This is a tutorial for python when used with wx.
Too tired, I'll finish later.
I'll start with the source code.
First we start with a simple frame. To make a text box we use the wx.TextCtrl widget. By default, it is only a single-line input, but the wx.TE_MULTILINE parameter lets us enter multiple lines.
Now let's add a few menu bars. They are all pretty self explanatory and shouldn't really give much trouble.
Too tired, I'll finish later.
I'll start with the source code.
Code:
import wx
import os.path
class MainWindow(wx.Frame):
def __init__(self, filename='noname.txt'):
super(MainWindow, self).__init__(None, size=(400,200))
self.filename = filename
self.dirname = '.'
self.CreateInteriorWindowComponents()
self.CreateExteriorWindowComponents()
def CreateInteriorWindowComponents(self):
''' Create "interior" window components. In this case it is just a
simple multiline text control. '''
self.control = wx.TextCtrl(self, style=wx.TE_MULTILINE)
def CreateExteriorWindowComponents(self):
''' Create "exterior" window components, such as menu and status
bar. '''
self.CreateMenu()
self.CreateStatusBar()
self.SetTitle()
def CreateMenu(self):
fileMenu = wx.Menu()
for id, label, helpText, handler in \
[(wx.ID_ABOUT, '&About', 'Information about this program',
self.OnAbout),
(wx.ID_OPEN, '&Open', 'Open a new file', self.OnOpen),
(wx.ID_SAVE, '&Save', 'Save the current file', self.OnSave),
(wx.ID_SAVEAS, 'Save &As', 'Save the file under a different name',
self.OnSaveAs),
(None, None, None, None),
(wx.ID_EXIT, 'E&xit', 'Terminate the program', self.OnExit)]:
if id == None:
fileMenu.AppendSeparator()
else:
item = fileMenu.Append(id, label, helpText)
self.Bind(wx.EVT_MENU, handler, item)
menuBar = wx.MenuBar()
menuBar.Append(fileMenu, '&File') # Add the fileMenu to the MenuBar
self.SetMenuBar(menuBar) # Add the menuBar to the Frame
def SetTitle(self):
# MainWindow.SetTitle overrides wx.Frame.SetTitle, so we have to
# call it using super:
super(MainWindow, self).SetTitle('Editor %s'%self.filename)
# Helper methods:
def defaultFileDialogOptions(self):
''' Return a dictionary with file dialog options that can be
used in both the save file dialog as well as in the open
file dialog. '''
return dict(message='Choose a file', defaultDir=self.dirname,
wildcard='*.*')
def askUserForFilename(self, **dialogOptions):
dialog = wx.FileDialog(self, **dialogOptions)
if dialog.ShowModal() == wx.ID_OK:
userProvidedFilename = True
self.filename = dialog.GetFilename()
self.dirname = dialog.GetDirectory()
self.SetTitle() # Update the window title with the new filename
else:
userProvidedFilename = False
dialog.Destroy()
return userProvidedFilename
# Event handlers:
def OnAbout(self, event):
dialog = wx.MessageDialog(self, 'A sample editor\n'
'in wxPython', 'About Sample Editor', wx.OK)
dialog.ShowModal()
dialog.Destroy()
def OnExit(self, event):
self.Close() # Close the main window.
def OnSave(self, event):
textfile = open(os.path.join(self.dirname, self.filename), 'w')
textfile.write(self.control.GetValue())
textfile.close()
def OnOpen(self, event):
if self.askUserForFilename(style=wx.OPEN,
**self.defaultFileDialogOptions()):
textfile = open(os.path.join(self.dirname, self.filename), 'r')
self.control.SetValue(textfile.read())
textfile.close()
def OnSaveAs(self, event):
if self.askUserForFilename(defaultFile=self.filename, style=wx.SAVE,
**self.defaultFileDialogOptions()):
self.OnSave(event)
app = wx.App()
frame = MainWindow()
frame.Show()
app.MainLoop()First we start with a simple frame. To make a text box we use the wx.TextCtrl widget. By default, it is only a single-line input, but the wx.TE_MULTILINE parameter lets us enter multiple lines.
Code:
1 #!/usr/bin/env python
2 import wx
3 class MyFrame(wx.Frame):
4 """ We simply derive a new class of Frame. """
5 def __init__(self, parent, title):
6 wx.Frame.__init__(self, parent, title=title, size=(200,100))
7 self.control = wx.TextCtrl(self, style=wx.TE_MULTILINE)
8 self.Show(True)
9
10 app = wx.App(False)
11 frame = MyFrame(None, 'Small editor')
12 app.MainLoop()Now let's add a few menu bars. They are all pretty self explanatory and shouldn't really give much trouble.
Code:
1 import wx
2
3 class MainWindow(wx.Frame):
4 def __init__(self, parent, title):
5 wx.Frame.__init__(self, parent, title=title, size=(200,100))
6 self.control = wx.TextCtrl(self, style=wx.TE_MULTILINE)
7 self.CreateStatusBar() # A Statusbar in the bottom of the window
8
9 # Setting up the menu.
10 filemenu= wx.Menu()
11
12 # wx.ID_ABOUT and wx.ID_EXIT are standard IDs provided by wxWidgets.
13 filemenu.Append(wx.ID_ABOUT, "&About"," Information about this program")
14 filemenu.AppendSeparator()
15 filemenu.Append(wx.ID_EXIT,"E&xit"," Terminate the program")
16
17 # Creating the menubar.
18 menuBar = wx.MenuBar()
19 menuBar.Append(filemenu,"&File") # Adding the "filemenu" to the MenuBar
20 self.SetMenuBar(menuBar) # Adding the MenuBar to the Frame content.
21 self.Show(True)
22
23 app = wx.App(False)
24 frame = MainWindow(None, "Sample editor")
25 app.MainLoop()
