Mono 上的 C# 用户控制？

Question

I'm porting a Windows Form C# application in Linux using mono. I'm solving a lot of problems but now I don't know what I need to do.

I can't use the User Control on linux.

I have used many user controls as container with some control (each User Control is a button bar with some big button) that I display when I need.

When I execute the application on linux, it does not work.

All of my User Controls (container) become transparent. If I move the mouse I see that there is a button because the mouse cursor changes and the button responds to clicks, but it is transparent.

Answer 1

The problem was not in the User Controls but in their function paint override. I created an override that did set some parameters of the control (size of text, syle of text) and then drew the base paint

public override paint(...) {
    //...instruction...
    base.paint(...);
}

This created problems. Now I removed all instruction and it works. For me this is enough. Any changes to the control do otherwise.
