Sizer - небольшая бесплатная утилита, которая позволяет легко изменять размер окна любого приложения. Программа способна не только автоматически менять размер окон, но и умеет запоминать их расположение на рабочем столе. Также присутствует возможность создания различных пользовательских профилей.

Sizers, as represented by the wx. 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. 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. The next section describes and shows what can be done with sizers. The following sections briefly describe how to program with individual sizer classes. 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.

Sizer:

A Strategy offers methods to trade, namely: buy , sell and close. Notice that size has a default value of None if the caller does not specify it. This is where Sizers play an important role:. This obviously implies that Strategies have a Sizer : Yes, indeed!. The background machinery adds a default sizer to a Strategy if the user has not added one. The default Sizer added to a strategy is SizerFix. The initial lines of the definition:. Adds a Sizer that will be applied to any strategy added to cerebro.

C-section (Cesarean Delivery):

You cannot use wxSizer directly; instead, you will have to use one of the sizer classes derived from it. 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 be 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, empty space or other sizers, so that a hierarchy of sizers can be constructed. 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. 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. Sizers may also be used to control the layout of custom drawn items on the window. Just add empty space of the desired size and attributes, and then use the wxSizerItem::GetRect method to determine where the drawing operations should take place.
