Article
02/22/2024

Gets or sets the InkRenderer object that is used to draw ink.

This property is read/write.

Syntax

HRESULT get_Renderer(
  IInkRenderer **CurrentInkRenderer
);

Parameters

CurrentInkRenderer

Return value

None

Remarks

When handling certain window messages, changing the Renderer associated with the InkCollector can cause a reentrant function call, generating unexpected results. For example, changing to a different Renderer or modifying its transforms within a message handler can result in a reentrant call. This affects the following messages: WM_ACTIVATE, WM_ACTIVATEAPP, WM_NCACTIVATE, WM_PAINT; WM_SYSCOMMAND if wParam is set to SC_HOTKEY or SC_TASKLIST; and WM_SYSKEYDOWN (when processing Alt-Tab or Alt-Esc key combinations). It is an issue with single-threaded apartment model applications.
