change depending on locale and change at runtime.

Implements ScPlugin.

const ScActionPlugin::AboutData * LensEffectsPlugin::getAboutData ( ) const

virtual

Return descriptive information about the plug-in.

Returns a structure containing descriptive information about the plug-in. This information is used in places like the Help->About Plug-ins menu item. The stucture MUST be deleted using deleteAboutData(AboutData* about) when finished with.

Every plugin MUST reimplement getAboutData(...) and deleteAboutData(...).

See also

ScPlugin::deleteAboutData

Implements ScPlugin.

void LensEffectsPlugin::languageChange ( )

virtual

Update all user-visible text to reflect current UI language.

Updates the text on all widgets on the plug-in to reflect the new language. You should generally use this method to set all the widget text during construction. That ensures that text is not duplicated, and that when this method is called the text of all persistent widgets is correctly changed.

This method only needs to affect text in widgets that currently exists (displayed or otherwise).

Implements ScPlugin.

bool LensEffectsPlugin::run ( ScribusDoc *  doc, QString  target = QString::null  )

virtual

Run the plug-in's main action.

Run the plug-in's default action synchronously, blocking the rest of the application until this method returns.

This method should generally call run(..., QIODevice* target) or run(..., QString target) to do the work. This is done by default, with the assumption that the target is a file. The argument is opened as QFile with IO_ReadOnly or IO_WriteOnly mode, depending on plugin type, and passed to run(..., QIODevice*). Override this if you need more flexibility.

The optional target argument is a plugin-defined string indicating what the plugin should operate on. It will typically be a filename to import from / export to. Nothing stops a plugin doing funky things like accepting a WebDAV URI, etc, however.

Plug-in authors might want to consider implementing this using the DeferredTask subclass used in runAsync, if the plug-in supports it.

Parameters

target

Optional target to operate on (see above)

Returns

bool True for success.

Implements ScActionPlugin.
