今年年初，我写了一篇名为《图书管理库以及操作界面》的文章（链接：http://blog.csdn.net/qq_32897527/article/details/50493313），但是由于技术问题，导致程序不是很优化，界面也不是很友好。最近得空稍微研究了下，对界面进行了升级。
1、使用表格进行数据项显示
升级前 
升级后
#coding:gbk
import wx,sqlite3
import wx.lib.sheet as sheet
class find(wx.Frame):
def load(self,event):
conn=sqlite3.connect("F:\\Python\My Program\library_system\library.db")
conn.cursor()
rel = conn.execute('SELECT * FROM library')
re = rel.fetchall()
if self.s.GetValue().encode('gbk') == '按书名':
t=[]
for i in re:
if i[1] == self.t.GetValue():
t.append(i)
rows = len(t)
self.cs.SetNumberRows(rows)
for row in range(rows):
self.cs.SetRowLabelValue(row,'%d'%t[row][0])
for col in range(4):
self.cs.SetCellValue(row,col,t[row][col+1])
dial = wx.MessageDialog(None,'共有%d个结果'%rows,'结果',wx.YES_NO)
dial.ShowModal()
if self.s.GetValue().encode('gbk') == '按出版社':
t=[]
for i in re:
if i[2] == self.t.GetValue():
t.append(i)
rows = len(t)
self.cs.SetNumberRows(rows)
for row in range(rows):
self.cs.SetRowLabelValue(row,'%d'%t[row][0])
for col in range(4):
self.cs.SetCellValue(row,col,t[row][col+1])
dial = wx.MessageDialog(None,'共有%d个结果'%rows,'结果',wx.YES_NO)
dial.ShowModal()
if self.s.GetValue().encode('gbk') == '按价格':
t=[]
for i in re:
if i[3] == self.t.GetValue():
t.append(i)
rows = len(t)
self.cs.SetNumberRows(rows)
for row in range(rows):
self.cs.SetRowLabelValue(row,'%d'%t[row][0])
for col in range(4):
self.cs.SetCellValue(row,col,t[row][col+1])
dial = wx.MessageDialog(None,'共有%d个结果'%rows,'结果',wx.YES_NO)
dial.ShowModal()
if self.s.GetValue().encode('gbk') == '按分类':
t=[]
for i in re:
if i[4] == self.t.GetValue():
t.append(i)
rows = len(t)
self.cs.SetNumberRows(rows)
for row in range(rows):
self.cs.SetRowLabelValue(row,'%d'%t[row][0])
for col in range(4):
self.cs.SetCellValue(row,col,t[row][col+1])
dial = wx.MessageDialog(None,'共有%d个结果'%rows,'结果',wx.YES_NO)
dial.ShowModal()
if self.s.GetValue().encode('gbk') == '查询全部':
t = re
rows = len(t)
self.cs.SetNumberRows(rows)
for row in range(rows):
self.cs.SetRowLabelValue(row,'%d'%t[row][0])
for col in range(4):
self.cs.SetCellValue(row,col,t[row][col+1])
dial = wx.MessageDialog(None,'共有%d个结果'%rows,'结果',wx.YES_NO)
dial.ShowModal()
if self.s.GetValue().encode('gbk') == '选择查询项':
dial = wx.MessageDialog(None,'请选择查询项','结果',wx.YES_NO)
dial.ShowModal()
def __init__(self):
wx.Frame.__init__(self, None, -1, title='查询数据',
pos=(390,200),size=(410, 400),style=wx.CAPTION | wx.CLOSE_BOX)
panel = wx.Panel(self)
panel.SetBackgroundColour('white')
self.s = wx.ComboBox(panel,value='选择查询项',
choices=['按书名','按出版社','按价格','按分类','查询全部'],pos=(20,10),size=(100,20))
self.t = wx.TextCtrl(panel,pos=(130,10),size=(185,20))
self.cs = sheet.CSheet(panel)
self.cs.SetLabelBackgroundColour('white')
self.cs.SetNumberCols(4)
self.cs.SetNumberRows(0)
self.cs.SetSize((360,320))
self.cs.SetPosition((20,40))
column = ['书名','出版社','价格','类别']
for col in range(4):
self.cs.SetColLabelValue(col,column[col])
btn=wx.Button(panel,label="查询",pos=(325,10),size=(50,20))
btn.Bind(wx.EVT_BUTTON,self.load)
if __name__ == '__main__':
app = wx.App()
find().Show()
app.MainLoop()
主要使用wx.lib.sheet库创建表格
2、用notebook将find、insert、delete三个程序合并到一起
原先的是find、insert、delete三个程序进行三个不同的操作，但是这样太过麻烦。所以使用notebook可以实现一个程序实现三个操作。
#coding:gbk
