I have installed flet on my windows PC and I'm using Pycharm as my editor. When I run the python script in both the editor or using CMD, the width and height defined in the code below won't work. I have set my environment variables and I'm using the latest version of flet as of this writing. Here's a screenshot of what it looks like when I run it. Also, even though I have defined the window to not be resizable, I can still adjust the size of the window. I don't understand why those lines of code are being ignored at runtime. Any help would be much appreciated. import flet as ft def main(page: ft.Page): # Set window properties page.title = "My Flet App" page.window_width = 400 # Width in pixels page.window_height = 700 # Height in pixels page.window_resizable = False # Fix the window size #page.bgcolor = ft.Colors.WHITE # Use the updated Colors enum page.update() # Apply settings immediately # --- Define pages (content for each page) --- def home_page(): return ft.Container( content=ft.Text("Home Page Content", size=20), alignment=ft.alignment.center, expand=True, ) def daily_agenda_planner(): return ft.Container( content=ft.Text("Daily Agenda Planner Content", size=20), alignment=ft.alignment.center, expand=True, ) # Dictionary holding our pages frames = { "HomePage": home_page(), "DailyAgendaPlanner": daily_agenda_planner(), } # --- Current Page Container --- current_page = ft.Container(content=frames["HomePage"], expand=True) # Function to switch between pages def show_frame(page_name: str): current_page.content = frames[page_name] page.update() # --- Navigation Bar --- def create_nav_button(icon, tooltip, action): return ft.IconButton( icon=icon, icon_size=30, tooltip=tooltip, on_click=action, ) # Navigation button actions def on_home_click(e): show_frame("HomePage") def on_planner_click(e): show_frame("DailyAgendaPlanner") def on_contacts_click(e): print("Contacts button clicked!") def on_map_click(e): print("Nav button clicked!") def on_refresh_click(e): print("Refresh button clicked!") # Create nav bar nav_bar = ft.Row( controls=[ create_nav_button(ft.Icons.HOME, "Home", on_home_click), create_nav_button(ft.Icons.CALENDAR_TODAY, "Planner", on_planner_click), create_nav_button(ft.Icons.CONTACTS, "Contacts", on_contacts_click), create_nav_button(ft.Icons.MAP_ROUNDED, "Map", on_map_click), create_nav_button(ft.Icons.REFRESH, "Refresh", on_refresh_click), ], alignment=ft.MainAxisAlignment.CENTER, spacing=20, ) # Wrap nav bar in a container for padding nav_bar_container = ft.Container( content=nav_bar, padding=10, ) # --- Main Layout --- main_layout = ft.Column( controls=[ current_page, # Expands to fill available space. nav_bar_container, # Navigation bar at the bottom. ], expand=True, alignment=ft.MainAxisAlignment.SPACE_BETWEEN, ) page.add(main_layout) ft.app(target=main) Continue reading...
