在Python脚本中使用Delphi控件
Python设计GUI界面的时候，有强大的WxPython，PyQt等，在Windows下也有一个PyWin32的，不过那个是纯SDK模式开发的，用起来不太方便，这两天通过P4D研究了一下Delphi和Python交互的模式，于是通过P4D写了一个模块，通过本模块，就能实现在Python脚本中使用Delphi的控件。目前转化了几个基本的控件支持，增加了几个常规函数，用来作为一般的需求。比如使用本模块创建一个简单脚本的记事本功能：
#-*-coding: gbk-*-
from DxVcl import *
class MainForm(Form):
def __init__(self, Owner):
self.Caption = "A Delphi Form..."
self.SetBounds(10, 10, 500, 400)
self.TopPanel = Panel(self)
self.TopPanel.Parent = self
self.TopPanel.Align = 1
self.Btn = Button(self)
self.Btn.SetProps(Parent=self.TopPanel, Caption="打开")
self.Btn.SetBounds(0, 3, 100, 25)
self.OnClose = self.MainFormClose
self.Btn.OnClick = self.BtnClick
self.BtnSave = Button(self)
self.BtnSave.SetProps(Parent=self.TopPanel, Caption="保存")
self.BtnSave.SetBounds(110, 3, 100, 25)
self.BtnSave.OnClick = self.BtnSaveClick
self.Mo = Memo(self)
self.Mo.Parent = self
self.Mo.Align = 5
def BtnClick(self,Sender):
#self.Caption = "测试不得闲"
#ShowMessage(StrToHex(self.Caption))
#ShowMessage(''.join(['16进制转换回来:',HexToStr(StrToHex(self.Caption))]))
#ShowMessage(IntToStr(234234))
fileName = OpenDialog('文本文件|*.txt','打开文档')
if fileName:
self.Caption = '已经打开'+fileName.encode('gbk')
self.Mo.Lines.LoadFromFile(fileName.encode('gbk'))
def BtnSaveClick(self,Sender):
if Ask(self.Handle,'确定要保存'):
fileName = SaveDialog('文本文件|*.txt','保存文档')

self.Mo.Lines.SaveToFile(fileName.encode('gbk'))

Action.Value = caFree
class DxLogForm(Form):
def __init__(self,Owner):
self.Caption = '不得闲测试窗体'
self.Position = 5
self.BorderStyle = 3
self.Width = 234
self.Height = 150
self.lb1 = Label(self)
self.lb1.SetProps(Parent = self,Caption = '用户')
self.lb1.SetBounds(40,16,28,13)
self.EdtUser = Edit(self)
self.EdtUser.SetProps(Parent = self,Text = 'dxsoft')
self.EdtUser.SetBounds(77,13,121,21)
self.lb2 = Label(self)
self.lb2.SetProps(Parent = self,Caption = '密码')
self.lb2.SetBounds(40,48,28,13)
self.EdtPwd = Edit(self)

self.EdtPwd.SetBounds(77,45,121,21)
self.BtnLog = Button(self)
self.BtnLog.SetProps(Parent = self,Caption = '登录')
self.BtnLog.SetBounds(25,80,75,25)
self.BtnLog.OnClick = self.BtnClick
self.BtnCancel = Button(self)
self.BtnCancel.SetProps(Parent = self,Caption = '取消')
self.BtnCancel.SetBounds(141,80,75,25)
self.BtnCancel.OnClick = self.BtnCancelClick
def BtnClick(self,Sender):
if self.EdtPwd.Text.decode('gbk') == '123':
ShowMessage('登录成功,打开主窗体')
#self.visible = false
#打开另一个窗体
self.ModalResult = mrok
else:
ShowMessage('密码为123')
def BtnCancelClick(self,Sender):
self.Close()
def dolog():
LogFrm = DxLogForm(None)
m = LogFrm.ShowModal() == mrok
LogFrm.Free()
return m
def main():
FreeConsole()
if dolog():
Application.Initialize()
Application.Title = 'TestApp'
f = MainForm(Application)
f.Show()
Application.Run()
else:
ShowMessage('用户取消了登录')
if __name__=='__main__':
main() 程序运行这个脚本双击运行之后的效果就是
