WM_IME_SETCONTEXT

The WM_IME_SETCONTEXT message is sent to an application when a window of the application is activated. If the application has created an IME window, it should call the ImmIsUIMessage function. Otherwise, it should pass this message to the DefWindowProc function.

fSet = (BOOL) wParam;
iShow = (DWORD) lParam;
 

Parameters

fSet

Active flag. If TRUE, the input context is active. If FALSE, the context is inactive.

iShow

Show flags. This parameter can be a combination of the following values.

Value	Description
ISC_SHOWUICOMPOSITIONWINDOW	Shows the composition window by UI window.
ISC_SHOWUIGUIDWINDOW	Shows the guide window by UI window
ISC_SHOWUISOFTKBD	Shows the soft keyboard by UI window
ISC_SHOWUICANDIDATEWINDOW	Shows the candidate window of Index 0 by UI window.
ISC_SHOWUICANDIDATEWINDOW << 1	Shows the candidate window of Index 1 by UI window.
ISC_SHOWUICANDIDATEWINDOW << 2	Shows the candidate window of Index 2 by UI window.
ISC_SHOWUICANDIDATEWINDOW << 3	Shows the candidate window of Index 3 by UI window.

If the application draws the composition window, the default IME window does not need to show its composition window. In this case, the application must clear the ISC_SHOWUICOMPOSITIONWINDOW value from the lParam parameter before passing the message to the DefWindowProc or ImmIsUIMessage functions.

Return Values

Returns the value returned by DefWindowProc or ImmIsUIMessage.
