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.

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.

The `Add`, `Insert`, and `Prepend` functions return a +pointer to the newly added `wx.SizerItem`. Just add empty space of the +desired size and attributes, and then use the `wx.SizerItem.GetRect` +method to determine where the drawing operations should take place. + +: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... + +"); + class wxSizer : public wxObject { public: // wxSizer(); **** abstract, can't instantiate @@ -168,77 +387,216 @@ public: %extend { void _setOORInfo(PyObject* _self) { - self->SetClientObject(new wxPyOORClientData(_self)); + if (!self->GetClientObject()) + self->SetClientObject(new wxPyOORClientData(_self)); } + DocAStr(Add, + "Add(self, item, int proportion=0, int flag=0, int border=0, + PyObject userData=None) -> wx.SizerItem", + + "Appends a child item to the sizer.", " + + :param item: The item can be one of three kinds of objects: + + - **window**: A `wx.Window` to be managed by 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.

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.
