[nonVCL] Subclassing eines Editfeldes - Problem

[sniper_w]

Zitat:

When a window loses the keyboard focus, the system sends the WM_KILLFOCUS message to the window. Your application should destroy the caret while processing this message by using the DestroyCaret function. The following code shows how to destroy a caret in a window that no longer has the keyboard focus.

case WM_KILLFOCUS:

// The window is losing the keyboard focus, so destroy the caret.

DestroyCaret();

break;
