Panel and event handler
this example from a Well House Consultants training course
Source code: wx04.py Module: Y207
import wx
# Set up a panel within a frame with a load of widgets # Set up events on each of the widgets # display the results in a scrolling text frame class Form1(wx.Panel): def __init__(self, parent): wx.Panel.__init__(self, parent) # Set up some basic element. Placement is a bit crude as this # is really an event handling demo! It would also be a good idea # to define constants for the IDs! self.quote = wx.StaticText(self, -1, "Your quote :",wx.Point(20, 30)) self.logger = wx.TextCtrl(self,5, "",wx.Point(330,20), wx.Size(200,300), \ wx.TE_MULTILINE | wx.TE_READONLY) self.button = wx.Button(self, 10, "Save", wx.Point(200, 325)) self.leaver = wx.Button(self, 11, "Quit", wx.Point(200, 355)) self.lblname = wx.StaticText(self, -1, "Your name :",wx.Point(20,60)) self.editname = wx.TextCtrl(self, 20, "Enter here your name", wx.Point(170, 60), wx.Size(140,-1)) self.lblhear = wx.StaticText(self,-1,"How did you hear about us ?",wx.Point(20, 90)) self.sampleList = ['friends', 'colleagues', 'advertising', 'web search'] self.edithear=wx.ComboBox(self, 30, "", wx.Point(170, 90), wx.Size(95, -1), self.sampleList, wx.CB_DROPDOWN) self.insure = wx.CheckBox(self, 40, "Do you want Insured Shipment ?",wx.Point(20,180)) self.radioList = ['blue', 'red', 'yellow', 'orange', 'green', 'magenta', 'black', 'grey'] rb = wx.RadioBox(self, 50, "What colour would you like ?", wx.Point(20, 210), wx.DefaultSize, self.radioList, 4, wx.RA_SPECIFY_COLS) # Add event handlers as appropriate # Two handlers on id #30 as it's a select box you can also type into wx.EVT_BUTTON(self, 10, self.OnClick) wx.EVT_BUTTON(self, 11, self.OnClick) # Share handler between several ids wx.EVT_TEXT(self, 20, self.EvtText) wx.EVT_CHAR(self.editname, self.EvtChar) # on id 20 wx.EVT_COMBOBOX(self, 30, self.EvtComboBox) wx.EVT_TEXT(self, 30, self.EvtText) wx.EVT_CHECKBOX(self, 40, self.EvtCheckBox) wx.EVT_RADIOBOX(self, 50, self.EvtRadioBox) # parent is the top level frame - we can title a frame but # not a panel! parent.SetTitle("Quotation Request") # Absolute placement as we've done above is NOT a good idea, but it # does mean that this demo lets you see the events more easily. What # you should do is use a sizer, and then set the parent's size with # the following (or the equivalent) # parent.SetSizerAndFit(sizer) def EvtRadioBox(self, event): self.logger.AppendText('EvtRadioBox: %d\n' % event.GetInt()) def EvtComboBox(self, event): self.logger.AppendText('EvtComboBox: %s\n' % event.GetString()) def OnClick(self,event): self.logger.AppendText(" Click on object with Id %d\n" %event.GetId()) if event.GetId() == 11: frame.Destroy() def EvtText(self, event): self.logger.AppendText('EvtText: %s\n' % event.GetString()) def EvtChar(self, event): self.logger.AppendText('EvtChar: %d\n' % event.GetKeyCode()) event.Skip() def EvtCheckBox(self, event): self.logger.AppendText('EvtCheckBox: %d\n' % event.Checked()) app = wx.PySimpleApp() frame = wx.Frame(None, size=(550,425)) # top level window # We have only had to set the size because the simple layout used # hasn't allowed for an automatic sizing.
