Bind a reset button to a function that turns it from DISABLED to NORMAL when multiple Combo Boxes are clicked #504
-
|
Hi, Im trying to programme a reset buttons such that, if three Combo Boxes are filled with values, different from their initial 'Select' option, then the reset button changes from DISABLED to NORMAL. In my current code, I've to enable to reset button when return is hit...but I've not managed to get that to work either. So would preferably like it to enable when the three Combo Boxes are filled Please see my code attached. If theres any more information or I haven't made a lot of sense, please let me know! `import tkinter.messagebox customtkinter.set_appearance_mode("System") # Modes: "System" (standard), "Dark", "Light" class HomePage(customtkinter.CTk): if name == "main": |

@amanashraf Here is your modified code with the solution you requested: import customtkinter
import tkinter
customtkinter.set_appearance_mode("System") # Modes: "System" (standard), "Dark", "Light"
customtkinter.set_default_color_theme("blue") # Themes: "blue" (standard), "green", "dark-blue"
class HomePage(customtkinter.CTk):
WIDTH = 1000
HEIGHT = 750
def __init__(self):
super().__init__()
self.title("Movie/Series Selector")
self.geometry(f"{HomePage.WIDTH}x{HomePage.HEIGHT}")

self.combobox_1 = customtkinter.CTkComboBox(master=self.frame_left,

text_font = ("Roboto Medium",20),

self.resetButton.configure(state=tkinter.NORMAL) ### Enable the reset button if the three combobox have values other than select
else:
self.resetButton.configure(state=tkinter.DISABLED) ### Disable the reset button if any of the three combobox have default Select value
def search(self):

SorM = self.combobox_3.get()
print(time, service, SorM)
def resetClick(self):
self.combobox_1.set("Select")
self.combobox_2.set("Select")
self.combobox_3.set("Select")
self.disable_enable(None) ### Make the button disabled again after resetting
def searchAgain(self):
pass #will create this later
def switchButton(self):
self.resetButton['state']=tkinter.NORMAL
self.nextResultButton['state']=tkinter.NORMAL
def on_closing(self, event=0):
self.destroy()
def start(self):
self.mainloop()
if __name__ == "__main__":
app = HomePage()
app.start()My changes with comments are given with I would recommend you to use CTkOptionMenu instead of CtkComboBox as there is no entry option in it. Here is the demo:Example_demo.mp4 |
