We can also force updation by using winfo_idletasks(). To get the correct dimensions we have to use any event and then take the fresh data. In particular, all geometries are initially '1x1+0+0' until the widgets and geometry manager have negotiated their sizes and positions. The geometry is not accurate until the application has updated its idle tasks. My_w.winfo_idletasks(): to force the display to be updated before the application next idles My_w.winfo_screenwidth(): Screen width in pixel My_w.winfo_screenheight(): Screen height in pixel If the -displayofwinfo atom wm stackorder command to query the stacking order of Top-level windows. My_w.winfo_reqwidth(): The requested minimum width required. Tk Built-In Commands - winfo manual page winfo reqheight winfo screenmmheight winfo visualsavailable winfo vrootheight -displayof. ![]() Returns a decimal string giving the width of windows screen. My_w.winfo_reqheight(): The requested minimum height required. The winfo() method is used to retrieve information about windows managed by Tkinter. My_w.winfo_width(): The current width of the window.( May not be updated) My_w.winfo_height(): The current height of the window.( May not be updated) My_w.winfo_geometry(): The string showing size and on-screen location. Tkinter managing window geometry by width and height for dynamic creation of Buttons My_w.mainloop() # Keep the window open Dynamic window layoutīy using multiple dynamic widgets we can manage the width and height of the window. My_w.geometry(d) # update the new width and heightī1=tk.Button(my_w,text='zoom ++ ',command=lambda:my_resize('increase'))ī2=tk.Button(my_w,text='zoom - ',command=lambda:my_resize('decrease'))ī3=tk.Button(my_w,text='Full Screen',command=lambda:my_w.state('zoomed')) #my_w.maxsize(320,220) # (maximum ) width, ( maximum) height #my_w.minsize(280, 180) # (minimum ) Width, ( minimum ) height My_w.geometry(v_dim) # Size of the window In the script below some lines are commented to remove the restrictions. We have to update the data to integer by using int() while using any other type of variable.ĭ=str(int(width/2))+"x"+str(int(height/2)) My_w.maxsize(320,220) # (maximum ) width, ( maximum) height My_w.minsize(280, 180) # (minimum ) Width, ( minimum ) height These are the end limits for our height width for expansion and contraction of the window. We can restrict the height and width of the window by using minsize() and maxsize(). Import tkinter library from tkinter import Create an instance of tkinter frame win Tk() Set the Geometry win. windowWidth root.winforeqwidth() windowHeight root. ![]() We used the click event of button to call a function my_resize() and inside it change the width and height of parent window. from tkinter import root Tk() Gets the requested values of the height and widht. We can place buttons in our window to zoom in or zoom out the parent window. We can increase or decrease the width, height from inside the window by managing the geometry() option. Values for this option are normal ( default value ), iconic, withdrawn, or zoomed my_w.state('zoomed') Zooming the parent window We can only allow horizontally resizing the window.īy managing the state method we can maximize the window to full screen. My_w.resizable(width=0,height=0) # size change Not allowed By default width and height values are 1 ( True ). We can prevent this by using resizable() option. By holding and dragging the edges we can resize the window. There is a button at the top bar for the user to resize the parent window. Our parent window is referred as my_w in all our examples below. To solve this, you can use a thread-safe queue to communicate between the two threads. Accessing tkinter from a different thread can cause problems such as deadlock, as tkinter is not thread-safe. Tkinter window geometry to manage height width and zoom out using state and resizable() option main issue of not being able to access the tkinter instance from Flask, this is because Flask and tkinter are running in separate threads.
