Interface IdeEditorPositionConverter

public interface IdeEditorPositionConverter

Provides the forward and reverse conversion from the file offset to TextPosition object.

The methods of this interfaces are very useful when you are working with text editor - its position-related methods operate with the TextPosition objects, while RWI properties like START_POSITION or DEFINITION_START_POSITION contain the offset values.

For example:

 import com.togethersoft.openapi.rwi.RwiProperty;
 import com.togethersoft.openapi.ide.editor.IdeEditor;
 import com.togethersoft.openapi.ide.editor.IdeEditorManager;
 import com.togethersoft.openapi.ide.editor.IdeEditorManagerAccess;
 import com.togethersoft.openapi.ide.editor.IdeEditorVisibleArea;
   ...
 IdeEditorManager editorManager = IdeEditorManagerAccess.getEditorManager();
 int startOffset = Integer.parseInt(someRwiElement.getProperty(RwiProperty.START_POSITION));
 TextPosition textPos = editor.getPositionConverter().offsetToCell(startOffset);
 IdeEditorVisibleArea viewArea = editor.getVisibleArea();
 viewArea.setFirstColumn(textPos.getColumn());
 viewArea.setFirstLine(textPos.getLine());
