问题
I have a WinForms gui application which has a number of areas to it which I'd like to custom-draw some graphics. These areas would contain controls and be resizeable. I'm currently thinking of inheriting from a TableLayoutPanel and handling onpaint messages.
Does this sound like a good way to go or are there other/better options?
回答1:
Any Windows Forms control has a Paint event, you don't have to derive your own class. But sure, you can, it helps partitioning the code. Just pick a base class that already provides most of what you need. Set the DoubleBuffered property to true in the constructor and override OnPaint.
