374 "wx.Sizer is the abstract base class used for laying out subwindows in
375 a window. You cannot use wx.Sizer directly; instead, you will have to
376 use one of the sizer classes derived from it such as `wx.BoxSizer`,
377 `wx.StaticBoxSizer`, `wx.GridSizer`, `wx.FlexGridSizer` and
380 The concept implemented by sizers in wxWidgets is closely related to
381 layout tools in other GUI toolkits, such as Java's AWT, the GTK
382 toolkit or the Qt toolkit. It is based upon the idea of the individual
383 subwindows reporting their minimal required size and their ability to
384 get stretched if the size of the parent window has changed. This will
385 most often mean that the programmer does not set the original size of
386 a dialog in the beginning, rather the dialog will assigned a sizer and
387 this sizer will be queried about the recommended size. The sizer in
388 turn will query its children, which can be normal windows or contorls,
389 empty space or other sizers, so that a hierarchy of sizers can be
390 constructed. Note that wxSizer does not derive from wxWindow and thus
391 do not interfere with tab ordering and requires very little resources
392 compared to a real window on screen.
394 What makes sizers so well fitted for use in wxWidgets is the fact that
395 every control reports its own minimal size and the algorithm can
396 handle differences in font sizes or different window (dialog item)
397 sizes on different platforms without problems. If for example the
398 standard font as well as the overall design of Mac widgets requires
399 more space than on Windows, then the initial size of a dialog using a
400 sizer will automatically be bigger on Mac than on Windows.", "
402 Sizers may also be used to control the layout of custom drawn items on
403 the window. The `Add`, `Insert`, and `Prepend` functions return a
404 pointer to the newly added `wx.SizerItem`. Just add empty space of the
405 desired size and attributes, and then use the `wx.SizerItem.GetRect`
406 method to determine where the drawing operations should take place.
408 :note: If you wish to create a custom sizer class in wxPython you
409 should derive the class from `wx.PySizer` in order to get
410 Python-aware capabilities for the various virtual methods.
414 :todo: More dscriptive text here along with some pictures...

431 "Add(self, item, int proportion=0, int flag=0, int border=0,
432 PyObject userData=None) -> wx.SizerItem",
434 "Appends a child item to the sizer.", "
436 :param item: The item can be one of three kinds of objects:
438 - **window**: A `wx.Window` to be managed by the sizer. Its
439 minimal size (either set explicitly by the user or
440 calculated internally when constructed with wx.DefaultSize)
441 is interpreted as the minimal size to use when laying out
442 item in the sizer. This is particularly useful in
443 connection with `wx.Window.SetSizeHints`.
445 - **sizer**: The (child-)sizer to be added to the sizer. This
446 allows placing a child sizer in a sizer and thus to create
447 hierarchies of sizers (typically a vertical box as the top
448 sizer and several horizontal boxes on the level beneath).
450 - **size**: A `wx.Size` or a 2-element sequence of integers
451 that represents the width and height of a spacer to be added
452 to the sizer. Adding spacers to sizers gives more
453 flexibility in the design of dialogs; imagine for example a
454 horizontal box with two buttons at the bottom of a dialog:
455 you might want to insert a space between the two buttons and
456 make that space stretchable using the *proportion* value and
457 the result will be that the left button will be aligned with
458 the left side of the dialog and the right button with the
459 right side - the space in between will shrink and grow with
462 :param proportion: Although the meaning of this parameter is
463 undefined in wx.Sizer, it is used in `wx.BoxSizer` to indicate
464 if a child of a sizer can change its size in the main
465 orientation of the wx.BoxSizer - where 0 stands for not
466 changeable and a value of more than zero is interpreted
467 relative (a proportion of the total) to the value of other
468 children of the same wx.BoxSizer. For example, you might have
469 a horizontal wx.BoxSizer with three children, two of which are
470 supposed to change their size with the sizer. Then the two
471 stretchable windows should each be given *proportion* value of
472 1 to make them grow and shrink equally with the sizer's
473 horizontal dimension. But if one of them had a *proportion*
474 value of 2 then it would get a double share of the space
475 available after the fixed size items are positioned.
477 :param flag: This parameter can be used to set a number of flags
478 which can be combined using the binary OR operator ``|``. Two
479 main behaviours are defined using these flags. One is the
480 border around a window: the *border* parameter determines the
481 border width whereas the flags given here determine which
482 side(s) of the item that the border will be added. The other
483 flags determine how the sizer item behaves when the space
484 allotted to the sizer changes, and is somewhat dependent on
485 the specific kind of sizer used.
487 +----------------------------+------------------------------------------+
488 |- wx.TOP |These flags are used to specify |
489 |- wx.BOTTOM |which side(s) of the sizer item that |
490 |- wx.LEFT |the *border* width will apply to. |
494 +----------------------------+------------------------------------------+
495 |- wx.EXPAND |The item will be expanded to fill |
496 | |the space allotted to the item. |
497 +----------------------------+------------------------------------------+
498 |- wx.SHAPED |The item will be expanded as much as |
499 | |possible while also maintaining its |
501 +----------------------------+------------------------------------------+
502 |- wx.FIXED_MINSIZE |Normally wx.Sizers will use |
503 | |`wx.Window.GetMinSize` or |
504 | |`wx.Window.GetBestSize` to determine what |
505 | |the minimal size of window items should |
506 | |be, and will use that size to calculate |
507 | |the layout. This allows layouts to adjust |
508 | |when an item changes and it's best size |
509 | |becomes different. If you would rather |
510 | |have a window item stay the size it |
511 | |started with then use wx.FIXED_MINSIZE. |
512 +----------------------------+------------------------------------------+
513 |- wx.ALIGN_CENTER |The wx.ALIGN flags allow you to specify |
514 |- wx.ALIGN_LEFT |the alignment of the item within the space|
515 |- wx.ALIGN_RIGHT |allotted to it by the sizer, ajusted for |
516 |- wx.ALIGN_TOP |the border if any. |
517 |- wx.ALIGN_BOTTOM | |
518 |- wx.ALIGN_CENTER_VERTICAL | |
519 |- wx.ALIGN_CENTER_HORIZONTAL| |

524 parameter is set to include any border flag.

1152 directions (height and width) but can distribute its growth in the
1153 main direction (horizontal for a row) *unevenly* among its children.
1154 This is determined by the proportion parameter give to items when they
1155 are added to the sizer. It is interpreted as a weight factor, i.e. it
1156 can be zero, indicating that the window may not be resized at all, or
1157 above zero. If several windows have a value above zero, the value is
1158 interpreted relative to the sum of all weight factors of the sizer, so
1159 when adding two windows with a value of 1, they will both get resized
1160 equally and each will receive half of the available space after the
1161 fixed size items have been sized. If the items have unequal
1162 proportion settings then they will receive a coresondingly unequal
