Note that wxSizer does not derive from wxWindow and thus does not interfere with tab ordering and requires very little resources compared to a real window on screen. The sizer in turn will query its children, which can be normal windows, empty space or other sizers, so that a hierarchy of sizers can be constructed.

This will most often mean that the programmer does not set the original size of a dialog in the beginning, rather the dialog will be assigned a sizer and this sizer will be queried about the recommended size. 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. You cannot use wxSizer directly instead, you will have to use one of the sizer classes derived from it.

Adds a Sizer that will be applied to any strategy added to cerebro. The default Sizer added to a strategy is SizerFix. The background machinery adds a default sizer to a Strategy if the user has not added one. This obviously implies that Strategies have a Sizer : Yes, indeed!. This is where Sizers play an important role. Notice that size has a default value of None if the caller does not specify it. It is based upon the idea of individual subwindows reporting their minimal required size and their ability to get stretched if the size of the parent window has changed.Ī Strategy offers methods to trade, namely: buy, sell and close.

The following sections briefly describe how to program with individual sizer classes. The next section describes and shows what can be done with sizers. Editors such as wxDesigner, DialogBlocks, XRCed and wxWorkshop create dialogs based exclusively on sizers, practically forcing the user to create platform independent layouts without compromises.

Sizer class and its descendants in the wxPython class hierarchy, have become the method of choice to define the layout of controls in dialogs in wxPython because of their ability to create visually appealing dialogs independent of the platform, taking into account the differences in size and style of the individual controls.
