Recently, I want to create something that can draw flowcharts by myself, just like Microsoft Visio. ProgramI will draw a flowchart to show you some ideas ..

Create a small program, such as creating a flowchart,
Draw some boxes, circles, and text in a region,
Then use a line to connect. You can drag a box or something like this (the connected line also needs to be moved)
Finally, you need to save it as an image,
What solution should I use.
I thought about two solutions.
One is direct plotting.
The other is to use graphical components (just like the Delphi environment)

<I didn't say it was too detailed, mainly because it was a function like this>

Dev has flowchat

Create a specific data structure to describe different graphics, and then program with the concept of drawing.

Third-party control dxflowchart!

Haha. Thanks for the upstairs. Why can't I open csnd at home last weekend? To be honest, sometimes I have to say that csdn is so bad. For a while, either there is a problem or there is a problem there.
