Text Services Manager Routines for Components

Opening Floating Utility Windows

In conjunction with the Process Manager, the Text Services Manager maintains the floating window service, whose windows occupy a special layer called the floating window service layer. See Figure 7-7 on page 7-14.

The Text Services Manager uses the floating window service to provide a standard floating input window when needed. Text service components can use the service to create, close, and find floating windows used for various other user-interface purposes. You can manipulate the service windows with these calls:

• The NewServiceWindow function lets you open a floating window in front of the current application.
• The CloseServiceWindow function lets you close a previously allocated floating window.
• The GetFrontServiceWindow function helps you find out which is the frontmost window in the floating window service layer.
• The FindServiceWindow function helps you find out which part of a text service component's floating window a mouse-down event has occurred in.

Client applications

These calls may be made by client applications also. See the following description of NewServiceWindow for special instructions for client applications.
