IlvText.Editor

public class IlvTextEditor
extends IlvReshapeSelection
implements ClipboardOwner

This is the object interactor designed for an IlvTextSelection. It can handle mouse and key events and then edit the selected graphic object implementing the interface IlvTextInterface.

While editing the selected label, you can perform the following actions with your mouse:

• Click on the text to indicate the insertion position.
• Click and drag the mouse to select a zone.

With the keyboard, you can use the arrow keys to navigate in the selected label.

Tips

You can combine the <Shift> key and arrow keys to extend the selection zone.

You can also do Copy/Paste by using the Ctrl+C and Ctrl+V keys.

During the edit session you can move and reshape the selected text object:

• Drag the handles to resize the selected text object (except for fixed-size label classes such as IlvLabel);
• Drag the borders to move it.
