I am currently working on a project using Python and tkinter.
The problem is that I don't know what's the proper way to display multiple windows, or screens, I don't know how to call them. Let me explain better.
When the application starts the login screen appears. After that, if I click register, I want to go to the register screen, but I don't want it to be a separate window (I don't want to have 2 windows displayed at the same time), but rather another window with different content ?!
How should I handle properly this situation? Create a second window using Toplevel and hiding the first (can I do that?) or changing the widgets of the first?
Code I've written so far
You can do that- just call window.withdraw() on the Toplevel you need to hide after creating a new Toplevel. Changing the widgets in the first is also an option- if you like, you could always try a Notebook widget and disable manual flipping or just put each "screen" in a frame and grid_ or pack_forget them to remove them from the window.

I don't know How structure the GUI of my program...
I don't have big experience with GUI programming, i know all the widgets, the
geometry managers, the "object-oriented" method in Tkinter, but i don't understand
how combine all this things...
I want to create a program with an image in background where there is a button and if i press this button i switch in another page and the button disappears
Like this : https://moqups.com/iampirla#gmail.com/wyM7CyET/p:a80e8d902
How i can structure my code to do this?
You could use pack_forget() this removes the widget although allows you to use it later if you wish. You could do the first page and then use some code like below. To clear the page. This could then reference the next thing you wish to do using in this example question().
def answred():
nameLabel.pack_forget()
nameEntry.pack_forget()
nameButton.pack_forget()
classQuestion.pack_forget()
button1.pack_forget()
button2.pack_forget()
button3.pack_forget()
question()
You could this but not remove the background widgets
Pressing command-H in OSX immediately hides the active window. How do I achieve the same effect, programmatically, from Python? Specifically, I'd like to find a particular window that my application creates and then be able to show & hide it programmatically.
I already know how to do this with pywin32 but I'm afraid my expertise there doesn't quite cover OSX as well.
If it helps, the window in question is one created by pygame. I know that pygame has pygame.display.iconify() but that doesn't satisfy my requirements - the window doesn't disappear immediately, but rather the disappearance is animated, and there's no corresponding "uniconify" function that I can find.
Well, this ended up working. When I want to hide the window, I do pygame.display.quit() and make my code properly handle not having a display. When I want to show it, I do pygame.display.set_mode(...) with the former resolution.
The net effect is that of hiding & showing the window. Unfortunately the window gets created in a different spot than where it started, and although apparently you can tell SDL to create the window in a particular spot, I haven't been able to find a way to get the window's location...
I want to embed a window into another window, kind of like this:
EDIT: Screenshots deleted, sorry!
That is a wingdows program and was not made with GTK tough.
I tried using plugs and sockets, but apparently I can't put a gtk.Window (a toplevel window) on a plug.
Is it possible? If so, how? If not, what do you think I should do instead?
gtk.Window is derived from gtk.Bin, so it can only contain one single child. This again can be used in the following way:
Load both windows (e.g. from Glade files)
Remove the child from the second window, but save a reference to the child
Add the child somewhere in the first window
The second step would look like this:
childWidget = secondWindow.get_child()
secondWindow.remove(childWidget)
I'm using this approach to add plugin windows as tabs in one of my PyGTK applications. That means main window and plugins can be designed separately in Glade, and also implemented independently. Of course you're free to add the child widget anywhere you want.
I'm working on a project using Tkinter and Python. In order to have native theming and to take advantage of the new widgets I'm using ttk in Python 2.6. My problem is how to allow the user to scroll through the tabs in the notebook widget (a la firefox). Plus, I need a part in the right edge of the tabs for a close button. The frame for the active tab would need to fill the available horizontal space (including under the scroll arrows).
I thought I could do this using the Place geometry manager, but I was wondering if there was a better way? The ttk python docs don't have any methods to deal with this that I could see.
Edit: looks like there are difficulties for even trying to implement this using place. For one, I'd still need the tabs to scroll and the active panel to stay in the one place.
The notebook widget doesn't do scrolling of tabs (or multiple layers of them either) because the developer doesn't believe that they make for a good GUI. I can see his point; such GUIs tend to suck. The best workaround I've seen is to have a panel on the side that allows the selection of which pane to display. You can then apply tricks to that panel to manage the amount of information there (e.g., by making it a treeview widget and holding the info hierarchically, much like most email clients handle mail folders; treeview widgets are scrollable).
I've never used these widgets so I have no idea how possible this is, but what I would try is something akin to the grid_remove() method. If you can move the tabs to an invisible widget, or just make them invisible without losing content, that's what I'd look for/try.
I would like to create an application that has 3-4 frames (or windows) where each frame is attached/positioned to a side of the screen (like a task bar). When a frame is inactive I would like it to auto hide (just like the Windows task bar does; or the dock in OSX). When I move my mouse pointer to the position on the edge of the screen where the frame is hidden, I would like it to come back into focus.
The application is written in Python (using wxPython for the basic GUI aspects). Does anyone know how to do this in Python? I'm guessing it's probably OS dependent? If so, I'd like to focus on Windows first.
I don't do GUI programming very often so my apologies if this makes no sense at all.
As far as I know, there's nothing built in for this.
When the window is hidden, do you want it completely invisible or can a border of a few pixels be showing? That would be an easy way to get a mouse hover event. Otherwise you might have to use something like pyHook to get system-wide mouse events to know when to expand your window.
The events EVT_ENTER_WINDOW and EVT_LEAVE_WINDOW might also be useful here to know when the user has entered/left the window so you can expand/collapse it.
Expanding/collapsing can just be done by showing/hiding windows or resizing them. Standard window functions, nothing fancy.
By the way, you might want to use wx.ClientDisplayRect to figure out where to position your window. That will give you a rectangle of the desktop that does NOT include the task bar or any other toolbars the user has, assuming you want to avoid overlapping with those things.
Personally, I would combine the EVT_ENTER_WINDOW and EVT_LEAVE_WINDOW that FogleBird mentioned with a wx.Timer. Then whenever it the frame or dialog is inactive for x seconds, you would just call its Hide() method.
I think you could easily just make a window that is the same size as the desktop then do some while looping for an inactivity variable based on mouse position, then thread off a timer for loop for the 4 inactivity variables. I'd personally design it so that when they reach 0 from 15, they change size and position to become tabular and create a button on them to reactivate. lots of technical work on this one, but easily done if you figure it out
