Tkinter Text size参数

Tkinter Text size参数

size用于设置Text文字区域的字号,下面将以实例说明此参数对于文字区域字号的影响。

示例1

对Combobox对象设置字号,字号的区间是8~30,其中默认大小是12。将此对象放在weight对象右边,用户可以在Text文字区域输入文字,然后可以选择字形、weight或字号,可以看到所输入的文字将因所选择的字形或weight或字号而有不同的变化。

from tkinter import * 
from tkinter.font import Font
from tkinter.ttk import * 

def familyChanged(event):             # font family更新
    f=Font(family=familyVar.get())    # 取得新的font family
    text.configure(font=f)            # 更新text的font family
def weightChanged(event):             # weight family更新
    f=Font(weight=weightVar.get())    # 取得新的fontweight
    text.configure(font=f)            # 更新text的font weight
def sizeSelected(event):              # size family更新
    f=Font(size=sizeVar.get())        # 取得新font size
    text.configure(font=f)            # 取得text的font size

root = Tk()
root.title("apidemos.com")
root.geometry("300x180")

# 建立工具栏
toolbar = Frame(root,relief=RAISED,borderwidth=1)
toolbar.pack(side=TOP,fill=X,padx=2,pady=1)

# 建立font family OptionMenu
familyVar = StringVar()
familyFamily = ("Arial","Times","Courier")
familyVar.set(familyFamily[0])
family = OptionMenu(toolbar,familyVar,*familyFamily,command=familyChanged)
family.pack(side=LEFT,pady=2)

# 建立font weight OptionMenu
weightVar = StringVar()
weightFamily = ("normal","bold")
weightVar.set(weightFamily[0])
weight = OptionMenu(toolbar,weightVar,*weightFamily,command=weightChanged)
weight.pack(pady=3,side=LEFT)

# 建立font size Combobox
sizeVar = IntVar()
size = Combobox(toolbar,textvariable=sizeVar)
sizeFamily = [x for x in range(8,31)]
size["value"] = sizeFamily
size.current(4)
size.bind("<<ComboboxSelected>>",sizeSelected)
size.pack(side=LEFT)

# 建立Text
text = Text(root)
text.pack(fill=BOTH,expand=True,padx=3,pady=2)
text.focus_set()

root.mainloop()
