pygtk更改gtkHBox小部件的背景颜色 [英] pygtk change background color of gtkHBox widget

问题描述

我有一个GTK ui，它具有一个gtkVBox，该gtkVBox会在用户工作时动态添加gtkHbox包含的内容.

I have a GTK ui that has a gtkVBox that gets gtkHbox's containing content dynamically added to it as the user works.

用户界面越来越拥挤，很难说出组件属于哪个Hbox(它们重复).

The ui is getting crowded and it's difficult to tell what Hbox the components belong to (they repeat.)

我想更改gtkHboxes的背景颜色，以便每个颜色在较亮和较暗的颜色之间交替.

I would like to alter the background color of the gtkHboxes so it alternates between a lighter and darker color for each one.

基本上，我正在创建一个组合框的动态表，其中每行代表一个对象.现在我需要对行进行细分，因为它们非常安静且难以跟踪.

Basically, I'm creating a dynamic table of combo boxes where each row represents an object. Now I need to segment the rows since they are quiet complex and hard to follow.

谢谢， 戴夫.

推荐答案

根据

According to the docs, since hboxes "do not have an associated window", you can not directly modify the background color. The docs suggest to wrap it in and event box. This works quite well:

hbox = gtk.HBox()
eb = gtk.EventBox()     
eb.add(hbox)
eb.modify_bg(gtk.STATE_NORMAL, gtk.gdk.Color(red=65535))
