Tk provides the tk.StringVar() to create objects that act like a string, but in order to assign or read a value we need to use the set() and get() methods. But when our application requires to both read the user input and write new text into the textbox very often, then it would be more suitable to link a variable. When a textbox is simply employed to receive a text entered by the user, then it will be enough to call the get() method to obtaint the text when we need it, as previously exposed. The select_present() method returns a boolean that indicates where there is a selection at all. Button ( text = "Get selection", command = get_selection ) S = "Last point clicked at x=%s y=%s" % (x, y)ġ) don't start a variable name with a capital letter, use those for class namesĢ) avoid variable names like i1, l, l1 and the likeģ) try to keep the tkinter name space with 'tk.'Īs your program gets larger, you and others will appreciate this.# Get the selection start and end indexesīutton = ttk. StartYInput = tk.Entry(plotRow, width=10)Ĭanvas = tk.Canvas(self._root, bg='white')Ĭid(column=0, row=1, sticky='nwes') StartXInput = tk.Entry(plotRow, width=10)ĭ1 = tk.Label(plotRow, text=' Start Y: ') x and y are used to specify the position to place the widget whereas width and height are used to alter the. place() method usually takes 4 arguments: x, y, width, and height. The best thing about place manager is you can place the widget anywhere within the widget. The place() is a layout manager in Tkinter just like pack() and grid(). Has no effect if the text fits entirely within the entry. Output: Method 2: By Using the place() layout manager. index ( index ) Shift the contents of the entry so that the character at the given index is the leftmost visible character. icursor ( index ) Set the insertion cursor just before the character at the given index. PlotRow = tk.Frame(root, relief='sunken')Ī = tk.Label(plotRow, text='Plot Settings ') Returns the entry's current text as a string.

However, opening a potentially endless amount of windows is terribly resource demanding. Thanks and I hope to contribute in this site more in the future! I1 = Button(FunctionRow, text='Select', padx = 5, command = CreateFunction())Ī = Label(PlotRow, text='Plot Settings ')Ĭid(column=0, row=1, sticky=(N, W, E, S))Īlso could anyone tell me how to find current coordinates of mouse? Right now its if it enters the canvas. H1 = Label(FunctionRow, text=' Function Colour: ')įunctionColourInput = Entry(FunctionRow, width=20) G1 = Label(FunctionRow, text='Function in X: ')įunctionInXInput = Entry(FunctionRow, width=35) from Tkinter import def Click(event): root Tk() x. Whenever the label changes, instead of it staying in the top, a new window opens up with the details. So, the simple example of position settings is shown bellow. Tk ().geometry ('+ Left + Top ') Here, you have to replace Left and Top with integer. So, let’s see the syntax of position setting. I am learning classes at uni so I need to learn how to use it. Set Tkinter Window Position in Python : Like above given Size setting, you can set the position using geometry option in TK () class. Self._CurrentCoordLabel = Label(CoordRow) In the top a label will show the current position of the mouse in the canvas and the position of the last click in the canvas. I am learning classes at uni so I need to learn how to use it. In the top a label will show the current position of the mouse in the canvas and the position of the last click in the canvas. I am trying to create a GUI for plotting function using Tkinter and Python. Hello, sorry for the rudeness for asking for help on the first post but I'm still a beginner in programming.
