What do I use in place of `ttk.Labelframe`? about customtkinter HOT 8 CLOSED

It's a bug or a missing feature in customtkinter. So when you place a CTk element onto something I need to get the background color of the element on which the CTk element was placed. Then I can set the bg_colour of the CTk element to the bg color of the master, so that I can draw rounded corners. The rounded corners are just circles on a tkinter.Canvas which has the same bg color as the master on which the CTk element was placed so that you don't see the canvas and just the circles and rects on the canvas.

And at the moment I detect if the master widget as a tkinter widget, and if so, I read the bg color of the mastere by doing .cget("bg"). But that doesn't work on ttk widgets because they don't have a bg attribute, they have a style.

So I somehow need to get the style of the ttk element and from the style I can get the bg color, but I don't now if this will work. For now I will change the code so that it doesn't throw an error on ttk elements and just set the bg to black by default on ttk widgets . Then you have can set the bg_color attribute manually to the correct color if you want...

from customtkinter.

So the CTk widgets now work on ttk.Frame, ttk.LabelFrame and ttk.Notebook. But only with the default color:

Program: test/test_ttk_frames.py

If the color gets changed by a ttk style, then you have to manually set the bg_color attribute of all CTk widgets on them to the new color, it's not possible to do this automatically for me at the moment.

But overall it would prefer to use a CTkFrame instead of a ttk.Labelframe because it's more convenient and you can also place a label at the top as I did in test/test_ttk_frames.py and add a border if you want.

Its a bug? Tkinter sure as hell has a lot of bugs to be called stable and mature

from customtkinter.

bg_color = tkinter.ttk.Style().lookup(".", "background")

from customtkinter.

I now, actually, what I do to get the bg color of the master widget is this on ttk widgets:

ttk_style = ttk.Style()
return ttk_style.lookup(self.master.winfo_class(), 'background')

customtkinter/widgets/customtkinter_button.py line 144

The problem is, that I cannot now if the style gets changed afterwards in the runtime of the program. Then I would have to change the bg_color of the ctk button again. On tkinter widgets, I do this by overwriting the configure method of the master, so that all the ctk childs on that master get notified when the bg color of the master gets configured. But with ttk i can't do this, because the bg change of the master doesn't happen through the configure method, but a style change. And there is nothing like a style change event or something similar.

And there is nothing like a style change event

There is <<ThemeChanged>>, although I am not sure you need it.

from customtkinter.

ThemeChanged only gets called if you load a new theme, but there is no event for individual theme modifications on widgets, so I will close this one.

@TomSchimansky There's also <Configure> maybe that's what you are looking for?
