如何在c＃GTK mono中将背景色设置为固定？

Question

I am new to C# Gtk in mono. I have made a window with two buttons with this code :

using Gtk;
using Gdk;

class FirstScreen : Gtk.Window
{

public FirstScreen() : base("Buttons")
{
    SetDefaultSize(250, 200);
    SetPosition(WindowPosition.Center);

    DeleteEvent += delegate { Application.Quit(); };

    Fixed fix = new Fixed();

    Button btn1 = new Button("Take Photo");

    Button btn2 = new Button("Take Video");

    Gdk.Color col = new Gdk.Color();
    Gdk.Color.Parse("red", ref col);
    fix.(StateType.Normal, col);

    fix.Put(btn1,30, 80);
    fix.Put(btn2, 130, 80);


    Add(fix);
    ShowAll();
}


public static void Main() 
{
    Application.Init();
    new FirstScreen();
    Application.Run();
}

}

I Want the Background color of the window or the fixed to be changed .How could we do that Please help?

Answer 1

By default Gtk.Fixed doesn't have its own Gdk.Window but draws on its parent window and doesn't draw any background. To have it draw a background, just tell it to create its own Gdk.Window :

fix.HasWindow = true;

That's all.

You would try use eventbox. And establish your object in box. For example:

eventbox.ModifyBg (StateType.Normal, new Gdk.Color (0, 0, 0));  //Zeros represent of (r,g,b)
