| - | The idea behind xml resources is to separate the interface from the code of an application. Several GUI builders use this concept for creating interfaces. For example the famous Glade.
| |
| | | | |
| - | In our example we create a simple frame window with one button. We load resources from a file, load a panel and bind an event to a button.
| |

| |
| - | <source lang="python">
| |
| - | #!/usr/bin/python
| |
| - | # xml.py
| |
| - |
| |
| - | import wx
| |
| - | import wx.xrc as xrc
| |
| - |
| |
| - |
| |
| - | class Xml(wx.Frame):
| |
| - | def __init__(self, parent, id, title):
| |
| - | wx.Frame.__init__(self, parent, id, title)
| |
| - |
| |
| - | res = xrc.XmlResource('resource.xrc')
| |
| - | res.LoadPanel(self, 'MyPanel')
| |
| - |
| |
| - | self.Bind(wx.EVT_BUTTON, self.OnClose, id=xrc.XRCID('CloseButton'))
| |
| - | self.Center()
| |
| - | self.Show(True)
| |
| - |
| |
| - |
| |
| - | def OnClose(self, event):
| |
| - | self.Close()
| |
| - |
| |
| - | app = wx.App()
| |
| - | Xml(None, -1, 'xml.py')
| |
| - | app.MainLoop()
| |
| - | </source>

| |
| - | This is resource file resource.xrc It is a xml file, where we define our widgets and their patterns. In thid file, we use tags like
| |
| - | <source lang="python"><object></object>, <item></item></source>
| |
| - | etc.
| |
| - |
| |
| - | <source lang="python">
| |
| - | <?xml version="1.0" ?>
| |
| - | <resource>
| |
| - | <object class="wxPanel" name="MyPanel">
| |
| - | <object class="wxButton" name="CloseButton">
| |
| - | <label>Close</label>
| |
| - |
| |
| - | <pos>15,10</pos>
| |
| - | </object>
| |
| - | </object>
| |
| - | </resource>
| |
| - | </source>
| |
| - |
| |
| - | We use these two calls for working with widgets:
| |
| - |
| |
| - | * XRCID(resource_name) - gives us the id of a button or menu item
| |
| - | * XRCCTRL(resource_name) - gives us the handlers of our widgets defined in resource file
