(new in Rev2.40)
MQStationPlugin class inherits MQBasePlugin class, and provides functions necessary for an implementation of a station plug-in.
You can make a station plug-in with a simple implementation and without taking care of complex message procedures between a plug-in and a main part of Metasequoia by inheriting this MQStationPlugin class and implementing required virtual functions.
In MQCommandPlugin class, each plug-in member functions and messages are declared as virtual functions. It is necessary to implement the virtual function in the inherited class.

This method implements a virtual function declared by MQBasePlugin::GetPlugInType(). No additional implementation is not necessary in an inherited class.
virtual const char *MQStationPlugin::EnumString();
It returns a display string in a menu (for Station plug-in) or on a button (for Command plug-in).
This method is declared as a pure virtual function, and it disappears MQEnumString() by implementing in the inherited class.
virtual BOOL MQStationPlugin::Initialize();
This method is called when Metasequoia starts up or after loading the plug-in DLL by the "About plug-ins" dialog.
This method is declared as a pure virtual function, and you must implement in an inherited class. Though what to be implemented is not specified, it generally creates a window displayed when it is called from a menu.
Attention: In Ver2.4.3 or older version, Initialize() is also called multiply after loading the DLL for a bug. It is only called just after loading the DLL in Ver2.4.4 or later version
virtual void MQStationPlugin::Exit();
This method is called when Metasequoia quits or before unloading the plug-in DLL by the "About plug-ins" dialog.
This method is declared as a pure virtual function, and you must implement in an inherited class. Though what to be implemented not specified, it generally releases resources allocated by Initialize().
virtual BOOL MQStationPlugin::Activate(MQDocument doc, BOOL flag);
This method is called to changed the activation state when the menu for this plug-in is clicked.
This method is declared as a pure virtual function, and you must implement in an inherited class. Though what to be implemented is not specified, it generally shows or hides a window created by Initialize().
Regardless of the required active-state, it must return the active-state after calling this function.
virtual BOOL MQStationPlugin::IsActivated(MQDocument doc);
It returns whether this plug-in is active.
This method is declared as a pure virtual function, and you must implement in an inherited class.

(new in Rev2.41)
This method is called when a message by MQBasePlugin::SendUserMessage() is sent from the other plug-in.
This method is declared as a virtual function, and it does nothing in a default action. You can exchange data between plug-ins by implementing in an inherited class and a sender plug-in if necessary.
virtual void MQStationPlugin::OnDraw(MQDocument doc, MQScene scene, int width, int height);
This method is called when the drawing a scene.
This method is declared as a virtual function, and it does nothing in a default action. You can draw your own plug-in object in the scene by implementing in the inherited class if necessary.
An object or a material used only while a drawing can be created by CreateDrawingObject() or CreateDrawingMaterial().
virtual void MQStationPlugin::OnNewDocument(MQDocument doc, const char *filename, NEW_DOCUMENT_PARAM& param);
This method is called when a document is initialized.
filename is set only when a MQO file has been loaded, and it is NULL when other format file has been imported.
If a XML element has been registered through OnSaveDocument() when saving a file, the XML element will be set in param.elem.
This method is declared as a virtual function, and it does nothing in a default action. You can do some operations by implementing in the inherited class if necessary.
struct NEW_DOCUMENT_PARAM { MQXmlElement elem; };
|
virtual void MQStationPlugin::OnEndDocument(MQDocument doc);
This method is called when a document exits.
This method is declared as a virtual function, and it does nothing in a default action. You can do some operations by implementing in the inherited class if necessary.
When a drawing object or a material created by CreateDrawingObject() or CreateDrawingMaterial() which instant is FALSE remains, please delete it by DeleteDrawingObject() or DeleteDrawingMaterial() in this function.
virtual void MQStationPlugin::OnSaveDocument(MQDocument doc, const char *filename, SAVE_DOCUMENT_PARAM& param);
This method is called just before saving a document to a MQO file.
A XML element is set in param.elem, and plug-in own data can be saved together with a .MQO file by registering the child element. The XML element is saved in an external XML file, and it is linked from a MQO file.
This method is declared as a virtual function, and it does nothing in a default action. You can do some operations by implementing in the inherited class if necessary.
