root.attributes('-zoomed', True)建立全屏模式 - 顯示帶有工具欄的全屏模式
在本教程中，我們將介紹如何在 Tkinter 中建立全屏視窗，以及如何切換或退出全屏模式。
Windows root.attributes('-fullscreen', True) 在 Tkinter 中建立全屏模式
tk.Tk.attributes 設定特定作業系統平臺的屬性。Windows 中的屬性是
-alpha-transparentcolor-disabled-fullscreen-toolwindow-topmost
-fullscreen 指定視窗是否為全屏模式。
import tkinter as tk
class Fullscreen_Example:
def __init__(self):
self.window = tk.Tk()
self.window.attributes('-fullscreen', True)
self.fullScreenState = False
self.window.bind("<F11>", self.toggleFullScreen)
self.window.bind("<Escape>", self.quitFullScreen)
self.window.mainloop()
def toggleFullScreen(self, event):
self.fullScreenState = not self.fullScreenState
self.window.attributes("-fullscreen", self.fullScreenState)
def quitFullScreen(self, event):
self.fullScreenState = False
self.window.attributes("-fullscreen", self.fullScreenState)
if __name__ == '__main__':
app = Fullscreen_Example()
self.window.bind("<F11>", self.toggleFullScreen)
繫結 F11 到 toggleFullScreen 函式。
def toggleFullScreen(self, event):
self.fullScreenState = not self.fullScreenState
self.window.attributes("-fullscreen", self.fullScreenState)
在此函式中，fullscreen 模式被更新為跟前一狀態相反的狀態。
def quitFullScreen(self, event):
self.fullScreenState = False
self.window.attributes("-fullscreen", self.fullScreenState)
quitFullScreen 函式通過設定 -fullscreen 為 False 而退出全屏模式。
我們可以使用 lambda 函式來簡化解決方案。
import tkinter as tk
class Fullscreen_Example:
def __init__(self):
self.window = tk.Tk()
self.window.attributes('-fullscreen', True)
self.window.bind("<F11>",
lambda event: self.window.attributes("-fullscreen",
not self.window.attributes("-fullscreen")))
self.window.bind("<Escape>",
lambda event: self.window.attributes("-fullscreen",
False))
self.window.mainloop()
if __name__ == '__main__':
app = Fullscreen_Example()
self.window.bind("<F11>",
lambda event: self.window.attributes("-fullscreen",
not self.window.attributes("-fullscreen")))
它將 lambda 函式繫結到 F11，可以在其中讀取當前的全屏狀態 self.window.attributes("-fullscreen")，如果該方法中未指定任何值，則該方法返回 -fullscreen 的當前狀態。
如果遵循這種方法，我們就不再需要 fullScreenState 狀態變數。
在 Tkinter 中 Ubuntu root.attributes('-zoomed', True) 建立全屏模式
-fullscreen 屬性僅在 Windows 上存在，而在 Linux 或 macOS 上並不存在。Ubuntu 具有類似的屬性 -zoomed，可將視窗設定為全屏模式。
import tkinter as tk
class Ubuntu_Fullscreen_Example:
def __init__(self):
self.window = tk.Tk()
self.window.attributes('-zoomed', True)
self.fullScreenState = False
self.window.bind("<F11>", self.toggleFullScreen)
self.window.bind("<Escape>", self.quitFullScreen)
self.window.mainloop()
def toggleFullScreen(self, event):
self.fullScreenState = not self.fullScreenState
self.window.attributes("-zoomed", self.fullScreenState)
def quitFullScreen(self, event):
self.fullScreenState = False
self.window.attributes("-zoomed", self.fullScreenState)
if __name__ == '__main__':
app = Ubuntu_Fullscreen_Example()
顯示帶有工具欄的全屏模式
上面程式碼中顯示的全屏模式中，工具欄是不可見的。如果需要在視窗中顯示工具欄，則視窗的幾何形狀應與顯示器的尺寸相同。
import tkinter as tk
class Fullscreen_Example:
def __init__(self):
self.window = tk.Tk()
self.fullScreenState = False
self.window.attributes("-fullscreen", self.fullScreenState)
self.w, self.h = self.window.winfo_screenwidth(), self.window.winfo_screenheight()
self.window.geometry("%dx%d" % (self.w, self.h))
self.window.bind("<F11>", self.toggleFullScreen)
self.window.bind("<Escape>", self.quitFullScreen)
self.window.mainloop()
def toggleFullScreen(self, event):
self.fullScreenState = not self.fullScreenState
self.window.attributes("-fullscreen", self.fullScreenState)
def quitFullScreen(self, event):
self.fullScreenState = False
self.window.attributes("-fullscreen", self.fullScreenState)
if __name__ == '__main__':
app = Fullscreen_Example()
self.w, self.h = self.window.winfo_screenwidth(), self.window.winfo_screenheight()
winfo_screenwidth() 和 winfo_screenheight() 獲得顯示器的寬度和高度。
self.window.geometry("%dx%d" % (self.w, self.h))
使用 geometry 方法將 GUI 視窗大小設定為與顯示器的寬度和高度相同。
