top.columnconfigure(0,weight=1)
b1=Button(self,text="7",command=self.calculate,bg="lime")
b1.grid(column=1,row=4,columnspan=1,rowspan=1,padx=0,pady=0,ipadx=0,ipady=0,sticky='we')
''' configuring adjustability of column'''
self.columnconfigure(1,minsize=10,pad=0,weight=1)
''' configuring adjustability of rows'''
self.rowconfigure(4,weight=1)
app = Application(master=root)
app.mainloop()on(master=root)
app.mainloop()
这是输出
调整大小之前[与编译后出现的大小相同]
调整大小后
如您所见,我能够调整宽度但不能调整高度。为什么这样?
解决方法
您必须使用sticky='news'
使其粘到所有侧面-顶部( n orth),右侧( e ast),左侧( w est),波顿( s outh)
几乎没有注释的相同代码
