339 "wx.Sizer is the abstract base class used for laying out subwindows in
340 a window. You cannot use wx.Sizer directly; instead, you will have to
341 use one of the sizer classes derived from it such as `wx.BoxSizer`,
342 `wx.StaticBoxSizer`, `wx.NotebookSizer`, `wx.GridSizer`, `wx.FlexGridSizer`
343 and `wx.GridBagSizer`.
344
345 The concept implemented by sizers in wxWidgets is closely related to
346 layout tools in other GUI toolkits, such as Java's AWT, the GTK
347 toolkit or the Qt toolkit. It is based upon the idea of the individual
348 subwindows reporting their minimal required size and their ability to
349 get stretched if the size of the parent window has changed. This will
350 most often mean that the programmer does not set the original size of
351 a dialog in the beginning, rather the dialog will assigned a sizer and
352 this sizer will be queried about the recommended size. The sizer in
353 turn will query its children, which can be normal windows or contorls,
354 empty space or other sizers, so that a hierarchy of sizers can be
355 constructed. Note that wxSizer does not derive from wxWindow and thus
356 do not interfere with tab ordering and requires very little resources
357 compared to a real window on screen.
358
359 What makes sizers so well fitted for use in wxWidgets is the fact that
360 every control reports its own minimal size and the algorithm can
361 handle differences in font sizes or different window (dialog item)
362 sizes on different platforms without problems. If for example the
363 standard font as well as the overall design of Mac widgets requires
364 more space than on Windows, then the initial size of a dialog using a
365 sizer will automatically be bigger on Mac than on Windows.", "
366
367 :note: If you wish to create a custom sizer class in wxPython you
368 should derive the class from `wx.PySizer` in order to get
369 Python-aware capabilities for the various virtual methods.

392 "Appends a child item to the sizer.", "
393
394 :param item: The item can be one of three kinds of objects:
395
396 - **window**: A `wx.Window` to be managed by the sizer. Its
397 minimal size (either set explicitly by the user or
398 calculated internally when constructed with wx.DefaultSize)
399 is interpreted as the minimal size to use when laying out
400 item in the sizer. This is particularly useful in
401 connection with `wx.Window.SetSizeHints`.
402
403 - **sizer**: The (child-)sizer to be added to the sizer. This
404 allows placing a child sizer in a sizer and thus to create
405 hierarchies of sizers (typically a vertical box as the top
406 sizer and several horizontal boxes on the level beneath).
407
408 - **size**: A `wx.Size` or a 2-element sequence of integers
409 that represents the width and height of a spacer to be added
410 to the sizer. Adding spacers to sizers gives more
411 flexibility in the design of dialogs; imagine for example a
412 horizontal box with two buttons at the bottom of a dialog:
413 you might want to insert a space between the two buttons and
414 make that space stretchable using the *proportion* value and
415 the result will be that the left button will be aligned with
416 the left side of the dialog and the right button with the
417 right side - the space in between will shrink and grow with
418 the dialog.
419
420 :param proportion: Although the meaning of this parameter is
421 undefined in wx.Sizer, it is used in `wx.BoxSizer` to indicate
422 if a child of a sizer can change its size in the main
423 orientation of the wx.BoxSizer - where 0 stands for not
424 changeable and a value of more than zero is interpreted
425 relative (a proportion of the total) to the value of other
426 children of the same wx.BoxSizer. For example, you might have
427 a horizontal wx.BoxSizer with three children, two of which are
428 supposed to change their size with the sizer. Then the two
429 stretchable windows should each be given *proportion* value of
430 1 to make them grow and shrink equally with the sizer's
431 horizontal dimension. But if one of them had a *proportion*
432 value of 2 then it would get a double share of the space
433 available after the fixed size items are positioned.
434
435 :param flag: This parameter can be used to set a number of flags
436 which can be combined using the binary OR operator ``|``. Two
437 main behaviours are defined using these flags. One is the
438 border around a window: the *border* parameter determines the
439 border width whereas the flags given here determine which
440 side(s) of the item that the border will be added. The other
441 flags determine how the sizer item behaves when the space
442 allotted to the sizer changes, and is somewhat dependent on
443 the specific kind of sizer used.
444
445 +----------------------------+------------------------------------------+
446 |- wx.TOP |These flags are used to specify |
447 |- wx.BOTTOM |which side(s) of the sizer item that |
448 |- wx.LEFT |the *border* width will apply to. |
449 |- wx.RIGHT | |
450 |- wx.ALL | |
451 | | |
452 +----------------------------+------------------------------------------+
453 |- wx.EXAPAND |The item will be expanded to fill |
454 | |the space allotted to the item. |
455 +----------------------------+------------------------------------------+
456 |- wx.SHAPED |The item will be expanded as much as |
457 | |possible while also maintaining its |
458 | |aspect ratio |
459 +----------------------------+------------------------------------------+
460 |- wx.FIXED_MINSIZE |Normally wx.Sizers will use |
461 | |`wx.Window.GetMinSize` or |
462 | |`wx.Window.GetBestSize` to determine what |
463 | |the minimal size of window items should |
464 | |be, and will use that size to calculate |
465 | |the layout. This allows layouts to adjust |
466 | |when an item changes and it's best size |
467 | |becomes different. If you would rather |
468 | |have a window item stay the size it |
469 | |started with then use wx.FIXED_MINSIZE. |
470 +----------------------------+------------------------------------------+
471 |- wx.ALIGN_CENTER |The wx.ALIGN flags allow you to specify |
472 |- wx.ALIGN_LEFT |the alignment of the item within the space|
473 |- wx.ALIGN_RIGHT |allotted to it by the sizer, ajusted for |
474 |- wx.ALIGN_TOP |the border if any. |
475 |- wx.ALIGN_BOTTOM | |
476 |- wx.ALIGN_CENTER_VERTICAL | |

992 This is determined by the proportion parameter give to items when they

994 can be zero, indicating that the window may not be resized at all, or
