You cannot use wx.Sizer directly; instead, you will have to use one of the sizer classes derived from it such as `wx.BoxSizer`, `wx.StaticBoxSizer`, `wx.NotebookSizer`, `wx.GridSizer`, `wx.FlexGridSizer` and `wx.GridBagSizer`. The concept implemented by sizers in wxWidgets is closely related to layout tools in other GUI toolkits, such as Java's AWT, the GTK toolkit or the Qt toolkit. It is based upon the idea of the individual subwindows reporting their minimal required size and their ability to get stretched if the size of the parent window has changed. This will most often mean that the programmer does not set the original size of a dialog in the beginning, rather the dialog will assigned a sizer and this sizer will be queried about the recommended size. The sizer in turn will query its children, which can be normal windows or contorls, empty space or other sizers, so that a hierarchy of sizers can be constructed. Note that wxSizer does not derive from wxWindow and thus do not interfere with tab ordering and requires very little resources compared to a real window on screen. What makes sizers so well fitted for use in wxWidgets is the fact that every control reports its own minimal size and the algorithm can handle differences in font sizes or different window (dialog item) sizes on different platforms without problems. If for example the standard font as well as the overall design of Mac widgets requires more space than on Windows, then the initial size of a dialog using a sizer will automatically be bigger on Mac than on Windows.", " :note: If you wish to create a custom sizer class in wxPython you should derive the class from `wx.PySizer` in order to get Python-aware capabilities for the various virtual methods. :see: `wx.SizerItem` :todo: More dscriptive text here along with some pictures...

Its minimal size (either set explicitly by the user or calculated internally when constructed with wx.DefaultSize) is interpreted as the minimal size to use when laying out item in the sizer. This is particularly useful in connection with `wx.Window.SetSizeHints`. - **sizer**: The (child-)sizer to be added to the sizer. This allows placing a child sizer in a sizer and thus to create hierarchies of sizers (typically a vertical box as the top sizer and several horizontal boxes on the level beneath). - **size**: A `wx.Size` or a 2-element sequence of integers that represents the width and height of a spacer to be added to the sizer. Adding spacers to sizers gives more flexibility in the design of dialogs; imagine for example a horizontal box with two buttons at the bottom of a dialog: you might want to insert a space between the two buttons and make that space stretchable using the *proportion* value and the result will be that the left button will be aligned with the left side of the dialog and the right button with the right side - the space in between will shrink and grow with the dialog. :param proportion: Although the meaning of this parameter is undefined in wx.Sizer, it is used in `wx.BoxSizer` to indicate if a child of a sizer can change its size in the main orientation of the wx.BoxSizer - where 0 stands for not changeable and a value of more than zero is interpreted relative (a proportion of the total) to the value of other children of the same wx.BoxSizer. For example, you might have a horizontal wx.BoxSizer with three children, two of which are supposed to change their size with the sizer. Then the two stretchable windows should each be given *proportion* value of 1 to make them grow and shrink equally with the sizer's horizontal dimension. But if one of them had a *proportion* value of 2 then it would get a double share of the space available after the fixed size items are positioned. :param flag: This parameter can be used to set a number of flags which can be combined using the binary OR operator ``|``. Two main behaviours are defined using these flags. One is the border around a window: the *border* parameter determines the border width whereas the flags given here determine which side(s) of the item that the border will be added. The other flags determine how the sizer item behaves when the space allotted to the sizer changes, and is somewhat dependent on the specific kind of sizer used. +----------------------------+------------------------------------------+ |- wx.TOP |These flags are used to specify | |- wx.BOTTOM |which side(s) of the sizer item that | |- wx.LEFT |the *border* width will apply to. | |- wx.RIGHT | | |- wx.ALL | | | | | +----------------------------+------------------------------------------+ |- wx.EXAPAND |The item will be expanded to fill | | |the space allotted to the item. | +----------------------------+------------------------------------------+ |- wx.SHAPED |The item will be expanded as much as | | |possible while also maintaining its | | |aspect ratio | +----------------------------+------------------------------------------+ |- wx.FIXED_MINSIZE |Normally wx.Sizers will use | | |`wx.Window.GetMinSize` or | | |`wx.Window.GetBestSize` to determine what | | |the minimal size of window items should | | |be, and will use that size to calculate | | |the layout.
