在PythonStudio中，实现父子窗口间传递参数

一、方法一：发起方主动
1.1父窗体：
添加控件Lable，Edit,Button

1.2父窗体代码

import os
from glcl import *
# 需要引入子窗体类
from Unit2 import *

class Form1(Form):

    def __init__(self, owner):
        self.Label1 = Label(self)
        self.Button1 = Button(self)
        self.Edit1 = Edit(self)
        self.LoadProps(os.path.join(os.path.dirname(os.path.abspath(__file__)), "Unit1.pydfm"))
        self.Button1.OnClick = self.Button1Click


    def Button1Click(self, Sender):
    	# 创建子窗体，并设置所有者为当前窗体
        self.Frm2=Form2(self)
        # 按层级传递给子窗体下的标签
        self.Frm2.label1.Caption=self.Edit1.Text
        self.Frm2.Show()

2.1子窗体
添加控件Lable，Edit,Button

2.2 子窗体代码

import os
from glcl import *

class Form2(Form):

    def __init__(self, owner):
        self.Button1 = Button(self)
        self.Edit1 = Edit(self)
        self.Label1 = Label(self)
        self.LoadProps(os.path.join(os.path.dirname(os.path.abspath(__file__)), "Unit2.pydfm"))
        self.Button1.OnClick = self.Button1Click


    def Button1Click(self, Sender):
    	# 直接用self.Owner来指向父窗体的实例
        self.Owner.Label1.Caption=self.Edit1.Text

二、方法二：接收方主动
子窗体代码

import os
from glcl import *

class Form2(Form):

    def __init__(self, owner):
        self.Button1 = Button(self)
        self.Edit1 = Edit(self)
        self.Label1 = Label(self)
        self.LoadProps(os.path.join(os.path.dirname(os.path.abspath(__file__)), "Unit2.pydfm"))
        self.Button1.OnClick = self.Button1Click
		# 在初始化时就直接取得父窗体的控件内容，注意是小写的owner，是父级的实例
        self.Label1.Caption=owner.Edit1.Text

三、需要字典、列表、对象等作为参数
1 在父窗体中初始化中设置变量

import os
from glcl import *
from Unit2 import *

class Form1(Form):

    def __init__(self, owner):
        self.Label1 = Label(self)
        self.Button1 = Button(self)
        self.Edit1 = Edit(self)
        self.LoadProps(os.path.join(os.path.dirname(os.path.abspath(__file__)), "Unit1.pydfm"))
        self.Button1.OnClick = self.Button1Click

        # 需要传递的内容，此处以数组为例
        self.ParaDic=[1,2,3,4]

    def Button1Click(self, Sender):
        self.Frm2=Form2(self)
        self.Frm2.Show()

2 在子窗体中直接调用

import os
from glcl import *

class Form2(Form):

    def __init__(self, owner):
        self.Button1 = Button(self)
        self.Edit1 = Edit(self)
        self.Label1 = Label(self)
        self.LoadProps(os.path.join(os.path.dirname(os.path.abspath(__file__)), "Unit2.pydfm"))
        self.Button1.OnClick = self.Button1Click

        i=0
        # 用owner来确认父窗体
        for item in owner.ParaDic:
            i+=item
        self.Label1.Caption=str(i)
