视图中插入文本块的编程方法

在一般应用软件中，文本输入是必不可少的。如何让文本输入像画线、画圆、画椭圆一样简单方便，实现在视图中插入文本块？可将输入的文本看成是一个文本块，或者说是一个矩形，在矩形中完成文本的输入、修改、换行等操作。这样，工作就转化为在视图中插入一个矩形，编程并让该矩形响应鼠标和键盘消息，从而实现文本块中文本的输入及各项操作。具体通过VC＋＋中文档、视图之间数据交换和各自职能的特点以及C＋＋中面向对象的技术^1,2]，实现了在视图中插入文本块的方法。这里的文本块如其它的图形对象一样，可以选择、可以移动、可以修改、可以删除。最后给出了实现结果的图片。

The Method of Programming on Inserting Text-block in the View

Text_inputting is necessary in general applications. It's the work of the paper to make text_inputting as convenient as drawing a line or drawing a circle. The purpose of the paper is to demonstrate an easy method of inputting_text_block in the view.Viewing the inputted text as a text block or a rectangle, you can realize the operation of input_text, modify_text, change_text, pedestrian of the text, etc. So the work was changed to insert a text_block in the view. With proper programming,you can make the rectangle respond to the message of the mouse or keyboard.The paper realized the method of inserting the text_block in the view with the feature of data exchange and operator of each other in document and view and object_orientation in C++. The text block can be selected, moved and deleted like the other object of picture. The result picture is presented in the end of the paper.
