Eclipse plug-in development learning note "6"---add editor

We use the Myfirstplugin example, and we open three different editors at 111,222,333 clicks in viewlist.

First, we click Add in the Plugin.xml extension tab, select the Org.eclipse.ui.editors extension point, and click Finish.

Right-click the extension point to create a new two editor, altogether three editor, as shown in the properties:

Right-click on the SRC folder to create a new class, create 3 classes for Editor1,editor2,editor3, and inherit the EditorPart class.

Add the implementation code to the INIT and Createpartcontrol functions:

SetSite (site);

SetInput (input);

Setpartname (Input.getname ());

Settitleimage (Input.getimagedescriptor (). CreateImage ());

Composite topcom = new Composite (parent, SWT. NONE);

Topcom.setlayout (new filllayout ());

New Text (topcom, SWT. MULTI). SetText ("Editor 1");

Create a new Inputeditor1-3 3 class to implement the Ieditorinput interface. The Getimagedescriptor and GetName methods add the following code:

Return Workbenchimages.getimagedescriptor (Iworkbenchgraphicconstants.img_dtool_new_fastview);

Return "111";

Add the following code to the Viewlist:

List.addmouselistener (new MouseListener () {

@Override

Public void MouseDoubleClick (MouseEvent e) {

Ieditorinput input = null;

String id = NULL;

Switch (List.getselection () [0]) {

Case "111":

input = INPUT1;

id = "Myfirstplugin.editors.Editor1";

break;

Case "222":

input = Input2;

id = "Myfirstplugin.editors.Editor2";

break;

Case "333":

input = INPUT3;

id = "Myfirstplugin.editors.Editor3";

break;

}

if (input = = NULL | | id = = null)

return;

Ieditorpart editor = Getsite (). GetPage (). Findeditor (input);

if (Editor! = null) {

Getsite (). GetPage (). Bringtotop (editor);

}

Else {

Try {

Getsite (). GetPage (). Openeditor (input, id);

} catch (Exception E2) {

E2.printstacktrace ();

}

}

}

@Override

Public void MouseDown (MouseEvent e) {

TODO Auto-generated method stubs

}

@Override

Public void mouseUp (MouseEvent e) {

TODO Auto-generated method stubs

}

});
