virtual ~CustomHttpLinkUIPlaceButtonObserver() {}

virtual void AutoAttach();

}

{
if (theChange == kTrueStateMessage)
{
// Check for the widget id
InterfacePtr<IControlView> view(this, UseDefaultIID());
WidgetID widgetid = view->GetWidgetID();
if (widgetid == kGetTextButtonWidgetID)
{
CAlert::InformationAlert("1");
InterfacePtr<IPanelControlData> panelControlData(this, UseDefaultIID());
IControlView* EditTextBoxView = panelControlData->FindWidget(kSampleTextEditBoxWidgetID);
InterfacePtr<ITextControlData> EditBoxTextData(EditTextBoxView, UseDefaultIID());
PMString temp;
temp = EditBoxTextData->GetString();
PMString returnText = temp;
CAlert::InformationAlert(returnText);
}
}
}
