public event EventHandler<AnnEditTextEventArgs> EditText 
- (void)automation:(LTAnnAutomation *)automation editText:(LTAnnEditTextEventArgs *)args; 
public void addEditTextListener(AnnEditTextListener listener) 
public void removeEditTextListener(AnnEditTextListener listener) 
   event EventHandler<AnnEditTextEventArgs^>^ EditText 
def EditText(sender,e): # sender: AnnAutomation e: Leadtools.Annotations.Engine.AnnEditTextEventArgs 
Event Data

The event handler receives an argument of type AnnEditTextEventArgs containing data related to this event. The following AnnEditTextEventArgs properties provide information specific to this event.

Bounds Gets the bounding rectangle of the AnnTextObject entering text-editing mode in screen/device coordinates.

This event will occur when the object being edited is a text object and the user initiates edit mode. For more information, refer to AnnTextEditDesigner.EditText.

If the value of EditTextAfterDraw is set to true, then this event will occur automatically after the designer finishes drawing new text objects.


This example will show how to change the string used by an annotation text object when it enters edit mode.

Start with the AnnAutomationManager example, remove all the code inside the example function (search for the // TODO: add example code here comment) and insert the following code:

Click the example button then draw a text object and double click on it.

using Leadtools.Annotations.Automation; 
using Leadtools.Annotations.Engine; 
using Leadtools.Codecs; 
using Leadtools.Controls; 
using Leadtools.Annotations.Rendering; 
using Leadtools.Annotations.WinForms; 
public void AnnAutomation_EditText() 
   // Hook to the automation's EditText event 
   _automation.EditText += _automation_EditText; 
void _automation_EditText(object sender, AnnEditTextEventArgs e) 
   // In your application, you could show a dialog to enter the new text value or create 
   // a text element on the page for editing 
   // e is of type AnnEditTextEventArgs 
   // Get the text annotation object 
   AnnTextObject textObj = e.TextObject; 
   // Change its text 
   textObj.Text = "After edit"; 
   // Invalidate it
