Member Function Documentation

ActivateContext()

void FWindowsTextInputMethodSystem::ActivateContext ( const TSharedRef< ITextInputMethodContext > &  Context )

overridevirtual

Activates the provided context. Editable text should call this method when keyboard focus is received.

Parameters

Context

The context to be activated.

Implements ITextInputMethodSystem.

ApplyDefaults()

void FWindowsTextInputMethodSystem::ApplyDefaults ( const TSharedRef< FGenericWindow > &  InWindow )

overridevirtual

Called when a window is first created to allow the text input system to apply any default settings

Implements ITextInputMethodSystem.

DeactivateContext()

void FWindowsTextInputMethodSystem::DeactivateContext ( const TSharedRef< ITextInputMethodContext > &  Context )

overridevirtual

Deactivates the provided context. Editable text should call this method when keyboard focus is lost.

Parameters

Context

The context to be activated.

Implements ITextInputMethodSystem.

Initialize()

bool FWindowsTextInputMethodSystem::Initialize

(

)

IsActiveContext()

bool FWindowsTextInputMethodSystem::IsActiveContext ( const TSharedRef< ITextInputMethodContext > &  Context ) const

overridevirtual

Test to see whether the provided context is the currently active context

Parameters

Context

The context to be checked.

Returns

True if the context is active, false otherwise

Implements ITextInputMethodSystem.

ProcessMessage()

int32 FWindowsTextInputMethodSystem::ProcessMessage	(	HWND	hwnd,
		uint32	msg,
		WPARAM	wParam,
		LPARAM	lParam
	)

RegisterContext()

TSharedPtr< ITextInputMethodChangeNotifier > FWindowsTextInputMethodSystem::RegisterContext ( const TSharedRef< ITextInputMethodContext > &  Context )

overridevirtual

Registers an implemented context interface object with the system to receive callbacks and provides an implemented notifier interface object. Editable text should call this method after constructing an implemented context interface object.

Parameters

Context

UnregisterContext()

void FWindowsTextInputMethodSystem::UnregisterContext ( const TSharedRef< ITextInputMethodContext > &  Context )

overridevirtual

Unregisters an implemented context interface object with the system. Editable text should call this method before destroying an implemented context interface object.

Parameters

Context

The implemented context interface object to be unregistered.

Implements ITextInputMethodSystem.
