鼠标悬停提示-VC上实现解决办法

鼠标悬停提示-VC上实现
实现功能：
当鼠标移动过后，停在窗口的某个位置不动一定时间（100MS）后，在鼠标停止位置显示提示文字。提示文字代码已经写好，现求鼠标停止事件的判断代码

------解决方案--------------------
其实只要判断鼠标的move事件。当触发move事件时就把计时器初始化，否则就开始计时。这样就满足你的要求了

// CXInfoTip class interface
//
// DESCRIPTION
//
// This tooltip control implements:
//
// o An immediate popup tip window
// o Normal control tooltips
//
// The tip window can display an icon and multi-line
// tip text. Seperate multiple text lines with a '\n '.
// The tip window 's colors are derrived from
// system window, window text, and scroll bar colors.
//
// Create the control by calling the Create() method.
//
// To display immediate tips, call the Show() method.
// Call SetIcon() to set the icon used for immediate tips.
//
// Use AddTool() to add tool windows. RelayEvent() must
// be called from the parent windows 's PreTranslateMessage().
//
// Call SetShowDelay() to adjust the tip popup delay.
//
// Call SetFont() to change the tooltip text font. The default
// is the system default GUI font.
