How to disable a Combobox in Tkinter?
combobox, python, tkinter
Solution
You want to use the `Combobox` option of `state='disabled'`.
There are three options for `state` as follows:
- `state='normal'` which is the fully functional `Combobox`.
- `state='readonly'` which is the `Combobox` with a value, but can't be changed (directly).
- `state='disabled'` which is where the `Combobox` cannot be interacted with.
Problem
Basically, I want to disable a certain Combobox, based on the value of another combobox. I couldn't find a answer to this question, maybe because it's very uncommon to do this to a Combobox. I have a code more or less as follow... ``` self.cBox1Var=tki.StringVar() self.cBox1=ttk.Combobox(self.mframe, width=16, textvariable=self.cBox1Var, state='readonly',values=['Text entry','Combo box','Check button']) self.cBox1.grid(row=0,column=1,sticky=tki.W) self.cBox1Var.set('Text entry') self.cBox1Var.bind("<<ComboboxSelected>>", lambda event, count=count: self.EnableDisableParamFields(event, count)) self.cBox2Var=tki.StringVar() self.cBox2=ttk.Combobox(self.mframe, width=16, textvariable=self.cBox2Var, state='readonly',values=['String','Integer','Float']) self.cBox2.grid(row=0,column=2,sticky=tki.W) self.cBox2Var.set('String') ``` ... ``` def EnableDisableParamFields(self, event, count): if self.cBox1Var.get()=='Combo box': #disable 'Entry format combo box' #disable "self.cBox2" else: #enable "self.cBox2" ``` Thanks in advance EDIT!!!! After persisting, found the answer, and it is quite simple.
