could not initiate slide show manager about kburns-slideshow

[danya-gharbieh]

yeah sure I added a button on my GUI then when we press on the button your slideshow app will open as shown in the code below:

slideshow_btn = tk.Button(self.frame, text="Slideshow editor", font=('arial', 16), width=20, height=10
, command=self.slideShowApp)

def slideShowApp(self):
app3 = App()
app3.grab_set()

this will open your slideshow app ,
btw I fixed the above error by update app.py file parameter from "class App(tk.TK)" to "class App(tk.Toplevel)"
but I have another error so when slideshow app appears and then i press add slide below error appears:

Exception in Tkinter callback

any idea about this error ?

Could you explain how you integrated the slideshow app in your application, e.g. by showing some code?

[Trekky12]

Actually I didn't test embedding the application in another application. Let me look into it.
Could you provide a small running example code to show the problem? You don't need to provide your application but a small runnable example.

I think the error message has to do with the transition folder. Did you have the folder in the correct location?

[danya-gharbieh]

okay sure

kindly find a small runnable application in this link : https://drive.google.com/file/d/123EGl2Htv20XneM8qFh1WGJoyteNz5tl/view?usp=sharing

Thanks in advanced

Hey @danya-gharbieh,

I've tested your code and you should move the folder "transitions" from the subfolder "kburns" to the root directory of the application. This solves the error messages.
The reason for that is that the possible transitions are searched from this folder which is referenced from the root directory (os.getcwd()):

def getTransitions(self):
        return [package_name for importer, package_name, _ in pkgutil.iter_modules([os.path.join(os.getcwd(), "transitions")])]

[danya-gharbieh]

moving the folder works thanks a lot ,
