突出显示行时设置cellrenderertext前景色 [英] Set cellrenderertext foreground color when a row is highlighted

问题描述

当我有一个 gtk.CellRendererText 时，我可以将它的前景颜色与其中一个树存储的列相关联，并将 foreground-set 属性设置为True，以更改该列中文本的颜色。但是，当选中具有彩色列的行时，其颜色消失，并且与任何选定单元格的颜色相同。如何选择颜色？

When I have a gtk.CellRendererText, I can associate its foreground color with one of the tree store's columns, and set the foreground-set attribute to True, to change the color of the text in that column. However, when the row with the colored column is selected, its color disappears, and is the same as any selected cell's color. How do I change the color when it's selected?

推荐答案

我有同样的问题，并尝试不同的替代方案后，使用标记属性而不是 text 属性解决了这个问题。请在下面找到适用于Ubuntu Maverick的示例：

I've had the same problem and, after trying different alternatives, using the markup property instead of the text property solved the problem. Please find below and example that works in Ubuntu Maverick:

#!/usr/bin/python                               
import gtk


class Application(object):
    def __init__(self):
        window = gtk.Window()

        model = gtk.TreeStore(str)
        model.append(None, row=('Normal row',))
        model.append(None, row=('<span foreground="red">Red row</span>',))

        treeview = gtk.TreeView(model)
        renderer = gtk.CellRendererText()
        column = gtk.TreeViewColumn('Column', renderer, markup=0)
        treeview.append_column(column)

        scrolled_window = gtk.ScrolledWindow()
        scrolled_window.add(treeview)

        window.add(scrolled_window)
        window.connect('destroy', lambda w: gtk.main_quit())

        window.show_all()


    def run(self):
        gtk.main()


if __name__ == '__main__':
    Application().run()

在一个更复杂的树状视图中，我正在处理多个列，当未选择该行时，标记属性似乎不起作用。无论如何，同时使用标记和前景属性似乎工作正常。

In a more complex treeview with the multiple columns that I'm working on, the markup property doesn't seem to work when the row isn't selected. Anyway, usage of both markup and foreground properties at the same time seems to work fine.
