10 @class wxStdDialogButtonSizer
13 This class creates button layouts which conform to the standard button spacing
14 and ordering defined by the platform
15 or toolkit's user interface guidelines (if such things exist). By using this
16 class, you can ensure that all your
17 standard dialogs look correct on all major platforms. Currently it conforms to
18 the Windows, GTK+ and Mac OS X
19 human interface guidelines.
21 When there aren't interface guidelines defined for a particular platform or
22 toolkit, wxStdDialogButtonSizer reverts
23 to the Windows implementation.
25 To use this class, first add buttons to the sizer by calling AddButton (or
26 SetAffirmativeButton, SetNegativeButton,
27 or SetCancelButton) and then call Realize in order to create the actual button
28 layout used. Other than these special
29 operations, this sizer works like any other sizer.
31 If you add a button with wxID_SAVE, on Mac OS X the button will be renamed to
33 the wxID_NO button will be renamed to "Don't Save" in accordance with the Mac
34 OS X Human Interface Guidelines.

40 wxDialog::CreateButtonSizer
42 class wxStdDialogButtonSizer
: public wxBoxSizer
46 Constructor for a wxStdDialogButtonSizer.
48 wxStdDialogButtonSizer();
51 Adds a button to the wxStdDialogButtonSizer. The button must have one of the
52 following identifiers:
63 void AddButton(wxButton
* button
);
66 Rearranges the buttons and applies proper spacing between buttons to make them
67 match the platform or toolkit's interface guidelines.
72 Sets the affirmative button for the sizer. This allows you to use identifiers
73 other than the standard identifiers outlined above.
75 void SetAffirmativeButton(wxButton
* button
);
78 Sets the cancel button for the sizer. This allows you to use identifiers other
79 than the standard identifiers outlined above.
81 void SetCancelButton(wxButton
* button
);
84 Sets the negative button for the sizer. This allows you to use identifiers
85 other than the standard identifiers outlined above.
87 void SetNegativeButton(wxButton
* button
);
96 The wxSizerItem class is used to track the position, size and other
97 attributes of each item managed by a wxSizer. It is not usually necessary
98 to use this class because the sizer elements can also be identified by
99 their positions or window or sizer pointers but sometimes it may be more
100 convenient to use it directly.
105 class wxSizerItem
: public wxObject
110 Construct a sizer item for tracking a subsizer.
112 wxSizerItem(int width
, int height
, int proportion
, int flag
,
113 int border
, wxObject
* userData
);
114 wxSizerItem(wxWindow
* window
, const wxSizerFlags
& flags
);
115 wxSizerItem(wxWindow
* window

,
118 wxSizerItem(wxSizer
* window
, const wxSizerFlags
& flags
);
119 wxSizerItem(wxSizer
* sizer

142 Enable deleting the SizerItem without destroying the contained sizer.
147 Return the border attribute.
149 int GetBorder() const;
152 Return the flags attribute.
154 See @ref wxsizer_flags "wxSizer flags list" for details.
159 Return the numeric id of wxSizerItem, or @c wxID_NONE if the id has
165 Get the minimum size needed for the item.

170 What is the current position of the item, as set in the last Layout.
172 wxPoint
GetPosition() const;
175 Get the proportion item attribute.
177 int GetProportion() const;
180 Get the ration item attribute.
182 float GetRatio() const;
185 Get the rectangle of the item on the parent window, excluding borders.
190 Get the current size of the item, as set in the last Layout.
192 wxSize
GetSize() const;
195 If this item is tracking a sizer, return it. @NULL otherwise.

200 If this item is tracking a spacer, return its size.
202 const wxSize
GetSpacer() const;
205 Get the userData item attribute.
207 wxObject
* GetUserData() const;
210 If this item is tracking a window then return it. @NULL otherwise.
212 wxWindow
* GetWindow() const;
215 Returns @true if this item is a window or a spacer and it is shown or
216 if this item is a sizer and not all of its elements are hidden.
218 In other words, for sizer items, all of the child elements must be
219 hidden for the sizer itself to be considered hidden.
221 As an exception, if the @c wxRESERVE_SPACE_EVEN_IF_HIDDEN flag was
222 used for this sizer item, then IsShown() always returns @true for it
223 (see wxSizerFlags::ReserveSpaceEvenIfHidden()).
225 bool IsShown() const;
228 Is this item a sizer?
230 bool IsSizer() const;
233 Is this item a spacer?
235 bool IsSpacer() const;
238 Is this item a window?
240 bool IsWindow() const;
243 Set the border item attribute.
245 void SetBorder(int border
);
248 Set the position and size of the space allocated to the sizer, and
249 adjust the position and size of the item to be within that space
250 taking alignment and borders into account.
252 void SetDimension(const wxPoint
& pos
, const wxSize
& size
);
255 Set the flag item attribute.
257 void SetFlag(int flag
);
260 Sets the numeric id of the wxSizerItem to @e id.
267 void SetInitSize(int x
, int y

276 Set the ratio item attribute.
278 void SetRatio(int width
, int height
);
279 void SetRatio(wxSize size
);
280 void SetRatio(float ratio
);
284 Set the sizer tracked by this item.
286 void SetSizer(wxSizer
* sizer
);
289 Set the size of the spacer tracked by this item.
291 void SetSpacer(const wxSize
& size
);
294 Set the window to be tracked by thsi item.
296 void SetWindow(wxWindow
* window
);
299 Set the show item attribute, which sizers use to determine if the item
300 is to be made part of the layout or not. If the item is tracking a
301 window then it is shown or hidden as needed.
303 void Show(bool show
);
312 Normally, when you add an item to a sizer via
313 wxSizer::Add, you have to specify a lot of flags and
314 parameters which can be unwieldy. This is where wxSizerFlags comes in: it
315 allows you to specify all parameters using the named methods instead. For
319 sizer->Add(ctrl, 0, wxEXPAND | wxALL, 10);
325 sizer->Add(ctrl, wxSizerFlags().Expand().Border(10));
328 This is more readable and also allows you to create wxSizerFlags objects which
329 can be reused for several sizer items.
332 wxSizerFlags flagsExpand(1);
333 flagsExpand.Expand().Border(10);
335 sizer->Add(ctrl1, flagsExpand);
336 sizer->Add(ctrl2, flagsExpand);
339 Note that by specification, all methods of wxSizerFlags return the wxSizerFlags
340 object itself to allowing chaining multiple methods calls like in the examples
352 Creates the wxSizer with the proportion specified by @e proportion.
354 wxSizerFlags(int proportion
= 0);
357 Sets the alignment of this wxSizerFlags to @e align. Note that if this
358 method is not called, the wxSizerFlags has no specified alignment.
360 @see Top(), Left(), Right(), Bottom(), Centre()
362 wxSizerFlags
& Align(int align
= 0);
365 Sets the wxSizerFlags to have a border of a number of pixels specified
366 by @a borderinpixels with the directions specified by @e direction.
368 wxSizerFlags
& Border(int direction
, int borderinpixels
);
371 Sets the wxSizerFlags to have a border with size as returned by
374 @param direction Direction(s) to apply the border in.
376 wxSizerFlags
& Border(int direction
= wxALL
);
379 Aligns the object to the bottom, shortcut for @c Align(wxALIGN_BOTTOM).
383 wxSizerFlags
& Bottom();
386 Sets the object of the wxSizerFlags to center itself in the area it is
389 wxSizerFlags
& Center();
392 Center() for people with the other dialect of English.
394 wxSizerFlags
& Centre();
397 Sets the border in the given @a direction having twice the default
400 wxSizerFlags
& DoubleBorder(int direction
= wxALL
);
403 Sets the border in left and right directions having twice the default
406 wxSizerFlags
& DoubleHorzBorder();
409 Sets the object of the wxSizerFlags to expand to fill as much area as
412 wxSizerFlags
& Expand();
415 Set the @c wxFIXED_MINSIZE flag which indicates that the initial size
416 of the window should be also set as its minimal size.
418 wxSizerFlags
& FixedMinSize();
421 Set the @c wxRESERVE_SPACE_EVEN_IF_HIDDEN flag. Normally wxSizers
422 don't allocate space for hidden windows or other items. This flag
423 overrides this behavior so that sufficient space is allocated for the
424 window even if it isn't visible. This makes it possible to dynamically
425 show and hide controls without resizing parent dialog, for example.
429 wxSizerFlags
& ReserveSpaceEvenIfHidden();
432 Returns the border used by default in Border() method.
434 static int GetDefaultBorder();
437 Aligns the object to the left, shortcut for @c Align(wxALIGN_LEFT)
441 wxSizerFlags
& Left();
444 Sets the proportion of this wxSizerFlags to @e proportion
446 wxSizerFlags
& Proportion(int proportion
= 0);
449 Aligns the object to the right, shortcut for @c Align(wxALIGN_RIGHT)
453 wxSizerFlags
& Right();
456 Set the @c wx_SHAPED flag which indicates that the elements should
457 always keep the fixed width to height ratio equal to its original value.
459 wxSizerFlags
& Shaped();
462 Aligns the object to the top, shortcut for @c Align(wxALIGN_TOP)
469 Sets the border in the given @a direction having thrice the default
472 wxSizerFlags
& TripleBorder(int direction
= wxALL
);
478 @class wxNotebookSizer
482 This class is deprecated and should not be used in new code! It is no
483 longer needed, wxNotebook control can be inserted
484 into any sizer class and its minimal size will be determined correctly.
486 wxNotebookSizer is a specialized sizer to make sizers work in connection
487 with using notebooks. This sizer is different from any other sizer as you
488 must not add any children to it - instead, it queries the notebook class
489 itself. The only thing this sizer does is to determine the size of the
490 biggest page of the notebook and report an adjusted minimal size to a more
496 @see wxSizer, wxNotebook,
497 @ref overview_sizer "Sizers overview"
499 class wxNotebookSizer
: public wxSizer
503 Constructor. It takes an associated notebook as its only parameter.
505 wxNotebookSizer(wxNotebook
* notebook
);
508 Returns the notebook associated with the sizer.
510 wxNotebook
* GetNotebook();
516 @class wxFlexGridSizer
519 A flex grid sizer is a sizer which lays out its children in a two-dimensional
520 table with all table fields in one row having the same
521 height and all fields in one column having the same width, but all
522 rows or all columns are not necessarily the same height or width as in
525 Since wxWidgets 2.5.0, wxFlexGridSizer can also size items equally in one
526 direction but unequally ("flexibly") in the other. If the sizer is only
527 flexible in one direction (this can be changed using
528 wxFlexGridSizer::SetFlexibleDirection),
529 it needs to be decided how the sizer should grow in the other ("non-flexible")
530 direction in order to fill the available space. The
531 wxFlexGridSizer::SetNonFlexibleGrowMode method
537 @see wxSizer, @ref overview_sizeroverview "Sizer overview"
539 class wxFlexGridSizer
: public wxGridSizer
544 Constructor for a wxGridSizer. @a rows and @a cols determine the number of
545 columns and rows in the sizer - if either of the parameters is zero, it will be
546 calculated to form the total number of children in the sizer, thus making the
547 sizer grow dynamically. @a vgap and @a hgap define extra space between
550 wxFlexGridSizer(int rows
, int cols
, int vgap
, int hgap
);
551 wxFlexGridSizer(int cols
, int vgap
= 0, int hgap
= 0);
555 Specifies that column @a idx (starting from zero) should be grown if
556 there is extra space available to the sizer.
557 The @a proportion parameter has the same meaning as the stretch factor for
558 the sizers() except that if all proportions are 0,
559 then all columns are resized equally (instead of not being resized at all).
561 void AddGrowableCol(size_t idx
, int proportion
= 0);
564 Specifies that row idx (starting from zero) should be grown if there
565 is extra space available to the sizer.
566 See AddGrowableCol() for the description
567 of @a proportion parameter.
569 void AddGrowableRow(size_t idx
, int proportion
= 0);
572 Returns a wxOrientation value that specifies whether the sizer flexibly
573 resizes its columns, rows, or both (default).
575 @returns One of the following values:
577 @see SetFlexibleDirection()
579 int GetFlexibleDirection() const;
582 Returns the value that specifies how the sizer grows in the "non-flexible"
583 direction if there is one.
585 @returns One of the following values:
587 @see SetFlexibleDirection(),
588 SetNonFlexibleGrowMode()
590 int GetNonFlexibleGrowMode() const;
593 Specifies that column idx is no longer growable.
595 void RemoveGrowableCol(size_t idx
);
598 Specifies that row idx is no longer growable.
600 void RemoveGrowableRow(size_t idx
);
603 Specifies whether the sizer should flexibly resize its columns, rows, or
604 both. Argument @c direction can be @c wxVERTICAL, @c wxHORIZONTAL
605 or @c wxBOTH (which is the default value). Any other value is ignored. See
606 @ref getflexibledrection() GetFlexibleDirection for the
607 explanation of these values.
608 Note that this method does not trigger relayout.
610 void SetFlexibleDirection(int direction
);
613 Specifies how the sizer should grow in the non-flexible direction if
615 SetFlexibleDirection() must have
616 been called previously). Argument @a mode can be one of those documented in
617 GetNonFlexibleGrowMode(), please
618 see there for their explanation.
619 Note that this method does not trigger relayout.
621 void SetNonFlexibleGrowMode(wxFlexSizerGrowMode mode

630 wxSizer is the abstract base class used for laying out subwindows in a window.
632 cannot use wxSizer directly; instead, you will have to use one of the sizer
633 classes derived from it. Currently there are wxBoxSizer,
640 The layout algorithm used by sizers in wxWidgets is closely related to layout
641 in other GUI toolkits, such as Java's AWT, the GTK toolkit or the Qt toolkit.
643 based upon the idea of the individual subwindows reporting their minimal
645 size and their ability to get stretched if the size of the parent window has
647 This will most often mean that the programmer does not set the original size of
648 a dialog in the beginning, rather the dialog will be assigned a sizer and this
650 will be queried about the recommended size. The sizer in turn will query its
651 children, which can be normal windows, empty space or other sizers, so that
652 a hierarchy of sizers can be constructed. Note that wxSizer does not derive
654 and thus does not interfere with tab ordering and requires very little
656 to a real window on screen.
658 What makes sizers so well fitted for use in wxWidgets is the fact that every
660 reports its own minimal size and the algorithm can handle differences in font
662 or different window (dialog item) sizes on different platforms without
664 the standard font as well as the overall design of Motif widgets requires more
666 on Windows, the initial dialog size will automatically be bigger on Motif than
669 Sizers may also be used to control the layout of custom drawn items on the
670 window. The Add(), Insert(), and Prepend() functions return a pointer to
671 the newly added wxSizerItem. Just add empty space of the desired size and
672 attributes, and then use the wxSizerItem::GetRect() method to determine
673 where the drawing operations should take place.
675 Please notice that sizers, like child windows, are owned by the library and
676 will be deleted by it which implies that they must be allocated on the
677 heap. However if you create a sizer and do not add it to another sizer or
678 window, the library wouldn't be able to delete such an orphan sizer and in
679 this, and only this, case it should be deleted explicitly.
681 @b wxPython note: If you wish to create a sizer class in wxPython you should
682 derive the class from @c wxPySizer in order to get Python-aware
683 capabilities for the various virtual methods.
685 @anchor wxsizer_flags
687 The "flag" argument accepted by wxSizeItem constructors and other
688 functions, e.g. wxSizer::Add(), is OR-combination of the following flags.
689 Two main behaviours are defined using these flags. One is the border around
690 a window: the border parameter determines the border width whereas the
691 flags given here determine which side(s) of the item that the border will
692 be added. The other flags determine how the sizer item behaves when the
693 space allotted to the sizer changes, and is somewhat dependent on the
694 specific kind of sizer used.
701 These flags are used to specify which side(s) of the sizer item
702 the border width will apply to.}
704 The item will be expanded to fill the space assigned to the item.}
706 The item will be expanded as much as possible while also
707 maintaining its aspect ratio.}
708 @itemdef{wxFIXED_MINSIZE,
709 Normally wxSizers will use GetAdjustedBestSize() to determine what
710 the minimal size of window items should be, and will use that size
711 to calculate the layout. This allows layouts to adjust when an
712 item changes and its best size becomes different. If you would
713 rather have a window item stay the size it started with then use
715 @itemdef{wxRESERVE_SPACE_EVEN_IF_HIDDEN,
716 Normally wxSizers don't allocate space for hidden windows or other
717 items. This flag overrides this behavior so that sufficient space
718 is allocated for the window even if it isn't visible. This makes
719 it possible to dynamically show and hide controls without resizing
720 parent dialog, for example. (Available since 2.8.8.)

729 wxALIGN_CENTRE_VERTICAL<br>
730 wxALIGN_CENTER_HORIZONTAL<br>

788 Although the meaning of this parameter is undefined in wxSizer, it
789 is used in wxBoxSizer to indicate if a child of a sizer can change
790 its size in the main orientation of the wxBoxSizer - where 0 stands
791 for not changeable and a value of more than zero is interpreted
792 relative to the value of other children of the same wxBoxSizer. For
793 example, you might have a horizontal wxBoxSizer with three
794 children, two of which are supposed to change their size with the
795 sizer. Then the two stretchable windows would get a value of 1 each
796 to make them grow and shrink equally with the sizer's horizontal
799 OR-combination of flags affecting sizer's behavior. See
800 @ref wxsizer_flags "wxSizer flags list" for details.
802 Determines the border width, if the flag parameter is set to
803 include any border flag.
805 Allows an extra object to be attached to the sizer item, for use in
806 derived classes when sizing information is more complex than the
807 proportion and flag will allow for.
809 wxSizerItem
* Add(wxWindow

822 The (child-)sizer to be added to the sizer. This allows placing a
823 child sizer in a sizer and thus to create hierarchies of sizers

875 in the derived classes that you will instantiate to use it so they are
878 @a width and @a height specify the dimension of a spacer to be added to
879 the sizer. Adding spacers to sizers gives more flexibility in the
880 design of dialogs; imagine for example a horizontal box with two
881 buttons at the bottom of a dialog: you might want to insert a space
882 between the two buttons and make that space stretchable using the
883 proportion flag and the result will be that the left button will be
884 aligned with the left side of the dialog and the right button with the
885 right side - the space in between will shrink and grow with the dialog.
890 Height of the spacer.
892 Although the meaning of this parameter is undefined in wxSizer, it
893 is used in wxBoxSizer to indicate if a child of a sizer can change
894 its size in the main orientation of the wxBoxSizer - where 0 stands
895 for not changeable and a value of more than zero is interpreted
896 relative to the value of other children of the same wxBoxSizer. For
897 example, you might have a horizontal wxBoxSizer with three
898 children, two of which are supposed to change their size with the
899 sizer. Then the two stretchable windows would get a value of 1 each

922 wxSizerItem
* AddSpacer(int size
);
925 Adds stretchable space to the sizer. More readable way of calling
926 wxSizer::Add(0, 0, prop).
928 wxSizerItem
* AddStretchSpacer(int prop
= 1);
931 This method is abstract and has to be overwritten by any derived class.
932 Here, the sizer will do the actual calculation of its children's minimal sizes.

938 child windows will also be deleted.
940 void Clear(bool delete_windows
= false);
943 Computes client area size for @a window so that it matches the sizer's
944 minimal size. Unlike GetMinSize(), this method accounts for other
945 constraints imposed on @e window, namely display's size (returned size
946 will never be too large for the display) and maximum window size if
947 previously set by wxWindow::SetMaxSize(). The returned value is
948 suitable for passing to wxWindow::SetClientSize() or
949 wxWindow::SetMinClientSize().
953 @see ComputeFittingWindowSize(), Fit()

958 Like ComputeFittingClientSize(), but converts the result into window
959 size. The returned value is suitable for passing to wxWindow::SetSize()

970 Detach a child from the sizer without destroying it. @a window is the window to
972 detached, @a sizer is the equivalent sizer and @a index is the position of
973 the child in the sizer, typically 0 for the first item. This method does not
974 cause any layout or resizing to take place, call Layout()
975 to update the layout "on screen" after detaching a child from the sizer.
976 Returns @true if the child item was found and detached, @false otherwise.
980 bool Detach(wxWindow
* window

999 Tell the sizer to resize the virtual size of the @a window to match the sizer's
1000 minimal size. This will not alter the on screen size of the window, but may

1038 Finds item of the sizer which has the given @e id. This @a id is not the
1039 window id but the id of the wxSizerItem itself. This is mainly useful for
1040 retrieving the sizers created from XRC resources.
1041 Use parameter @a recursive to search in subsizers too.
1042 Returns pointer to item or @NULL.
1044 wxSizerItem

1047 Returns the minimal size of the sizer. This is either the combined minimal
1048 size of all the children and their borders or the minimal size set by
1049 SetMinSize(), depending on which is bigger.
1050 Note that the returned value is client size, not window size.
1051 In particular, if you use the value to set toplevel window's minimal or
1052 actual size, use wxWindow::SetMinClientSize
1053 or wxWindow::SetClientSize, not
1054 wxWindow::SetMinSize
1055 or wxWindow::SetSize.

1207 This method is abstract and has to be overwritten by any derived class.
1208 Here, the sizer will do the actual calculation of its children's
1209 positions and sizes.
1214 Removes a child window from the sizer, but does @b not destroy it
1215 (because windows are owned by their parent window, not the sizer).
1218 The overload of this method taking a wxWindow* parameter
1219 is deprecated as it does not destroy the window as would usually be
1220 expected from Remove(). You should use Detach() in new code instead.
1221 There is currently no wxSizer method that will both detach and destroy

1265 The detached child is removed @b only if it is a sizer or a spacer
1266 (because windows are owned by their parent window, not the sizer).
1267 Use parameter @a recursive to search the given element recursively in subsizers.
1269 This method does not cause any layout or resizing to take place, call
1270 Layout() to update the layout "on screen" after replacing a
1271 child from the sizer.

1302 Call this to give the sizer a minimal size. Normally, the sizer will
1303 calculate its minimal size based purely on how much space its children
1304 need. After calling this method GetMinSize() will return either the
1305 minimal size as requested by its children or the minimal size set here,
1306 depending on which is bigger.

1316 This method first calls Fit() and then
1317 wxTopLevelWindow::SetSizeHints on the @e window
1318 passed to it. This only makes sense when @a window is actually a
1319 wxTopLevelWindow such as a wxFrame or a
1320 wxDialog, since SetSizeHints only has any effect in these classes.
1321 It does nothing in normal windows or controls.
1322 This method is implicitly used by wxWindow::SetSizerAndFit
1323 which is commonly invoked in the constructor of a toplevel window itself (see
1324 the sample in the description of wxBoxSizer) if the
1325 toplevel window is resizable.
1327 void SetSizeHints(wxWindow

1341 Shows or hides the @e window, @e sizer, or item at @e index.
1342 To make a sizer item disappear or reappear, use Show() followed by Layout().

1362 A grid sizer is a sizer which lays out its children in a two-dimensional
1363 table with all table fields having the same size,
1364 i.e. the width of each field is the width of the widest child,
1365 the height of each field is the height of the tallest child.
