A table is useful to display data or information that is visible in form of rows and columns. The Tkinter.ttk module is used to drive a tree view and we use the tree view to make a table. Treeview refers to hierarchical representation. If you have any questions about my code, feel free to ask.In this section, we learn about the Python Tkinter table and we create a Tkinter table with the help of Treeview. If there is a more convenient solution feel free to comment. This is important for strings like '0005' which will return as 5 (integer) when you recall it from the treeview and you lose the leading zeros. This way I keep the real data I inserted into the treeView. I use the treeview just to show the data and a seperate dictionary to save the data, by using the child-id (returned by insert) as key. Self.myFont = tkFont.Font(self, "Calibri", 12) Self.myFont is defined as follows: import tkinter.font as tkFont So I use a mapping list which is stored as self.indexlist. My headings for the treeView are stored in self.attributeList but the data comes from a database, which has way more columns I want to show. ("" + str(curMainWindowWidth) + "x" + str(curMainWindowHeight)) New_length = (str(item))įor idx, item in enumerate(self.attributeList): Max_colum_widths = * len(self.indexlist)įor idx, rowIdx in enumerate(self.indexlist): # save the data in it's original types in a dictionary Insert_ID = ('', 'end', text=count, values=adding_string) ![]() Setting the size of the mainWindow to the stored valuesĪnd here is my code: def reloadTreeViewData(self):ĬurMainWindowHeight = _height()ĬurMainWindowWidth = _width().Calling the update function on my mainWindow (not sure if this is needed).Set the width of each column depending on the max length of an entry (by using measure).I read the current size of my mainWindow.I don't find any solution to set the width as a constant number.Īfter searching for over a week now, I stumbled upon a very easy way to do the 'magic'. I looked up some documents and search for this question.And define the width and height to constraint the Treeview. Define a frame to be the Treeview parent.I can't see my buttons, and I can't slide the horizontal scrollbar. But the treeview is across my screen and the horizontal scrollbar also can't slide. My target is when I define a large width(for example: 3000) of some column, my treeview could show the data as I expected. Id_list, width_list, text_list is used to store columns information.ĭetail_info_list is to store the data showed in the Treeview. Tree_id(row = 0, column = 0, sticky = NSEW) Tree_view.heading(id_list, text = text_list) Tree_lumn(id_list, width = width_list, anchor = CENTER) Tree_view = Treeview(frame, height = 33, selectmode = "extended") Here is my main code : frame = Frame(self.master, width = 1845, height = 670) (The default width is the summation of all columns' width) My question is, How can I set the width of the Treeview. I found out the width of the treeview only depends on the width of columns. Specifically, 49 columns data in a treeview. Recently, I use tkinter TreeView to show many columns in Python. ![]()
