Layout management in wxPythonhttp://www.zetcode.com/wxpython/layout/Home ContentsPython IDEFaster, Easier Python Development Editor,Debugger, Browser, and moreGarment Size MarkersMini Markers, Sizers, Size Clips. Manufacturerwith worldwide sales.Layout management in wxPythonA typical application consists of various widgets. Those widgets are placed insidecontainer widgets. A programmer must manage the layout of the application. This isnot an easy task. In wxPython we have two options.absolute positioningsizersAbsolute PositioningThe programmer specifies the position and the size of each widget in pixels. Whenyou use absolute positioning, you have to understand several things.the size and the position of a widget do not change, if you resize a windowapplications look different (crappy) on various platformschanging fonts in your application might spoil the layoutif you decide to change your layout, you must completely redo your layout,which is tedious and time consumingThere might be situations, where we can possibly use absolute positioning. Forexample, my tutorials. I do not want to make the examples too difficult, so I oftenuse absolute positioning to explain a topic. But mostly, in real world programs,programmers use sizers.In our example we have a simple skeleton of a text editor. If we resize the window,the size of out wx.TextCtrl does not change as we would expect.Figure: before resizementFigure: after resizement1 de 17 27/04/2008 1:03
Layout management in wxPythonhttp://www.zetcode.com/wxpython/layout/#!/usr/bin/python# absolute.pyimport wxclass Absolute(wx.Frame):def __init__(self, parent, id, title):wx.Frame.__init__(self, parent, id, title, size=(250, 180))panel = wx.Panel(self, -1)menubar = wx.MenuBar()file = wx.Menu()edit = wx.Menu()help = wx.Menu()menubar.Append(file, '&File')menubar.Append(edit, '&Edit')menubar.Append(help, '&Help')self.SetMenuBar(menubar)wx.TextCtrl(panel, -1, pos=(-1, -1), size=(250, 150))self.Centre()self.Show(True)app = wx.App(0)Absolute(None, -1, '')app.MainLoop()wx.TextCtrl(panel, -1, pos=(-1, -1), size=(250, 150))We do the absolute positioning in the constructor of the wx.TextCtrl. In our case, weprovide the default position for the widget. The width is 250px and the height 150px.Using sizersSizers do address all those issues, we mentioned by absolute positioning. We canchoose among these sizers.wx.BoxSizerwx.StaticBoxSizerwx.GridSizerwx.FlexGridSizerwx.GridBagSizer2 de 17 27/04/2008 1:03
