Static Control Default Message Processing
The window procedure for the predefined static control window class performs
default processing for all messages that the static control procedure does not
process. When the static control returns FALSE for any message, the predefined
window procedure checks the messages and carries out the default action
described in the following table. In the table, a text static control is a static
control with the style SS_LEFTNOWORDWRAP, SS_LEFT, SS_CENTER, SS_RIGHT, or
SS_SIMPLE.
