### NAME

Tk_HandleEvent — window system 行事の為の行事操作子を起動する　 invoke event handlers for window system events

### SYNOPSIS

#include <tk.h>
Tk_HandleEvent(eventPtr)

### 引数 ARGUMENTS

XEvent *eventPtr (入力in)
  適切な取っ手を発送すべき X 行事への指示子｡構造の全ての未使用の欄は零に設定されることは重要である｡　 Pointer to X event to dispatch to relevant handler(s). It is important that all unused fields of the structure be set to zero.

### 説明 DESCRIPTION

Tk_HandleEvent は窓の行事を扱う低水準手続函数である｡それは Tcl_ServiceEvent (及び Tcl_DoOneEvent から間接に)と､他の幾つかの場合に Tk.内部から呼ばれる｡それは eventPtr に合致するどの窓の行事処理機能(Tk_CreateEventHandler の呼出しによって作成された)にも呼戻しを作成して戻る｡ Tk 行事待ち行列をすり抜ける応用譜と､後に Tcl_ServiceEvent が続く Tcl_QueueEvent 呼出の代わりに直接 Tk_HandleEvent を呼ぶ応用譜には便利である｡ Tk_HandleEvent is a lower-level procedure that deals with window events. It is called by Tcl_ServiceEvent (and indirectly by Tcl_DoOneEvent), and in a few other cases within Tk. It makes callbacks to any window event handlers (created by calls to Tk_CreateEventHandler) that match eventPtr and then returns. In some cases it may be useful for an application to bypass the Tk event queue and call Tk_HandleEvent directly instead of calling Tcl_QueueEvent followed by Tcl_ServiceEvent.

この手続函数は再起的に起動もされる｡譬えば､ Tk_HandleEvent.に呼出された処理機能から再起的にTk_HandleEvent を起動することが可能である｡この種の操作は､通知譜が通知窓を出現させ､使用者が何か別のことをする前に通知譜内の釦を軽叩することを望む場合等の排他的専用状況には便利である｡ This procedure may be invoked recursively. For example, it is possible to invoke Tk_HandleEvent recursively from a handler called by Tk_HandleEvent. This sort of operation is useful in some modal situations, such as when a notifier has been popped up and an application wishes to wait for the user to click a button in the notifier before doing anything else.
