python gtk页面布局,gtk python网格调整大小

Following the official tutorials about containers.

I have the follwoing code

import gi

gi.require_version('Gtk', '3.0')

from gi.repository import Gtk

class MainWindow(Gtk.Window):

def __init__(self):

Gtk.Window.__init__(self, title="test")

grid = Gtk.Grid()

self.add(grid)

button1 = Gtk.Button(label="Button 1")

button2 = Gtk.Button(label="Button 2")

button3 = Gtk.Button(label="Button 3")

button4 = Gtk.Button(label="Button 4")

button5 = Gtk.Button(label="Button 5")

button6 = Gtk.Button(label="Button 6")

grid.add(button1)

grid.attach(button2, 1, 0, 2, 1)

grid.attach_next_to(button3, button1, Gtk.PositionType.BOTTOM, 1, 2)

grid.attach_next_to(button4, button3, Gtk.PositionType.RIGHT, 2, 1)

grid.attach(button5, 1, 2, 1, 1)

grid.attach_next_to(button6, button5, Gtk.PositionType.RIGHT, 1, 1)

win = MainWindow()

win.connect("destroy", Gtk.main_quit)

win.show_all()

Gtk.main()

All good when I run it

However if I resize it the grid won't resize with the main window.

Any pointers how to make the grid resize?

thanks

Set the buttons to expand. Example:

import gi

gi.require_version('Gtk', '3.0')

from gi.repository import Gtk

class MainWindow(Gtk.Window):

def __init__(self):

Gtk.Window.__init__(self, title="test")

grid = Gtk.Grid()

self.add(grid)

button1 = Gtk.Button(label="Button 1", expand = True)

button2 = Gtk.Button(label="Button 2", expand = True)

button3 = Gtk.Button(label="Button 3", expand = True)

button4 = Gtk.Button(label="Button 4", expand = True)

button5 = Gtk.Button(label="Button 5", expand = True)

button6 = Gtk.Button(label="Button 6", expand = True)

grid.add(button1)

grid.attach(button2, 1, 0, 2, 1)

grid.attach_next_to(button3, button1, Gtk.PositionType.BOTTOM, 1, 2)

grid.attach_next_to(button4, button3, Gtk.PositionType.RIGHT, 2, 1)

grid.attach(button5, 1, 2, 1, 1)

grid.attach_next_to(button6, button5, Gtk.PositionType.RIGHT, 1, 1)

win = MainWindow()

win.connect("destroy", Gtk.main_quit)

win.show_all()

Gtk.main()
