    <p>Just for other's benefit who find this question I'm attaching my neer final test code which uses picture in picture/magnifying glass zooming. Its basically just an alteration to what samplebias already posted. It's also very cool to see as well :).</p> <p>As I said before, if you're using this script on linux don't forget to change the MouseWheel event to Button-4 and Button-5. And you obviously need to insert a .JPG path where it says "INSERT JPG FILE PATH".</p> <pre><code>from Tkinter import * import Image, ImageTk class LoadImage: def __init__(self,root): frame = Frame(root) self.canvas = Canvas(frame,width=900,height=900) self.canvas.pack() frame.pack() File = "INSERT JPG FILE PATH" self.orig_img = Image.open(File) self.img = ImageTk.PhotoImage(self.orig_img) self.canvas.create_image(0,0,image=self.img, anchor="nw") self.zoomcycle = 0 self.zimg_id = None root.bind("&lt;MouseWheel&gt;",self.zoomer) self.canvas.bind("&lt;Motion&gt;",self.crop) def zoomer(self,event): if (event.delta &gt; 0): if self.zoomcycle != 4: self.zoomcycle += 1 elif (event.delta &lt; 0): if self.zoomcycle != 0: self.zoomcycle -= 1 self.crop(event) def crop(self,event): if self.zimg_id: self.canvas.delete(self.zimg_id) if (self.zoomcycle) != 0: x,y = event.x, event.y if self.zoomcycle == 1: tmp = self.orig_img.crop((x-45,y-30,x+45,y+30)) elif self.zoomcycle == 2: tmp = self.orig_img.crop((x-30,y-20,x+30,y+20)) elif self.zoomcycle == 3: tmp = self.orig_img.crop((x-15,y-10,x+15,y+10)) elif self.zoomcycle == 4: tmp = self.orig_img.crop((x-6,y-4,x+6,y+4)) size = 300,200 self.zimg = ImageTk.PhotoImage(tmp.resize(size)) self.zimg_id = self.canvas.create_image(event.x,event.y,image=self.zimg) if __name__ == '__main__': root = Tk() root.title("Crop Test") App = LoadImage(root) root.mainloop() </code></pre>

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.
