About plugins Plugins are components with a GUI that perform some action for Chalk. Note that plugins are only loaded when a KisView is constructed; note also that every plugin is reloaded when a new KisView is created. Plugins are _not_ allowed to depend on each other. You may _not_ #include a header file from a plugin anywhere but in that same plugin. You can however choose to group a cluster of related functions in one plugin, like with the selection tools. There are several kinds of plugins for Chalk: * Tools Tools have the Chalk/Tool servicetype. A tool plugin registers the tool factories it provides with the tool registry. A tool must descend from the KisTool interface. There are several base classes for specialized tools, like painting and non painting tools. * Paintops Paintops implement methods for changing pixels that can be used by painting tools. Examples are brush, pen, airbrush. Paintop plugins have the Chalk/Paintop servicetype, register paintop factories they provide the paintop registry. Paintops inherit KisPaintOp. * Filters Filters implement methods of changin a rectangular area of pixels. Filter plugins have the Chalk/Filter servicetype and are registered with the filter registry. A filter inherits the KisFilter class and may provide a configuration widget and a configuration object. * Extensions Extensions are loaded by every view instance. They provide user interface elements such as dialog boxes and wizards. Their parent is KisView and they provide an .rc file to merge their gui with the view gui. Extensions have the servicetype Chalk/Plugin. They are not loaded automatically by the KParts mechanism; please do not create ordinary kparts that are to be loaded by the Chalk view since KParts are not versioned.
