如何使用appJar获得屏幕宽度和高度?

appJar 只是一个包裹 tkinter ,您需要参考 root / master 的实例 Tk() self.topLevel 在里面 gui . 或者,你可以参考更漂亮的 self.appWindow 自己顶级 .

为了让所有事情都清楚,只需为继承类的所需方法添加一些“快捷方式”!

import appJar as aJ

class App(aJ.gui):
    def __init__(self, *args, **kwargs):
        aJ.gui.__init__(self, *args, **kwargs)

    def winfo_screenheight(self):
        #   shortcut to height
        #   alternatively return self.topLevel.winfo_screenheight() since topLevel is Tk (root) instance!
        return self.appWindow.winfo_screenheight()

    def winfo_screenwidth(self):
        #   shortcut to width
        #   alternatively return self.topLevel.winfo_screenwidth() since topLevel is Tk (root) instance!
        return self.appWindow.winfo_screenwidth()


app = App('winfo')
height, width = app.winfo_screenheight(), app.winfo_screenwidth()
app.setGeometry(int(width / 2), int(height / 2))
app.addLabel('winfo_height', 'height: %d' % height, 0, 0)
app.addLabel('winfo_width', 'width: %d' % width, 1, 0)
app.go()

幸运地 appJar 允许您创建 Tk() 例子因此,我能够使用函数创建一个实例来检索维度并销毁当时不需要的实例。

# import appjar
from appJar import appjar

# Create an app instance to get the screen dimensions
root = appjar.Tk()

# Save the screen dimensions
width = root.winfo_screenwidth()
height = root.winfo_screenheight()

# Destroy the app instance after retrieving the screen dimensions
root.destroy()
