Method/Function: AsHyperText

AccessibleWrap is a C++ library that provides classes and methods for interacting with accessibility technologies within an operating system. It allows developers to create accessible applications that can be used by individuals with disabilities.

AsHyperText is a method provided by AccessibleWrap that can be used to retrieve the text content of an accessibility object as a hyperlinked string. This method is useful for creating accessible text displays within an application.

Example 1:

// Retrieve an accessibility object
IAccessible* obj = GetAccessibleObjectFromWindow(hwnd);

// Retrieve the hyperlinked text content of the object
BSTR text = AccessibleWrap::AsHyperText(obj);

// Display the text in a label control
SetWindowText(labelHandle, text);

In this example, the GetAccessibleObjectFromWindow function is used to retrieve the accessibility object associated with a window handle. The AsHyperText method is then used to retrieve the text content of the object as a hyperlinked string, which is then displayed in a label control.

Example 2:

// Retrieve an accessibility object
IAccessible* obj = GetFocusedAccessibleObject();

// Retrieve the hyperlinked text content of the object
BSTR text = AccessibleWrap::AsHyperText(obj);

// Prompt the user to follow the link
int result = MessageBox(NULL, text, L"Accessibility Link", MB_OKCANCEL);

// If the user clicks OK, open the link in a web browser
if (result == IDOK) {
  ShellExecute(NULL, L"open", text, NULL, NULL, SW_SHOWNORMAL);
}

In this example, the GetFocusedAccessibleObject function is used to retrieve the accessibility object associated with the currently focused component. The AsHyperText method is then used to retrieve the text content of the object as a hyperlinked string, which is then displayed to the user in a message box. If the user clicks OK, the link is opened in a web browser using the ShellExecute function. Based on the syntax and method names, AccessibleWrap is likely a custom library developed by the author of the code examples.
