WPF TextBox从鼠标指针获取并设置插入符位置 [英] WPF TextBox obtain and set caret position from mouse pointer

问题描述

当我将鼠标悬停在TextBox上时，我试图根据鼠标坐标设置TextBox插入符号的位置. 我可以通过使用Mouse.GetPosition(this.MyTextBox)获得相对于TextBox的鼠标坐标，但是我需要帮助将这些坐标转换为插入符号位置. 任何帮助将不胜感激！

I am trying to set TextBox caret position according to the mouse coordinates when hovering over the TextBox. I can obtain the mouse coordinates relative to the TextBox by using Mouse.GetPosition(this.MyTextBox) but I need help translating those coordinates into the caret position. Any help would be greatly appreciated!

推荐答案

MyTextBox.CaptureMouse();
MyTextBox.CaretIndex = MyTextBox.GetCharacterIndexFromPoint(Mouse.GetPosition(MyTextBox), true);
