user interface - Put a label beside a text entry in python gtk -


so i'm trying build pretty basic gui using python gtk, i'm getting frustrated quickly. how put label beside text entry? how can make entry smaller? button smaller? i'm going have add more entries , take them in @ once process information, , don't need them fill window... thanks.

#!/usr/bin/python #-*- coding: iso-8859-1 -* import pygtk pygtk.require('2.0') import gtk   class text_box:     #callback function, data arguments ignored     def hello(self, widget, entry):         entry_text = self.entry.get_text()         print("entry contents: ".format(entry_text))       def delete_event(self, widget, event, data=none):         #return of false deletes event, true keeps         print("delete occurred")         return false      def submit(self, button):         try:             input = self.entry.get_text()             print(float(input))             return input         except valueerror:             print("this not number...")             self.md = gtk.messagedialog(none, gtk.dialog_destroy_with_parent, gtk.message_error, gtk.buttons_close, "this not number")             self.md.set_position(gtk.win_pos_center)             self.md.run()             self.md.destroy()       def enter(self, button):         try:             input = self.entry.get_text()             input = float(input)             print(input)             return input         except valueerror:             self.md = gtk.messagedialog(none, gtk.dialog_destroy_with_parent, gtk.message_error, gtk.buttons_close, "this not number")             self.md.run()             self.md.destroy()             print("this not number...")        #another callback     def destroy(self, widget, data=none):         gtk.main_quit()      def __init__(self):          self.fix = gtk.fixed()          #create new window         self.window = gtk.window(gtk.window_toplevel)         self.window.set_size_request(500, 500)         self.window.set_title("powder application")         self.window.set_position(gtk.win_pos_center)         vbox = gtk.vbox(false,0)         self.window.add(vbox)         vbox.show()          #when window given delete_event, close         self.window.connect("delete_event", self.delete_event)          #connect "destroy" event signal handler         #occurs gtk_widget_destroy() or false in delete_event         self.window.connect("destroy", self.destroy)          #sets border width of window         self.window.set_border_width(10)          #creates button         self.button = gtk.button("submit")         #self.button.connect("clicked", self.hello, none)          #submit data in window on click         self.button.connect_object("clicked", self.submit, self.window)           #make entry box         self.entry = gtk.entry()         self.label = gtk.label("powder density")         vbox.pack_start(self.label, false, false, 0)         self.label.show()         self.entry.set_max_length(20)         self.entry.select_region(0, len(self.entry.get_text()))         #self.entry.connect("activate", self.hello, self.entry)         self.entry.connect_object("activate", self.enter, self.window)         vbox.pack_start(self.entry, false, false, 0)         self.entry.show()          #this packs button , entry window         #self.window.add(self.button)         #self.window.add(self.entry)          #hbox = gtk.hbox(false, 0)         #vbox.add(hbox)         #hbox.show()          #the final step display newly created widget.         vbox.pack_start(self.button, false, false, 00)         self.button.show()          #and window         self.window.show()      def main(self):         #all pygtk apps must have gtk.main().  control ends here         #and waits event occur          gtk.main()         return 0   #if program run, create gui instance , show if __name__ == "__main__":     hello = text_box()     hello.main()

try using table , add table window using:

table=gtk.table(1,4,true) table.attach(label,0,1,0,1) table.attach(entry,1,3,0,1) table.attach(button,3,4,0,1) window.add(table) window.show_all()

this displays label beside text box, button beside it
