问题描述
我在网上搜索了解决方案，我发现我们可以使用 Tkinter.Font 使用代码更改字体大小
helv36 = tkFont.Font(family='Helvetica',size=32,weight=tkFont.BOLD)
以下是我试图增加按钮内文本字体大小的代码，但随着文本大小的增加，它也增加了按钮大小，这是我不想要的。
from tkinter import *
from tkinter import font as tkFont
Keyboard_App = Tk()
canvas = Canvas(Keyboard_App,width=400,height=400)
canvas.place(x=0,y=0,relwidth=1,relheight=1)
background = PhotoImage(file="Images/background.png")
canvas.create_image(400,400,image=background,tags="B")
buttons = [
'1','2','3','4','5','6','7','8','9','0','=','q','w','e','r','t','y','u','i','o','p','<-','a','s','d','f','g','h','j','k','l',';','"','z','x','c','v','b','n','m',','.','/','SHIFT',' Space ',]
curBut = [-1,-1]
buttonL = [[]]
canvas_textbox = canvas.create_text(0,250,text='',anchor=NW,fill="cyan")
varRow = 1
varColumn = 0
def leftKey(event):
if curBut == [-1,-1]:
curBut[:] = [0,0]
buttonL[0][0].configure(highlightbackground='red')
elif curBut[0] == 4:
buttonL[curBut[0]][curBut[1]].configure(highlightbackground='#d9d9d9')
curBut[:] = [0,10]
buttonL[0][10].configure(highlightbackground='red')
else:
buttonL[curBut[0]][curBut[1]].configure(highlightbackground='#d9d9d9')
curBut[:] = [curBut[0],(curBut[1]-1)%11]
buttonL[curBut[0]][curBut[1]%11].configure(highlightbackground='red')
def rightKey(event):
if curBut == [-1,0]
buttonL[0][0].configure(highlightbackground='red')
else:
buttonL[curBut[0]][curBut[1]].configure(highlightbackground='#d9d9d9')
curBut[:] = [curBut[0],(curBut[1]+1)%11]
buttonL[curBut[0]][curBut[1]%11].configure(highlightbackground='red')
def upKey(event):
if curBut == [-1,0]
buttonL[0][0].configure(highlightbackground='red')
elif curBut[0] == 0:
buttonL[curBut[0]][curBut[1]].configure(highlightbackground='#d9d9d9')
curBut[:] = [(curBut[0]-1)%5,0]
buttonL[curBut[0]][curBut[1]%11].configure(highlightbackground='red')
else:
buttonL[curBut[0]][curBut[1]].configure(highlightbackground='#d9d9d9')
curBut[:] = [(curBut[0]-1)%5,curBut[1]]
buttonL[curBut[0]][curBut[1]%11].configure(highlightbackground='red')
def downKey(event):
if curBut == [-1,0]
buttonL[0][0].configure(highlightbackground='red')
elif curBut[0] == 3:
buttonL[curBut[0]][curBut[1]].configure(highlightbackground='#d9d9d9')
curBut[:] = [(curBut[0]+1)%5,0]
buttonL[curBut[0]][curBut[1]%11].configure(highlightbackground='red')
else:
buttonL[curBut[0]][curBut[1]].configure(highlightbackground='#d9d9d9')
curBut[:] = [(curBut[0]+1)%5,curBut[1]]
buttonL[curBut[0]][curBut[1]%11].configure(highlightbackground='red')
def select(value,x,y):
if curBut != [-1,-1]:
buttonL[curBut[0]][curBut[1]].configure(highlightbackground='#d9d9d9')
curBut[:] = [x,y]
buttonL[x][y].configure(highlightbackground='red')
if value == "<-":
input = entry.get("1.0",'end-2c')
entry.delete("1.0",END)
entry.insert("1.0",input,END)
elif value == " Space ":
entry.insert(END,' ')
elif value == "Tab":
entry.insert(END,' ')
else:
entry.insert(END,value)
helv36 = tkFont.Font(family='Helvetica',size=12,weight=tkFont.BOLD)
for button in buttons:
if button != " Space ":
but = Button(Keyboard_App,text=button,font=helv36,width=10,height=3,bg="#000000",fg="#ffffff",highlightthickness=4,activebackground="#ffffff",activeforeground="#000000",relief="raised",padx=12,pady=4,bd=4,command=lambda x=button,i=varRow-1,j=varColumn: select(x,i,j))
buttonL[varRow-1].append(but)
but.grid(row=varRow,column=varColumn)
if button == " Space ":
but = Button(Keyboard_App,width=60,padx=4,j))
buttonL[varRow-1].append(but)
but.grid(row=6,columnspan=16)
varColumn += 1
if varColumn > 10:
varColumn = 0
varRow += 1
buttonL.append([])
Keyboard_App.bind('<Left>',leftKey)
Keyboard_App.bind('<Right>',rightKey)
Keyboard_App.bind('<Up>',upKey)
Keyboard_App.bind('<Down>',downKey)
Keyboard_App.mainloop()
可以直接复制粘贴上面的代码，执行输出。我越是增加字体的大小，按钮的大小就会自动增加，这会导致 UI 的外观和感觉很糟糕。
我哪里出错了？
