Pygtk color for drag_highlight

Question

I'm trying to change the highlight color for a gtk.EventBox. It has a certain background color, and I want to draw a line around it with its complementary color. I have found drag_highlight, which draws a line around the widget, but I have not figured out how to change the color: it's always black. Any ideas?

Answer 1

To make the line around the EventBox, it is possible to put it into the Frame or another EventBox (in this case it is possible to set the width of the "border"), here is how it looks:

And here is the code (it is a modified EventBox example):

#!/usr/bin/env python

# example eventbox.py

import pygtk
pygtk.require('2.0')
import gtk

class EventBoxExample:
    def __init__(self):
        window = gtk.Window(gtk.WINDOW_TOPLEVEL)
        window.set_title("Event Box")
        window.connect("destroy", lambda w: gtk.main_quit())
        window.set_border_width(10)

        # Create an EventBox and add it to our toplevel window
        frame = gtk.EventBox() # gtk.Frame()
        window.add(frame)
        frame.show()
        frame.set_border_width(2)
        frame.modify_bg(gtk.STATE_NORMAL,
                            frame.get_colormap().alloc_color("blue"))

        event_box = gtk.EventBox()
        frame.add(event_box)
        event_box.set_border_width(10)
        event_box.show()

        # Create a long label
        label = gtk.Label("Click here to quit, quit, quit, quit, quit")
        event_box.add(label)
        label.show()

        # Clip it short.
        label.set_size_request(110, 20)

        # And bind an action to it
        event_box.set_events(gtk.gdk.BUTTON_PRESS_MASK)
        event_box.connect("button_press_event", lambda w,e: gtk.main_quit())

        # More things you need an X window for ...
        event_box.realize()
        event_box.window.set_cursor(gtk.gdk.Cursor(gtk.gdk.HAND1))

        # Set background color to green
        event_box.modify_bg(gtk.STATE_NORMAL,
                            event_box.get_colormap().alloc_color("green"))

        window.show()

def main():
    gtk.main()
    return 0

if __name__ == "__main__":
    EventBoxExample()
    main()
