vanilla Window opening 2nd Window

Hi, I have a vanilla
Windowthat calls another
Buttonis pressed (for example, to edit preferences).
Is it better / preferred / more "canonical" to initialize and open the second
Windowonce (and use the button only to run
.hide()), or to initialize and open a new second
Window(and close it completely) when the button is pressed?
A couple of examples to show what I mean below.
__init__; button shows/closes
from prefWindow import PrefWindow class MainWindow: def __init__(self): self.w = Window((200, 200)) self.w.prefButton = Button((10, 10, -10, 20), "Open Pref", callback=self.prefCB) self.prefOpened = False self.prefWindow = PrefWindow() self.prefWindow.w.open() self.prefWindow.w.hide() def prefCB(self, sender): if self.prefOpened: self.prefWindow.hide() else: self.prefWindow.w.show() self.prefOpened = !self.prefOpened
B) Button initializes new second
from prefWindow import PrefWindow class MainWindow: def __init__(self): self.w = Window((200, 200)) self.w.prefButton = Button((10, 10, -10, 20), "Open Pref", callback=self.prefCB) self.prefOpened = False def prefCB(self, sender): if self.prefOpened: self.prefWindow.w.close() else: self.prefWindow = PrefWindow() self.prefWindow.w.open() self.prefOpened = !self.prefOpened
I've gotten both versions to work, so I'm just wondering if there's one way that's preferred. Thanks!
Its depends on what you would like to achieve. But take note that a window can be closed in different ways,
⌘ + wor the red left top button... where you are not able to set the
Also you can not reopen a closed window. An other option is to overwrite the
closecallback in the window class used in the
vanilla.Windowobject and just order out instead of closing the window.
@frederik Good points, thanks. I was only using the
prefOpenedflags as examples above.
I've been using the 2nd method (not using the flag, just initializing a new
PrefWindow()every time I need that window). But because you can't reopen a closed window, like you said, I make a new
PrefWindow()when the button is clicked. I'm just not sure if it's strange to be initializing all of the vanilla UI components over and over again?
I'm thinking of switching to the first option (initialize once, and use
hide()), but also not sure if it's weird to have a hidden window in the "background."
depending on what you’re trying to build, you might also consider using a vanilla
Drawer. they work like separate windows attached to the parent window.
fyi: a drawer is not advised anymore by the Human Interface guidelines.
I'm building something that has a main
Window, with a list of objects (using
vanilla.List), and when the user clicks on a button, a second
Window(or can be a
Sheet) opens, where they can input some preferences.
In my original thinking, the preference
Window"belongs" to the object being edited, so I would initialize it every time the user hits the button. I only want one preference
Windowto be open at a time, so I use a flag to make sure the user can't open another preference
And this is where I started thinking of just using
hide(). Since I only want one preference
Windowanyway, it seems kind of strange to have to initialize and open one at every button click, and maybe I should just make one preference
Windowthat's always open but is sometimes hidden. (In this case, the preference
Either way, I'm passing in data from the object to the pref
Window. In the first case, when initializing:
prefWindow = PrefWindow(some, data, here) prefWindow.w.open()
In the second case, I initialize with nothing and then have a method to update:
prefWindow = PrevWindow() ... prefWindow.update(some, data, here) prefWindow.w.show()
maybe the easiest way todo is use a subclass like RoboFont is using for some windows:
from mojo.UI import ShowHideWindow # a show hide window is a special window that disables the close callback and just hides the window on close. w = ShowHideWindow((100, 100)) w.open() # we close w.close() # and are able to open it again w.open() # this also works w.hide() w.show()
hope this helps to have only one instance of your window
Oh, that's a good one. Thanks @frederik!
