    <p>I wrote a simple program importing Tkinter just to play with Radio Buttons. I find that I'm getting errors in very, very weird places. </p> <pre><code> from Tkinter import * class Application (Frame): def __init__(self, master): Frame.__init__(self, master) self.grid() self.create_widgets() def create_widgets(self): Label(self, text = "Select the last book you read.").grid (row = 0, column = 0, sticky = W) self.choice = StringVar() Radiobutton (self,text = "Nausea by Jean-Paul Sartre",variable = self.choice, value = "Wake up. This is a dream. This is all only a test of the emergency broadcasting system.", command = self.update_text).grid (row = 2, column = 1, sticky = W) Radiobutton (self, text = "Infinite Jest by David Foster Wallace", variable = self.choice, value = "Because an adult borne without the volition to choose the thoughts that he thinks, is going to get hosed ;)", command = self.update_text).grid (row = 3, column = 1, sticky = W) Radiobutton (self, text = "Cat's Cradle by Kurt Vonnegut", variable = self.choice, value = " \"Here we are, trapped in the amber of the moment. There is no why!\" ", command = self.update_text.grid (row = 4, column = 1, sticky = W) self.txt_display = Text (self, width = 40, height = 5, wrap = WORD) self.txt_display.grid (row = 6, column = 0, sticky = W) #There is only one choice value - self.choice. That can be "printed." def update_text(self): message = self.choice.get() self.txt_display.delete (0.0, END) self.txt_display.insert (0.0, message) # The Main root = Tk() root.title ("The Book Critic One") root.geometry ("400x400") app = Application (root) root.mainloop() </code></pre> <p>I seem to be getting errors in very odd places. One came in the "=" sign in the Label attribution and when I changed it to == when i was playing around, the next one came in the variable part of the RadioButton attributes. </p> <p>Any help would be greatly appreciated. Won't be able to respond immediately as I have to leave to work in a bit, but if you do spot where the bugs are, please let me know.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
